Maxillofacial infections of dental origin: risk factors for hospital admission

Aim: to evaluate the occurrence of maxillofacial infection cases, which were treated at local hospital, identifying the main risk factors that determine the need for hospitalization of patients and the factors associated with staying length. Methods: A retrospective review of 191 records of patients with maxillofacial infection of odontogenic origin was performed, statistically evaluated by frequency and percentage of involvement, p values (based on the chi-square test) and odds ratio with a 95% confidence interval. A p-value <0.05 was considered statistically significant. Results: Among all the 191 patients, 31 had some harmful habits, such as smokers (13%) and alcoholics (1%). In addition, 39 patients reported some general health problem, such as systemic arterial hypertension (8.3%), depression (6.8%), diabetes (3.6%) and some immunosuppression (1.57%). Involvement of infection in deep facial spaces was present, with 119 patients presenting a deeper infection (62.3%) and 72 patients a superficial infection (37.7%). The most prevalent clinical signs and symptoms in the initial evaluation were pain (91.1%) and edema (90.1%), followed by erythema/hyperemia (44.5%), trismus (37.7%), abscess (30.9%), cellulitis (27.7%), f istula (16.8%), fever (16.8%), dysphagia (11%), dehydration (9.9%), odynophagia (7.9% ) and dyspnea (3.7%). Pulp necrosis was considered a risk factor for treatment in a hospital environment (0.032) and root canal treatment decreases the risk of hospitalization (p=0.002). Considering the evaluated patients, 146 (76.4%) were admitted and 45 (37.7%) were not admitted for hospitalization after initial clinical evaluation. Conclusion: there is a high occurrence of maxillofacial infection cases of dental origin, considering that involvement of infection in deeper facial spaces, as well as presence of pain, edema, erythema/hyperemia, trismus, abscess, cellulitis and pulp necrosis, represent the main risk factors for hospitalization and staying length

Resolución Quirúrgica para Un Caso de Polisinusitis de Origen Odontogénico / Surgical Resolution for A Case of Polysinusitis of Odontogenic Origin

La celulitis orbitaria es una patología grave que está asociada con sinusitis paranasal. Éstas suelen presentar edema periorbitario, dolor, y movimiento extraocular restringido. La mayoría de los casos presentan pronóstico favorable, asociado a terapia antibiótica o drenaje quirúrgico. Las celulitis de origen odontogénico representan 2 a 5 % de todos los casos; se caracterizan por una diseminación del proceso infeccioso desde los ápices de las raíces, infectando al seno maxilar, llegando a la órbita a través de la fisura orbitaria inferior o a través de un defecto en el piso de la órbita. En el presente estudio se reporta el caso de un paciente masculino de 28 años que consulta por aumento de volumen periorbitario izquierdo con 4 días de evolución, posterior a exodoncia de segundo molar superior izquierdo. Al examen extraoral presenta aumento de volumen izquierdo con eritema periorbitario, proptosis ocular ipsilateral con visión conservada, y salida de líquido purulento por fosa nasal izquierda. En los exámenes de laboratorio e imagenológicos se pesquisa compromiso de seno maxilar, etmoidal y esfenoidal, decidiendo su hospitalización y manejo quirúrgico en tres tiempos operatorios, los cuales permiten acceso a pared anterior del seno maxilar y a espacio pterigoideo. Dentro de los diagnósticos de celulitis orbitaria pueden incluir reacciones alérgicas, conjuntivitis o herpes. Se excluyeron los diagnósticos mencionados debido a que no se observaron alteraciones dermocutáneas periorbitarias. Por el contrario, el compromiso unilateral, movimiento ocular alterado y doloroso indica que el cuadro abarcaba espacios profundos. La infección de senos paranasales posterior a una exodoncia es una complicación poco frecuente. Un diagnóstico temprano adecuado disminuye la morbilidad y mortalidad de esta condición. Debemos estar alertas a complicaciones posteriores en procedimientos realizados, tener conocimiento en diagnóstico y manejo de posibles evoluciones tórpidas en pacientes.

Orbital cellulitis is a serious pathology that is associated with paranasal sinusitis. These medical conditions usually present with periorbital edema, pain, and restricted extraocular movement. Most cases have a favorable prognosis, associated with antibiotic therapy or surgical drainage. Cellulitis of odontogenic origin represents 2 to 5 % of all cases. They are characterized by a spread of the infectious process from the apices of the roots, infecting the maxillary sinus, reaching the orbit through the inferior orbital fissure or through a defect in the floor of the orbit. The present study reports the case of a 28-year-old male patient, who consulted for a volume increase in left periorbital volume with 4 days of evolution, after extraction of the upper left second molar. Extraoral examination showed left volume increase with periorbital erythema, ipsilateral ocular proptosis with preserved vision, and discharge of purulent fluid from the left nostril. The laboratory and imaging tests showed compromise of the maxillary, ethmoid and sphenoid sinus deciding on hospitalization and surgical management in three operative times, which allow access to the anterior wall of the maxillary sinus and the pterygoid space. Diagnoses of orbital cellulitis may include allergic reactions, conjunctivitis, or herpes. These diagnoses were excluded because no periorbital dermocutaneous alterations were observed. In contrast, unilateral involvement, impaired eye movement, and pain indicate that the condition involved deep spaces. Paranasal sinus infection after tooth extraction is a rare complication. An early diagnosis adequately decreases the morbidity and mortality of this condition. We must be alert to subsequent complications in procedures performed, have knowledge in diagnosis and management of possible torpid evolutions in patients.

Aspectos clínico-epidemiológicos en pacientes con abscesos odontogénicos cervicofaciales y factores asociados para estancia hospitalaria corta / Clinical-epidemiological aspects in patients with cervicofacial odontogenic abscesses and associated factors for short hospital stay

Introducción: en todo paciente hospitalizado con absceso odontogénico cervicofacial se busca resolución pronta del absceso, pero es necesario conocer cuáles son los factores que favorecen la resolución en hospitalizaciones cortas (1-3 días). Objetivo: determinar factores clínico-epidemiológicos de pacientes con abscesos odontogénicos para identificar factores que correlacionan con hospitalización corta. Material y métodos: estudio transversal, retrospectivo, observacional y analítico de 100 pacientes con abscesos odontogénicos en un Hospital General de Zona del Instituto Mexicano del Seguro Social de los años 2012-2013. Variables de estudio: días de hospitalización, sexo, edad, comorbilidades, conteo leucocitario, trismus, diente causal, región afectada y tratamientos realizados. Tamaño de muestra obtenido con fórmula para estudios observaciones con manejo de prevalencias para poblaciones infinitas, se empleó χ2 para identificar factores que correlacionan con hospitalización corta. Resultados: mujeres 56%, rango de edad 12-89 años y de hospitalización de 1-23 días; con comorbilidades 56%, leucocitosis 39% y trismus 21%. La caries causó 64% de abscesos, molares inferiores 70% y región submandibular afectada 73%. Variables estadísticamente significativas; conteo leucocitario, diente causal y región afectada. Conclusión: factores correlacionados con hospitalización corta: conteo leucocitario menor a 10,500 leucocitos, que el molar inferior no sea el diente causal y que la región submandibular no esté afectada (AU)

Introduction: prompt resolution of the abscess is sought in all patients hospitalized with cervicofacial odontogenic abscess, but which factors favor this resolution in short hospitalizations (1-3 days). Objective: determine clinical-epidemiological factors of patients with odontogenic abscesses to identify factors that correlate with short hospitalization. Material and methods: crosssectional, retrospective, observational and analytical study of 100 patients with odontogenic abscesses in a General Hospital of the Zone of the Mexican Social Security Institute from 2012-2013. Study variables; days of hospitalization, sex, age, comorbidities, leukocyte count, trismus, causative tooth, affected region and treatments performed. Sample size obtained with the formula for observational studies with prevalence management for infinite populations, χ2 was used to identify factors that correlate with short hospitalization. Results: women 56%, age range 12-89 years and hospitalization of 1-23 days, with comorbidities 56%, leukocytosis 39% and trismus 21%. Caries caused 64% of abscesses, lower molars 70% and affected submandibular region 73%. Statistically significant variables; leukocyte count, causative tooth and affected region. Conclusion: factors correlated with short hospitalization; leukocyte count less than 10,500 leukocytes, that the lower molar is not the causal tooth and that the submandibular region is not affected.

Estado actual de la infección focal y del éxito del tratamiento endodóntico / Current status of focal infection and the success of endodontic treatment

Frente a la difusión en medios de comunicación de medias verdades con enunciados alarmantes y anticientíficos, este editorial busca revisar las bases científicas para determinar el comportamiento clínico. Así, el texto discurre por el concepto de infección focal desde su origen, yendo al encuentro de sus transformaciones conceptuales a través de los descubrimien- tos científicos, teniendo en cuenta las características emocio- nales propias de cada paciente como un todo y los peligros a los que se puede estar expuestos frente a las medias verdades (AU)

Facing the diffusion of alarming and anti-scientific state- ments in the media, this editorial seeks the scientific bases to determine the clinical behavior. Thus, the text runs through the concept of focal infection from its origin and across its conceptual transformations through scientific discoveries, by considering the emotional characteristics of each patient as a whole and the dangers to which they may be exposed in the face of half-truths (AU)

Lesiones perirradiculares persistentes: revisión narrativa / Persistent periradicular lesions: a narrative review

La persistencia de lesiones perirradiculares luego del tra- tamiento endodóntico es un problema que requiere del clínico un conocimiento cabal de la histofisiología y de la histopato- logía del sistema de conductos radiculares del tejido pulpar y de los tejidos perirradiculares (periodonto y hueso); además de considerar siempre la posible existencia de enfermedades sistémicas que también pueden actuar como factores de in- fluencia. La presencia de bacterias remanentes a posteriori del tratamiento es considerada como una de las causas principales y más frecuentes para la perpetuación de las lesiones perirra- diculares. Sin embargo, existen otros factores causales, como la existencia de conductos laterales o accesorios infectados y no tratados, la reabsorción dentinaria interna, intercomunica- ciones, cul-de-sacs o istmos; que representan áreas de difícil acceso durante la instrumentación e irrigación. Cuando la cau- sa original se localiza en la zona perirradicular, como en los casos de actinomicosis, reacciones a cuerpo extraño, cristales de colesterol (CRCo) y granulomas o quistes con alto conte- nido de CRCo, la indicación más adecuada es el retratamiento y la cirugía periapical como complemento (AU)

The persistence of periradicular lesions after endodontic treatment is a problem that requires the doctor to have a thor- ough knowledge of the histophysiology and histopathology of the root canal system, the pulp tissue and periradicular tis- sues (periodontium and bone); as well as always considering the possible existence of systemic alterations that can also be influencing factors. Persisting bacteria within the root canal system after treatment is one of the major and most frequent causes for the perpetuation of periradicular lesions. Howev- er, there are other possible causal factors such as the exist- ence of untreated lateral or accessory canals, internal dentin resorption, intercommunications, cul-de-sacs or isthmuses; areas that represent a difficulty in access during instrumen- tation and irrigation. If the original cause is located in the periradicular area, in cases like actinomycosis, foreign-body reactions, cholesterol crystals (CRCo) and granulomas or cysts with high content of CRCo, retreatment coupled with periapical surgery is the best approach to treatment (AU)

Diagnóstico y tratamiento de las fístulas cutáneas odontogénicas: revisión sistemática / Diagnosis and treatment of odontogenic cutaneous sinus tracts: a systematic review

Se realizó una revisión sistemática de la literatura científica en relación con las variantes de tratamien-to que recibieron las piezas dentarias permanentes asociadas a la presencia de una fístula cutánea. Se incluyeron reportes de casos clínicos en inglés, pu-blicados en los últimos diez años. Se obtuvieron 481 artículos, 359 excluidos por escasez de datos en títu-lo e incumplimiento de criterios de selección. Se ex-cluyeron 89 por carecer de tratamiento. Se incluye-ron 33 artículos. Se analizaron fístulas de 45 piezas dentarias, superiores e inferiores, anteriores y pos-teriores. En base a los resultados obtenidos se llegó a la conclusión de que las fístulas cutáneas faciales de origen odontogénico se diagnostican de manera errónea; esto conduce a un tratamiento inadecuado y secuela estéticas. Realizar un correcto diagnóstico y adecuado plan de tratamiento permite una curación rápida y predecible. Los hallazgos obtenidos estable-cen que realizar un correcto tratamiento endodóntico en la pieza afectada, es la terapéutica adecuada para lograr el cierre definitivo de la fístula, sin necesidad de tratar quirúrgicamente la misma (AU)

A systematic review of the scientific literature was carried out in relation to the variants of treatment received by permanent teeth associated with the presence of a cutaneous sinus tract. Clinical case reports in English, published in the last ten years, were included. A total of 481 articles were obtained, 359 were excluded due to lack of title data and non-compliance with selection criteria. 89 were excluded due to lack of treatment. 33 articles were included Cutaneous sinus tracts of 45 teeth, upper and lower, anterior and posterior, were analyzed. Based on the results obtained, it was concluded that facial cutaneous sinus tracts of odontogenic origin are misdiagnosed, leading to inadequate treatment and aesthetic sequelae. Carrying out a correct diagnosis and adequate treatment plan allows a quick and predictable healing. The findings obtained establish that performing a correct endodontic treatment in the affected piece is the appropriate therapy to achieve the definitive closure of the cutaneous sinus tract, without the need to surgically treatment (AU)

Multiple Brain Abscesses Secondary to Odontogenic Infection: A Clinical Case Report

Introduction Cerebral abscess is a suppurative infection of the cerebral parenchyma, which may occur due to contiguity, hematogenous dissemination of distant foci, secondary to open traumatic brain injuries, or be idiopathic. Clinical Case A 63-year-old male patient sought assistance due to a severe headache in the frontal region associated with chills and lack of appetite that started four days before. Clinical examination of the patient showed no significant changes. Imaging and laboratory tests on admission showed only nonspecific changes, such as leukocytes 18,540, platelets 517,000, and c-reactive protein 2,0. In such case,magnetic resonance imaging (MRI) of the skull was performed with contrast, showing the presence of expansive lesions compatible with multiple brain abscesses in the right parietooccipital region. Discussion After excluding the main focus of hematogenous dissemination and in view of the identification of the agent Streptococcus intermedius by means of secretion culture collected through a surgical method, the hypothesis of abscess due to contiguous dental pyogenic foci was pointed out. Conclusion Dental evaluation showed multiple foci of infection with periodontitis and dental abscess, which were treated along with the use of antibiotics directed to the etiologic agent.

Conclusion: The results highlight the need to have dental emergency services in the AMBA area that have qualified and trained human resources to solve the surgical type emergencies that may arise (AU)

Mediastinitis necrotizante descendente de origen odontogénico / Descending necrotizing mediastinitis of odontogenic origin

Resumen Introducción: El tratamiento inoportuno e ineficaz de las infecciones odontogénicas puede causar complicaciones potencialmente mortales como la mediastinitis necrotizante descendente (MND). La MDN es una infección grave que afecta al cuello-tórax, con una alta tasa de mortalidad por sepsis e insuficiencia orgánica si no se trata de manera rápida y efectiva. Objetivo: Describir un caso de MND de origen odontogénico y su manejo médico-quirúrgico. Caso clínico: Presentamos un paciente de sexo masculino de 34 años que ingresa con un cuadro infeccioso agudo de origen odontogénico, que compromete espacios de la cabeza, cuello y tórax (mediastino superior), el cual se trata exitosamente. Discusión: Las infecciones odontogénicas son generalmente localizadas y que se pueden tratar mediante terapias convencionales. A pesar de esto, si estas infecciones no pueden controlarse, ya sea por no realización de tratamientos oportunos o por estados inmunosuprimidos del paciente, se pueden desarrollar diferentes complicaciones como la MND. Conclusión: Un diagnóstico rápido, el tratamiento quirúrgico agresivo, la terapia antibiótica adecuada y la atención de apoyo son los pilares fundamentales para el manejo de la MND.

Introduction: Inappropriate and ineffective treatment of odontogenic infections can cause life-threatening complications such as Descending Necrotizing Mediastinitis (MND). MDN is a serious infection that affects the neck-thorax, with a high mortality rate from sepsis and organ failure if it is not treated quickly and effectively. Aim: To describe a case of MND of odontogenic origin and its medical-surgical management. Case report: We present a 34-year-old male patient who is admitted with an acute infectious condition of odontogenic origin, which compromises spaces of the head, neck and thorax (upper mediastinum), which is treated successfully. Discussion: Odontogenic infections are generally localized and can be treated by conventional therapies. In spite of this, if these infections cannot be controlled, either by not carrying out appropriate treatments or by immunosuppressed states of the patient, different complications such as MND can develop. Conclusion: A rapid diagnosis, aggressive surgical treatment, adequate antibiotic therapy and supportive care are the fundamental pillars for the management of MND.

Odontogenic Maxillofacial Infections in a High-level Hospital: Orofacial Pain and Related Conditions

ABSTRACT Objective: Odontogenic infection is a common condition in America; the aim of this research was to determine the profile of odontogenic maxillofacial infections and to identify the link between these and the pain felt by patients admitted to the emergency dental service of the Hernân Henriquez Aravena Hospital in Temuco, Chile. Methods: A cross-sectional, double-blind study analysed 49 individuals admitted for emergency dental care. Included were admissions associated with odontogenic infection identified by clinical examination, establishing a relation to pain through a survey. The diagnosis was made clinically using the fascial spaces involved in the infection, presence of self-medication prior to admission, need for surgical treatment and the patient 's systemic conditions. The data were analysed using descriptive statistics, Chi-squared, ANOVA, considering a value of p < 0.05 as significant. Results: The average pain level measured by visual analogue scale (VAS) in emergency admission was 8.1. There was no association between the diagnosis (pulp infection, periodontal infection or pericoronitis) and the VAS (p = 0.078), but there was association between age and the diagnosis (p = 0.022), and the VAS was associated with pain compared to other types of pathologies or traumas (p = 0.011). Conclusion: Odontogenic infection is frequent and linked to age and high-pain values. New public policies should be adopted based on these results. New studies are needed to assess new variables associated with these pathologies.

Ideas previas de estudiantes de Odontología respecto al manejo de infecciones odontogénicas en niños / Previous ideas about the management of odontogenic infections in children for dental students

Objetivo: indagar por las ideas previas que presentan los estudiantes de Odontología, que se encuentran cursando entre V a X semestre, respecto al manejo ambulatorio de infecciones odontogénicas ­IO- en niños. Métodos: se aplicó un estudio cualitativo-interpretativo con la participación de 60 estudiantes. Las respuestas dadas en una entrevista semiestructurada, la cual contó con ocho preguntas guía abiertas, fueron la unidad de análisis. El procedimiento tuvo cuatro fases. En la primera, preparatoria, se construyó el marco teórico-conceptual como base para interpretar lo manifestado por los estudiantes y se elaboraron las preguntas-guía; para la segunda fase, de recolección de información, se realizaron las entrevistas semiestructuradas presenciales, para ello, los participantes se citaron individualmente en la oficina de investigación. Durante la fase analítica se establecieron las categorías previas: concepto, etiología, evolución, manejo ambulatorio, vías de diseminación, tratamiento farmacológico. La información recabada se vació, depuró y codificó para hacer la exploración con técnica interpretativa y análisis de contenido. En la cuarta fase, de reporte, se presentó un informe con los resultados. Resultados: los estudiantes reconocen que esta enfermedad afecta a pacientes de cualquier edad, sexo y con condición sistemática comprometida. Conclusiones: se requiere una estrategia educativa que permita afianzar el manejo ambulatorio de las IO desde lo propuesto por la ciencia para lograr un aprendizaje significativo. Se requiere enfatizar en el manejo ambulatorio del paciente con infección odontogénica.

Objective: To investigate the previous ideas of dental students from the 5th to the 10th semester about the outpatient management of odontogenic infections in children. Methods: Qualitative-interpretive study, with the participation of 60 students. The unit of analysis was the answers given in a semi-structured interview that had eight open-ended questions. The procedure had four phases: Preparatory where the theoretical-conceptual framework was built as a basis for interpreting what was stated by the students, the guiding questions were elaborated. Information gathering: The face-to-face semi-structured interviews were carried out; the participants were cited individually in the research office. Analytical: they were established as previous categories: concept, etiology, evolution, outpatient management, routes of dissemination, pharmacological treatment. The information collected was emptied, refined and encoded, to make the exploration with interpretive technique and content analysis and Report: a report was submitted with the results. Results: The students recognize that this disease affects patients of any age, sex and with a compromised systemic condition. Conclusions: An educational strategy is required that allows to consolidate the outpatient management of IO them from what is proposed by science to achieve meaningful learning. In the case of antibiotic therapy, students are clear about what is done and how long it will last. Emphasis is required on the outpatient management of the patient with odontogenic infection, as long as a good diagnosis is made.

Mediastinitis necrotizante descendente de origen dental: revisión de la literatura y presentación de un caso / Descending necrotizing mediastinitis of dental origin: a case study and review of the literature

La mediastinitis se define como una inflamación aguda severa de los tejidos conectivos ubicados en la cavidad torácica media, en la que 20% de los casos puede implicar una infección difusa y polimicrobiana del mediastino denominada mediastinitis necrotizante descendente (MND), secundaria a la propagación de una infección grave desde los tejidos bucofaríngeos o cervicales tales como infecciones odontogénicas (de 36 a 47%), faríngeas (de 33 a 45%), cervicales (15%) y otras infecciones de cabeza y cuello (5%). Clínicamente, los pacientes presentan aumento de volumen, temblores, trismus, odinofagia con disnea, disfagia, hipotensión, dolor de cuerpo y del ángulo de la mandíbula. Puede observarse signo de Hamman (crepitación mediastinal con el latido cardiaco) y enfisema subcutáneo. El manejo quirúrgico de las infecciones odontogénicas, sin importar su severidad, consta de dos principios: eliminar el foco etiológico y el vaciamiento quirúrgico de los espacios anatómicos comprometidos con la instalación de un drenaje adecuado. Se presenta el caso de un masculino de 60 años con diagnóstico de mediastinitis necrotizante descendente de origen dental (AU)

Mediastinitis is defined as a severe acute inflammation of the connective tissues affected in the middle thoracic cavity, in which 20% of cases may involve a diffuse and polymicrobial infection of the mediastinum, descending necrotizing mediastinitis (MND), secondary to the spread of a serious infection from the oropharyngeal or cervical tissues, stories such as odontogenic infections (36 to 47%), pharyngeal (33 to 45%), cervical (15%) and other head and neck infections (5%). Clinically, patients present with increased volume, tremors, trismus, odynophagia with dyspnea, dysphagia, hypotension, pain in the body and in the angle of the jaw. Hamman sign (mediastinal crepitus with heartbeat) and subcutaneous emphysema may be observed. The surgical management of odontogenic infections, regardless of their severity, consists of two principles: eliminate the etiological focus and the surgical emptying of the anatomical spaces compromised with the installation of adequate drainage. We present the case of a 60-year-old man diagnosed with descending necrotizing (AU)

Changes in Vital Signs and Laboratory Tests in Patients with Odontogenic Infections Requiring Hospitalization / Cambios en los Signos Vitales y Pruebas de Laboratorio en Pacientes con Infecciones Odontogénicas que Requirieron Hospitalización

ABSTRACT: The purpose of this study was to evaluate the changes in vital signs and laboratory tests of patients with odontogenic infections who required hospitalization as well as checking their effectiveness in determining the severity of the case and possible correlations with the length of stay. Patients with odontogenic infections who required hospitalization were assessed prospectively between October 2016 and April 2018. The patients were divided into two groups considered as simple (Group 1) or complex (Group 2) cases according to the length of stay. The personal data, comorbidities, signs and symptoms, vital signs and laboratory tests were analyzed. In this study, 84 cases of maxillofacial infections were detected and 50 cases of odontogenic infections were included. There were significant increases in heart rate (p = 0.012), leukocytosis (p = 0.037), neutrophilia (p = 0.021), neutrophil/lymphocyte (N/L) ratio (p = 0.044) and C-reactive protein (CRP) levels (p = 0.004) in Group 2. Additionally, there were positive correlations between the length of stay and the following variables: heart rate (p = 0.028), leukocytosis (p = 0.045), neutrophilia (p = 0.033), N/L ratio (p = 0.041) and CRP level (p = 0.003). The N/L ratio was found to have a greater value in regression analysis. It was concluded that there were significant increases in heart rate, leukocytosis, neutrophilia, N/L ratio and CRP levels for the complex cases. There were also positive correlations between the length of stay and the following variables: heart rate, leukocytosis, neutrophilia, N/L ratio and CRP level.

RESUMEN: El propósito de este estudio fue evaluar los cambios en los signos vitales y las pruebas de laboratorio de pacientes con infecciones odontogénicas que requirieron hospitalización, así como verificar su efectividad para determinar la gravedad del caso y las posibles correlaciones con la duración de la internación. Pacientes con infecciones odontogénicas que requirieron hospitalización fueron evaluados prospectivamente entre octubre de 2016 y abril de 2018. Los pacientes se dividieron en dos grupos considerados como casos simples (Grupo 1) o complejos (Grupo 2) según la duración de la internación. Se analizaron los datos personales, comorbilidades, signos y síntomas, signos vitales y pruebas de laboratorio. En este estudio, se detectaron 84 casos de infecciones maxilofaciales y se incluyeron 50 casos de infecciones odontogénicas. Hubo aumentos significativos en la frecuencia cardíaca (p = 0,012), leucocitosis (p = 0,037), neutrofilia (p = 0,021), relación neutrófilos / linfocitos (N/L) (p = 0,044) y niveles de proteína C reactiva (PCR) (p = 0,004) en el Grupo 2. Además, hubo correlaciones positivas entre la duración de la internación y las siguientes variables: frecuencia cardíaca (p = 0,028), leucocitosis (p = 0,045), neutrofilia (p = 0,033), relación N/L (p = 0,041) y nivel de PCR (p = 0,003). Se encontró que la relación N/L tenía un mayor valor en el análisis de regresión. En conclusión, hubo aumentos significativos en la frecuencia cardíaca, leucocitosis, neutrofilia, relación N/L y niveles de PCR para los casos complejos. También hubo correlaciones positivas entre la duración de la internación y las siguientes variables: frecuencia cardíaca, leucocitosis, neutrofilia, relación N/L y nivel de PCR.

Isolated Meningitis and Lacrimal Gland Abscess due to Odontogenic Sinusitis: Case Report / Meningitis Aislada y Absceso de la Glándula Lagrimal debido a Sinusitis Odontogénica: Reporte de un Caso

ABSTRACT: Our objective was report an extremely rare case of isolated meningitis and suppurative dacrioadenitis as consequences of odontogenic sinusitis. We describe the diagnostic tools including imaging and culture, as well as surgical treatment and follow-up. Our final diagnosis was odontogenic sinusitis caused by Streptococcus Anginosus complicated by isolated meningitis and lacrimal gland abscess. Urgent surgical treatment to restore the paranasal sinuses and drainage of the lacrimal gland was performed. Culture from purulent material collected from maxillary sinus indicated the targeted therapy. Clinical assessment and imaging obtained 20 days after surgery demonstrated successful results. This case emphasizes the importance of evaluating intracranial complications of rinosinusitis, the need to search for a dental infection when a maxillary sinusitis is encountered, the key role of a thorough diagnostic workup in order to plan a comprehensive and effective surgical treatment, as well as targeted medical therapy.

RESUMEN: En este estudio se informa un caso extremadamente raro de meningitis aislada y dacrioadenitis supurativa, como consecuencia de sinusitis odontogénica. Describimos las herramientas de diagnóstico que incluyen imágenes y cultivo, como también el tratamiento quirúrgico y el seguimiento. El diagnóstico final fue de sinusitis odontogénica causada por estreptococo anginoso complicado por una meningitis aislada y el absceso de la glándula lagrimal. Se realizó un tratamiento quirúrgico de urgencia para restaurar los senos paranasales y drenar la glándula lagrimal. Se determinó el tratamiento de acuerdo a los resultados de cultivo del seno maxilar. La evaluación clínica y las imágenes obtenidas 20 días después de la cirugía demostraron resultados exitosos. Es importante la evaluación de las complicaciones intracraneales de la rinosinusitis además de la necesidad de considerar una infección dental frente a una sinusitis maxilar. Por otra parte, es clave una evaluación exhaustiva de diagnóstico para planificar un tratamiento quirúrgico completo y efectivo, así como el tratamiento médico.

Infecção cervicofacial grave de origem odontogênica: relato de caso / Severe cervicofacial infection of odontogenic origin: case report

Introdução: as infecções odontogênicas tem como principal origem a necrose pulpar com invasão bacteriana no tecido periapical e periodontal, podendo levar à formação de quadros de celulite e posteriormente de abscesso, além disso, possuem o potencial de disseminar-se pelos espaços faciais profundos e comprometer a vida do paciente. Complicações graves, decorrentes dos quadros de infecções odontogênicas, podem ocorrer, se o tratamento instituído não for adequado, como: trombose do seio cavernoso, abscesso cerebral, mediastinite e até óbito. Objetivo: discutir o manejo das infecções odontogênicas disseminados em espaços faciais profundos, através do relato de caso clínico. Caso clínico: paciente de 52 anos, portador de diabetes mellitus tipo 2, com infecção odontogênica, no exame clínico inicial apresentava trismo, disfonia, dispneia, disfagia, hiperemia e edema em lado esquerdo da face, envolvendo os espaços canino, bucal, submandibular e cervical além de unidades dentárias com foco infeccioso. Em exame de tomográfica computadorizada, observou-se desvio da via área, presença de um grande volume de gás e de lojas de infecção. Optou-se como tratamento a remoção dos focos dentários e drenagem intraoral foi realizada pela equipe da CTBMF com anestesia local e posteriormente drenagem sob anestesia geral, intubação com uso de fibroscopia pela equipe de cirurgia cabeça e pescoço. Considerações finais: as infecções odontogênicas que envolvem espaços faciais profundos devem ser tratadas com urgência e o tratamento de escolha dessa condição deve ser remoção imediata do foco infeccioso, exploração e drenagem rápida e agressiva dos espaços faciais envolvidos e associação com antimicrobianos de amplo espectro com características bactericidas.(AU)

Introduction: the main origin of odontogenic infections is pulp necrosis with bacterial invasion in the periapical and periodontal tissue, which may lead to the formation of cellulitis and later abscess, besides having the potential to spread to the deep facial spaces and compromise the patient's life. Severe complications from dental infections may occur if the treatment is not appropriate, such as cavernous sinus thrombosis, brain abscess, mediastinitis and even death. Objective: to discuss the management of disseminated odontogenic infections in deep facial spaces through a case report. Case report: a 52-year-old patient with type 2 diabetes mellitus, with odontogenic infection, presented at the initial clinical examination trismus, dysphonia, dysphagia, dysphagia, hyperemia and edema on the left side of the face involving the canine, buccal, submandibular and cervical spaces. of dental units with infectious focus. CT scan revealed deviation of the airway, presence of a large volume of gas and infection stores. The treatment was chosen to remove dental foci and intraoral drainage was performed by the CTBMF team under local anesthesia and subsequently under general anesthesia drainage, intubation with fibroscopy by the head and neck surgery team. Final considerations: odontogenic infections involving deep facial spaces should be treated urgently and the treatment of choice for this condition should be immediate removal of the infectious focus, rapid and aggressive exploration and drainage of the involved facial spaces and association with broad-spectrum antimicrobials with bactericidal characteristics.(AU)

Consideraciones para el manejo de un implante inmediato en alvéolos infectados: una actualización / Considerations for the management of an immediate implant in infected sockets: an update

Introducción: La instalación inmediata del implante posterior a la extracción dental se está convirtiendo en un procedimiento de rutina debido a la reducción del tiempo de tratamiento y a la preservación de las estructuras anatómicas remanentes. Sin embargo, en muchos casos esta técnica involucra dientes afectados con procesos infecciosos. Hasta ahora, no se ha descrito a ciencia cierta el grado de éxito o fracaso del implante inmediato en alvéolos infectados, ni se ha establecido un protocolo para el manejo de este tipo de casos. Objetivo: Realizar una revisión bibliográfica actualizada, para determinar qué consideraciones se deben tener para instalar un implante inmediato en alvéolos con procesos infecciosos. Conclusión: Es posible obtener las ventajas de la instalación inmediata del implante en alvéolos infectados mediante la aplicación de un adecuado manejo clínico, donde se considere un adecuado tratamiento antibiótico, acompañado de un correcto curetaje alveolar, respetar la cadena de asepsia y antisepsia, posición subcrestal del implante y obtener siempre una buena estabilidad primaria del implante (AU)

Introduction: The immediate placement of the implant after dental extraction is a procedure that every time is becoming a routine procedure due to the reduction of the treatment time and the preservation of the remaining anatomical structures. However, in many cases, this technique involves affected teeth with infectious processes. Until now, the degree of success or failure of the immediate implant in infected alveoli has not been described for sure; nor has a protocol been established for the management of these types of cases. Objective: Carry out an updated bibliographic review, to determine what considerations must be taken to install an immediate implant in alveoli with infectious processes. Conclusion: Is possible obtain the advantages of the immediate installation of the implant in infected alveoli through the application of adequate clinical management, where appropriate antibiotic treatment is considered, accompanied by proper alveolar curettage, respect the aseptic and antiseptic chain, implant subcrestal position and always obtain a good primary stability of the implant (AU)

Resultados clínicos e imagenológicos en pacientes con rinosinusitis crónica odontogénica / Evaluation of clinical and imaging results in patients with chronic odontogenic rhinosinusitis

INTRODUCCIÓN: La rinosinusitis crónica odontogénica (RSCO) es un proceso inflamatorio/infeccioso de la mucosa nasal y senos paranasales (SPN) de origen dental. Corresponde a una patología subdiagnosticada en la actualidad. El gold standard diagnóstico es la tomografia computarizada. Los tratamientos difieren, desde tratamiento médico aislado hasta médico-quirúrgico de SPN o combinados. OBJETIVO: Caracterizar los resultados clinicos e imagenológicos de pacientes con RSCO en función del tratamiento recibido, para establecer recomendaciones terapéuticas. Describir la frecuencia de subdiagnóstico de esta patología. MATERIAL Y MÉTODO: Estudio descriptivo, retrospectivo. Se incluyeron pacientes con diagnóstico clínico e imagenológico de RSCO entre los años 2013-2017 en un centro de atención médico privado, a los que se realizó una tomografía computarizada cone beam de control. Fueron excluidos aquellos con rinosinusitis crónica, cirugía endoscópica funcional (CEF) previa, cáncer, embarazadas, rechazo a tomografía computarizada cone beam, ausencia de imágenes preoperatorias y menores de 18 años. RESULTADOS: De un total de 27 pacientes, en los operados de CEF (n =24; 89%) la resolución total de los síntomas se logró en 20/24 (83%), resolución parcial 3/24 (12,5%) y persistencia de los síntomas 1/24 (4%). Discusión: De los pacientes con RSCO 22/27 (81%) no tenían reportado el foco dental en el informe radiológico a pesar de ser visible. Aquellos pacientes con sintomatologia postratamiento, hubo factores identificados como la bilateralidad, mala dentadura general, falta de combinación de tratamiento dental y CEF. CONCLUSIONES: La CEF combinada con tratamiento dental concomitante, tiene un alto grado de éxito radiológico y clínico en esta patología. No fue posible demostrar si siempre es requerida la exodoncia con cierre de fístula oro-antral o si se pueden seleccionar pacientes para un tratamiento más conservador.

INTRODUCTION: Chronic odontogenic rhinosinusitis (CORS) is an inflammatory/infectious process of the nasal mucosa and sinuses of dental origin. Actually, it corresponds to an underdiagnosed pathology. The gold standard diagnosis is computed tomography. The treatments differ, from isolated medical treatment to medical-surgical sinuses or combined. AIM: To characterize the clinical and imaging results of patients with CORS according to the treatment received, to establish therapeutic recommendations. In addition to describing the frequency of subdiagnosis of this pathology. MATERIAL AND METHOD: Descriptive, retrospective study. Patients with clinical and imaging diagnosis of CORS between 2013-2017 were included in a private medical care center, to whom a cone beam computed tomography control was performed. Those with chronic rhinosinusitis, previous functional endoscopic sinus surgery (FESS), cancer, pregnant women, rejection of cone beam computed tomography, absence of preoperative images and those under 18 years were excluded. RESULTS: Of all patients operated on FESS (n =24; 89%) the total resolution of the symptoms was 20/24 (83%), partial resolution 3/24 (12.5%) and persistence of the symptoms a 1/24 (4%). Discussion: 22/27 (81%) of patients with CORS had not reported the dental focus in the radiological report despite being visible. Those patients with post-treatment symptoms had identified factors such as bilaterality, general bad teeth, lack of combination of dental treatment and FESS. CONCLUSION: The FESS combined with concomitant dental treatment, has a high degree of radiological and clinical success in this pathology. It was not possible to demonstrate whether exodontia with closure of oroantral fistula is always required or if patients can be selected for a more conservative treatment.
