Abstract :

Osteoporosis is a multifactorial disease characterized by decrease in bone mineral density and

disruption of bony architecture. This reduction in bone mineral density is measured using T–score. T–score of ≥1 is normal, –1 to –2.5 is in the osteopenic range and ≤2.5 is in the osteoporotic range. There is lack of studies finding the relationship between osteoporosis and heå loss in Kashmiripopulation. The present study was undertaken to find the relation between heå loss and osteoporosis in postmenopausal Kashmiri women. Thirty postmenopausal Kashmiri women in the age range of 38–55 were subjected to bone mineral density (BMD) study and T–scores were obtained. Based on the T–scores, participants were divided into three groups. Group I consisted of 11 normal women, group II consisted of 10 osteopenic women and group III consisted of 9 osteoporotic women. Pure tone audiometry, tympanometry and distortion product otoacoustic emissions (DPOAEs) were carried out. Statistical analysis found that the mean threshold at all frequencies from 250 Hz to 8 kHz were better for normal, poorer for both osteopenic and osteoporotic group. At all frequencies the effect of reduced BMD on heå loss was significant.Results indicated that thresholds at all frequencies and pure tone average thresholds were significantly different between the three groups with p <0.05. ‘A’ type of tympanogram was present in all the groups. DPOAEs signal to noise ratio were significantly different at 3 kHz and 4 kHz between normal, osteopenic and osteoporotic group with p <0.05. However, there was no significant difference between the groups at 1 kHz and 2 kHz. Both osteopenic and osteoporotic group showed a greater number of individuals with sensorineural heå loss. The present study indicates a stronger relation between osteoporosis and heå loss. Effect of osteoporosis on auditory system using this test battery indicated bilateral sensorineural heå loss.
