A Case of Cerebellopontine Angle Osteoma Causing Sudden Hearing Loss with Vertigo / 대한평형의학회지

Osteomas arising from the internal auditory canal (IAC) and locating in the cerebellopontine angle (CPA) are rare. These tumors may cause compression of the IAC with varying degree of hearing loss, vertigo, and tinnitus but sometimes asymptomatic. Here we present a 60-year-old female patient presented with a hearing loss of sudden onset in her right ear and recurrent dizziness of whirling type. Magnetic resonance imaging and computed tomography revealed CPA osteoma arising from the porus of the IAC. Osteomas should be considered as differential diagnosis in patients with sudden hearing loss and vertigo.

Functional Benefit after Modification of Radial Forearm Free Flap for Soft Palate Reconstruction

OBJECTIVES: To compare the velopharyngeal function, swallowing and speech of the conventional and modified radial forearm free flap (RFFF) for soft palate reconstruction. METHODS: Retrospective clinical study. Twenty-eight patients who underwent oropharyngeal reconstruction with RFFF were divided into two groups: 10 patients had conventional folded RFFF and 18 patients underwent modified method. RESULTS: The average speech intelligibility score in modified RFFF group was 8.0+/-2.4, and 6.2+/-2.2 in conventional RFFF group (P<0.05). The nasalance was 27.4+/-7.8% in modified group and 38.6+/-2.7% in conventional group during no nasal passage reading and 43.6+/-7.3% in modified group, 55.2+/-7.6% in conventional group during high nasal passage reading (P<0.05). The subjective swallowing functional score was 2.8 in modified group and 2.1 in conventional group. CONCLUSION: The speech assessment and nasalance demonstrate a more favorable outcome in modified group than conventional group.
