The surgical experience with 74 glomus tumors of the temporal bone is presented. The article proposes new refinements in the classification of type C and D tumors and describes in detail the technique of blind sack closure of the external auditory auditory canal, double ligation of the sigmoid sinus and the use of a special infratemporal fossa retractor.(More)

In spite of the development of a superior (middle cranial fossa) and posterior (translabyrinthine) approach to the temporal bone, tumours situated in the infralabyrinthine and apical compartments of the pyramid and surrounding base of the skull were still a challenge for neurosurgeons and otologists as well. The infratemporal fossa approach closes the(More)
OBJECTIVES Computed tomographic (CT) scanning with slices of 1 mm or more has not been sufficient to demonstrate otosclerotic foci in most cases to date. METHODS We investigated the validity of CT scans with a 0.5-mm cubical scan technique, with and without planar reconstruction, and correlated these findings with audiological data. Forty-four temporal(More)
A method is described that allows, for the first time, intraoperative vibration modes assessment of the acoustically stimulated stapes by means of scanning laser Doppler interferometry (LDI). The study was designed to answer the following questions: 1) Is LDI practical for taking measurements during surgery? 2) Are the results comparable to the findings in(More)
The postoperative results in 392 otosclerotic ears were analyzed. Stapedotomy with wire Teflon piston does not increase the risk of postoperative fistula formation in comparison to stapedectomy with tissue graft sealing. Stapedotomy with a 0.4 mm wire Teflon piston yields poorer results in the lower frequencies 3 weeks postoperatively but results as good as(More)
Large juvenile nasopharyngeal angiofibromas are a therapeutic challenge because of their relation to major vasculature and cranial nerves at the base of the skull, and their propensity for recurrence. A classification scheme based on the growth pattern of this tumor is proposed to help the surgeon choose a procedure to access this lesion. This report(More)
OBJECTIVES To assess the potential of color Doppler sonography to identify cervical mass lesions as paragangliomas. STUDY DESIGN Prospective evaluation. METHODS Fifteen patients with 18 paragangliomas (13 carotid body tumors, 3 vagal and 2 temporal) presenting as a mass in the neck were investigated using color Doppler sonography. RESULTS All(More)
The technique and results of the infratemporal fossa surgical removal of carcinomas and juvenile angiofibromas of the nasopharynx are presented. Effective palliative removal of T4 and radical removal of T1 and T2 nasopharyngeal carcinomas was achieved. A classification of juvenile nasopharyngeal angiofibroma is presented. The infratemporal fossa approach(More)
OBJECTIVES Laser Doppler interferometry (LDI) of the eardrum allows noncontact optical analysis of its vibrations in response to sound. Although LDI has been widely used in research, it has not yet been introduced into clinical practice as an adjunctive test for otological workup. The aim of this study was to evaluate LDI as a diagnostic tool in the(More)
Petrous bone fractures (PBF) in children are relatively frequent. They are mostly diagnosed after collisions and falls. The complications typically associated with PBF were different types of hearing disorders in 69.1% of the patients who had audiometry, liquorrhea in 16.5%, palsy of cranial nerves in 10.8% (facial nerve palsy in 9.4%), bacterial(More)
