Rinosinusitis micótica alérgica con destrucción de base de cráneo / Allergic fungal rhinosinusitis with skull base destruction

La sinusitis micótica alérgica es una enfermedad inflamatoria de la mucosa rinosinusal producida por hongos que pueden aislarse de la cavidad de nasal de individuos sanos. Se produce indirectamente por los hongos que actúan como antígeno y desencadenan una reacción inmunológica mediada por IgE que origina pólipos y una secreción mucosa espesa con detritus e hifas denominada mucina. Su presentación clínica más frecuente es una sinusitis crónica unilateral o bilateral con pólipos. Con menos frecuencia, las sustancias originadas por la desgranulación de los eosinófilos producen remodelación o destrucción ósea y la sinusitis puede simular una neoplasia. Se describe el caso clínico de un paciente que padeció una sinusitis micótica alérgica con destrucción ósea masiva de la base del cráneo y que tuvo extensión intracraneal extradural e intraorbitaria de la enfermedad. Fue tratado con éxito mediante cirugía y corticoides. (AU)

Allergic fungal sinusitis is an inflammatory disease of the rhinosinusal mucosa caused by fungi that can be isolated from the nasal cavity of healthy individuals. The pathology is produced indirectly by the fungus that acts as an antigen and triggers an IgE-mediated allergic reaction that causes polyps and a thick mucous discharge with detritus and hyphae called mucin. Its most common clinical presentation is unilateral or bilateral chronic sinusitis with polyps. Less commonly, substances originated by the degranulation of eosinophils cause bone remodeling or destruction, and sinusitis can simulate a neoplasia. We describe the clinical case of a patient who suffered from allergic fungal sinusitis with massive bone destruction of the skull base and who had intracranial, extradural and intraorbital extension of the disease. He was successfully treated with surgery and corticosteroids.Key words: allergic fungal sinusitis, intracranial extension, endoscopic surgery, transorbital transpalpebral approach. (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.

ABSTRACT Introduction: Endoscopic sinus surgery (ESS) is a technique widely used in otorhinolaryngology. The differences in pediatric population should be considered, compared to adults. Aim: To describe and analyze the clinical characteristics, epidemiology and surgical results of ESS in pediatric population. Material and method: Retrospective and descriptive study of all pediatric patients who underwent ESS for the treatment of any otorhinolaryngological pathology, between 2012 and 2017. Variables analyzed include demographics, signs and symptoms, surgical complications and recurrence rate. Results: The series includes 19 patients, with a mean age of 10 years at the moment of surgery; 10 men and 9 women. Antrochoanal polyp (AP) was the main diagnosis, followed by chronic rhinosinusitis. On follow-up, 4 patients presented with a recurrence at a mean period of 36 months. No surgical complications were observed. Conclusion: The study of pediatric patients includes anamnesis, physical examination and images in order to define the indication of SES. In those cases, properly selected, CENS results a safe and effective procedure.

Anatomical Variations of the Middle Turbinate Concha Bullosa and its Relationship with Chronic Sinusitis: A Prospective Radiologic Study

Abstract Introduction A pneumatized turbinate, also called concha bullosa, is a normal anatomical variant of the paranasal sinus region. Depending on the site of pneumatization, the concha is classified into extensive, bulbous or lamellar type. The middle turbinate concha bullosa has been implicated as a possible etiological factor in chronic sinusitis. Objectives The aim of this study was to investigate the anatomical variations of the concha bullosa, based on paranasal sinus imaging, and its possible association with sinusitis. Methods This prospective descriptive study was performed at the Department of ENT and Head Neck Surgery over a period of one year, from 2016 to 2017. We studied the computed tomography scans of the nose and paranasal sinuses- in axial, coronal and sagittal planes-of patients who had symptoms of nasal obstruction, or headache and features of chronic sinusitis. Results Out of the 202 scans studied, the prevalence of concha bullosa was 31.7%. The concha was bilateral in 35 (54.7%) patients and unilateral in 29 (45.3%) patients. Out of 99 conchae, 54 were on the right side and 45 were on left side. Ipsilateral sinusitiswas found in 40.4% of the sides in the scans of subjectswith concha. There was no statistically significant association between any type of middle turbinate concha with sinusitis, but sinusitis was more predominant with the extensive type of concha (p > 0.05). Conclusion Multiple air cells, mucocele, pyocele and inflammatory mucosal thickenings in the concha are relatively rare. Detailed knowledge of anatomic variations of the concha bullosa is imperative for the radiologists and the operating surgeons.

Abscesso subperiosteal com extensão epidural devido à rinossinusite aguda em criança de dez anos / Subperiosteal abscess with epidural extension due to acute rhinosinusitis in a ten-year-old child

RESUMO A rinossinusite aguda é uma das afecções mais prevalentes das vias aéreas superiores. Fatores anatômicos presentes em crianças e jovens propiciam o aparecimento de complicações orbitárias. Embora mais raras, as complicações intracranianas das rinossinusites perfazem um grau alto de letalidade, são mais comuns em pacientes acima de sete anos, e devem ser tratadas por uma equipe multidisciplinar.

ABSTRACT Acute rhinosinusitis is one of the most prevalent diseases of the upper airways. Anatomical factors present in children and young people allow for the onset of orbital complications. Although rare, intracranial complications of sinusitis account for a high degree of lethality, are more common in patients over the age of seven, and should be treated by a multidisciplinary team.

The Imaging Appearance of Sinus Mycetoma: A Case Series / El Aspecto Imagenológico del Micetoma Sinusal: Serie de Casos

Sinus mycetoma is a dense accumulation of hyphae that form a rounded mass within the mucosal confines of a paranasal sinus. The aim of this study was to present a case series of three patients with maxillary sinus mycetoma and to describe their radiographic presentations. Three cases are presented. The first two, a 44-year-old woman and an 88 year-old man, both diabetics, were referred to maxillofacial treatment by other specialties. They both had a bad odor of unknown origin on the facial level and their respective computerized tomographies revealed a unilateral opacification of the maxillary sinus with a region of greater radio-opacity. The third case is a 31-year-old woman with a history of a severe facial trauma who had undergone surgery and for whom orthognathic surgery had been planned to correct side effects. In addition to the orthognathic surgery, the removal of the lesion that appeared opacified in the pre-surgery scan was planned. She showed opacification of the maxillary sinus and during the intraoperative stage, tissue of a whitish-gray appearance was detected on the maxillary sinus. The lesion was completely removed and the result of the histopathological study was sinus mycetoma. The patients evolved favorably and the symptomatology disappeared completely. The growing occurrence of mycetoma and the lack of information on it make publicizing this pathology fundamental so it can be considered as a differential imaging, clinical, and pathological diagnosis and in that way receive adequate and opportune treatment.

El micetoma sinusal es una patología de origen fúngico, que afecta a pacientes inmunocomprometidos, capaz de desorientar en su diagnóstico por su clínica y expresión imagenológica particular. El objetivo de este estudio es presentar una serie de tres casos con micetoma en el seno maxilar y describir su presentación imagenológica. Se presentan tres casos. Los dos primeros, una mujer de 44 años y un hombre de 88 años, ambos diabéticos y derivados a atención maxilofacial por otras especialidades. Coincidía un mal olor expelido de origen desconocido a nivel facial y en sus respectivas tomografías computarizadas se observó velamiento unilateral del seno maxilar con una zona de mayor hiperdensidad. El tercer caso corresponde a una mujer de 31 años con antecedente de trauma facial severo operado, a la cual se le planificó cirugía ortognática para corregir secuelas. En conjunto con la cirugía ortognática, se planificó la biopsia excisional de una lesión hiperdensa que se presentó en el escáner pre-quirúrgico; en el intraoperatorio se pesquisó tejido de aspecto blanquecino grisáceo en el seno maxilar. A todos los pacientes se les realizó la exéresis total de la lesión y el estudio histopatológico dio como resultado micetoma sinusal. Los pacientes evolucionaron favorablemente, desapareciendo por completo la sintomatología. La creciente incidencia del micetoma y el desconocimiento sobre el mismo hacen que sea fundamental la difusión de esta patología para ser considerada como diagnóstico diferencial clínico y patológico, y realizar así un tratamiento adecuado y oportuno.

Digital Tomosynthesis for PNS Evaluation: Comparisons of Patient Exposure and Image Quality with Plain Radiography

OBJECTIVE: We investigated low dose digital tomosynthesis (DT) for the evaluation of the paranasal sinus (PNS), and compared its diagnostic accuracy with a PNS radiography series (XR). MATERIALS AND METHODS: We enrolled 43 patients for whom XR, PNS DT, and OMU CT were performed. We measured effective doses (EDs) of XR, DT, and OMU CT using Monte Carlo simulation software. Two radiologists performed independent observation of both XR and DT. For seven PNSs, they scored anatomic conspicuity of sinuses and confidence on the presence of sinusitis using nine point scales. OMU CT was observed by the third radiologist and the findings were regarded as reference standard. We compared scores for conspicuity and sinusitis confidence between XR and DT. RESULTS: Mean EDs were 29 +/- 6 microSv, 48 +/- 10 microSv, and 980 +/- 250 microSv, respectively, for XR, DT, and CT. Mean scores for conspicuity were 6.3 and 7.4, respectively, for XR and DT. Sensitivity per patient basis for sinusitis detection were 52% and 96%, respectively, for XR and DT in observer 1 (p = 0.001) and 80% and 92% for observer 2 (p = 0.25). Specificities for sinusitis exclusion were 100% for both XR and DT for observer 1 and 89% and 100% for observer 2 (p = 0.50). Accuracies for sinusitis diagnosis were 72% and 98%, respectively, for XR and DT for observer 1 (p = 0.001) and 84% and 95% for observer 2 (p = 0.125). CONCLUSION: Patient radiation dose from low dose DT is comparable with that of PNS XR. Diagnostic sensitivity of DT for sinusitis was superior to PNS XR.

Correlation of X rays and computed tomography in paranasal sinus diseases

Objective of the study was to evaluate the diagnostic yield of X-rays taking CT scan as gold standard in acute and chronic sinusitis. Validation study. The study was conducted in the Radiology Department CMH Rawalpindi, from 1[st] Aug 2007 to 31[st] July 2008. This study involved 95 patients of both genders above 18 years of age who presented with acute and chronic sinusitis in ENT department of CMH Rawalpindi. Patients were referred to Radiology department for their X-ray paranasal sinuses [PNS] and findings were correlated with CT scan. Out of 43 patients clinically suspected of having acute sinusitis, x ray PNS shows imaging findings of acute sinusitis in 26 [60%] patients while 17 patients were having normal x-ray PNS. When CT scan was performed to correlate the findings, it showed 30 [69%] patients were having acute sinusitis while 13 [30%] patients had no imaging findings of sinusitis. Out of 48 patients, x ray PNS showed chronic sinusitis in 26 [54%] patients and 22 patients were having normal x ray PNS. While CT scan showed 33 [68%] patients were having chronic sinusitis and 15 patients were normal. Four patients either didn't reported for their CT scan or they refused to get their CT scan done. Plain radiographs were once the mainstay of diagnosis of sinus disease and now have been replaced by high-resolution CT scan for the evaluation of acute and chronic sinusitis. Plain radiographs do not allow adequate evaluation of the osteomeatal complex or the sphenoid and ethmoid sinuses because of overlapping anatomic structures. CT is the modality of choice for imaging acute and chronic sinusitis and provides the surgeon with important information of the osteomeatal complex and normal variations, preoperatively

Computed tomography scan of rhinosinusitis, current practice, and requirements for endoscopic surgery of paranasal sinuses

To evaluate the current practice in requesting and performing paranasal sinuses CT scan for patients scheduled for endoscopic sinus surgery, and to describe the current hospital's practice in performing these scans. This cross-sectional questionnaire study was conducted in the King Hussein Medical Center, Amman, Jordan between April and May 2010. Three forms were designed to collect data from our study groups, which included: Ear, Nose and Throat [ENT] surgeons, radiologists, and the radiology sections in 3 hospitals. The first was designed for ENT surgeons and aimed at investigating, whether or not they perform endoscopic sinus surgery, and if they have specific requirements for a CT scan of the sinuses. The second was designed for the radiologist to investigate their specifications in performing CT of the sinuses. The last was designed to evaluate the current practice of performing CT of the sinuses at the 3 hospitals. Twenty-four ENT surgeons participated, 83.3% surgeons performed endoscopic sinus surgery, and 83.3% requested specific specifications for the sinuses CT scan, and the most requested specification was coronal plane in 42%. Of the 24 radiologists, 71% prefer the prone position, 71% prefer the coronal plane, and 71% preferred direct coronal. In all 3 hospitals, the axial plane with reconstructed coronal images, the current practice with a slice thickness of 2-3 mm, and the total number of images was 40-50. Differences between ENT surgeons, radiologists, and hospital's practice and other hospitals guidelines found in literature are present. Therefore, we are in need of an agreed upon guideline protocol to obtain the best data with the least radiation dose

Effect of deviated nasal septum on radiological staging of chronic sinus disease using Lund and Mackay radiological grading system

The role of deviated nasal septum in chronic sinusitis is not clearly defined in the literature. The aim of this retrospective study was to identify any significant correlation between the existence of deviated nasal septum and radiological staging of chronic sinusitis in which 40 CT scans done previously for chronic sinusitis patients were included. For every scan, both sides were evaluated separately. For each side a numerical value was obtained for radiological score and a deviated septal score. Statistical evaluation revealed no significan correlation between septal scores and radiological scores of sinusitis [r = 0.06 P>0.05]. using Mann whitney test, there was also no significant difference between radiological sinusitis scores in the group with deviated septum compared to that in the group without deviated septum [p>0.05]

Radiology, ultrasound and endoscopy in the diagnosis of chronic sinusitis

This study was directed to evaluate the ultrasonographic examination of the paranasal sinuses, compared with conventional plain radiography after confirming the diagnosis endoscopically. Computerized tomography was the standard diagnostic tool. The study comprised 20 patients [13 males and 7 females], attending the Ear, Nose and Throat Department of Assiut University Hospital. The majority of the patients were in the 2nd decade of life. The most common symptoms were post nasal discharge, nasal obstruction and headache. Conventional radiographic study was more sensitive than ultrasonography in disease detection [88.88% versus 65.59%], while ultrasound [US] and endoscopy were nearly of the same sensitivity. Ultrasound was found to have higher specificity value in the detection of mucosal thickening and polyp formation, but less specific for fluid level detection. Ultrasonography may be considered as a specific diagnostic tool of the sinusitis

CT scanning in chronic rhinosinusitis. Indications, technique and merits

One hundred patients diagnosed to have chronic rhinosinusitis on clinical and endoscopic basis were examined radiologically by CT scanning of their paranasal sinuses prior to endoscopic sinus surgery. They patients included 51 males and 49 females, their ages ranged between 19 and 66 years. The anterior ethmoidal sinuses including the ethmoidal infundibulum and the ostiomeatal complex were involved in all cases. These findings supported the concept that the anterior ethmoids are the key area in the genesis, persistence and recurrence of disease in the other group of sinuses. CT revealed mucosal changes deep in the ostiomeatal complex that are not visible endoscopically, besides the extent and nature of pathology and the effects of previous sinus surgery can be properly assessed. The merits of CT scanning over other radiological modalities in chronic rhinosinusitis were discussed as well as the proper selection of patients and the modifications in scanning techniques aiming to reduce the cost effectiveness of the examination

Diagnostic and Therapeutic Significance of Sinoscopy in Maxillary Sinusitis

Sinoscopy as an endoscopic investigative method of examining the maxillary sinus offers the advantage of a direct local interpretation in contrast to the usual indirect methods. The beginning of sinoscopy dates back to Hirschmann (1903) and Spielberg (1922). During the last 20 years, this method has been reintroduced and refined. In spite of a large number of articles about sinoscopy from Europe, there have been no articles about sinoscopy from Korea. In the present study, 182 maxillary sinuses were examined by sinoscopy and PNS Xpray for diagnostic reasons. The failure rate in sinoscopy was 3.8% and the rate of incomplete sinoscopy was inferior to X-ray. The detection rate of antral secretion by sinoscopy was higher than by Xpray. In the bacteriological study of antral secretions the percentage of no-growth specimens was 75.7%. In all approximately ten strains of bacteria were isolated from the secretions. Among them, streptococcus was the most common organism found. Therapeutic sinoscopy was performed in 16 patients who suffered from subacute or chronic maxillary sinusitis. In 8 of these patients, local treatment during therapeutic sinoscopy improved the mucosal appearance.
