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.
