Scope and Service
The Division of Head and Neck Surgery is dedicated to deliver the highest standard of care for patients with cancer of the head and neck.
The head and neck surgical team comprises of experts in the field of otorhinolaryngology, plastic and reconstructive surgery who specialize in head and neck tumor extirpation and reconstruction. The specialists in the team work together and have over the years built up a reputation of a tertiary referral center, not only for Hong Kong, but also for Asia and internationally.
Via an interdisciplinary approach, experts from across disciplines come together to provide state-of-the-art care for all types and stages of head and neck tumors, specifically tailored to address the needs of individual patient. Treatment may include surgery, radiation therapy, chemotherapy, or a combination of therapies. Comprehensive treatment plans are designed to provide the highest level of care and to optimize functional outcome.
Skull Base Tumour
Tumors in the base of skull e.g. olfactory neuroblastoma, paranasal sinus malignancy, can be resected by endoscopic approach or combined cranio-facial / cranio-nasal approach.
Recurrent Nasopharygneal Tumour
Nasopharyngectomy for local recurrence
- Robot assisted approach
- Endoscopic approach
- Maxillary swing approach
- Combined cranio-facial approach
- Extra-cranial intra-cranial bypass surgery
Neck dissection for neck recurrence

- The use of narrow band imaging in the surveillance of Head and Neck cancer
- Genetic and epigenetic alterations of head and neck cancers
- Gene polymorphism and risk of recurrent nasopharyngeal carcinomas
- Molecular cancer detection with DNA, RNA, and micro-RNA markers
- Cancer stem cells and chemoresistance
- Epstein-Barr virus activities in undifferentiated nasopharyngeal carcinomas
- Use of natural polyphenols in cancer prevention and treatment
- Epigenetic alterations in laryngeal carcinomas

The Division of Head and Neck Surgery offers opportunities for local and international fellows and students to attach and learn with the team. Globally-renowned professors are invited to give lectures from time to time. Various courses, including cadaveric and animal dissection workshops, are regularly organized. We have also been organizing Head and Neck Courses annually over the past 2 decades.
