Abstract
OBJECTIVE To assess the annual incidence of vestibular neuritis (VN) in the Japanese population. METHODS We conducted a mail-based survey targeting otolaryngologic clinics and hospitals across Japan to estimate the annual number of patients who were newly-diagnosed with VN during the one-year period of 2021. Using a stratified sampling method, we selected 1,107 departments and asked them to report the number of new patients with VN and their demographics. The total number of VN patients was estimated by multiplying the reported numbers by the reciprocal of the sampling rate and response rate. RESULTS The overall survey response rate was 40.5 % (448 departments). The estimated number of newly-diagnosed VN patients in 2021 was 8,861 (95 % confidential interval [CI], 2,290-15,432) The annual incidence of VN was 7.05 per 100,000 population in Japan. The male-to-female ratio of VN patients was 0.96, and the mean age was 60.3 ± 16.1 years (range 11-94 years). CONCLUSIONS The annual incidence of VN in Japan in 2021 had almost doubled and the mean age had become older compared to the previous study in 1993 (annual incidence; 3.5 per 100,000 per year; mean age: 45 years).

Abstract
OBJECTIVE In the present study, we examined the effects of high-dose betahistine on dizziness handicap inventory (DHI) scores in patients with unilateral vestibulopathy. METHODS An uncontrolled, open-label, multicenter clinical trial was conducted. Fifteen patients with unilateral vestibulopathy, such as vestibular neuritis, who complained of intractable dizziness for more than three months were enrolled. Initially, all patients were orally administered betahistine at a dose of 36 mg/day for four weeks, which is the standard dose and dosing period for the treatment of dizziness in Japan. The patients were then administered betahistine at a double dose of 72 mg/day for four weeks. Six patients who became aware of the benefits of high-dose betahistine were further administered betahistine at 72 mg/day for an additional 12 weeks (a total of 16 weeks). Perceived disability due to dizziness was assessed by DHI scores. RESULTS In all 15 patients, short-term administration with high-dose (72 mg/day) betahistine for four weeks, but not low-dose betahistine (36 mg/day) for four weeks significantly decreased DHI scores. In particular, in six responding patients with self-reported benefits after short-term administration with high-dose betahistine, long-term administration with high-dose betahistine for 16 weeks further significantly decreased DHI scores. However, DHI scores of the remaining nine non-responding patients were not changed after short-term administration with high-dose betahistine for four weeks. CONCLUSION Short-term administration with the standard dose and dosing period of betahistine did not improve DHI scores in the enrolled patients, indicating that they were not compensated for unilateral vestibulopathy with intractable dizziness. The present findings suggest that long-term administration with high-dose betahistine facilitates vestibular compensation to improve intractable dizziness in some, but not all patients with uncompensated unilateral vestibulopathy.

Abstract
OBJECTIVE To provide diagnostic and therapeutic strategies for vestibular neuritis in accordance with the Japanese Clinical Practice Guidelines for Vestibular Neuritis 2021. METHODS The Committee for Clinical Practice Guidelines for Vestibular Neuritis was entrusted with a review of the relevant scientific literature on the above topic. Clinical Questions (CQs) concerning the treatment of vestibular neuritis were produced, and a search of the literature was conducted to identify studies related to the CQs. The recommendations were based on the literature review and the expert opinion of a subcommittee. RESULTS We proposed the diagnostic criteria for vestibular neuritis, as well as answers to CQs, recommendations, and evidence levels for the treatment of vestibular neuritis. CONCLUSION The diagnostic criteria for vestibular neuritis were based on clinical history and examination findings after completing the differential diagnosis process. The treatment of vestibular neuritis was divided into acute, subacute, and chronic stages. The Japanese Clinical Practice Guidelines for Vestibular Neuritis 2021 should be used as a reference in the diagnosis and treatment of vestibular neuritis.

Abstract
BACKGROUND Long-term efficacy of middle ear pressure therapy (MEPT) with the EFET01 device in patients in Japan with definitive Ménière's disease (MD) and delayed endolymphatic hydrops (DEH) was evaluated. OBJECTIVE To examine the effects of reducing vertigo attacks and improving hearing of MD and DEH patients by using MEPT with the EFET01 device for two years after treatment. MATERIAL AND METHODS A retrospective study was conducted of 32 MD patients and 2 DEH patients treated by MEPT with the EFET01 device from December 2018 to April 2021. According to Japan Society for Equilibrium Research (JSER) guidelines, patients were investigated for the frequency of vertigo attacks and change in hearing levels during a period of 6 months before to 18-24 months after start of treatment. RESULTS The frequency of vertigo attacks significantly decreased in both MD and DEH patients, and hearing level has remained stable in the majority of our patients after treatment. CONCLUSION Our study clarified that MEPT with the EFET01 device was effective in controlling vertigo symptoms of MD and DEH. It should be considered a safe option for patients failing medical treatment. SIGNIFICANCE The efficacy of MEPT with the EFET01 was shown over a 2-year follow-up period.

Abstract
BACKGROUND As a low-cost, portable, handheld air pressure generation tool not requiring a ventilation tube, the EFET01 device has shown clinical effectiveness for intractable Ménière's disease (MD) patients in Japan. However, no animal studies have investigated changes in inner ear pressure (PI) when applying this device. OBJECTIVE To determine the PI properties in response to middle ear pressure therapy (MEPT) induced by the EFET01 in guinea pigs. MATERIAL AND METHODS In seven healthy guinea pigs, bi-phasic pressure pulses from -5 to 12 cm H2O were delivered to the external ear canal and transmitted to the middle and inner ear cavities with an intact tympanic membrane. Hydrostatic pressure change in the inner ear perilymphatic compartment was measured by a servo-controlled micropipette system. RESULTS From eight successful ears, pressure changes in the middle ear slightly decreased and were instantly transferred to the inner ear. The EFET01 produces a bi-phasic positive/negative pressure pulse, which is approximately twice as large as the monophasic pressure pulse. CONCLUSION Our study clarified the EFET01's ability to transmit pressure and verified its effectiveness in MD patients as observed in clinical studies. SIGNIFICANCE The PI properties in guinea pig response to MEPT with the EFET01 device were investigated.

Abstract
BACKGROUND Delayed endolymphatic hydrops (DEH) is a rare disease, and the actual number of patients in Japan remains unknown. OBJECTIVE To investigate the number and prevalence of patients with DEH in Japan. METHODS In total, 781 departments of otolaryngology in Japan were selected for survey by stratified random sampling according to the total number of hospital beds. We sent questionnaires to the target departments and collected data regarding the number of patients with DEH who visited those departments in 2019. RESULTS The overall response rate was 68.0% (531 departments). The estimate number of patients with DEH in Japan was 962, and the prevalence was calculated to be 0.8 per 100,000 population. CONCLUSION Patients with DEH were extremely rare in Japan. SIGNIFICANCE This may be the first nationwide epidemiological study on the number and prevalence of patients with DEH in Japan or in the world.

Abstract
BACKGROUND Delayed endolymphatic hydrops (DEH) is an inner ear disease that causes recurrent vertigo in the ipsilateral ear or fluctuating hearing in the contralateral ear due to endolymphatic hydrops secondary to preceding deafness. There are few reports of large, multicentre studies investigating the clinical-epidemiological characteristics of DEH. OBJECTIVE This study aimed to clarify the characteristics of DEH in Japan. METHODS Clinical data on 662 patients with DEH were analysed by nationwide, multicentre surveys conducted by the Peripheral Vestibular Disorders Research Group of Japan. RESULTS The proportion of ipsilateral DEH (IDEH) was slightly higher than that of contralateral DEH (CDEH) at 55.4%. The time delay between onset of precedent deafness and onset of DEH was significantly longer for CDEH than for IDEH. The most common cause of precedent deafness was a disease of unknown cause with onset in early childhood (33.1%). Epidemiological characteristics were not significantly different between CDEH with and without vertigo. CONCLUSION DEH appearing to be caused by viral labyrinthitis has a high rate of onset within 40 years of precedent deafness. Clinical and epidemiological characteristics of IDEH, CDEH with vertigo, and CDEH without vertigo were very similar. SIGNIFICANCE The clinical-epidemiological characteristics of DEH in Japan were clarified.

Abstract
BACKGROUND Middle ear pressure therapy (MEPT) is effective for intractable vertigo in patients with definite Meniere's disease (MD) and treatment-refractory delayed endolymphatic hydrops (DEH). Four-month MEPT with the EFET01®, an MEPT device developed in Japan and covered by national health insurance since September 2018, has shown efficacy. However, efficacy and safety after 12 months of treatment, which is appropriate for determining the therapeutic effect of MEPT devices, is unclear. OBJECTIVES Examine the therapeutic effect of 12-month MEPT using the ETET01®. MATERIAL AND METHODS Patients underwent MEPT using the EFET01® from September 2018 to July 2021. Thirty-three patients followed for >12 months were enrolled in this retrospective study. Clinical data were evaluated in the first and second 6-month treatment periods. Data from the second 6-month period were compared with data from an MEPT study using a different device. RESULTS MEPT with the EFET01® significantly improved vertigo in the first period, with further improvement in the second period. The efficacy and safety were comparable to MEPT with other devices. CONCLUSIONS MEPT with the EFET01® is effective for intractable vertigo in patients with definite MD and DEH, and 12-month follow-up is recommended. SIGNIFICANCE The efficacy of 12-month MEPT with the EFET01® was demonstrated.

Abstract
Background Endoscopic modified medial maxillectomy (EMMM) is a surgical technique developed to approach maxillary sinus lesions, such as papilloma and postoperative maxillary cyst, while preserving the postoperative nasal morphology and nasal function. In this technique, a diamond burr is used to remove the bone, which may damage adjacent soft tissue. We developed EMMM using an ultrasonic bone aspirator (UBA) instead of a conventional diamond burr. The purpose of this study was to clarify the effectiveness of the UBA in EMMM in comparison to the conventional diamond burr technique in terms of operative time, intraoperative complications, postoperative symptoms, and recurrence. Methods The medical records of all patients who underwent EMMM at Toyama University Hospital between June 2014 and December 2021 were reviewed. Patients who met the inclusion criteria were separated into Group 1, in which the UBA was used for EMMM, and Group 2, in which a drill with a diamond burr was used. Data on patient demographics, operation time, frequency of intraoperative complications and postoperative symptoms, and recurrence were statistically compared between the two groups. Results There were no significant differences between the two groups in the patient demographic data, operative time, postoperative symptoms, or frequency of recurrence. The frequency of intraoperative damage to adjacent soft tissues was significantly lower in patients who underwent EMMM with the UBA in comparison to those who underwent EMMM with a conventional diamond burr. Conclusion The application of the UBA to EMMM can improve surgical safety and facilitate surgical procedures.

Abstract
BACKGROUND Middle ear pressure therapy (MEPT) is effective in treating intractable vertigo in patients with definite Meniere's disease (MD) and delayed endolymphatic hydrops (DEH) refractory to conservative treatment. A novel middle ear pressure device, the EFET01®, which requires no transtympanic ventilation tubes, was developed in Japan, approved by the Japanese Ministry of Health, Labour and Welfare, and has been used under Japanese national health insurance since September 2018. OBJECTIVES To examine short-term therapeutic effect of MEPT using the ETET01® compared with previous clinical trial results. METHODS Patients selected according to Japan Society for Equilibrium Research (JSER) guidelines underwent MEPT using the EFET01 from September 2018 to July 2021, and 44 patients were enrolled in this retrospective study. Clinical data analysed at 4 months after the start of MEPT were compared with those of the previous clinical trial for the EFET01. RESULTS MEPT using the EFET01 showed the same therapeutic efficacy as that of the previous clinical trial, i.e. improvement in the intensity and frequency of vertigo with no effect on hearing, even under JSER guidelines for proper use of MEPT. CONCLUSION MEPT using the EFET01 provided an effective treatment option for intractable vertigo in patients with definite MD and DEH.

Abstract
BACKGROUND In the external dacryocystorhinostomy (DCR), a sutured anastomosis technique performed between the nasal mucosal and lacrimal sac flaps reported by Dupuy-Dutemps and Bourguet was the gold standard and was believed to lead to the success of the surgery. However, because of the small working space, a flap suturing technique has not been completely established in endonasal DCR (END-DCR). OBJECTIVES The effect of the modified flap suture anastomosis technique using a Sonopet ultrasonic bone aspirator was retrospectively compared to that using a diamond burr in patients with nasolacrimal duct obstruction. MATERIALS AND METHODS One hundred ten patients underwent the modified flap suturing technique using the Sonopet, and 30 patients were operated on using a diamond burr. RESULTS Successful patency of the lacrimal ostium (LO) was obtained in all patients in both groups. The rates of successful suturing during the operation and of a large diameter of the LO 3 months after the operation were significantly higher in patients in whom the Sonopet rather than the burr was used. CONCLUSIONS AND SIGNIFICANCE The Sonopet might offer similar surgical outcome to the traditional microdrill DCR and is a safer means of bone removal in END-DCR in the small working space.

Abstract
Amyloidosis is a disorder of protein folding in which various proteins automatically aggregate into a highly abnormal fibrillar conformation. Amyloidosis is classified into systemic and localized forms depending on whether the abnormal proteins deposited in several different organs or only a single organ. In localized amyloidosis of the head and neck regions, laryngeal amyloidosis is common; however, localized amyloidosis of the nose is extremely rare. We herein report a case of localized amyloidosis of the nose and review the relevant literature on localized sinonasal amyloidosis. A 41-year-old man presented with a history of severe nasal obstruction, which had persisted for two decades. Nasal endoscopy and imaging studies showed extensive thickening of the bilateral nasal mucosa and diffuse submucosal deposition of calcification. After histopathological and systemic examinations, he was diagnosed with localized amyloidosis of the nasal mucosa. Septoplasty and bilateral inferior turbinoplasty, which consisted of mucosal resection using an ultrasonic bone curette, was performed and his symptoms markedly improved. Localized sinonasal amyloidosis has a good prognosis and surgical resection should be selected as a first-line treatment; however, clinicians should recognize the high probability of recurrence.

Abstract
BACKGROUND A 12-month follow-up study showed that middle ear pressure treatment with a transtympanic membrane massage (TMM) device had a similar effect to a Meniett device. OBJECTIVES The effects of pressure treatment with a TMM device were retrospectively compared to the effects of treatment with a Meniett device in patients with Meniere's disease (MD) and delayed endolymphatic hydrops (DEH) who were followed for a minimum of 24 months. MATERIALS AND METHODS Twenty-seven patients were treated with the TMM device and 14 patients were treated with a Meniett device. The insertion of a transtympanic ventilation tube was necessary for the Meniett device but not for the TMM device. RESULTS In patients treated with the TMM and Meniett devices, the frequency of vertigo significantly improved at 19-24 months after treatment. The distribution of vertigo at 19-24 months after treatment did not differ between the patients treated with the two types of devices. Pressure treatment for 8 months or more was suitable to achieve remission. CONCLUSIONS AND SIGNIFICANCE Middle ear pressure treatment for 8 months or more with a TMM or Meniett device was equally effective and provided minimally invasive treatment options for intractable MD and DEH.

Abstract
BACKGROUND The retrospective study showed that the effect of the middle ear pressure treatment by the tramstympanic membrane massage (TMM) device was similar to that of the Meniett device. OBJECTIVES The new TMM device named EFET device was prospectively evaluated in patients with Meniere's disease (MD) and delayed endolymphatic hydrops (DEH) and we compared the effects to the Meniett device. MATERIALS AND METHODS 23 ears of 19 patients were treated with an EFET device, and 17 ears of 15 patients were treated with the Meniett device. All patients suffering from intractable MD and DEH were treated for 4 months. The insertion of a transtympanic ventilation tube was necessary for the Meniett device, but not the EFET device. RESULTS In patients treated by the EFET and Meniett devices, the frequency of vertigo significantly improved after treatment. The distribution of vertigo outcomes at 4 months after treatment did not differ between patients treated with the both devices. CONCLUSIONS AND SIGNIFICANCE Middle ear pressure treatment by the EFET device is effective and provides minimally invasive options for intractable MD and DEH like the Meniett device.

Abstract
OBJECTIVE To assess the prevalence and annual incidence of bilateral vestibulopathy (BV) diagnosed in the Japanese adult population. METHODS We conducted a mail-based survey targeting otolaryngologic clinics and hospitals across Japan to estimate the annual number of patients who were diagnosed as having bilateral vestibulopathy after vestibular function tests during a 12-month period ending March 2019. Using a stratified sampling method, we selected 1,106 departments and asked them to report the number of patients with BV and their demographics. The total number of patients was estimated by multiplying the reported numbers by the reciprocal of the sampling rate and response rate. RESULTS The overall survey response rate was 51.4% (568 departments). The estimated number of patients diagnoses with BV in 2018 was 1,063 (95% confidential interval [CI], 127-1,998) which included 407 patients (95% CI: 134-680) newly-diagnosed with BV. The prevalence and annual incidence of BV in Japan were 0.84 and 0.32, respectively per 100,000 population in Japan. The male-to-female ratio of BV patients was 1.29, and the mean age was 63.7 ± 16.4 years (range 18-84 years). The most frequent etiologies of BV were Meniere's disease (11.4%), meningitis (3.4%), and ototoxic agents (3%). CONCLUSIONS Patients who were diagnosed as having BV were extremely rare in Japan.

Abstract
Background: The clinical usefulness of concurrent chemoradiotherapy before surgery in the treatment of primary, locally advanced sinonasal low-grade, non-intestinal type adenocarcinoma (LG non-ITAC) is unclear. Methods: We present the first case report of the efficacy of super-selective intra-arterial cisplatin (CDDP) infusion concurrent with conventional fractionated radiotherapy (RT) for LG non-ITAC in a Japanese patient. Results: A white, rugged-marginal mass that was histopathologically diagnosed as LG non-ITAC occupied the right nasal cavity. Based on the imaging findings, including computed tomography, magnetic resonance imaging, and positron emission tomography, the tumor was diagnosed as T4aN0M0, stage IVa. After treatment, the nasal tumor disappeared leaving only a small bulge in the medial wall of the middle turbinate. The patient also underwent right transnasal ethmoidectomy performed as salvage surgery. A histopathological examination revealed that the lesion was replaced by granulation tissue with lymphocytic infiltration and hemosiderin-laden macrophages, and no viable tumor cells remained. In the seven years after treatment, the patient has not experienced any local recurrence or regional or distant metastasis. Conclusions: Super-selective intra-arterial CDDP infusion concurrent with conventional fractionated RT followed by salvage surgery might be useful for the management of sinonasal LG non-ITAC.

Abstract
Thyroid-like low-grade nasopharyngeal papillary adenocarcinoma (TL-LGNPPA) is an extremely rare neoplasm of the nasopharynx. Accordingly, its clinical and pathological characteristics are not well-known. We report a case of TL-LGNPPA and review the relevant literature on TL-LGNPPA. A 38-year-old Japanese woman presented with a history of nasal obstruction that had persisted for 1 month after symptoms of a common cold (e.g., low-grade fever, sore throat, and fatigue). A pedunculated tumor of ~20 mm in diameter was found on the posterior edge of the nasal septum. The tumor was endoscopically resected. Based on careful histopathological and immunohistochemical examinations, it was diagnosed as TL-LGNPPA. At 5 years after surgery, the patient remained disease-free. TL-LGNPPA has a very good prognosis, and complete resection with a sufficient safety margin is recommended as the first-line treatment. The morphological characteristics and immunohistochemical findings, especially TTF-1 positivity and thyroglobulin negativity, are important for the diagnosis.

Abstract
Objective: To provide information on the clinical characteristics and management of an uncommon acquired nasolacrimal drainage system obstruction (NLDSO). Methods: A patient was treated with microdebrider-assisted endoscopic marsupialization for a cystic lesion located in the synechiae between the inferior turbinate and the lateral wall of the inferior meatus. Results: A 21-year-old woman suffered from epiphora and purulent discharge 1 week after inferior turbinate surgery. Endoscopy reveled synechiae between the inferior turbinate and the lateral wall of the inferior meatus. Computed tomography-dacrocystography (CT-DCG) showed enlargement of the nasolacrimal duct and cystic accumulation of contrast medium from the lacrimal orifice posteriorly. The patient was treated with nasal endoscopic marsupialization of the cyst and then powered inferior turbinoplasty. Six months after the operation, both endoscopy and CT scan showed a widely patent left inferior meatus and nasolacrimal orifice. Conclusions: We report the first case of post-operative NLDSO following inferior turbinate surgery. Nasal endoscopy and CT-DCG are useful to diagnose the location of a NLDSO. Otorhinolaryngologists should be aware that surgery may lead to the formation of a NLDSO and that endoscopic marsupialization is a curative treatment for these distal-end NLDSO. NLDSOs are caused by synechiae, which are a complication of inferior turbinate surgery.

Abstract
OBJECTIVE We provided diagnostic and therapeutic strategies for Meniere's disease in accordance with Japanese Clinical Practice Guideline of Meniere's disease and delayed endolymphatic hydrops 2nd ed. Tokyo: Kanehara Shuppan; 2020 edited by the Japan Society for Equilibrium Research. METHODS The Committee for Clinical Practice Guidelines was entrusted with a review of the scientific literature on the above topic. Clinical Questions (CQs) concerning the treatment for Meniere's disease were produced, and the literature according to each of them including CQ was searched. The recommendations are based on the literature review and the expert opinion of a subcommittee. RESULTS Diagnosis criteria of Meniere's disease are classified into Meniere's disease with typical cochlear and vestibular symptoms, and atypical Meniere's disease with either cochlear symptoms or vestibular symptoms. Treatment of Meniere's disease was composed of lifestyle changes, medications such as anti-vertigo drugs and diuretics, middle ear positive pressure treatment, and selective destruction of the vestibule. CONCLUSION Meniere's disease is diagnosed based on clinical histories and examination findings after processes of differential diagnosis. Treatment option of the disease should be selected in order of invasiveness, according to the severity of the disease and the response to each treatment.

Abstract
Sensory conflict among visual, vestibular, and somatosensory information induces vertiginous sensation and postural instability. To elucidate the cognitive mechanisms of the integration between the visual and vestibular cues in humans, we analyzed the cortical hemodynamic responses during sensory conflict between visual and horizontal rotatory vestibular stimulation using a multichannel near-infrared spectroscopy (NIRS) system. The subjects sat on a rotatory chair that was accelerated at 3°/s2 for 20 s to the right or left, kept rotating at 60°/s for 80 s, and then decelerated at 3°/s2 for 20 s. The subjects were instructed to watch white stripes projected on a screen surrounding the chair during the acceleration and deceleration periods. The white stripes moved in two ways; in the "congruent" condition, the stripes moved in the opposite direction of chair rotation at 3°/s2 (i.e., natural visual stimulation), whereas in the "incongruent" condition, the stripes moved in the same direction of chair rotation at 3°/s2 (i.e., conflicted visual stimulation). The cortical hemodynamic activity was recorded from the bilateral temporoparietal regions. Statistical analyses using NIRS-SPM software indicated that hemodynamic activity increased in the bilateral temporoparietal junctions (TPJs) and human MT+ complex, including the medial temporal (MT) area and medial superior temporal (MST) area in the incongruent condition. Furthermore, the subjective strength of the vertiginous sensation was negatively correlated with hemodynamic activity in the dorsal part of the supramarginal gyrus (SMG) in and around the intraparietal sulcus (IPS). These results suggest that sensory conflict between the visual and vestibular stimuli promotes cortical cognitive processes in the cortical network consisting of the TPJ, the medial temporal gyrus (MTG), and IPS, which might contribute to self-motion perception to maintain a sense of balance or equilibrioception during sensory conflict.

Abstract
RATIONALE Most cases of lymphoepithelial carcinoma (LEC) occur in the nasopharynx, and LEC in the sinonasal tract is extremely rare; thus, the clinical characteristics of sinonasal LEC are not well known. PATIENT CONCERNS A 63-year-old Japanese man presented with a three-week history of left cheek pain, nasal obstruction and cheek swelling. DIAGNOSES Enhanced CT and MRI revealed a tumor of the left maxillary sinus that invaded the left orbit and hard palate, with multiple swollen left cervical lymph nodes. Open biopsy was performed, and the specimen was diagnosed as LEC. INTERVENTIONS Alternating chemoradiotherapy (ALCRT) followed by salvage surgery was performed. OUTCOMES Our patient has been disease free for 5 years. LESSONS A literature review of the epidemiology, etiology, clinical course and management of sinonasal LEC is highlighted. We believe ALCRT followed by salvage surgery to be a highly optimal treatment for sinonasal LEC from the viewpoint of a balance between quality of life and a high curative effect.

Abstract
Stabilometry is a useful tool for examining patients with functional disorders of the vestibular system. However, measurement techniques and devices vary by country. Therefore, international standardization of stabilometry is mandatory to validate the exchange of important findings. This was advocated at the 1983 Posturography Meeting in Kyoto but has not been adopted worldwide, and each country has continued to use unique regional measurement methods. In Japan, stabilometry has widespread application in medical practice in conjunction with research into its applications. With a goal of international standardization, we present details of stabilometry measurement methods and their application in Japan, together with a brief history and potential future directions of stabilometry.

Abstract
OBJECTIVES Using a large-scale nationwide survey database, we investigated the epidemiological characteristics for idiopathic SSNHL in Japan. METHODS The subjects for this analysis were patients registered in a Japanese multicentre database between April 2014 and March 2016. A total of 3419 idiopathic SSNHL patients were registered in the database, and the clinical characteristics of the idiopathic SSNHL patients were obtained. Several factors associated with the severity of hearing impairment and prognosis were then investigated. Statistical analysis was performed to clarify the factors associated with the severity of hearing impairment and prognosis. RESULTS There were significant correlations between the severity of hearing loss and diabetes mellitus, kidney disease, past history of brain infarction, heart disease, age (under 16 years/elderly), and symptoms of vertigo/dizziness. We also analyzed the prognostic factors for idiopathic SSNHL, and found that the severity of hearing loss (Grade 3 or 4), heart disease, aged 65 years or over, time from onset to treatment (over 7 days), and symptoms of vertigo/dizziness were all significantly related to poor prognosis. CONCLUSION The present large-scale clinical survey revealed current epidemiological trends for idiopathic sudden sensorineural hearing loss (SSNHL) and various factors associated with the severity of hearing impairment and prognosis.

Abstract
OBJECTIVES A nationwide epidemiological survey involving 23 hospitals in Japan was conducted and the predictive values of demographic data were examined statistically. METHODS A total of 642 patients from 23 hospitals, including 20 university hospitals, in Japan were enrolled in the study. Age ranged from 8 to 87 years, and all were diagnosed with acute low-tone sensorineural hearing loss (ALHL) between 1994 and 2016. Demographic data for the patients, such as symptoms, gender, mean age, and distribution of ALHL grading, were collected and analyzed in relation to prognosis using Student's t-test, χ2 test and logistic regression. RESULTS Female gender (p < .013), younger age (p < .001), low-grade hearing loss (p < .001), and shorter interval between onset and initial visit (p < .004) were significantly predictive of a good prognosis. The prognosis for definite ALHL was significantly better than that for probable ALHL (p < .007). CONCLUSIONS The severity of initial hearing loss, interval between onset and initial visit and age were important prognostic indicators for ALHL, while female gender was an important prognostic indicator peculiar to ALHL.

Abstract
OBJECTIVES To present the cardiovascular risk factors in idiopathic sudden sensorineural hearing loss (SSNHL) patients enrolled in a nationwide epidemiological survey of hearing disorders in Japan. MATERIALS AND METHODS We compiled the cardiovascular risk factors in 3073 idiopathic SSNHL subjects (1621 men and 1452 women) and compared their proportions with controls as part of the National Health and Nutrition Survey in Japan, 2014. The cardiovascular risk factors consisted of drinking and smoking habits, a history of five conditions related to cardiovascular disease and body mass index. RESULTS The proportion of current smokers was significantly higher among men aged 50-59, 60-69 and 70+ and among women aged 30-39, 40-49 and 60-69. The proportion of patients with a history of diabetes mellitus was significantly higher among men aged 50-59, 60-69 and 70+, but not in women. In addition, male and female SSNHL subjects aged 60-69 showed lower proportions of current drinking; and female SSNHL subjects aged 60-69 showed higher proportions of overweight (BMI ≥25 kg/m2). CONCLUSIONS The present cross-sectional study revealed showed significantly higher proportions of current smokers among both men and women as well as those with a history of diabetes mellitus among men across many age groups in patients with idiopathic SSNHL compared with the controls.

Abstract
OBJECTIVES The aim of this study was to investigate the differences between idiopathic sudden sensorineural hearing loss (SSNHL), and acute low-tone sensorineural hearing loss (ALHL) using the results of a nationwide survey database in Japan and to analyze the variables associated with their clinical features and the severity of hearing impairment, treatment, and prognosis. METHODS Participants were patients registered between April 2014 and March 2016 in a multicenter epidemiological survey database involving 30 university hospitals and medical centers across Japan. Statistical analysis was performed to clarify the factors associated with their clinical characteristics and the severity of hearing impairment, treatment, and prognosis. RESULTS Idiopathic SSNHL and ALHL differed significantly in terms of male-to-female ratio, age distribution, and time from onset to start of treatment. The treatment methods and hearing prognosis also differed markedly between the two diseases. A majority (92%) of idiopathic SSNHL patients were administered some type of corticosteroid, while half of the ALHL patients received corticosteroids and a diuretic agent. CONCLUSION The results suggested that idiopathic SSNHL and ALHL belonged to different categories of inner ear disease.

Abstract
OBJECTIVE To investigate the hearing prognosis of idiopathic sudden sensorineural hearing loss (SSNHL) treated with different initial therapies. METHODS Subjects consisted of patients diagnosed with idiopathic SSNHL within 7 days from onset and showing severe hearing loss (≥60 dB), who were registered in a Japanese multicenter database between April 2014 and March 2016. Subjects were divided into four groups according to initial therapy: (1) steroids, (2) steroids + Prostaglandins (PGs), (3) intratympanic steroids (ITS), and (4) no steroids. Hearing outcomes were compared among the groups. RESULTS In total, 1305 patients were enrolled. The final hearing level and hearing gain of patients treated with steroids + PGs were significantly higher than those of patients treated with steroids alone or no steroids. The ratio of good prognosis (complete recovery or marked improvement) in patients treated with steroids + PGs was higher than that in patients treated with steroids alone or no steroids. There was no difference in the prognosis of patients treated with steroids alone or no steroids. CONCLUSION A large number of patients with idiopathic SSNHL were registered in a multicenter database. PG use in combination with steroid administration was associated with a good hearing prognosis in patients with severe hearing loss.

Abstract
Rhabdomyosarcomas in the parapharyngeal space are quite rare. We report herein on the case of a 14-month-old boy who was hospitalized with a 2-month history of stridor. On admission, right peritonsillar swelling was noted. CT demonstrated the presence of a large tumor in the right parapharyngeal space. MRI findings showed a right parapharyngeal tumor, 6-cm in diameter. Histopathologic evaluation of the tumor revealed embryonal rhabdomyosarcoma. The clinical staging of the Intergroup Rhabdomyosarcoma Study Group (IRSG) was classified as group III. According to regimen 35 of the IRSG III treatment protocol, radiochemotherapy was started, comprising combination therapy with vincristine, actinomycinD, cyclophosphamide, adriamycin, and carboplatin. The patient tolerated the therapy, but with severe pancytopenia and fever. His sedation during irradiation was difficult. After he received a total dose of 10 Gy and had undergone 9 cycles of chemotherapy, an operation for the rhabdomyosarcoma was performed, resulting in successful removal of the tumor. Doses of 20 Gy were intraoperatively administered. After surgery, residual chemotherapy and irradiation was resumed. The evaluation of the response to therapy was complete remission. After 4 years from the start of therapy, all chemotherapy was halted. At present there is no evidence of recurrence or metastasis, and the patient is a well-developed college student. His sequela following therapy consisted of facial asymmetry, dental abnormalities, and pigmentation of the neck. No adriamycin cardiomyopathy was found.

Abstract
To investigate cortical roles in standing balance, cortical hemodynamic activity was recorded from the right hemisphere using near-infrared spectroscopy (NIRS) while subjects underwent the sensory organization test (SOT) protocol that systematically disrupts sensory integration processes (i.e., somatosensory or visual inputs or both). Eleven healthy men underwent the SOT during NIRS recording. Group statistical analyses were performed based on changes in oxygenated hemoglobin concentration in 10 different cortical regions of interest and on a general linear analysis with NIRS statistical parametric mapping. The statistical analyses indicated significant activation in the right frontal operculum (f-Op), right parietal operculum (p-Op), and right superior temporal gyrus (STG), right posterior parietal cortex (PPC), right dorsal and ventral premotor cortex (PMC), and the supplementary motor area (SMA) under various conditions. The activation patterns in response to specific combinations of SOT conditions suggested that (1) f-Op, p-Op, and STG are essential for sensory integration when standing balance is perturbed; (2) the SMA is involved in the execution of volitional action and establishment of new motor programs to maintain postural balance; and (3) the PPC and PMC are involved in the updating and computation of spatial reference frames during instances of sensory conflict between vestibular and visual information.

Abstract
CONCLUSIONS It was shown that practicing with a tangible head model with semicircular canals is a useful educational tool for learning the physical treatment for BPPV. OBJECTIVES To assess the efficacy of using a tangible head model with semicircular canals to teach the physical treatment for BPPV. METHODS This study compared the number of canalith particles in the posterior semicircular canal that 20 participants could move from the ampulla to the utricle, before and after practicing with the tangible model. RESULTS Before practicing with the model, they could move 2.5 (mean value) of 10 canalith particles. However, after practicing, they could move 6.6 (mean value) of 10 canalith particles. There was a statistical difference (p < 0.01) between the two trials.

Abstract
CONCLUSION Endonasal flap suture-dacryocystorhinostomy (eFS- DCR) is a new and valuable technique for the treatment of nasolacrimal duct obstruction (NLDO). This technique could improve the success rate of endonasal DCR in comparison to external DCR. OBJECTIVE The standard procedure for NLDO is DCR. DCR can be performed via either an external or endonasal approach. External DCR is now regarded as the gold standard in the treatment of NLDO because of its higher success rate. However, we report a new endonasal surgical technique, eFS-DCR, and assess its efficacy by comparison with the standard endonasal DCR. METHODS We prospectively investigated a series of 62 consecutive patients with NLDO undergoing endonasal DCR. There were two surgical intervention groups: group 1 (24 patients, 28 sites) undergoing endonasal DCR without eFS; and group 2 (38 patients, 47 sites) undergoing eFS-DCR. Study end points were success rate, the ostium diameter (OD) of the lacrimal sac after DCR, and the duration of stent placement. We compared the two groups on these three points. RESULTS The success rate was 78.6% (22 of 28 sites) for group 1 (DCR without eFS) and 97.9% (46 of 47 sites) for group 2 (eFS-DCR). The ostium size in patients in group 2 was larger than that in group 1. The median time for the duration of stent placement was 42.5 days for group 1 and 31.5 days for group 2. There was a statistical difference (p < 0.01) in all these parameters between the two groups.

Abstract
Objectives: In this study, we developed a tangible head model for the physical treatment of benign paroxysmal positional vertigo (BPPV) and assessed the educational efficacy of this model for people. This model has a 10-time-scale mockup of the semicircular canal, which contains 10 canalith particles, located in a 1.5-time-scale mockup of the head. Methods: This was a prospective study involving 20 medical students just starting to study otolaryngology. At first, they learned the canalith repositioning procedure (CRP) from an article. After reading the article, they tried to move 10 canalith particles from the ampulla to the utricle using the model, during which they were not able to see inside. Second, they practiced the CRP using the model, and they could see the inside. Third, they tried to move 10 canalith particles from the ampulla to the utricle using the model, during which they could not see the inside. Compare the number of canalith particles, which students can move from the ampulla to the utricle, before and after practice using the model. Results: Before practice using the model, they could move 2.5 (mean value) canalith particles, after practice, they could move 6.6 (mean value) canalith particles. There was a statistical difference ( P < .01) between trials before and after practice using the model. Conclusions: It was suggested that a tangible head model for the physical treatment for BPPV is a useful educational tool for people such as resident doctors, medical students, and patients with BPPV.

Abstract
CONCLUSION Fibrin glue might be an inessential bioadhesive for attachment of hyperdry amniotic membrane (AM) patches in canal wall down (CWD) tympanoplasty. OBJECTIVE To clarify the pliability and adherence capability of human hyperdry AM, the feasibility of fixing hyperdry AM without fibrin glue to the bony surface of the mastoid cavity was evaluated in CWD tympanoplasty. METHODS This was a retrospective chart review. In seven ears of seven patients, the AM was simply attached over the bony surface of the mastoid cavity without fibrin glue (AMG(-) group). In 22 ears of 20 other patients, hyperdry AM (11 ears of 11 patients, AMG(+) group) or temporal fascia (11 ears of 9 patients, TFG(+) group) was attached over the bony surface of the mastoid cavity with fibrin glue. Times for graft epithelization were compared among the three groups. RESULTS Complete epithelization of the mastoid cavity took place in all patients in all three groups. The mean time to complete epithelization of the graft in the AMG(-) and AMG(+) groups was significantly faster than that in the TFG(+) group (p < 0.05) and was not significantly different between the two AM groups (p > 0.05).

Abstract
BACKGROUND The prognosis for patients with mucosal malignant melanoma (MMM) of the nasal cavity is very poor because of the radioresistance of melanoma cells. METHODS We present the first case report of the efficacy of superselective intra-arterial cisplatin (CDDP) infusion concurrent with hypofractionated radiotherapy (RT) for MMM of the nasal cavity. RESULTS A pink, polypoid mass, histopathologically diagnosed as an amelanostic melanoma, occupied the right nasal cavity. After the treatment, a nasal tumor disappeared, leaving only a small bulge in the medial wall of the middle turbinate. Histopathologic examination revealed scattered degenerated melanoma cells, remaining only in the small restricted area in the medial surface of the excised middle turbinate. Twelve months after the treatment, the patient has not experienced any local recurrence or regional and distant metastasis. CONCLUSIONS The superselective intra-arterial CDDP infusion concurrent with hypofractionated RT might be useful for the management of nasal MMM.

Abstract
CONCLUSION Middle ear pressure treatment by the tympanic membrane massage (TMM) device as well as the Meniett device is effective and provides minimally invasive options for intractable vertigo in patients with Meniere's disease (MD) and delayed endolymphatic hydrops (DEH). OBJECTIVE The effects of the TMM device were evaluated according to the criteria of the Japan Society for Equilibrium Research (1995) in patients with MD and DEH and compared to those in patients treated with the Meniett device. METHODS Twelve ears of 10 patients (MD 8; DEH 2) were treated with the TMM device, while 16 ears of 15 patients (MD 11; DEH 4) were treated with the Meniett device. All the patients had failed to respond to medical treatment including diuretics before each pressure treatment, and were followed up for more than 12 months after treatment. Tympanotomy is necessary before treatment for the Meniett device, not but for the TMM device. RESULTS With both devices, the frequency of vertigo after treatment was significantly lower than before treatment (p < 0.05). The time course of vestibular symptoms with the TMM device was not significantly different from that with the Meniett device (p > 0.05). No complications were directly attributable to treatment with the TMM device.

Abstract
OBJECTIVES To overcome the lack of the autografts in revision ear surgery, the usefulness of human amniotic membrane (AM) patches as a dressing substitute for fascia grafts of the temporal muscle (temporalis fascia graft) was investigated in canal wall down tympanoplasty. STUDY DESIGN Retrospective chart review. METHODS In 11 ears of 11 patients, the AM was attached over the bony surface of the mastoid cavity (AM group). In 11 ears of nine patients, the temporalis fascia graft was attached over the bony surface of the mastoid cavity (fascia group). The times for graft epithelization were compared in both groups. RESULTS In both groups, complete epithelization of the mastoid cavity took place in all patients. The time of epithelization in the AM group was 32 days, whereas in the fascia group it was 45 days. Complete epithelization of the AM graft was significantly faster than the fascia graft (P < .05). CONCLUSIONS Hyperdry AM might be a new useful dressing substitute for temporalis fascia graft due to the reduction in the epithlializing time offered by the AM in revision ear surgery.

Abstract
We report a 68-year-old female with a history of repeated right cervical lymph node metastasis secondary to eyelid sebaceous carcinoma. She had undergone right neck dissection due to lymph node metastasis at the department of surgery in an other local hospital. After the orbital exenteration, she underwent multiple operations, including 2 right partial parotidectomy and then total parotidectomy, 4 right cervical lymph node excisions and 1 left upper neck dissection due to lymph node metastasis. Adjuvant chemotherapy with S-1(at a dose of 80 mg per day)alone was applied as tumor dormancy therapy on an outpatient basis. Any adverse events during S-1 medication were observed. New metastatic lesions were not found until 29 months after the beginning of chemotherapy with S-1 alone. Although the effectiveness of S-1 for eyelid sebaceous carcinoma has not been demonstrated, S-1 might be useful in patients with recurrent eyelid sebaceous carcinoma based on our patient's recurrence-free survival.

Abstract
CONCLUSION The Meniett device is a minimally invasive and safe treatment that may be used to provide longer-term reduction of vestibular symptoms in patients with delayed endolymphatic hydrops (DEH) as well as those with Meniere's disease (MD). OBJECTIVE The effects of the Meniett device were evaluated in patients with a diagnosis of definite MD or DEH according to the 1995 AAO-HNS criteria. METHODS Twenty-nine ears of 28 patients with MD and 5 ears of 5 patients with DEH (ipsilateral type 4, contralateral type 1) were treated with the Meniett device by the Middle Ear Pressure Treatment Research Group of Japan. All of the patients had failed to respond to medical treatment including diuretics before the pressure treatment. RESULTS Sixteen (57%) patients with MD and all five (100%) patients with DEH remained entirely free from vertigo spells; nine (32%) patients with MD responded with a significant decrease in the frequency of vertigo spells. In regard to hearing, 25 ears (74%: MD, n = 21; ipsilateral DEH, n = 4) had stable hearing levels; only 4 ears (12%: MD, n = 3; contralateral DEH, n = 1) showed a significant hearing improvement. No complications were attributable to the Meniett device.

Abstract
CONCLUSION Similarly to almost all delayed endolymphatic hydrops (DEH) cases with both precedent sudden deafness and mumps deafness, two-thirds of DEH cases with precedent deafness of unknown cause with onset in early childhood developed DEH symptoms within 40 years after the precedent deafness. In spite of the diagnosis of precedent deafness, viral labyrinthitis may build up the late endolymphatic hydrops in most DEH cases up to four decades. OBJECTIVE To clarify the characteristics of DEH in Japan. METHODS Clinical information on 198 DEH cases was collected by nationwide, multicenter surveys conducted by the Peripheral Vestibular Disorders Research Committee of Japan. RESULTS The incidence of the ipsilateral type of DEH was 47.5%, which was almost equal to that of the contralateral type. In both types of DEH, the most common diagnosis of precedent deafness was deafness of unknown cause with onset in early childhood: 43.9% in both types of DEH. Sudden deafness and mumps deafness were the subsequent diagnoses of precedent deafness. The distribution of time delay of the onset between precedent deafness of unknown cause with onset in early childhood and DEH was different from that between precedent sudden and mumps deafness and DEH.

Abstract
Pneumolabyrinth, the presence of air within the labyrinth, is a rare radiologic finding associated with a well-known perilymphatic fistula (PLF). As there are only 24 published case reports in medical literature, multiple treatment options for the pneumolabyrinth are available. We report a case of a 20-year-old man with a pneumolabyrinth secondary to tympanic membrane and ossicular trauma. Despite conservative treatment, sensorineural hearing loss (SNHL) had progressed rapidly, and his profound deafness had not recovered after surgical exploration with closure of the PLF. Functional prognostic factors of SNHL are revised and compared with this case.

Abstract
CONCLUSION The incidence of new cases of Meniere's disease (MD) in elderly patients aged 60 years or more was found to have increased over time after correction for age distribution in the overall population. Job- and care-related fatigue may be involved in the recent increase in elderly-onset cases because physical and mental fatigue can induce onset of the disease. OBJECTIVES Changes over time in the epidemiologic characteristics of MD in Japan were analyzed. MATERIALS AND METHODS Between 1975 and 2006, four nationwide, multi-center surveys of MD were conducted by the Meniere's Disease Research Committee of Japan (1975-1976) and the Peripheral Vestibular Disorders Research Committee of Japan (1982-1984, 1990, and 2001-2006). Information was collected by the committee members on a total of 1368 de novo cases of definite MD, 520 reported in the first survey, 290 in the second survey, 148 in the third survey, and 410 in the fourth survey. RESULTS Clear changes were seen over time in the population-adjusted sex distribution of the disease and population-adjusted age at onset. The number of definite MD cases in females increased over time relative to the number of cases in males. The proportion of cases in which onset occurred at 60 years of age or more increased over time when the number of cases in each age group was adjusted for changes in age distribution of the population over time. From the time of the third survey, there was a slight increase in the proportion of cases with bilateral involvement.

Abstract
We report a case of mumps deafness with acute vestibular symptoms secondary to both retrolabyrinthine and inner ear dysfunction. To our knowledge, no such case has been reported elsewhere. The patient was a 6-year-old girl in whom mumps deafness was initially diagnosed. Two days after onset of the hearing impairment, severe vertigo developed. Neurotologic examinations revealed spontaneous right-beating nystagmus, left canal paresis, absence of vestibular-evoked myogenic potentials in the left ear, and absence of responses to a left galvanic body sway test (GBST). The vertigo resolved 7 days after onset. However, the left hearing impairment progressed to complete deafness. Six months later, left canal paresis was still present, but bilateral GBST responses were normal, suggesting that retrolabyrinthine vestibular function had been restored. Mumps virus may affect retrolabyrinthine function as well as the inner ear.

Abstract
WHAT IS ALREADY KNOWN ABOUT THIS SUBJECT Relationships between smell sensation and autonomic changes have been studied extensively. However, the possibility that odorants may also act on the lung and lower airway remains unknown. WHAT THIS STUDY ADDS The present results provide the first evidence that the lung and lower airway exert an inhibitory influence on the cardiovascular system in response to Cedrol (odorant) in the air under physiological conditions. AIMS Previous studies reported that Cedrol (odorant) inhalation (CI) induced changes in autonomic balance and baroreceptor sensitivity (BRS) in both healthy subjects and anosmic patients. This suggests that Cedrol may act on the lower airway, and that the pulmonary system may exert an inhibitory influence on the cardiovascular system. METHOD To test the above possibility, vaporized Cedrol (64.0 +/- 7.7 10(-9)m) or blank air was directly inhaled through the lower airway from a hole in the trachea, but not through the upper airway, using totally laryngectomized subjects. During the experiment, ECG, systolic (SBP) and diastolic (DBP) blood pressures were measured. Sympathetic and parasympathetic nervous activity was estimated by spectral analyses of variability in these parameters (heart rate variability (HRV), SBP variability (SBPV) and DBP variability (DBPV)). BRS was computed from transfer gain between SBP and the R-R interval of the ECG. RESULTS SBP and DBP significantly decreased during CI, although there were no significant differences in HR and respiratory rate. BRS significantly increased during CI. The low frequency components of SBPV and DBPV (indices for sympathetic activity) significantly decreased during CI, while high frequency components of HRV (an index for parasympathetic activity) significantly increased. CONCLUSIONS The present experiment using totally laryngectomized patients replicated the similar results in healthy subjects who inhaled Cedrol through the nose, suppression of sympathetic outflow and increase in parasympathetic outflow. These results demonstrated that Cedrol acts on the lower airway and pulmonary system, and suggest a new target for drug therapy of hypertension.

Abstract
OBJECTIVE The aim of this study was to elucidate the neural pathway for sound-evoked myogenic potentials (SEMPs) in monkeys with characteristics similar to those of vestibular evoked myogenic potentials in humans. METHODS Six macaque monkeys were examined. The effects of total and selective vestibular nerve section on the SEMPs were evaluated in three monkeys. RESULTS After total vestibular nerve section, the SEMPs and caloric nystagmus were eliminated, and the auditory brainstem response remained. After selective superior vestibular nerve section, the SEMPs remained, but caloric nystagmus was eliminated. CONCLUSIONS The inferior vestibular nerve comprises a neural pathway for SEMPs in monkeys. SIGNIFICANCE SEMP in monkeys may provide a model of human VEMPs.

Abstract
BACKGROUND Sinonasal inverted papilloma (IP) is an uncommon nasal tumor. It is known for being locally invasive and recurrent, with a high probability of malignant transformation. Accurate initial staging and close surveillance are critical in the management of the disease. METHODS AND RESULTS Fluorine-18 fluorodeoxyglucose positron emission tomography (FDG PET) was performed in 5 patients with IP. High FDG uptake (maximum standardized uptake (SUVmax) value >3.0) was observed in all patients, and 2 patients with IP associated with squamous cell carcinoma (SCC) exhibited higher SUVmax values. CONCLUSION The SUVmax value of a sinonasal tumor can warn the surgeon of the probability of an associated malignancy, even when preoperative biopsy demonstrates a purely benign papilloma.
