The morbidity of bicoronal flaps in maxillofacial surgery.

Bicoronal flaps have been used in neurosurgery to gain access to the anterior cranium for over a century. A previous paper by Henderson and Jackson (1973) described the good access afforded by the flap for Le Fort II osteotomies. This paper reviews the morbidity of the procedure in 24 patients in whom bicoronal flaps were raised for access to the mid and upper facial skeleton.

An analysis of 2,067 cases of zygomatico-orbital fracture.

A ten-year review of 2,067 cases of zygomatico-orbital fractures is presented. The age and sex distribution, anatomical types of fractures, associated maxillofacial and nonmaxillofacial trauma, and causes of the injuries are described. The majority of fractures were sustained by males and resulted from trauma inflicted in altercations. The most common associated facial fractures were mandibular; the most common associated nonmaxillofacial trauma was extremity fractures. Motorcycle accidents caused the most significant amount of associated trauma, followed by motor vehicle accidents in which no seat restraint was used by the victim. Treatment, when indicated, consisted of elevation via a temporal approach followed by fixation where necessary. The fixation methods used are presented and discussed.

A cephalometric analysis of the Le Fort II osteotomy in the adult cleft patient.

A variety of procedures are available for the correction of the secondary cleft deformity. In this study of the use of the Le Fort II osteotomy, hard and soft tissue changes are documented using 40 discrete hard and soft tissue points on each lateral cephalogram. These were compared in the pre-operative, immediate post-operative and follow-up cephalograms. Some of the possible causes for relapse were identified.

Evaluation of metacarpal bone plates in the mandibular fracture.

Of 1587 mandibular fractures, 75 (4.7 per cent) were treated by open reduction with metacarpal bone plates. The plated fractures were reviewed and evaluated for failure. Seventeen plates of the 96 placed were removed (17.7 per cent). Infection was the major cause of failure (9.4 per cent). Operator error played a role in the failure of eight out of 17 plates (47.1 per cent). Various aspects were studied in order to find the significant factors present, and these are discussed.

Total surgical management of Binder's syndrome.

Binder's syndrome consists of nasomaxillary hypoplasia with a characteristic nasal deformity. Occlusion may be normal or class III. The cephalometric appearances are almost characteristic. The Le Fort II osteotomy is ideal for correcting the problem, though initial results were not entirely satisfactory because of incomplete correction of the nasal deformity. Over the past few years the periosteum of the floor and lateral walls of the pyriform cavity has been widely dissected to obtain adequate nasal advancement. The alar base, nostril sill, and nasal spine area have been selectively augmented with carved bone or cartilage grafts. Lengthening of the columella has been achieved by advancement of bilateral nostril sill flaps into the columella. Advancement of the maxilla with a previously normal occlusion may require orthodontic treatment, either preoperatively or postoperatively, to ensure normal occlusion. The authors have treated 26 patients with this condition over the last ten years.

Investigation and management of orbital trauma.

Clinical examination and conventional radiography of the orbit following recent orbital trauma often gives an incomplete picture of the damage present. In many infra-orbital blowout injuries, damage to the medial orbital wall occurs with prolapse and sometimes incarceration of orbital contents into both the maxillary and ethmoidal air sinuses. Late enophthalmos is thought to be caused by both atrophy of orbital fat and its loss into the paranasal sinuses. Hypocycloidal tomography in an antero-posterior plane is helpful in the recognition of those defects, but it does not distinguish between the presence of blood clot and soft tissue. Computerised axial tomography (C.A.T.) and ultrasonography are currently available investigative techniques which do distinguish between the presence of air, blood clot, soft tissue and bone and, in addition, there is a significant reduction in radiation dosage when compared with tomography. A comparison of these techniques and the clinical findings is described. These investigations should indicate the necessity for surgical intervention and prevent some of the late complications, such as enophthalmos.

The use of proplast in oral and maxillo-facial surgery.

The use of Proplast in the restoration of contour defects and for reconstruction of alveolar ridges is described. An evaluation of the results of treatment suggests it is a useful material for the restoration of facial contour, but that there is a significant risk of infection when the intra-oral approach is adopted.

Aneurysmal bone cyst of the zygomatic arch.

A case is described of an aneurysmal bone cyst which, because of its normal anatomical location, caused considerable difficulties in diagnosis and clinical management. The literature concerning aneurysmal bone cysts of the jaw is reviewed and the pathogenesis of this rare but interesting lesion is briefly discussed.
