单侧唇腭裂中牙槽嵴裂的手术治疗

为１６例单侧唇腭裂中的牙槽嵴裂患者，采用自体髂骨骨松质（１３例）或羟基磷灰石（３例）充填，并以上唇粘膜瓣和裂隙两侧粘骨膜瓣移转封闭裂隙的治疗方法。其中１２例随访１～５年，自体骨移植者有９例，全部发生骨连续，并有７例或从骨移植区长出。羟基磷灰石者３例无一例有牙萌出。认为缺损修补以自体骨移植为好，羟基磷灰石不宜用于未成年人。

Surgical treatment of unilateral alveolar cleft

In this study, 16 cases of unilateral alveolar cleft with cleft lip and palate were repaired with autografts of cancellous bone(13 cases) or hydroxyapatite(3 cases). The grafts were covered by reflected mucoperiosteal flaps and a mucosal flap from the upper lip. Twelve of the thirteen cases were followed up for 1-5 years. Nine of whom using cancellous bone had bony continuity of the maxilla and 7 cases erupted permanent maxillary canines within the area of autografts. None of the 3 cases using hydroxyapatite erupted a canine tooth. The results showed that autograft was better than hydroxyapatite in terms of maxillary canine eruption.
