Cleft Palate Fistula: A Review.

Background: The development of postoperative oronasal fistulae (ONF) is a complication that plagues all cleft surgeons to varying degrees. There is extensive literature discussing the incidence, functional impact, and treatment of ONF. The goal of this article is to provide an extensive review of the literature discussing the incidence, causative factors, functional impact, classification systems, and treatment of ONF. Methods: A literature review was performed using PubMed using the Medical Subject Heading terms "cleft palate" AND "fistula" OR "palatal fistula" OR "oronasal fistula". After review, a total of 356 articles were deemed relevant for this study. Results: Information regarding ONF care, prevention, and management in patients with cleft palate was collected from the articles included in this review. Treatment of ONF remains a challenging problem as there is not a consensus in the available literature on the best palatoplasty techniques for their prevention and treatment. A myriad of reconstructive options and adjunctive therapies exist, and their use is guided by the size and location of the fistula. Conclusions: Fistula treatment should be tailored to the specific needs of the patient, and consideration must be given to not only the ONF itself but also the patient's stage of growth and development. Large-scale, multicenter studies are needed in which ONF are described using standardized nomenclature, and improved outcomes reporting is necessary to better define an algorithm for a truly holistic approach to palate surgery and reduce the incidence of palatal fistula.
