Anatomical dimensions of larynx, epiglottis and cricoid cartilage in foetuses and their relationship with crown rump length

Background Advances in perinatal care and increased use of diagnostic and interventional procedures on foetal airway demand a clear understanding of their normal anatomy and development. This study is aimed at determining the normal dimensions of larynx, cricoid cartilage and epiglottis and their correlation to age and crown rump length (CRL).
