Intra-oral carcinoma can present in a variety of ways. Whilst carcinoma classically presents as an irregular, indurated, painless mass or ulcer, it is also recognised as being a great 'mimic' of benign lesions. A series of four cases of intra-oral squamous cell carcinoma is presented in which the initial presentation suggested a lesion of benign or dental origin. Factors which raise the index of suspicion are discussed.

A useful but underused technique of mandibular fixation is described. Its main advantages over more traditional techniques are that it is easily and rapidly applied, suitable for both children and adults, and generally well tolerated. The method can be employed where only a few teeth are present and in displaced fractures together with an intraosseous buccal plate wire. It is a method that can be recommended for use in nonmaxillofacial units and in areas where only basic equipment and facilities are available.
Temporomandibular joint pain and dysfunction is a common complaint and a frequent cause of referral to oral and maxillofacial surgeons. The importance of considering malignant disease in the differential diagnosis is illustrated by the following cases of parotid gland neoplasia which were referred as temporomandibular joint dysfunction.

Neurological damage following the sagittal split osteotomy is a commonly recognised complication. The results of 38 osteotomies in 19 patients following a minimum post-operative period of 2 years is presented. Subjective evaluation demonstrated normal sensation in 73.7% of osteotomy sides. However, objective evaluation demonstrated normal sensation in only 34.2% of sides. The remainder had a variable degree of sensory loss.
A series of 15 mandibular keratocysts is presented. Criteria and methods of treatment are outlined, in particular radical enucleation and bone packing.
