The combination of a narrow oesophageal lumen and a hypertonic pharyngo-oesophageal (P-E) segment following laryngectomy and secondary tracheo-oesophageal puncture (TEP) can cause obstruction of a voice prosthesis and consequently prevent phonation. The 'Allan Johnson' modification of the Bivona voice prosthesis incorporates a stainless steel slide and has been successfully used to remedy such a circumstance.
喉切除术后继发气管食管穿刺(TEP)时,狭窄的食管腔与高渗性咽喉-食管(P-E)段相结合,可导致语音假体阻塞,从而妨碍发声。Bivona语音假体的“艾伦·约翰逊”改良型包含一个不锈钢滑片,并已成功用于改善这种情况。
