Galletti-Contrino manoeuvre seems to be significantly more effective than Semont-Toupet manoeuvre in the treatment of BPPV of posterior semicircular canal and may be preferential in patients with limited body movements.

The objective of this paper is to evaluate and compare hearing outcomes, intraoperative and postoperative complications and tinnitus characteristics, with particular regard to the effects of stapes surgery on the course of tinnitus. Two groups were evaluated: one group of patients were treated with classical stapedotomy and the second group was composed of patients who underwent reversal technique. Eighty-four patients aged between 22 and 62 years with otosclerosis were divided into two groups: group 1 (n = 49, 17 male, mean age 38, patients treated with classic stapedotomy) and group 2 (n = 35, 13 male, mean age 40, patients treated with reversal stapedotomy). Classical and reversal stapedotomy techniques were performed using CO2 laser; self-crimping titanium piston prosthesis were positioned in patients treated with reversal stapedotomy and classical stapedotomy. Preoperative and postoperative audiometric evaluation using pure tone audiometry (air-bone gap (ABG), bone-conduction thresholds and air-conduction thresholds). Tinnitus handicap inventory (THI) scale and intraoperative/postoperative complications were assessed in both groups. Wilcoxon's test and Friedman's test followed by post hoc analysis were used. There were no statistically significant differences in ABG, air conduction, bone conduction, and THI score variations after surgery between the two groups. Complications in both groups were not significant, and different. In conclusion, reversal and classic stapedotomies performed with CO2 laser can be considered efficient, safe and reliable techniques considering the hearing outcomes and complications recorded.

Case series Patients: Male, 50 • Male, 3 • Female, 55 Final Diagnosis: Malposition of the array Symptoms: Deafness Medication: — Clinical Procedure: Cochlear Implant 3D rendering Specialty: Audiology Objective: Challenging differential diagnosis Background: The purpose of this study is to demonstrate the advantages of 3D volume rendering in postoperative control of implants placement compared to high-resolution computed tomography (HRCT). Case Report: We describe 3 patients who underwent HRCT study with and without 3D volume rendering after surgery for cochlear implantation. In 2 patients, the traditional HRCT showed a suspected malposition of the array, excluded only by the rendering reconstruction. In the other patient, thanks to the 3D rendering, we were able to identify the complete migration of the array out of the cochlea and the tip of the electrode near the opening of internal auditory canal, while the traditional images showed only that the array was not rolled up inside the cochlea. Conclusions: HRCT showed complex anatomic structures of the inner ear and contents of the middle ear cavity. The volume rendering, in the postoperative control, generates interactive 3D images of the cochlear implant, facilitating a clearer representation of the topographic complex of the cochlea, giving more detailed diagnostic information than the HRCT.

Introduction: Zoonoses are infections transmitted from animal to man, either directly (through direct contact or contact with animal products) or indirectly (through an intermediate vector, such as an arthropod). The causative agents include bacteria, parasites, viruses, and fungi. The purpose of this review is to make an accurate examination of all zoonotic diseases that can be responsible of ear, nose, and throat (ENT) involvement. Methodology: A PubMed search was performed combining the terms (otorhinolaryngology OR rhinology OR laryngology OR otology OR mastoiditis OR otitis OR sinusitis OR laryngitis OR rhinitis OR pharyngitis OR epiglottitis OR dysphonia OR ear OR larynx OR nose OR pharynx) with each one of the etiological agents of zoonoses for the period between January 1997 and August 2012 without language restrictions. Results: A total of 164 articles were selected and examined. Larynx was the most commonly involved ENT organ, followed by oral cavity, pharynx, and neck. Bacteria were the most representative microorganisms involved. Nose and major salivary glands were affected most frequently by protozoa; paranasal sinus, oral cavity, ear, neck, nerves and upper airway by bacteria; and larynx by fungi. Conclusions: ENT symptoms and signs may be present in many zoonotic diseases, some of which are also present in industrialized countries. Most zoonotic diseases are not commonly encountered by ENT specialists. Appreciation of the possible occurrence of these diseases is important for a correct microbiological approach, which often requires special culture media and diagnostic techniques.
