BACKGROUND
The objective of the present study was to relate the dimensions and the intraluminal pressure of the pharyngoesophageal segment (PES) to the voice and speech proficiency of total laryngectomees with a tracheoesophageal prosthesis (TEP).
METHODS
Twenty total laryngectomees with secondary TEP insertion underwent evaluation of voice and speech, manometry, and videofluoroscopy.
RESULTS
Most laryngectomees (65%) were moderate speakers. The poorer speakers presented a lower intraluminal pressure in the PES at rest (4.44 mmHg) and a higher value (40.46 mmHg) during phonation. Good speakers presented a significant difference in the anteroposterior distance between prominence of the PES and the posterior pharyngeal wall (PPES-PPW) in the rest (6.09 mm) to phonation (3.24 mm).
CONCLUSIONS
The poorer speakers presented a lower intraluminal pressure in the PES at rest and a higher value during phonation compared with moderate speakers. Good speakers showed a significant difference in the PPES-PPW dimension.
背景
本研究的目的是将咽食管段（PES）的尺寸和腔内压力与带气管食管假体（TEP）的全喉切除术后患者的声音和言语能力联系起来。
方法
20 名接受二次 TEP 植入的全喉切除术后患者接受了声音和言语评估、测压和透视检查。
结果
大多数喉切除术后患者（65%）为中度发音者。较差的发音者在 PES 休息时的腔内压力较低（4.44mmHg），发音时的压力较高（40.46mmHg）。良好的发音者在 PES 突出部和后咽壁（PPES-PPW）在休息时（6.09mm）和发音时（3.24mm）之间的前后距离有显著差异。
结论
与中度发音者相比，较差的发音者在 PES 休息时的腔内压力较低，发音时的压力较高。良好的发音者在 PPES-PPW 尺寸上有显著差异。
