RESUMO
BACKGROUND: To assess, analyze and compare the results of graft uptake using Tragal Cartilage-Perichondrium Composite (TCPC) graft with Temporalis Fascia (TF) graft in patients who undergoing surgery for chronic otitis media - squamous type. METHODS: Patients aged 13 years and above with diagnosis of chronic otitis media - squamous type undergoing modified radical mastoidectomy, either primary or revision surgery with grafting of tympanic membrane (TM) and patients undergoing excision of postero-superior retraction pocket (PSRP) were included in this study. Patients were divided in two groups: Group A-patients undergoing TCPC graft and Group B -patients undergoing TF graft. Graft uptake results were assessed between 8-12 weeks of surgery. RESULTS: In both Groups there were 30 patients each. In Group A successful graft uptake was seen in 27 patients (90 %) and failure of graft uptake was seen in 3 patients(10 %). In Group B successful graft uptake was seen in 28 patients (93.3 %) and failure in 2 patients (6.67 %).Out of the total 60 patients, 11 patients had PSRP. All 6 patients with PSRP in Group A had successful graft uptake and no retraction. Among the 5 patients with PSRP in Group B all patients had sucessful graft uptake, however, in 2 patients retraction of the tympanic membrane was seen similar to the preoperative findings. CONCLUSIONS: There was no statistical difference (p = 0.433) between the use of temporalis fascia or tragal cartilage perichondrium in patients undergoing surgery for chronic otitis media - squamous type.

This study was done to compare the pre and post-operative hearing results in patients undergoing canal wall down mastoidectomy with classical type III tympanoplasty using temporalis fascia alone. Patients of >or=5 years age with the diagnosis of Chronic otitis media (squamous) with conductive or mixed hearing loss, needing canal wall down mastoidectomy and with intact and mobile stapes suprastructure at surgery who underwent classical type III tympanoplasty were included in the study. The pre and post-operative PTA was performed and evaluated. The post-operative hearing was assessed in terms of average ABG and size of ABG closure. Mean pre and post-operative air bone gap in classical type III tympanoplasty were 37.8 dB and 29.8 dB respectively and these differences were statistically significant. The postoperative PTA-ABG ranged from 15-61.2 dB. Hearing results after type III tympanoplasty varied widely showing statistically significant improvement in mean post-operative PTA-ABG but there was a great variation.

This is a case report of myiasis in modified radical mastoidectomy cavity in a 48 years old male presented in the Department of ENT and Head and Neck Surgery, T.U. Teaching Hospital, Katmandu, Nepal. Around 50 maggots were removed from his mastoid cavity. Patient was managed with turpentine oil and antibiotics which was given to prevent secondary infection. Literature search revealed only one case report of Myiasis infestation in a postoperative mastoid cavity.
