Factors affecting fat myringoplasty in elderly patients with chronic otitis media: A case control study.

BACKGROUND: We compared and analyzed the surgical results of fat myringoplasty between elderly and young adult patients with chronic otitis media. We also investigated whether underlying diseases and other factors impact the surgical outcome. METHODS: We retrospectively reviewed the data of 141 patients who underwent fat myringoplasty for chronic otitis media for five years. They were compared by age, sex, underlying disease, perforation size, pre- and postoperative pure tone audiometry, postoperative otorrhea, postoperative re-perforation, and cause of re-perforation. RESULT: Postoperative re-perforation was more common in the elderly group, albeit with no significant difference (p = 0.072). The factors affecting re-perforation were insufficient fat graft (44.4%), postoperative infection (33.3%), and nasal blowing (22.2%). Our findings revealed no significant association between preoperative perforation size and re-perforation (p = 0.391). Additionally, we found no significant relationship between hypertension and re-perforation (p > 0.99), nor between age group and postoperative infection (p = 0.488). Diabetes was also not significant (p = 0.640). Following surgery, both groups exhibited a significant improvement in hearing. CONCLUSION: Although age and underlying conditions play significant roles in the healing process, our results suggest that external factors such as infection, nasal blowing, cough, and insufficient grafted fat tissue have a similarly significant impact on surgical outcomes in elderly patients with COM as they do in adults. In conclusion, the decision to perform surgery in elderly patients with COM should be based on a comprehensive assessment of the patient's overall health status, hearing, use of hearing aids, and the indications for surgery.

Our Experience in Endoscopic Button Tympanoplasty Providing High Success Rate in Varying Sizes of Perforation : A Case Series.

Cartilage tympanoplasty is a fast growing technique used to restore hearing in chronic suppurative otitis media. The technique has misnomers such as limited applicability in only small size perforations, interference with sound conducting mechanism and durability. Our experience in out tertiary care Institution with over 100 retrospective study cases prove that there is a scope of proving it to be well established technique. That could be used in par with other tympanoplasty techniques. Our retrospective case series of 100 operated between 2021 and 2024 were taken, having unilateral perforation convenience data collection purpose. The overall success rates of cartilage / button tympanoplasty of varying perforation sizes, having a wide range of pure tone audiometry statuses having successful results were discussed, which is indicated as a percentage format. In our retrospective case series, out of our 100 cases we had 90 successful graft uptake cases. The 10% cases were later followed up in our study. It was analysed and concluded that the technique was not the inhibiting factor but the post operative care had prevented the patients from having the desired results. Our results are in accordance with previous case studies for support. Pure tone audiometry were taken pre operatively and post operatively that support cartilage / button tympanoplasty. Cartilage tympanoplasty is a commonly misunderstood technique which if corrected has a wide scope to be used a s a common treatment modality. Data collected and inference were in concordance with previous studies conducted. Tragal cartilage due to its durability, low inflammatory reaction to tympanic membrane, lesser chances of retraction and long term assurance of withstanding environmental conditions has proven to be technique which can be used in regular basis. Cartilage / button tympanoplasty is a technique that has a shorter learning curve for surgeons. With a high demand of cases in chronic suppurative otitis media-Tubotympanic type, button tympanoplasty technique is an assest.

Endoscopic Rosette Cartilage Inlay-Onlay Myringoplasty: A 1-Year Prospective Study.

Since 1952, myringoplasty has evolved with various surgical techniques, including overlay, underlay, sandwich, pegging, rosette, and plugging. Overlay and underlay methods are most commonly used. In 1998, Eavey introduced the cartilage and perichondrium butterfly inlay myringoplasty, designed for small to medium-sized perforation closure, offering practical advantages such as reduced surgical time and improved hearing outcomes. A one-year prospective study (September 2022 to September 2023) in a tertiary care hospital in India involved 30 patients aged 9-52 years with inactive small central perforations. Pre-operative pure tone audiometry (PTA) results were required to be no higher than 35 dB conductive hearing loss. General or local anesthesia was used based on the patient's age. The surgical technique involved visualizing the perforation, graft preparation, and transcanal insertion. Among the 30 patients, the graft uptake rate was 100% at 3 months and 93.33% at 6 months. Pre-operative mean PTA was 29.76 dB, which decreased to 25.03 dB post-operatively, with a statistically significant air-bone gap closure of 4.73 dB. Cartilage rosette inlay-onlay myringoplasty offers an effective solution for small to medium-sized perforations, achieving high success rates (93.33%). This technique is associated with reduced surgical time, suitability for day care surgery, and minimal scarring, making it a valuable addition to routine clinical practice.

Role of Tympanometric Ear Canal Volumes in Determining Outcome of Myringoplasty in Chronic Suppurative Otitis Media Patients.

Middle ear aeration is a predictive indicator of myringoplasty's successful outcome and tympanometric ear canal volume is a novel investigation that can estimate the volume of middle ear cleft and mastoid air cells. Our aim of this study is to determine the role of tympanometric ear canal volume on myringoplasty outcome in Chronic Suppurative Otitis Media Patients. Prospective analysis involving 50 patients of CSOM was performed on patients undergoing myringoplasty from April 2022 to December 2023. Smokers, Patients with squamosal COM, Bilateral COM, Otitis Externa, and Revision surgery were excluded from the study. The successful outcome of surgery was defined as no tympanic membrane perforation on postoperative follow-up. Analysis was carried out using SPSS. V. 25 and P-value less than 0.05 was considered significant. A total of 50 patients were included in the study with a mean age of 24.4 ± 8.965 and male predominance. Overall graft uptake was 64%. Graft uptake had no significant statistical correlation with age, gender, type, location, or size of perforation. However, there is a significant effect of tympanometric ear canal volume of pathological ear and interaural tympanometric ear canal volume difference on graft uptake with p-values of 0.023 and 0.033 respectively. Tympanometric ear canal volume can predict middle ear aeration and the higher the interaural tympanometric canal difference more are the chances of successful graft uptake.

Endoscopic Cartilage Myringoplasty with Anterior Margin Preservation for Repairing Large Anterior Perforations.

Objective: This study compared the graft outcomes and complications of endoscopic cartilage inlay myringoplasty with preservation of anterior margins (IPAM) and the cartilage underlay technique with raising the tympanomeatal flap (CUTF) for repairing large anterior perforations. Materials and Methods: In total, 55 patients with large anterior perforations were recruited and allocated to the IPAM (n = 28) or the CUTF (n = 27) group. The graft success rate, hearing gain, operation time, and postoperative complications were compared between the groups at 12 months. Results: The mean operation times were 29.3 ± 2.7 minutes and 46.4 ± 3.9 minutes in the IPAM and CUTF groups, respectively (P < .001). The residual perforation rate was 0.0% in the IPAM group and 11.1% in the CUTF group (P = .222). All patients completed the 12-month follow-up. The overall graft success rate was 96.4% in the IPAM group and 88.9% in the CUTF group (P = .577). No significant differences were observed between the groups in terms of postoperative pure-tone averages for air conduction and bone conduction, air-bone gaps (ABGs), or ABG changes. In the CUTF group, 22.2% of the patients reported altered taste perception, 3.7% experienced bony external auditory canal (EAC) stenosis, and 3.7% developed EAC cholesteatoma. By contrast, the IPAM group did not have any cases of altered taste perception, EAC stenosis, or cholesteatoma. Conclusions: Endoscopic cartilage myringoplasty with IPAM and anterior perichondrium folding is a simple, effective, and minimally invasive technique for repairing large anterior perforations. It offers a high graft success rate and better hearing improvement compared to CUTF.

Platelet Concentrates Impact on Myringoplasty Outcomes in Chronic Otitis Media Patients: Systematic Review and Meta-analysis.

OBJECTIVE: We aimed to perform a systematic review and meta-analysis of myringoplasty outcomes following platelet concentrates application in patients with chronic otitis media (COM). DATA SOURCES: We searched MEDLINE, Embase, and Cochrane Central register of Controlled Clinical Trials (CENTRAL). We also performed a manual search in Google Scholar and reference lists. REVIEW METHODS: Eligible for inclusion were randomized controlled trials on COM patients undergoing myringoplasty with platelet concentrates (platelet-rich plasma or platelet-rich fibrin) compared to myringoplasty alone. The primary outcomes were graft uptake and air-bone gap (ABG) gain, while the secondary outcome was complication rate. We used odds ratio (OR) and standardized mean difference (SMD) to represent dichotomous and continuous outcomes, respectively. RESULTS: Thirteen trials (n = 1179) were deemed eligible. Platelet concentrates significantly improved graft uptake after 6 months (OR: 2.45, 95% confidence interval [CI]: 1.34-4.47, P = .004, I2 = 0%, high certainty), ABG gain (SMD: 0.36, 95% CI: 0.17-0.55, P = .0002, I2 = 0%, moderate certainty), and complication rate (OR: 0.38, 95% CI: 0.18-0.82, P = .01, I2 = 0%, low certainty). CONCLUSION: Our results showed that platelet concentrates may improve graft uptake and ABG gain and reduce complications in COM patients undergoing myringoplasty. Caution is warranted given to the relatively small sample size, as well as inconsistent reporting across included trials.

Endoscopic cartilage underlay myringoplasty with or without balloon Eustachian tuboplasty for chronic perforation with Eustachian tube dysfunction.

OBJECTIVE: The objective of this study was to compare the outcomes of endoscopic cartilage underlay myringoplasty(CNM) with or without balloon Eustachian tuboplasty (BET) for the treatment of chronic perforation with Eustachian tube dysfunction (ETD). MATERIALS AND METHODS: A total of 50 ears diagnosed with chronic perforation and ETD were randomly divided into receiving alone CNM and CNM + BET. During the 12 months follow-up, the Eustachian tube score (ETS), Eustachian Tube Dysfunction Questionnaire-7 (ETDQ-7), ET inflammation scale, hearing results and graft success rate of the patients were recorded and analyzed. RESULTS: The improvement in the ETDQ-7 score was 6.23 ± 2.51 in the CNM + BET group, which was significantly higher than that in the CNM group (4.22 ± 3.85, P < 0.01) at postoperative 3 months, however, no significant between-group difference was found at post-12 months.The graft success rate was 88.0 % in the CNM group and 92.0 % in the CNM + BET group at postoperative 3 months (P > 0.05). Also, no significant difference was found among two groups (84.0 % vs 88.0 %, P > 0.05).The ABG improvement was 13.16 ± 3.19 dB in the CNM + BET group and 9.74 ± 2.56 dB in the CNM group, with a statistically significant between-group difference (P < 0.01)at postoperative 3 months. However, no significant between-group difference was found at postoperative 12 months. During followup process, neither complications nor patulous symptoms were noted. No patients developted atelectasis or otitis media with effusion. However, myringitis was seen in 8 % patients in the CNM group and 12 % patients in the CNM + BET group. CONCLUSIONS: Although BET combined with endoscopic cartilage myringoplasty had better short-term improvement of hearing and ETDQ-7 scores compared with endoscopic cartilage myringoplasty for the treatment of chronic large perforation with ETD, the long-term outcomes was not satisfactory. Also, BET did not improve the 3-and 12 months graft success rate.

Platelet Rich Fibrin Graft in Myringoplasty: Pitfalls and Challenges.

Autologous Platelet-rich fibrin (PRF) is an amalgam of fibrin mesh, platelets and growth factors that favour wound healing. It can be easily used as a graft material in myringoplasty, making it a promising, easy to harvest and cost effective alternative compared to cartilage or fascia graft used in conventional myringoplasty. 50 patients of small to medium, dry central perforation underwent myringoplasty using PRF graft (Group 1). Results were compared to 50 patients with similar small to medium perforations who underwent conventional transcanal myringoplasty using temporalis fascia graft (Group 2): Outcome of surgery was measured by closure of perforation and improvement in hearing at 3 months. In group 1, overall closure rate was 70% while in group 2 it was 96%. For both small and medium perforations healing was significantly higher in group 2 compared to group 1, (100% vs 87.5%) for small perforations and (95.45% vs 66.67%) for medium perforations. Hearing gain was comparable in both groups in patients in whom healing of perforation occurred. PRF stands as a suitable graft material for closure of small perforations, but, lack of rigidity and early disintegration of the graft makes it less suitable for larger perforations compared to other conventional grafts such as temporalis fascia.

Comparative study of endoscopic underlay myringoplasty with or without tucking of the attached perichondrium graft when repairing large central dry perforations.

OBJECTIVE: To compare the graft success rates and hearing outcomes of underlay myringoplasty with or without perichondrium tucking of the attached perichondrium, graft perforation margins when repairing chronic large central dry perforations. STUDY DESIGN: Randomized controlled trial. MATERIAL AND METHODS: Chronic large central dry perforations were prospectively randomized to tucking perichondrium graft underlay (TPGU) and no-tucking perichondrium graft underlay (NTPG) groups. The graft outcomes and complications were compared between the two groups at 12 months postoperatively. RESULTS: In total, 61 patients with large central dry perforations were included. All patients completed 12-month follow-ups. Residual perforations occurred in 0.0 % of the TPGU group and in 12.9 % of the NTPG group (P = 0.129), and re-perforations occurred within 6 months in 0.0 % and 3.2 % of the two groups, respectively (P = 0.987). The graft success rates were 100.0 % (30/30) and 83.9 % (26/31) (P = 0.067). No significant between-group differences were observed in terms of preoperative (P = 0.547) or postoperative (P = 0.612) air bone gaps (ABGs) or mean ABG gains (P = 0.597). No graft-related complications were observed in either group during follow-up. No patients exhibited significant graft blunting or medialization; graft lateralization was noted in one patient of the NTPG group. CONCLUSIONS: Endoscopic cartilage with tucking of the attached perichondrium perforation margins during underlay myringoplasty may improve the graft success rate compared to that of the cartilage push-through technique when repairing large central dry perforations; however, the hearing improvements were comparable in the two groups.

Pediatric Myringoplasty using the Periosteum: An Institutional Overview.

Introduction Myringoplasty is a common otologic procedure to restore the integrity of the tympanic membrane in cases of traumatic or pathologic perforations. Many grafting materials have been used with different techniques. Objective In the present work, we evaluate the surgical and audiological outcomes of periosteal graft overlying the mastoid cortex through a retroauricular incision in a pediatric cohort. Methods A retrospective study was carried out involving all children aged ≤ 16 years who underwent periosteal graft myringoplasty for the treatment of chronic suppurative otitis media with dry central perforation in our hospital from April 2019 to April 2021. All patients were followed up for one year to assess the anatomical success and functional outcomes by comparing the preoperative and postoperative (after six months) results of pure tone audiometry (PTA). Results The sample was composed of 36 patients; 20 of them were female (55.6%) and 16 were male (44.4%) subjects, with ages ranging from 7 to 16 (mean: 12.7) years. Four patients underwent surgery in both ears (with an interval of 6 to 9 months). Out of 40 surgeries performed, 38 ears have shown anatomical success (95%). A highly significant improvement in hearing was obtained (the mean difference between the pre- and postoperative results of the PTA was of 14.6 ± 3.45 dB ( p < 0.001). Conclusion We advocate the use of periosteal graft in the pediatric population as a good alternative for other types of grafts, with comparable and even better functional and anatomical outcomes.

Myringoplasty Using Human Birth Tissue Allografts to Repair Large Tympanic Membrane Perforations.

OBJECTIVE: Examine outcomes among a series of pediatric patients who underwent myringoplasty using human birth tissue (BT) for repair of large tympanic membrane (TM) perforations. STUDY DESIGN: Case series. SETTING: Single-institution pediatric hospital. METHODS: Retrospective chart review of patients treated with BT during a 4-year study period. Subjects who underwent myringoplasty for large (size 40% or greater) TM perforations were included for this study. Patients with a stable perforation of at least 1 month's duration preoperatively who then followed up for at least 3 months postoperatively met inclusion criteria. RESULTS: Six subjects were included in this study. One subject underwent bilateral repair; thus, this series includes a total of 7 perforations. TM perforations ranged from 40% to 70% of the TM. At initial follow-up (median of 2 months), 5 of the 7 perforations had healed. One of these 5 had evidence of a 10% recurrent perforation at 5 months, which subsequently healed. Of the 2 patients not healed at initial follow-up, 1 had only a residual pinpoint perforation that subsequently healed; the other had a persistent 30% perforation that was possibly related to their postoperative recovery period, which was complicated by a respiratory viral illness. CONCLUSION: For large TM perforations, myringoplasty with BT grafts may be a viable alternative to longer, more invasive procedures like tympanoplasty. Larger, randomized, prospective studies are needed.

Risk Factors for Replacement of Tympanostomy Tubes After Surgical Removal for Pediatric Patients.

OBJECTIVES: Ear tube removal and patch myringoplasty are frequently performed. The indication and timing for surgery varies among otolaryngologists. This study identifies risk factors associated with the need for the replacement of tympanostomy tubes after tube removal and myringoplasty. STUDY DESIGN: Case series with chart review. SETTING: Single institution academic otolaryngology practice. METHODS: Patients younger than 12 years of age who underwent tympanostomy tube removal and myringoplasty at the University of Rochester Medical Center from March 2011 to September 2019. Patients with tympanostomy tube removal due to chronic otorrhea were excluded. RESULTS: One hundred sixty-one patients (230 ears) met inclusion criteria and had sufficient follow-up. Myringoplasty success after tube removal was 94.8%. Successful myringoplasty was associated with shorter tube duration (32 months) versus unsuccessful myringoplasty (40 months) (P = .02). Replacement tympanostomy tubes after myringoplasty occurred in 9.6% of ears. There was no difference in average patient age (P = .96) or duration of tubes (P = .74) in patients who required replacement of tympanostomy tubes versus patients who did not require tube replacement. Patients with a cleft abnormality were more likely to require tympanostomy tube replacement (P < .001). CONCLUSIONS: Most children do not need tubes replaced after removal. This study identified cleft abnormality as a factor that increased the need for replacement tubes. Longer tube durations of over 3 years negatively impacted myringoplasty success. Tympanostomy tube removal should be considered 2 to 3 years after placement in most patients with longer tube durations considered in children with a repaired cleft palate.

The Prognostic Value of Active Otitis Media on Tympanoplasty Success Rate-A Systematic Review.

OBJECTIVES: The aim is to investigate the influence of an active otitis media on the success rate of tympanoplasty in patients with a chronic otitis media (COM) and a tympanic membrane perforation. DATABASES REVIEWED: PubMed, Embase and the Cochrane Library. METHODS: The inclusion criteria were studies on closure rates of tympanoplasty performed in COM patients of any age with a tympanic membrane perforation caused by COM. The exclusion criteria were studies on patients undergoing concomitant mastoidectomy, ossicular chain reconstruction, tuboplasty, adenoidectomy, revision tympanoplasty, patients with perforations due to other conditions than COM, and letters to editors, commentaries, conference abstracts and case reports. The included articles were critically appraised using the QUIPS tool. Data on tympanic membrane closure rate were extracted, odds ratio (OR) and 95% confidence intervals (CI) of the closure rate with a wet versus a dry ear were calculated. RESULTS: The search was performed on 1 February 2023. Of 4671 articles, 16 studies were included and critically appraised. Of these observational studies (nine prospective, seven retrospective), with a total of 1509 patients (dry ear group n = 1003; wet ear group n = 506), two studies stated a significant difference in success rate, one in favour of a dry ear and one in favour of a wet ear at time of surgery. All other studies did not show a statistically significant difference. Overall, the risk of bias was considered moderate to high. CONCLUSIONS: We found no significant prognostic value of having an active otitis media during tympanoplasty on tympanic membrane closure rates. Because the overall risk of bias was considered moderate to high, no strong conclusions can be made. To be able to answer this question with higher levels of evidence, high-quality prospective or randomized studies are needed.

Role of Topical Estrogen in Outcomes of Myringoplasty: Does it Really Affect the Results of Graft Success and Hearing Thresholds?

The tympanic membrane forms a barrier between the external auditory canal and the middle ear. In the inactive mucosal type of chronic otitis media, there is a perforation in the tympanic membrane which is surgically managed by Myringoplasty. Estrogen as a growth factor has been shown to have a mitogenic effect on keratinocytes thus hastening the rate of epithelialization following injury. This property of estrogen is being studied in this study for its role in the outcomes of myringoplasty. This study was carried out from January 2021 to December 2022 in the Department of Otorhinolaryngology, of a tertiary teaching hospital in North India. Patients were assessed by history, examination, otoscopy, Audiometry, and oto-endoscopy. A total of 88 patients were taken out of which 44 patients underwent myringoplasty in which topical estrogen (estradiol valerate solution) was used, and the remaining 44 patients were taken as controls. Patients were then assessed post-operatively based on Audiometry results and graft uptake status. In the estrogen group successful Graft uptake was in seen 40 (90.9%) patients and failed in 4 (9.1%), while in the control group, it was successful in 37 (84.1%) patients and failed in 7 (15.9%), statistically there was no significant difference between two groups in terms of graft uptake (p value = 0.334). Post-operatively, in the estrogen group, the mean change in Air Conduction (AC) was 15.5 dB, the change in the air-bone gap (ABG) was 11.5 dB and for Bone Conduction (BC) it was 3.2 dB. However, in the control group mean post-operative changes in Air Conduction, Air-Bone Gap, and Bone Conduction were 12 dB, 10.7 dB, and 0.8 dB respectively. Statistically, there was a significant difference in postoperative changes in AC (p value = 0.011) and BC (p value = 0.009) between the two groups. There was no significant difference in post-operative changes in Air-Bone Gap (p value = 0.571). Topical Estrogen (Estradiol valerate) solution is cost-effective, with enriched growth factors that accelerate tympanic membrane perforation closure following myringoplasty and resulted in significant improvement in hearing thresholds both for Air Conduction and Bone Conduction.

Bilateral same-day myringoplasty: a feasible option?

PURPOSE: Retrospective evaluation of bilateral same-day myringoplasty outcomes. METHODS: Patients who underwent bilateral same-day myringoplasty from 2005 to 2019. RESULTS: Thirty-eight patients underwent bilateral myringoplasty. Mean age was 44.5 years and 55.3% patients were male. Tragal perichondrium-cartilage composite graft was the most frequently used graft material (82.9%). Perforation closure was achieved in 78.9%. Postoperative Pure Tone Average and Air-Bone Gap decreased significantly (p < 0.05), except for the Air-Bone Gap of the right ear (p = 0.058). The complications were cholesteatoma (1.3%), otorrhea (6.6%) and tympanic membrane retraction (1.3%). CONCLUSIONS: Bilateral same-day myringoplasty is a feasible procedure in selected patients. Good anatomic and functional outcomes, as well as a low rate of complications, are achieved with this procedure, improving patient comfort and allowing for a reduction in operation time and costs.

Endoscopic Cartilage Modified Inlay Technique With Preserving External Auditory Canal Skin for Repairing Posterior Marginal Perforation.

Objective: To evaluate the graft success rate and hearing gain of endoscopic cartilage myringoplasty with preserving external auditory canal (EAC) skin for posterior marginal perforation. Materials and Methods: We performed a prospective study in 36 patients with posterior marginal perforation who underwent endoscopic cartilage modified inlay technique with preserving EAC skin. Patients were followed up for 12 months. Results: All the 36 patients with unilateral posterior marginal perforation were included in this study. Clinical inosculation of the perichondrium graft and remnant tympanic membrane (TM) occurred at 2 to 3 weeks postoperatively. Simultaneously, neovascularization was initiated at the perichondrium graft. The perichondrium graft had been clinically incorporated to the EAC skin at 2 to 3 weeks postoperatively, which could not be distinguished. At 12 months, residual perforation was seen in inferior margin in one but reperforation was not. The graft success rate was 97.2% (35/36). The mean preoperative air bone gap (ABG) was 29.7 ± 3.8 dB, and the mean postoperative ABG at 12 months was 15.2 ± 3.1 dB; the difference between these values was significant (P < .05; paired-samples t test). The successful surgery rate (postoperative ABG ≤ 20 dB) was 91.7% (33/36). No any intratympanic or EAC cholesteatoma was noted during the follow-up period. Conclusions: Endoscopic cartilage modified inlay technique with preserving EAC skin for repairing posterior marginal perforation is simple and minimally invasive technique, which had shorter operative time, similar graft success rate compared with raising a tympanomeatal flap techniques.

Sometimes less is more: experience with endoscopic myringoplasty.

A retrospective review of the outcomes of patients who underwent endoscopic myringoplasties in our institution was conducted. The aim was to highlight our results with this procedure. The database of patient records was manually checked, and the patients who had undergone Endoscopic Myringoplasties were identified, and their demographics, admitting notes, operating notes, and discharge summaries were reviewed. Graft failure was considered if the patient had a perforation in the graft during the outpatient follow-up. The information was compiled, and basic statistics were derived. A total of 31 patients were identified who had undergone Endoscopic Myringoplasty. Patients' age ranged from 14-52 years. None of the patients developed any immediate postoperative complications. Follow-up otoscopic examination showed 28 patients with an intact graft and only one patient with graft failure. Two patients were lost to follow up. Our success rate with Endoscopic Myringoplasty is 96.6%, which is comparable to the international standard success rate of 80-95%. The results of this study encourage adopting an endoscopic approach where the expertise is available.

Tunable ciprofloxacin delivery through personalized electrospun patches for tympanic membrane perforations.

Approximately 740 million symptomatic patients are affected by otitis media every year. Being an inflammatory disease affecting the middle ear, it is one of the primary causes of tympanic membrane (TM) perforations, often resulting in impaired hearing abilities. Antibiotic therapy using broad-spectrum fluoroquinolones, such as ciprofloxacin (CIP), is frequently employed and considered the optimal route to treat otitis media. However, patients often get exposed to high dosages to compensate for the low drug concentration reaching the affected site. Therefore, this study aims to integrate tissue engineering with drug delivery strategies to create biomimetic scaffolds promoting TM regeneration while facilitating a localized release of CIP. Distinct electrospinning (ES) modalities were designed in this regard either by blending CIP into the polymer ES solution or by incorporating nanoparticles-based co-ES/electrospraying. The combination of these modalities was investigated as well. A broad range of release kinetic profiles was achieved from the fabricated scaffolds, thereby offering a wide spectrum of antibiotic concentrations that could serve patients with diverse therapeutic needs. Furthermore, the incorporation of CIP into the TM patches demonstrated a favorable influence on their resultant mechanical properties. Biological studies performed with human mesenchymal stromal cells confirmed the absence of any cytotoxic or anti-proliferative effects from the released antibiotic. Finally, antibacterial assays validated the efficacy of CIP-loaded scaffolds in suppressing bacterial infections, highlighting their promising relevance for TM applications.

Myringoplasty - A Rewiev of 438 Cases.

The medical records of 438 patients who underwent myringoplasty followed up for a minimum of one year in the period of 1980 and 2015 were revised. Examination under otomicroscope was done of the ear to be operated. This was carried out with a speculum under the operating microscope to be reliably asses the tympanic membrane, site of perforation, to rule out any other pathology and assess the status of ossicular chain. All the patients submitted primary myringoplasty surgery were operated under postauricular, endaural and transcanal approach with overlay, underlay and inlay methods. In the study the patients were divided into three groups depending upon the technique utilized to repair the tympanic membrane. When we compared overlay technique group with underlay technique group, it was observed that overlay technique was no statistically significant difference between these three groups in term of age wise distribution, gender wise distribution, duration of disease and cause of disease, due to matching at the time of selection. In this study the outcome in terms of graft uptake rate was slight better in the overlay technique (94%) as compared to the underlay technique (86.2%), though the difference was statistically insignificant, P>0.05. Patients selection may have had a role in the high success rate in the present study as patients presenting with middle ear pathology were excluded. The complications rate in the present study was quite low, no case in inlay group, three cases of graft lateralization in underlay group, and 19 cases in overlay group. In this study, better results were achieved with overlay technique may probably be due to less surgical manipulation and faster healing process.

Effects of no perforation margin trimming and EAC packing in cartilage underlay myringoplasty for chronic large perforations in children.

OBJECTIVE: Trimming of perforation margins and external auditory canal (EAC) packing are basic procedures in underlay myringoplasty for repairing chronic perforations. The objective of this study was to compare the operation time, graft outcome, hearing improvement, and complications of endoscopic cartilage underlay myringoplasty with and without trimming of perforation margins and EAC packing in children. STUDY DESIGN: Prospective, randomized study. SETTING: Tertiary referral center. MATERIAL AND METHODS: Pediatric patients older than 12 years with chronic perforations were randomly divided into two groups: myringoplasty with trimming of perforation margin and EAC packing (TPME) group or no trimming of perforation margin and EAC packing (NTPME) group. The operation time, graft success rate, hearing improvement, and complications were compared between the two groups. RESULTS: Fifty-two patients were ultimately included in the study. The mean operation time was 31.4 ± 4.2 min in the TPME group and 23.6 ± 1.7 min in the NTPME group; the difference was significant (P < 0.01). The rate of aural fullness significantly differed between the TPME and NTPME groups (P = 0.000). All participants were followed up for 12 months; the graft success rate did not significantly differ between the groups (88.5% vs. 96.2%; P = 0.603). No patients developed adhesive otitis media. Between the preoperative and postoperative measurements, the mean air-bone gap improved by 10.2 ± 2.8 dB in the TPME group and 11.6 ± 0.7 dB in the NTPME group; this was significant (P < 0.001) in both groups. CONCLUSIONS: Endoscopic cartilage underlay myringoplasty NTPME shorted the operation time and avoided aural fullness and EAC discomfort compared with the TPME technique; however, graft success and hearing improvement were comparable between the two techniques for repairing large perforations in children.
