Effect of collagen matrix on postoperative palatal fistula in cleft palate repair.

ABSTRACT: Palatal fistula is a challenging complication following cleft palate repair. We investigated the usefulness of collagen matrix in the prevention of postoperative fistula. We performed a retrospective cohort study of patients with cleft palate who underwent primary palatoplasty (Furlow's double opposing z-plasty) in Seoul National University Children's Hospital. Collagen Graft and Collagen Membrane (Genoss, Suwon, Republic of Korea) were selectively used in patients who failed complete two-layer closure. The effect of collagen matrix on fistula formation was evaluated according to palatal ratio (cleft width to total palatal width) and cleft width. A total of 244 patients (male, 92 and female, 152; median age, 18 months) were analyzed. The average cleft width was 7.0 mm, and the average pala
