The pharyngoesophageal high pressure zone (PE-HPZ) was measured prelaryngectomy and postlaryngectomy with a new force-summing probe that accounts for sphincter pressure asymmetry. A total of 31 patients were studied six times each. Postoperatively, pressures dropped from 130+/-24 mm Hg to 66+/-9 mm Hg. After a standardized, intensive laryngectomy rehabilitation program, 12 of 19 postoperative patients acquired acceptable esophageal speech and 7 did not. Speakers and nonspeakers were found to have nearly identical PE-HPZ pressures (speakers = 70+/-10 mm Hg, nonspeakers = 59+/-18 mm Hg). Differences in sphincter length or relaxation likewise did not discriminate between these two groups. We conclude that PE-HPZ pressure is not a critical determinant of the acquisition of esophageal speech.
使用一种新的力总和探头在喉切除术前和术后测量咽食管高压区（PE-HPZ），该探头可考虑括约肌压力不对称情况。总共对31例患者进行了6次研究。术后，压力从130±24毫米汞柱降至66±9毫米汞柱。经过标准化的强化喉切除术后康复计划，19例术后患者中有12例获得了可接受的食管语音，7例未获得。发现能够说话者和不能说话者的PE-HPZ压力几乎相同（能够说话者 = 70±10毫米汞柱，不能说话者 = 59±18毫米汞柱）。括约肌长度或松弛程度的差异同样无法区分这两组。我们得出结论，PE-HPZ压力不是获得食管语音的关键决定因素。
