唇裂患者常伴有不同程度的鼻畸形,这类畸形可有以下表现: ①患侧鼻翼软骨位置异常。它常在两个平面上发生不正常的扭转:一为矢状面上反时针方向的扭转,使鼻翼软骨内侧板接近于鼻小柱的基底;其二为水平面上鼻翼软骨从鼻尖向前下方扭转,使软骨的大部分接近于唇部。由于软骨的位置异常而产生了鼻外观的畸形。②患侧鼻小柱变短。③患侧鼻翼的基底太宽。 Patients with cleft lip often accompanied by varying degrees of nasal deformity, such deformities may have the following manifestations: ① ipsilateral alar cartilage abnormalities. It often occurs in two planes abnormal twist: one for the sagittal anti-clockwise direction of rotation, so that the alar cartilage medial plate close to the base of the columella; the second level of the alar cartilage forward and downward from the nose Turn so much that most of the cartilage is near the lip. Abnormal nasal appearance due to abnormal cartilage position. ② ipsilateral nasal shortened. ③ the affected side of the base of the nose is too wide.
