An experimental study on the comparison of the effects of triester glycerol oxide on wound repair.

AIM: The aim of this study is to assess the effects of triester glycerol oxide (TGO) on cutaneous wound epithelization process. MATERIAL AND METHODS: Fifty-four male Wistar rats were divided into 2 groups of 27 rats each: control(C) and TGO (PX). The groups have been divided into three subgroups which included nine rats each regarding the wound excision on the 3rd, 7th, and 10th days, respectively. The specimens were evaluated according to histological properties and hydroxyproline levels. RESULTS: Seventh day examination showed that PX and control groups present the same score. HP levels in the control group were significantly lower compared to PX groups. CONCLUSION: TGO have positive effects on wound epithelization process by increased collagen synthesis.

A new preoperative radiological assessment in LeFort I surgery: anterior nasal spine-sphenoidal rostrum.

OBJECTIVE: The aim of this study is to assess the distance between the anterior nasal spine and the sphenoidal rostrum related to the LeFort I surgery in a Turkish population sample. MATERIAL AND METHODS: We retrospectively reviewed multidetector computerized tomography (MDCT) scans of 209 patients (134 males and 75 females). The images were obtained on a 64-MDCT scanner. The imaging parameters were 0.5 × 64 mm slice thickness, 0.5/0.3 mm increment, 120 kV, 250 mAs, 0.5 sn rotation time, 0.641 pitch, and 512 matrix. The distance between the anterior nasal spine and the sphenoidal rostrum was assessed with the Vitrea 2 software program. RESULTS: The study group consisted of 134 male (mean age 57.90 ± 5.86) and 75 female (mean age 54.84 ± 4.31) patients. The distance between the anterior nasal spine and the sphenoidal rostrum was ranging between 40.4 and 70.9 mm (average 58.3 ± 5.9) in males and 45.0 and 63.2 mm in (average 55.2 ± 4.3) females. In addition, no statistically significant differences were found between genders. CONCLUSION: The results of the current study showed that after 40 mm proceeding of the ball end nasal osteotome, the surgeons must be aware of penetrating the sphenoidal rostrum.
