Destructive surgeries are irreversible and involve removing entire functionality of most, if not all, of the affected ear; as of 2013, there was almost no evidence with which to judge whether these surgeries are effective.  The inner ear itself can be surgically removed via labyrinthectomy, although hearing is always completely lost in the affected ear with this operation.  The surgeon can also cut the nerve to the balance portion of the inner ear in a vestibular neurectomy . Hearing is often mostly preserved; however, the surgery involves cutting open into the lining of the brain, and a hospital stay of a few days for monitoring would be required. 
15 mg/kg/dose IV every 12 hours. For systemic infection in which meningitis can be excluded, treatment should continue for at least 14 days or until clinical criteria for improvement are met. For systemic infection in which meningitis cannot be excluded, treatment should continue for at least 2 to 3 weeks or until clinical criteria for improvement are met. Prophylaxis to complete an antimicrobial course of up to 60 days will be required in both cases. Ciprofloxacin, in combination with appropriate antimicrobial therapy, is a preferred therapy for systemic anthrax infection. For systemic infection without CNS involvement, dual combination IV therapy with ciprofloxacin and a protein synthesis inhibitor (., clindamycin, linezolid, doxycycline) is recommended. For documented or suspected CNS infection, triple IV therapy with ciprofloxacin, a beta-lactam/glycopeptide, and a protein synthesis inhibitor (., linezolid, clindamycin) is recommended.
