Craniofacial Pain Locations and Outcomes After Endoscopic Sinus Surgery for Unilateral Sphenoid Sinusitis: A Multi-Institutional Study

Unilateral sphenoid sinus opacification on computed tomography is caused by a variety of pathologies including inflammatory and infectious sinusitis, benign and malignant tumors, and encephaloceles. The purpose of this study was to report craniofacial pain locations and outcomes in inflammatory unilateral sphenoid sinusitis (USS) patients who underwent endoscopic sinus surgery (ESS). A multi-institutional retrospective cohort study was conducted on all adult patients who had ESS for USS from 2015 to 2022. Patient demographics, presenting symptoms and nasal endoscopy findings, extent of surgical dissection, and craniofacial pain locations and outcomes were recorded. Exclusion criteria included age 0.05). In USS patients, the most common craniofacial pain locations were retrobulbar, occipital, and frontal, with a minority being vertex. Based on short-term follow-up, ESS resolved the craniofacial pain in 75% of cases. There were no clinical variables that predicted the presence or resolution of craniofacial pain.
