Definitive treatment – Surgical correction

DEFINATIVE TREATMENT - SURGERY

• Direct apposition 
  • Direct apposition of the fistula is performed only if the fistula is very small.
  • The mucosa around the fistula is incised.
  • The gingival flaps are elevated and the edges of the fistula is debrided. The mucosa is then apposed over the defect.
•  Single-layer flap repair
  • If the fistula is between the gingival and buccal mucosa, the fistula is debrided and a buccal flap is advanced over the defect.
  • A rotational flap is done by debriding the fistula and rotating a mucoperiosteal hard palate flap over the defect.

  

  Palate cleft repair by mucosal flap

  • To repair lesions at the junction of the hard and soft palates, debride and close the defect with a soft palate advancement flap.
• Double-layer flap repair
  • This may be performed using tissue surrounding the fistula and a flap from the mucoperiosteum of the hard palate.
  • Create the first flap by rotating the gingival margins of the fistula medially and apposing with sutures. This flap is covered with a rotational mucoperiosteal hard palate flap.
  • Uranoplasty staphyloplasty
