Rehabilitation of patients who have undergone bilateral maxillectomy is difficult because of extensive loss of bone and soft tissue. In this clinical report, prosthodontic rehabilitation of oral function in a bilateral maxillecitomy patient combined with a new fibular osteocutaneous flap, which was designed to have two oronasal slits for the retention of an obturator prosthesis, was described. A 58-year-old man with a maxillary alveolar carcinoma underwent bilateral maxillectomy. The defect was reconstructed using a vascularized fibular bone wrapped circumferentially with a peroneal flap, which was fixed with miniplates between the right malar prominence and cut edge of the left zygoma remaining two slits anterior and posterior to the graft. Two and half weeks after the surgery, a delayed surgical obturator was delivered and an obturator prosthesis was delivered 6 weeks after the surgery. This obturator prosthesis could be extended into the slits to engage the tissue undercuts, and was stable during use. Mastication, deglutition, articulation and the mid-facial profile of the patient were rehabilitated. After installation of the obturator prosthesis, relining of the prosthesis base was carried out alongside the healing process of the graft, and adjustment of occlusions and high-pressure spots was carried out. No clinical disorders were observed either in the grafted tissue or the obturator prosthesis with a 3-year prognosis. Newly designing a fibular osteocutaneous flap combined with tissue-borne obturator prosthesis is one successful approach to the restoration of oral function, and increases the patient's quality of life after bilateral maxillectomy.
双侧上颌骨切除术后患者的康复治疗具有挑战性,因为骨组织和软组织大量缺失。在本临床报告中,描述了一名双侧上颌骨切除患者的口腔功能修复,该修复采用了一种新的腓骨骨皮瓣,其设计有两个口鼻裂隙以固定阻塞器假体。一名58岁的上颌牙槽癌男性患者接受了双侧上颌骨切除术。缺损采用带血管蒂的腓骨进行重建,腓骨瓣环绕包裹,通过微型钢板固定于右侧颧骨突出部与左侧颧骨切缘之间,在移植骨前后各保留一个裂隙。术后两周半制作延迟手术阻塞器,术后6周制作阻塞器假体。该阻塞器假体可延伸至裂隙中以卡合组织倒凹,使用过程中稳定。患者的咀嚼、吞咽、发音及面中部外形均得以恢复。安装阻塞器假体后,随着移植骨的愈合过程对假体基托进行重衬,并对咬合和高压点进行调整。随访3年,移植组织及阻塞器假体均未出现临床问题。新设计的腓骨骨皮瓣联合组织支持式阻塞器假体是恢复口腔功能的一种成功方法,提高了双侧上颌骨切除术后患者的生活质量。
