title: [Tracheal stenosis following direct laryngoscopy].
abstract: The appearance of progressive and disabling dyspnoea in a 58 year old lady, beginning three months after direct laryngoscopy (LD) led to a pulmonary function assessment after six months of mistaken diagnoses. The flow/volume (V/V) curves were characteristic of a high fixed obstruction. Fibreoptic endoscopy showed a non-neoplastic stenosis by a sub-glottic diaphragm. The stenosis was treated in a lasting fashion using a Yag laser (Medilas 2). Other than a congenital stenosis presenting in adulthood, the only cause that can be considered is a traumatic stenosis (post-LD) on an inflamed larynx. Such an aetiology for tracheal stenosis has never, to our knowledge, been described. Even if this type of stenosis is extremely rare, the possibility should not be ignored.
