Facial nerve palsy following middle ear surgery is a terrible complication for every otology surgeon. Generally this happens due to identifiable causes like surgical trauma or local anaesthetic use. It IS uncommon to see facial nerve palsy more than 72 hours following the surgery. In this study we report two cases of facial nerve paralysis appearing 11 and 5 days following a successful tympano-mastoid surgery and we performed a Viral screening for Herpes Virus type for to confirm the viral aetiology of the Delayed Facial Paralysis. When an ipsilateral facial nerve palsy appears more than 72 hours after an uneventful middle ear procedure, without symptoms of any infection, a viral reactivation must be suspected.
