Drug-induced sleep endoscopy represents the \u2018gold standard\u2019 in identifying the obstruction site, from the palatal level to laryngeal entry. Breathing impairment in sleep caused by the collapse of cervical trachea after previous tracheostomy has not yet been described in the literature.<\/jats:p><\/jats:sec><jats:sec id=\"S0022215119001166_sec_a2\" sec-type=\"methods\"><jats:title>Methods<\/jats:title><jats:p>This report presents two patients with severe obstructive sleep apnoea, in whom pre-operative drug-induced sleep endoscopy revealed upper airway and cervical trachea collapse at the level of previous tracheostomy.<\/jats:p><\/jats:sec><jats:sec id=\"S0022215119001166_sec_a3\" sec-type=\"results\"><jats:title>Results<\/jats:title><jats:p>The female patient was successfully treated with resection of hypertrophic tissue of the tongue base via lateral pharyngectomy, and resection of the collapsed segment of the trachea with primary reconstruction of the trachea by end-to-end anastomosis.
