RESUMEN
A method of surgical treatment of patients with upper retro- and micrognathia is proposed, consisting in improving the fixation of osteotomied maxillary complex. Implantation of carbonic ceramics behind the maxillary tubercles and osteosynthesis of bone fragments with titanium miniplates helps do without prolonged intermaxillary fixation and permits exercise in the early postoperative period, thus cutting down the invalidity period. Analysis of the results attained in 14 patients showed no relapses of maxillary deformation and a stable functional and esthetic effect.

The anthropometric and anatomical features of the pterygopalatine fossa were studied in 63 skulls of subjects belonging to 3 age groups, 60 roentgenograms of subjects without deformations of the facial skull were analyzed for the same purpose, and 50 patients with various deformations of the facial and cerebral skull were examined. The authors have detected a relationship between the length and width of the pterygopalatine fossa and the size of the posterior facial height, which fact should be born in mind to prevent the complications of bone reconstructive surgery in the middle zone of the facial skull.

Presents the results of experimental study of image distortions emerging in various methods of obtaining panoramic sonograms of the maxillary sinuses. Direct panoramic sonograms obtained with the OP-6 Sonarc orthopantomographer were found to give the most objective sizes of the intracavitary formations and their sites. The bottom of the orbit is detectable only on such sonograms. Inaccurate positioning of the head involve image distortions.
