Neurofibromatosis type 1 Causing Conductive Hearing Loss

Background: Chronic suppurative otitis media attributes to 71.6% of hearing impairment in which most of them only have central perforations without any ossicular erosion or middle ear pathology. There are insufficient explanations to conclude which technique is better for type 1 tympanoplasty. Hence the study was conducted to compare and analyze the endoscopic technique with conventional microscopic technique for performing type 1 tympanoplasty.Methods: This prospective study was done at Basaweshwara teaching and general hospital attached to MR medical college, Kalaburagi from December 2015 to June 2017 after obtaining institutional ethical clearance. Patients were selected according to inclusion and exclusion criteria and randomly posted for surgery by either endoscopic or microscopic technique and results were analyzed. Results: There were 60 patients in the study between 11-65 years with mean age of 28.85±10.87 years in which were 28 females and 32 were males. All patients were divided into 2 groups in which 30 underwent endoscopic and 30 underwent microscopic type 1 tympanoplasty. In this 46.7% of the patients had left ear conductive hearing loss whereas 31.7% of patients had right ear conductive hearing loss and 21.7% of the patients had bilateral conductive hearing loss which included 22 small perforations, 33 medium size perforations and 5 large perforations of pars tensa.Conclusions: We conclude that endoscope can be a better alternative for microscope in type 1 tympanoplasty as it provides a wide panoramic view, less operating time and hospital stay with negligible scar post operatively.

Neurofibromas are common tumours of nervous system, but only few cases have the external auditory canal involvement. Here we are reporting one such case of neurofibroma in 32 year old male patient who presented with bilateral swelling in the external auditory canal and conductive hearing loss on the left side.

Conductive Hearing

Background: COM causes considerable morbidity with ear discharge, conductive hearing loss and complications. Type 1 tympanoplasty is a surgical procedure which intends improves the hearing and quality of the life. Comparison of the outcomes will help to determine the merits or demerits of a particular graft. Methods: The study was conducted in the department of ENT, SMVMCH, Pondicherry from April 2015 to April 2017. A detailed history taking, thorough clinical examination done for these patients. PTA was done before the procedure, post operatively at 3rd month. Hearing improvement analysed using different parameters like type of graft used, hearing gain, graft uptake; the data collected was tabulated and subjected to statistical analysis. Results: All the patients had COM, mucosal type, with conductive hearing loss of <40 dB. 23 patients underwent type 1 tympanoplasty by underlay technique using temporalis fascia, 19 patients using tragal perichondrium. There was no significant difference in total hearing gain at 3rd month and graft uptake between temporalis fascia and tragal perichondrium. Conclusions: This study compared the outcomes of temporalis fascia and tragal perichondrium graft with respect to hearing gain and graft uptake. Tragal perichondrium graft equally effective as temporalis fascia graft in terms of hearing gain and graft uptake.
