[The results of treatment of laryngeal cancer in 30-year material of General Hospital in Zielona Góra]. / Wyniki leczenia raka krtani w 30-letnim materiale Oddzialu Laryngologii Szpitala Wojewódzkiego w Zielonej Górze.

The authors present the material of 520 patients with cancer of the larynx operated during 1969-1998. Most of them (60%) have had III-th and IV-th degree advanced cancer. 399 (77%) patients have had the combined treatment--laryngectomy and X-ray or Co-therapy.

[Experimental laser stapedectomy. Scanning electron microscopy studies]. / Doswiadczalna stapedotomia laserowa. Badania w mikroskopie elektronowym.

The results of experimental tests performed upon 16 human stapes taken from cadavers were presented. The aim of the experiment was to define optimal parameters of laser stapedotomy. The less harmful range of argon laser energy for making the hole 0.6 mm diameter in the stape footplate was determined. There were two zones of tissue damage around the footplate's hole seen in scanning microscope. The internal area was made of carbonized tissue. The osseous tissue of the external zone had cavernous-cystic structure and lamellar stratification.
