The influence of bone augmentation of the floor of the maxillary sinus for the insertion of dental implants on sinus function has not been well investigated. In this study, the influence of the sinus lift on the development of maxillary sinus pathology was evaluated using generally accepted diagnostic criteria.
A group of 45 patients in whom a sinus lift procedure had been performed were evaluated for sinus pathology 12 to 60 months after bone transplantation and implant insertion, using a questionnaire, conventional radiographic examination, and nasoendoscopy.
Postoperative maxillary sinusitis was detected in two of five patients with a predisposition for sinusitis, but in none of the other 40 patients. The occurrence of iatrogenic sinus membrane perforations during surgery was not related to the development of postoperative sinusitis in patients with healthy sinuses.
The occurrence of postoperative chronic sinusitis appears to be limited to patients with a predisposition for this condition. These predisposing factors need to be considered when evaluating patients for sinus lift procedures.
上颌窦底骨增量术用于植入牙种植体时对窦功能的影响尚未得到充分研究。在本研究中,使用普遍接受的诊断标准评估了上颌窦提升术对上颌窦病变发展的影响。
一组45例接受了上颌窦提升术的患者,在骨移植和种植体植入后12至60个月,通过问卷调查、传统影像学检查和鼻内镜检查评估鼻窦病变情况。
5例有鼻窦炎倾向的患者中有2例术后发生上颌窦炎,其他40例患者均未发生。手术中发生医源性窦膜穿孔与健康鼻窦患者术后鼻窦炎的发生无关。
术后慢性鼻窦炎的发生似乎仅限于有此倾向的患者。在评估患者是否适合进行上颌窦提升术时,需要考虑这些易感因素。
