Multiple semicircular canal dehiscences are clinical entities characterised by vestibular and cochlear symptoms induced by enhanced sensitivity of labyrinthine receptors due to a multiple bone defect of the otic capsule. The case is presented of a 38-year-old male with bilateral posterior semicircular canal dehiscence associated with unilateral (right) superior semicircular canal dehiscence. Th...

Results: Audiometric evaluation showed a maximal unilateral left conductive hearing loss. High resolution temporal bone CT showed absence of the oval window on the left along with facial and stapes abnormalities. Exploratory tympanotomy showed an aberrant facial nerve, monopodal and abnormally located stapes and absent oval window. Postoperative hearing gain achieved after a neo-oval window and...

In this issue, we have an interesting review article by Dr. Mario Zernotti and his team in Cordoba on the Bonebridge bone conduction implant. Bone conduction implants are indicated for patients with conductive, mixed, or unilateral hearing loss. The transcutaneous technology employed avoids common complications such as cutaneous reactions, skin covering the abutment, local infection, or extrusi...

Patients with unaidable sensorineural hearing loss in one ear and normal hearing in the opposite ear can present a challenge to audiologists. At least two recommendations may be available. One approach is to attempt to minimize the communication problems associated with unilateral hearing loss by recommending preferential seating or counseling the patient to place the normal ear so it faces the...

Etoposide and ifosfamide are chemotherapeutic agents used frequently in the treatment of sarcomas and hematologic malignancies. Ocular side effects are rarely reported. We describe a case of a patient on etoposide and ifosfamide who presented with unilateral vision loss, anemia, and thrombocytopenia. The patient was found to have a large subinternal limiting membrane hemorrhage in the right eye...

INTRODUCTION AND OBJECTIVES Assess the improvement of quality of life in osseointegrated implanted patients, taking into account the indication as well as the use of the implant, and the presence of pre- and postoperative tinnitus. METHODS Sixty-nine patients implanted between June 2004 and November 2010 were included. The average age of the patients was 40 years. The instruments used to quan...

We assessed ultrasonic transmission in a dry skull; in a dry skull with water, simulating the living condition; in a cadaver head; and in six human subjects, one of whom exhibited no measurable hearing. By using these preparations, we concluded that fluid conduction is essential in the propagation of sound across the head, whereas the bone pathway is far less effective in that regard. Thus, the...

o bjectives: the aim of the present randomized clinical trial was to evaluate marginal bone loss around two types of implants modified at the neck area: nobel active and nobel replace groovy, both manufactured by nobel biocare. materials and methods: a total of 25 nobel active and 21 nobel replace groovy implants were included in the present study. the implants were placed based on the relevant...
