  • variations in the origin of Superior Laryngeal Artery
    Anatomy & Cell Biology, 2016
    Co-Authors: Deepa Devadas, Minnie Pillay, Tintu Thottiyil Sukumaran
    Abstract:

    The Superior Laryngeal Artery is the principal Artery supplying the Laryngeal mucosa, musculature, and glands. Knowledge of variations in the origin of Superior Laryngeal Artery could prove to be very useful during reconstructive surgeries of the larynx, partial laryngectomy, Laryngeal transplantation, and also during procedures like super-selective intra-arterial chemotherapy for Laryngeal and hypoLaryngeal cancers. However, relatively few studies have been done on the Superior Laryngeal Artery in comparison to its clinical importance. The present study was aimed at documenting the prevalence of variable origin of the Superior Laryngeal Artery within the carotid triangle. Sixty hemi-necks obtained from 30 South Indian cadavers were dissected and studied for variations in the origin of Superior Laryngeal Artery. It was observed that the Superior Laryngeal Artery took origin from Superior thyroid in 91.7% cases. Variable origin from the external carotid Artery was noted in 5% cases. The Superior Laryngeal Artery was found to arise from the lingual Artery in one case alone (1.7%). In addition to the above findings, a very rare variation of Superior Laryngeal Artery arising from the ascending pharyngeal (1.7%) was also observed in the hemi-neck of one cadaver. All the variations that were observed were unilateral and on the left side. These findings may help provide further insight to the anatomists, radiologists and surgeons and can help improve performances during surgical manipulations of the larynx.

  • anatomical cadaver study of endoLaryngeal vascularization focus on the glottis supraglottis and subglottis from the transoral microsurgical point of view
    Frontiers in Oncology, 2018
    Co-Authors: Pietro Perotti, Marco Ferrari, Nausica Montalto, Davide Lancini, Alberto Paderno, Fabiola Incandela, Barbara Buffoli, Luigi Fabrizio Rodella
    Abstract:

    Introduction: Carbon dioxide laser coagulation during transoral laser microsurgery (TLM) for Laryngeal cancer allows control of bleeding from vessels smaller than 0.5 mm. Therefore, larger arteries and veins must be carefully managed by clipping and/or monopolar cautery. The aim of this paper is to detail endoLaryngeal vascular anatomy and identify areas of possible bleeding during TLM. Methods: We performed an anatomical study on a series of 11 fresh-frozen human cadavers. After injection of a bicomponent red silicone into the innominate, left common carotid, and left subclavian arteries, 22 hemilarynges were dissected, the course of the supraglottic, glottic, and subglottic vessels were traced after microdissection of the intervening structures, and their size measured at specific landmark points where such vessels are more frequently encountered during TLM. Results: Three vessels arising from the Superior Laryngeal Artery were identified after its entry point at the level of the thyro-hyoid membrane: 1) the epiglottic Artery (EA), documented in 100% of cases, and a common trunk dividing into two main vessels 2) the postero-inferior Artery (PIA), present in 100% of the specimens, running downward and dividing in a posterior (pPIA) and anterior (aPIA) branches 3) the antero-inferior Artery (AIA), present in 95% of our specimens, running downward to the anterior commissure (AC). Two transverse anastomotic networks (TANs) connected the AIA and PIA, both parallel to the vocal muscle, one lateral (present in 100% of cases), and another medial (91% of specimens). Finally, a fourth vessel supplying the glottic plane was found to be the endoLaryngeal paracommissural branch of the cricothyroid Artery (PCA), arising from the inferior Laryngeal Artery and emerging just below the AC, through the crico-thyroid membrane (reported in 100% of the specimens). This vessel anastomosed in 91% of cases with the AIA, through one or both of the TANs. Conclusion: The precise course of the endoLaryngeal arteries, their relationships with adjacent structures, and size at specific landmark points have been herein described in order to provide surgeons with a map to guide them during the steep learning curve of transoral surgery of the larynx, with special emphasis given to TLM.

  • Surgical anatomy of the internal branch of the Superior Laryngeal nerve
    European Spine Journal, 2006
    Co-Authors: Amac Kiray, Sait Naderi, Ipek Ergur, Esin Korman
    Abstract:

    The internal branch of the Superior Laryngeal nerve (ibSLN) may be injured during anterior approaches to the cervical spine, resulting in loss of Laryngeal cough reflex, and, in turn, the risk of aspiration pneumonia. Such a risk dictates the knowledge regarding anatomical details of this nerve. In this study, 24 ibSLN of 12 formaldehyde fixed adult male cadavers were used. Linear and angular parameters were measured using a Vernier caliper, with a sensitivity of 0.1 mm, and a 1° goniometer. The diameter and the length of the ibSLN were measured as 2.1±0.2 mm and 57.2±7.7 mm, respectively. The ibSLN originates from the vagus nerve at the C1 level in 5 cases (20.83%), at the C2 level in 14 cases (58.34%), and at the C2–3 intervertebral disc level in 5 cases (20.83%) of the specimens. The distance between the origin of ibSLN and the bifurcation of carotid Artery was 35.2±12.9 mm. The distance between the ibSLN and midline was 24.2±3.3 mm, 20.2±3.6 mm, and 15.9±4.3 mm at the level of C2–3, C3–4, and at the C4–5 intervertebral disc level, respectively. The angles of ibSLN were mean 19.6±2.6° medially with sagittal plane, and 23.6±2.6° anteriorly with coronal plane. At the area between the thyroid cartilage and the hyoid bone the ibSLN is the only nerve which traverses lateral to medial. It is accompanied by the Superior Laryngeal Artery, a branch of the Superior thyroid Artery. The ibSLN is under the risk of injury as a result of cutting or compression of the blades of the retractor at this level. The morphometric data regarding the ibSLN, information regarding the distances between the nerve, and the other consistent structures may help us identify this nerve, and to avoid the nerve injury.
