Vascularized transplantation of the long thoracic nerve for sensory reinnervation of the lower lip

Microsurgical techniques have improved functional and morphological reconst ruction of the face in recent years. An important factor is the re-establis hment of neuronal function. The aim of this study was a follow-up of the re generation of sensation in the inferior alveolar nerve after partial resect ion of a tumour and reconstruction with a vascularized long thoracic nerve graft. Five patients were examined in monthly intervals to assess the degre e of re-establishment of sensation. Pressure and pain responses were elicit ed as early as three months postoperatively, sense of touch and vibration w ere found after five months, and sensitivity to temperature after seven mon ths postoperatively. In four patients nine months postoperatively, sensory qualities in the region of the mental nerve were identical on both sides. T he vascularized long thoracic nerve is therefore an adequate nerve graft fo r covering defects as a result of resection of the inferior alveolar nerve patients with tumours.
