María Carmen Bravo, Eva Valverde
BACKGROUND: Cerebellar size appears to be correlated with the long-term outcome of preterm infants. Two-dimensional cranial ultrasonography (2D-cUS) is the first-line, routine tool to characterize newborn cerebral structures. Information regarding the accuracy of 2D-cUS for assessing cerebellar size is scarce. OBJECTIVES: To assess the reliability of cerebellar size using 2D-cUS. METHODS: Fifty infants were prospectively scanned for a variety of clinical indications...

PURPOSE: The study was designed to assess correlations between intraoperative findings in revision tympanomastoidectomy as predictors of cholesteatoma recurrence. MATERIALS AND METHODS: A retrospective single-institution cohort of 101 patients who underwent surgical treatment for recurrent chronic otitis media in a tertiary referral otology centre. RESULTS: Out of 101 patients, 65 had canal wall up and 36 canal wall down revision surgery. There were 35 cholesteatoma recurrences...

CONCLUSION: Patients with mastoiditis and chronic suppurative otitis media which has small mastoids that make them ideal candidates for modified canal wall down mastoidectomy (MCWD) which contributes to a dry and spacious ear and the maintaining and improving hearing. OBJECTIVES: To evaluate surgical outcomes for chronic otitis media underwent MCWD. METHODS: A clinical retrospective study was performed on 47 ears with chronic otitis media which has relatively limited attic lesions have the small, sclerotic and hypocellular mastoids according to the preoperative high-resolution CT scan of the temporal bone that underwent MCWD and 32 ears with typical canal wall down operation form January 2010 to January 2016...

OBJECTIVE: Making a 3-dimensional (3D) temporal bone model is simple using a plaster powder bed and an inkjet printer. However, it is difficult to reproduce air-containing spaces and precise middle ear structures. The objective of this study was to overcome these problems and create a temporal bone model that would be useful both as a training tool and for preoperative simulation. METHODS: Drainage holes were made to remove excess materials from air-containing spaces, ossicle ligaments were manually changed to bony structures, and small and/or soft tissue structures were colored differently while designing the 3D models...

OBJECTIVE: To investigate the influence of two different electrode montages (ipsilateral: reference to mastoid and vertical: reference to nape of neck) to the ABR results recorded using a level-specific (LS)-CE-Chirp® in normally hearing subjects at multiple intensities levels. DESIGN: Quasi-experimental and repeated measure study designs were applied in this study. Two different stopping criteria were used, (1) a fixed-signal averaging 4000 sweeps and, (2) a minimum quality indicator of Fmp = 3...

OBJECTIVE: The prevalence of incidental temporal bone disease on magnetic resonance imaging has been widely reported in the medical literature. Despite this, there currently is little evidence regarding incidental otological disease on computerized tomography (CT). Thus, the study aimed to review the CT prevalence of asymptomatic adult ear disease and evaluate the appropriateness of ear, nose, and throat (ENT) referral following its discovery. STUDY DESIGN: Retrospective observational study of 468 CT scans...

Transcranial pulsed current stimulation (tPCS) is a neuromodulatory technique that has been studied in the last decade. Several parameters have been assessed independently to optimize the effects. Our aim was to explore the effects of tPCS using different montages on cortical brain oscillations indexed by power spectrum and interhemispheric coherence in different electroencephalography frequency bands. Twenty healthy individuals were randomized to receive either active tPCS or sham intervention using the following bilateral montages: ear clip (conventional), ear hook, or mastoid placement...

INTRODUCTION: The lenticular process of the incus succumbs to necrosis in chronic otitis media. Few researchers have addressed the issue of autograft incus preservation in the soft tissue of the tragus or mastoid cavity. Nonetheless, preservation of the incus in this method during the second stage of ossiculoplasty is a subject that is still up for debate. This study was carried out to demonstrate the hearing outcome after a modification of the incus interposition technique, which involved preserving it in the periauricular soft tissue...

Mastoid obliteration has been performed with various materials including muscle, fat, cartilage, musculoperiosteal flaps, chips and pâté(1) . Biocompatible materials used since the 1960s, have a number of potential advantages over autologous tissue. They are sterile, available off the shelf without the need for harvest and have a low risk of implanting cholesteatoma.

Introduction After mastoidectomy, patients usually complain of bone depressions in the retroauricular region in the surgical site, especially in procedures that require extensive cortical resections. This causes inconveniences such as difficulty wearing glasses, cleaning, and aesthetics complaints. Objective This study aims to describe a vascularized flap surgical technique that uses the mastoid cortical bone adhered to the periosteum, which is pedicled on the anterior portion and repositioned at the end of the surgery...

Radiological findings of Dyke-Davidoff-Masson syndrome (DDMS) in patients with different etiologies are presented in our study. The study included 12 patients (seven females, five males) for whom radiological examinations were requested due to reasons such as epilepsy, mental retardation, and/or hemiplegia. CT was performed in 12, MRI in 6, MRA in 1, and DSA in 1 patient. Following imaging findings were evaluated: cerebral and cerebellar involvement (laterality, encephalomalacia), affected territories, ventricular enlargement, sulcal enlargement, calvarial thickening, and paranasal sinus enlargement hyperaeration...

BACKGROUND AND PURPOSE: The standard head CT protocol makes detection of a temporal bone fracture difficult. The purposes of our study are to revisit the finding of air in various locations around the temporal bone as an indirect sign of fracture and determine if findings could predict fracture pattern. MATERIALS AND METHODS: We searched the radiology reports for the keyword "temporal bone fracture." We recorded the presence of air in multiple locations around the temporal bone and pneumocephalus, opacification of the mastoid air cells or the middle ear cavity, and dominant fracture pattern...

When acute mastoiditis occurs in cochlear implant recipients, it can progress to subsequent retroauricular abscess due to the absence of the external mastoid cortex resulting from mastoidectomy performed for cochlear implantation. The management goal is to control infection while preserving the implanted device. A 2-year-old boy with cochlear implants developed acute mastoiditis and a subsequent retroauricular abscess. The patient underwent a surgical intervention based on the diagnosis made utilizing gray-scale and power Doppler sonography...

There is mounting evidence of a link between the properties of electroencephalograms (EEGs) of depressive patients and the outcome of pharmacotherapy. The goal of this study was to develop an EEG biomarker of antidepressant treatment response which would require only a single EEG measurement. We recorded resting 21-channel EEG in 17 in-patients suffering from bipolar depression in eyes-closed and eyes-open conditions. The EEG measurement was performed at the end of a short washout period which followed previous unsuccessful pharmacotherapy...

Introduction.Moraxella nonliquefaciens is an unusual organism to be isolated from cerebral spinal fluid (CSF) and there exists only one case report of M. nonliquefaciens meningitis from a neonate. Moraxella species normally exist as part of the human upper respiratory tract flora and rarely cause invasive human disease. There are only a handful of case reports implicating the organism as a cause of endocarditis, bacteraemia, septic arthritis and endophthalmitis. Identification to the species level based on routine laboratory techniques has been challenging, with final identification often made through 16S rRNA sequencing...

OBJECTIVE: To investigate the clinical significance of vibration-induced nystagmus (VIN) in unilateral vestibular asymmetry and vestibular schwannoma. METHODS: Thirteen patients with vestibular schwannoma underwent the VIN test, in which stimulation was applied to the mastoid processes and sternocleidomastoid (SCM) muscles on the ipsilateral and contralateral sides of lesions. Preoperative VIN was measured, and changes in VIN were followed up for 6months after tumor removal...
