AbstractObjective:To develop an autologous total ossicular replacement prosthesis with sustainable hearing results.Methods:The ears of 40 patients, who had chronic otitis media with absent suprastructure of the stapes and long process of the incus, were repaired using the autologous total ossicular replacement technique. Post-operative results were evaluated after 6 and 12 months on the basis of average pure tone air conduction and average air–bone gap measured at 0.5, 1, 2 and 3 kHz.Results:Successful rehabilitation of pure tone average to 30 dB or less was achieved in 75 per cent of patients, and air–bone gap to 20 dB or less was attained in 82.5 per cent of patients. Overall mean improvement in air–bone gap was 23.9 ± 8.5 dB (p < 0.001). Mean improvements in air–bone gap were significantly greater (p < 0.05) in the tympanoplasty only group (27.3 ± 6.6 dB) and the intact canal wall tympanoplasty group (25.9 ± 6.3 dB) than in the canal wall down tympanoplasty group (16.3 ± 8.9 dB).Conclusion:This paper describes an autologous total ossicular replacement prosthesis that is biocompatible, stable, magnetic resonance imaging compatible and, above all, results in sustainable hearing improvement.

<p class="abstract"><strong>Background:</strong> The objective of the study was to compare the over underlay tympanoplasty technique with classical underlay tympanoplasty in terms of hearing impairment, graft acceptance and complications.</p><p class="abstract"><strong>Methods:</strong> 60 patients of chronic otitis media, mucosal, inactive, aged between 16-60 years who presented to ENT OPD with small, medium, large and subtotal perforations having mild to moderate conductive hearing loss were included in the study. After taking informed consent, patients were randomly divided into 2 groups containing 30 patients each. In group A, graft was placed medial to the handle of malleus and medial to the annulus (underlay technique), while in group B, graft was placed lateral to the handle of malleus and medial to the annulus (over underlay technique). Both groups were reviewed after 6 months. Pre-operative and post-operative air bone gap were compared. Surgery was considered successful based on post-operative graft uptake, hearing improvement and maintenance of middle ear space.  </p><p class="abstract"><strong>Results:</strong> In group A, re-perforation was seen in 8 cases (26.7%) whereas only 3 cases (10%) in group B had re-perforation. Medialization was noted among 4 patients in group A (13.3%), and was absent in group B. Lateralization was absent in both the groups. Post-operative hearing threshold in group A was 6.2±4.56 dB and in group B was 11.45±7.38 dB.</p><p class="abstract"><strong>Conclusions:</strong> Over underlay tympanoplasty is a safer technique as compared to classical underlay, showing lower rates of re-perforation or medialization and a significant improvement in hearing. Hence over-underlay is an effective method, having higher success rates.</p>

We recorded auditory-evoked magnetic responses with a whole-scalp 122-channel neuromagnetometer from seven adult patients with unilateral conductive hearing loss before and after middle ear surgery. The stimuli were 50-msec 1-kHz tone bursts, delivered to the healthy, nonoperated ear at interstimulus intervals of 1, 2, and 4 seconds. The mean preoperative pure-tone average in the affected ear was 57 dB hearing level; the mean postoperative pure-tone average was 17 dB. The 100-msec auditory-evoked response originating in the auditory cortex peaked, on average, 7 msecs earlier after than before surgery over the hemisphere contralateral to the stimulated ear and 2 msecs earlier over the ipsilateral hemisphere. The contralateral response strengths increased by 5% after surgery; ipsilateral strengths increased by 11%. The variation of the response latency and amplitude in the patients who underwent surgery was similar to that of seven control subjects. The postoperative source locations did not differ noticeably from preoperative ones. These findings suggest that temporary unilateral conductive hearing loss in adult patients modifies the function of the auditory neural pathway. (Otolaryngol Head Neck Surg 1998;119:125-30.)

BACKGROUND: Although brucellosis can lead to multisystem complications, involvement of the ear in brucellosis is rarely reported in the literature. The purpose of this study was to assess the hearing status of patients with brucellosis. STUDY DESIGN: Thirty-two patients with brucellosis were included in the study. Pure tone and speech audiometry and tympanometry were performed in the patients. RESULTS: The mean pure tone averages of the patients were within normal limits and were similar in both ears ( P > 0.05). The pure tone averages of the patients with or without anti- Brucella treatment were not significantly different ( P > 0.05) and were within the normal limits. When the hearing levels of these patients were compared at the frequencies of 250, 500, 1000, 2000, 4000, and 8000 Hz, there was no significant difference as well ( P > 0.05). CONCLUSIONS: Peripheral brucellosis does not appear to be associated with hearing loss.

Background: The history of tympanoplasty is well over a century. Type 1 tympanoplasty is an established procedure worldwide with a variation in the outcome.Aims and Objectives: To analyze the outcome of Type 1 tympanoplasty surgeries in terms of graft success and hearing improvement done at the Ear Department of Biratnagar eye hospital in eastern Nepal and discuss the various factors that might have influenced it.Materials and Methods: Retrospective analysis of records of the cases that underwent Type 1 tympanoplasty from August 2013 to January 2015 was done. The factors analysed were age, gender, the side of the affected ear and the perforation size. Appropriate Statistical test was applied and the results were discussed.Results: A total of 151 cases of type 1 Tympanoplasty were analysed were females had higher frequency than males, with higher incidence at younger age. The mean age of successful cases was 28.53. Females had a better success rate in terms of graft success compared to males. Moderate size perforations had the best outcome of graft success and least were of small size perforations. Of all cases analyzed, hearing improvement was observed in maximum cases.Conclusion: There was no significant influence of age or gender on the hearing outcome. The difference of hearing improvement according to size of perforation was also not significant.Asian Journal of Medical Sciences Vol.7(2) 2015 55-60

The aim of this study was to evaluate the success of stapedectomy in patients who have previously had a tympanoplasty because of chronic otitis media (COM). Fourteen patients from a private otology practice had undergone tympanoplasty for COM and subsequently underwent stapedectomy. Measurements were taken of the air-bone gap (ABG) closure and pure tone average (PTA) which showed hearing improvement. Patients had a mean 36.9 dB PTA hearing gain with 79 per cent closing the ABG to within 20 dB. The need for stapedectomy alone is a rare occurrence for patients with a history of COM requiring a tympanoplasty. Hearing improvement following stapedectomy in these cases was significant, although somewhat less than following traditional stapedectomy in otosclerosis alone.

Introduction             Chronic otitis media (COM) is a most common and prevalent disease of the middle ear. COM has been defined as a longstanding inflammatory condition of middle ear and mastoid, associated with perforation of the tympanic membrane. Tympanoplasties are common surgeries performed for chronic otitis media in inactive mucosal type. Any otological surgery may involve a menace/ hazard of hearing loss post operatively.             In this study, an attempt was made to correlate, size of tympanic membrane perforation, pure tone audiometry and intra-operative findings in tympanoplasties, results were analysed and conclusion drawn. Materials and Methods Forty patients attending ENT OPD with chronic otitis media (COM), inactive mucosal type, with conductive hearing loss undergoing tympanoplasties who were willing to participate in the study were selected.  Ear was examined pre-operatively to assess the size of perforation and then, pure tone audiometry (PTA) was done to assess the type of hearing loss and its severity. During tympanoplasty, middle ear was inspected for ossicular status and any other pathology was noted. Later, the size of tympanic membrane perforation, pure tone audiometry and intra operative findings were correlated with each other and analysed. Result  In small and medium sized perforation, PTA and intraoperative findings correlated with each other. Whereas, in large and subtotal perforation, there was no correlation. Conclusion             In small and medium sized perforation, middle ear inspection may not be necessary. Whereas, in large and subtotal perforation it is necessary.
