Modest benefit from cochlear fenestration in round window atresia warrants caution; leaves open optimal management for this rare anomaly.
In a case of isolated congenital round window absence, cochlear fenestration provided only modest hearing improvement.
Clifford et al. (1990) studied this question. Cochlear fenestration resulted in only a modest hearing improvement in an adult with unilateral round window atresia.
