[Abstract] Objective To explore a method to repair nasal side mucosa of wide incomplete cleft palate and reduce the tension of wound by using oral mucosa flap in the top of fissure. Methods 27 cases of wide incomplete cleft palatal were included in the study. On the basis of two-flap palatoplasty, the triangular oral mucosa flap in the top of fissure was turned and sewed with side mucosa to repair nasal side mucosa of wide palatal cleft. Results Without postoperative active bleeding, airway obstruction and wound infection, 27 cases had been repaired satisfactorily by this procedure. 1-3 months followed up demonstrated that all the wounds healed well without wound dehiscence or fistulas and the scars in the palate were not severe. Conclusion Using oral mucosa flap in the top of fissure to repair nasal side mucosa of wide palatal cleft can get a reduced tension and correspondingly increase the width of mucoperiosteal flaps so as to decrease incidence rate of palatal fistulas and reduce formation of scars.
