Recognizing Decompensated Meniere's Disease Using High Frequency Rotational Test.

Objectives: The purpose of this study is to investigate the effectiveness of the high-frequency rotational test for discrimination of patients with decompensated from those with compensated Meniere's disease.

Materials And Methods: Patients with unilateral Meniere's disease were divided into two groups (compensated and decompensated), based on the presence of clinically significant positional nystagmus as a determinant of the compensation status. All patients and subjects underwent pure tone audiometry, video nystagmography, and the vestibular autorotation test (VAT).

Neurofibroma around the Ear Canal: Report of Three Cases.

Facial nerve neurofibromas are an uncommon entity, particularly in the intraparotid region. Three cases are presented herein, including the first reported case of both an intratemporal and intraparotid facial nerve malignant neurofibroma. To the best of our knowledge, this is the first medical publication to describe a neurofibroma involving both the intratemporal and intraparotid regions.

The examination revealed a herniating temporomandibular joint into the right external auditory meatus when the patient closed his mouth.

Relationship between nasal valve changes and nasalance of the voice.

Objective: It is well known that the nasal cavity and paranasal sinuses affect the acoustic characteristics of the voice as resonators. Any expansion in nasal valve area, the narrowest segment of the nasal cavity, affects the nasal resistance and therefore has the potential to alter the nasalance. The aim of this study was to investigate the effect of nasal valve changes on nasalance of the voice by using an external nasal dilator strip that widens the nasal valve area.

Protein profiling of anastomosed facial nerve treated with mesenchymal stromal cells.

Background Aims: The types of proteins released from mesenchymal stromal cells (MSC) are still unclear. Our aim was to compare apoptosis scores and the expression of myelin-associated glycoprotein (MAG), myelin basic protein (MBP), neural cell adhesion molecule (NCAM)-1,matrix metalloproteinase (MMP)-1A, tissue inhibitor of metalloproteinase (TIMP)-1, TIMP-1/MMP-1A ratio, nerve growth factor (NGF), brain-derived neurotrophic factor (BDNF), ciliary neurotrophic factor (CNTF), neurotrophin (NT)-3, NT-4, glial cell-derived neurotropic factor (GDNF), leukemia inhibitory factor (LIF), basic fibroblast growth factor (FGF)-2, insulin-like growth factor (IGF)-1, platelet-derived growth factor (PDGF)-α and transforming growth factor (TGF)-β1 in anastomosed facial nerves that had been treated with or without MSC.

Methods: In seven rats, the buccal branch of the right facial nerve was transected, anastomosed and treated with MSC (anastomosed + MSC group).

Castleman disease as a giant parapharyngeal mass presenting with dysphagia.

A giant unilateral parapharyngeal mass from the skull base to the vocal folds is presented in this case. A 20-year-old man experiencing dysphagia for 4 years was admitted, and his magnetic resonance imaging and computed tomographic scans showed a giant parapharyngeal ellipsoid mass from the left jugular foramen to the vocal folds. Its craniocaudal length was 9 cm.

In both groups, tumor incidence that had been noticed on routine postoperative histopathologic examination was recorded retrospectively.

Temporomandibular joint herniation into the external ear canal through foramen of Huschke.

Foramen of Huschke, which is also known as the foramen tympanicum, is an anatomical variation of the tympanic portion of the temporal bone. This foramen is located on the anteroinferior aspect of the external auditory canal, posteromedial to the temporomandibular joint. Herein, a rare case of foramen Huschke with a herniation of the soft tissues around the temporomandibular joint that result in severe otalgia and its treatment are presented.

Endoscopic transnasal transpterygoid approach for parasphenoidal myxoma.

The parasphenoidal region is a difficult location to gain access to and contains a lot of vital neurovascular structures that have risk of injury during surgery. The transnasal endoscopic approach for this region has been described in several cadaveric studies in recent years. Herein we present a case of parasphenoidal myxoma, extending to the anteroinferior border of the cavernous sinus in a 48-year-old woman.

Temporalis fascia and cartilage-perichondrium composite shield grafts for reconstruction of the tympanic membrane.

Objectives: We sought to compare the long-term functional results of tympanic membrane reconstruction with temporalis fascia and cartilage shield grafting.

Methods: This study includes 113 patients who had tympanoplasty type I tympanic membrane reconstruction between 1997 and 2007, 47 with tragal cartilage and 66 with temporalis fascia. Fourteen patients in the cartilage group and 9 patients in the temporalis fascia group also had mastoidectomy.

New morphometric findings in adhesive otitis media: petroclival angle and eustachian tube-tympanic cavity ventilation angle.

Objective: Observations during adhesive otitis media (OM) surgery led us to consider that morphometric variations might cause formation of the middle ear cavity with smaller bony boundaries during developmental process. Among the various factors mentioned in the literature, we thought that angle of the petrous bone relative to the midsagittal line and the eustachian tube-tympanic cavity ventilation angle might be factors in the course of adhesive otitis media.

Methods: Axial computerized tomography scans from 14 patients with adhesive OM and 19 cases (control group) with normal middle ear-tympanic membrane were retrospectively examined in terms of petroclival angle and eustachian tube-tympanic cavity ventilation angle.

Efficiency of Stenger test in confirming profound, unilateral pseudohypacusis.

Objective: Conscious and deceptive exaggeration of hearing loss is termed pseudohypacusis. Even though the Stenger test has been used in the management of pseudohypacusis for almost a century, its sensitivity, specificity and predictive values for unilateral pseudohypacusis have not previously been reported, to our best knowledge. We investigated the efficiency of the Stenger test in detecting unilateral pseudohypacusis, accepting auditory brainstem response testing as the 'gold standard'.
