Osteoplastic flap for obliteration of the frontal sinus: Five years' experience

The objective of this retrospective study wens to evaluate the osteoplastic flap (OPF) for the obliteration of the frontal sinus in this current era of endoscopic management of frontal sinus disease. A review of consecutive OPF procedures (n = 43) performed by the senior author (J.A.D.) from 1992 to 1997 was carried out. Data were gathered regarding chief symptom, medical history, previous sinus surgery, endoscopic findings in the office and at surgery, CT scan findings, and follow-up results (mean 19.4 months). Previous endoscopic management of frontal sinus disease had failed in 24% of patients; 97% had eventual resolution of frontal sinusitis with OPF. After OPF, 63% also had improvement or resolution of disease in other paranasal sinuses. Statistically significant, positive correlations (P < 0.05) were noted between the resolution of frontal sinusitis and improved or resolved pain, as well as the resolution of frontal sinusitis and improved or resolved infections in other paranasal sinuses. In 1998 OPF remains the standard for treating frontal sinus disease refractory to other methods. OPF can decrease the pain associated with frontal sinus infections and has a positive impact on inflammatory disease in other paranasal sinuses.
