Historical Article
[Methods of larynx phoniatory function measurement in the Poznań University Department of Ear, Throat, Nose and Larynx Diseases between 1922 and 1939].
Indirect laryngoscopy development and progress initiated in 1854 by the autolaryngoscopy of the famous singing voice teacher Manuel Garcia in ENT speciality is connected with the names of L. Tuerck and J.N. Czermak, the last one being called the father of laryngoscopy. In 1878 M. Oertel used for the first time stroboscopic light in indirect laryngoscopy. The perception of stroboscopic picture is based on the Talbot principle. ⋯ For 130 years laryngostroboscopy belongs to the basic examination methods of larynx phonatory function.

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.

Case Reports
Pneumomediastinum and emphysema in a case of a soft bronchial foreign body aspiration in a child. A case report.
Foreign body aspiration is a frequent cause of hospitalization in pediatric ENT units. Pneumomediastinum and subcutaneous emphysema are possible complications of tracheobronchoscopy with foreign body removal, but it is rare, that the foreign body causes the complications itself. The authors present a very rare case of a soft bronchial foreign body aspiration in a child with such complications.

Malignant tumors constituted 25% of all gland tumors, the most frequently in parotid gland. ⋯ Malignant tumors constituted 22% of all gland tumors. Mucoepidermoid (27%) and adenoid cyst (22%) carcinomas were the most common malignant tumor. Tumor stage T3-T4 was in 88,5% cases. Accuracy of fine-needle aspiration cytology in diagnosis of parotid tumors is 81,2%.
