PURPOSE: To review @entity1 with chronic oroantral and oronasal fistula who underwent surgical correction. MATERIAL AND METHODS: Twenty-seven @entity1 with chronic @entity8902 who underwent surgical correction in the Hacettepe University Faculty of Medicine Department of Otorhinolaryngology Head and Neck Surgery between 1968 and 2001 were reviewed retrospectively. RESULTS: @entity33 were used for surgical correction. The underlying factors were tooth extraction in 13 @entity1 (48%), @entity5 in 5 (18.5%), @entity4034 in 3 (11%), Caldwell-Luc procedure in 2 (7.5%), @entity130 in 2 (7.5%), @entity45 in 1(3.7%), and correction of septal perforation in 1 (3.7%). Among the fistulas, 23 were oroantral, 3 were oroantronasal, and 1 was oronasal, respectively. Two @entity1 required revisional repairment. The surgical procedure failed in 1 @entity6 @entity1 and 3 @entity1 with prior history of external radiotherapy. CONCLUSION: Tooth extraction was the most common etiologic factor, and @entity5 should be excluded in all @entity1 . The outcome may not be satisfactory in @entity1 with @entity262 and in @entity1 with history of radiotherapy. Multiple surgical interventions may be necessary only on rare occasions.
