Early complications and symptoms of cerebellopontine angle tumor surgery: a prospective analysis.

Unlabelled: Our objective is to prospectively report very early complications and outcomes of cerebellopontine angle (CPA) surgery. Between January and August 2007, 72 patients were operated on by different transpetrosal approaches in a tertiary referral center. During preoperative assessment, facial nerve function (House-Brackmann grading system), the presence of vertigo or tinnitus and caloric test results were recorded and correlated with complications and symptoms occurring daily from day (D) 1 to D 8.

Temporal breach management in chronic otitis media.

In a retrospective study performed at the Otolaryngology, Head and Neck Surgery Department, Pitié-Salpêtrière Hospital, Paris from 1991 to March 2007, we determined surgical procedures for the treatment of tegmen breaches in chronic otitis media. Forty-two cases were examined: 76% corresponded to chronic otitis media with cholesteatoma, and 24% to chronic otitis media without cholesteatoma. Twenty-eight cases were operated using a combined approach, eight cases using a single suprapetrous approach, and six cases using a transmastoid approach.

Related timing for peripheral and central plasticity in hypoglossal-facial nerve anastomosis.

The aim of this work was to determine the role of peripheral facial muscle reinnervation in the central reorganization of the blink reflex (BR) after hypoglossal-facial anastomosis (HFA). An electrophysiological study was performed on seven patients who underwent HFA after facial nerve transection during surgery for acoustic neuroma. HFA was performed within 15 days after surgery in five patients (group 1) and later for the two others (group 2).

[Anatomy and physiology of the vestibular system: review of the literature].

The vestibular system is a complex system involving not only posterior labyrinth but also central structures such as cerebellum, striatum, thalamus, frontal and prefrontal cortex to assure balance, movements and walking. Information reaching the vestibular complex are not purely vestibular but also from visual, somatosensory and cerebellar origins. The equilibrium is also a complex physiological function needing concordance of vestibular, visual and somatosensory information or either central compensation after an injury but also an integrity of the central nervous system.
