Use of pressure-formed splints in oral surgery.

This article illustrates the scope of use for pressure-formed splints in two frequently encountered fields of oral surgery: maxillary segmental surgery and management of fractures of the mandible through the dental arch. The use of these splints in both fields allows significant modification of generally accepted procedures.

Dental Arch↗

The use of sutures in the mouth.

The purpose of this communication is to establish a case for a more critical review of the indications for the use of sutures in oral surgery. Observations are made on the underlying principles of surgery and, where appropriate, modifications to suit some standard surgical techniques including apicectomy are suggested, which will reduce both the post-operative inconvenience for the patient and the indications for suturing. The case is supported by a retrospective review of the sutures used in a consecutive series of 149 oral surgery patients admitted to hospital for operation under general anaesthesia.

The management of fractures of the mandible.

In some countries there is a move away from the traditional use of predominantly closed or semi-closed procedures in the management of facial fractures to widespread use of aggressive surgical techniques. Observations are made on the effect that this trend may have on the trainee Oral Surgeon. An analysis of a series of 156 consecutive cases of mandibular fracture bears out the impression that simple jaw support, when there is patient co-operation, is adequate for the treatment of the majority of mandibular fractures and that when fixation is indicated, the eyelet wiring technique gives excellent results without complicating management. When open operation is indicated, intraosseous wire suture is proposed as a convenient method for first consideration. The necessity to determine accurately the pre-accident occlusion in cases of possible malocclusion is underlined and a plea is made to exercise patience in the management of fractures, particularly when the condylar neck is involved.

The management of fractures of the zygoma.

A series of cases of zygomatic fractures was studied to see if a change to a more extensive surgical intervention was justified. The surgical anatomy of the cheekbone complex was studied and certain protective features which determine the pattern of fracture were noted; treatment which takes account of these facts was suggested. Some observations are made on diplopia and enophthalmos and a plea is made for caution in accepting the concept of the "blowout" fracture.

Collapse of the condylar head of the mandible in children and subsequent ankylosis.

Five cases are reported of children who presented with limitation of jaw movement and had some degree of deformity with shortening of the mandible on the affected side. X-ray examination demonstrated changes in the head and neck of the mandibular condyle. There were varying degress of sclerosis and new bone formation in the area extending from the neck of the condyle into the sigmoid notch. The left side was affected in each case. Parallels are drawn with Perthes' disease, and although the temporo-mandibular joint is not weight-bearing, in both conditions avascular necrosis is likely to be involved. Both have similar X-ray appearances. The fragmentation of the epiphysis in the later stages causes widening and collapse of the head of the femur and the mandibular condyle.
