Optokinetic afternystagmus and post rotatory nystagmus in patients with unilateral labyrinthine lesions.

The decay times of optokinetic afternystagmus (OKAN) and the vestibuloocular reflex (VOR) were measured in six subjects with chronic unilateral labyrinthectomy and in six age-matched controls. Both OKAN and VOR decay times showed parallel reduction following unilateral labyrinthectomy when the induced nystagmus beat toward the side of the lesion. The VOR decay time for nystagmus beating toward the contralateral side was also significantly reduced. Our findings support the view that the optokinetic system increases the vestibular decay time, that separate left and right velocity storage mechanisms do exist, but that the decoupling between the two sides is far from perfect.

Major facial trauma--the effect of legislation.

In January 1976, new seat belt legislation was enacted and speed limits in Ontario were reduced from 70 to 60 miles per hour. This has led to a significant decrease in major facial trauma reducing the medical experience of the surgeons handling these problems. Major facial trauma, however, is often complex and may require the services of neurosurgery and ophthalmology. It compels the otolaryngologist to be aware of these complications so that effective and efficient treatment may be instigated. A recent case illustrates these complications.

Tympanoplasty--25 years later.

The surgical details of tympanoplasty, the importance of the pathology, the proper selection and preparation of the patient have been emphasized. The results of the procedure have been discussed. While at times disappointing, the operation tympanoplasty as viewed over 25 years has been established in the armamentarium of the otologic surgeon.
