    Recurrent pleomorphic adenoma: is treatment considerably delayed thus affecting surgical morbidity?
    Acta Otolaryngol 2017 Nov 16:1-4. Epub 2017 Nov 16.
    a Department of Otolaryngology, Head and Neck Surgery , the Sheba Medical Center , Tel-Hashomer , Israel.
    Objective: To examine the incidence of late presentation of patients with recurrent pleomorphic adenoma (RPA) of the parotid gland.

    Methods: This is a retrospective analysis of patients treated in our center. We examined patients demographics, disease characteristics, treatment, and outcome and as well as the time period length from the first discovery of a recurrent mass until seeking treatment at our clinic and its effect on morbidity.

    Utility of quick oculomotor tests for screening the vestibular system in the subacute and chronic populations.
    Acta Otolaryngol 2017 Nov 16:1-5. Epub 2017 Nov 16.
    f NASA/Johnson Space Center , Neuroscience Research Laboratories , Houston , TX , USA.
    Objective: The goal of this study was to determine the sensitivity and specificity of some widely used, easily administered clinical tests.

    Background: Simple tests of oculomotor function have become widely used for clinical screening of patients suspected of having vestibular disorders despite a paucity of evidence showing good statistical support for their use in this highly variable population.

    Methods: Healthy controls with no history of otologic or neurologic disorders (n = 291) were compared to patients with known vestibular disorders (n = 62). Read More

    Necessity of admission to improve the hearing-recovery rate in idiopathic sudden sensorineural hearing loss.
    Acta Otolaryngol 2017 Nov 13:1-6. Epub 2017 Nov 13.
    a Department of Otorhinolaryngology-Head and Neck Surgery, College of Medicine , Hallym University , Chuncheon , Republic of Korea.
    Objectives: The purpose of this study was to determine the prognostic potential of admission of a patient for idiopathic sudden sensorineural hearing loss (ISSNHL).

    Study Design: Retrospective clinical study.

    Methods: We conducted a retrospective study of 301 patients with ISSNHL. Read More

    Optical assessment of the in vivo tympanic membrane status using a handheld optical coherence tomography-based otoscope.
    Acta Otolaryngol 2017 Nov 10:1-8. Epub 2017 Nov 10.
    a School of Electronics Engineering, College of IT Engineering , Kyungpook National University , Daegu , Korea.
    Objective: Conventional otoscopes and oto-endoscopes, which are used to examine the tympanic membrane (TM), do not provide tomographic information. Optical coherence tomography (OCT) non-invasively reveals the depth-resolved internal microstructure of the TM with very high spatial resolution. We designed this study to examine the TMs with middle ear diseases using a handheld otoscope employing 860 nm spectral domain (SD)-OCT, combined with video camera and to demonstrate the clinical applicability of this system.

    Value of extranodal extension detected by computed tomography for predicting clinical response after chemoradiotherapy in head and neck squamous cell cancer.
    Acta Otolaryngol 2017 Nov 6:1-8. Epub 2017 Nov 6.
    a Department of Otolaryngology, Asan Medical Center , University of Ulsan College of Medicine , Seoul , Republic of Korea.
    Objectives: Radiological extranodal extension (rENE) upon CT is obtained before concurrent chemoradiation therapy (CCRT) for head and neck squamous cell carcinoma (HNSCC). We evaluated the prognostic value of rENE, rather than pathologically proven ENE, in patients who received CCRT for HNSCC.

    Materials And Methods: We reviewed 117 patients. Read More
