title: [Quality of life and voice handicap of laryngectomees using tracheoesophageal substitute voice].
abstract: BACKGROUND
  Health-related quality of life (QoL) and subjective health have become popular constructs for the evaluation of both efficacy and efficiency of diagnostic and therapeutic procedures in medicine. QoL is considered a multidimensional construct encompassing physical, mental and social facets of life. It is an accepted outcome parameter not only in international classification systems such as ICIDH and ICF, but as well in clinical guidelines and disease management programs. Measuring quality of life allows for comparison of different diseases though it certainly lacks disease specific aspects. Thus, it has to be assumed that in patients with distinct functional deficits QoL cannot cover all aspects that are important for the individual patient. This study focuses on laryngectomies and their self-evaluation of post-laryngectomy speech. It is well known that these patients experience a decreased QoL compared to patients after partial laryngectomy or healthy persons. In this study, the impact of voice restoration on the laryngectomies' QoL was evaluated.
  
  
  METHODS
  In 20 male laryngectomies aged 62 +/- 8 years, relations between QoL and voice handicap were evaluated using two instruments as proposed in the international literature, i. e. the Short-Form Health Survey (SF-36) and the Voice Handicap Index (VHI). All patients had successfully been using tracheoesophageal substitute voice for at least one year. Complete data sets were available from all patients. Data were analysed using Microsoft Excel and Sigma Plot, Jandel Corp. software packages.
  
  
  RESULTS
  Results of both the SF-36 and the VHI reveal wide interindividual ranges. There are statistically significant correlations (p < 0.05) between the SF-36's scales General Health and Vitality and the VHI, whereas no correlations were found between social and psychological scales and the voice handicap.
  
  
  CONCLUSIONS
  Wide ranges of the data obtained reveal that obviously both health related quality of life and voice handicap are not affected in a group specific way. So, both tests are of clinical value to depict individual aspects of wellbeing after laryngectomy. The combination of VHI and SF-36 illuminates correlations between general and special subjective aspects. Strikingly, the laryngectomies' social and psychological status is not related to their voice handicap. Data allow for conclusion that laryngectomies' substitute voice problems do not affect social aspects of quality of life in a disease specific way, at least as long as voice restoration was successful at all.
