Objectives: . Facial nerve sacrifice during radical parotidectomy can impair quality of life. This study assessed the effectiveness of single-stage facial reanimation surgery performed concurrently with radical parotidectomy in restoring facial function. Methods: . A retrospective analysis was conducted on patients who underwent single-stage facial reanimation combined with radical parotidectomy. The techniques employed included selective reinnervation and orthodromic temporalis tendon transfer. Outcomes were evaluated using the modified House-Brackmann and Terzis grading systems, Emotrics facial assessment, and the Facial Disability Index (FDI). Results: . Among the 13 patients studied (median age, 54 years; 69% male), 10 underwent selective reinnervation. Of these, nine patients demonstrated improvement, achieving House-Brackmann grade III and Terzis grade 4 or 5. The other three patients underwent tendon transfer and achieved moderate functional outcomes. Emotrics analysis revealed balanced facial symmetry in the selective reinnervation group. Furthermore, FDI scores indicated satisfactory physical and social/well-being functions. Conclusion . Single-stage facial reanimation effectively restores facial function in patients undergoing radical parotidectomy. This approach offers meaningful benefits in the early recovery of facial function.

Purpose: Diffuse large B-cell lymphoma (DLBCL) is the most common hematologic malignancy worldwide. Although substantial improvement has been achieved by the frontline rituximab-based chemoimmunotherapy, up to 40%-50% of patients will eventually have relapsed or refractory disease, whose prognosis is extremely dismal. Materials and Methods: We have carried out two prospective cohort studies that include over 1,500 DLBCL patients treated with rituximab plus CHOP (#NCT01202448 and #NCT02474550). In the current report, we describe the outcomes of refractory DLBCL patients. Patients were defined to have refractory DLBCL if they met one of the followings, not achieving at least partial response after 4 or more cycles of R-CHOP; not achieving at least partial response after 2 or more cycles of salvage therapy; progressive disease within 12 months after autologous stem cell transplantation. Results: Among 1,581 patients, a total of 260 patients met the criteria for the refractory disease after a median time to progression of 9.1 months. The objective response rate of salvage treatment was 26.4%, and the complete response rate was 9.6%. The median overall survival (OS) was 7.5 months (95% confidence interval, 6.4 to 8.6), and the 2-year survival rate was 22.1%±2.8%. The median OS for each refractory category was not significantly different (p=0.529). Conclusion In line with the previous studies, the outcomes of refractory DLBCL patients were extremely poor, which necessitates novel approaches for this population.

BACKGROUND: The basophil activation test (BAT) is a promising tool for monitoring allergen-specific immunotherapy responses. OBJECTIVE: We aimed to investigate the changes in basophil activation in response to the inhalant allergens of house dust mite (HDM) and mugwort pollen during immunotherapy in patients with allergic rhinitis. METHODS: We enrolled patients with allergic rhinitis who were to receive subcutaneous immunotherapy for the inhalant allergens HDM or mugwort. A BAT was performed to assess CD63 upregulation in response to allergen stimulation using peripheral blood collected from the patients prior to immunotherapy and at 3, 6, 12, and 24 months after beginning immunotherapy. Rhinitis symptoms were evaluated using the rhinitis quality of life questionnaire (RQLQ) at 1-year intervals. RESULTS: Seventeen patients (10 with HDM sensitivity, 3 with mugwort sensitivity, and 4 with sensitivity to both HDM and mugwort) were enrolled in the study. Basophil reactivity to HDM did not change significantly during 24 months of immunotherapy. However, a significant reduction in basophil reactivity to mugwort was observed at 24-month follow-up. There was no significant association between the change in clinical symptoms by RQLQ and the change in basophil reactivity to either allergen. The change in allergen-specific basophil reactivity to HDM was well correlated with the change in nonspecific basophil activation induced by anti-FcεRI antibody, although basophil reactivity to anti-FcεRI antibody was not significantly reduced during immunotherapy. CONCLUSION: Suppression of CD63 upregulation in the BAT was only observed with mugwort at 2-year follow-up. However, the basophil response did not reflect the clinical response to immunotherapy.

OBJECTIVE: Recently, the survival of patients with hepatocellular carcinoma (HCC) has been prolonged with improvements in various diagnostic tools and medical treatment modalities. Consequently, spine metastases from HCC are being diagnosed more frequently. The accurate prediction of prognosis plays a critical role in determining a patient's treatment plan, including surgery for patients with spinal metastases of HCC. We investigated the clinical features, surgical outcomes, and prognostic factors of HCC presenting with spine metastases, in patients who underwent surgery. METHODS: A retrospective review was conducted on 33 HCC patients who underwent 36 operations (three patients underwent surgical treatment twice) from February 2006 to December 2013. The median age of the patients was 56 years old (range, 28 to 71; male : female=30 : 3). RESULTS: Overall survival was not correlated with age, sex, level of metastases, preoperative Child-Pugh classification, preoperative ambulatory function, preoperative radiotherapy, type of operation, administration of Sorafenib, or the Tokuhashi scoring system. Only the Tomita scoring system was shown to be an independent prognostic factor for overall survival. Comparing the Child-Pugh classification and ambulatory ability, there were no statistically differences between patients pre- and post-operatively. CONCLUSION: The Tomita scoring system represents a practicable and highly predictive prognostic tool. Even though surgical intervention may not restore ambulatory function, it should be considered to prevent deterioration of the patient's overall condition. Additionally, aggressive management may be needed if there is any ambulatory ability remaining.

OBJECTIVES: The purpose of this study was to evaluate the therapeutic effect of three different types of sounds on tinnitus patients undergoing tinnitus retraining therapy (TRT). METHODS: This is a single-institution retrospective study, performed in one tertiary otological referral center. Thirty-eight adults with subjective idiopathic tinnitus who were followed for at least 9 weeks were enrolled. Sound therapy was delivered in 3 different ways: narrowband noise TRT (nTRT); mixed band noise TRT (mTRT); broadband noise TRT (bTRT). Treatment response was measured through validated psychometric questionnaires: Tinnitus Handicap Inventory (THI), visual analog scale (VAS) on annoyance, and numerical description of hours of tinnitus perception (awareness hours). RESULTS: A total of 38 patients were followed for at least 9 weeks. In nTRT group, all outcome measures including THI, VAS, and the awareness hours, decreased over 9 weeks with no statistical significance. In mTRT group, all outcome measures except for awareness hours significantly improved 9 weeks after the beginning of the treatment. In bTRT group, all outcome measures decreased significantly in 9 weeks. When therapeutic success is defined as improvement in THI 7 or more, bTRT group (77.8%) showed a higher success rate than other groups for 38 patients with the minimum follow-up of 9 weeks. CONCLUSION: All three sounds can provide relief in patients with annoying tinnitus after TRT. However, there is difference in the therapeutic effect according to sound types. Broadband sound seems to be better than narrowband sound or mixed sound in relieving the patients from tinnitus. Therefore, sound therapy with broadband noise may be more appropriate during TRT, but further evidence is needed for precise conclusion.

BACKGROUND AND OBJECTIVES: According to previous reports, patients with vestibular migraine (VM) display variable results from vestibular function tests (VFT): central, peripheral, or normal. The aim of this study was to classify the VM patients into the three groups according to interictal VFT findings (central, peripheral or normal) and to clarify the relationship between VFT results and the clinical manifestations and prognosis in each group. SUBJECTS AND METHODS: We reviewed the medical records of 81 patients diagnosed as VM using the criteria of Neuhauser, et al. between December 2004 and June 2009. Patients were divided into three groups according to the results of VFT. We compared the clinical manifestations and prognosis between groups. Characteristics including dizziness, the nature of headache, associated otologic symptoms, hearing threshold, duration of illness, and recovery time were analyzed. RESULTS: The number of patients with central, peripheral vestibular dysfunction and normal finding in VFT were 15, 28, and 38 respectively. There were no significant differences in the nature of headache, associated otologic symptoms, hearing threshold, duration of illness, and recovery time. A small difference was observed in the mean age and characteristics of dizziness, but these were not significant. CONCLUSIONS: In patients with VM, classification according to the type of vestibular dysfunction was not helpful in the prediction of prognosis and clinical manifestations.

BACKGROUND AND OBJECTIVES: Eosinophilic otitis media (EOM) is characterized by the presence of a highly viscous effusion containing eosinophils. It mainly occurs in patients with bronchial asthma, nasal polyps and is resistant to conventional treatments for otitis media. In these patients, steroid is very effective in controlling the disease. However, the major complication is sensorineural hearing loss, especially at high frequencies, which may occur despite steroid therapy. SUBJECTS AND METHOD: Here we report 10 cases of EOM at Seoul National University Hospital. Clinical courses and characteristics of the patients were analyzed. We compared the hearing deterioration and other clinical variables between EOM patients and age-matched non-EOM chronic otitis media patients. RESULTS: All cases had viscous effusion and 9 cases were associated with asthma and nasal polyps. All patients had a decreased hearing in high frequency range compared to the age matched controls. The average bone conduction threshold difference at 2 kHz, 4 kHz was 22.4 dB HL and 42.5 dB HL, respectively. Among the patients, one showed profound sensorineural hearing loss bilaterally after the onset of EOM and received cochlear implantation. The open set sentence score was 82% 6 months after cochlear implantation. Most of the cases were resistant to conventional treatments for otitis media, such as administration of antibiotic agents, ventilation tube insertion or mastoidectomy. However, cases that were given steroid treatment had improvement in ear symptoms. CONCLUSION: Since EOM patients show deterioration of hearing, it is important to properly diagnose EOM, start adequate treatment and explain to patients that the disease may last for a long period and progressive hearing loss may occur.

BACKGROUND AND OBJECTIVES: It is necessary to establish the most efficient diagnostic and therapeutic method for benign paroxysmal positional vertigo (BPPV), which is appropriate for Korean healthcare system. We aimed to evaluate current state of Korean clinician's diagnostic and therapeutic approaches for BPPV. MATERIALS AND METHODS: A 16-item survey was emailed to the members of dizziness department of Otology Research Interest Group in the Korean Otologic Society (n=68). 43 were returned and analyzed. RESULTS: All respondents (100%) used Dix-Hallpike test as a diagnostic tool for vertical canal-BPPV. Supine roll test was used for diagnosing lateral canal BPPV in nearly all the respondents (97.7%). Epley maneuver was chosen as otolith repositioning maneuver (ORM) for posterior canal BPPV in all respondents and barbecue rotation (BBQ) was used for treating lateral canal BPPV with geotropic nystagmus in 95.3% of respondents. Extreme variation was noted for therapeutic approach of lateral canal BPPV with ageotropic nystagmus BBQ, with 4 kinds of ORM and adjunctive measures to liberate otolith from cupula, while BBQ was again the most commonly used ORM (76.7%). CONCLUSION: The development of practical and efficient ORM for lateral canal BPPV with ageotropic nystagmus is necessary.

BACKGROUND AND OBJECTIVES: Although the adverse effect of long term steroid usage is well known, the adverse effect of short term high dose steroid usage has not been studied thoroughly. The purpose of this study was to identify the characteristics of the adverse effects when using a high dose steroid for a short term. We also compared the adverse effect of steroid between in- and out-patients. SUBJECTS AND METHODS: The medical record of 500 patients, who were treated with methylprednisolone 48 mg/day for 1-2 weeks, was retrospectively reviewed. Steroid was prescribed due to SSNHL, Bell's palsy, Ramsay-Hunt syndrome and herpes zoster oticus. The incidence of each adverse effect was analyzed, and also the time point of detection was analyzed. The 500 patients were composed of 250 in-patients and 250 out-patients. The adverse effect was compared between these two groups, as well. RESULTS: Adverse effect of steroid was found in 33.0% of the patients. Among these adverse effects, abdominal discomfort (26.8%) was most common, followed by skin rash (14.7%), swelling (13.4%), and hot flush (6.9%). Abdominal discomfort and hot flush was mostly detected on the first week. Meanwhile, the skin rash was usually detected on the third week. The incidence of adverse effect was significantly higher in the out-patient group. CONCLUSIONS: The incidence of high dose short term steroid treatment may be very high. The patients should be warned about these adverse effects. Monitoring should be performed until 3-4 week, since some adverse effects may not be detected until this time point.
