Preoperative assessment of the central airway is concerned primarily with the detection and evaluation of laryngotracheal stenosis. There are many causes of laryngotracheal stenosis; however, stenosis secondary to a thyroid goitre is one of the more common types requiring evaluation prior to general anaesthetic. A postero-anterior chest and lateral thoracic inlet radiograph have been the primary investigative tools used to assess the degree of tracheal compression and deviation in both the transverse and antero-posterior planes.1 In many patients this type of imaging will suffice; however, computed tomography (CT) will more comprehensively detail the extent of tracheal stenosis and the degree of retrosternal extension. Compression of other structures by retrosternal
