Publication Comparison of Graft Uptake and Postoperative Hearing Results between Butterfly-Cartilage and Temporalis-Fascia Myringoplasty(Institute of Medicine, 2020) Sah, Amiya K; Rayamajhi, Pabina; Bhattarai, HariABSTRACT Introduction: Myringoplasty is one of the commonest surgeries done in Otology for chronic otitis media- mucosal type (COM-mucosal type). The objective of this study was to compare the graft uptake and post-operative hearing status between butterfly-cartilage and temporalis-fascia myringoplasty. Methods: Patients of age ≥15 years with COM-mucosal type with dry, small to medium sized central perforation of pars tensa with clearly visible perforation margin were randomized into two groups of butterfly-cartilage myringoplasty and temporalis-fascia myringoplasty. Graft uptake and hearing results were assessed after six weeks and results were compared within and between the groups. Results: Thirty-one patients in butterfly cartilage group and twenty-nine patients in temporalis fascia group were analysed. Graft uptake rate was 93.5% (29/31) in butterfly group and it was 86.2% (25/29) in temporalis fascia group with no statistically significant difference (p= 0.34) between the two groups. The mean pre and post-operative air bone gap in butterfly cartilage group were 20.65dB±8.35 dB; 12.86dB±7.39dB and that in the temporalis fascia group were 19.72±6.14dB, 13.16dB±6.26dB respectively. The difference of preoperative and postoperative hearing status, obtained within the two groups was statistically highly significant (p< 0.001). However, there was no statistically significant difference in hearing results between the two groups (p= 0.54). Conclusion: The graft uptake rate and hearing results of butterfly-cartilage group and temporalis-fascia group were statistically significant within the group after myringoplasty but there was no statistically significant difference in between the two methods.

This study was done to correlate the status of mastoid with outcomes of myringoplasty with cortical mastoidectomy in mucosal otitis media with high risk perforation. Methods: This prospective, observational study was done at Department of Otorhinolaryngology and Head and Neck Surgery, Tribhuvan University Teaching Hospital. Thirty-four patients of ag|e 15 and above with chronic mucosal otitis media having high-risk perforation undergoing cortical mastoidectomy with myringoplasty were included. The status of middle ear, aditus, and mastoid air cells were assessed. Post-operatively, patients were assessed for graft uptake and hearing after three months. The post-operative graft uptake and hearing results were correlated with the peroperative status. Four patients who had preoperative sensorineural hearing loss were studied in terms of graft uptake only. Results: The graft success rate in patients with normal mastoid air cells was 90% whereas in diseased cases was 71.4% which was statistically not significant with p value 0.20. The success rate in terms of hearing was 68.8% in normal mastoid whereas it was 64.3% in diseased mastoid which was statistically not significant with p-value of 1. Conclusion: In correlation with the status of mastoid air cells with graft uptake and hearing result, the observed differences were not statistically significant. However, averages of post-operative air conduction threshold and air-bone gap of all cases were better as compared to preoperative levels.

Facial canal and ossicles are in close proximity in the middle ear space and they share the same pathogenesis of the bony erosion. Ossicular chain erosion found intraoperatively due to cholesteatoma, may suggest the likelihood of facial canal dehiscence. This study was conducted to assess the relationship between ossicular chain erosion and facial canal dehiscence in chronic otitis media squamous. Methods: It is a retrospective chart review of patients who had mastoidectomy done for chronic otitis media squamous in Tribhuvan University Teaching Hospital from January 2014 to December 2018. The operative findings of facial canal dehiscence were correlated with ossicular chain status. Results: Among 158 cases, facial canal dehiscence was seen in 20 (12.7%), of which, 19/20 (95%) had ossicular erosion. Majority (90%) of dehiscence was in the horizontal segment. Incus was the most common ossicle to be eroded. Among the ossicles, stapes erosion was related to the facial canal dehiscence with odds ratio of 3.216 (1.235-8.374) and p-value 0.03. Conclusion: Among the ossicles, there is a relationship between the stapes erosion and the facial canal dehiscence in chronic otitis squamous. Erosion of ossicular chain especially stapes should alert surgeons towards the possibility of facial canal dehiscence. Keywords: Chronic otitis media squamous, facial canal, ossicular erosion
