Treatment of Scapula Fractures of the Inferior Angle Causing Pseudowinging Scapula / 대한정형외과학회잡지

Nonoperative treatment of scapular body fractures has shown good clinical results. Although scapula fractures of the inferior angle, particularly with oblique lines from the medial proximal to lateral distally, are very rare, we believe that such a fracture pattern would be regarded as an avulsion fracture of the serratus anterior muscle requiring surgery. We have experienced three cases demonstrating pseudowinging of the scapula due to displacement of the inferior angle fracture of the scapula. Surgical repair or plating showed satisfactory clinical results. Through these cases, we describe the cause of winging scapula and the problems resulting from an avulsion fracture of the serratus anterior muscle with a review of the relevant literature and explain the reason that an operation is needed for this fracture pattern.

A Case of Arachnoid Cyst Presenting with Sudden Hearing Loss / 대한이비인후과학회지

Arachnoid cysts compose 1% of all intracranial tumors and are usually incidental findings in brain imaging. They may present with symptoms such as dizziness, tinnitus and hearing loss, although they may be usually asymptomatic. In particular, presentation with sudden deafness is very rare. We report a case of a 21-year-old male who presented with sudden hearing loss linked to a cerebellopontine angle (CPA) arachnoid cyst. In this case, the cystic lesion at the CPA was found by magnetic resonance imaging of the brain. The hearing loss of this patient was successfully treated with steroids.

Vestibular Function Test of Dizziness Patients by Vestibular Evoked Myogenic Potential / 대한평형의학회지

BACKGROUND AND OBJECTIVES: Because the saccule, next to the cochlea, is the second most frequent site of hydrops formation, we evaluated whether vestibular evoked myogenic potential (VEMP) responses can reflect the diagnosis and the stage of Meniere's disease. And we studied about other vestibular disease such as vestibular neuritis and benign paroxysmal positional vertigo. MATERIALS AND METHODS: Retrospectively, we analyzed the results of VEMP in 22 patients (12 men and 10 women) with unilateral definite Meniere's disease, 21 patients (5 men and 16 women) with vestibular neuritis, and 23 patient (4 men and 19 women) with benign paroxysmal positional vertigo (BPPV). All subjects underwent VEMP testing using ipsilateral 1 KHz-tone burst sound with 105 dB nHL. RESULTS: VEMP was present in 86% of Meniere affected ear. The latency of p13 of affected ears in patients with Meniere's disease, vestibular neuritis (VN), BPPV was not significantly prolonged than that of normal ears in the control group except left n23 latency in meniere's disease. In the patients with Meniere's disease, the amplitude-ratio was larger than that of the control group, statistically (p=0.006). And relationship was found in amplitude ratio among groups classified by the stage of Meniere's disease. CONCLUSION: This study shows that amplitude ratio of VEMP response is useful method to determine the severity and prognosis of Meniere's disease. We recommend VEMP to explain to the patient about severity of Meniere's disease quantitatively.
