Abstract

Rhinoplasty outcome may depend on different factors and bony dorsum shape has proven to significantly influence the lateral view result. The "Keystone angle" corresponds to the osseocartilaginous angle formed between bony and cartilaginous dorsum. Usually, the "V" shaped bony dorsum is characterized by a more acute "Keystone angle" compared to the "S" shaped bony dorsum. To achieve the ideal dorsum flatness, corresponding to a "Keystone angle" of 180°, different techniques may be used. Bearing these concepts in mind we suggest that preoperative assessment of the "Keystone angle" can guide the choice of the most appropriate technique for each patient. LEVEL OF EVIDENCE V: This journal requires that authors assign a level of evidence to each article. For a full description of these Evidence-Based Medicine ratings, please refer to the Table of Contents or the online Instructions to Authors www.springer.com/00266 .

基石角":保留鼻整形术中的几何学。
鼻整形手术的效果可能取决于不同的因素,而骨背的形状已被证明对侧视效果有显著影响。Keystone角 "与骨性和软骨性鼻背之间形成的骨软骨角相对应。通常,与 "S "形骨背相比,"V "形骨背的 "Keystone 角 "更尖锐。为了达到理想的骨隆背平整度,即 "基底角 "为 180°,可以采用不同的技术。考虑到这些概念,我们建议术前对 "Keystone 角 "进行评估,从而为每位患者选择最合适的技术提供指导。证据等级五:本杂志要求作者为每篇文章指定一个证据等级。有关循证医学评级的完整说明,请参阅目录或在线作者须知 www.springer.com/00266 。

期刊介绍: Aesthetic Plastic Surgery is a publication of the International Society of Aesthetic Plastic Surgery and the official journal of the European Association of Societies of Aesthetic Plastic Surgery (EASAPS), Società Italiana di Chirurgia Plastica Ricostruttiva ed Estetica (SICPRE), Vereinigung der Deutschen Aesthetisch Plastischen Chirurgen (VDAPC), the Romanian Aesthetic Surgery Society (RASS), Asociación Española de Cirugía Estética Plástica (AECEP), La Sociedad Argentina de Cirugía Plástica, Estética y Reparadora (SACPER), the Rhinoplasty Society of Europe (RSE), the Iranian Society of Plastic and Aesthetic Surgeons (ISPAS), the Singapore Association of Plastic Surgeons (SAPS), the Australasian Society of Aesthetic Plastic Surgeons (ASAPS), the Egyptian Society of Plastic and Reconstructive Surgeons (ESPRS), and the Sociedad Chilena de Cirugía Plástica, Reconstructiva y Estética (SCCP). Aesthetic Plastic Surgery provides a forum for original articles advancing the art of aesthetic plastic surgery. Many describe surgical craftsmanship; others deal with complications in surgical procedures and methods by which to treat or avoid them. Coverage includes "second thoughts" on established techniques, which might be abandoned, modified, or improved. Also included are case histories; improvements in surgical instruments, pharmaceuticals, and operating room equipment; and discussions of problems such as the role of psychosocial factors in the doctor-patient and the patient-public interrelationships. Aesthetic Plastic Surgery is covered in Current Contents/Clinical Medicine, SciSearch, Research Alert, Index Medicus-Medline, and Excerpta Medica/Embase.
