Cadaveric study of cricothyroid space - Anatomical perspective

Dr. Parmanand Agarwal, Dr. Yuvaraj J Bhosale

Abstract :

Cricothyroid space is the indentation between the thyroid and cricoids cartilages and is covered by the anterior/median cricothyroid ligament, a useful site for emergency access to the airway. The aim of the present study was to collect data on the cricothyroid space in Indian population by measuring the height & width of the cricothyroid space and also measure anterior length of larynx. Sixty apparently healthy looking specimens were obtained from embalmed cadavers. Height of cricothyroid space ranged from 6.64 - 12.56 mm, Transverse width of cricothyroid space ranged from 9.8 – 18.9 and length of larynx in anterior midline ranged from 27.12 - 42.96 mm. understanding of the dimensions and crucial anatomy of the cricothyroid space and related area is important to avoid or manage complications during surgical cricothyroidotomy. The dimensions are variable in different population, there is scope for more such study to corroborate these findings and its clinical relevance.
