Stage III and IV cancers of larynx and hypopharynx often require total laryngectomy which leaves the patient with severe communication handicap. In such laryngectomised patients tracheo-esophageal puncture is the best way for voice rehabilitation using either Blom-Singer® prosthesis or Provox® indwelling valve.
A prospective comparative study of Blom-Singer® prosthesis and Provox® indwelling valves placed in Tracheo-esophageal Punctures (TEP) for voice rehabilitation following total laryngectomy was carried out at the Tata Memorial Hospital, Mumbai and Malignant Diseases Treatment Centre of Armed Forces, to assess their efficacy. This report comprises of our experience in 41 (39 males and two females) laryngtectomees who underwent TEP of which 15 patients were fitted with low pressure Blom-Singer® prostheses and 26 with Provox® indwelling prostheses.
Prostheses related problems like granuloma formation, leakage, candidal growth over the valves and prosthetic decay were significantly less in the patients fitted with Provox® prosthesis. Dislodgement of prosthesis with closure of the tract or persistent fistula formation and creation of false passage, while reinsertion were problems encountered in the Blom-Singer group. After three months, speech assessment revealed a better quality of voice production and patient compliance in maintaining the prosthesis in the case of Provox® indwelling valve.
In Indian scenario where illitracy amongst the patients hinders in maintainence of Blom-Singer® prosthesis, Provox® indwelling value is an appropriate choice for voice rehabilitation.
Ⅲ期和Ⅳ期喉癌及下咽癌通常需要进行全喉切除术,这会给患者带来严重的交流障碍。在这类喉切除患者中,气管食管穿刺是使用Blom-Singer®假体或Provox®留置瓣膜进行语音康复的最佳方法。
在孟买的塔塔纪念医院和武装部队恶性疾病治疗中心,对全喉切除术后用于语音康复的气管食管穿刺(TEP)中植入的Blom-Singer®假体和Provox®留置瓣膜进行了一项前瞻性对比研究,以评估其疗效。本报告包含了我们对41例(39例男性和2例女性)接受TEP的喉切除患者的经验,其中15例患者安装了低压Blom-Singer®假体,26例安装了Provox®留置假体。
安装Provox®假体的患者中,假体相关问题如肉芽肿形成、渗漏、瓣膜上念珠菌生长和假体腐烂明显较少。Blom-Singer组遇到的问题包括假体移位伴通道闭合或持续性瘘管形成以及再插入时假通道的形成。三个月后,语音评估显示,对于Provox®留置瓣膜,语音质量更好,患者在维持假体方面的依从性更高。
在印度,患者的文盲状态阻碍了Blom-Singer®假体的维护,Provox®留置瓣膜是语音康复的合适选择。
