AbstractObjective:We report an atypical case of ossicular necrosis affecting the incus, in the absence of any history of chronic serous otitis media. We also discuss the current theories of incus necrosis.Case report:A male patient presented with a history of right unilateral hearing loss and tinnitus. Audiometry confirmed right conductive deafness; tympanometry was normal bilaterally. He underwent a right exploratory tympanotomy, which revealed atypical erosion of the proximal long process of the incus. Middle-ear examination was otherwise normal, with a mobile stapes footplate. The redundant long process of the incus was excised and a partial ossicular replacement prosthesis was inserted, resulting in improved hearing.Conclusion:Ossicular pathologies most commonly affect the incus. The commonest defect is an absent lenticular and distal long process of the incus, which is most commonly associated with chronic otitis media. This is the first reported case of ossicular necrosis, particularly of the proximal long process of the incus, in the absence of chronic middle-ear pathology.

Recurrent Otitis Media

To investigate the possible association of chronic otitis media and school learning problems, past and current middle ear status in 53 learning-disabled (LD) children was compared to that of 56 control children without learning problems. A history of recurrent otitis media was obtained in 23% of the LD children and in 9% of the control children. Thirty-eight percent of LD children and 16% of control children had hearing abnormalities on pure tone audiometry; 49% of LD children and 21% of control children had abnormal tympanometry. LD children had significantly more middle ear malfunction than control children. Chronic, undetected middle ear problems may play a role in the etiology of some school learning disabilities.

Background: Situation of incus erosion is common while performing tympanoplasties for cases of chronic otitis media. As none of the available techniques is said to be gold standard, a cost effective and easily available partial ossicular replacement prosthesis is employed and the postoperative hearing outcome is presented. Objectives: To assess the hearing results of ossiculoplasty using partial ossicular replacement prosthesis (PORP) during tympanoplasty. Methodology: A descriptive cross-sectional study was carried out in a tertiary referral hospital of Nepal from June 2018 to September 2019. Thirty consecutive patients who underwent tympanoplasty for chronic otitis media (inactive/mucosal) with incudostapedial discontinuity were operated using polytetrafluroethylene partial ossicular replacement prosthesis without removing the incus. Pure tone averages, air-bone gap (ABG) and air conduction gain were calculated pre and post-operatively. Results: There was no extrusion of prosthesis. The post-operative air-bone gap less than 20 dB was achieved in 23 (77%) cases. All the patients had post-operative air-bone gap of ≤25 dB. There were no major complications. Conclusion: Polytetrafluroethylene partial ossicular replacement prosthesis is safe, reliable and efficient alternative for ossiculoplasty when the incus is found to have eroded during tympanoplasty surgery.

Complement activation, as shown by increased amounts of complexes composed of Clr-Cls-Cl IA, and abnormal complexes of Clr-Cls were demonstrated in serum from patients with acute pneumococcal and chronic otitis media, serous or mucoid respectively. C1q binding substances were shown in middle ear effusions and in sera from patients with chronic serous otitis media. Presence of immune complexes and/or bacterial products capable of binding Clq results in formation of Clr-Cls-C1 IA complexes and may also cause the generation of Clr-Cls complexes. Such a dissociation of the C1 component will compromise the important opsonic function of the classical pathway.

Inverted papilloma is a very rare finding in the middle ear. It is a benign, though locally aggressive tumour with a tendency towards malignant transformation. The dia­gnosis is usually established postoperatively, based on the histological examination, because the local finding is not specific and resembles chronically inflamed tissue in chronic otitis media. Surgery is the treatment of choice. Radiotherapy is reserved for inoperable tumours or a recurrent disease. In this case report, we present a case of a 62-year-old man, who underwent canal wall down tympanoplasty for chronic otitis media in a district hospital many years ago. A few years ago he was examined for pulsatile tinnitus and hearing impairment at our clinic. A combined-approach tympanoplasty did not reveal the expected tumour (only stiff scars) and a clearance of the middle ear cavity was performed. Histological examination revealed an inverted papilloma. A CT scan performed postoperatively proved a tumour persistence. Therefore, a radical mastoidectomy was indicated. The patient is disease-free with no signs of recurrence during 32-month follow-up. Keywords: inverted papilloma – Middle ear – radical mastoidectomy

Though squamous cell carcinoma is the commonest tumor, it rarely presents in the middle ear andfollows a history of chronic ear discharge. Postauricular mastoid fistula is also a rare complicationof chronic otitis media. These two pathological changes occurring simultaneously are even rarer.We report a rare case of a 37 years old male with a history of left-sided chronic ear discharge andconductive hearing loss. Squamous cell carcinoma along with postauricular mastoid fistula wasdiagnosed based on high-resolution computed tomography scan and histopathology. Left modifiedradical mastoidectomy with tympanic membrane grafting was done under general anesthesia.Often middle ear tumor is associated with long-standing ear discharge and this case is a very goodexample. The co-occurrence of the middle ear tumor with mastoid fistula is extremely rare as boththe entities are rare in itself.

<p class="abstract"><strong>Background:</strong> Ossicular discontinuity can occur as a result of erosion by chronic otitis media or due to trauma. Reconstruction of the ossicular chain aims to surgically optimize the middle ear transformer mechanism. The goal of this study was to devise a protocol to manage the ossicular discontinuity, provide good hearing to the patients and to demonstrate that use of ossicle for ossicular reconstruction is a safe, physiological, practical, successful and cost effective method.</p><p class="abstract"><strong>Methods:</strong> The present study is retrospective study of 50 patients who underwent ossiculoplasty in our institute over the period of 2 years. Most patients presented to us with a history of chronic intermittent ear discharge and decreased hearing. Detailed clinical examination included general examination and local examination of ear, nose and throat. Examination of ear included otoscopy, tuning fork tests, and examination under microscope.  </p><p class="abstract"><strong>Results:</strong> The average pre-operative air-bone gap in patients with ossicular disruption was 34.95 dB and after ossiculoplasty was 12.93 dB. The mean air-bone closure after surgery was 27.88 dB. In most cases the post-operative air bone closure was within the range of 20 dB. The hearing results in ossiculoplasty are dependent on various factors but middle ear status in one of the most important factor in deciding the final outcome.</p><p class="abstract"><strong>Conclusions:</strong> The ossiculoplasty using autograft has stood the test of time and the results are superior to that of prosthesis. They have less rate of complications, are economic and easily available. The expertise to sculpt the ossicle can be easily developed with practice.</p><p> </p>

Group 2

The effect of recurrent middle ear disease during the first 2 years of life on auditory perceptual skills and reading ability was examined in two groups of 6- and 7-year-old children who were pair-matched by age, gender, socioeconomic status, and receptive vocabulary. Group 1 consisted of children with documented chronic otitis media at an early age, and group 2 had no history of middle ear problems. Tests of auditory perceptual skills and reading ability were administered. Significant differences in performance on all tests of auditory processing ability and reading ability were noted.
