The Role of Frontal Sinus Obliteration in the Era of FESS

ObjectiveTo determine the current indications for osteoplastic frontal sinus obliteration (OFSO) for the treatment of inflammatory frontal sinus disease.MethodsRetrospective case series from a single tertiary care facility. The medical records of 35 patients who underwent OFSO for chronic frontal sinusitis (n=26) and frontal sinus mucocele (n=9) between 1995 and 2007 were reviewed. Data regarding age, gender, date and nature of previous frontal sinus operation(s), pre-operative imaging, pre-operative diagnosis, and operative complications were culled.ResultsThere were 19 males and 16 females with an age range of 19 to 76 years. All patients had pre-operative sinus CT, while 6 patients had additional MRI. Among the 9 patients diagnosed with frontal sinus mucocele, OFSO was first-line treatment in 8 and salvage for 2 failed endoscopic masupialization procedures in 1. Among the 26 patients with chronic frontal sinusitis, OFSO was first-line in 9 and salvage for failed frontal sinus surgery in 17. The failed ...
