摘要

In 7.7% cases of spontaneous cerebrospinal fluid (CSF) rhinorrhea, the site of leak is lateral recess of sphenoid sinus (LRS). There is paucity of studies comparing LRS leaks and demographics in general, and BMI in particular. This study aims to evaluate the clinicoradiological characteristics, treatment and outcomes of these patients. In this retrospective review of electronic medical records and imaging (Magnetic Resonance Imaging (MRI) and Computed Tomography (CT) scan of the nose and paranasal sinuses) conducted at the department of ENT at a tertiary care center in South India, all data regarding demography, symptomatology, radiological features, operative findings, treatment, outcome, and postoperative complications were recorded. All patients diagnosed with sphenoid sinus CSF leak from 2010 to 2021 were included. Among the 11 patients with 12 sites of leak, the average BMI was 24.45, with a normal BMI in five patients. Of the ten patients with spontaneous CSF rhinorrhea, 60% were female. The most common comorbidity was hypertension, particularly in women. Ten patients had unilateral leaks, 60% of which were on the left side. All patients had empty sella on MRI, with the majority showing grade 4 empty sella. Intraoperatively, meningoceles were present in 72.73% of patients, with half having concomitant encephaloceles. All patients were managed endoscopically. Spontaneous CSF leaks in sphenoid sinus tend to be unilateral, more common on the left side, and involve the lateral recess. Contrary to previous studies, there was no significant gender predominance or association with obesity in this cohort.
