Vertigo symptom scores and videonystagmographic examinations in recovered coronavirus disease 2019 patients.

OBJECTIVE: Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) may be among the viral agents that affect the audio-vestibular system. This study aimed to investigate vestibular symptoms and videonystagmographic examinations in recovered coronavirus disease 2019 (Covid-19) patients compared with the control group. METHOD: The patients were evaluated with Vertigo Symptom Scale questionnaire and audiometric, tympanometric, stapedial reflex and videonystagmographic examinations. RESULTS: A total of 92 of the patients in the coronavirus disease 2019 patients group and 25 of the volunteers in the control group were included in the study. The mean Vertigo Symptom Scale score was found to be significantly higher (p < 0.001) in the coronavirus disease 2019 group. Furthermore, one of the hospitalised patients was diagnosed with vestibular neuritis. CONCLUSION: The vestibular system may also be affected in some coronavirus disease 2019 patients. Although this may be seen as dizziness in some patients, in rare cases it can cause severe issues, such as vestibular neuritis.

Detection of recurrent and primary acquired cholesteatoma with echo-planar diffusion-weighted magnetic resonance imaging.

OBJECTIVE: To evaluate the diagnostic value of echo-planar diffusion-weighted magnetic resonance imaging in pre-operative detection of suspected primary acquired, residual and/or recurrent cholesteatoma. MATERIALS AND METHODS: Fifty-eight chronic otitis media patients with suspected cholesteatoma were thus evaluated two weeks pre-operatively, and divided into group one (41 patients, no previous surgery, suspected primary acquired cholesteatoma) and group two (17 patients, previous surgery, scheduled 'second-look' or revision surgery for suspected residual or recurrent cholesteatoma). Patients' operative, histopathology and radiological findings were compared. RESULTS: Cholesteatoma was found in 63 per cent of group one patients and 58 per cent of group two patients at surgery. Histopathological examination of surgical specimens indicated that imaging accurately predicted the presence or absence of cholesteatoma in 90 per cent of group one (37/41; 23 true positives, 14 true negatives) and 76 per cent of group two (13/17; seven true positives, six true negatives). Three patients in both groups were false negative diagnoses and one patient in both groups was a false positive. The sensitivity, specificity, and positive and negative predictive values of echo-planar diffusion-weighted magnetic resonance imaging of cholesteatoma were respectively 88, 93, 95 and 82 per cent in group one and 70, 85, 87 and 66 per cent in group two. CONCLUSION: Echo-planar diffusion-weighted magnetic resonance imaging is a valuable technique with high sensitivity and specificity for cholesteatoma imaging.

Endovascular embolization of intermittent massive epistaxis secondary to posttraumatic carotid artery pseudoaneurysms.

Epistaxis is a very common medical problem in otolaryngology practice and can usually be controlled with conservative interventions. Rarely, uncontrolled and life threatening epistaxis occurs. We present the case of a 29-year-old male who developed intractable intermittent epistaxis due to post-traumatic pseudoaneurysms arising from the cavernous segment of the left internal carotid artery. The patient was successfully treated with endovascular embolization.
