ABSTRACT: We report a rare case of bilateral branchial fistulae, bilateral preauricular sinuses with bilateral conductive hearing loss, called “the branchio-oto-dysplasia syndrome” (BO syndrome). It is considered as a variant of branchio-oto-renal syndrome (BOR syndrome), in which renal anomalies is an added feature. The incidence of hearing loss and the renal anomalies as per literature is variable. It has to be kept in mind that, a case with branchial fistula can be associated with various other anomalies like preauricular pits, hearing loss, and rarely renal anomalies also.
