laryngeal reinnervation by ansa cervicalis nerve implantation for unilateral vocal cord paralysis in humans
Journal of The American College of Surgeons, 2007Co-Authors: Wanfu Su, Hsinchien Chen, Hwa ShengAbstract:Background Ansa cervicalis (AC)–recurrent laryngeal nerve anastomosis (RLN) is usually not desirable for correction of paralytic dysphonia when it is difficult to find a viable distal stump of the recurrent laryngeal nerve. Nerve implantation of the thyroarytenoid muscle with the ansa cervicalis is a simple alternative method. Study design Ten patients with unilateral vocal cord paralysis were prospectively designed to receive nerve implantation. A minimum period of 12 months after onset of paralysis was allowed to elapse to permit possible spontaneous reinnervation or compensation. Patients were followed long enough (at least 2 years) to determine if the procedure was successful. All patients were subjected to preoperative and postoperative voice recording, acoustic analysis, and videolaryngoscopy. Some of them underwent laryngeal electromyography. Results Ten patients underwent nerve implantation of the thyroarytenoid muscles by using the ansa cervicalis, and 8 of 10 (80%) had improved phonatory quality. Laryngeal electromyography showed that the procedure produced satisfactory reinnervation of the thyroarytenoid muscle. Conclusions Nerve implantation of the thyroarytenoid muscle by the anso cervicalis is a simple and efficient alternative to nerve transfer if dense scarring at the Cricothyroid Articulation and lack of a viable distal stump of the recurrent laryngeal nerve preclude the procedure of nerve transfer. But careful selection of the appropriate candidate seems to be the earliest prerequisite for a successful procedure.

Ann Orol Rhinal Laryngo1114:2005 ANATOMY OFTHE Cricothyroid Articulation: DIFFERENCES BETWEEN MENAND WOMEN
2016Co-Authors: Roxo Aragao Ximenes Filho, S C Bohadana, Phd Andrei Felix A PerazzioAbstract:A greater difficulty in exposing the arytenoid cartilage during rotation surgeries has been observed for men. The objective of the present study was to describe the position of the Cricothyroid Articulation and the distance between the right and left Articulations, and to compare these findings between genders. The following measurements were obtained for 16 cadavers (9 men and 7 women): angulation of the Cricothyroid Articulation in the cricoid ring, dimensions of the thyroid articular surface of the cricoid cartilage, and distance between the Cricothyroid and cricoarytenoid Articulations. The Cricothyroid Articulation angle was narrower in men than in women (p =.04). The major diameter of the articular facet of the thyroid cartilage was wider in men (p =.001). The longer lamina of the thyroid cartilage, as well as the more posterior position of the Cricothyroid Articulation, in men might explain the greater difficulty in exposing the arytenoid cartilage during laryngeal framework surgeries observed for this group of patients. KEY WORDS- anatomy, arytenoid cartilage, Cricothyroid Articulation, gender difference, laryngeal framework surgery
