ABSTRACT

Objective To investigate the application of Haiao prosthodontics membrane in the repair of palatal fistula. Methods According to personal preference, 32 patients with palatal fistula were randomly divided into the experimental group (n=15 cases) and the control group (n=17 cases) . In the experimental group, the flap of the surrounding tissue of fistula was used as nasal layer and Haiao prosthodontics membrane was used as the oral layer for the repair of palatal fistula.In the control group, the flap of the same tissue was used as nasal layer and the flap of the ortho tissue was used as the oral layer to repair the palatal fistula. Several indexes were evaluated including the blood loss,operation time, hospitalization time, postoperative fever, postoperative complications and hospitalization expenses. Results Less blood loss, shorter operation time and shorter hospital stay were observed in the experimental group compared with the control group (P＜0.05) . The incidence of fever after operation, the temperature and the duration of the fever were significantly lower in the experimental group (P＜0.05) . The incidence of bleeding complications after operation in the experimental group were significantly lower compared with that in the control group (P＜0.05) . No significant difference of the refissure rate and hospitalization expenses was found between the two groups (P＞0.05) .Conclusion Haiao prosthodontics membrane can be used to repair some palatal fistula. Advantages include safety, reliability, mild postoperative reaction and quick recovery.
