The neck circumference of cases with Type 2aEBSLNs was less than that of those with Type 2b EBSLNs (p=0.005).Conclusions: The relationships that we have identified may aid surgeons to identify the EBSLN.

🎯
Objective & Hypothesis:Objectives/Hypothesis: The aim of this study was to investigate whether a relationship was evident between variations of the externalbranch of the superior laryngeal nerve (EBSLN) and the recurrent laryngeal nerve (RLN) and neck circumference in adult cadavers.Methods: Bilateral neck dissections were performed on 42 cadavers (84 sides); 31 males and 11 females with a of mean age 56.48 ±10.10 years.
📊
Key Findings & Data:EBSLNs were classified using the system proposed by Cernea et al. and RLNs were classified in terms of their relationship tothe inferior thyroid artery.Results: We found statistically significant associations between EBSLN and RLN Types.

Abstract

Objectives/Hypothesis: The aim of this study was to investigate whether a relationship was evident between variations of the externalbranch of the superior laryngeal nerve (EBSLN) and the recurrent laryngeal nerve (RLN) and neck circumference in adult cadavers.Methods: Bilateral neck dissections were performed on 42 cadavers (84 sides); 31 males and 11 females with a of mean age 56.48 ±10.10 years. EBSLNs were classified using the system proposed by Cernea et al. and RLNs were classified in terms of their relationship tothe inferior thyroid artery.Results: We found statistically significant associations between EBSLN and RLN Types. EBSLN Type 2b was significantly morecommon in patients with type B RLNs compared with type A RLNs (p=0.015) and type C RLNs (p=0.037). Also, EBSLN Type 2a wassignificantly more common in patients with type A RLNs compared with type C RLNs (p=0.018). We found no significant associationbetween EBSLN or RLN Type and neck circumference, except for Type 2a and 2b EBSNs. The neck circumference of cases with Type 2aEBSLNs was less than that of those with Type 2b EBSLNs (p=0.005).Conclusions: The relationships that we have identified may aid surgeons to identify the EBSLN.

Özet

Giriş: Bu çalışmada erişkin kadavralarda superior laringeal sinirin eksternal dalı (SLSED) ve rekürren larengeal sinir (RLS) varyasyonları ve boyun çevresi arasında bir ilişki olup olmadığının araştırılması amaçlanmıştır. Gereç ve Yöntem: 42 kadavrada (84 taraf) boyun diseksiyonu yapıldı; 31 erkek ve 11 kadın kadavranın ortalama yaşı 56.48 ± 10.10 yıl idi. SLSED Cernea ve ark. tarafından önerilen sistem kullanılarak, RLS'ler inferior tiroid arter ile olan ilişkileri açısından sınıflandırıldı. Bulgular: SLSED ve RLS tipleri arasında istatistiksel olarak anlamlı ilişkiler bulduk. Tip 2b SLSED, tip B RLS'li hastalarda anlamlı olarak daha yaygın idi. Ayrıca, Tip 2a SLSED, tip A RLS'li hastalarda daha fazla bulundu (p = 0.018). Tip 2a ve 2b SLSED'ler haricinde, SLSED veya RLS tipi ve boyun çevresi arasında anlamlı bir ilişki bulamadık. Tip 2a SLSED olan olguların boyun çevresi, Tip 2b SLSED olanlardan daha düşüktü (p = 0.005). Sonuç: Bu çalışmada tanımladığımız ilişkiler cerrahların SLSED'nı identifiye etmesine yardımcı olabilir.
