Nasal septal defects may present with no clinical symptoms to dryness, nasal obstruction, pain, mucosal injury, crusting, epistaxis, rhinorrhea, nasal twang in speech, hyposmia, and breathing difficulties. Prosthetic rehabilitation of these defects may lead to improvement in these conditions. This case report describes the construction of a custom-made two-piece, magnet-retained nasal prosthesis fabricated in heat-cured acrylic resin. Intra-nasal and extra-nasal alginate impressions were splinted with soft plaster. Sequential model pouring was done for convenient access to the complicated intra-nasal anatomy. Two individual nasal stent waxups, containing two magnets with opposing poles facing each other, were well adapted to their respective medial nasal walls and anterior retentive rounded tips. Waxups were processed in heat-cured acrylic resin and delivered after finishing and polishing. Patient's symptoms were relieved, while maintaining the nasal patency. Such inexpensive method with a tissue-friendly material may prove beneficial for rehabilitation of larger nasal septal defects. Key Words: Nasal septal defects, Rehabilitation, Acrylic resin, Prosthesis.
鼻中隔缺损可能没有临床症状，也可能出现干燥、鼻塞、疼痛、黏膜损伤、结痂、鼻出血、流涕、言语鼻音、嗅觉减退和呼吸困难。这些缺陷的假体修复可能会改善这些情况。本病例报告描述了用热固化丙烯酸树脂制作定制的两件式、磁铁固位鼻假体的制作过程。鼻腔内和鼻腔外的藻酸盐印模用软石膏夹板固定。为了方便进入复杂的鼻腔内解剖结构，进行了连续的模型浇注。两个单独的鼻支架蜡模，包含两个相对磁极的磁铁，很好地适应了各自的鼻中隔内壁和前保留的圆形尖端。蜡模用热固化丙烯酸树脂加工，完成和抛光后交付。患者的症状得到缓解，同时保持了鼻腔通畅。这种使用组织友好材料的廉价方法可能对较大的鼻中隔缺损的修复有益。
