EFFICACY OF PERMEATAL ENDOSCOPIC MYRINGOPLASTY IN INACTIVE (MUCOSAL) CHRONIC OTITIS MEDIA

Objective: To determine the efficacy of permeatal ednoscopic myringoplasty, in inactive (mucosal) COM regarding, graft take and hearing improvement. Study Design: Quasi-experimental study. Place and Duration of Study: ENT Department, Pak Emirates Military Hospital, Rawalpindi, from Aug 2019 to Feb 2020. Methodology: This was conducted on a sample size of n=100. Patients having inactive (mucosal) COM with dry central small, medium and large perforations were included. Patients were divided in to three groups on the basis of age, group A 15-30 years, group B 31-45 years and group C 46-60 years. All the patients underwent per-meatal endoscopic myringoplasty, without raising the tympano-meatal flap, under general anesthesia. Patients were followed up over a period of six months. Graft take was assessed by microscopy. Hearing was assessed by Pure Tone Audiometry (PTA) with improvement in air bone gap to 15db as primary end point. Data was collected on structured performa. Data was analyzed using SPSS version 17. Results: In this study, 33 (33%) were males and 67 (67%) were females. Age ranged 15-60 years. Out of 5 patients lost to follow up. A total of 95 completed their follow up. Based on age of the patients, in group A, successful graft take was 100%. In group B, it was 91% & in group C it dropped to 46%. On the basis of tympanic membrane perforation size, the graft success rate in small perforations was 94.8%; in medium sized perforations it was 86.8% and in large sized perforations of tympanic membrane it was........

Comparison of Endoscopic Cartilage Myringoplasty in Dry and Wet Ears With Chronic Suppurative Otitis Media

Objectives: This study compared the rate of graft success, as well as hearing improvement and dry ear time between dry ears and wet ears with otomycosis or without otomycosis in patients with chronic suppurative otitis media (CSOM) after endoscopic cartilage myringoplasty. Methods: This retrospective study was conducted in a tertiary hospital in Shanghai. In total, 83 patients with CSOM (43 with dry ears and 40 with wet ears) were included. Among the 40 patients with CSOM and wet ears, 25 exhibited otomycosis. All patients underwent endoscopic myringoplasty, and perforations were repaired using tragal cartilage with a single-sided perichondrium. Patients were followed up for at least 6 months. Pure-tone hearing was examined preoperatively and at 3 months postoperatively. The graft uptake rate, hearing improvement, and dry ear time were compared between the groups. Results: The graft success rate did not differ significantly between the dry-ear and wet-ear groups (95.35% and 90.00%, respectively). Furthermore, the graft success rate also did not differ significantly between patients with wet ears and otomycosis and those with wet ears without otomycosis (92.00% and 86.67%, respectively). Hearing gain did not differ significantly between the dry-ear and wet-ear groups. No significant difference in hearing gain was also found in patients with wet ears with or without otomycosis. However, the time to dry ear was significantly longer in the wet-ear group than in the dry-ear group. Conclusion: Patients with CSOM and wet ears required more time to achieve a completely healthy status. However, the graft success rate and hearing improvement were not affected by a wet middle ear and otomycosis. Thus, endoscopic myringoplasty using tragus cartilage is an effective treatment for refractory CSOM in patients with wet ears and otomycosis.

Myringoplasty With an Ultrathin Cartilage-Perichondrium Complex Graft Versus Temporalis Fascia Graft: A Propensity Score–Matched Analysis

Objective To compare endoscopic myringoplasty using the cartilage-perichondrium complex as a graft (test group) with temporalis fascia microscopic myringoplasty (control group). Study Design A retrospective cohort study. Setting Department of Otorhinolaryngology in a tertiary Chinese hospital. Methods Data were collected on patients between 2017 and 2019. To balance the baseline characteristics between groups, we performed a propensity score–matched analysis, and 44 patients were included in each group. Hearing improvement and eardrum closure rates were compared, and risk factors affecting them were analyzed. Results In the control and test groups, 90.90% and 86.36% of patients had a mean air-bone gap ≤20 dB after the surgery, respectively ( P = .843). The air conduction (AC) threshold gain at each frequency was similar in the 2 groups ( P > .05). The closure rates were 95.45% and 93.18%, respectively ( P = .645). The air-bone gap improved significantly after surgery, F(1, 61) = 6.729, P = .012. Age, group, middle ear mucosal status, and location of the perforation did not affect the change in air-bone gap or the drum closure rate ( P > .05). However, there was an interaction between the change in air-bone gap and the size of the perforation, F(1, 61) = 11.067, P = 0001. Conclusion Endoscopic myringoplasty using a cartilage-perichondrium complex graft is comparable with traditional surgery. Age, location of the perforation, and middle ear mucosal status did not significantly affect the change in air-bone gap or the drum closure rate. A perforation size ≥50% was always associated with a better air-bone gap improvement.

The outcomes of endoscopic myringoplasty: elevating a tympanomeatal flap or not

ObjectiveThe aim of this study was to compare the differences between the no tympanomeatal flap approach and the tympanomeatal flap approach in endoscopic myringoplasty.MethodA total of 132 patients with tympanic membrane perforation were randomly divided into two groups: the no tympanomeatal flap approach group (group A, 56 ears) and the tympanomeatal flap approach group (group B, 76 ears). A comparison between the two groups was made.ResultsThe average operation time of group A was 36.00 ± 5.24 minutes, which was significantly shorter than that of group B, which was 43.89 ± 4.57 minutes (p = 0.002). The blood loss of group A was 5.08 ± 1.83 ml, which was significantly less than that of group B (9.67 ± 2.29 ml; p < 0.001). There were no differences in the degree of hearing improvement, the rate of hearing improvement, the dry ear time (when the external auditory canal and the operating cavity were dry) after operation and the success rate of tympanic membrane repair when compared between the two groups.ConclusionCompared with group B, group A (no tympanomeatal flap approach) can achieve the same effect but has the advantages of a shorter operation time and less blood loss during the operation.

Transcanal endoscopic myringoplasty: a retrospective study

<p class="abstract"><strong>Background:</strong> Transcanal myringoplasty has the advantages of demanding lower operative time and minimal external incisions. It can be performed using the microscopic or endoscopic approach.</p><p class="abstract"><strong>Methods:</strong> This retrospective study was conducted in the Department of ENT and Head and Neck Surgery, SMGS Hospital, Jammu from January 2018 to January 2020. Patients attending ENT OPD with central dry perforation of tympanic membrane were selected for endoscopic transcanal myringoplasty. Written and Informed consent were taken. During surgery, various parameters were noted including duration of surgery and hospitalization. These patients were followed through a period of 6 months and assessed using pure tone audiometry and graft uptake was seen. </p><p class="abstract"><strong>Results:</strong> Out of 40 patients, male: female ratio was 1.2:1. Time taken for surgery was less than 60 minutes in 16 (40%) patients whereas in 24 (60%) patients it was between 60-120 minutes. In our study the patients with small perforation had excellent graft uptake rates (18/19 patients, 94.73%), whereas patients with medium sized perforation showed graft uptake rate of 76.47% (13/17 patients). Objective analysis of cosmetic result was done at the end of six month and revealed that none of the patient had visible scar. Mean pre-operative air bone gap was 24.38 dB whereas mean postoperative air bone gap was 8.34 dB. Mean improvement comes out to be 16.04 dB.</p><p class="abstract"><strong>Conclusions:</strong> Endoscopic myringoplasty was found to be equally effective, less morbid and very cost effective in small central perforations.</p>

A comparative study of endoscopic and microscopic myringoplasty in a rural tertiary care teaching hospital

<p class="abstract"><strong>Background:</strong> Myringoplasty is the procedure done to repair the tympanic membrane perforation. In this study we aimed to compare the results of endoscopic myringoplasty and microscopic tympanoplasty.</p><p class="abstract"><strong>Methods:</strong> A total of 50 patients with central perforation of tympanic membrane and dry ear of minimum 6 months were divided into two groups of 25 each. The even serial numbers were subjected to microscopic myringoplasty through post aural route and odd serial numbers were subjected to endoscopic myringoplasty done through endomeatal route. Both the procedures were done under general anaesthesia. Dried temporalis fascia graft was used and follow up till 1 year post op. Air-bone gap closure, average time taken for surgery, success and failure rates, scar evaluation by doctor and patient along with postoperative return to routine activity were compared. The p value was calculated to find out statistical significance. </p><p class="abstract"><strong>Results:</strong> Post operatively the average air-bone gap reduced to 12.6 dB in endoscopic group and 14.28 dB in microscopic group. There was no statistical significant difference in the time taken for both the procedures. There was significant difference in the assessment of postoperative scar and number of days taken for return to routine activity. The success and failure rates of both the procedures were also found to be comparable.</p><p><strong>Conclusions:</strong> Our study showed that the success rates and average time taken for the procedures were the same for both the techniques but a better cosmetic appeal and considerably fewer days for return to routine activity by the patients who underwent endoscopic procedure.</p>
