Bilateral acinic cell carcinoma of the parotid.
A case of bilateral acinic cell carcinoma occurring synchronously in the parotid glands is reported, treatment discussed and the literature reviewed.
Intraosseous adenoid cystic carcinoma of the mandible.
Radiolucent lesions in the jaws usually are associated with pathology of odontogenic origin. An unusual case of an adenoid cystic carcinoma arising from within the mandible is described. The origin of central salivary tumours is discussed and the literature reviewed.
Malignant fibrous histiocytoma: a report of two cases arising in sites of previous irradiation.
This report illustrates two cases of malignant fibrous histiocytoma of the maxilla arising in sites which had been irradiated. The prognosis for such tumours in the jaws appears to be very poor.
Surgery of the non-ankylosed temporomandibular joint.
Apart form the sequelae of acute trauma and ankylosis, the principal conditions affecting the temporomandibular joint for which surgery may be required are condylar hyperplasia, recurrent dislocation, internal derangement and degenerative joint disease. The indications for and techniques of surgery for these conditions are reviewed, and the results of a small survey conducted in the West Midlands are presented.
Osteochondritis dissecans affecting the temporo-mandibular joint.
A case of a single loose body occurring in the temporo-mandibular joint is described. It is probable that this case represents the degenerative process of osteochondritis dissecans, a condition not previously described in this joint. The essential features of this condition are noted as a comparison to the condition of synovial chondromatosis.

Cryosurgery, and its application to oral surgery.
The biological mechanisms of tissue necrosis by controlled freezing are discussed, with particular reference to their importance in cryosurgical technique. The clinical events following cryosurgery are decribed, together with common complications. As the oral mucosa is particularly amenable to this form of treatment, it has been used on a wide variety of oral lesions. From observations based on the treatment of over 300 patients, the advantages, disadvantages, relative indications and suitable variations in technique of cryosurgery are discussed.
