在某些患有喉部纖維化或是狹窄的病人身上，以仰臥方式往往難以達到理想的喉部手術視野。在本報告中我們呈現一喉部嚴重纖維化的喉部手術病患，我們發現將病患的姿勢由仰臥改為俯臥將可以大幅度的改善所需要的喉部手術視野，在可能的狀況下醫師可以善加利用重力以爭取處理困難手術時的有利條件。

In patients who suffer from laryngeal fibrosis or stenosis, the usual retraction and exposure for laryngeal surgery is unsatisfactory. We demonstrate a trans-nasal fiberoscopic laryngeal laser surgery on a patient suffering from bilateral vocal fold paralysis and laryngeal stenosis due to previous irradiation for hypopharyngeal cancer. The laryngeal surgical field under the nasopharyngoscope in both the supine and the prone positions was recorded and compared. The result demonstrates that in some circumstances, setting the patient in the prone position may facilitate laryngeal surgery and whenever possible, gravity can be used to facilitate a difficult procedure.
