Objective:Ménière's disease（MD） is a common disorder of the inner ear. The fluctuating clinical symptoms and the absence of gold standards for diagnosis have posed serious problems for clinical diagnosis and treatment over the years. With the development of science and technology, artificial intelligence （AI） has been widely used in the field of medicine, and the potential of AI application to MD is demonstrated. The purpose of this review is to outline the use of AI in MD. Initially, specific instances where AI aids in differentiating MD from other causes of vertigo are presented. Furthermore, the role of AI in the evaluation of Endolymphatic Hydrops （EH）, particularly through imaging and biochemical assays, is highlighted due to its correlation with MD. Additionally, the effectiveness of AI in managing MD patients and forecasting disease progression is examined. In conclusion, the prevalent challenges hindering the clinical integration of AI in MD treatment are discussed, alongside potential strategies to surmount these barriers.

Hydropic ear disease is an otological disease caused by hydrops in the labyrinth of the inner ear membrane. According to the medical history and imaging classification system, it is mainly divided into two types: primary hydropic ear disease and secondary hydropic ear disease. The clinical manifestations vary depending on the anatomical localization of hydrops. Cochlear endolymphatic hydrops can lead to hearing loss, tinnitus, and ear fullness. Vestibular endolymphatic hydrops can cause dizziness, vertigo, nausea, vomiting, and gait instability. A number of studies on magnetic resonance imaging of hydropic ear disease have been carried out globally and relevant results have been obtained. This article reviews the research advances of magnetic resonance imaging of hydropic ear disease.

Delayed endolymphatic hydrops （DEH） is a rare disease that causes vertigo and is often misdiagnosed as other vertigo diseases. This article reports on a patient with vertigo who was easily misdiagnosed. The patient was a middle ear cholesteatoma complicated by labyrinthine fistula （LF）; however, his vertigo was episodic vertigo, which could not be explained solely by LF causing labyrinthitis. The possibility of endolymphatic hydrops was suspected, which was confirmed by inner ear magnetic resonance gadolinium imaging. This is the first reported case of middle ear cholesteatoma complicated by LF and DEH. The patient underwent surgical resection of the cholesteatoma and three semicircular canal obstructions at the same time. During two years postoperative follow-up, the patient did not experience a recurrence of vertigo. When diagnosing vertigo diseases, a careful history of vertigo is of utmost importance.

Objective:To investigate the characteristics of wideband acoustic immittance（WAI） measurements in patients with unilateral Ménière's disease（MD） and evaluate the clinical value of WAI in diagnosis of MD. Methods:WAI was performed in 30 patients with unilateral MD（30 ears for symptomatic and 30 ears for asymptomatic） and in 26 healthy individuals（52 ears）（control group）. The WAI measurements, including the frequency first appearing two peaks in energy absorbance（EA） tympanogram, resonance frequency（RF）, the peak value of absorbance（PVA）, the integral area of absorbance（IAA）, EA curve at peak pressure, were analyzed. Results:①The occurrence of two peaks in EA tympanogram in both the MD symptomatic and asymptomatic ear was observed in 27 ears（84.4%）, and 38 ears（70.4%） in the control group, with no significant difference in the frequency of first appearing in two peaks onset between the groups（all P>0.05）. ②The RF of the MD symptomatic ears was significantly lower than that of the asymptomatic ears（t=-3.544, P=0.001） and that of the control subjects（t=2.084, P=0.041）; there was no difference of RF between the MD asymptomatic ears and the control group（P>0.05）. ③The PVA were significantly lower in both MD symptomatic（t=4.240, P<0.01） and asymptomatic ears（t=4.202, P=0.001） than in controls. ④The IAA in MD symptomatic（t=3.295, P=0.001） and asymptomatic ears（t=3.193, P=0.003） was significantly lower than in the control group. ⑤Comparison of the EA curve at peak pressure of the three groups: the EAs of MD symptomatic ears were lower than those of the control group at the range of 1 059-2 911 Hz（all P<0.05）; the EAs of MD symptomatic ears were lower than those of MD asymptomatic ears within 1 000 Hz and 1 834-2 119 Hz（all P<0.05）; the EAs of MD asymptomatic ears were lower than those of the control group at the range of 515-2 748 Hz（all P<0.05）. Conclusion:Symptomatic ears in unilateral MD patients show alterations in some WAI measurements compared to asymptomatic ears and/or controls, suggesting that middle ear mechanical fuction of the affected side may be modified due to the endolymphatic hydrops. The clinical significance of WAI needs to be further explored in the context of evaluating MD.

Objective: To analyze the clinical characteristics of vestibular syncope (VS) associated with drop attacks (DA) in delayed endolymphatic hydrops (DEH). Methods: DEH cases with complete data were retrospectively analyzed, including three DEH cases with DA and VS (VS group), and six DEH cases without DA or VS (control group). The clinical profile, the results of neurotological examinations [such as pure tone audiometry, electrocochleography (EcochG), caloric test, vestibular evoked myogenic potentials (VEMP), and video head impulse test (vHIT)] and treatment outcomes were analyzed. Results: (1) In the VS group, there were three cases of ipsilateral DEH; in the control group, there were six cases of ipsilateral type. One case in each group had a history of migraine. (2) The prevalence of abnormal results in caloric test, vHIT, cervical VEMP, and ocular VEMP in the VS group was 3/3, 1/3, 2/2, and 2/2, respectively, and in the control group was 3/6, 0/3, 1/6, and 4/6, respectively. Two cases in each group underwent EcochG, and no identifiable waveform was elicited on the affected side, and-SP/AP ratio of unaffected side was less than 0.4. (3) Patients in both groups were initially treated with conservative medication. Two cases in the VS group subsequently received intratympanic injections of dexamethasone. No DA or VS occurred during a follow-up period lasting over one year. All patients achieved good control of vertigo during the follow-up period. Conclusions: VS may occur in the patients with DEH. The differential diagnosis of syncope in patients with otogenic vertiginous disease can help improve clinical diagnosis and treatment.

Low frequency sensorineural deafness is a common subtype of idiopathic sudden deafness. Certain patients suffered recurrent attacks without vertigo, much alike Meniere's disease. Few of them developed into definite Meniere's disease during long-term follow-up in many clinical studies. Although the pathophysiology of recurrent low frequency deafness is yet unknown, the desease is considered associated with early state of endolymphatic hydrops or migraine. Otologists shall be aware of its clinical course and careful explanation is necessary at time of initial informed consent.

BACKGROUND AND OBJECTIVES: Despite the extensive research for the Meniere's disease (MD), it's pathophysiology still remains uncertain and questionable among scientists. Clinical symptoms and audiometric tests form the basis for the diagnosis. Nevertheless the differential diagnosis can be extremely challenging, due to subjective and not specific results. Incorrect diagnosis is most likely and for this reason there is a great demand for objective and reliable tests. SUBJECTS AND METHODS: The presence of endolymphatic hydrops is necessary condition but non enough for the diagnosis. In this study we analyze retrospectively the summating potentials (SP)/action protentials (AP) ratio from peritympanic electrocochleography in 34 patients,divided in two groups (13 patients classified as defined MD and 21 patients classified as probable MD). The purpose was to identify the utility of the exam so to be able to achieve an early defined diagnosis. Furthermore our intention was to obtain an objective test, besides the clinical criteria currently in use for the diagnosis and the classification of the MD. RESULTS: The analysis of the SP/AP results shows high predictability for the MD (positive in six out of seven cases with a sensitivity greater than 80%). CONCLUSIONS: Our study demonstrates a satisfactory sensibility percentage in recurrent defined MD presentation (>80%). Early identification of MD can lead to an early treatment and control of the progression of the disease. Furthermore it could be a valuable instrument for the follow up and evaluation of the patients classified as probable MD in accordance with the criteria of the American Academy of Otolaryngology-Head and Neck Surgery (1995).

The Best clinical approaches for Meniere's disease starts from the proper diagnosis which is based on the clinical symptoms, including the characteristic features of vertigo and auditory symptoms. After first criteria has been made in 1972 by the American Academy of Otolaryngology-Head and Neck Surgery, it has been revised two times in 1985 and 1995. Japanese criteria have been made in 1974 and revised 2008. Most recent criteria of the Barany Society has been established in 2015. The basic notion is almost similar among these criteria, but detailed descriptions has been gradually changed in characteristics of vertigo and auditory symptoms based on the updated research data and consensus. Understanding of how the diagnostic criteria of Meniere's disease has been evolved is very important in terms of good clinical practice because they contain the development of knowledge about the disease. This article reviewed all the diagnostic criteria, and compared the differences.

Meningiomas account for 13 to 37% of all primary brain tumors, with 15% of all intracranial meningiomas arising in the posterior fossa. Patients with jugular foramen meningiomas (JFMs) may present with vague, non-specific vertiginous symptoms and sensorineural hearing loss (SNHL). Recently, the author encountered a unique case of JFM with symptoms similar to those of Ménière's disease and those of delayed endolymphatic hydrops. The patient discussed in the present case is a 17-year-old woman with a several month history of right SNHL and recurrent attacks of vertigo. The initial diagnosis of vertigo was later diagnosed as a JFM of the clear cell subtype, which is a remarkably rare pathological finding among intracranial meningioma. This study reports a case of JFM of the clear cell subtype in addition to a review of the literature.
