Insights

This study introduces a multi-layer repair technique for palatal fistulas, utilizing a collagen graft. This effective method successfully prevented fistula recurrence in two pediatric patients.

Area of Science:

  • Plastic Surgery
  • Craniofacial Surgery
  • Pediatric Surgery

Background:

  • Palatal fistulas occur in 7.7-35% of patients following cleft palate repair.
  • Previous repairs using the Furlow technique were unsuccessful in two patients, necessitating reintervention.

Observation:

  • Two pediatric patients with recurrent palatal fistulas (Pittsburgh type III and V) were treated.
  • A multi-layer repair technique was employed, incorporating a local rotational flap and a collagen matrix graft.

Findings:

  • The collagen matrix was placed between the nasal and oral layers, with sutures reinforced by a fibrin hemostatic adhesive.
  • Both patients achieved successful fistula closure with no recurrence after a 2-year follow-up period.

Implications:

  • This three-layer closure technique is a simple, safe, and effective method for treating palatal fistulas.
  • Resorbable collagen membranes act as a scaffold, promoting tissue regeneration and mucosal healing, thus avoiding refistulization.
