BACKGROUND

The anatomical complexity of the inner skull base, the severity of the pathological processes which arise here require the development of modern neuro-technologies, improvement of basal access to the turkish saddle zone and also close cooperation of health care experts in related specialties.

OBJECTIVE

The purpose of the study was determination of the linear parameters and stereotopic variability of the turkish saddle in people of mature age with extreme types of skull base.

MATERIAL AND METHODS

The study was carried out on 100 adults’ turtles of adulthood 1—2 periods (aged 22—60) regardless gender. The spatial position of standard and non-standard craniometric points of the facial and brain skull was explored with the stereotopometry method. According to the size of the basilar angle, there were 3 types of skull base specified: platybasilar, mediobasilar and flexibasilar. The linear parameters of the turkish saddle were studied by craniometry.

RESULTS

The turkish saddle is located in front of the frontal and above the Frankfurt planes in all craniotypes. In the flexibasilar type of skull base, the points of the turkish saddle, as compared with the platibasilar type, are located closely to the frontal plane and higher relatively the Frankfurt plane. It was established that the turkish saddle’s longitudinal size in the platibasilar cranitype is larger than in the flexibasilar cranitype, while the transverse size of the turkish saddle has no statistically significant difference between the types.

CONCLUSION

The spatial position of the turkish saddle and its linear parameters depend on the type of skull base which should be taken into account in planning and conducting endoscopic surgeries, and also in reconstruction of skull base defect in maxillofacial surgery.
