One-stage transoral decompression and posterior fixation in rheumatoid atlanto-axial subluxation. 1990

National Hospitals for Nervous Diseases, London, England.

An operation which combined anterior transoral decompression with posterior occipitocervical fixation was used in 68 rheumatoid patients with irreducible anterior neuraxial compression at the craniocervical junction. Fibre-optic laryngoscopy with nasotracheal intubation was less hazardous than tracheostomy. The patients underwent surgery in the lateral position to allow access both to the mouth and to the back of the neck without moving the head. Specially designed instruments allowed visualisation from the front without dividing the soft palate. Posterior stabilisation was achieved by a preformed contoured loop fixed to the occiput, the atlas and the axis by sublaminar wires. The procedure allowed immediate mobilisation and had a very low morbidity in such ill patients.

UI	MeSH Term	Description	Entries
D010614	Pharynx	A funnel-shaped fibromuscular tube that conducts food to the ESOPHAGUS, and air to the LARYNX and LUNGS. It is located posterior to the NASAL CAVITY; ORAL CAVITY; and LARYNX, and extends from the SKULL BASE to the inferior border of the CRICOID CARTILAGE anteriorly and to the inferior border of the C6 vertebra posteriorly. It is divided into the NASOPHARYNX; OROPHARYNX; and HYPOPHARYNX (laryngopharynx).	Throat,Pharynxs,Throats
D011183	Postoperative Complications	Pathologic processes that affect patients after a surgical procedure. They may or may not be related to the disease for which the surgery was done, and they may or may not be direct results of the surgery.

D001172	Arthritis, Rheumatoid	A chronic systemic disease, primarily of the joints, marked by inflammatory changes in the synovial membranes and articular structures, widespread fibrinoid degeneration of the collagen fibers in mesenchymal tissues, and by atrophy and rarefaction of bony structures. Etiology is unknown, but autoimmune mechanisms have been implicated.	Rheumatoid Arthritis

D013117	Spinal Cord Compression	Acute and chronic conditions characterized by external mechanical compression of the SPINAL CORD due to extramedullary neoplasm; EPIDURAL ABSCESS; SPINAL FRACTURES; bony deformities of the vertebral bodies; and other conditions. Clinical manifestations vary with the anatomic site of the lesion and may include localized pain, weakness, sensory loss, incontinence, and impotence.
