Deepening of the nasofrontal groove is considered a fiddly task. The unwonted chisel ostectomy technique (Skoog, 1974; McCarthy, 1990; Aiach and Levignac, 1991) was therefore modified and evaluated both experimentally and clinically. The hump is removed in one piece together with the nasal bones up to the horizontal part of the frontonasal suture. To accomplish this, the reduction osteotomy has to be performed in a wave line fashion. The depth of resection in the sellion area depends upon the aesthetic planning. In cases with most severe hypertrophy, the osteotome enters the vertical frontonasal suture behind the nasal bones and in front of the nasal spine of the frontal bone. The nasal bones are disarticulated with a levering movement. Cadaver studies demonstrate the safety of the technique: no fracture lines were detected in the frontal process of the maxilla, ethmoid, frontal or lacrimal bones, by either clinical inspection, or by standardised radiological examination. The clinical cases show a convincing outcome.
鼻额沟加深被认为是一项棘手的任务。因此，对不寻常的凿骨切除术技术（斯库格，1974年；麦卡锡，1990年；艾亚克和勒维尼亚克，1991年）进行了改进，并在实验和临床方面进行了评估。将驼峰连同鼻骨一起整块切除至鼻额缝的水平部分。为此，截骨复位术必须以波浪线方式进行。蝶鞍区的切除深度取决于美学规划。在最严重的肥大病例中，骨凿进入鼻骨后方和额骨鼻嵴前方的垂直鼻额缝。通过撬动动作使鼻骨分离。尸体研究证明了该技术的安全性：通过临床检查或标准化放射学检查，在上颌骨、筛骨、额骨或泪骨的额突中均未检测到骨折线。临床病例显示出令人信服的结果。
