Closure of Oronasal Fistula by Palatal Rotational Flap: Case Report with Two Years follow-up

Abstract

Background/Aim: Hard palate fistulas are due to pathologies such as noma, syphilitic gom, leprosy, leishmaniasis, radiotherapy, removal of cysts or tumors of the sinus or palate, trauma or tooth attraction. Symptoms of palatal fistulas include hypernasality in the phonation due to nasal air escape during a speech, nasal cavity fluid flow, and infection due to food accumulation. Surgical repair of palatal perforations is technically difficult and complicated. Different surgical methods can be used depending on the size and location of the defect. Among these techniques, the locoregional flap types used are palatal flap, nasolabial flap, a buccal fat pad and tongue flap.
