The Relationship Between Destruction Sites and Clinical Findings in Diffuse Paranasal Sinus Mucoceles

ObjectiveThis study aimed to investigate that complicated mucoceles of paranasal sinuses and their clinical presentation, complications of relations with size, destructions areas, extension limits in affected patients.Materials and methodsA retrospective review was performed on patients who were diagnosed and treated as paranasal sinus mucoceles at ENT department from 2002 to 2013 years. Patients' demographic data, mucoceles location, symptoms, surgical approach and complications were evaluated.ResultsThe study group included 9 male and 10 female patients with a mean age of 45,0 years (range, 12-76 years). This case series include fronto-ethmoidal complex (52,6%), followed by frontal (26,3%), maxillary (15,7%) and sphenoid sinus mucoceles (5,2%). Endoscopic sinus surgery (ESS) was performed on 11 patients (57.8%); endoscopic procedures included marsupialization through an infundibulotomy, associated with an anterior ethmoidectomy and maxillary sinus antrostomy. Four patients (21%) underwent an external surgical procedure. 8 patients (42%) were treated by a combination of both endoscopic and external approaches such as trephination of the anterior wall of the frontal sinus, osteoplastic flap approach, Caldwell-Luc operation, anterior craniotomy and Lynch procedure. Complications occurred only in 2 cases (10.5%).ConclusionThe majority of patients with extensive paranasal sinus mucoceles exhibited ophthalmologic and intracranial symptoms. A satisfactory outcome can be achieved after surgical treatment of both endoscopic and external approaches.
