Abstract

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.

非综合征性小脑症患者的头颅测量评估：与对照组的横断面研究。

目的：评价和比较非综合征性小脑症患者的头颅测量特征。方法和结果：本横断面比较研究评估了16例非综合征性小脑畸形患者和48例无小脑畸形患者（n = 48）的头颅测量特征。回顾性分析采用侧位脑电图、骨断层摄影、牙模、面部照片和口内照片进行。结论：小畸形患者表现为II类骨骼及头侧畸形，易发生上切牙垂直运动，下切牙突出。此外，他们还表现出下中线向患侧偏移的趋势。
