The early results of a combined method of augmentation for extreme mandibular atrophy (Farmand, 1986) are evaluated in 40 patients over a period of up to 12-15 months after operation. The method combines the advantages of the classic augmentation procedure with laminated split ribs (Obwegeser, 1967, 1977) with those of the sandwich technique (Schettler, 1976). In cases with mucosa of good quality and quantity a simultaneous lingual and vestibular sulcoplasty is performed, thus giving the patient in a single-stage operation, conditions for adaptation of well-fitting dentures. It could be shown, that during the investigation time the mean resorption rate was 7-16% of the total anterior mandibular height. In the lateral parts, the resorption is in most cases less than one third of the transplant. 10 of 15 patients without simultaneous sulcoplasties needed a secondary soft tissue procedure after 9 months. 11 of 25 patients with simultaneous sulcoplasties needed the secondary operation. There is only one patient with a residual hypoaesthesia of the mandibular nerve. Local complications were seen in 22 cases and these were treated adequately.
对40例患者采用联合方法治疗严重下颌骨萎缩（法曼德，1986年）的早期结果进行了评估，随访时间长达术后12至15个月。该方法结合了经典的叠层劈开肋骨增高术（奥布韦格泽尔，1967年、1977年）和三明治技术（谢特勒，1976年）的优点。对于黏膜质量和数量良好的病例，同时进行舌侧和前庭沟成形术，从而在一期手术中为患者提供适配良好假牙的条件。结果表明，在研究期间，下颌前部总高度的平均吸收速率为7%至16%。在外侧部分，大多数情况下吸收小于移植骨的三分之一。15例未同时进行沟成形术的患者中有10例在9个月后需要进行二次软组织手术。25例同时进行沟成形术的患者中有11例需要二次手术。仅有1例患者存在下颌神经残余感觉减退。观察到22例局部并发症，并进行了适当治疗。
