BACKGROUND Chronic suppurative otitis media (CSOM) is one of the leading causes of preventable disabling hearing impairment (DHI) in developing countries. Early detection and management complements advances made in other survival programs, improves work capacity, and enhances learning opportunities for school children. We aimed to determine the prevalence of CSOM and associated DHI among school...
The monitoring of anaesthetic depth is usually based on the subjective assessment of the patient. An objective assessment of anaesthesia has only recently become possible. The auditory-evoked response has predictable changes in response to increasing doses of anaesthetic agents. Recent advances have brought about a regression model with exogenous input of the auditory-evoked response, the A-lin...
Cholesteatoma is an epidermoid cyst that is characterized by independent and progressive growth with destruction of adjacent tissues, especially the bone tissue, and tendency to recurrence. Treatment of cholesteatoma is essentially surgical. The choice of surgical technique depends on the extension of the disease, and preoperative otoscopic and radiological findings can be decisive in planning ...
BACKGROUND Streptococcus pneumoniae [Sp] infection is associated with local and systemic disease. Our current understanding of the differential contributions of genetic strain variation, serotype, and host response to disease phenotype is incomplete. Using the chinchilla model of otitis media [OM] we investigated the disease phenotype generated by the laboratory strain TIGR4 and each of thirtee...
INTRODUCTION Etiopathogenetically, there are two types of chollesteatomas: congenital, and acquired. Numerous theories in the literature try to explain the nature of the disease, however, the question about cholesteatomas remain still unanswered. The aim of the study was to present a case of external ear canal cholesteatoma (EEC) developed following microsurgery (ventilation tube insertion and ...
OBJECTIVES Mastoid obliteration is used to obliterate the mastoid cavity following a mastoidectomy or to prevent the formation of a retraction pocket. This study evaluated the effectiveness of β-tricalcium phosphate and polyphosphate (β-TPP) for mastoid obliteration in middle ear surgeries in prospective human and animal studies. METHODS Twenty patients with chronic otitis media underwent mas...
INTRODUCTION This study sets out to determine the usefulness of a questionnaire to screen for hearing impairment, assess the psychosocial impact of hearing handicap and survey older persons' attitudes towards hearing aid usage. METHODS Subjects were recruited from a Geriatric Medicine unit over a six-month period. A questionnaire was administered, followed by an otoscopic examination and audi...
BACKGROUND & OBJECTIVE Hearing impairment is one of the associated problems seen particularly in children with cleft palate rather than cleft lip alone. This has received very little attention in the area of cleft care although research shows that hearing impairment affects language development The present study was carried not to find out the type and pattern of audiogram in cases attending a ...
OBJECTIVE We investigated whether preeclampsia is a risk factor for cochlear damage and permanent hearing loss. STUDY DESIGN Prospective case-control study design. SETTING Academic tertiary medical center. PATIENTS Subjects included 40 patients with preeclampsia and 30 healthy pregnant women. INTERVENTIONS Otoscopic examinations and pure-tone audiometry, tympanometry, otoacoustic emissi...
BACKGROUND Acute otitis media (AOM) is one of the most common forms of bacterial infection and cause for clinic visits in children. The incidence of AOM was 0.9-1.2 episodes per person-year during the first 2 years of life in previous reports conducted before 2000. The aim of this study was to 1) evaluate the latest AOM incidence in pediatric outpatients and 2) identify the bacterial pathogens ...
