Table 18.9
Anaesthetic considerations during temporomandibular joint replacement

All patients have severely restricted mouth opening and a fibreoptic intubation is the airway management technique of choice

They may be elderly or have conditions such as rheumatoid arthritis, so medical comorbidities are common32

A nasal tracheal tube is necessary

A throat pack is mandatory but may be difficult to insert as mouth opening is limited

Use a viscous ointment to protect the eye; avoid tapes on the side of the surgery as the surgeon may want to see the eye

Surgery is prolonged

The surgeon may request moderate hypotension

There is a risk of sudden, severe bleeding owing to the proximity of the carotid artery to the ankylosed joint

Invasive arterial monitoring is advisable

Mouth opening may be improved after surgery, but the joint is delicate and vigorous mouth opening or mandibular manipulation should be avoided

Postoperative high dependency care is advisable for the first 24 hours

This is a painful procedure; a PCA is required postoperatively
