Abstract

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 second-
ary 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%), maxil-
lary 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 diag-
nosis and intervention. Endoscopic sinus surgery proves effective in managing both simple and complex mucoceles,
offering promising outcomes for patients.
