脑膜旁横纹肌肉瘤（PM-RMS）是一种罕见的侵袭性软组织恶性肿瘤，主要发生在头颈部区域。 RMS 的标准治疗方法涉及多模式治疗方案，包括手术、化疗和放疗。然而，头颈部 RMS 年轻患者常规使用放疗和化疗可能会对牙齿发育产生不利影响，从而给规划牙科干预带来挑战。本病例报告概述了 RMS 患者的牙齿和面部发育后果。一名 13 岁儿童，在 7 岁时接受了化疗和放射治疗干预来治疗 PM-RMS。治疗后，孩子出现了严重的牙齿并发症，包括牙根生长停滞和张口受限。该病例强调了肿瘤学家、牙医和其他医疗保健专业人员之间跨学科合作的必要性，以减轻对牙齿健康和整体生活质量的不利影响。接受横纹肌肉瘤放化疗的患者。© 2024。作者。

Parameningeal rhabdomyosarcoma (PM-RMS) is a rare and aggressive soft tissue malignancy that primarily occurs in the head and neck region. The standard treatment approach for RMS involves a multimodal therapy regimen, which includes surgery, chemotherapy, and radiotherapy. However, the routine use of radiotherapy and chemotherapy in young patients with RMS in the head and neck region can lead to adverse effects on dental development and thereby, pose a challenge in planning dental intervention.This case report outlines the dental and facial developmental consequences in a 13-year-old child, who received chemo-radiotherapeutic intervention at the age of 7 years for the management of PM-RMS. Following treatment, the child exhibited significant dental complications, including arrested root growth and restricted mouth opening.This case highlights the necessity for interdisciplinary collaboration between oncologists, dentists, and other healthcare professionals to mitigate the adverse effects on dental health and overall quality of life in patients undergoing chemo-radiotherapy for rhabdomyosarcoma.© 2024.
