: To determine the immediate and short-term efficacies of mastoid oscillation vs. Gufoni maneuver in treating the apogeotropic type of horizontal canal benign paroxysmal positional vertigo (HC-BPPV), we designed a randomized, prospective, sham-controlled study. In eight dizziness clinics in Korea, 209 consecutive patients with apogeotropic HC-BPPV were enrolled. The patients were randomly assigned to receive a single application of Gufoni (n = 70), mastoid oscillation (n = 67), or sham maneuver (n = 72)...

OBJECTIVE: This study retrospectively investigated whether polyglycolic acid (PGA) sheet attached to the bone surface using fibrin glue facilitate faster epithelialization of the mastoid bowl after canal wall-down (CWD) tympanoplasty compared to a simple dressing using poly-N-acetyl-glucosamine (Kichin) sheet. MATERIALS AND METHODS: After completion of the CWD tympanoplasty, PGA sheet (n=16, PGA group) with fibrin glue or Kichin sheet (n=38, Kichin group) were placed on the bone surface of the mastoid bowl...

Ameloblastoma is a locally aggressive tumor derived from odontogenic epithelium. Although benign, its clinical behavior can often exhibit malignant characteristics. It is marked by slow and persistent growth with infiltration of adjacent tissues. Almost 70% occur in the mandible in patients older than 30 years. Recurrence of ameloblastoma from inadequate treatment is frequent. Because of its slow growth, recurrences can present decades after primary surgery. A primary ameloblastoma in an area outside the mandibular, maxillary, and infratemporal fossa regions has not been described in detail to date, with only 1 possible case mentioned in the literature...

INTRODUCTION: A consensus is emerging amongst otologists that obliteration of the mastoid cavity that results after modified radical mastoidectomy is a sound option to prevent cavity related problems such as otorrhoea, infection, granulation tissue and hearing loss. A variety of techniques have been proposed to perform the obliteration. AIM: The present study aimed to compare the conventional method of mastoid cavity obliteration by vascularised temporalis myofascial flap with deep temporal fascial-periosteal flap in canal wall down mastoidectomy...

Conventional dental implants have been reported for nasal and orbital regions but due to limited thickness of calvarium they are not used in mastoid region. Onlay bone grafting in skull concomitant with implants is a predictable method and experimental animal studies confirm it. Parietal bone and lateral mandibular ramus are suggested source of bone grafts and dental implants with 7 mm length can be used safely. Increased fixture length may lead to increase survival in long term.

PURPOSE: The aim of the study was to validate a minimally invasive, multi-port approach to the internal auditory canal at the lateral skull base on a cadaver specimen. METHODS: Fiducials and a custom baseplate were fixed on a cadaver skull, and a computed tomography image was acquired. Three trajectories from the mastoid surface to the internal auditory canal were computed with a custom planning tool. A self-developed positioning system with a drill guide was attached to the baseplate...

HYPOTHESIS: Descriptive statistics with respect to patient anatomy and image guidance accuracy can be used to assess the effectiveness of any system for minimally invasive cochlear implantation, on both an individual patient and wider population level. BACKGROUND: Minimally invasive cochlear implantation involves the drilling of a tunnel from the surface of the mastoid to cochlea, with the trajectory passing through the facial recess. The facial recess anatomy constrains the drilling path and places prohibitive accuracy requirements on the used system...

Intracranial abscesses are rare complications of Streptococcus pneumoniae infections, and to our knowledge, there have been no case reports of post-infectious vasculitis developing in such patients. Here we describe the case of a 48-year-old post-splenectomy male who developed post-infectious vasculitis following S. pneumoniae otitis media complicated by mastoiditis, osteomyelitis, meningitis, and intracranial abscess. Clinicians ought to be aware of the possible adverse outcomes of invasive S. pneumoniae and the limitations of current treatment options...

BACKGROUND: Brain abscess is an uncommon but life-threatening infection. It involves a focal, intracerebral infection that begins in a localized area of cerebritis and develops into a collection of pus, surrounded by a well-vascularized capsule. Brain abscess still poses a significant problem in developing countries but rarely in developed countries. Predisposing factors vary in different parts of the world. With the introduction of antibiotics and imaging studies, the mortality rate has decreased between 5% and 15%...

Outcome Objectives To (1) explore audiometric outcomes following use of a combined transmastoid/middle cranial fossa (TM-MCF) approach in the treatment of spontaneous cerebrospinal fluid (CSF) otorrhea and (2) determine the influence of dehiscence location and reconstructive methodology on audiometric outcomes. Study Design Case series with chart review. Setting Tertiary care center. Subjects and Methods Adults with spontaneous CSF otorrhea were reviewed from 2007 to 2016 if they underwent combined TM-MCF. Definitive audiometric evaluations were performed at least 3 months postoperatively...

OBJECTIVES: Dissection of cadaveric temporal bones (TBs) is considered the gold standard for surgical training in otology. For many reasons, access to the anatomic lab and cadaveric TBs is difficult for some facilities. The aim of this prospective and comparative study was to evaluate the usefulness of a physical TB prototype for drilling training in residency. DESIGN: Prospective study. SETTING: Tertiary referral centre. PARTICIPANTS: Thirty-four residents were included...

Vestibular disorders are difficult to diagnose early due to the lack of a systematic assessment. Our previous work has developed a reliable experimental design and the result shows promising results that vestibular sensory input while walking could be affected through mastoid vibration (MV) and changes are in the direction of motion. In the present paper, we wanted to extend this work to older adults and investigate how manipulating sensory input through mastoid vibration (MV) could affect dynamic postural control during walking...

We conducted a retrospective chart review to characterize the outcomes of 12 patients-9 men and 3 women, aged 21 to 79 years (mean: 49)-who had been treated at our tertiary care center for acute bacterial meningitis caused by acute otitis media (ABMAO). Fever was the most common presenting sign/symptom, observed in 8 patients, followed by otalgia, neck stiffness, headache, and confusion. An opaque and bulging tympanic membrane was observed in 8 patients. Cultures were positive for Streptococcus pneumoniae in the cerebrospinal fluid, ear, and blood in 7, 5, and 3 patients, respectively...
