Anatomical variations of the external branch of the superior laryngeal nerve in relation to the inferior constrictor muscle
The Journal of Laryngology & Otology, 08/20/2012
Patnaik U et al. – The prevalence of type 3 variation of the external branch of the superior laryngeal nerve suggests that the nerve will not be encountered in a certain percentage of individuals as it lies under the cover of the inferior constrictor. Therefore, there is no justification for attempting to identify the nerve in all cases.
