A 27-year-old female patient suffering endolymphatic sac tumor with intralabyrinthine hemorrhage was reported. The patient had hearing loss in the left ear with continuous tinnitus, and MRI showed the soft tissue shadow of endolymphatic sac. Considering that the tumor involved semicircular canal and vestibule,endolymphatic cyst tumor resection was performed by labyrinth route. After surgery, there was no cerebrospinal fluid leakage and facial nerve function was normal. More importantly, enhanced MRI of temporal bone showed no tumor recurrence 1 year after surgery.

Patients with patulous Eustachian tubes(PET) usually suffer from annoying symptoms, such as tinnitus, autophony and aural fullness, due to the excessive opening of the Eustachian tube. There is no uniform standard of treatment, and conservative therapy combined with"Stepup"surgical intervention strategy is the main treatment. In this article, we reviewed various surgical treatments of patulous Eustachian tube in recent years, including key points of surgical operation, effectiveness, safety and complications. Full communication and evaluation are needed to establish appropriate patients' expectations preoperatively. A "Stepup" treatment strategy will be carried out, including conservative treatment, tympanic membrane surgery, Eustachian tube pharyngeal orifice constriction surgery, Eustachian tube tympanic orifice plug surgery and Eustachian tube muscle surgery, which aims to maintain normal Eustachian tube function and good middle ear ventilation.

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 analyze the clinical diagnosis, treatment ，and surgical timing of otogenic intracranial complications. Methods:The clinical data of 11 patients with intracranial complications with ear symptoms as the first manifestation in Department of Otorhinolaryngology Head and Neck Surgery, Qilu Hospital of Shandong University（Qingdao） from December 2014 to June 2022 were collected, including 8 males and 3 females, aged from 4 to 69 years. All patients had complete otoendoscopy, audiology, imaging and etiology examination, and the diagnosis and treatment plan was jointly developed through multidisciplinary consultation according to the critical degree of clinical symptoms and imaging changes. Among the 11 patients, 5 cases were treated with intracranial lesions first in neurosurgery department and middle ear lesions later in otolaryngology, 3 cases of meningitis, were treated with middle ear surgery after intracranial infection control, 1 case was treated with middle ear lesions and intracranial infection simultaneously, and 2 cases were treated with sigmoid sinus and transverse sinus thrombosis conservatively. They were followed up for 1-6 years. Descriptive statistical methods were used for analysis. Results:All the 11 patients had ear varying symptoms, including ear pain, pus discharge and hearing loss, etc, and then fever appeared, headache, disturbance of consciousness, facial paralysis and other intracranial complication. Otoendoscopy showed perforation of the relaxation of the tympanic membrane in 5 cases, major perforation of the tension in 3 cases, neoplasia in the ear canal in 1 case, bulging of the tympanic membrane in 1 case, and turbidity of the tympanic membrane in 1 case. There were 4 cases of conductive hearing loss, 4 cases of mixed hearing loss and 3 cases of total deafness. Imaging examination showed cholesteatoma of the middle ear complicated with temporal lobe brain abscess in 4 cases, cerebellar abscess in 2 cases, cholesteatoma of the middle ear complicated with intracranial infection in 3 cases, and sigmoid sinus thrombophlebitis in 2 cases. In the etiological examination, 2 cases of Streptococcus pneumoniae were cultured in the pus of brain abscess and cerebrospinal fluid, and 1 case was cultured in streptococcus vestibularis, Bacteroides uniformis and Proteus mirabilis respectively. During the follow-up, 1 patient died of cardiovascular disease 3 years after discharge, and the remaining 10 patients survived. There was no recurrence of intracranial and middle ear lesions. Sigmoid sinus and transverse sinus thrombosis were significantly improved. Conclusion:Brain abscess, intracranial infection and thrombophlebitis are the most common otogenic intracranial complications, and cholesteatoma of middle ear is the most common primary disease. Timely diagnosis, multidisciplinary collaboration, accurate grasp of the timing in the treatment of primary focal and complications have improved the cure rate of the disease.

OBJECTIVES: Chronic suppurative otitis media (CSOM) and middle ear cholesteatoma (MEC) are the 2 most common chronic middle ear diseases. In the process of diagnosis and treatment, the 2 diseases are prone to misdiagnosis and missed diagnosis due to their similar clinical manifestations. High resolution computed tomography (HRCT) can clearly display the fine anatomical structure of the temporal bone, accurately reflect the middle ear lesions and the extent of the lesions, and has advantages in the differential diagnosis of chronic middle ear diseases. This study aims to develop a deep learning model for automatic information extraction and classification diagnosis of chronic middle ear diseases based on temporal bone HRCT image data to improve the classification and diagnosis efficiency of chronic middle ear diseases in clinical practice and reduce the occurrence of missed diagnosis and misdiagnosis. METHODS: The clinical records and temporal bone HRCT imaging data for patients with chronic middle ear diseases hospitalized in the Department of Otorhinolaryngology, Xiangya Hospital from January 2018 to October 2020 were retrospectively collected. The patient's medical records were independently reviewed by 2 experienced otorhinolaryngologist and the final diagnosis was reached a consensus. A total of 499 patients (998 ears) were enrolled in this study. The 998 ears were divided into 3 groups: an MEC group (108 ears), a CSOM group (622 ears), and a normal group (268 ears). The Gaussian noise with different variances was used to amplify the samples of the dataset to offset the imbalance in the number of samples between groups. The sample size of the amplified experimental dataset was 1 806 ears. In the study, 75% (1 355) samples were randomly selected for training, 10% (180) samples for validation, and the remaining 15% (271) samples for testing and evaluating the model performance. The overall design for the model was a serial structure, and the deep learning model with 3 different functions was set up. The first model was the regional recommendation network algorithm, which searched the middle ear image from the whole HRCT image, and then cut and saved the image. The second model was image contrast convolutional neural network (CNN) based on twin network structure, which searched the images matching the key layers of HRCT images from the cut images, and constructed 3D data blocks. The third model was based on 3D-CNN operation, which was used for the final classification and diagnosis of the 3D data block construction, and gave the final prediction probability. RESULTS: The special level search network based on twin network structure showed an average AUC of 0.939 on 10 special levels. The overall accuracy of the classification network based on 3D-CNN was 96.5%, the overall recall rate was 96.4%, and the average AUC under the 3 classifications was 0.983. The recall rates of CSOM cases and MEC cases were 93.7% and 97.4%, respectively. In the subsequent comparison experiments, the average accuracy of some classical CNN was 79.3%, and the average recall rate was 87.6%. The precision rate and the recall rate of the deep learning network constructed in this study were about 17.2% and 8.8% higher than those of the common CNN. CONCLUSIONS The deep learning network model proposed in this study can automatically extract 3D data blocks containing middle ear features from the HRCT image data of patients' temporal bone, which can reduce the overall size of the data while preserve the relationship between corresponding images, and further use 3D-CNN for classification and diagnosis of CSOM and MEC. The design of this model is well fitting to the continuous characteristics of HRCT data, and the experimental results show high precision and adaptability, which is better than the current common CNN methods.

Objective: To collect the clinical cases of middle ear hairy polyp, and to summarize the imaging features. Methods: We retrospectively analyzed the clinical data of four cases middle ear hairy polyp confirmed by surgical and pathologic between January 2007 and January 2020 at the Affiliated Eye & ENT Hospital of Fudan University. There were three females, one male, with two left ears and two right ears, aged from 1 to 59 years. The CT and MRI imaging of the patients, and the corresponding clinical manifestations were analyzed. Results: Hairy polyps originated from tympanum in one case, originated from Eustachian tube in two cases, exhibiting recurrent otorrhea without evident inducement. The other case, hairy polyps originated from the Eustachian tube pharyngeal orifice and protruded into the nasopharyngeal cavity, with pharynx discomfort and aural fullness, endoscope showed offwhite polypoid mass with a little hair. All the four cases presented polypoid soft tissue masses on CT and MRI imaging, containing soft tissue wall and a large amount of adipose tissue, with soft tissue in the center of the mass which liked the core, and enhanced. MRI showed stratified arrangement of fat and soft tissue in the wall of the mass. Four cases all had surgical treatment, postoperative pathology examination presented that hair follicles, mature sebaceous glands and other skin appendages were found under squamous epithelium. A large amount of adipose tissue, part of muscle tissue, cartilage tissue, and some fibro-collagenous tissue were proliferated in the mass, accompanied by collagen degeneration. Conclusion: The middle ear hairy polyps has imaging characteristics, the polypoid soft tissue mass usually looks smooth and contains a large amount of adipose tissue, with a soft tissue in the center, and can be suggestively diagnosed by CT and MRI.
