上颌Le Fort Ⅰ型截骨术对鼻形态影响的研究进展

Progress of research on effect of Le Fort Ⅰ maxillary osteotomy on three-dimensional nasal morphology

上颌Le Fort Ⅰ型截骨术是正颌外科中矫治上颌骨畸形最常采用术式之一。但是,上颌骨的移动、肌肉的剥离会影响周围软组织的形态,其中鼻形态的改变越来越受到重视。已有研究报道,正颌手术后鼻形态的不利改变是降低患者手术满意度的主要原因之一。明确上颌Le Fort Ⅰ型截骨术对鼻形态的影响能够帮助医生更准确地预测术后鼻形态的变化,从而优化手术设计、提高医患沟通效率。本文将对上颌Le Fort Ⅰ型截骨术后鼻部形态变化的研究进展作一综述,旨在为临床实践提供相应的参考。

Le FortⅠosteotomy is commonly used for correction and treatment of maxillofacial deformities by re-positioning the maxilla.However,Le FortⅠsurgery may lead to surgical soft tissue alterations in nasal morphology,which should be predicted and explained to the patient.It has been reported that the adverse change of nasal morphology after orthognathic surgery is one of the main reasons of decreased patient's satisfaction.Therefore,understanding such changes is vital for surgical planning and for obtaining appropriate informed consent.In this paper,we reviewed the progress in studieson morphological changes in the nose after Le FortⅠosteotomy in order to provide reference for clinical practice.
