This study was to investigate the nasal musculature and its relationship with the deformities of the unilateral cleft lip nose.
The anatomic and histological examination and comparison of the musculus depressor septi nasi (MDSN) were performed in 33 normal cadavers and 30 patients with unilateral cleft lip undergoing the operation for secondary nasal deformities.
It was found that the MDSN in the cleft side of a unilateral cleft lip nose is lacking.
Because of the anatomic deficiency on the cleft side, the function of the normal side is pathologically increased. The functional imbalance between the normal and abnormal side may bring about dislocation and malformation of the base of nasal columella as well as the septal structures.
本研究旨在探究鼻肌及其与单侧唇裂鼻畸形的关系。
对33具正常尸体及30例接受二期鼻畸形手术的单侧唇裂患者的降鼻中隔肌进行了解剖学和组织学检查及对比。
发现单侧唇裂鼻裂侧的降鼻中隔肌缺失。
由于裂侧存在解剖学缺陷，正常侧的功能在病理上增强。正常侧与异常侧之间的功能失衡可能导致鼻小柱基部以及鼻中隔结构的移位和畸形。
