<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>

<p class="abstract"><strong>Background:</strong> Various techniques of underlay graft placement have been described in literature. In this study we compare two simple underlay techniques of temporalis fascia graft placement that is Buttonhole tympanoplasty and tympanoplasty with placement of graft lateral to handle of malleus in mucosal type of chronic otitis media patients undergoing tympanoplasty to find out which among the two is a better technique based on the audiological improvement post-operatively.</p><p class="abstract"><strong>Methods:</strong> This is a case series study which included 30 patients undergoing type-1 tympanoplasty. Group A with 15 patients underwent Buttonhole tympanoplasty and Group B with 15 patients underwent tympanoplasty with placement of graft lateral to handle of malleus.  </p><p class="abstract"><strong>Results:</strong> Post-operative hearing improvement was assessed after duration of three months. In Group A, 13 (87%) patients showed hearing within normal limits and 2 (13%) patients showed mild conductive hearing loss. In Group B, 9 (60%) patients showed hearing within normal limits and 6 (40%) of patients showed mild conductive hearing loss. Both the techniques were statistically significant.</p><p class="abstract"><strong>Conclusions:</strong> Both the techniques mentioned are simple and effective procedures. Buttonhole tympanoplasty was considered as superior technique among the two as the handle of malleus provides better anchoring for the temporalis fascia graft, intra-operative manoeuvring of the graft is easier without causing displacement of the graft, there is no reduction in the middle ear space and post-operative hearing improvement is excellent. When the handle of malleus is eroded surgeon can perform tympanoplasty with placement of graft lateral to handle of malleus.</p>

We describe a dominant Japanese patient with progressive conductive hearing loss who was diagnosed with <i>NOG</i>-related symphalangism spectrum disorder (<i>NOG</i>-SSD), a spectrum of congenital stapes fixation syndromes caused by <i>NOG</i> mutations. Based on the clinical features, including proximal symphalangism, conductive hearing loss, hyper­opia, and short, broad middle, and distal phalanges of the thumbs, his family was diagnosed with stapes ankylosis with broad thumbs and toes syndrome (SABTT). Genetic analysis revealed a heterozygous substitution in the <i>NOG</i> gene, c.645C&#x3e;A, p.C215* in affected family individuals. He had normal hearing on auditory brainstem response (ABR) testing at ages 9 months and 1 and 2 years. He was followed up to evaluate the hearing level because of his family history of hearing loss caused by SABTT. Follow-up pure tone average testing revealed the development of progressive conductive hearing loss. Stapes surgery was performed, and his post-operative hearing threshold improved to normal in both ears. According to hearing test results, the stapes ankylosis in our SABTT patient seemed to be incomplete at birth and progressive in early childhood. The ABR results in our patient indicated the possibility that newborn hearing screening may not detect conductive hearing loss in patients with <i>NOG</i>-SSD. Hence, children with a family history and/or known congenital joint abnormality should undergo periodic hearing tests due to possible progressive hearing loss. Because of high success rates of stapes surgeries in cases of SABTT, early surgical interventions would help minimise the negative effect of hearing loss during school age. Identification of the nature of conductive hearing loss due to progressive stapes ankylosis allows for better genetic counselling and proper intervention in <i>NOG</i>-SSD patients.

Background: Chronic suppurative otitis media (CSOM) is a chronic inflammation of the mucosa and periosteum of the middle ear and mastoid cavity that defined as a perforated tympanic membrane with persistent drainage for more than 2 months. Preoperative hearing threshold and air bone gap (ABG) assessment are expected to predict the ossicular status which can only be ascertained intraoperatively. This study aimed to determine the correlation between intra-operative ossicular status and the degree of conductive hearing loss assessed based on the hearing threshold and average ABG among CSOM patients in RSUP Dr. Mohammad Hoesin Palembang. Methods: Observational research using a cross sectional design. The data were collected using medical record on 64 subjects with a diagnosis of CSOM who underwent mastoidectomy surgery at Dr. Mohammad Hoesin Hospital Palembang for the period of March 2019 to June 2021. Results: From 64 samples conducted in the study, the average ossicular status score in CSOM patients was 1.84 ± 1.48, with the highest group scoring 0 being the malleus incus and intact stapes as many as 21 patients (31.3%). There was a strong positive correlation between hearing threshold scores and intra-operative ossicular status scores (p<0.005, R=0.5) and there was a strong positive correlation between ABG scores and intra-operative ossicular status scores (p <0.005, R=0.6). From the linear regression test, the most influential in predicting intra-operative ossicular status scores were gender, hearing threshold value, ABG value, and the presence of cholesteatoma Conclusions: There is a significant relationship between intra-operative ossicular status and the degree of conductive hearing loss in CSOM patients.

ABSTRACT Objective Cephalometric assessment of Eustachian tube (ET) parameters and audiological evaluation in Down syndrome (DS) and Chronic Otitis Media (COM) and comparison with controls. The ET length, Total Cranial Base (TCB), Posterior Upper Facial Height (PUFH), Maxillary Depth (MD), s-ba (sella-basion) to Palatal Line (PL) and s-ba to ET length were considered. Materials and methods The study comprised of 75 subjects of both sexes in the age range of 7 to 20 years. Digital lateral cephalometry was performed for DS, COM and controls (n = 25). Pure tone audiometry (PTA) and immittance audiometry (IA) was performed to assess audiological status. Results ET length, PUFH, TCB and MD was found to be significantly reduced in DS and COM. s-ba to PL and s-ba to ET was significantly reduced in DS and COM. The s-ba to PL and s-ba to ET length angle in moderate and severe CHL (Conductive Hearing Loss) was decreased significantly. The s-ba to ET length was significantly decreased in patients with B and C tympanogram. Conclusion Aberration in the dimension of the region of the ET can be considered as a predisposing factor for otitis media and conductive hearing loss in DS.

Loudness Summation

A new non-invasive adhesive bone conduction hearing device (ABCD) has been proposed as an alternative solution for reversible bilateral conductive hearing loss in recurrent or long-lasting forms of otitis media with effusion (OME) in children that cannot undergo surgical treatment. Our aim was to assess the effectiveness of ABCD in children with OME. Twelve normal-hearing Italian-speaking volunteers, in whom a conductive hearing loss was simulated, participated in the study. The free-field average hearing threshold was determined and, to evaluate binaural hearing skills, loudness summation and the squelch effect were assessed. Five conditions were tested: (1) unaided without earplugs, (2) unaided with bilateral earplugs, (3) aided right ear with bilateral earplugs, (4) aided left ear with bilateral earplugs, and (5) bilateral aid with bilateral earplugs. Post-hoc analysis showed a significant statistical difference between plugged, unplugged, and each aided condition. The main results were a better loudness summation and a substantial improvement of the squelch effect in the bilaterally aided. Our results suggest that ABCD is a valid treatment for patients with conductive hearing loss that cannot undergo bone conduction implant surgery. It is also important to consider bilateral aids in order to deal with situations in which binaural hearing is fundamental.

Experimental Group

Two groups of children were compared in order to determine the effect on language and speech development of the fluctuating conductive hearing loss which accompanies chronic otitis media. The experimental group consisted of 16 children, aged 5 to 9 years, with chronic otitis media and with hearing fluctuations documented by audiograms. The control group was matched for age, sex, and socioeconomic background. The language performances of the groups were compared by means of the Illinois Test of Psycholinguistic Abilities, the Peabody Picture Vocabulary Test, the Templin-Darley Picture Articulation Screening Test, and the Mecham Verbal Language Development Scale. The result shows that the experimental group was delayed to a statistically significant degree in all language skills requiring the receiving or processing of auditory stimuli or the production of verbal responses. No significant differences were found in tests measuring primarily visual and motor skills. This would suggest that the fluctuating hearing loss accompanying chronic otitis media was the cause of the delay in language development found in the experimental group. Physicians, parents, and educators need to be aware of the implication of this language handicap, as it might affect performance. Further studies are needed to evaluate the influence on permanent language ability by the periodic lack of sensory stimulation experienced during conductive hearing loss due to frequent episodes of otitis media.

Objectives.Tutoplast processed human cadaveric ossicular allografts are a safe alternative for ossicular reconstruction where there is insufficient material suitable for autograft ossiculoplasty. We present a series of 7 consecutive cases showing excellent air-bone gap closure following canal-wall-down mastoidectomy for cholesteatoma and reconstruction of the middle ear using Tutoplast processed malleus.Patients and Methods.Tympanoplasty with Tutoplast processed malleus was performed in seven patients to reconstruct the middle ear following canal-wall-down mastoidectomy in a tertiary ENT centre.Main Outcome Measures.Hearing improvement and recurrence-free period were assessed. Pre-and postoperative audiograms were performed.Results.The average pre operative hearing loss was 50 ± 13 dB, with an air-bone gap of 33 ± 7 dB. Post operative audiograms at 25 months demonstrated hearing thresholds of 29 ± 10 dB, with an air-bone gap of 14 ± 6 dB. No prosthesis extrusion was observed, which compares favourably to other commercially available prostheses.Conclusions.Tutoplast processed allografts restore conductive hearing loss in patients undergoing mastoidectomy and provide an excellent alternative when there is insufficient material suitable for autograft ossiculoplasty.

Fluctuating Hearing Loss

Long-term effects on auditory electrophysiology from early fluctuating hearing loss were studied in 27 children, aged 5 to 7 years, who had been evaluated originally in infancy. For controls (Group A), infant auditory brain stem responses (ABRs) were normal from birth to age 2 years. A second group (Group B) had intermittent conductive hearing loss. A third group (Group C) had more abnormal ABRs during infancy than Group B and more severe and frequent conductive hearing loss. For this follow-up study, all children had normal peripheral hearing at test. ABRs were obtained to monaural and binaural stimuli. Binaural interaction (BI) in the ABR was assessed in difference traces, derived by subtracting summed binaural from summed monaural waveforms.Controls differed from both groups with early hearing loss for wave III and wave V latencies and interpeak I–III and I–V latencies. There was a significant difference in the presence of BI. Eight of 9 A subjects and 8 of 9 B subjects, but only 4 of 9 C subjects, had demonstrable BI. Findings suggest that early fluctuating hearing loss disrupts later auditory brain stem electrophysiology.
