The chin is an important determinant of the lower third of the face, carrying much significance in an esthetically balanced facial appearance. It is, however, often neglected in patients undergoing rhinoplasty procedures in the UK National Health Service (NHS). The aim of this study was to establish the percentage of a cohort of rhinoplasty patients who may also have benefited from chin augmentation.
A cross-sectional study.
The digital preoperative pictures of the last 100 patients who underwent rhinoplasty at our institution were retrieved. Four popular methods of assessment were used to assess the chin, that is, those advocated by Silver, Legan, Merrifield, and Gonzales-Ulloa. All analyses were performed on Adobe Photoshop CS4 by two ENT registrars. Values were regarded as positive when there was interobserver agreement. Relevant angles were averaged.
A total of 94 photographs were suitable for analysis. There were 58 males. Depending on the method of assessment, the percentage of males who fulfilled criteria for augmentation ranged from 17 to 62 percent and for females the range was 42 to 81 percent. Additionally, 21 percent of males were positive on three or more of the methods utilized. The respective figure was 58 percent for females.
Surgeons who practice rhinoplasty should consider making an objective assessment of the need for possible chin augmentation. Our study shows that as many as 81 percent of patients may benefit, although this figure varies with the method of assessment. In this study, the necessity for further analysis with a view to chin augmentation was more likely in women.
下巴是决定下面部三分之一外观的重要因素，对面部美观的平衡起着重要作用。然而，在英国国民保健制度（NHS）进行鼻整形手术的患者中，往往忽视了下巴。本研究旨在确定一组接受鼻整形术的患者中，有多少人可能也受益于下巴填充。
横断面研究。
我们机构检索了过去 100 名接受鼻整形术患者的数字术前照片。使用了四种流行的评估方法来评估下巴，即 Silver、Legan、Merrifield 和 Gonzales-Ulloa 所倡导的方法。由两名耳鼻喉科住院医师在 Adobe Photoshop CS4 上进行所有分析。当存在观察者间一致性时，认为值为阳性。相关角度平均化。
共 94 张照片适合分析。有 58 名男性。根据评估方法的不同，符合填充标准的男性百分比范围为 17%至 62%，女性百分比范围为 42%至 81%。此外，21%的男性在使用的三种或更多方法中呈阳性，而女性的这一比例为 58%。
进行鼻整形术的外科医生应考虑对可能需要进行下巴填充的情况进行客观评估。我们的研究表明，多达 81%的患者可能受益，尽管这一数字因评估方法而异。在这项研究中，女性更有可能需要进一步分析以确定是否需要进行下巴填充。
