“…That is in accordance to previous anatomical studies 8,15 . However, the oblique line did not seem to be a good anatomical reference to identify TAb, as suggested by other authors 8 . As demonstrated in Table 2, although most laryngeal measures (Ln, TAb-H and TAb-V) presented with fairly good symmetry between sides, the same did not occur with Obl, suggesting that the oblique line does not hold a constant relation with other laryngeal dimensions.…”

“…The TAb lies deep to the thyroid cartilage and the anatomy related to its surgical approach is not well known. Few studies describe the anatomy of the intralaryngeal portion of the inferior laryngeal nerve [3][4][5][6][7][8] , but the relation of TAb to anatomical landmarks of the thyroid cartilage is still poorly described.…”

Brazil. Scientific, intelectual, conception and design of the study; manuscript preparation; critical revision; final approval. ABSTRACT PURPOSE:To describe the anatomical course of the intralaryngeal portion of the inferior laryngeal nerve (ILN) and to standardize the surgical access to its thyroarytenoid branch (TAb) through the thyroid cartilage. METHODS:Under surgical microscopy, 33 adult human excised larynges were dissected, to expose the intralaryngeal portion of ILN. The point of entry of TAb, ILN's terminal branch, in the thyroarytenoid (TA) muscle was determined and correlated with thyroid cartilage dimensions. RESULTS:After entering the larynx, the ILN consistently traveled between the thyroid cartilage and the lateral cricoarytenoid muscle in an anterior and slightly cranial course. The distance from the point of entry of the TAb in the TA muscle to the midline (TAb-H) and to the inferior border (TAb-V) of the thyroid cartilage differed according to gender. In females, mean distances of TAb-H and TAb-V were 20.5mm and 5.2mm and in males, 22.3mm and 5.9mm, respectively. CONCLUSION:The intralaryngeal course of the inferior laryngeal nerve presents low variability and measures from landmarks in the thyroid cartilage help to estimate the point of entry of thyroarytenoid branch in thyroarytenoid muscle.

“…To facilitate measurement of the nerve and its branches, two different thyroid cartilage windows were performed: a standard posterior window as described by Netterville and Billante 23 and an inferior window as described by Scheid et al 24 Neither of these provided adequate exposure for measurement and thus later, the CT joint was transected and the posterior portion of the thyroid cartilage was removed. The cut was positioned at the posterior limit of the inferior thyroid tubercle.…”

“…Scheid et al dissected 13 human larynges (24 sides) and measured the distance between the inferior thyroid tubercle to the TA branch along a perpendicular line from the inferior thyroid tubercle on the inferior border of the thyroid cartilage . The distance of the TA branch from the inferior thyroid tubercle was found to be in the range of 1 to 4 mm, the median distance being 3.75 mm.…”
