Scope and Service

The Division is composed of experts specialized in the fields of otorhinolaryngology, plastic and reconstructive surgery and general surgery. The theme of the Division is in the management of major head and neck cancer including resection and reconstruction. The specialists in the team work together and have over the years built up a reputation of a tertiary referral centre, not only for Hong Kong, but also for Asia and internationally. For patients with certain diseases, the Division attracts patients from all over the world.

Highlights on areas of special interest are shown in the following sections:

Minimally Invasive And Robotic-assisted Head and Neck Surgery

Endoscopic and robotic-asssisted surgery minimize morbidity and enhance recovery. Commonly performed procedures include:

  • Endoscopic / robotic-assisted neck dissection
  • Endoscopic / robotic-assisted nasopharyngectomy
  • Endoscopic / robotic-assisted laryngectomy

Reconstruction with pedicled flaps or microvascular free flaps

Expertise in a comprehensive range of pedicled flaps (e.g. pectoralis major, deltopectoral) and microvascular free flaps (e.g. jejunal, anterolateral thigh, radial forearm, fibula) allow optimal reconstruction after radical resection of Head and Neck malignancy.


Surgical treatment of recurrent nasopharyngeal carcinoma

Our centre has a long history in pioneering surgical treatment of residual and recurrent nasopharyngeal carcinoma. Commonly performed procedures include:

Neck disease

  • Neck dissection
  • Brachytherapy

Nasopharyngectomy

  • Endoscopic approach
  • Robotic assisted approach
  • Maxillary swing approach

Combined cranio-facial resection of skull base tumour

We collaborate with the neurosurgeons to perform both open and minimally-invasive craniofacial / cranionasal surgeries to treat patients with benign and malignant skull base disorders. Common conditions encountered include paranasal sinus malignancy, olfactory neuroblastoma, and recurrent nasopharyngeal carcinoma.


Special challenging head and neck diseases

As a tertiary-referral centres, we regularly receive local and international referrals to review and treat some of the most challenging head and neck diseases. Examples of some of these cases include carotid body tumour, cranial nerve schwannoma, recurrent head and neck tumour, sarcoma, and parapharyngeal space tumour.


Training

The Division of Head and Neck Surgery offers opportunities for local and international fellows and students to attach and learn in 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 last 2 decades.
