To describe the surgical anatomy and clinical outcomes of a technique for securing cochlear implant receiver/stimulators (R/S). Receiver/stimulators are generally secured by drilling a custom-fit seat and suture-retaining holes in the skull. However, rare intracranial complications and R/S migration have been reported with this standard method. Newer R/S designs feature a low profile and larger, rigid flat bottoms in which drilling a seat may be less appropriate. We report a technique for securing the R/S without drilling bone. ⋯ The t-pocket secures the R/S with anatomically consistent strong points of fixation while precluding dural complications. There were no cases of migration or intracranial complication noted. Further trials and device-specific training with this technique are necessary before it is widely adopted.

To determine the natural history and long-term quality-of-life (QOL) outcome after conservative treatment for vestibular schwannoma. ⋯ Conservative observation of small vestibular schwannomas may be regarded as a reasonable management option because most of these tumors do not grow during an initial period of observation. Conservative treatment of this subset of patients with small, nongrowing tumors does not significantly affect life functioning, as reflected in SF-36 survey data. However, hearing loss did progress in this population. Thus, patients should be counseled regarding this risk and generic QOL measures such as the SF-36 should be used with caution in future assessments. This study emphasizes the importance of combining generic and disease-specific QOL measures in future studies of protocols of vestibular schwannoma management.

Comparative Study
Otoneurologic dysfunctions in migraine patients with or without vertigo.
To evaluate the neurotologic findings in patient suffering from migraine with and without vestibular symptoms. ⋯ Our data seem to confirm that migraine itself can affect vestibular pathways even if patients do not complain of vestibular symptoms. Vestibular examination alone does not provide enough information for a diagnosis of migrainous vertigo. A careful clinical history is fundamental for assessing the profile of patients with migrainous vertigo.
