RESUMO
To compare results of inlay and overlay cartilage-perichondrium composite graft myringoplasty. The present study was conducted in the department of otorhinolaryngology, Pt. B. D. Sharma PGIMS, Rohtak. The study was conducted on 40 patients of either sex in age group of 15-50 years having unilateral or bilateral inactive (mucosal) chronic otitis media with dry ear over a period of at least 4 weeks without use of topical or systemic antibiotics after obtaining their informed and written consent. Mean age in group I was 25.25 ± 7.27 years and in group II was 25.95 ± 9.06 years. Maximum number of patients in both groups were in the age group 15-24 years. Out of the total patients, 60% were males and 40% were females. At 6 months post operatively, 95% cases in group I had successful graft take-up compared to 85% cases in group II. However, at long term follow up for 24 months, graft success rate was statistically significant in group I. In group I, 100% graft uptake was seen in large size perforation of 4 and 5 mm along with 2 mm as compared to group II, with 100% graft uptake for only small size perforation of 2 mm. The mean hearing threshold gain was 16.50 ± 5.52 dB in group I as compared to 13.03 ± 6.44 dB in group II. Mean postoperative improvement in air bone (AB) gap of 16.50 ± 5.52 dB was seen in group I as compared to 13.07 ± 6.44 dB seen in group II. The graft take up rate was found to be better in long term with inlay cartilage- perichondrium composite graft myringoplasty technique compared to over lay technique with both the groups showing significant hearing improvement post-operatively. This high success rate for graft uptake and ease to perform under local anaesthesia makes in-lay cartilage perichondrium composite graft myringoplasty technique relatively optimal to use for office based myringoplasty.

RESUMO
Langerhans cell histiocytosis (LCH) is a proliferation of dendritic mononuclear cells with infiltration into organs locally or diffusely. Most cases occur in children. LCH can also present as chronic otitis media and otitis externa due to involvement of the mastoid and petrous portions of the temporal bone with partial obstruction of the auditory canal. A 4 year old male child presented with complaints of bilateral ear discharge for 4 months and inability to walk and giddiness for 2 days. On otoscopic examination, in right ear, polypoidal tissue was present in the external auditory canal which bled on touch. CECT head and MRI brain was done which showed large altered intensities in the region of bilateral external and middle ears involving the temporal bone. It also showed a well defined ovoid expansile lesion involving the skull vault in left high parietal region. Biopsy was taken from the polypoidal tissue in the right EAC which on HPE showed features suspicious for LCH. On IHC, the tissue was found out to be immunoreactive for CD 68, CD 1a and S-100 with score of 4+ for all three of the IHC markers. Patient was later put on chemotherapy and steroids which resulted in disease remission.
