Otorhinolaryngology Specialist

23 years of clinical experience
Specialty: Otorhinolaryngology
Alumni of: Capital Medical University, Beijing, China

Professional Background: Completed advanced subspecialty training at West China Hospital of Sichuan University, Beijing Friendship Hospital, Peking University Cancer Hospital, and Massachusetts Eye and Ear Infirmary, Harvard Medical School. Acquired comprehensive expertise in cutting-edge surgical techniques and theoretical frameworks in otology, rhinology, laryngology, and skull base surgery, including endoscopic resection of sinonasal and skull base tumors, cochlear implantation, facial nerve reconstruction, and thyroid ablation. Actively engaged in national academic forums such as the Annual Meeting of the Otorhinolaryngology-Head and Neck Surgery Branch of the Chinese Medical Association, where she has delivered multiple invited lectures on multidisciplinary management of obstructive sleep apnea (OSA) and precision strategies for allergic rhinitis prevention and control.

Clinical Expertise: Proficient in minimally invasive surgical techniques across key domains—otology (tympanoplasty), rhinology (endoscopic sinus surgery, septoplasty), and laryngology (laryngeal function-preserving procedures, low-temperature plasma-assisted tonsillectomy and adenoidectomy)—guided by the principles of minimal invasiveness, precision, and individualized care. Pioneered the integration of barbed-suture palatopharyngoplasty with real-time polysomnography (PSG) monitoring to optimize therapeutic outcomes in adult OSA patients; routinely performs minimally invasive interventions for pediatric OSA. Developed a stratified intervention model for allergic rhinitis combining house dust mite immunotherapy and sphenopalatine ganglion block, achieving an efficacy rate exceeding 85%. Established a comprehensive diagnostic and therapeutic protocol for tinnitus and sensorineural hearing loss, employing a sequential treatment approach for sudden deafness with a 70% efficacy rate. Skilled in managing complex cases including refractory epistaxis and tracheocutaneous fistula closure, with specialized expertise in endoscopic airway reconstruction for scar- or tumor-related airway stenosis in post-COVID-19 critical care patients.
