Objective Summarize the clinical application and elevating the caudal end of suspension laryngoscope to deal with severe glottis exposure difficulties.Method A retrospective analysis was conducted on the clinical data of 25 patients with severe dystotic glottic exposure(Cormack-Lehane grade Ⅲ or Ⅳ)who underwent laryngoscopy support surgery from January 2021 to January 2024,then analyze the intraoperative management and outcomes.Results In all the patients,after the angle of the suspension laryngoscope was adjusted to the maximum and the glottis could not be exposed satisfactorily,the caudal end of the suspension laryngoscope stent was lifted to obtain a larger tilt angle and field of view.After the caudal end of the stent was elevated by(11.50±6.31)cm,the glottis was exposed satisfactorily in 23 cases and the operation was performed successfully;In 2 cases,the laryngeal mask airway was used in conjunction with a fibrolaryngoscope and laryngeal forceps were used to extract the lesion step by step.Pharyngeal mucosal tearing and oozing of blood occurred in 24 cases,and the bleeding stopped after electrocoagulation;one case had loose and dislodged teeth.There were no significant changes in blood pressure and heart rate of patients before and after stent lifting(P＞0.05).Conclusion For the severe difficulty of glottis exposure during suspension laryngoscopic surgery,it can be dealt with by lifting the caudal end of the stent,which is a simple and effective method that does not cause serious complications and is worth clinical application.

Objective To explore the effect of 3D printing auxiliary stent on the operation of laryngeal microsurgery instrument.Methods Auxiliary stent of suspension laryngoscope was design and 3D printed.30 standardized training residents as experimental participants were randomly divided into conventional group and auxiliary stent group(15 in each group).The pig's larynx was used as a specimen,and the vocal folds were marked with localized staining.Participants performed operation on the stained areas of the vocal folds under suspension laryngoscope(60 times of grasping in 1 h).The conventional group performed operation unaided;The auxiliary stent group performed operation with the auxiliary stent as a support.Two senior chief physicians scored the participants'stability and accuracy.Results The operational stability scale score of the conventional group and the auxiliary stent group were(5.03±4.33)and(8.99±3.42),respectively;The operation accuracy rates were 58.4%(526/900)and 78.9%(710/900),respectively.The operation accuracy rate,operation stability of the auxiliary stent group were significantly higher than those in the conventional group,and the differences were significant(P<0.01).Conclusion The auxiliary stent can significantly improve the stability and accuracy of operation,which has highly application value.

Objective:To explore of auditory-vestibular function and inner ear imaging features of patients with Meniere's disease（MD） at different clinical stages. Methods:The clinical data of 110 patients with unilateral MD who were admitted from January 2023 to March 2024 were collected, and all patients were staged according to the results of pure tone hearing threshold test, including 13 patients with stage Ⅰ, 18 cases with stage Ⅱ, 65 cases with stage Ⅲ, and 14 cases with stage Ⅳ. All patients were tested for vestibular function, including caloric tests, vestibular evoked myogenic potentials（VEMPs）, vHIT and sensory integration tests（SOT）. The sites of endolymphatic hydrops were evaluated by intravenous endotogidolinium-based MRI, twenty-seven patients completed electrocochleography. Results:①The disease course time of patients with different stages was different, and the disease course time of stage Ⅰ and Ⅱ was shorter than that of stage Ⅲ and Ⅳpatients（P<0.05）. ②No statistical differences were found in clinical data or vestibular function between normal and abnormal ECochG groups（P>0.05）. ③The results of caloric tests showed that the UW% values of stage Ⅲ（45.5±14.79） and stage Ⅳ （51.57±22.44） were higher than those of stageⅠ（31.2±14.9） and stage Ⅱ（33.5±13.31）, there were statistically significant differences between stage Ⅰ and stage Ⅱ with stage Ⅲ and Ⅳ groups（P<0.05）, the total abnormal rate of cVEMP was 62.72%, there was a statistically significant difference between stageⅠand stage Ⅲ with the stage Ⅳ group（P<0.05）, the total abnormal rate of oVEMP was 71.82%, the difference between stage Ⅰ and stage Ⅳ group was statistically significant（P<0.05）. The total score of SOT comprehensive balance gradually decreased with the increase of clinical stage, and there was a significant difference between the stage Ⅰ and Ⅳ groups（H=26.08, P<0.01）, and there was a statistically significant difference in the rate of vestibular dysfunction of SOT between the two groups（χ²=6.7, P<0.05）. ④Patients with vestibular and cochlear endolymphatic hydrops, and patients with simple cochlear or vestibular had significantly differences in disease course time, clinical stages, UW% value of caloric test, abnormal rate of cVEMP and oVEMP, total SOT balance score, the rate of vestibular abnormality（P<0.01）. Among them, when the vestibular and cochlear endolymphatic hydrops are at the same time, the clinical stage of the patient is mainly stage Ⅲand Ⅳ. Conclusion:Auditory-vestibular and inner ear gadolinium-contrasted MRI examinations in clinical practice provide a supplementary reference for judging vestibular function and the type of endolymphatic hydrops.

Objective:To explore the clinical characteristics, treatment methods, and prognosis of refractory pharyngeal ulcers. Methods:A retrospective analysis was conducted on the clinical manifestations, laryngoscopic features, laboratory tests, histopathological examinations, and treatments of 78 patients diagnosed with refractory pharyngeal ulcers. Results:There was no significant difference in the proportion of males-to-females in benign lesions, while males were significantly more prevalent in cases of malignant lesions. Seven distinct pathological types of pharyngeal ulcers were identified, with the most common being simple inflammatory ulcers（18 cases）, followed by tuberculosis（16 cases）, fungi（15 cases）, lymphoma（14 cases）, squamous cell carcinoma（10 cases）, Behcet's disease（3 cases）, and myelosarcoma（2 cases）. Conclusion:The clinical manifestations and lesions associated with refractory pharyngeal ulcers are diverse. A clear diagnosis should be established based on a systematic and comprehensive medical history, specialized examinations, and additional tests to avoid misdiagnosis and mistreatment. Laryngoscopy and histopathological examinations are essential for identifying the type of lesion and guiding appropriate treatment.

Objective: The clinical characteristics of dural arteriovenous fistula with pulsatile tinnitus were analyzed to deepen the understanding of the disease. Methods: The clinical data of five patients complained of pulsatile tinnitus and diagnosed dural arteriovenous fistula in Henan People's Hospital from May 2013 to June 2018 were retrospectively analyzed, including 3 males and 2 females, aged 27-65 years. Results: The main clinical symptoms of the five patients were continuous pulsatile tinnitus, accompanied/not accompanied by headache, memory decline, etc., with a course of three months to 20 years. They were diagnosed as dural arteriovenous fistula by digital subtraction angiography, and three cases of tinnitus disappeared and two cases of tinnitus were relieved after embolization. Conclusions The dural arteriovenous fistula is a rare and complicated disease. When the patient complain of the pulsatile tinnitus, the related etiology should be considered and managed properly.

Objective: To investigate the key issues in the diagnosis and treatment of foreign body aspiration in children with tracheobronchial variations. Methods: A retrospective study was performed for 11 pediatric patients who were treated in Department of Otorhinolaryngology and Head and Neck Surgery, Henan Province People′s Hospital after a diagnosis of foreign body aspiration with tracheobronchial variations between January 2015 and December 2017. There were 7 males and 4 females among the 11 cases of foreign body aspiration with tracheobronchial variations, ranging between 9 months and 11 years of age. Results: Among 11 cases, the types of variationswere tracheal bronchus in 9 cases, bridging bronchus in 1 case and simple tracheal stenosis in 1 case. All of the pediatric patients were under general anesthesia, and the foreign bodies were removed by bronchoscopy successfully with no significant complications. Conclusions The possibility of tracheobronchial variations should be considered in children with recurrent wheezing and poor efficacy of regular treatment before foreign body aspiration. Removal of foreign body via rigid bronchoscope under general anesthesia is a safe and effective treatment. These children are needed to combine the situation oftracheobronchial variations and the location of foreign bodies to guide the operation, and strengthened the perioperative treatment.
