Objective Surgical precision would be better achieved with the development of an anatomical monitoring and controlling robot system than by traditional surgery techniques alone. We evaluated the feasibility of robot-assisted mastoidectomy in terms of duration, precision, and safety. Study Design Human cadaveric study. Materials and Methods We developed a multi-degree-of-freedom robot system...

OBJECTIVES/HYPOTHESIS Antimicrobial prophylaxis is still a matter of debate in ear surgeries. Previous studies have focused on prophylaxis in middle ear surgery alone without inclusion of mastoidectomy. We therefore investigated efficacy of two regimes of antimicrobial prophylaxis in tympanoplasty with cortical mastoidectomy done for mild middle ear disease in chronic otitis media. STUDY DESI...

Background Cognitive overload can inhibit learning, and cognitive load theory-based instructional design principles can be used to optimize learning situations. This study aims to investigate the effect of implementing cognitive load theory-based design principles in virtual reality simulation training of mastoidectomy. Methods Eighteen novice medical students received 1 h of self-directed vi...

Introduction: This study was designed to evaluate the usefulness of mastoid cavity obliteration with combined bone pâté and Palva flap in the prevention of problematic mastoid cavities after canal wall down mastoidectomy.   Materials and Methods: In a prospective longitudinal study with a mean follow-up of 28 months conducted between 2008–2012, a series of 56 ears in 48 patients with chronic ot...

Introduction  Chronic otitis media can cause multiple middle ear pathogeneses. The surgeon should be aware of relation between ossicular chain erosion and other destructions because of the possibility of complications. Objective  This study aimed to investigate the rates of ossicular erosion in cases of patients with and without facial nerve canal destruction, who had undergone mastoidectomy du...

Introduction The objectives of mastoidectomy in cholesteatoma are a disease-free and dry ear, the prevention of recurrent disease, and the maintenance of hearing or the possibility to reconstruct an affected hearing mechanism. Canal wall down mastoidectomy has been traditionally used to achieve those goals with greater or lesser degrees of success. However, canal wall down is an aggressive appr...

Objective. The aim of this report is to provide a review of the current literature for assessment of performance for mastoidectomy, to identify the current assessment tools available in the literature, and to summarize the evidence for their validity. Data Sources. The MEDLINE database was accessed via PubMed. Review Methods. Inclusion criteria consisted of Englishlanguage published articles th...

Objectives. Tutoplast processed human cadaveric ossicular allografts are a safe alternative for ossicular reconstruction where there is insufficient material suitable for autograft ossiculoplasty. We present a series of 7 consecutive cases showing excellent air-bone gap closure following canal-wall-down mastoidectomy for cholesteatoma and reconstruction of the middle ear using Tutoplast process...

OBJECTIVE To evaluate the use of ear endoscopy in the postoperative management of open mastoidectomy cavities, and to test whether ear endoscopy improves inspection and cleaning compared with ear microscopy. METHODS Prospective study. Thirty-two ears were divided into two groups: group 1, examination and cleaning of mastoid cavities under endoscopic visualization after microscopic standard ea...

Objective: Describe the clinical course and management of a labyrinthine cyst associated with a labyrinthine fistula arising in a longstanding cavity after a canal wall down mastoidectomy. Study Design: Case report. Setting: University Hospital, tertiary referral center. Patients, Intervention, and Results: A 71-year-old woman who underwent left radical mastoidectomy at age 7 was referred to ou...
