Otolaryngology Ward

The Department of Otolaryngology of the Second Affiliated Hospital of Dalian Medical University is a Key Clinical Discipline of Liaoning Province (development unit) and has been selected as a first-level key discipline of Dalian Municipality for 21 consecutive years. The department currently has 50 beds, 20 physicians, and 3 technicians, including 7 doctors and 13 master's degree holders; 10 chief physicians, 5 deputy chief physicians, and 3 attending physicians. It handles more than 120,000 outpatient and emergency visits annually, discharges more than 3,000 patients each year, and performs 2,500 operations. It is equipped with advanced diagnostic and surgical equipment, including the ZESS otology microscope, Storz endoscopy system, Philips sleep monitoring system, Medtronic surgical power system, Meichuang low-temperature plasma system, and electronystagmograph. Its techniques, including microscopic middle-ear surgery, endoscopic nasal and sinus surgery, and minimally invasive pharyngolaryngeal surgery under video laryngoscopy, have reached an advanced level in China.

The department comprises three subspecialties: otology, rhinology, and laryngology. Each subspecialty is staffed by 3–4 chief physicians and 1–2 attending physicians, and has developed distinctive diagnostic and treatment capabilities for pediatric snoring, hearing loss, tinnitus and vertigo, allergic rhinitis, acute and chronic rhinosinusitis, and obstructive sleep apnea-hypopnea syndrome, as well as minimally invasive surgery for malignant tumors of the pharynx and larynx.

In 2009, the department became a standardized residency training base of the Ministry of Health. In 2010, it became a doctoral training base for the second-level discipline of otolaryngology at Dalian Medical University. It is also the only institution in southern Liaoning authorized to confer doctoral degrees in otolaryngology. The department has 3 doctoral supervisors and 9 master's supervisors, and undertakes undergraduate teaching and postgraduate training at Dalian Medical University, as well as standardized residency training.

The department has undertaken 13 projects funded by the National Natural Science Foundation of China, including 1 key project of the Foundation, 12 provincial scientific research projects, and 3 municipal scientific research projects, with total funding exceeding RMB 8.2 million. Over the past five years, it has published more than 10 SCI papers and more than 20 papers in nationally recognized core journals. The department conducts in-depth cooperation with the State Key Laboratory of Structural Analysis for Industrial Equipment at Dalian University of Technology, the provincial key laboratory for digital media processing and transmission, and the Dalian Institute of Chemical Physics of the Chinese Academy of Sciences. It has produced numerous research achievements in the biomechanics of otolaryngological organs and diseases and in basic research on otolaryngological diseases, and has translated some of these achievements into applications. Its independently developed visualized curved-support laryngoscope is now used clinically; the smart anti-snoring belt linked with the snoring-care app has been successfully launched; and its nasal packing device received the second prize of the Liaoning Provincial Science and Technology Progress Award.
