Public Service
The Maxillofacial service is a regional service based at Middlemore Hospital and provides services to the wider Auckland region.
Oral and maxillofacial surgery is the surgical specialty which involves the diagnosis and treatment of diseases, injuries and defects affecting the mouth, jaws, face and neck.
Oral and maxillofacial surgeons treat impacted teeth, cancer patients requiring dental implants, jaw joint problems, salivary gland disease, dental infections, facial deformity and abnormal bite, oral cancer, other tumours and cysts of the jaws and facial trauma following accidents.
Services provided Benign tumours and cysts Benign tumours and cysts of the mouth, jaws and related structures are usually treated by surgery. Dental implantsGum tissue at the site of the implant is opened up to expose the bone. The bone is drilled and a titanium implant is inserted where the root of your tooth had been. Once the bone and gum has healed (3-6 months), the post is attached to the implant and the crown is placed over the post and cemented into place.
Dental infections Dental infections are common and usually minor. They can however, spread to the cheek, throat and neck. Management involves admission, removal of the cause, drainage and antibiotics. Sometimes admission to the intensive care ward is necessary. Facial deformity and abnormal bite Orthognathic surgery involves correcting the position of the jaws to improve facial appearance and the bite. Orthognathic surgery is often preceded by orthodontic treatment. Facial trauma Surgical management of fractures of the jaws, cheekbones, and eye-sockets is undertaken at Middlemore and Auckland City Hospitals. Obstructive sleep apnoea Obstructive Sleep Apnoea (OSA) is a condition when people stop breathing while asleep. Oral cancer Cancer of the mouth, jaws and related structures is managed through a multidisciplinary clinic and may involve surgery, radiotherapy, and chemotherapy. Salivary gland surgeryParotidectomy: an incision (cut) is made in front of the ear and runs down below the jaw line. Part or all of the parotid gland is removed.
Superficial parotidectomy: an incision is made in front of the ear and runs down beneath the ear lobe. The superficial (top) lobe of the parotid gland is removed.
Submandibular gland surgery: an incision is made just below the jaw bone and the submandibular gland removed.
Temporomandibular joint (TMJ) surgeryArthroscopic: several small incisions (cuts) are made over the joint in front of the ear. A small telescopic instrument with a tiny camera attached (arthroscope) is inserted, allowing the surgeon a view of the joint. Small instruments can be inserted into the other cuts to free up the joint by e.g. removing adhesions and scarring, or repositioning a disc.
Arthroplasty (open surgery): an incision is made in front of the ear, giving the surgeon access to reconstruct the joint by e.g. smoothing joint surfaces, repairing discs or removing diseased tissue. If a joint replacement is necessary, a second incision under the angle of the jaw may be required.
Wisdom tooth and impacted tooth extractionWisdom teeth are the third molars right at the back of your mouth. They usually appear during your late teens or early twenties. If there is not enough room in your mouth they may partially erupt through the gum or not at all. This is referred to as an impacted wisdom tooth.
Due to their location wisdom teeth can be difficult to clean and are more susceptible to decay, gum disease and recurrent infections. They can cause crowding of teeth and, on rare occasions, cysts and tumours develop around them.
Your dentist will advise if some or all of your wisdom teeth need to be removed. Wisdom teeth will usually only be removed if your dentist believes they will be a significant compromise to your oral health.
Impacted tooth extraction
Your dentist may recommend extraction if you are at significantly greater risk of infection or tooth decay. Impacted teeth may be removed by your dentist or they may refer you to an oral & maxillofacial surgeon.
An incision (cut) is made in your gum and access to the impacted tooth cleared by pushing aside gum tissue and, if necessary, removing some bone. The tooth is removed whole or in pieces and the gum stitched together over the hole.
