摘　　要：舌神经损伤是牙槽外科中较为严重的并发症之一,往往发生在下颌第三磨牙(M3M)拔除术后,发病率约0.1%~22%。由于临床检查及传统影像学检查的局限性,部分重症患者在损伤发生早期未得到准确诊断和有效治疗,导致舌神经永久性损伤,大大影响生活质量。近年来,磁共振神经成像(MRN)技术逐渐用于神经损伤的检查中,多种新型磁共振成像序列对重度舌神经损伤均有很好的显像,使舌神经损伤的早期诊断及治疗成为可能。本文报道了1例拔牙所致舌神经损伤2周的患者,通过磁共振检查可见舌神经完全离断样损伤。随后进行了神经吻合术,术中观察到舌神经完全离断,证明磁共振影像与现实相符,术后随访显示舌神经功能逐步恢复。Lingual nerve injury is one of the serious complications in alveolar surgery,which often occurs after the extraction of the mandibular third molar(M3M),with the incidence varying from 0.1%to 22%.Due to the limitations of clinical and conventional radiographical examinations,some severe cases do not receive accurate diagnosis and effective treatment in the early stage of injury,resulting in permanent lingual nerve injury and consequent impact on the quality of life.In recent years,magnetic resonance neurography(MRN)has been gradually used in the examination of nerve injury,and several new MRN sequences have reasonable visualization of severe lingual nerve injury,making early diagnosis and therapy possible.This article reported a patient with lingual nerve injury caused by the removal of M3M for 2 weeks,and complete disconnection of the affected lingual nerve was clearly visualized through MRN.Subsequently,a nerve anastomosis surgery was performed,and the disconnection was observed during the operation,proving the consistency of the MRN imaging and the fact.Postoperative follow⁃up showedgradually functional recovery of the lingual nerve.
