OBJECTIVES: To evaluate the necessity of preserving the posterior branch of the great auricular nerve during parotidectomy. STUDY DESIGN AND SETTING: Forty-six patients undergoing parotidectomy were prospectively analyzed. Twenty-four patients had preservation of the posterior branch of the great auricular nerve; in the remaining 22 patients the nerve was sacrificed. A sensory index score was defined as the area involved multiplied by the intensity grade of sensory loss. Quality-of-life was eval

OBJECTIVE: To investigate the clinical significance of cardiovascular factors, including arterial stiffness and metabolic syndrome scores, in the development of vestibular neuritis. STUDY DESIGN: A prospective, case-control study. SETTING: Tertiary referral center. PATIENTS: Fifty-eight adult patients with vestibular neuritis (VN) and 58 age- and sex-matched controls were evaluated between January 2015 and January 2016. INTERVENTION: Measurement of arterial stiffness. MAIN OUTCOME MEASURES: Arte

Intratympanic steroid injection might be a safe and useful adjuvant treatment modality for Bell's palsy.

Osteoradionecrosis of the temporal bone is a very rare but potentially lethal complication of radiotherapy for head and neck or skull base tumors. Only two cases of osteoradionecrosis of the temporal bone complicating cerebrospinal fluid (CSF) otorrhea have been reported in the literature. This report describes a case of CSF otorrhea and osteoradionecrosis of the temporal bone in a patient with meningioma who was treated with tympanomastoid surgery and autologous fat obliteration in the mastoid.

This study was conducted to determine the effect of supplementation of Zn to fish meal diets on growth of Japanese eel. The feeding experiments were carried out using white fish meal diets supplemented with 0, 50, 100, and 200μ g/g of Zn as Zinc sulfate (ZnSO4•anhydrous). The results revealed that the fish on diet annexed with 50 and 100μ g/g of Zn were observed to have the high growth among these groups.Eel fed a diet without supplementation of Zn caused a high value of condition factor (19, 0)

Telomerase activity was positive in 21/40 cholesteatomas (52.5%), but absent in the control group. The average Ki-67 labeling index in the cholesteatoma group was 32.84+/-10.13, higher than that in the control group (21.83+/-7.76) (p<0.05). The average Ki-67 labeling indices of the 21 telomerase activity-positive and 19 telomerase activity-negative cholesteatomas were 37.76+/-8.53 and 27.39+/-9.06, respectively. The Ki-67 labeling index was significantly higher in telomerase-positive cholesteato

We develop a guideline for rating the physical impairment of otolaryngologic fields. Assessment of hearing disturbance and tinnitus required physical examination, pure tone audiometry, speech audiometry, impedance audiometry, brainstem evoked response audiometry, Bekesy audiometry, otoacoustic emission test, and imaging examination. History taking, physical examination, and radiological examination for the vestibular organ and brain, righting reflex test, electronystagmography, and caloric test

Feeding study was conducted to determine the quantitative requrements of Al and Fe, and to examine the interrelationship with the other minerals in the Japanese eel Anguilla japonica. The experimental diets used were those based on white fish meal supplemented with 0, 15, 30, 50, 75, and 100μg/g of Al as aluminum chloride and 0, 100, 150, 200, 300, and 400μg/g of Fe as ferrous sulfate. The fish on diet supplemented with 15μg/g level of Al showed the best growth among all groups. In case of Fe, t
