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...

PURPOSE We used MR imaging to analyze retrospectively the pattern of hyperostosis occurring concomitantly with recurrent sphenoid wing meningiomas. METHODS Bone involvement was compared in 12 corresponding CT and MR studies of 10 female patients with sphenoid wing meningiomas recurrence after earlier surgical treatment. Four of these had histologically confirmed meningiomatous infiltration of...

OBJECTIVE To review and report diseases of the sphenoid sinus from the literature and from a university hospital. METHODS Inpatients' data were retrospectively gathered and reviewed from January 2006 to June 2016. Clinical data, imaging, organisms, and pathological reports were collected. Pathology was divided into infection/inflammation, tumor, and miscellaneous. A literature review was perf...

We aimed to determine the position, number and variability of the sphenoid sinus ostia. A total of 32 dry skulls were examined under x6 magnification. The septum and nasal turbinates were removed to expose the anterior wall of the sphenoid sinus. A caliper was used for measurements. We found 2 ostia per skull, except for one (3%), in which the left ostium was absent. The inferior edges of both ...

We report on a 28-year-old man with severe headache. Imaging studies included CT and MR. A large sphenoid mucocoele was demonstrated as well as findings compatible with fibrous dysplasia of the facial bones. Both disorders had been previously unknown. Imaging findings suggested that the sphenoid mucocoele was related to an obstruction caused by the expansile bone of fibrous dysplasia. These fin...

OBJECTIVE The aim of this study was to evaluate the frequency of anatomical variation in nasal cavity and paranasal sinuses by comparing a unilateral cleft lip and palate (UCLP) group with a non-syndromic control group using cone beam computed tomography (CBCT). SUBJECTS AND METHODS This study included 24 UCLP patients in the UCLP group and 24 non-syndromic patients in the control group. Coro...

A 55-year-old man initially presented with progressive right-sided vision loss during hospitalization following revision liver transplant. He underwent treatment with high-dose corticosteroids for presumed optic neuritis, with initial vision improvement that subsequently progressed to complete visual loss. He was then transferred to our facility. Repeat radiographic analysis demonstrated left m...

BACKGROUND The surgical management of chronic recurrent sinusitis (CRS) recalcitrant to medical therapy in the pediatric population has traditionally consisted of adenoidectomy and functional endoscopic sinus surgery (FESS), depending on age and imaging findings. Adenoidectomy relieves nasopharyngeal airway obstruction as well as potentially eradicates a bacterial reservoir. FESS, as in adults,...

BACKGROUND Unilateral isolated sphenoid sinus disease (ISSD) is a rare diagnosis of the paranasal sinuses that can be associated with complications involving vascular, neurologic, and optic structures in close proximity. CASE PRESENTATION A 62 year old female presented to a hospital in Georgetown, Guyana with right lateral rectus palsy, diplopia, and a severe progressively worsening headache....

BACKGROUND Spontaneous cerebrospinal fluid leaks are rare but may lead to confusion with other diseases in patients without history of trauma. We report a rare case unusual for two reasons. First, our patient was put under antiallergic medication for months before the diagnosis of spontaneous cerebrospinal fluid leak of the sphenoid sinus. Second, our patient was managed successfully by a ventr...
