Evaluation of loss of the vestibular sulcus after repairing Bilateral alveolar clefts with bone graft in different soft tissues.pdf

1、Objective： The objective of this study is to observe the change of vestibular sulcus depth in bilateral alveolar cleft patients after secondary bo grafting using different surgical techniques(bucket-handle flap，bilat

3、different surgi techniques in the department of oral and maxillofacial surgery of Xiang Ya hospital，Central South University，three patients have bilateraI alveol cleft wit complete bilateral cleft lip and thirty nine pat

4、ients have complete bilateral cleft lip and palate．The depth of the sulcus assessed with the following grades：Grade O，no change in the depth of the vestibular sulcus；Grade I，loSS about one third of the vestibular sulcus；

5、Grade Ⅱ．loss about two thirds of the vestibular sulcus and Grade Ⅲ，the vestibular sulcu disappeared． Results： The bilateral mucosal flap was used to cover grafted bone in 36 patients；bucket handle flap was used t
