OBJECTIVE Clinical study of the keyhole acoustic neuroma retrosigmoid approach for facial nerve and hearing preservation. STUDY DESIGN This was a prospective case review from October 1993 to December 1998 in a referral hospital care unit. PATIENTS A total of 119 consecutive patients with a tumor size of <25 mm in the cerebellopontine angle corrected by(More)
CONCLUSION Patients implanted with the Digisonic® SP device showed better identification scores than those implanted with the Convex device, with skills continuing to improve over a longer time period. Technological improvements were beneficial in terms of speech perception in quiet. OBJECTIVE To compare speech perception skills for post-lingually deaf(More)
Middle ear implantation is an efficient procedure to restore moderate to severe sensorineural hearing loss (HL) in selected patients. Implantation of such devices requires ossicular chain integrity. Patients suffering from otosclerosis with mixed HL should be eligible for this treatment after stapes surgery with air-bone gap closure. To address this issue,(More)
OBJECTIVES We describe and evaluate the process of fixation of the Digisonic SP cochlear implant with two titanium screws. METHODS The characteristics of this implant allow cochlear implantation using a minimal incision, a subperiosteal pocket, and fixation with two titanium screws, without drilling a custom-fitted seat or creating suture-retaining holes(More)
BACKGROUND Acoustic neuroma account for 80% of cerebellopontine angle tumors. Paraganglioma is a rare tumor in this region. OBJECTIVE The authors report a case of cerebellopontine angle paraganglioma arising from the anterior inferior cerebellar artery. RESULTS The clinical and radiologic features were indistinguishable from those of a neuroma, and only(More)
Posture control is based on central integration of multisensory inputs, and on internal representation of body orientation in space. This multisensory feedback regulates posture control and continuously updates the internal model of body's position which in turn forwards motor commands adapted to the environmental context and constraints. The peripheral(More)
INTRODUCTION Vascular compression of the Vth cranial nerve is the leading cause of trigeminal neuralgia. Microvascular decompression has been promoted by Jannetta since 1970. We used the minimally invasive retrosigmoid approach, with the complementary help of endoscopic procedure. OBJECTIVES MRI results, surgical findings and pain relief were studied(More)
OBJECTIVE To describe a unique presentation of mastoid hyperpneumatization with atlantoaxial air fistulization. PATIENTS Case report, 30-year-old male patient. INTERVENTIONS Descriptive case report. MAIN OUTCOME MEASURES Subjective aural fullness, with objective tympanogram changes, induced by head rotation. RESULTS The patient complained of left(More)
BACKGROUND Arthroscopic debridement represents a salvage procedure for irreparable rotator cuff tears. It is important to accurately diagnose the patient for irreparable rotator cuff tears. The diagnosis and the therapeutic options must be explained to the patient. It is mandatory that the patient understands the primary goal of the arthroscopic debridement(More)
HYPOTHESIS Direct pressure applied on the inner ear cannot induce hearing loss. BACKGROUND Three possible causes have been described in the literature for inner ear permanent lesions during scuba diving: pressure imbalance between the middle ear and the external ear, appearance of microbubbles in the internal ear, and direct effect of pressure on the(More)
