Abstract
Anatomical restoration was once the only goal of reconstructive surgery, but now it represents only one step in the complete functional recovery process to allow resumption of physiological activity. Soft tissue and nerves play important roles in functional recovery, but the potential of these structures is not yet well known. Rehabilitation after oral cavity reconstruction by free flaps needs an interdisciplinary diagnostic and therapeutic approach, in which neurosensory recovery of transferred tissue is an important aspect.Previous studies have used clinical assessment to evaluate sensory recovery after oral reconstruction with free flaps, but these results have been subjective and not quantifiable. The aim of the present study is to evaluate the sensory recovery using objective and standardized electrophysiological data by recording the masseter inhibitory reflexes (MIR) following mental and lingual electrical stimulation.A group of 14 patients who underwent oral cavity reconstruction by transplantation of either forearm (9) or jejunal (5) noninnervated free flaps were investigated. We found that sensory recovery of fasciocutaneous radial forearm free flaps was better than that of jejunal free flaps. This could represent the starting point for further studies about sensory recovery of reconstructed anatomical structures based on standardized and objective electrophysiological data.
