Description

A conduit for peripheral nerve regeneration (Nerbridge®) in cases with disconnection or deficiency of the peripheral nerve was approved in Japan in 2013. The use of Nerbridge has been reported mainly in orthopedic surgery, and its efficacy in trials was 82.8%. We report two cases of lingual nerve reconstruction using Nerbridge. In both cases, the lingual nerve was resected due to submandibular gland cancer. We evaluated the cases by the Semmes-Weinstein monofilaments test. In the 1-year postoperative evaluation, the results were 4.17 Fm (purple) and 4.56 Fm (red), and the sensory nerve had recovered. There are problems with length restriction and price, but it is one of the effective reconstruction methods for reconstruction of the lingual nerve.
