Evaluation of hearing loss by pure tone audiometry in chronic suppurative otitis media patients

Background: Hearing loss associated with the CSOM affects the patients’ communication with others and results in poor quality of life. Degree and type of hearing loss can be assessed by pure tone audiometry, which helps in predicting the status of tympanic membrane, ossicular chain, and inner ear and also helps in preoperative planning.Methods: Patients with CSOM aged 10 years and above were included in the study. All patients underwent pure tone audiometry. With the help of air and bone conduction threshold, the degree and type of hearing loss in each ear was determined. The data collected was evaluated and results are reported as rates and proportions (%). Results: Most of the ears (83%) had mild to moderate hearing loss. Average ABG observed was 31 dB. Maximum ABG observed was 55dB on right side and 50 dB on the left side. There was mixed hearing loss in 10.9% cases.Conclusions: This study reinforces the idea of using preoperative pure tone audiometry, which not only helps in planning surgery but also helps in documenting the preoperative status of patients’ sensorineural hearing loss, if present.

Chronic suppurative otitis media is one of the common otological conditions in India for which patients seek advice from an otorhinolaryngologist. Chronic suppurative otitis media is recurrent and progressive disease which is characterized with tympanic membrane perforation and suppurative discharge. Pure tone audiometry is the most common test used to evaluate auditory sensitivity. Since hearing loss is a common complication of chronic suppurative otitis media, we designed this study to evaluate preoperative pure tone audiometry findings in patients with chronic suppurative otitis media and its correlation with the intra-operative findings. Aims and Objectives: 1] To assess the intra-operative findings in patients with chronic suppurative otitis media. 2] To evaluate the correlation between the preoperative pure tone audiometry findings and intra-operative findings in patients with chronic suppurative otitis media. 3] To assess the type of hearing loss and degree of hearing loss in patients with chronic suppurative otitis media. Materials and Methods: This is an Observational study carried over a period of 3 years from August 2011 to August 2013. Total number of patients included in this study was 100. Result: Out of 100 patients studied 69 % of patients had Tubo-Tympanic type of CSOM, 31 % of patients had Attico-antral type of CSOM. In patients of Safe CSOM; Central perforation was seen in maximum cases 46.4 %, anterior central perforations was seen in 8.7 % cases, posterior central perforations seen in 20.2 % cases, and subtotal perforations seen in 24.63 % cases. In patients of Unsafe CSOM posterosuperior cholesteatoma was seen in maximum cases 67.74 %, and attic cholesteatoma was seen in 32.2 % cases. In safe CSOM patients all ossicles were intact and mobile whereas in unsafe CSOM patients only 4 patients had intact ossicular chain, while maximum patients had ossicular defect. Conclusion: Hearing loss depends on size of perforation. Hearing loss increases as the size of perforation increases. Average air conduction threshold and air bone gap did not differ significantly between various groups of ossicular defect. This shows us that neither air conduction nor air bone gap are reliable parameters on basis of which we can predict ossicular status preoperatively.

Background: The aim of tympanoplasty done for tubotympanic type of chronic suppurative otitis media (CSOM) should not only be to achieve a dry ear, but also to give hearing improvement to the patient. Aim of this study was to determine the correlation between size and site of tympanic membrane perforation with degree of hearing loss and correlation between ossicular chain status and degree of hearing loss on pure tone audiometry.Methods: Patients with tubotympanic CSOM with hearing loss upto 60 dBHL undergoing tympanoplasty were examined to know the site and size of tympanic membrane(TM) perforation. Intraoperative findings pertaining to middle ear and ossicles were noted. Results: Out of 52 patients of tubotympanic type of CSOM, hearing loss was least (31.18±7.46 dBHL) in small perforations of the TM and highest in subtotal perforations (48.74±7.83 dBHL) which was statistically significant. Hearing loss was significantly more in posterior perforation (46.61±7.02 dBHL) than in anterior perforation of TM (32.65±8.77 dBHL). There was a statistically significant difference in pure tone average hearing loss between intact ossicle group (32.87±9.77 dBHL) and eroded ossicle group (43.39±9.60dBHL). Difference in air bone gap was also significant between intact ossicle group (24.09±9.56 dB) and eroded ossicle group (31.02±9.83 dB). Multiple ossicles were eroded in nineteen patients with incus being the most commonly eroded ossicle.Conclusions: In this study, hearing loss increased with increased size of TM perforation and also with posterior perforation. Incus was found to be the most commonly eroded ossicle. Multiple ossicles were seen eroded most commonly when hearing loss was moderate. The surgeon will be better equipped to do ossiculoplasty in view of these preoperative findings and also to counsel the patient better about their expectation of hearing improvement following surgery.

Results: In age group of 20 to 60, maximum number of patients were in group of 31-40 (16), followed by 51-60 (15), followed by 20-30 (24.) Maximum positive seen in Romberg (07), followed by nystagmus (06), followed by Dix-Hallpike (06). The patients in our study (30 out of 50) were suffering from hypertension. Two patients were of Meniere’s disease and rest 16 were of SNHL, 08 were of SNHL and BPPV combined. The rest of the cases were of mixed hearing loss and other central hearing loss causes will have be ruled out.Conclusions: The main aim of study is to study clinicopathological aspects in patients with vertigo. We also studied incidence of SNHL in our study. It has been established by this study that hypertension is one the major causes of vertigo in patients whereas VEMP has not proven to be very beneficial in our study to see peripheral vertigo patients. Most of the patients with BPPV also had a normal cVEMP which showed that it was not a very reliable instrument in BPPV.

Background: Tympanic membrane perforations result mainly from infectious and traumatic etiologies. Postoperative outcomes of reconstructive surgeries of hearing mechanism have routinely been assessed by take up rates and air bone gap closure on pure tone testing. The present study was conducted to assess hearing improvement after fat graft myringoplasty.Methods: The present prospective study was conducted from 1st January 2017 to 30th June 2018. The study population consists of patients of age 18 to 60 years. The subjects with safe or tubotympanic type of chronic suppurative otitis media with small dry central perforation or perforation of the pars tensa less than 3 mm were included in the study. Pure tone audiometry (PTA) was consigned to an audiologist who was blind to the study. Air conduction threshold level was measured at frequencies 0.25 to 8 kHz and bone conduction threshold level was measured at frequencies 0.5 to 4 kHz; average air bone gap of each patient was calculated preoperatively and postoperatively at one and three months at the frequencies 500 Hz, 1000 Hz and 2000 Hz. Results: Among 30 patients, 15 (50.00%) had pre-operative bone conduction threshold in the range of 0-10 dB HL and rest 15 (50.00%) had between 11-20 dB HL. Majority of them i.e. 20 had post-operative air bone gap in the range of 0-10 dB HL whereas 02 had pre op air bone gap in this range, followed by 07 with air bone gap in the range of 11-20 dB HL as compared to 18 in the pre op and 03 in the range of 21-30 dB HL as compared to 10 in the pre op. Paired t test reveals results are significant.Conclusions: Postoperative audiometry at the end of 1 month revealed majority i.e. 14 had air bone gap in range of 0-10 dB HL thus showing improvement in hearing. Postoperative audiometry at the end of 3 months revealed maximum number of patients i.e. 20 in the range of 0-10 dB HL which showed further improvement in hearing in the form of decrease in air bone gap.

Clinical experience with transcutaneous bone conduction implants has demonstrated that they are most beneficial for patients with purely conductive hearing loss in at least one ear. Percutaneous bone conduction implants, however, have been reported to provide adequate benefit for patients with mixed hearing loss with bone conduction pure-tone averages up to 45 db hl (Tjellstrom, 1989). The results of 24 Xomed Audiant osseointegrated bone conduction hearing devices (including a clinical trial on two patients using a new, larger magnet [Neodynium Iron Boron]), plus the results of eleven patients implanted and fitted with the percutaneous bone-anchored hearing aid are reported. Aided results with these devices will be presented. In addition, general comparisons of benefit obtained with the two devices will be made for patients who exhibit similar hearing losses. Finally, a direct comparison will be made on two patients who have undergone both implant procedures.

Background: Chronic suppurative otitis media (CSOM) has been an important cause of hearing loss and ear discharge in people affected by it for a significant time now. Its prevalence is more in developing countries where the socioeconomic status is low. Poor and overcrowded living conditions, poor hygiene and nutrition have been suggested as a basis for the widespread prevalence of CSOM in developing countries. Pure tone audiometry is the easiest and the most basic procedure which needs to be performed on any patient who has history of hearing loss irrespective of the nature of the disease and the cause surrounding it. Every initial evaluation for CSOM should include audiometric testing via air and bone along with pure tone thresholds. Aim of the study was to co-relate the hearing loss to the duration of the disease in the ear in patients with CSOM and to also associate the same to the corresponding hearing changes after myringoplasty.Methods: Sixty patients were taken to be part of the study after following a strict inclusion and exclusion criteria. With proper consent, they underwent pure tone audiogram and myringoplasty. Their air bone (AC) gap and air conduction (AC) threshold results were tabulated with the duration of the disease and a consensus was reached at.Results: It was observed that the hearing loss was much lesser if the duration of the disease was lesser than one year. As the diagnosis was delayed, both the AB gap and mean AC threshold went up. The early closure of the perforation can significantly bridge the AB gap but the same cannot be said about the AC threshold as it seemed to be lesser affected by the duration.Conclusions: It can thus be concluded that AC threshold is quietly independent of the changes in the diseased middle ear as compared to the AB gap. This makes it a stronger tool in the assessment of hearing. The early diagnosis and management of tubotympanic type of CSOM can not only help in preventing complications but also aid in better hearing protection which in-turn helps in better social survival.

Objective: To assess the hearing loss among the subjects using excessive mobile phone. Methodology: 50 subjects were entered for this study with age ranging from 20 to 40 years using mobile phone for more than 5 years. 25 subjects who used mobile phone for less than (<) 60 min /day formed one group, while 25 subjects who used cell phone for more than (>) 60 min /day formed the second group. The hearing levels of all the subjects were tested using Pure Tone Audiometry (PTA). Duration of mobile phone usage was assessed by questionnaires. Results: There was a significant increase (p-value .00006) in the hearing thresholds at all frequencies in air conduction and bone conduction in right ear in test group compared with the control group. Similar result was found in the left ear except for bone conduction at frequency 4 and 6 (kilo hertz) kHz. Excessive use of mobile phone caused Sensory neural hearing loss and the prevalence was 84% in group who used mobile phone for > 60 min / day and 20% in group who used for < 60 min / day. Conclusion: Excessive use of mobile phone may cause increase in pure tone threshold associated with the duration of usage. The use for more than 5 years with more than 60 minutes daily can produce harmful effects on human hearing.
