Thorough evaluation of dentition is important in the management of craniofacial trauma. Avulsed or fractured teeth in the pulmonary and gastrointestinal tracts can lead to serious complications that are well described. However, the penetration of avulsed teeth into soft tissues of the head and neck is unusual and may not be recognized. Two cases in which a tooth became a foreign body in these soft tissues are illustrative. One patient had bronchoscopy for possible aspiration of an avulsed maxillary canine; it was later found embedded in the premaxillary tissues. The other patient had a right mandibular molar propelled into the posterior triangle of the left side of the neck. Physicians must be aware of dental injury resulting from facial trauma and account for all teeth as part of their evaluation, keeping an open mind as to where a missing tooth might be located.
在颅面创伤的处理中，对牙列进行全面评估很重要。牙齿脱落在肺部和胃肠道或骨折可导致严重并发症，对此已有详细描述。然而，脱落的牙齿刺入头颈部软组织的情况并不常见，可能未被识别。有两例牙齿在这些软组织中成为异物的病例具有代表性。一名患者因可能吸入脱落的上颌尖牙而接受支气管镜检查；后来发现该牙嵌于前上颌组织中。另一名患者的右下颌磨牙被推进左侧颈部后三角区。医生必须意识到面部创伤导致的牙齿损伤，并在评估时将所有牙齿考虑在内，对缺失牙齿可能所在的位置保持开放的思维。
