Abstract:
Oronasal fistula is defined as an abnormal duct, connecting the nasal with the oral cavity. We present an extremely rare case of oronasal fistula associated with rhinolithiasis. The particular case presents the unique feature of a palatal defect, being large enough to enable the in toto removal of the rhinolith. A 2-layer closure of the fistula was finally undertaken, by utilizing a vestibular and a palatal mucoperiosteal flap.
