title: [Intraesophageal pressure during esophageal speech in laryngectomized patients rehabilitated or no rehabilitated for oral communication].
abstract: BACKGROUND
  After laryngectomy for treatment of pharyngeal/laryngeal carcinomas the patients may be rehabilitated, for oral communication, with the esophageal speech.
  
  
  OBJECTIVE
  To study the intra-esophageal pressure during the esophageal speech.
  
  
  METHODS
  It was measured the intra-esophageal pressure in 25 laryngectomized patients aged 40 to 70 years (median 57 years), 10 rehabilitated with esophageal speech and 15 unable to do so. The manometric method with continuous perfusion was used. The esophageal pressures was measured 3 to 5 cm below the upper esophageal sphincter when the patients tried to speak the vowel "a". Sometimes the air swallowed went to the stomach, with a peristaltic or simultaneous contraction in the esophageal body.
  
  
  RESULTS
  During the attempt of esophageal speech the intra-esophageal pressure was higher in patients able to have esophageal speech (26.4 +/- 10.1 mm Hg, mean +/- SD) than in patients unable to do so (13.7 +/- 7.2 mm Hg). The esophageal contraction after a swallow of air was also higher in patients with esophageal speech (45.3 +/- 8.6 mm Hg) than in patients unable to do so (33.8 +/- 13.1 mm Hg).
  
  
  CONCLUSIONS
  Laryngectomized patients rehabilitated with esophageal speech has a higher intra-esophageal pressure during speech than patients unable to do so, what may be consequence of the capacity to retain air inside the esophagus.
