Abstract

Background: Rima glottidis and cricoid cartilage are important parts for laryngeal
passage. However, their complex anatomical organizations give rise to occur
some difficulties during intubation or surgeries. Therefore, these anatomical
structures have great risk of damage during these procedures. The main aim of
this study is to evaluate detailed morphometric properties of these critical
parts of the larynx.

Methods:
In this study, 74 female and 76 male patients’, without any pathology in their
laryngeal and neck regions, computed tomography images were examined,
retrospectively. Anteroposterior diameter of the supraglottic region
immediately above the vocal folds, anterior angle of the vocal folds,
transverse diameter of the rima glottidis and anteroposterior and transverse
diameters of the cricoid cartilage were measured using Osirix-Lite version 9.

Results:
Transverse diameter of the cricoid cartilage was found less than 1 cm, however,
the transverse diameter of the rima glottidis was significantly smaller. All
variables except for anterior angle of the vocal folds were higher in men than
women.

Conclusions: The transverse diameter of the rima glottidis was the narrowest part
of the laryngeal passage. The physicians should be aware of this part of the
larynx besides the cricoid cartilage during endotracheal tube
administrations.

Abstract

Amaç: Rima glottidis ve cartilago cricoidea larynx geçişinin önemli
kısımlarıdır. Bununla birlikte, karmaşık anatomik yapılar olmaları sebebiyle
entübasyon veya cerrahi sırasında bazı güçlüklere yol açabilirler. Bu sebeple,
bu işlemler sırasında, bu anatomik yapılar, istenmeyen yaralanmalar açısından
oldukça büyük bir risk altındadırlar. Çalışmamızın amacı, larynx’in bu önemli
parçalarının morfometrelerinin detaylı olarak incelenmesidir.

Materyal ve
Metod: Bu çalışmada, larynx ve
boyun bölgelerinde herhangi bir patoloji olmayan 74 kadın ve 76 erkek hastaya
ait bilgisayarlı tomografi görüntüleri retrospektif olarak incelendi. Plica
vocalis’in hemen üzerinde kalan supraglottic bölgenin anteroposterior çapı,
plica vocalis’lerin anterior birleşme açısı, rima glottidis’in transvers çapı
ve cartilago cricoidea’nın anteroposterior ve transvers çapları Osirix-Lite
version 9 yazılımı kullanılarak ölçüldü.

Bulgular: Cartilago cricoidea’nın transvers çapı 1 cm'den az bulundu, ancak rima
glottidis'in transvers çapı cartilago cricoidea’nın transvers çapından anlamlı
derecede daha küçüktü. Plica vocalis’in anterior açısı dışındaki tüm
değişkenler erkeklerde kadınlardan daha yüksekti.

Sonuç: Rima glottidis’in transvers çapı larynx geçişinin en dar kısmıydı.
Endotrakeal tüp uygulamaları sırasında, uygulamayı yapacak olan hekimler
cartilago cricoidea’nın yanı sıra larynx’in bu kısmının da farkında olmalıdır.
