[Frontal sinus mucocele].

Between 1995 and 2000 twenty-two patients were treated for frontal sinus mucocele in the Department of Otorhinolaryngology of Medical University of Warsaw. History and physical examination revealed several-year-old chronic rhinosinusitis (CRS) in all but one cases. Thirteen patients had been previously operated on for this reason at least once. Conservative management, mainly in periods of symptom deterioration, was applied in other patients. The only patient with negative history of CRS had undergone in the past head injury with fracture and dislocation of the anterior wall of the frontal sinus, in the past. All patients were treated surgically with use of the intranasal endoscopic approach in 15 cases, osteoplastic surgery of the frontal sinus in 5 cases and combination of both in 2 cases. Diagnostic and management protocol is discussed and compared with data presented in the literature.
