[Anaesthesia and spontaneous return of sensation following resection of the mandibular continuity with primary alloplastic materials].

Abstract

Resection affecting the continuity of the mandible and the mandible nerve leads to complete anaesthesia of the lower lip and mental area, furthermore to deformity and functional disturbance like uncontrolled salivation. In our long term follow up study on multimodal neurological investigation sensibility is reported to have uncomplete regenerated spontaneously often already after one year. Complete sensory, however, could not be found; the incomplete sensory return was to be measured in individually different degrees of hypaesthesia. Furthermore the axonal qualities of the mandible nerve show different regenerative potential: the receptor function for pressure and contact sensitivity could be demonstrated in the most of cases, whereas the heat- and painreceptor qualities could not be revealed in all cases.
