Pediatric Cholesteatoma: An Overview of Presentation, Surgical Strategy and Outcomes of an Individualized Approach

Pediatric cholesteatomas (PC) have multifactorial aetiology, spread aggressively and there are high chances of residual/ recurrent disease after treatment. The surgical technique to manage this entity has been debatable. This study was done to (i) enumerate the presentation of PC and the surgical techniques adopted (ii) analyse the outcomes viz., residual/ recurrence rates and hearing results. A cross sectional record based study was done on 618 cases of PC operated between 1983 and 2015, at a centre dedicated to otology and lateral skull base surgery. The data which was maintained on the basis of clinical and peri- operative findings was analysed. Otorrhea (59.2%) and hearing loss (54.2%) were the common symptoms. The surgeries done were: canal wall up (CWU) (44.3%), canal wall down (CWD) (41.1%), modified bondy’s mastoidectomy (5.7%), radical mastoidectomy (4.9%), trans canal excision (1.8%) and subtotal petrosectomy (2.3%). The residual and recurrence rates were 12.6% and 7.9% respectively. A significant difference between the pre and post operative hearing was observed. The mean improvement in air bone gap was 7.7db. Residual/ recurrent disease were higher in CWU as compared to CWD group. The surgery should be individualised so that the patient remains disease free.
