The orbitozygomatic craniotomy was presented in resection of giant tumour of maxillary-ethmoidal region, orbital cavity and anterior cranial fossa. As a result of this approach the possibility of whole tumour resection was obtained. Also, easy closure of anterior fossa and avoidance of the facial deformation was achieved.

[The development of concept of partial surgery of the larynx due to supraglottic cancer].
It has been shown the conception of partial surgery of the larynx due to cancer primary develops in the supraglottic. The evolution of this method which is a consequence of progress in anatomical and embryological knowledge as well as technical possibilities of surgeons has been introduced. The modern methods of partial removal of larynx let resume physiological function of larynx with oncological security.

In mammals, the damage to the hair cells of the inner ear due to exposure to noise or other ototoxic agents is irreversible. In fish, reptiles and birds, however, the hair cells may regenerate, probably from the supporting cells. This regeneration process in the inner ear is being intensively examined in animals in the hope of curing the sensorineural hearing loss in human subjects in future. ⋯ The birds were exposed either to the noise at the level of 110 dB (A), 4 hours a day, for 5 consecutive days, or at the level of 125 dB (A), 8 hours a day, for 5 consecutive days. The results confirm that the regeneration starts immediately during the period of recovery from acoustic trauma, and the supporting cells are the main source for new, developing hair cells. Moreover, we found that the complete damage to hair cells is not necessary to the proliferation of supporting cells and that the intensity of proliferation of these cells depends on the level and time of exposure.

We present videolaryngoscopic findings of larynx of children with the injury after prolonged intubation. We pay attention on the mechanisms of the injury, risk factors and consequences. In our opinion videolaryngoscopy is a very valuable method of child larynx examination. We use computed acoustic analysis of voice to estimate results of phoniatric rehabilitation.
