To document accurately the tracheo-oesophageal party wall thickness (PWT) intra-operatively in patients undergoing total laryngectomy and to correlate it with constitutional parameters like height, weight, body mass index (BMI), age, and gender. Also, to correlate PWT with the length of tract (LOT), that is prosthesis size, as measured using the standard valve length measuring device provided by the manufacturers.
Twenty-eight patients of carcinoma larynx, following removal of the diseased larynx had their tracheo-oesophageal PWT measured using a special custom-designed and calibrated external (or outside) calliper and a primary trachea-oesophageal puncture (TOP) was made and inserted 10-14 days postoperative with an appropriately sized Blom-Singer(R) indwelling voice prosthesis.
The mean PWT was 3.1 mm. PWT showed significant correlation with the weight of the patients (P = 0.006). There was no significant correlation between PWT and height, BMI, age or gender of the study group. The average LOT was found to be 4.8 mm (SD 1.5). There was a significant correlation (P = 0.009) between PWT and initial LOT, with the most commonly used prosthesis sizes being 4-6 mm.
The study shows that Indian patients with a thin party wall require a smaller prosthesis size and it is advisable to measure the PWT intra-operatively. Tracheo-oesophageal PWT in laryngectomised patients in India: implications for surgical voice restoration.
准确记录行全喉切除术患者的气管食管吻合处（PWT）壁厚度，并将其与身高、体重、体重指数（BMI）、年龄和性别等体质参数相关联。此外，还将 PWT 与使用制造商提供的标准阀长度测量装置测量的管腔长度（LOT）（即假体尺寸）相关联。
对 28 例喉癌患者，在切除患病的喉部后，使用特殊定制和校准的外部（或外部）卡尺测量其气管食管 PWT，并在术后 10-14 天进行初次气管食管穿刺（TOP），插入适当尺寸的 Blom-Singer（R）留置嗓音假体。
平均 PWT 为 3.1 毫米。PWT 与患者体重呈显著相关性（P = 0.006）。PWT 与研究组的身高、BMI、年龄或性别无显著相关性。平均 LOT 为 4.8 毫米（SD 1.5）。PWT 与初始 LOT 之间存在显著相关性（P = 0.009），最常使用的假体尺寸为 4-6 毫米。
该研究表明，印度薄壁患者需要较小的假体尺寸，建议在手术中测量 PWT。印度喉切除患者的气管食管 PWT：对手术嗓音恢复的影响。
