Bilateral sudden sensorineural hearing loss following COVID-19 infection has rarely been reported. We encountered a 34-year-old patient with bilateral profound sensorineural loss after COVID-19 infection. After disappointing therapeutic result of high dose steroid therapy and intratympanic steroid injection, the patient experienced satisfactory auditory rehabilitation with bilateral cochlear implantation.

Nasal lymphoma is an uncommon neoplasm in the sinonasal tract. The NK/T-cell type of lymphoma is more commonly found in Asian populations. However, B-cell lymphoma is more common in the western countries whereas it is rare in Asia. Recently, we experienced two cases of sinonasal B-cell lymphoma, which are rare cases in Korea, one in an advanced stage and one in an early stage. Both patients had no specific nasal symptoms or systemic B symptoms (fever, night sweat, weight loss). As our cases demonstrate, diagnosis of B cell lymphoma is often delayed in many cases because B-cell lymphoma does not show any specific symptoms. Thus, careful physical examination and biopsy under suspicion of malignancy are important for early diagnosis of nasal lymphoma.

Inverted papilloma (Schneiderian-type papilloma) involving the middle ear is extremely rare. Most of cases originate from the mucosa of the lateral nasal wall, extending into the paranasal sinuses and orbits. Inverted papilloma involving the middle ear has a high recurrence rate and a possibility of malignant change. We experienced a case of inverted papilloma of the middle ear secondary to congenital cholesteatoma surgery. A nine-year old male who was diagnosed with congenital cholesteatoma was treated with intact canal wall tympanomastoidectomy. Nine months later, he underwent a second look operation. In the second surgery, a 3 mm round pinkish mass which was located at the tympanic orifice of Eustachian tube was identified as inverted papilloma. There was no recurrence of cholesteatoma or inverted papilloma four months after the 2nd operation.

Background and Objectives: We investigated the clinical validity of and correlation between the Eustachian Tube Dysfunction Questionnaire-7 (ETDQ-7) scores and the eustachian tube function test (ETFT) results in patients with a normal drum. Subjects and Methods: The study included 49 patients (93 ears) with unilateral or bilateral ear fullness over >3 months. All patients were administered the ETDQ-7 survey and underwent the ETFT on the same day. The receiver operating characteristic (ROC) curve and the association between the results were statistically analyzed. Results: ETDQ-7 scores were not significantly correlated with the ETFT results or with middle ear pressure. ETDQ-7 scores in patients with eustachian tube dysfunction (ETD) were significantly higher than those in patients with normal ETFT results (p=0.039) when ETD was defined as a pressure change <10 daPa on the ETFT. The area under the ROC curve was 0.631, with a sensitivity of 37.0% and specificity of 89.4%. Conclusions The ETDQ-7 has limited clinical significance in patients with ETD but a normal drum. Therefore, concomitant objective tests should be performed to diagnose patients with ETD.

BACKGROUND AND OBJECTIVES: Video head impulse tests (vHITs) and caloric tests are widely used to assess the loss of vestibular function in acute vestibular neuritis. Although previous studies have reported on the results of each test, longitudinal comparison of these tests is rare. In the present study, vHITs and caloric tests were performed in patients with unilateral vestibular neuritis during the acute phase and after a long follow-up period (>6 months). The goal of this study was to evaluate the changes in vHIT and caloric test results and to analyze the relationships between them. SUBJECTS AND METHOD: Between September 2013 and December 2015, charts from 13 patients with unilateral vestibular neuritis were retrospectively reviewed. Among the 13 patients, caloric tests and vHITs were performed in 9 and 10 patients, respectively. Results of the vHITs and caloric tests were analyzed and the changes were compared. RESULTS: During the acute phase of vestibular neuritis, the results of the caloric test showed an increase in canal paresis (CP), and the results of the vHIT showed a decrease in horizontal gain. Although subjective symptoms improved in all patients after a long follow-up period (mean: 13.9 months), the occurrence of CP determined from the caloric test was not significantly changed (p=0.889). On the other hand, the mean horizontal gain of the vHIT had improved significantly (p < 0.05). CONCLUSION: While CP determined from the caloric test did not change after a long follow-up period, the decreased horizontal gain in the vHIT was significantly recovered in patients with unilateral vestibular neuritis.
