Risk Factors for Oronasal Fistula in Primary Palatoplasty: A Case-Control Study From a Reference Center in Medellín, Colombia.

Background: Oronasal fistula is one of the most critical complications in primary palatoplasty, with a reported incidence between 5% and 46% with multiple associated risk factors described previously. In addition, in more than half of the patients, it implies additional surgeries, increasing risks for the patient and health care costs. In this case-control study, the authors aim to determine the specific risk factors for oronasal fistula after primary palatoplasty in the study population.
