[Biofeedback therapy in patients with dysphonia and benign laryngeal pathology after endolaryngeal interventions].

OBJECTIVE

To increase the effectiveness of voice restoration in patients with benign organic laryngeal pathology and functional dysphonia after endolaryngeal interventions.

MATERIAL AND

METHODS

360 patients who underwent surgery for benign organic pathology of the vocal folds were examined. The examination was performed using videolaryngoscopy, videolaryngostroboscopy, computer acoustic analysis of the voice, and a subjective assessment of vocal function by a doctor on the N. Yanagihara scale.

RESULTS

In 58 patients in the postoperative period, after the relief of inflammatory phenomena, the voice did not recover, due to the pathological type of phonation: nodular, hypotonic or hypertonic. Voice restoration measures were carried out: phonotherapy for patients of the 1st group, phonotherapy and biofeedback therapy sessions for patients of the 2nd group. According to subjective and objective assessments, biofeedback therapy significantly accelerated voice recovery in patients with hypertonic phonation. Biofeedback therapy had no significant effect on the restoration of vocal function in patients with nodular and hypotonic phonation.

CONCLUSION

In cases where the voice does not fully recover after endolaryngeal interventions, additional therapeutic measures are required: phonotherapy and biofeedback therapy.
