INTRODUCCIÓN: La enfermedad aislada del seno esfenoidal es rara y representa el 1-2% de todas las patologías inflamatorias sinusales y < 0,05% de las lesiones malignas sinusales. Es difícil establecer el diagnóstico debido a la presentación clínica inespecífica. La cefalea frontal y/o retroocular es la principal manifestación. El retraso en el diagnóstico y tratamiento puede resultar en serias complicaciones debido a sus relaciones anatómicas. OBJETIVOS: Presentar nuestra experiencia en lesiones esfenoidales aisladas, analizando sintomatología, etiología, diagnóstico y tratamiento de las mismas...
INTRODUCTION: Isolated sphenoid sinus disease is rare and accounts for1-2% of all inflammatory sinus pathologies and <0.05% of malignant sinus lesions. It is difficult to establish the diagnosis due to its nonspecific clinical presentation. Frontal and/or retro-ocular headache is the main symptom. Delay in diagnosis and treatment can result in major complications due to their anatomical relationships. OBJECTIVE: Present our experience in isolated sphenoid injuries, through the analysis of symptomatology, etiology, diagnosis and treatment of them...

El mucocele es un tumor pseudoquístico poco frecuente en el seno maxilar y una rara complicación de la cirugía ortognática. El caso reportado describe la presentación de un mucocele que afecta parcialmente el seno maxilar y se presenta clínicamente como un tumor nasal. Se trata de una mujer de 44 años que, luego de 12 años de realizarse cirugías ortognáticas, presenta dolor facial y obstrucción de la fosa nasal derecha. La tomografía axial computarizada de senos paranasales revela una masa de contenido líquido que ocupa la mitad inferior del seno maxilar derecho, extendiéndose a la fosa nasal ipsilateral. La paciente es intervenida por vía endoscópica realizándose una marsupialización intranasal y meatotomía media, evolucionando satisfactoriamente en un seguimiento de dos años.
Mucoceles are not often found in the maxillary sinus, and is a rare surgery complication, in this case, orthognathic. This review describes a mucocele that partially occupies the right maxillary sinus, causing a chronic nasal obstruction. This is the case of a 44 year-old female patient, which after 12 years of several orthognathic surgeries, presents facial pain and right nasal obstruction. The paranasal sinus computed tomography reveals a mass with liquid content that occupies the lower part of the right maxillary sinus and compromises the right nasal cavity. The patient was treated with an intranasal marsupialization and a middle meatotomy with endoscopic nasal approach. Evolution was satisfactory two years after the intervention.

ABSTRACT INTRODUCTION: The proximity of the roots to the maxillary sinus can create a variety of risks. OBJECTIVE: To evaluate the relationship between the roots of healthy teeth and the maxillary sinus, as well as the occurrence of sinus pathologies. METHODS: Three radiologists analyzed 109 cone beam computed tomography (CBCT) images. The Kappa test was used to assess the intra- and inter-rater agreement. The chi-squared test and prevalence ratio were used to test the hypothesis that roots of healthy teeth in the maxillary sinus favored the occurrence of sinus pathologies ( p = 0.01). RESULTS: Intra- and inter-rater agreement ranged from good to excellent. The chi-squared test demonstrated a statistically significant difference ( p = 0.006) between the tooth roots in diseased maxillary sinuses (6.09%) and those in normal sinuses (3.43%). The prevalence ratio test showed a statistically significant higher prevalence of tooth roots in diseased sinuses than in normal sinuses ( p < 0.0001). Roots in the maxillary sinus were 1.82 times more associated with diseased sinuses. CONCLUSION: Dental roots in the maxillary sinus are almost twice as likely to be associated with diseased sinuses than normal sinuses. Healthy teeth whose roots are inside the maxillary sinus may induce an inflammatory response in the sinus membrane. It is suspected that dental procedures may exacerbate the condition.
RESUMO INTRODUÇÃO: A proximidade das raízes com o seio maxilar pode criar uma variedade de riscos. OBJETIVO: Avaliar a relação entre as raízes dos dentes hígidos com o seio maxilar, assim como com a ocorrência de doenças sinusais. MÉTODO: Três radiologistas analisaram 109 imagens de tomografia computadorizada de feixe cônico (TCFC). O teste Kappa avaliou a concordância intra e interexaminadores. Os testes de Qui-quadrado e Razão de Prevalência foram utilizados para testar a hipótese de que raízes de dentes hígidos dentro do seio maxilar favorecem a ocorrência doenças sinusais (nível de significância = 0,01). RESULTADOS: A concordância intra e interexaminadores variou de boa a excelente. O teste Qui-quadrado mostrou uma diferença estatisticamente significante (p = 0,006) entre as raízes dentárias dentro do seio maxilar patológico (6,09%) e aquelas dentro do seio normal (3,43%). O teste de Razão de Prevalência mostrou uma ocorrência de raízes dentárias dentro de seios patológicos estatisticamente maior do que dentro de seios normais (p < 0,0001). As raízes dentro do seio maxilar foram encontradas 1,82 vezes mais associadas a seios patológicos. CONCLUSÃO: Raízes dentárias dentro do seio maxilar são quase duas vezes mais associadas a seios patológicos do que a seios normais. Dentes hígidos que têm raízes dentro do seio maxilar podem induzir uma resposta inflamatória da mucosa sinusal. Suspeita-se que procedimentos odontológicos possam agravar tal situação.

The sphenoidal sinus mucocele is a pseudocystic lesion of paranasal cavity (CPN). These injuries are probably underdiagnosed as they may be asymptomatic or cause nonspecific symptoms. The CT scan and the MRI increase the precision of the preoperative evaluation. We present a case of sphenoid sinus mucocele in a patient of 69 years old, who was admitted at our institution with 1 month evolution of persistent headache. Clinical presentation, diagnosis and treatment of this case are discussed as well as the review of the literature...

Se presentan dos casos clínicos del Servicio de Otorrinolaringología (SORL) del Hospital Barros Luco Trudeau (HBLT) con diagnóstico de Pneumosinus dilatans (PD). El PD es una rara condición, que se presenta como una dilatación anormal de uno o varios senos paranasales (SP) sin evidencia de compromiso óseo ni mucoso, que se asocia a dolor y deformidad facial. La tomografía computada (TC) permite hacer el diagnóstico; el tratamiento es quirúrgico y está orientado a descomprimir el o los SP comprometidos; con lo anterior se logra la erradicación del dolor, pero la deformidad facial persiste.
Two clinical cases with a diagnosis of pneumosinus dilatans (PD) from the Servicio de Otorrinolaringología (SORL) of Hospital Barros Lucos-Trudeau (HBLT) are presented. PD is a rare condition in which an abnormal enlargement of one or several paranasal sinuses (PS) is present, with no evidence of bone or mucosa involvement. It is associated with facial pain and deformity. Diagnosis is based on CT scan; treatment is surgical and it is oriented to decompress the PS involved, eradicating pain but with a persisting facial deformity.

The aim of this study was to find out the pattern of extracranial complications of CSOM cases who attended to the department of ENTD, Mymensingh Medical College Hospital during the period from July'1999 to June' 2001. Different types of extracranial complications of CSOM were presented here. A total of 100 cases, diagnosed clinically and radiologically were included in the study of which 66 were male and 34 were female giving a male to female ratio of 1.94 : 1 (p < 0.05). Majority cases (53) were in the age group of 11- 20 years followed by the age group of below 10 years where there were 30 cases. Majority (64) cases came from low socio-economic class. The number of different types of extracranial complications of CSOM were as follows: mastoid abscess 57, discharging sinuses 28, purulent labyrinthitis 07, Bezold's abscess 04, fascial nerve paralysis 03 and zygomatic abscess 01. In all cases of CSOM Cholesteatoma were detected. In 14 cases, Cholesteatoma were associated with granulation tissue/polyp. Modified radical mastoidectomy were performed in all cases. On analyzing the findings of the present study it was observed that mastoid abscess were the predominant extracranial complications of CSOM, affecting mostly the male population of 11 - 20 years age group coming from low socio-economic class.

O diagnóstico das doenças dos seios paranasais tem sido elucidado mais claramente nos últimos anos com a juda da endoscopia nasal e tomografia computadorizada. O objetivo dos autores é chamar a atençäo para a importância do diagnóstico causal de origem rinogênica nos pacientes portadores de sinisites de repetiçäo. A necessidade do tratamento da causa básica nesses casos é indiscutível, evitando-se assim a instalaçäo de processos sinusais crônicos e suas complicaçöes
