Four patients who had undergone combined surgical and radiotherapeutic treatment for maxillofacial cancer had osseointegrated titanium implants placed in the bone of the treated region at various intervals after irradiation. Preoperatively and postoperatively, hyperbaric oxygen therapy was administered to the patients at the level of 2 or 3 atmosphere absolute (ATA). Of the 21 fixtures placed, one was lost because of lack of osseointegration, rendering the survival rate 92.3%. Hyperbaric oxygen therapy seemed to be a viable method to improve the survival rate of fixtures in irradiated bone tissue.
4名接受过颌面癌联合手术及放射治疗的患者在放疗后的不同时间间隔，于治疗区域的骨内植入了骨整合钛种植体。术前及术后，对患者进行了2或3个绝对大气压（ATA）的高压氧治疗。在植入的21个种植体中，有1个因缺乏骨整合而丢失，种植体存活率为92.3%。高压氧治疗似乎是提高照射骨组织中种植体存活率的一种可行方法。
