Inclusion criteria
Inclusion criteria: 1. Submitted to total laryngectomy 2. Rehabilitated with voice prosthesis 3. With tracheoesophageal voice 4. With and without spasm 5.

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Evaluation of a cutoff value for diagnosis of spasm of pharyngo-oesophageal segment (PES) with computerised manometry (CM) or PES in total laryngectomy (TL) patients. In the group without spasms, outcomes were measured after selection criteria were established. In the group with spasms, after the requirements of selection criteria were fulfilled, the patients were selected and all measurements were done. Then treatment with botulinum toxin was done and after one month of application of toxin all measurements were repeated. | — |
Secondary
| Measure | Time frame |
|---|---|
| 1. Evaluation of degree of statistical difference of mean values of computerised manometry between patients with and without spasm 2. Evaluation of improvement of fluency of speech in patients with spasm after application of botulinum toxin in pharyngo-oesophageal segment In the group without spasms, outcomes were measured after selection criteria were established. In the group with spasms, after the requirements of selection criteria were fulfilled, the patients were selected and all measurements were done. Then treatment with botulinum toxin was done and after one month of application of toxin all measurements were repeated. | — |
