MORPHOMETRIC DIMENSIONS OF FETAL LARYNX
Author: Mamatha H., Vinodhini P., Suhani S., Prasanna L.C., Antony Sylvan D souza
Introduction: The laryngeal cavity space extends from the laryngeal inlet down to the lower border of the cricoid cartilage, where it continues as the trachea. The skeletal framework is formed by a series of cartilages interconnected by ligaments and fibrous membranes. The vocal cords are the primary source of phonation. The larynx contributes for indispensable significance from embryologic, anatomic, physiologic and surgical standpoints. Aim: The aim of the present study was to investigate morphometric growth patterns of the cartilaginous components and vocal cords in fetal larynx. Materials and methods: The study was done on 25 spontaneously aborted (13 males and 12 females) fetuses from second to eighth month, in the Department of Anatomy, Kasturba Medical College, Manipal. The fetuses were obtained from the Department of Gynecology, Kasturba Medical Hospital, and Manipal. Results: The dimensions of the larynx and its cartilaginous components were measured and the relationship between the obtained data was statistically assessed. Conclusion: Correlations were found between the cartilaginous components, size of the larynx, and gestational age. Advances in neonatal medicine have resulted in increased care of fetal and neonatal airways, which requires an exhaustive knowledge of fetal airway anatomy and development .This study results are useful in the prenatal analysis, during treatment planning of airway emergencies and while designing supra glottis devices.
