The associated facial asymmetry can contribute to social isolation. Facial nerve reconstruction using a combination of interposition nerve grafts and\/or nerve transfers offers significant improvement. However, these options are limited by insufficient donor nerves and unwanted synkinesis if a single donor nerve is used for the entire hemi-face. To ameliorate both limitations, we perform an ansa cervicalis to marginal mandibular nerve transfer to restore tone and symmetry to the lower third of the face. We have found this a safe and feasible technique with minimal donor site morbidity. The anatomy is favorable both in terms of donor nerve length and size match between nerves. We report 9 cases with at least 6 months follow up which demonstrate improved lower lip tone and symmetry and improved oral competence. Early donor site morbidity and postoperative complications are minimal. This method is a reliable adjunct in facial nerve reconstruction to address the marginal mandibular nerve paralysis.<\/jats:p>","DOI":"10.1177\/22925503251386749","type":"journal-article","created":{"date-parts":[[2025,10,30]],"date-time":"2025-10-30T17:41:28Z","timestamp":1761846088000},"page":"768-773","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Ansa Cervicalis to Marginal Mandibular Nerve Transfer, a Feasible Option to Improve Lower Lip Function in Facial Nerve Paralysis"],"prefix":"10.1177","volume":"34","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8384-5970","authenticated-orcid":false,"given":"Marieta","family":"Van der Vyver","sequence":"first","affiliation":[{"name":"University of Calgary"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0000-4267-9363","authenticated-orcid":false,"given":"Eva","family":"Lindell-Jonsson","sequence":"additional","affiliation":[{"name":"University of Calgary"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kristin N.
