This literature review reports the current evidence for the use of zygomatic implants in head and neck oncology patients for the prosthetic rehabilitation of defects of the mid-face and maxilla.
MEDLINE, Embase and Cochrane databases were searched using strict search terms. Two independent reviewers reviewed the articles and applied inclusion and exclusion criteria.
Literature search revealed 437 articles, and following application of the inclusion criteria, 32 articles were included for analysis. Overall survival rates of 77%-100% were reported with few complications, although only four centres presented data on 20 or more patients. Primary implant placement at time of resective surgery has been shown to be an effective means of accelerating rehabilitation along with early loading protocols. The role of radiotherapy in implant failure has not been fully elucidated, and it is clear that zygomatic implants can be successfully used in the irradiated patient. Providing support for maxillary obturators was the most common use reported with both splinted and unsplinted implants.
Zygomatic implants provide remote anchorage for a variety of oral and facial prostheses that contribute to the improved function and quality of life for patients being treated for maxillary and mid-facial tumours.
本文献综述报告了颧骨种植体在头颈部肿瘤患者中的应用现状，用于修复中面部和上颌骨缺损的假体修复。
使用严格的搜索词搜索 MEDLINE、Embase 和 Cochrane 数据库。两名独立的审查员审查了文章，并应用了纳入和排除标准。
文献搜索显示有 437 篇文章，在应用纳入标准后，有 32 篇文章被纳入分析。虽然只有四个中心提供了 20 名或更多患者的数据，但报告的总体存活率为 77%-100%，并发症较少。在切除手术时进行初次种植已被证明是一种加速康复的有效方法，同时还有早期负荷方案。放射治疗在种植体失败中的作用尚未完全阐明，显然颧骨种植体可以成功用于放疗患者。报告的最常见用途是为上颌赝复体提供支持，无论是带支架的还是不带支架的种植体。
颧骨种植体为各种口腔和面部修复体提供了远程锚固，有助于改善接受上颌和中面部肿瘤治疗的患者的功能和生活质量。
