Sound Conduction

In individuals with chronic otitis media, mixed hearing impairments are common but it is unclear whether the raised bone conduction thresholds are a reflection of the pathologic process affecting the inner ear or a combination of the high prevalence of sensorineural hearing impairments in the population along with the artificial elevation of bone conduction thresholds associated with a conductive defect. a total of 395 ears with chronic otitis media but without cholesteatoma were studied. In them, once the artificial elevation (Carhart effect) of the bone conduction thresholds, which occurs whenever there is an abnormality of the sound conduction mechanism, had been taken into account, there was no difference in the bone conduction thresholds compared with those in 920 control ears. In addition, in 100 instances, the contralateral ear was normal and there was no difference in the bone conduction thresholds between the diseased and the normal ears. Raised bone conduction thresholds in chronic otitis media are considerably likely to reflect both the Carhart effect and the high prevalence of sensorineural impairments, rather than disease damage to the inner ear.

Abstract Background Tympanoplasty is the well-established procedure for closure of perforations of tympanic membrane. Study Design This study was a prospective comparative study. Objective The objective of this study was to compare the hearing improvement and graft uptake rate between dry and wet tympanoplasty performed on tubotympanic type of chronic suppurative otitis media. Materials and Methods One hundred forty patients with tubotympanic type of chronic otitis media were selected and categorized into dry and wet ears. Tympanoplasty was performed using temporalis fascia by underlay technique in all cases. Postoperatively, graft uptake rate and hearing improvement were analyzed. Results The graft uptake rate was equal in both dry and wet ears, which was statistically insignificant. There was no statistically significant difference in the hearing improvement between the dry ears and wet ears (χ – 2.39, p = 0.122). Conclusion Factors such as age, sex, and status of the contralateral ear and wet ear did not have any impact on the postoperative graft uptake of tympanoplasty. There was no difference in the graft uptake between the dry and wet ears and there was no statistically significant difference between hearing improvement in both and wet ears.

<p class="abstract"><strong>Background:</strong> Chronic suppurative otitis media doesn’t seem to be an isolated event that occurs in a particular patient. It seems rather be the product of a series of events constitutional of the individual. The precise and critical evaluation of both ears plays a fundamental role in the prognostic evaluation of the patient. Otoendoscopy is an upcoming day care procedure in the field of otology. It has several advantages over routine otoscopy for e.g. better resolution, wider field of vision, camera connectivity etc. We aimed to study the status of contralateral ear in chronic otitis media patients and evaluate the usefulness of diagnostic otoendoscopy.</p><p class="abstract"><strong>Methods:</strong> A prospective study was done on CSOM patients attending ENT dept, SMCH using otoendoscopy, schuller radiography, pure tone audiometry, tympanometry and HRCT temporal bone.

Introduction Chronic otitis media is a widely prevalent condition in developing countries and is a cause of correctable hearing loss. The most frequent ossicular chain defect found during surgery for chronic otitis media has been a discontinuity of the incudostapedial joint. This study observes the effect of incudostapedial reconstruction using conchal cartilage on the hearing of the patient. Objectives To evaluate improvement in hearing by incudostapedial reconstruction using conchal cartilage interposition graft in tympanoplasty and to identify the independent factors associated with erosion of the long process of incus among patients with chronic suppurative otitis media tubotympanic type. Methods This study was conducted in the department of ear, nose and throat (ENT) amongst 22 patients with tubotympanic-type chronic suppurative otitis media who were found to have erosion of the long process during tympanoplasty. These patients underwent incudostapedial reconstruction using conchal cartilage. Their hearing was again reassessed at 12 weeks postsurgery, and the changes were observed. Results A statistically significant improvement in air conduction by 15.14 dB was found after undergoing incudostapedial reconstruction using conchal cartilage (p < 0.001). There was no statistically significant change in bone conduction (p value > 0.05). A total of 59.1% of patients in the study had an improvement in hearing ranging from 11 to 20 dB. It was also found that 50% of the patients had a postoperative hearing of 10 to 20 dB. Conclusion Conchal cartilage interposition graft effectively improved hearing when used for the reconstruction of the incudostapedial joint during tympanoplasty in patients of chronic suppurative otitis media.

Middle Ear Infection

The prevalence rate of chronic suppurative otitis media is high and its treatment continues to be a challenge for the otorhinolaryngologists. Due to middle ear infection, there may be pain, hearing loss and spontaneous rupture of the eardrum which results in perforation. Infections can cause a hole in the eardrum as a side effect of otitis media. The patients suffering from ear perforation or having a hole in eardrum require preventing entry of water in the ear. This article describes the development of ear cap using additive manufacturing and TRIZ (a collaborative tool) to prevent the entry of water in the ear during chronic otitis media.

Background: Chronic otitis media is an inammatory process in middle ear cleft which is treated by a common otological procedure tympanoplasty to reconstruct the tympanic membrane and to restore sound-conducting mechanism. Rigid endoscope in transcanal interlay tympanoplasty has signicant advantage as it provides magnied, and wide angle view, with better success rate and postoperative hearing gain. The Aims and objectives were to assess the outcome of endoscopic interlay tympanoplasty, in terms of graft uptake, hearing improvement and rate of complications in cases of inactive mucosal chronic suppurative otitis media. Methods: This prospective study was conducted for 1 year at our institution in 50 patients having conductive hearing loss with dry, central perforation. All patients underwent transcanal endoscopic interlay tympanoplasty and were followed up for 3months to determine the graft uptake, hearing improvement and rate of complications. Results: Graft uptake rate in the present study was found to be 98% with residual perforation as a complication in 2% patients and no other complications were encountered. Post operatively air bone gap (ABG) after 12 weeks found to be < 20 dB ABG in 84% patients. Conclusion: Endoscopic interlay tympanoplasty is a effective method with high success rate both in terms of graft uptake as well as post operative hearing improvement and can be implemented in all cases of inactive mucosal COM.

Objective: Chronic otitis media is a heterogeneous disorder. Chronic suppurative otitis media with cholesteatoma and, to a lesser extent, chronic otitis media with granulation lead to the destruction of bone structures within the middle ear. Bone loss may appear in the prominence of the horizontal semicircular canals and the bony canal of the facial nerve. The inflammatory process may spread to the bony labyrinth of the sigmoidal sinuses and the cranial cavities. Materials and Methods: The analysis comprised the examination of fragments of auditory ossicles removed during surgery in 21 patients with various types of chronic inflammation of the middle ear. The purpose of this study was to evaluate the usefulness of scanning electron microscopy in evaluating the erosion of middle ear ossicles in different types of chronic otitis media. Images captured at various magnifications were used for the best possible illustration of the observed lesions in bone tissue. Results: The observed lesions and the degree of bone surface damage were dependent on the type of chronic inflammation of the middle ear. The largest destructive changes in the ossicular chain were observed in chronic otitis media with cholesteatoma; smaller changes were observed in chronic otitis media with granulation. Conclusion: In the case of damage to the ossicles inflicted by inflammation, the use of a modeled bone block made of a temporal bone taken from outside the tympanic cavity or a biomaterial prosthesis is a good choice in ossiculoplasty.
