Paranasal Sinus Mucoceles with Intraorbital Extension
Objectives: The aim of this study was to report the clinical features, management, and outcome of patients with paranasal sinus
mucocele with intraorbital extension.
Materials and Methods: Eleven patients who were diagnosed and treated for paranasal sinus mucocele with intraorbital extension
between 2005-2012 were included in this retrospective study. The clinical characteristics, treatment modalities, and complications were
recorded and analyzed.
Results: The records of 11 patients (aged 25 to 69, mean 47.6±15.6 years) with orbital mucocele were included in this study. The most
frequent initial symptoms and findings were proptosis in 7 patients (63.6%), diplopia in 6 patients (54.5%), and ocular movement
limitation in 6 patients (54.5%). The origin of the orbital mucocele was frontal sinus in 6 patients (54.5%), ethmoidal sinus in
3 patients (27.3%), and maxillary sinus in 2 patients (18.2%). Eight patients whose mucoceles were approachable with endoscopy
(72.7%) were treated with functional endoscopic sinus surgery (ESS) and marsupialization of the sinus to the nasal cavity. Three patients’
mucoceles (27.3%) were located in the lateral side of the frontal sinus and were unapproachable with endoscopy. In these patients, the
endoscopic approach was combined with the osteoplastic flap technique by external approach. After surgery, all the patients’ findings and
symptoms improved; only one patient who had recurrent bilateral mucoceles required additional surgery. This recurrence was regressed
by endoscopic surgery and no additional complications were observed.
Conclusion: The frontal and ethmoidal sinuses were the most common origin of orbital mucoceles. Proptosis, limitation of eye
movements, and diplopia were the most frequently detected signs in patients with orbital mucocele. Endoscopic sinus surgery produced
favorable results in patients with an endoscopically approachable mucocele, and the osteoplastic flap technique with external approach
led to successful results in patients with endoscopically unapproachable mucoceles. (Turk J Ophthalmol 2014; 44: 297-300
