Audiometric Test with a Smartphone

This retrospective study examines the relationship between auditory steady-state evoked potential (ASSEP) thresholds determined in infancy and subsequently obtained behavioral hearing levels in children with normal hearing or varying degrees of sensorineural hearing loss. Overall, the results from 211 subjects showed that the two test techniques were highly correlated, with Pearson r values exceeding .95 at each of the audiometric test frequencies between 500 and 4000 Hz. Analysis of the findings for babies with significant hearing loss (moderate to profound levels) showed similar threshold relationships to those obtained in previous studies involving adults and older children. The results for infants with normal or near-normal hearing did, however, differ from those reported for older subjects, with behavioral thresholds typically 10 to 15 dB better than would have been predicted from their ASSEP levels.

Endoscopic Group

A study to compare tympanoplasty between endoscopic and microscopic approach was conducted at NMCTH. Patients diagnosed as chronic otitis media – mucosal type with age of 13 years and above were included in the study. Audiometric test was done before and 6 weeks after surgery. Seventy cases were included for the study with random allocation of cases each in endoscope group and microscopic group respectively. Graft uptake results were assessed after 6 weeks and postoperative hearing were evaluated and compared within and between the two groups. In endoscopic group and microscopic group, the graft uptake rate was 91.4% and 88.5% respectively with no significant difference (p = 0.71) in the graft uptake rate between the groups. The mean pre and post-operative air bone gap in endoscopic group and microscopic group were 34.59 dB±8.02, 21.97±8.60 dB and32.42±10.08 dB, 18.55±8.49 dB respectively. This showed a highly significant difference in both groups(p < 0.001), showing improvement in the hearing after surgery in both the groups. The mean air bone gain were 12.62 dB and 13.87 dB in endoscopic and microscopic group respectively, with no significant difference between the groups (p = 0.553). The graft uptake rate and hearing results with endoscopic technique is comparable to that of microscopic technique. However, the endoscopic technique requires shorter operative time than the microscopic technique. Therefore, we recommend the use of endoscope for tympanoplasty in hospital as well as in camps.
