Amplification by bone conduction in congenital malformations: patient benefits and satisfaction

Abstract

HA VO showed advantages for the population studied and should be considered as an option for intervention. Satisfaction was confirmed by elevated scores obtained in IQ - HA.

Vibrant Soundbridge and Bone Conduction Hearing Aid in Patients with Bilateral Malformation of External Ear

“…However, there is difficulty in the effective use of the bow due to the headaches caused by pressure arc on the mastoid and the negative psychosocial aesthetic impact of visible components of the hearing aid. 25 Thus, bilateral indication for surgery is a viable option for the study population.…”

Análise da percepção da fala com uso de dispositivos de amplificação em indivíduos com malformação de orelha e perda auditiva unilateral

“…The structures of the inner ear are usually normal in their development since they are originated from different embryonic tissues. (2) Hearing loss is one of the most common clinical findings in these cases, with type and degree varying according to the location of the malformation. (1) The assessment of auditory function in various spatial conditions is extremely important for choosing an appropriate treatment.…”

“…(6) Regarding amplification devices, the hearing aid aims to reestablish and improve the communicative function of the hearing impaired. (2) However, its adaptation is not always indicated due to the anatomical condition of the individuals in question. Thus, the use of bone conduction amplification devices becomes a valid option for individuals with such anomalies.…”

“…Thus, the use of bone conduction amplification devices becomes a valid option for individuals with such anomalies. (2) The use of bone conduction amplification devices aims to vibrate the cochlear structures without having to pass the acoustic stimulus through the structures of the outer and middle ears. The output transducer is a vibrator called a bone conductor.…”

“…For a correct transmission, the bone conductor is usually situated on one side in a band which uses elastic tension to press the bone conductor against the head. (2) The decision on the type of amplification to be used is up to the professional responsible for the case, together with the individual and their family members. The possibility of sound amplification by bone conduction is a practical, non-invasive and accessible option in some public services in Brazil.…”
