Hemifacial atrophy (Parry-Romberg syndrome) is a rare but well-recognized condition. The developmental effects on facial and oral structures have been well documented in the literature. However, the etiology of hemifacial atrophy remains unknown. Previous reported alterations in tooth growth and development include delayed tooth eruption, abnormal root morphology, and malocclusion but not root resorption. This report presents the orofacial changes from hemifacial atrophy in a 22-yr-old woman and describes the occurrence of root resorptions in two regions affected by this condition. The concurrent presence of root resorptions in both the maxilla and mandible in the regions showing the most severe dental malformations points to root resorption as an additional complication of hemifacial atrophy.
半侧颜面萎缩（帕里 - 罗姆伯格综合征）是一种罕见但已被充分认识的病症。其对面部和口腔结构发育的影响在文献中已有充分记载。然而，半侧颜面萎缩的病因仍不明了。先前报道的牙齿生长和发育改变包括牙齿萌出延迟、牙根形态异常和错牙合，但未提及牙根吸收。本报告展示了一名22岁女性因半侧颜面萎缩导致的口面部变化，并描述了在受该病症影响的两个区域出现的牙根吸收情况。在上颌骨和下颌骨中，显示出最严重牙齿畸形的区域同时存在牙根吸收，这表明牙根吸收是半侧颜面萎缩的一种额外并发症。
