Association Between Location of Nasopharyngeal Carcinoma, Pre- and Postradiation Therapy Otitis Media With Effusion, and Sensory Neural Hearing Loss

A new instrument for the detection of the postauricular myogenic (PAM) response was used to test the hearing of 106 infants weighing ≤1,500 g when they were aged 1 to 21 months. Eighty-eight infants showed a positive response at 60 dB hearing level (HL) (normal). The other 18 did not respond; four were found to have sensory neural hearing loss and another six had conductive loss due to secretory otitis media. Of the 106 children, 90 aged 2 years or more (mean 27 months) were living in the United Kingdom, and their language development was assessed. It was normal in 67/75 children whose PAM response had been normal in infancy. The remaining eight children with normal PAM responses in infancy, had language delay. All eight children had problems that were thought to account for the delay, including three with mental retardation, three with cerebral palsy, and two whose families did not speak English. Language development was normal in 11/15 children tested whose PAM responses had been found to be abnormal, including all six whose secretory otitis media had been diagnosed and treated at the time of the PAM test. Delay in language development was found in 3/4 children with sensory neural hearing loss who were available for testing and in one child with overall developmental delay. It is concluded that a positive PAM response at 60 dB HL in infancy indicated hearing adequate for the development of normal speech in otherwise normal children among a group of infants at high risk of hearing loss.

Background: The role of chronic inflammatory disease of the middle ear as a cause of sensory neural hearing loss (SNHL) is still debatable. Therefore, the role of this study to see if there is a relation between SNHL and duration of chronic supportive otitis media (CSOM), socio-economic (SE) status and age of patient.Methods: The hospital based case series study was conducted on all CSOM patients coming to ENT out-patient department in S. Nijalingappa Medical College and Hanagal Shri Kumareshwar (HSK) Hospital, Bagalkot, Karnataka over a period of one and a half years. After clinical examination, hearing evaluation was done using PTA as main tool.Results: Based on the present study, overall proportion of patients with SNHL was 20.66%. No relation of SNHL was found between sex and SE status of patient. No relation was found between severity of SNHL and age of patient. No relation was found between severity of SNHL and duration of CSOM. This present study shows that patients with CSOM with increased age have a greater chance of developing SNHL. Also, as the duration of CSOM increases there is a greater chance to develop SNHL.Conclusions: This study shows that the chance of developing SNHL in CSOM increases with age and disease duration. Hence, we can conclude that CSOM should be treated appropriately as early as possible to reduce the risk of developing SNHL in patients with CSOM.
