Abstract

Two cases of non-fatal airway obstruction by nasal secretions are described. The diagnosis was made after laryngoscopy and the features which suggested this previously undescribed aetiology were: depression of conscious level: poor oral hygiene; and irregular friable mass with mucoid areas obstructing the airway. The diagnosis was confirmed by histological examination of the obstructing material which was composed of laminated fragments of squamous epithelium, keratin debris and mucus. It is suggested that these masses form in the post-nasal space and then become dislodged descending into the larynx, where they cause partial laryngeal obstruction and stridor.

In patients whose conscious level is depressed and who have poor oral hygiene, nasal secretions should be considered as a cause of sudden unexplained airway obstruction and stridor.
