SOARES, Isadora Mello Vilarinho et al. Oronasal fistula after palatoplasty in cleft patients. Rev. cir. traumatol. buco-maxilo-fac. [online]. 2016, vol.16, n.2, pp. 31-35. ISSN 1808-5210.

The oronasal fistula (ONF) is the main postoperative sequel of palatoplasty and can leads to functional problems such as hypernasality of voice and regurgitation of food through the nose. This condition affects the outcome of treatment of cleft palate and is challenging for the multidisciplinary team. This paper reports three cases of patients with cleft lip and palate who presented ONF after palatoplasty. In these cases, type VII ONF (alveolar in the labial region) were diagnosed, and were caused by excessive muscle tension on the suture after palatoplasty. The treatment consisted of a surgery for closure of the fistula through the mucoperiosteal flap, which was carried out performed by a maxillofacial surgeon. It is essential an appropriate surgical planning in order to promote better prognosis for the patient aiming better quality of life.
