在上颌窦疾患手术中,常采用上颌窦前壁开窗以暴露手术野。然而,因上颌窦前壁骨质缺损,可能发生软组织向内增生窦腔闭合及瘢痕挛缩所致三叉神经痛等并发症。为此。骨质缺损的修复应引起重视。本研究应用CT评价带与不带骨膜蒂的骨瓣对上颌窦切开术骨愈合的影响。 选择20例患者,男8,女12,年龄25～60岁。其中牙根被挤入上颌窦13例,慢性上颌窦炎与口腔相通7例。随机分为两组,每组10例。组①采用无骨膜蒂的骨瓣,组②应用带骨膜蒂骨瓣。
In maxillary sinus surgery, often use the anterior wall of the maxillary sinus to expose the surgical field. However, due to the anterior osseous defect of the maxillary sinus, complications such as trigeminal neuralgia caused by closure of the sinus of the soft tissue inwards and scar contracture may occur. to this end. Repair of bone defects should be taken seriously. In this study, CT evaluation with and without periosteal pedicle flap on the maxillary sinus incision of bone healing. Select 20 patients, male 8, female 12, aged 25 to 60 years. The root was squeezed into the maxillary sinus in 13 cases, chronic maxillary sinusitis and oral communication in 7 cases. Randomly divided into two groups, 10 cases in each group. Group ① using boneless pedicle flap, group ② application of periosteal pedicle bone flap.
