Neurologic Manifestations of Albershunberg Osteopetrosis

A 14-year-old who had 7episodes of relapsing unita­leral paralysis of facial nerve during 7 year-;. was admit­ted to the hospital. The X-Ray revealed Osteopetrosis, and the bone biopsy was proved this diagnosis. But there was not any bone fracture, or anemia. Pressure over fa­cial nerve caused by condensation of entire facial nerve canal. was detected by tomographia. Probablv intermitant facial nerve swelling due to mentioned pressure causes re­lapsing Facial nerve paralysis.  According to the different reports the optic nerve at­rophia is most frequent and the facial nerve Paralysis is less frequent complication, and relapsing form has never been reported. In some experiences the operation has been done only for patency of optic nerve's canal. In facial nerve complication, corticosteroid can be used for the pre­vention of intestinal calcium absorption, and finally redu­ces tJ-e nerve welling.  REFERENCES
