Morphological and functional asymmetry of the human recurrent laryngeal nerve

Abstract: If length and latency asymmetry of the right and left RLNs in humans can be demonstrated, the synchronicity of the vocal folds requiring precise controlled variations within intrinsic laryngeal muscles needs further investigations.

“…Prades and colleges performed a cadaveric study and identified the mean lengths of the left and right recurrent laryngeal nerves to be 136.6 and 75.0 mm, respectively. The mean difference in length between the two recurrent laryngeal nerves was 61.6 mm (range, 50–75 mm) . Although not statistically significant, mean latency measurements performed using vagal stimulation (0.5 mA, 1.0 mA) intraoperatively in 10 patients showed a mean difference between the right and left thyroarytenoid muscles of 3.55 to 3.68 and 5.90 to 5.98 ms, respectively .…”

“…Changes in the emotional status can lead to an increased pain perception [17]. We can state that the diaphragm has an influence on baroreceptors, perception of pain and emotional state [24]. The action of the diaphragm is not only controlled by metabolic factors, but also by emotional states such as sadness, fear, anxiety, and anger.…”

“…Es importante recordar que el nervio laríngeo recurrente es predominante- Tasa global de sección operatoria: 0,64 % Tasa de lesión inadvertida: 0,13 % mente motor somático, se origina en la porción inferior del núcleo ambiguo del nervio espinal, alcanza el vago y se une a él en su porción intracraneal antes de su salida por el agujero yugular; en su porción terminal inerva los músculos intrínsecos de la laringe junto con la rama interna del nervio laríngeo superior, constituyendo el asa laríngea de Galeno que permite la fonación; además, mantiene la vía aérea permeable durante la deglución y la respiración, e inerva la mucosa laríngea por debajo de los pliegues vocales [7][8][9] . En su trayecto hacía la laringe, el nervio laríngeo recurrente tiene múltiples variaciones anatómicas.…”
