Predictive value of esophageal motility test in the proficiency of esophageal speech

Quality of life among total laryngectomized patients undergoing speech rehabilitation: correlation between several instruments

OBJECTIVE

The aim of this study was to correlate several instruments currently used for the assessment of the quality of life of patients who underwent total laryngectomy and speech rehabilitation.

METHODS

A cross-sectional, observational study was conducted with 38 patients after total laryngectomy and speech therapy aiming to develop oesophageal speech. The patients were divided into the following two groups (19 participants each): speakers and non-speakers. The quality of life instruments used were as follows: visual analogue scale (VAS); Voice Handicap Index (VHI); Voice-Related Quality of Life (V-RQOL); Functional Assessment of Cancer Therapy - Head & Neck (FACT-H&N); European Organisation for Research and Treatment of Cancer Core Quality of Life Questionnaire (EORTC QLQ-C30); European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Head and Neck (EORTC QLQ-H&N35); and University of Washington Quality of Life (UW-QOL).

RESULTS

The V-RQOL global health domain exhibited a strong correlation with the VHI. The EORTC QLQ-C30 exhibited a moderate to strong correlation with the EORTC QLQ-H&N35 functional domain in both groups. The EORTC QLQ-C30 functional domain exhibited a strong to moderate correlation with all other instruments in both groups. The UW-QOL exhibited a moderate to strong correlation with the VHI and EORTC QLQ-C30 in both groups.

CONCLUSION

The EORTC QLQ-C30, EORTC QLQ-H&N35 and UW-QOL were the instruments that most correlated with the remaining instruments, indicating that any of the three can be used to assess the quality of life of the target population regardless of oesophageal voice development.

Electrophysiological activity of the pharyngoesophageal transition of total laryngectomees

OBJECTIVES/HYPOTHESIS

To determine the association of the electrophysiological activity of the pharyngoesophageal transition with tracheoesophageal speech proficiency in total laryngectomees.

STUDY DESIGN

An observational (nonexperimental) study of the correlation type with a descriptive approach.

METHODS

Thirty-four individuals (26 males), average age 62.5 years, total laryngectomees rehabilitated with the use of a tracheoesophageal prosthesis, were assessed for tracheoesophageal speech proficiency using an adapted protocol and classified as good, moderate, or poor speakers. Next they were submitted to electromyography of the muscles of the pharyngoesophageal transition with a needle electrode. The area to be examined was located by videofluoroscopy. Electromyographic analysis was characterized as normal, neurogenic injury (moderate to severe, severe, severe to total), myopathic injury, or inconclusive. The Fisher exact test was used to determine the association between the speech proficiency variables and electromyography.

RESULTS

in the final rating of tracheoesophageal speech proficiency, most laryngectomees were categorized as moderate (n = 24) and a few as good (n = 3). Electromyography revealed neurogenic injury in all laryngectomees, which was severe in most cases (n = 20), followed by severe to total (n = 10), and moderate to severe injury (n = 4). There was no significant association between he electromyographic analyses of neurogenic injuries and tracheoesophageal speech proficiency.

CONCLUSIONS

Whether or not the musculature of the pharyngoesophageal transition of tracheoesophageal speakers had a preserved motor unit, did not prevent voice acquisition and was not associated with tracheoesophageal speech proficiency. However, further studies are needed in this area.
