背景:在肿瘤手术期间对上颌骨进行完全或部分切除会导致口鼻缺损,导致口腔颌面部功能障碍,闭孔假体是一种重要的治疗选择。传统的闭塞器制造涉及很大的复杂性,通常会导致功能和健康受损,而且很耗时。本文介绍了使用3D立体光刻技术作为指导设计的上颌闭孔假体进行缺损重建的案例。
方法:我们报告了一个14岁的女孩,她出现面部畸形,随后出现肿胀和疼痛,并到达她面部左侧的眼眶底。非对比头部磁共振成像扫描显示,左上颌骨中的肿块从颊下颌骨延伸到口腔左侧。切开活检显示肿块为成釉细胞纤维瘤。使用闭孔器对整个肿瘤进行了上颌半切除术和重建。6个月后没有明显的投诉或复发迹象。
结论:成釉细胞瘤的治疗选择包括摘除和切除。由于我们病例中病变的严重程度,整个上颌骨必须切除肿瘤,在3D打印模型的帮助下使用半结肠切除术,闭孔器用于重建。
结论:成釉细胞瘤是一种具有高复发风险的肿瘤。该病例接受了完整的半上颌切除术,同时使用3D打印的闭塞器进行修复,具有令人满意的功能和美容效果。
BACKGROUND: Complete or partial resection of the maxilla during tumor surgery causes oronasal defects, leading to oral-maxillofacial dysfunction, for which the obturator prosthesis is an important treatment option. Traditional manufacturing of obturators involves great complexity, often results in impaired function and fit, and is time-consuming. This paper presents a
case of using 3D stereolithography as a guide design for defect reconstruction with a maxillary obturator prosthesis.
METHODS: We report a 14-year-old girl who presented with facial deformities followed by swelling and pain that reached the orbit floor on the left side of her face. A non-contrast head magnetic resonance imaging scan showed a mass in the left maxilla that extended from the buccal mandible to the left side of the oral cavity. An incisional biopsy indicated that the mass was an ameloblastic fibroma. The entire tumor was treated with a hemi-maxillectomy and reconstruction using an obturator. No further complaints or recurrence signs were evident after six months.
CONCLUSIONS: Treatment options for ameloblastoma include enucleation and excision. Due to the severity of the lesion in our
case, the entire maxilla had to be removed with the tumor, using a hemimaxillectomy with the assistance of a 3D-printed model, and an obturator was used for reconstruction.
CONCLUSIONS: Ameloblastoma is a tumor with a high risk of recurrence. This
case underwent a complete hemi-maxillectomy with simultaneous repair using a 3D-printed obturator, with satisfactory functional and cosmetic outcomes.
