[A case report of primary extubation by partial cricotracheal resection for severe subglottic stenosis].

This patient suffered from severe subglottic stenosis(grade Ⅳb). During partial cricotracheal resection, we cut through the cricothyroid membrane and the cricoid arch along the line from the lower edge of the thyroid cartilage to 5 mm of the inferior thyroid cartilage corner anteromedially. This can protect the cricothyroid joint, effectively protect the recurrent laryngeal nerve, and also support the airway.

Suppurative Temporomandibular Arthritis Caused by Chronic Suppurative Otitis Media: A Case Report.

The clinical diagnosis and treatment, including information such as age, history, clinical symptoms, signs, audiology, imaging examination, mode of operation, and postoperative follow-up, of a patient with suppurative temporomandibular arthritis caused by chronic suppurative otitis media were analyzed. As conservative drug treatment and drainage surgery were ineffective, the patient was treated with microscopic open radical mastoidectomy, tympanoplasty, the plasty of the cavity of auricular concha, facial nerve decompression, coarctation of the mastoid cavity combined with otoendoscpic resection of the lower temporomandibular lesions, and standard anti-inflammatory treatment after surgery. The patient appeared to be cured at the 3-month follow-up.

Effects of Arctigenin in Proliferation, Migration, and Invasion of Nasopharyngeal Carcinoma 5-8F Cells.

Background: Nasopharyngeal carcinoma (NPC) is a malignant tumor of the nasopharynx.

Objective: Here, we aimed to understand better the molecular basis for arctigenin (ARG)'s ability to promote NPC 5- 8F cell invasion.

Methods: We tested the effects of several doses of ARG on 5-8F cells that had been cultured in vitro.

Analysis of postoperative effects of different semicircular canal surgical technique in patients with labyrinthine fistulas.

Objective: Different semicircular canal surgery techniques have been used to treat patients with labyrinthine fistulas caused by middle ear cholesteatoma. This study evaluated postoperative hearing and vestibular function after various semicircular canal surgeries.

Materials And Methods: In group 1, from January 2008 to December 2014, 29 patients with middle ear cholesteatoma complicated by labyrinthine fistulas were treated with surgery involving covering the fistulas with simple fascia.

Development of semicircular canal occlusion.

Surgical treatment of vertigo is performed with in-depth study of inner ear diseases. Achieving an effective control of vertigo symptoms while reducing damage to hearing and reducing surgical complications is the principle followed by scholars studying surgical modalities. Semicircular canal occlusion is aimed at treatment of partial peripheral vertigo disease and has attracted the attention of scholars because of the above advantages.

Pitavastatin protects against neomycin-induced ototoxicity through inhibition of endoplasmic reticulum stress.

Irreversible injury to inner ear hair cells induced by aminoglycoside antibiotics contributes to the formation of sensorineural hearing loss. Pitavastatin (PTV), a 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitor, has been reported to exert neuroprotective effects. However, its role in aminoglycoside-induced hearing loss remains unknown.

[The effect of expression of pepsin in vocal polyps on postoperative curative effect].

To investigate the effect of tissue pepsin expression of vocal polyps on the postoperative curative effect. Retrospectively analyze the data of 112 patients diagnosed with vocal cord polyps and undergone surgery from June 2019 to March 2021. The cases were divided into positive group and negative group according to the immunohistochemical pepsin expression.

[Feasibility and efficacy of a thyroid cartilage window technique for transoral CO₂ laser resection of early glottic cancer involving the anterior commissure].

To evaluate the feasibility and efficacy of a thyroid cartilage window resection（TCWR） technique for transoral CO₂ laser resection of early glottic cancer with involvement of the anterior commissure. Twenty-one patient who underwent a TCWR technique for transoral CO₂ laser resection early glottic carcinoma involving the anterior commissure, were retrospectively analyzed. Indices including margin status, perioperative comorbidities, voice outcomes, local control rate and recurrence free survival, were assessed.

[Autologous fat granule filling combined with microsuture technique for sulcus vocalis].

To explore and observe voice effect of the resection of the vocal fold sulcus, suture of the vocal fold mucosa, and fat granule packing under the support laryngoscope. A total of 25 patients with vocal fold sulcus underwent vocal fold sulcus resection under a support laryngoscope. After the vocal fold sulcus was removed, the mucosa on both sides of the vocal fold sulcus was sutured into a pouch.

Clinical Application of Stromal Vascular Fraction Gel in Unilateral Vocal Fold Paralysis.

Purpose: To investigate the therapeutic effect of the stromal vascular fraction gel (SVF gel) in unilateral vocal fold paralysis.

Methods: A retrospective study was performed on 22 patients who underwent SVF gel autotransplantation for unilateral vocal fold paralysis between June 2017 and December 2018. Fat was removed from the medial thigh under anesthesia and the SVF gel was prepared using standard techniques and injected using a suspension microlaryngoscopy.

Reliability, Validity, and Sensitivity of a Novel Smartphone-Based Eccentric Hamstring Strength Test in Professional Football Players.

Purpose: To evaluate the test-retest reliability, sensitivity, and concurrent validity of a smartphone-based method for assessing eccentric hamstring strength among male professional football players.

Methods: A total of 25 healthy male professional football players performed the Chinese University of Hong Kong (CUHK) Nordic break-point test, hamstring fatigue protocol, and isokinetic hamstring strength test. The CUHK Nordic break-point test is based on a Nordic hamstring exercise.
