临床资料本组共5例,男3例,女2例,左侧3例,右侧1例,双侧1例,年龄12～16岁,5例均为唇裂或腭裂整复术后,临床检查见患侧上唇以及患侧鼻翼塌陷,鼻孔扁而宽,全部病例均存有口鼻瘘,前牙列不整,均可扪及齿槽突裂隙,双侧齿槽突裂者前颌骨活动。X光片显示裂隙处骨质缺损,5例术前均未接受过齿槽突裂整复。手术方法常规消毒后,局麻下进行手术;沿齿槽突裂隙及相邻两侧龈缘切开粘骨膜,切口大小根据裂隙宽窄而定,然后向裂隙的两侧及鼻底区域分离,掀起粘骨膜瓣,缝合裂隙处粘骨膜,如裂隙宽张力较大者,可在齿槽突唇颊侧作与裂隙平行的切口,以利组织移位,使之形成一个口在龈缘,底在鼻底的袋状受植床;将消
Clinical data The group of 5 patients, 3 males and 2 females, left 3 cases, right 1 case, bilateral in 1 case, aged 12 to 16 years old, 5 cases were cleft lip or cleft palate surgery, clinical Check the affected side of the upper lip and ipsilateral collapse of the nose, flat and wide nostrils, nose and mouth fistula are present in all cases, anterior dentition irregularity, palpable alveolar cleft, bilateral crenulum rupture premaxillary activity . X-ray film showed bone defects in the fracture, 5 cases had not received crenulation surgery before surgery. Surgical methods routine disinfection, under local anesthesia surgery; along the alveolar cleft and gingival margins along the adjacent sides of the mucoperiosteal incision, the size of the incision according to the width of the slit, and then to both sides of the fissure and nasal floor area separation, off Mucoperiosteal flap, suture crack mucoperiosteal crevices, such as the greater width of the cleft fissure in the alveolar buccal side of the buccal cleft parallel to the incision, in order to facilitate tissue translocation, so that the formation of a mouth in the gingival margin, the bottom of the The bottom of the bag by the implant bed; will eliminate
