The study evaluated the effectiveness of the nasolabial flap for treating oral submucous fibrosis (OSMF) in 75 patients.
Post-surgery results showed that 65.3% of patients achieved normal mouth opening, while 5.3% had unsatisfactory outcomes.
The nasolabial flap is a viable surgical option due to its ease of use, good blood supply, low complication rates, although it may leave a surgical scar that can be corrected later.
