Outcomes of Endoscopic Sinus Surgery in Treating Paranasal Sinus Mucoceles with Orbital Complications

Objective: Mucoceles, benign cystic lesions within the paranasal sinuses, often progress slowly, leading to bone erosion and potential orbital complications such as subperiosteal abscesses, posing severe intracranial risks. This study investigates the effectiveness of endoscopic sinus surgery in managing mucoceles accompanied by orbital complications.

Methods: We conducted a retrospective analysis of 68 patients diagnosed with paranasal sinus mucoceles, focusing on mucocele location, associated orbital complications (manifesting as ophthalmic symptoms and optic neuropathy), onset timing, surgical interventions, and visual outcomes. Data were collected from patients treated at the Ear Nose Throat Ho Chi Minh City hospital.

Results: Among 68 patients, 76 mucoceles were identified with orbital complications. Notably, 28.9% were secondary mucoceles post-prior surgeries, 21.1% linked to previous facial trauma, and 50% primary mucoceles. Predominant mucocele locations included the frontal ethmoid region (47.4%), frontal sinus (10.5%), ethmoid sinus (13.2%), maxillary sinus (17.1%), maxillary-ethmoidal sinus (6.6%), and sphenoid sinus (5.3%). Clinical symptoms included bulging eyes (48.5%), double vision (16.2%), reduced vision (13.2%), and limited eye movement (11.8%). Most cas (93.4%) underwent endoscopic sinus surgery, with 6.6% requiring a combined approach.

Conclusion: Early identification of mucoceles and associated complications, especially those affecting ocular health, is vital. Raising awareness among medical professionals about paranasal sinus mucoceles is crucial for prompt diagnosis and intervention. Endoscopic sinus surgery proves effective in managing both simple and complex mucoceles, offering promising outcomes for patients.
