The ansa cervicalis nerve (ACN) is an advantageously situated donor with great potential but has not been examined in detail. In the current study, the anatomical technical feasibility of selective ACN to marginal mandibular nerve (MMN) transfer for restoration of lower lip tone and symmetry was explored. A clinical case is presented.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Dissections were conducted in 21 hemifaces in non\u2010embalmed human cadavers. The maximal harvestable length of ACN was measured and transfer to MMN was simulated. A 28\u2010year\u2010old male underwent ACN\u2010MMN transfer after parotidectomy (carcinoma) and was evaluated 12\u2009months post\u2010operatively (modified Terzis' Lower Lip Grading Scale [25 observers] and photogrammetry).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The harvestable length of ACN was 100\u2009\u00b1\u200912\u2009mm. A clinically significant anatomical variant (\u201cshort ansa\u201d) was present in 33% of cases (length: 37\u2009\u00b1\u200912\u2009mm). Tensionless coaptation was possible in all cases only when using a modification of the surgical technique in \u201cshort ansa\u201d cases (using an infrahyoid muscle nerve branch as an extension). The post\u2010operative course of the clinical case was uneventful without complications, with improvement in tone, symmetry, and function at the lower lip at 12\u2010month post\u2010operative follow\u2010up.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Selective ACN\u2010MMN nerve transfer is anatomically feasible in facial paralysis following oncological ablative procedures.
