We propose a standardized numerical classification system for palatal fistulas. Its clinical adoption may prospectively clarify ambiguities in the literature and facilitate future cleft palate research and clinical practice.

Using the proposed algorithm in this single-surgeon consecutive series of 268 cases, the authors achieved the lowest reported incidence of postoperative fistulas in all forms of palatal procedures, including the lowest incidence (0.76 percent) of symptomatic palatal fistulas following primary Furlow palatoplasty.
