Skeletal reconstruction in cleft palate patients.

Improved management techniques of secondary cleft palate deformities are steadily evolving. The year's literature under review focuses mostly on the various methods available for establishing a complete and stable dental arch. Bone from the mandibular symphysis seems to offer a more reliable source of autogenous bone than do other sites, although if the residual cleft is large, this site may not provide sufficient bone. The optimum time to graft the alveolus appears to be after the incisors have erupted, but before the canine root has fully formed and the crown broken through the mucosa. Mucoperiosteal flaps give better long-term results than do mucosal flaps. Long-term stability of the alveolar segments may be achieved with extended bridges, and the use of rigid internal fixation may offer better three dimensional stability of the maxilla following advancement and inferior repositioning. Pharyngeal flaps have a detrimental effect on stability of the maxilla after advancement, although they may have a beneficial effect on velopharyngeal function after maxillary surgery.

[Defect prosthesis following total upper jaw resection].

Using the method described, a defect prosthesis can be fastened with the help of operatively prepared retention sites and transnasal anchorage after total upper jaw resection. The technical process of manufacture is outlined and the result demonstrated in photographs.

The history of the "Le Fort I osteotomy".

The history of temporary mobilisation of the upper jaw is described. The operation was first described 130 years ago for removal of a nasopharyngeal tumour. The maxilla was split at the level now known as a Le Fort I osteotomy. A further 80 years elapsed before this operation became part of the surgical treatment of skeletal deformities of the face.

Torque measurements of the mechanical load capacity of thin bony structures of the visceral cranium.

The stability of self-tapping screws of the Luhr (1979)-mini-plate system in thin facial bones was assessed. The maximal possible torque which can be applied to the screws before they strip the thread in the bone was measured. This end point was called the penetration torque. Only the central section of the maxillary sinus wall was unsuitable for anchorage of the screw and plate. The other sections of the osseous middle and lateral parts of the face, of the glabella and of the root of the nose have sufficient strength for bony segments to be anchored using plates.
