Outcome Measures of Facial Nerve Regeneration: A Review of Murine Model Systems.

Outcome Measures of Facial Nerve Regeneration: A Review of Murine Model Systems. Ann Anat. 2019 Aug 05;: Authors: Chacon MA, Echternacht SR, Leckenby JI Abstract Animal models of nerve function have been subject to extensive study in order to understand and investigate methods which may improve axon regeneration and promote functional outcomes following nerve injury and repair. As the facial nerve is a cranial nerve, there is mounting evidence that cranial nerve regeneration differs from peripheral, and outcome models specifically addressing the facial nerve are required. Murine models are the most commonly utilized, with a variety of methods employed to measure the actions of whisking, eye closure, or ear movement as indicators of facial nerve regeneration. Each method of measurement is reviewed in terms of validity, strengths, limitations, and the specific outcome data provided. The authors propose that prior to choosing an outcome model, the goals and objectives of a planned study should be well defined, as various outcome measures may be useful depending on the information which is desired. The aim of this paper, therefore, is to provide the reader with a concise review which may facilitate project design. PMID: 31394169 [PubMed - as supplied by publisher]
