purpose : to report a rare case of isolated orbital mucocele after trauma case report : a 45-year-old man presented with swelling in the left orbital region. the only significant event in his medical history was trauma which occurred 25 years previously during the iran-iraq war. computed tomography revealed a left medial intraorbital cystic mass lesion. the cystic mass was completely removed th...

OBJECTIVE To clarify the three-dimensional anatomical features of the sphenoid sinus and its surrounding structures as are relevant to performing an endoscopic sphenoidotomy. METHODS Various dimensions of 224 CT images of the sphenoid sinus and surrounding structures from 122 Japanese adult patients were measured using the multiplanar reconstruction technique. RESULTS The mean distance from...

Background Sphenoethmoid cells may be above the sphenoid sinus with/ or without con-tact to optical nerve. Although sphenoethmoid cells are theoretically considered to possibly influence the sphenoid sinus volume, we could not find any study in the literature on this issue. Aims The aim of our study was to detect sphenoethmoid cells and measure the sphenoid sinus vol-ume using multiplanar com...

Objectives: Cholesterol granuloma of the sphenoid sinus has rarely been reported. Methods: A 50-year-old man visited our hospital presenting with a 2-year history of intermittent right-sided headache, 1-month history of right-sided tinnitus, and 5-year history of nasal obstruction and purulent nasal discharge. Computed tomography revealed a well-demarcated expansile mass in the right sphenoid s...

conclusions surgeons should consider the possibility of existence of other mucoceles when they find a large downstream sinus mucocele obstructing the ostia of upstream sinuses on computed tomography scans. introduction mucoceles of the paranasal sinuses are relatively rare. a very busy otolaryngology department does not have more than a few cases each year. bilateral, multiple, and multiloculat...

OBJECTIVE To compare frontal sinus cranialization to obliteration for future prevention of secondary mucocele formation following open surgery for benign lesions of the frontal sinus. STUDY DESIGN Retrospective case series. SETTING Tertiary academic medical center. PATIENTS Sixty-nine patients operated for benign frontal sinus pathology between 1994 and 2011. INTERVENTIONS Open excision...

OBJECTIVE The purpose of this study was to determine changes in the surgical treatment of patients with the diagnosis of paranasal mucoceles managed in a Latin American hospital. We hypothesised that endonasal endoscopic surgeries had emerged as the main treatment option for this disease in the last five years. METHODS A retrospective chart review of all patients who were diagnosed with paran...
