Oral & Maxillofacial Surgery Unit

The Oral and Maxillofacial / Oral Surgery Unit is concerned with the diagnosis and surgical treatment of oral, salivary, maxillary and bony diseases of the oral cavity and neck.  An outpatient facility is available for the investigation and diagnosis of these diseases including biopsy.  Joint clinics are held with Oral Medicine (mucosal disease), Orthodontics (facial deformity), and Restorative (Maxillofacial Oncology / Implants / Sinus lifts) as well as assessment for the Zygomatic Implant retained prosthesis.  Sedation surgical facilities are available for the surgical management of those conditions possible under seadtion – wisdom teeth, – impacted canines, – jaw cysts, – soft tissue surgery, -TMJ procedures, – implantology and bone grafting procedures, – early oral cancers.

There is a training programme in Oral Surgery and in Oral and Maxillofacial Surgery.  Close Hospital / Consultant links are maintained with the National Maxillofacial Unit St James’s Hospital and the Mater Misericordiae Hospital as well as the Dublin Paediatric Hospitals.

Patients are seen on the referral of a general dental or medical practitioner or on the request of a Specialist or Consultant.  Where a practitioner seeks an urgent referral it is advisable to telephone, explain the situation and one of the consultants / specialists will contact you.  Any urgent possible cancer case requires an urgent telephone call, with a letter / fax (01-6127296) directed to Oral Medicine / Oral and Maxillofacial Surgery

Practitioners seeking to refer patients for removal of wisdom teeth are requested to consult the UK National Institute for Clinical Excellence Guidance on Removal of Wisdom Teeth.
