To assess the long-term recovery of sensation in the lower lip after mandibular resection without reconstruction of the inferior alveolar nerve.
Thirty patients who had mandibular resection carried out without reconstruction of the inferior alveolar nerve were examined after an interval ranging from 6 to 33 years.
Only 1 patient, seen 10 years after resection, was totally numb over the distribution of the inferior alveolar nerve. The other 29 patients had some return of sensation and many had a significant return, though it may take several years to reach the final result. Utilizing the MRC scale 70% of patients achieved S3 (return of superficial cutaneous pain and tactile sensibility without over response) CONCLUSION: This study can serve as a baseline for comparison with patients who have had mandibular resection with reconstruction of the inferior alveolar nerve to assess if this procedure improves the outcomes.
评估下颌骨切除后不重建下牙槽神经时下唇感觉的长期恢复情况。
对 30 名接受了不重建下牙槽神经的下颌骨切除术的患者进行了检查，随访时间为 6 至 33 年。
只有 1 名患者在切除后 10 年时完全丧失了下牙槽神经分布区的感觉。其余 29 名患者的感觉有一定程度的恢复，许多患者的感觉恢复明显，尽管可能需要数年时间才能达到最终结果。利用 MRC 量表，70%的患者达到 S3（浅表皮肤痛觉和触觉恢复，无过度反应）。
本研究可作为与接受下颌骨切除和重建下牙槽神经的患者进行比较的基线，以评估该手术是否改善了结果。
