Synovial chondromatosis is a condition which often affects the major joints. On rare occasions, it may affect the temporomandibular joint. We report such a case, which was mistakenly diagnosed and treated as a parotid mass. We include relevant radiological and histological investigations and a brief literature review.
We report a patient with a bipartite atlas that was noted on preoperative skull radiographs for fractures of facial bones.

The patient reported in this paper presented with a painless, rapidly growing lump in the cheek. It was excised and histology showed that this was a chrondriod syringoma which is a benign tumour of the skin appendages.
A case of squamous cell carcinoma of the tongue was complicated by post operative hyponatraemia. The criteria for the syndrome of inappropriate secretion of anti diuretic hormone, [ADH] (SIADH) were met but the patient remained hyponatraemic despite adequate treatment. The patient had previously received radical external radiotherapy to the neck and was found to be profoundly hypothyroid. Correction of the hypothyroid state led to clinical and biochemical recovery. The frequency of post-irradiation hypothyroidism and the possible mechanisms of hypothyroid-induced hyponatraemia are discussed.
The application of the recently described myocutaneous flaps in 7 cases of cancrum oris defects is shown and the consistency of the blood supply in children is stressed. The surgical anatomy is mentioned and the use of the flaps in the reconstruction of defects of the cheek, angle of mouth, lips and chin is illustrated. The excellence of the muscle island flap in preventing reankylosis if interposed into new joints in the body of the mandible is emphasised, together with the advantages over the forehead and delto-pectoral flaps when used for the same purpose.
Preliminary experience using the Mini-Flap closed suction drain after maxillofacial surgery is described. The drain fulfils many of the criteria required for drainage of small wounds about the face and neck, and is associated with a low incidence of postoperative haematoma, oozing and infection.
