Noisy breathing sound due to obstruction of the pharynx
Medical condition
Stertor (from Latin stertere 'to snore') and first used in 1804,[2] is a noisy breathing sound like snoring .[3] [4] It is caused by partial obstruction of the upper airways , at the level of the nasopharynx or oropharynx .[1]
It is distinguished from stridor by its pitch.[4] Stertor is low-pitched, and can occur when breathing in , out or both.[5] Stertor and stridor can occur together, such as when adenotonsillar hypertrophy and laryngomalacia occur together.[5]
