Thirty-nine laryngectomized patients from the Professorial Unit of The Royal National Throat, Nose and Ear Hospital, London, were recalled between 6 months and 18 years after operation. The tracheal and stomal diameters were measured and, in addition to a full general examination, respiratory function tests (including arterial blood gas estimations) were performed. Most patients had impaired respiratory function tests which were in excess of the expected impairment due to age alone. The study suggests that impaired function is due to intercurrent pulmonary and cardiovascular diseases, rather than anatomical factors related to the changed upper airway. There was no correlation between stomal size or tracheal/stomal cross sectional area ratio and the measured respiratory function.
来自伦敦皇家国立耳鼻喉医院教授病房的39例喉切除患者在术后6个月至18年被召回。测量了气管和造口直径，除了进行全面的常规检查外，还进行了呼吸功能测试（包括动脉血气分析）。大多数患者的呼吸功能测试结果受损，这种受损程度超过了仅因年龄增长所预期的程度。该研究表明，功能受损是由于并发的肺部和心血管疾病，而非与上呼吸道改变相关的解剖学因素。造口大小或气管/造口横截面积比与所测呼吸功能之间无相关性。
