The Blom-Singer valve is a device for facilitating speech in patients who have undergone total laryngectomy. The valve is inserted into a surgically created tracheo-oesophageal fistula. Fitting the valve and determining the correct length and direction of the fistula, although usually straightforward, can be difficult. We describe two patients in whom MR imaging of the fistula tract has aided valve fitting.
Blom-Singer瓣膜是一种用于帮助全喉切除术后患者发声的装置。该瓣膜插入通过手术形成的气管食管瘘中。安装瓣膜并确定瘘管的正确长度和方向，虽然通常很简单，但可能会有困难。我们描述了两名患者，其中瘘管的磁共振成像有助于瓣膜安装。
