Introduction?Benign paroxysmal positional vertigo is a generally benign condition
that responds to repositioning maneuvers and frequently resolves spontaneously.
However, for some patients it can become a disabling condition in which surgery
must be considered. Two different surgical techniques exist, singular neurectomy
and posterior semicircular canal occlusion. Objective?The objective of this study
is to review the current status of singular nerve section and posterior
semicircular canal occlusion as treatments for intractable benign paroxysmal
positional vertigo, and to determine if there are published data available that
favors one over the other. Data Sources?MEDLINE and OLDMEDLINE databases of the
National Library of Medicine. Data Synthesis?Four studies regarding singular
neurectomy and 14 reports on semicircular canal occlusion were analyzed. Both
techniques are reported to provide similar symptomatic benefit, with low risk of
hearing loss and balance impairment. However, anatomical and clinical studies of
singular neurectomy show it to be a more challenging technique, and considering
that it is indicated in a very small number of cases, it may be difficult to
master. Conclusions?Both singular neurectomy and semicircular canal occlusion can
be safe and effective in those few patients that require surgery for intractable
positional vertigo. Although semicircular canal occlusion requires a
postauricular transmastoid approach, it is ultimately easier to learn and perform
adequately, and thus may be considered the best alternative.
