中文摘要
目的： 评估并比较非综合征型小耳畸形患者的头影测量特征。
方法与结果： 本横断面比较研究评估了16例非综合征型小耳畸形患者和48例无小耳畸形患者（n = 48）的头影测量特征。采用侧位头影测量片、全景片、牙模、面部照片和口内照片进行回顾性分析。小耳畸形组的ANB（p = 0.044）、FMA（p < 0.001）、SN.GoGn（p = 0.003）、Y轴（p = 0.024）、LAFH（p < 0.001）和1-NB（p = 0.014）较高，而1.NA（p = 0.018）和IMPA（p = 0.029）相对于对照组较低。12例患者下颌中线偏向小耳畸形侧；1例患者为左侧小耳畸形且中线偏向右侧，3例患者未出现下颌中线偏斜。
结论： 小耳畸形患者表现出II类骨骼型和长头型模式的倾向，上切牙有垂直方向移动的倾向，以及下切牙前突。此外，他们表现出下中线偏向患侧的倾向。
英文摘要
AIMS: To assess and compare the cephalometric characteristics of patients with nonsyndromic microtia.
METHODS AND RESULTS: This cross-sectional comparative study evaluated the cephalometric characteristics of 16 patients with nonsyndromic microtia and 48 patients without microtia (n = 48). A retrospective analysis was performed using lateral cephalograms, orthopantomograms, dental casts, facial photographs, and intraoral photographs. ANB (p = 0.044), FMA (p < 0.001), SN.GoGn (p = 0.003), Y-axis (p = 0.024), LAFH (p < 0.001), and 1-NB (p = 0.014) were higher in the microtia group, whereas 1.NA (p = 0.018) and IMPA (p = 0.029) were lower relative to controls. Twelve patients had deviation of the mandibular midline to the microtia side; one patient had left-sided microtia and deviation of the midline to the right side, and three patients did not exhibit mandibular midline deviation.
CONCLUSION: Patients with microtia showed prevalence of a Class II skeletal and dolichocephalic pattern, predisposition to upper incisor movement in the vertical direction, and lower incisor protrusion. In addition, they showed a tendency toward deviation of the lower midline to the affected side.
