Abstract:
Although there has not yet been a clear determination of the structures responsible for nasal tip support, it is generally agreed that for Caucasians the components of nasal tip support include the attachment between the upper and lower lateral cartilage, the attachment between the lateral crus and the pyriform aperture, the attachment between the paired domes of the lower lateral cartilages, and the medial crural attachments of the caudal septum. To our knowledge, there has been no anatomical study of the nasal tip supporting structures for Asian patients. The purpose of this study is to determine these structures and how they differ from those of Caucasian patients. Ten noses of fresh cadavers were investigated. Dissection was performed and the above-mentioned nasal tip supporting structures were observed and excised. Histological examination was done with hematoxylin and eosin stains and Van Gieson elastin stains. Based on our results, we propose that the structures between upper and lower lateral cartilages, between lateral crus and pyriform aperture, between the paired domes of lower lateral cartilages should referred to as an intercartilaginous ligament, sesamoid fibromuscular tissure, and interdomal loose connective tissue, respectively. There is no identified specific tissue between medial crus and caudal septum. We consider that the loose connection between the domes of the middle crura and the lack of a specific structure between the medial crus and caudal septum might be the reasons why the nasal tips of Asian patients tend to be broad and unprojected with a wide base.
