Pakistan Comprehensive Fistula Classification: A Novel Scheme and Algorithm for Management of Palatal Fistula/Dehiscence.

BACKGROUND: It is not easy to find a management-based classification of palatal fistula in the literature. A few attempts have been made to classify the wide variety of fistulae that do not describe the fistula details comprehensively and guide toward its management. The authors have come across a wide variety of fistulae that could not be classified according to any of the prevailing classification systems. The presented classification gives a clear and exact understanding of location and size of fistula/dehiscence. Palatal function has been included as one of the important determinants for devising a management plan. Based on this classification, the authors have proposed an algorithm that encompasses clear guidelines for surgical treatment of these fistulae.

METHODS: Over the past 15 years, the authors' team operated on 2537 palatal fistula patients. The medical records of these patients were reviewed to determine the location, size, and velopharyngeal competence. A new classification and algorithm were developed.

RESULTS: Of 2537 patients, 2258 had midline fistulae, 208 had lateral fistulae, and 53 had subtotal fistulae. There were 18 patients with dehiscence. Recurrence developed in 181 patients.

CONCLUSION: The authors believe that this classification and algorithm can help follow a practical approach to manage palatal fistulae and dehiscence.
