Th e aim of this study compares to the increase in tissue temperature and the thermal histological eff ects of ultrasonic scalpel, bipolar and unipolar electrosurgery incisions in the tongue tissue of rabbits. Th is study evaluates the histopathological changes related to thermal change and the maximum temperature values in the peripheral tissue brought about by the incisions carried out by the three methods in a comparative way. To assess thermal tissue damage induced by the three instruments, maximum tissue temperatures were measured during the surgical procedure and tongue tissue samples were examined histopathologically following the surgery. Th e mean maximum temperature values of the groups were .±. Cº for the unipolar electrocautery group, whereas .±. Cº for the bipolar electrocautery group, and .±. Cº for the ultrasonic scalpel group. Th ere was a statistically signifi cant relationship between the increase in maximum temperature values and the separation among tissue layers, edema, congestion, necrosis, hemorrhage, destruction in blood vessel walls and fi brin accumulation, and between the existence of fi brin thrombus and tissue damage depth (p<.). It was concluded that the bipolar electrocautery use gives way to less temperature increase in the tissues and less thermal tissue damage in comparison to the other methods.

Objectives: This study aims to investigate the possible correlations between the heterotopic gastric mucosa (HGM) islets in the cervical esophagus and laryngopharyngeal reflux (LPR). Patients and Methods:Between May 2010 and April 2011, 45 patients (36 females, 9 males; mean age 39.8±14.1 years; range 18 to 72 years) who had reflux symptom index (RSI) >10 and reflux finding score (RFS) >7 were included. The study group consisted of 21 patients who were diagnosed with HGM islets in the cervical esophagus, while control group consisted of 24 patients without any HGM islets assessed by upper gastrointestinal system endoscopy. Esophagus manometric examination and dual-channel 24-hour pH monitoring were performed on all patients.Results: Pretreatment mean RSI and RFS were 25.6±3.5 and 15.1±3.4 in group 1, while it was found to be 21.1±4.4 and 11.9±2.6 in group 2 (p=0.001, p=0.001). A total of 29.7% of patients who underwent pH monitoring had distal reflux, whereas 43.2% of them had proximal reflux. In group 1, distal reflux was observed in 15.4% and proximal reflux was found in 54% of the patients, while distal reflux was observed in 38% and proximal reflux was found in 38% of the patients in group 2 (p=0.152; p=0.27). Fourteen patients diagnosed with HGM had antral-and seven patients had fundal-type epithelium. Conclusion:Our study results suggest that HGM islets may be considered as an etiological factor in the patients with severe LPR with isolated proximal reflux based on the 24-hour pH monitoring.

According to the authors' study on PRP, the authors found out that by using PRP wound can be healed faster in early period of postoperative. It was seen with the authors' research that on postoperative early period crusts, bleeding and postoperative complaints are lesser.
