13. Evaluation of Functional Outcomes after Stapes Surgery in Patients with Clinical Otosclerosis in a Teaching Institution
Introduction Otosclerosis is a primary disease of the temporal bone that leads to stapes ankylosis. Hearing loss is the main symptom. Treatment includes surgery, medical treatment, and sound amplification therapy alone or in combination. Objective To evaluate the functional outcomes of patients with clinical diagnosis of otosclerosis undergoing primary s

14. Active Bone Conduction Prosthesis: BonebridgeTM
Introduction Bone conduction implants are indicated for patients with conductive and mixed hearing loss, as well as for patients with single-sided deafness (SSD). The transcutaneous technology avoids several complications of the percutaneous bone conduction implants including skin reaction, skin growth over the abutment, and wound infection. The Bonebridge

16. A comparative in vivo ultrasonometric evaluation of normal and delayed fracture healing in sheep tibiae
OBJECTIVE: To compare normal and delayed bone healing by measuring ultrasound conduction velocity across the bone callus. METHODS: A model of transverse linear and 5 mm resection osteotomies of sheep tibiae was used. Fourteen sheep were operated on and were divided into two groups of seven according to osteotomy type. The procedure was performed on the rig

17. Results of the implantation of bone-anchored hearing aids in patients with treacher-collins syndrome
INTRODUCTION: Treacher-Collins syndrome is characterized by craniofacial malformations, narrowing of the external auditory canal (EAC), and, in 30% of cases, agenesis of the canal and ossicular chain defects. The use of hearing aids (HA) is not possible in cases in which agenesis or stenosis of the EAC accompanies conductive deafness. In contrast, bone condu

18. Limiares eletrofisiológico e psicoacústicos por via óssea em indivíduos normais e com perda auditiva. / Electrophysiological and psychoacoustic thresholds bone in normal hearing impaired
To investigate the electrophysiological thresholds obtained by bone and compared them with the psychoacoustic thresholds obtained in pure tone audiometry in adults with normal hearing and with different types and degrees of hearing loss. Methods: The sample consisted of 70 subjects, 35 men and 35 women (30 normal, 10 with conductive hearing loss, 10 with mil

19. Avaliação audiológica em pacientes com mucopolissacaridose: estudo da ocorrência, tipo e grau de perda auditiva / Audiological evaluation in mucopolysaccharidosis: study of the occurrence, type and degree of hearing loss
Purpose: the mucopolysaccharidosis are a group of diseases caused by a deficiency in the lysosomal enzymes involved in the metabolism of mucopolysaccharides. Inherited metabolic diseases are caused by inborn errors of metabolism that lead to lack of proper functioning of certain enzymes. Hearing loss is a frequent manifestation in patients with mucopolysacch

20. Bone conduction measurements in normal hearing subjects: acoustic radiation and bone vibrator positioning / Medida da condução óssea em sujeitos ouvintes normais: radiação acústica e posicionamento do vibrador ósseo
Clinical audiology literature and practice raise questions about bone conduction assessment results. The most common questions are related to the reliability of bone conduction thresholds as they suffer a lot of artifacts that may mislead the results obtained. Silman &Silverman (1997) describe two important factors that could interfere in such measurement: a

21. POTENCIAL EVOCADO AUDITIVO DE TRONCO ENCEFÁLICO POR CONDUÇÃO ÓSSEA EM NEONATOS
Bone Conduction Auditory Brainsterm Response is the most appropriate technique to access the cochlear reserve of newborns without the influence of any conductive component. It is a practical, accurate and noninvasive instrument for the differential diagnosis of conductive, mixed or sensorineural hearing loss. The purpose of this study was to investigate the

22. Mascaramento clínico: limiares auditivos pelos métodos Platô e Otimizado
INTRODUCTION: Many situations may difficult the obtaining of thresholds for each ear, separately, in pure tone audiometry, demanding the use of masking. The plateau method, developed by Hood (1960) has being the most utilized for more than four decades. Nevertheless, Turner (2004) has suggested a masking protocol with a different method, called optimized, wh

24. POTENCIAL EVOCADO AUDITIVO POR CONDUÇÃO ÓSSEA EM PACIENTES COM MICROSSOMIA CRANIOFACIAL
Microssomia Craniofacial é uma síndrome congênita que envolve estruturas derivadas do primeiro e do segundo arcos-branquiais, com deformidade no osso temporal -processo mastóide, orelha externa e base do crânio, podendo acarretar perda auditiva. É orelha média, comumente encontrada unilateralmente, mas também pode ser observada bilateralmente. O obje
