Department of Neurosurgery I
I. Department Overview
Department of Neurosurgery I of the Second Affiliated Hospital of Hainan Medical University originated from the Neurosurgery Treatment Team of the former Third Department of Surgery at the original Hainan Provincial Nongken Hospital, founded in 1956. It evolved through the establishment of professional neurosurgery groups by Professor Chen Shouhua and Professor Zhou Guoze. In 2008, the hospital introduced Professor Mo Yehe as the Head of Neurosurgery and established an independent specialty. Through the hard work and relentless efforts of the neurosurgery team, the scale of the discipline has continuously expanded, medical conditions have progressively improved, and technical capabilities have been steadily enhanced. To meet the needs of disciplinary development, Department of Neurosurgery I and Department of Neurosurgery II were established in 2016 based on the original neurosurgery department. Department of Neurosurgery I has a total of 81 beds, including a Neurological Intensive Care Unit (NICU), general neurosurgery wards, and special needs wards. The medical and nursing team consists of 57 members, including 17 doctors and 40 nurses. Among them, there are 7 senior titles, 3 PhD holders, 1 PhD candidate, and 10 master's degree holders.

After years of development and expansion, it has become a specialized discipline engaged in the diagnosis and treatment of neurosurgical diseases with a certain scale, strong technical capabilities, and comprehensive modern facilities and equipment. It is also a key discipline integrating neurosurgical clinical practice, teaching, and research. The department's scale and level of diagnosis and treatment rank among the top in Hainan Province. Department of Neurosurgery II currently has 39 beds and a medical and nursing team of 26 people, including 8 doctors and 18 nurses. Among them, there are 3 senior titles, 1 PhD holder, 4 master's degree holders, and 1 master's supervisor. It is an academic team with high quality, high education, and a combination of senior, middle-aged, and young members. The department has a strong cultural atmosphere and a reasonable talent echelon. The team members are energetic, collaborative, reform-minded, and innovative, having pioneered several new services and technologies in and outside the province.
The Department of Neurosurgery II admits approximately 800 patients annually, handles about 1800 outpatient and emergency visits, and performs around 300 surgeries per year. The department possesses advanced diagnostic and treatment equipment. Furthermore, benefiting from the hospital's "One-Click Start" and "Green Channel" mechanisms, the intermediate links from emergency to surgery are significantly shortened, buying time for timely surgery for neurocritical emergencies like cerebral hemorrhage and brain trauma. In addition to the advantages in treating cerebral hemorrhage and craniocerebral trauma, microsurgical minimally invasive neurosurgery has become a characteristic, routinely performing microscope and neuroendoscope-assisted surgeries for common neurosurgical diseases such as brain tumors, spinal tumors, and cerebral hemorrhage.
To further streamline diagnosis and treatment channels, Neurosurgery II collaborates closely with the Emergency Department, Anesthesiology, Operating Room, Intensive Care Unit, Rehabilitation Department, Acupuncture Department, and Hyperbaric Oxygen Department. Adhering to standardized and personalized diagnosis and treatment concepts, and through interdisciplinary collaboration, it strives to provide every patient with cerebral hemorrhage or brain trauma a series of standardized, scientific, advanced comprehensive treatment plans and first-class medical technology—from emergency admission to surgical treatment, and from perioperative intensive care to postoperative rehabilitation—enabling patients to achieve favorable outcomes.
All medical staff of Department of Neurosurgery II will continue to strive, guided by the principle of "first-class technology, first-class equipment, first-class service," and utilize their strong comprehensive strength to provide patients with leading-level, comprehensive medical services.

Specialty Diagnosis and Treatment Projects
(1) Individualized minimally invasive microsurgical treatment for various common intracranial tumors, including: gliomas, meningiomas, schwannomas, pituitary adenomas, hemangioblastomas, metastases, etc. Through individualized assessment and precise localization, the goal of surgical treatment is achieved via minimally invasive microsurgical techniques.
(2) Treatment of all types of severe craniocerebral trauma, including: cerebral contusion and laceration, acute or chronic subdural hematoma, epidural hematoma, skull fracture, etc. Leveraging the advantages of neurosurgery and advanced treatment concepts, it involves comprehensive management, integrated monitoring, dynamic quantification of disease progression, and timely, accurate development of treatment plans to prevent complications. Simultaneously, under the hospital's "One-Click Start" and "Green Channel" mechanisms, a rapid diagnosis and treatment process from emergency to admission to surgery is realized, greatly improving the救治成功率 (rescue success rate) for critically ill patients.
(3) Individualized minimally invasive microsurgical treatment for cerebrovascular diseases, including: cerebral aneurysms, vascular malformations, cavernous malformations, cerebral hemorrhage, etc. Through individualized assessment, the most appropriate surgical method is selected, including the sole or combined application of microscopy, endoscopy, interventional techniques, and other means to improve diagnostic and therapeutic efficacy.
(4) Treatment of pediatric neurosurgical diseases, including various brain tumors, vascular diseases, hydrocephalus, etc.
(5) Minimally invasive microsurgical treatment for spinal diseases, including intramedullary tumors, intradural extramedullary tumors, extradural tumors, etc.
(6) Minimally invasive treatment for various functional diseases: For refractory trigeminal neuralgia, hemifacial spasm, glossopharyngeal neuralgia and other functional diseases, minimally invasive techniques are used to achieve complete decompression, relieve pain, and preserve normal vascular and nerve function.
Specialty Technologies
(1) Microsurgical treatment of gliomas. Preoperative imaging reconstruction and tumor localization via navigation or ultrasound, intraoperative electrophysiological monitoring throughout to assess neurological function, fluorescence imaging for clear tumor visualization, and meticulous tumor resection under the microscope. Multiple technical approaches are employed to strive for total tumor resection while preserving neurological function.
(2) Individualized treatment for hypertensive intracerebral hemorrhage: Based on the patient's specific condition, individualized surgical approaches are adopted, such as ultra-early minimally invasive surgery, stereotactic navigation surgery, neuroendoscopic surgery, transsylvian microsurgery, standard large decompressive craniectomy, etc., to improve patient prognosis and quality of life. Among these, neuroendoscopic minimally invasive surgery utilizes the neuroendoscope, combining minimally invasive techniques with visualization through precise optics, camera, and display technology to achieve close-range, high-definition, magnified views. Combining neuroendoscopy with 3D imaging software, neuronavigation, intraoperative ultrasound, and other technologies allows the neuroendoscope to fully leverage its advantages of accurate positioning, minimal trauma, and good efficacy. During neuroendoscopic surgery for hypertensive hemorrhage, the endoscope can be placed into the hematoma cavity, providing a clear field of view and full exposure, avoiding hematoma residue. Surgical steps include: preoperative localization, small bone window craniotomy, placement of the access channel, connection of the neuroendoscope, and hematoma evacuation.
(3) Microsurgical techniques for spinal tumors. Preoperative precise localization, intraoperative use of microscope and minimally invasive channels, combined with techniques like hemilaminectomy, and precise tumor resection under neurophysiological monitoring to accelerate patient postoperative recovery and protect neurological function.
