最近16年里,我科在下颌阻生智齿劈开拔除中,先后有5例牙齿掉入咽旁间隙内,为吸取经验教训,现报道于后:本组5例中除1例为左下智齿低位前倾倒生外,其余4例均为低位水平阻生智齿。2例于牙齿坠入咽旁间隙后,立即切口,寻找掉入牙,发现掉入牙距表面深达2～2.5公分,分别历时40及50余分钟将坠入的牙齿摘除。其余3例均经下颌骨侧位片证实,牙齿确已脱出牙槽窝,井位于牙槽窝底部的后下方,重叠于下颌枝前下部。虽然术中试图摘除,但因触动已浮悬于软组织中的牙齿继续下沉,故终止手术。2例终难避免在拔牙伤口后内方形成瘘管,溢脓。术后,患者自诉咽部肿胀,隐痛不适,
In recent 16 years, our department in the mandibular impacted wisdom teeth split removal, there have been 5 cases of teeth fall into the parapharyngeal space, in order to learn the lessons learned, are reported after: In this group of 5 cases, except 1 case of the lower left wisdom teeth Low down before dumping, the remaining four cases were low levels of impacted wisdom teeth. 2 cases of teeth fall into the parapharyngeal space, immediately incision, looking for dropped teeth and found falling into the surface of the teeth as deep as 2 to 2.5 cm, respectively, which lasted 40 and 50 minutes will be removed from the teeth. The remaining three cases were confirmed by the lateral mandibular films, the teeth indeed out of the alveolar fossa, well in the lower part of the bottom of the alveolar nest, overlapping the mandibular branch before the lower part. Although intraoperative attempts to remove, but because the touch has been floating in the soft tissue of the teeth continue to sink, so the termination of surgery. 2 patients eventually difficult to avoid the formation of fistula in the tooth extraction wound, overflow pus. After surgery, patients complained throat swelling, pain and discomfort,
