Treatment for Vocal Polyps: Lips and Tongue Trill

SummaryVocal polyps do not have a well-defined therapeutic indication. The recommended treatment is often laryngeal microsurgery, followed by postoperative speech therapy. Speech therapy as the initial treatment for polyps is a new concept and aims to modify inappropriate vocal behavior, adjust the voice quality, and encourage regression of the lesion. This study aimed to determine the effectiveness of the sonorous lips and tongue trill technique in the treatment of vocal polyps. The sample consisted of 10 adults diagnosed with a polyp who were divided into two subgroups: treatment and control. Ten speech therapy sessions were conducted, each lasting 30-45 minutes, based on the sonorous lips and tongue trill technique, accompanied by continuous guidance about vocal health. Speech therapy was effective in three of the five participants. The number of symptoms presented by the participants decreased significantly after voice therapy (P = 0.034) and vocal self-evaluation (P = 0.034). The acoustic evaluation showed improvements in parameters of noise values (P = 0.028) and jitter (P = 0.034). The size of the polyp and the degree of severity of dysphonia, hoarseness, and breathiness showed a significant reduction after treatment (P = 0.043). Among the remaining two participants, one opted out of laryngeal surgery, indicating that the improvement obtained was sufficient to avoid surgery. The sonorous lips and tongue trill technique was thus considered effective in 60% of the participants, and as laryngeal surgery was avoided in 80% of them, it should be considered a treatment option for vocal polyps.
