External auditory canal reconstruction with inferior pedicled square screw flap from the preauricular area after resection of external auditory canal cancer.

BACKGROUND: The postoperative reconstruction of ear canal cancer with a local flap such as the snail flap technique has been reported for cases with few tissue defects. The snail flap technique requires a large skin incision and is at risk of facial neuropathy. We have devised a new flap that addresses these problems. METHODS: An 80-year-old woman underwent total right ear canal resection for cancer of the right ear canal, and the defect of the ear canal was reconstructed using a local flap. The local flap was used by making a rectangular incision in front of the auricle and rolling it into a cylindrical shape. We named this flap a square screw flap. RESULTS: The patient was discharged 1 week after surgery without complications. CONCLUSIONS: This method is considered to be useful for reconstruction of the ear canal with a small defect.

Clinical Diagnosis of Central Vertigo in Patients With Dizziness in Emergency Practice.

BACKGROUND: Life-threatening diseases should be promptly identified to provide appropriate medical care for emergency outpatients experiencing dizziness. However, dizziness is associated with various medical conditions; thus, a definitive diagnosis is challenging. To accurately diagnose vertigo in an emergency outpatient, we conducted a survey on the need to identify vertigo patients in the current outpatient departments. MATERIALS AND METHODS: The participants included 509 patients who visited the outpatient department at our hospital from February 2014 to May 2017. Overall, 12 characteristics were retrospectively extracted from the patients' medical records: age, sex, visit method, medical history (diabetes, hypertension, cardiac, or cerebrovascular disease), dizziness history, vertigo characteristics, concomitant symptoms, systolic blood pressure, nystagmus, imaging history, diagnosis, and hospitalization department. Univariate and multivariate analyses were performed to identify factors related to central vertigo. RESULTS: The diagnosis of central vertigo was confirmed when intracranial lesions were detected through imaging. In multivariate analysis, the presence/absence of a history of headache and cardiovascular disease were significantly correlated with central vertigo (P=0.002 and 0.006, respectively), with odds ratios of 5.18 and 4.38, respectively. CONCLUSIONS: To avoid missing central dizziness in a patient, diagnostic abilities should be improved by including careful interviews and confirmation of the presence/absence of accompanying symptoms. Furthermore, collaboration with neurology and neurosurgery departments is important for improving the diagnosis in suspected cases.
