[Anesthesia in cranio-facial surgery].

Reconstructive operations on the facial skeleton and on the skull have been widely introduced in surgery. Increment of indications and augmentation of traumaticity from surgical interventions pose to anesthesiologist a set of such problems, as tracheal intubation, antinociceptive protection, prevention of hepatocerebral encephalopathy. The peculiarities of cerebral and hepatic circulation and metabolism as well as approaches in anesthesia and craniofacial surgery are discussed.

[Developmental defects of the facial the skull in some forms of craniosynostosis].

Changes in the facial skull of 74 patients with untimely synostosis of craniocerebral sutures and pathologic shape of the cerebral skull are characterized. All the patients presented with shortened base of the skull, gross deformations of the facial skull. Certain regularities in the formation of these defects were distinguished.

[An x-ray method for determining the position of the tongue in the oral cavity].

The suggested modified technique for assessing the tongue position in the oral cavity is based on teleroentgenography in the lateral projection and estimation of cephalometric parameters. Theoretical rationale is given for the use of skeletal check points in the mandibular area and cervical portion of the spine and of the mandibular and spinal reference lines. Indications for the use of this method are defined and its advantages described.

[Comparative evaluation of diagnostic preparations].

The diagnostic value of preparations is commonly characterized by sensitivity and specificity. But not all these characteristics make it possible to decide unequivocally which of the preparations to be compared is superior to the other one with respect to its diagnostic value. It is proposed that in the choice of a diagnostic preparation its capacity to provide data for exact diagnosis should be considered, i.e. the additional characteristic indicating the spread of the disease under study. As an example, the comparison of the diagnostic value of conventional methods and the polymerase chain reaction in the diagnostics of helicobacteriosis is presented. The described method for the evaluation of the diagnostic value of the preparation is well-grounded, simple and obvious.

[The evaluation of the diagnostic value of PCR test systems according to the results of state trials].

The method for the diagnostic value evaluation of preparations, based on the calculation of the accuracy of test results and taking into account the spread of the diagnosed disease (the comparison of the PCR test systems for the diagnostics of hepatitis B and ureaplasmosis) is proposed. As shown in this work, evaluations obtained with the use of this method coincide with those obtained on the basis of prognostic value, but are more convenient in use and provide additional information.

[X-ray assessment of the size of the nasopharynx].

A new method for x-ray diagnosis of nasopharyngeal size is based on the use of long-distance roentgenography in the lateral projection and of skeletal markers to estimate the cephalometric parameters. The authors draw attention to the usefulness of measuring the size of bone base, soft-tissue structures, and nasopharyngeal air column when assessing the function of the nasopharynx and throat.

[A comparison of clinical, x-ray and surgical data in posttraumatic deformities of the naso-orbital complex].

Observation and palpation could not fully determine the damage caused by trauma in posttraumatic patients. With intra-operation findings and X-ray imaging compared, the latter failed to reveal the full amount of bone destruction, except for the fractures of several parts of orbital interior walls at the level of lamina papyracea. The X-ray investigation routine comprising lateral observational view and medial zonography performed using an OP-6 device proved most effective. In cases when special devices are not available the semiaxial projection and eccentric orbital picture are most informative.

[The surgical treatment of patients with extensive defects of the soft palate].

A modified technique of velopharyngoplasty is described, involving preliminary epithelialization of the total wound surface of the musculomucous flap and the newly formed wound defect on the posterior wall of the pharynx by submerged skin transplantation. The results of treatment of 12 patients with various types of postoperative extensive defects of the soft palate demonstrate a high efficacy of the developed technique.

[X-ray changes in persons with facial skeleton deformities of the "long face" type].

The analysis of X-ray data suggested that the syndrome of "long face" could be caused by three types of changes: (1), preferential lengthening of lower jaw bone; (2), combination of lower micrognathia with increased vertical dimensions of middle facial zone; (3), prevailing anterior extension of the middle facial zone. In all the three groups the vertical dimensions of the chin region of mandible were frequently enlarged.
