| Popis: | Background: After laryngectomy, the tracheostoma forms the functional center for breathing and phonation. An occasionally occurring but typical problem can arise from an oversized and/or irregularly formed tracheostoma, hampering the temporary occlusion necessary for sufficient speech production. As an alternative to a surgical correction of the tracheostoma, an individually adjusted stoma silicone prosthesis may be used. Materials and Methods: Twenty-one patients suffering from irregularly formed tracheostoma after laryngectomy followed by insertion of a speech valve were provided with a silicone tracheostomal prosthesis. They underwent subjective assessment of voice quality and breathing function according to a standardized general questionnaire and to the Voice Handicap Index (VHI). Furthermore, a clinical evaluation was performed including detection of peristomal leakage and phonation time. Results and Discussion: Patients described a significant improvement of voice production with the tracheostomal prosthesis (averagely graded as 1.9 with and 3.2 without prosthesis, P = .0026). Breathing was also slightly improved by the prosthesis with an average grade of 1.7 compared to 2.3 with a conventional cannula ( P = .063). There was a strong correlation between self-evaluation and the total score of the VHI after insertion of the prosthesis ( P < .0001). Minor local skin reactions caused by the adhesive were described by 5 of the 21 patients. Conclusions: A tracheostomal prosthesis represents an efficient alternative to surgical revision of irregularly formed tracheostoma after laryngectomy, enhancing voice production and breathing function. |
