Rehabilitation of the front palate fistula with adjuvant derma transplantation in Japanese big ear rabbits / 实用口腔医学杂志

ABSTRACT

Objective: To study the rehabilitation efficiency of adjuvant derma transplantation in treatment of front palate fistula. To find a better way to solve the problem of correcting the front fistula in short of the nearby tissue. Methods: Established the front fistula model in the oral and nasal cavity in the front of the palate with surgery. 30 Japanese big ear rabbits were divided into 2 groups. One month after operation, 15 rabbits were operated with the nearby tissue into the inner of nasal cavity and by transplanting their back skin while the others were treated only with the nearby tissues. The rehabilitation process and the histological changes of the palate were observed. Results: All dermal flaps survived after transplantation. This surgical method got a satisfying effect(P<0.05). The rate of success for correcting with single nearby tissues was lower. Conclusion: Adjuvant derma transplantation for rehabilitation of the front palate fistula is effective and reliable in the rabbits. The combination of the nearby tissue and homeochronous derma transplantation might be a good mode for correcting the front fistula in short of the nearby tissues.
