This case report describes severe dento-maxillofacial defects after chemoradiation therapy in a child aged 9 years 6 months with a parameningeal rhabdomyosarcoma. A clinical and radiologic (apical dental radiographs, orthopantograph, lateral skull roentgenogram) dental follow-up over 4 years showed such dental abnormalities as root blunting, mild to severe root shortening, premature closure of the root apices, and severe radiation caries. Craniofacial morphology evaluated by cephalometric analysis and dental models showed deficiency with mandibular and maxillary hypoplasia.
本病例报告描述了一名9岁6个月患有颅底旁横纹肌肉瘤的儿童在放化疗后出现的严重牙颌面缺损。一项为期4年的临床及放射学（根尖牙片、全景曲面断层片、头颅侧位X线片）牙科随访显示出牙根变钝、轻度至重度牙根缩短、根尖过早闭合以及严重放射性龋齿等牙齿异常情况。通过头影测量分析和牙模评估的颅面形态显示存在下颌骨和上颌骨发育不全的缺陷。
