Potential risk factors associated to the treatment failure were as follows: the age older than 50, secondary BPPV, head trauma, the occurrence of osteoporosis, and localization of otoconia in the anterior semicircular canal. The analyzed factors did not have impact on the recurrence.

Sixty-one patients with an osteoma of the frontal or ethmoid sinuses have been studied. The following indications for surgical removal of these osteomas are suggested: osteomas extending beyond the boundaries of the frontal sinus, if enlarging, if localized in the region adjacent to the nasofrontal duct, if signs of chronic sinusitis are present, osteomas of the ethmoid sinuses, irrespective of their size and if patients with osteomas complain of headache and other causes of headache have been excluded. The operation of choice is the osteoplastic flap operation.

Sixty-four patients with a facial paralysis due to chronic suppurative otitis media were treated by surgical decompression during the 10-year period 1973 to 1982. Paralysis was clinically complete in 66% and incomplete in 34% of the patients. Cholesteatoma was found in 80%. Otogenic facial paralysis was more common as an isolated lesion not associated with other complications. When present, bone destruction of the facial canal was most frequently seen in its tympanic portion. The occurrence of facial paralysis did not depend on the extent of destruction of the facial canal. Facial nerve function recovered completely in 70%, partially in 24% and failure occurred in 6% of the patients.

HBO and IT steroid therapy could be successfully used as salvage therapies in patients with sudden deafness. Further study is needed to demonstrate superiority of one of the treatments.
