Abstract

Purpose: The anatomy of the larynx and the knowledge of the possible variations in the laryngeal cartilages is important while interpreting head and neck radiographs of patients who exhibit anatomical or functional deviations. Morphometric data of the larynx may be useful in various otorhinolaryngology procedures and may also help in selecting the right dimensions of operational tools. Various studied have focused on the measurements of individual laryngeal cartilages. Very few authors have provided a holistic approach to the larynx and their values vary considerably. Therefore this study aims at providing appropriate information regarding the various laryngeal measurements thereby contributing to the field of advanced medicine. Methods: The study was performed on 25 sagittal sections of adult larynges (14 males, 11 females) in the department of Anatomy, Kasturba Medical College, Manipal. The different parameters of the larynx were measured using digital calipers. Appropriate statistical tests were applied. Results: The morphometric measurements of the larynx were more in males as compared to females. However females had a larger cricoid diameter. Conclusion: The study therefore opines that there is a significant difference in dimensions of larynges in males and females. The dimensions of larynx and internal cricoid diameter may act as a reliable guide for various interventions involving the upper respiratory passages.

Abstract

Amaç: Yapısal veya fonksiyonel deviyasyon gösteren hastaların baş ve boyun radyograflarını değerlendirirken, larinksin anatomik yapısı ve laringeal kıkırdakların muhtemel çeşitlerinin bilinmesi önemlidir. Larinksin morfometrik bilgisinin bilinmesi, çeşitli otorinolaringoloji prosedürlerinde faydalı olabilir ve operasyonda kullanılacak araçların boyutunun doğru seçimine de yardım edebilir. Çeşitli çalışmalar bireysel laringeal kıkırdak ölçümüne odaklanmıştır. Çok az yazar larinkse bütünsel bir yaklaşım göstermektedir ve değerleri önemli ölçüde farklılık göstermektedir. Bu yüzden bu çalışma, çeşitli laringeal ölçümlere ilişkin uygun bilgi sağlamayı böylece ileri tıp alanına katkı sağlamayı amaçlamaktadır. Materyal ve Metod: Bu çalışma Manipal, Kasturba Tıp Fakültesi, Anatomi Bölümünde yetişkin (14 erkek 11 kadın) larinkslerinde 25 sagital bölme üzerinde uygulandı. Larinkste farklı parametreler dijital kumpas kullanılarak ölçüldü. Uygun istatistiksel testler yapıldı. Bulgular: Kadınlara nazaran erkeklerde larinksin morfometrik ölçümleri daha fazlaydı. Ancak kadınlar daha geniş bir krikoid çapına sahiplerdi. Sonuç: Dolayısıyla bu çalışmaya göre kadınlar ve erkekler arasında larinks boyutu bakımından anlamlı bir farklılık vardır. Larinksin ve iç krikoid çapının boyutları, üst solunum yollarınıda içeren müdahaleler için güvenilir bir rehber olarak kullanılabilir.
