The rehabilitation of a maxillectomy patient involves meticulous treatment planning and designing. Lack of retention and facial support and limited mouth opening are the major issues that lead to functional and psychological trauma in post-maxillectomy patients. The successful rehabilitation of a maxillary defect includes restoring the function, esthetics, and a complete obturation of the defect, enabling the patient to feed without nasal regurgitation. This case report describes the fabrication of an obturator with a modified design, namely a split-antral hollow bulb obturator and oral part that is retained with a ball attachment, for a patient with right-side acquired maxillary defect due to recurrent myxoma. The primary advantage of this modification is enhanced facial support and a self-retentive antral obturation that improved the quality of life of the patient after an extensive maxillectomy.
上颌骨切除术后患者的康复需要精心的治疗计划和设计。固位不足、面部支持缺失以及张口受限是导致上颌骨切除术后患者出现功能和心理创伤的主要问题。上颌骨缺损的成功修复包括恢复功能、美观以及完全封闭缺损，使患者能够正常进食而无鼻反流现象。本病例报告描述了为一名因复发性黏液瘤导致右侧获得性上颌骨缺损的患者制作一种改良设计的阻塞器，即分体式窦腔空心球阻塞器和通过球附着固位的口腔部分。这种改良的主要优点是增强了面部支持以及实现了窦腔阻塞器的自我固位，从而提高了广泛上颌骨切除术后患者的生活质量。
