下颌骨节段性切除术后,双侧下牙槽神经(IAN)损伤常常导致下唇和牙龈感觉丧失。该文作者旨在报道下颌骨节段切除联合放化疗后,采用血管化神经移植重建双侧IAN,利用腓骨肌皮瓣联合腓肠神经重建下颌骨。采取端端吻合方式将腓肠神经的近、远心端分别缝合于左、右两侧的IAN残端。颏神经残端采用端侧吻合缝合于腓肠神经。Semmes-Weinstein After mandibular segmental resection, bilateral inferior alveolar nerve (IAN) damage often leads to a loss of sensation in the lower lip and gums. The authors aim to report the reconstruction of bilateral IAN with vascularized nerve grafts after mandibular segmentectomy combined with chemoradiation and to rebuild the mandible using the fibula myocutaneous flap combined with the sural nerve. The proximal and distal ends of the sural nerve were sutured to the left and right IAN stumps respectively by end-to-end anastomosis.
