O uso do laser de baixa intensidade em indivíduos com zumbido e sem perda auditiva

Abstract

The use of Low Level Laser in individuals with tinnitus and without hearing loss Introduction: Among the most common complaints within otorhinolaryngology and audiology clinics, tinnitus stands out as one of the most uncomfortable for the subject. There are several modalities for the treatment of tinnitus, with emphasis on pharmaceutical therapy, physiotherapy, psychotherapy, surgery, and among the possibilities of intervention, there is growing significance in the use of low level laser. Nevertheless, despite many articles in the international literature about this theme, there are several disagreements regarding the protocol of application and the efficacy of this treatment. Proposition: To verify the effect of laser therapy in individuals with chronic tinnitus symptom without hearing loss. Methods: The study was developed at the Centro Auditivo Ouvir-Bauru, with the acceptance of the Research Ethics Committee and patient acquiescence confirmed by signing the Informed Consent Term. Patients who suited the inclusion criteria were randomly set to Group 1: treated with low level laser and Group 2: treated with placebo laser. Anamnesis was applied with the individuals before the battery of tests and the data collected were registered in the individual's folder. after the interview, the audiological exams started, which included: tonal audiometry, high frequency audiometry, immittanciometry and acufenometry for hearing loss disposal, Tinnitus Handicap Inventory to measure the level of discomfort with tinnitus pre and post treatment and visual analogue scale to measure the level of discomfort with tinnitus pre and post laser application. The Laser Therapy protocol included 12 laser therapy sessions for Group 1 and placebo laser for Group 2, using 4J in the lingual vein in the red wavelength, 4J in the right and left tympanic membrane, in the red wavelength, and 9J in the right and left mastoid, at the infra-red wavelength. Results: the sample consisted of 20 patients, eight females and 12 males with the average of 54 yearsold. There was no statistical difference in function of the intervention group and the moment of evaluation for the high frequency audiometry and acuphenometry outcomes. The disadvantage of individuals with chronic tinnitus reduced significantly after the intervention, regardless of the intervention. It can be verified that the annoyance of individuals with chronic tinnitus decreased significantly with difference between the initial and final sessions, independently of the intervention group, but Group 1 presented a greater reduction than Group 2, independently of the moment of evaluation and the number of the session. Conclusion: It was concluded that individuals with chronic tinnitus reduced the disadvantage independently of the intervention group, and the level of discontentment with tinnitus in the initial sessions according to the final ones independently of the moment of evaluation and the intervention group. The group receiving laser therapy further improved the level of tinnitus dissatisfact...

Laserterapia como recurso terapêutico na fonoaudiologia

“…Por meio dessa terapia evidencia-se a diminuição desse problema já nas primeiras sessões sendo que aqueles que recebem a fotobiomodulação apresentam melhoras no nível de insatisfação com o zumbido, independentemente do momento de avaliação e do número da sessão (Silva, 2019).…”

Therapeutic effects of photobiomodulation in the speech-language-hearing clinic: an integrative literature review

“…Speech-language-hearing therapists are increasingly interested in joining the group of professionals who use PBM, as it is a noninvasive and nontoxic therapeutic resource with promising results. Some studies have recently evaluated its results in speech-languagehearing rehabilitation in the fields ofAudiology and Oral-Motor Function and observed, respectively, reduced tinnitus 7 and improved electrical activity in the orbicularis oris muscle 8 .…”

Utilização do treinamento auditivo como intervenção para indivíduos com zumbido

“…O estudou conclui que apesar da LLLT propiciar redução da percepção do zumbido em alguns pacientes, no geral, não houve diferença significativa entre o grupo que recebeu a LLLT e o grupo placebo. Dentro deste mesmo contexto, quando analisada uma amostra de 20 indivíduos alocados em grupo placebo e grupo que recebeu a LLLT, observou-se redução significativa da desvantagem relacionada ao sintoma para ambos os grupos, mesmo que apenas o grupo que recebeu a irradiação apresentou maior diminuição da insatisfação com o zumbido quando comparado ao placebo(SILVA, 2019), desta forma, os grupos podem ter sofrido influência do efeito placebo no que diz respeito aos resultados positivos apresentados.Um estudo avaliou 43 pacientes com zumbido para analisar a eficácia da LLLT(NGAO et al, 2014). Os pacientes foram divididos em dois grupos: grupo que recebeu LLLT, com média de idade de 56,50 anos e grupo que não recebeu LLLT, com média de idade de 58,70 anos.…”
