In 24 patients where the lower border of a cervical goitre was poorly defined, the value of simple lung function tests in the prediction of the presence of a retrosternal goitre was assessed. At operation there were nine patients with retrosternal extension (Group I) and 15 without (Group II). The preoperative PEF ratio (observed to predicted) was significantly different between the two groups (P = 0.004) with a positive predictive value of 90% for a retrosternal goitre. This difference was abolished after thyroidectomy. There was a significant improvement in PEF in patients with retrosternal goitres after thyroidectomy (P less than 0.001). It is concluded that the preoperative measurement of PEF is a simple method of detecting the retrosternal extension of a cervical goitre.
在24例甲状腺肿下缘界限不清的患者中，评估了简单肺功能测试对胸骨后甲状腺肿预测的价值。手术时，有9例患者存在胸骨后延伸（I组），15例没有（II组）。两组之间术前的呼气峰流速比值（实测值与预测值）有显著差异（P = 0.004），胸骨后甲状腺肿的阳性预测值为90%。甲状腺切除术后这种差异消失。胸骨后甲状腺肿患者甲状腺切除术后呼气峰流速有显著改善（P＜0.001）。结论是，术前测量呼气峰流速是检测甲状腺肿胸骨后延伸的一种简单方法。
