Remarks on Plastic, Reconstructive and Aesthetic Surgery

Gigant Facial Neurofibroma
In August 2003, a 15 year old male, with a giant tumor located on the whole left side of his face, was admitted for treatment. The changes in appearance first began to show in the 2nd month after birth and systematic enlargement lead to an overgrowth of the soft tissues and bones of the face. As a result of the pressure excerted by the tumor, the frontal bone and the surrounding protective structures became thickened and displaced posterio-inferiorly, causing a shrinking of the anterio-inferior part of the skull. Histological analysis indicated that the tumor was of neurological origin. The patient was operated on a year later because of the continued growth of the tumor. Another year later, the enlarged and protruding maxillar bone was filed down.
A radical approach is important in such cases, not only from an aesthetic point of view, but most of all because it is the best way of counteracting any regrowth of the tumour and is the most effective means of oncological prophylaxis.

Epidemiology of Lip, Alveolar Process and Palate Clefts in the Material of Hospital and Clinic of Plastic Surgery in Polanica Zdrój
The aim of the study was to determine the incidence rate of individual types of clefts, association with other congenital defects and family incidence of the disease as well as evaluation of the condition of neonates born with cleft.
Material and methods. Retrospective studies were performed in 2500 patients with cleft lip and palate treated at the Hospital and Clinic of Plastic Surgery in the years 1979-2003. There were examined 1650 patients with cleft lip with/without palate (CL±P) and 850 patients with isolated cleft palate (CP). In the group of 1650 cleft lip and palate subjects there were 775 patients with complete unilateral cleft lip and palate (UCLP), 250 patients with complete bilateral cleft lip and palate (BCLP) and 625 patients with cleft lip (CL).
Results. 1. The incidence rate of CLP: CL: CP was approximately as 5: 3: 4. Unilateral clefts were 3 times as common as bilateral clefts and they occurred twice more often on the left side. 2. CLP occurred predominantly in males- M:F ratio = 1.8 : 1; in CL- M:F = 1.3 : 1 while reverse proportions were observed in CP patients, F:M = 1.38 : 1.3. A relationship was found between the condition of the neonate as evaluated by Apgar score and the body mass and coexistence of a specific cleft. The lowest Apgar score and the lowest birth weight was observed in neonates with BCLP, while neonates with CL had the highest values. 4. There is a proportional relationship between the severity of cleft and the incidence of the defect in first degree relatives. 5. 11% of cleft patients also develop other congenital deformities, including defect syndromes, which account for 24% of all associated defects.

The objective of the paper was to determine the impact of the value of the oil pressing pressure with the cold pressing method in a screw press on the pressing course and performance. Varied values of pressure were obtained through the use of three replaceable attachments of the pressing unit with a varied diameter of the outlet conduit (ф1=2 mm, ф2=4 mm and ф3=6 mm). The soya oil pressing process performance was determined in relation to the applied attachment and the soya cultivar. Seeds of 7 Polish non-genetically modified soya cultivars constituted research material. It was proved that both variable pressure values and the used soya cultivars have impact on the pressing performance. Based on the analysis of the obtained research results it was proved that varied technical parameters and soya cultivars influence both the process performance and the remaining parameters and pressing conditions.
