AbstractObjectiveMultiple tympanoplasty techniques have been developed with numerous differences in grafting and approach. This study aimed to improve type 1 tympanoplasty outcomes by using the ‘en hamac’ technique as well as performing a complete canalplasty for anterior perforations.MethodA retrospective review was performed using the prospective Otology-Neurotology Database tool for otological surgery. All primary type 1 tympanoplasty cases performed for tympanic membrane perforations from 2010 to 2016 were selected for analysis, all performed by one author. Minimal clinical and audiometric follow up was 18 months.ResultsTympanic membrane perforation closure was achieved in 62 of the patients (96.88 per cent). None of the en hamac cases had residual or recurrent perforation (p = 0.02). The mean remaining air–bone gap was 8.50 dB. The remaining air–bone gap was less than 10 dB in 72.55 per cent, 10–20 dB in 25.49 per cent and more than 20 dB in 1.96 per cent.ConclusionUsing the en hamac technique for anterior perforations as well as systematically performing a complete canalplasty provides multiple surgical advantages with excellent post-operative results.

<p class="abstract"><strong>Background:</strong> Tympanoplasty is a surgical procedure for closing the tympanic membrane perforation and reconstructing the tympanic membrane and hearing, commonly after trauma and chronic otitis media. The aim of the study was to compare the clinical and audiological outcomes of tympanoplasty with or without anterior tucking.</p><p class="abstract"><strong>Methods:</strong> In this prospective study, 50 patients with chronic otitis media (COM) were divided into two groups. Group 1 underwent type 1 tympanoplasty with anterior tucking method, and group 2 underwent type 1 tympanoplasty without anterior tucking. The result was measured on graft uptake and hearing outcome at 6 months postoperatively by performing pure tone audiometry.  </p><p class="abstract"><strong>Results:</strong> The hearing improvement was almost the same in both the groups. Graft uptake was good in type 1 tympanoplasty with tucking (96%) when compared to without tucking tympanoplasty (92%). Complications like residual perforation were seen in both groups equally. Anterior marginal blunting was noted (8%) in type 1 tympanoplasty with tucking.</p><p class="abstract"><strong>Conclusions:</strong> The hearing improvement of type-1 tympanoplasty with anterior tucking and without anterior tucking is the same. Type-1 tympanoplasty with anterior tucking has a better graft acceptance. The only disadvantage of type-1 tympanoplasty with anterior tucking is anterior marginal blunting.</p>

Background: Type 1 tympanoplasty or myringoplasty is the most frequently performed procedure in the field of otology. Type 1 tympanoplasty is a surgical procedure to repair and only involves the restoration of the perforated tympanic membrane. There are three most accepted methods often used universally, namely underlay, overlay, and interlay. The interlay method is a relatively new method developed in 1992 for closing tympanic membrane perforation. This method has a high success rate of 96%. Objective: To report the success of type 1 tympanoplasty with an interlay method to close large central tympanic membrane perforations at Margono Soekarjo District Hospital. Case Report: Reporting 3 cases of chronic tubotympanic suppurative otitis media with large central tympanic membrane perforation which were repaired by type 1 tympanoplasty using interlay method. Clinical Question: Does interlay method type 1 tympanoplasty performed on large central tympanic membrane perforation provide better result compared with other methods of type 1 tympanoplasty? Review Method: Studying the evidence-based literatures on type 1 tympanoplasty interlay methods through Cochrane, Pubmed, and Google Scholar databases. Based on the inclusion and exclusion criteria, three journals were relevant with the reported cases. Result: All three journals stated that interlay method type 1 tympanoplasty had high success rate in terms of closing the tympanic membrane perforation and diminishing air-bone gap. Conclusion: Type 1 Tympanoplasty interlay method could be used as an alternative for the closure of a large central tympanic membrane perforation.Keywords: Chronic Tubotympanic Suppurative Otitis Media, large central tympanic membrane perforation, interlay tympanoplasty ABSTRAK Latar belakang: Timpanoplasti tipe 1 atau miringoplasti merupakan prosedur di bidang otologi yang paling sering dilakukan.

AbstractObjectives:To investigate the impact of perforation size and other variables on the success of myringoplasty, and also to determine audiological gain following successful closure of tympanic membrane perforations of various sizes.Study design:Retrospective analysis of 130 case notes.Main outcome measures:(1) Successful closure of tympanic membrane following myringoplasty, in relation to recorded variables (i.e. perforation size, grade of surgeon, surgical technique, graft material, previous myringoplasty and smoking history). (2) Mean, four-frequency, air conduction audiometric gain following successful myringoplasty for various, pre-operatively categorised tympanic membrane perforation sizes.Results and Conclusion:The collective myringoplasty success rate was 80.8 per cent (105/130); for successful patients, the mean air conduction audiometric gain was −6.8 dB (t = 5.29, p < 0.0001). Neither perforation size nor any other assessed variable was a statistically significant determinant factor for successful myringoplasty. Air conduction audiometric gains following successful myringoplasty were directly correlated with pre-operative perforation size (−4.0 dB for 0–20 per cent perforations, −5.0 dB for 21–40 per cent, −9.1 dB for 41–60 per cent, −10.8 dB for 61–80 per cent and −13.3 dB for 81–100 per cent).

Abstract Introduction The effects of tympanic membrane perforations on middle ear sound transmission are not well characterized, largely because ears with perforations typically have additional pathological changes. It has been established that the larger the perforation, the greater is the hearing loss (HL). Aim This study aimed to correlate the location and size of tympanic membrane perforation and middle ear air space volume with the magnitude of HL in patients with tubotympanic or inactive mucosal type of chronic otitis media (COM). Materials and Methods A prospective clinical study of patients with tympanic membrane perforations due to COM and without any other ear disease and who attended the Otolaryngology services at our institute between July 2010 and December 2011 was conducted. A total of 300 ears were evaluated by performing otoendoscopy, followed by photo documentation and audiological investigations (pure-tone audiometry and tympanometry). Tympanic membrane perforations were categorized based on their size and location, and the mean air-bone (AB) gap between the various types of perforations was compared and statistically analyzed with significance level of p < 0.05. Results Out of 300 ears, maximum number of ears (n = 124, 41.3%) had large-sized perforations (> 30 mm2) that had a maximum mean AB gap of 26.43 dB, and minimum number of ears (n = 60, 20%) had small-sized perforations (0–9 mm2) that had minimum mean AB gap of 9.12 dB. The remaining were medium-sized perforations that had mean AB gap of 16.13 dB. Depending on the location, maximum were central perforations (n = 198, 66%) and minimum were anterosuperior (AS) perforations (n = 9, 3%). Based on the middle ear volume on tympanometry, maximum ears were of low-volume group (n = 246, 92%) that had larger mean AB gap of 19.96 dB HL when compared with the high-volume group (n = 24, 8%) with 11.80 dB HL. AB gap was maximum at lower frequencies and decreased with increase in frequencies except at 4,000 Hz, that is, 56.9 dB HL at 250 Hz, 42.6 at 500 Hz, 41.5 at 1,000 Hz, 32.4 at 2,000 Hz, and 49.5 at 4,000 Hz. Conclusion HL increases as the area of tympanic membrane perforation increases. There is an inverse relationship between HL and middle ear air space volume. Comparing the small-sized perforations at different sites with the middle ear volume being low, it was found that posterosuperior (PS) perforations had 4 to 7 dB greater HL than AS and anteroinferior (AI). However, the relationship was statistically insignificant. The phase cancellation effect of round window causing greater HL in posteroinferior (PI) perforations does not exist in small- and medium-sized perforations. HL is greater at lower frequencies and less at higher frequencies.

AbstractThe reported incidence of persistent tympanic membrane perforation after the extrusion or removal of Goodetype tympanostomy tubes varies from 3 per cent to 47.5 per cent.A prospective randomized study of 152 Goode-type T-tube removals is presented. In one group of 79 ears, the edge of the defect was just freshened, but in the other 73 ears, the edge was freshened and a small piece of 0.13 mm silastic sheeting placed over the defect. Follow-up was performed at six weeks and three, six and nine months and shows that the use of silastic sheeting increases the rate of closure of the perforation and also significantly decreases the number of persistent perforations at nine months.

Introduction Tympanic membrane perforation is a relatively common problem that predisposes patients to varying degrees of conductive hearing loss. Objective The objective of this study is to evaluate and analyze the frequency dependence hearing loss in tympanic membrane perforation based on the size and the site of perforation. Methods For the study, I selected 71 patients' (89) ears for the cross-sectional study with tympanic membrane perforations; I examined the size and the site of perforations under the microscope and classified them into small, moderate, large, and subtotal perforations, and into anterior central, posterior central, malleolor central, and big central perforations. I measured mean level of speech frequencies hearing loss, and its relation with the site and the size of the perforation analyzed. Results The mean hearing loss at different sizes of the perforation at all speech frequencies was 37.4 dB, with ABG of 26.6 dB, and its maximum loss was detected in subtotal perforation of 42.3 dB, with ABG of 33.7 dB, at 500 Hz frequency, while in relation to the sites, it was 38.2 dB, with ABG of 26.8 dB, and its maximum loss was detected in big central site perforation of 42.1 dB, with ABG of 33.6 dB, at 500 Hz frequency. Conclusions The hearing loss was proportionally related with the sizes of the perforations, and the posterior site had greater impact on the hearing than anterior site perforations. This was also applied to the frequency dependence hearing level, as was detected to be worse at lower frequencies as 500 Hz, than those of 1000–2000 Hz.

Sound Conduction

AbstractTympanic membrane perforation causes a sound conduction disturbance, and the size of this conduction disturbance is proportional to the perforation area. However, precise evaluation of perforation size is difficult, and there are few detailed reports addressing this issue. Furthermore, such evaluation becomes more difficult for irregularly shaped perforations. This study conducted a quantitative evaluation of tympanic membrane perforations, using image analysis equipment.A significant correlation was found between the degree of sound conduction disturbance and the perforation area; this correlation was greater at low frequencies following a traumatic perforation. The conductive disturbance associated with chronic otitis media was significantly greater at low frequencies. Circular perforations caused only minor conduction disturbance. Perforations in the anteroinferior quadrant were associated with greater conduction disturbance. Traumatic spindle-shaped perforations and malleolar perforations were associated with greater conduction disturbance.
