    Journal: Int J Surg Case Rep; 2021 Dec; 89():106594. PubMed ID: 34794074.
    Abstract:
    BACKGROUND: Cerebrospinal fluid (CSF) leak that occurred in the lateral sphenoid sinus is a rare and difficult case. This paper aims to report a case of defect closure in the lateral recess of the sphenoid sinus endoscopically with a transpterygoid approach. CASE PRESENTATION: A 38-year-old Indonesian woman reported a CSF leak, and identified a defect in the lateral recess of the left sphenoid sinus. CSF leak was repaired with endoscopic transethmoid-pterygoid or transpterygoid endoscopic surgery and no CSF leak was found. The surgical procedure was successful even though it was only performed by an otorhinolaryngologist. DISCUSSION: Endoscopic transethmoid-pterygoid or transpterygoid endoscopic surgery is effective in repairing defects in the lateral recess of the sphenoid sinus in which surgical procedure is performed by a single otorhinolaryngologist. CONCLUSION: Endoscopic transpterygoid approach gained access to lateral site of sphenoid sinus was an effective approach in managing CSF leak of lateral sphenoid recess. Closure of the defect using a bone graft and mucosa of the middle turbinate was proven to be effective. It had been carried out successfully in Indonesia.
