RESUMO
BACKGROUND: The aim in tip surgery is to provide rotation, derotation, projection and deprojection. In this study, we aimed to show the effects of modified low septal strip septoplasty, septal extension graft, TIG technique and additional maneuvers on tip shape in dorsal preservation rhinoplasty (DPR) and to discuss our clinical results. PATIENTS AND METHODS: One hundred eighty-nine patients who underwent DPR with modified low septal strip septoplasty between November 2021 and August 2023 were included in the study. Demographic data, complications, revision surgeries and follow-up periods of the patients were analyzed retrospectively. RESULTS: The mean age of the patients is 29.58±9.04 (17-65). The mean follow-up period was 14, 50±2,98 months. Complications were observed in 1.1% of the patients (n=2/189). Revision surgery was performed in all these patients. Residual hump in 2 were observed and dorsum rasping was performed under local anesthesia. No tip revision was performed on any patient. CONCLUSIONS: A strong tip fixation is achieved with the modified low septal septoplasty technique described in this publication, and when combined with septal extension graft, tongue in groove technique and other suture techniques, an effective and permanent tip plasty can be performed in DPR.

RESUMO
BACKGROUND: Fat grafts are widely used in plastic, aesthetic and reconstructive surgery. Their unpredictable resorption is their main disadvantage. A review of the literature shows that there is a lack of research on the effect of mobile and immobile regions on fat graft survival in fat graft applications. OBJECTIVE: Our aim was to investigate the relationship of fat graft survival with mobile and immobile region in a new experimental model. METHODS: Twenty-four male Wistar albino rats were randomly divided into two groups (n=12). Fat grafts were harvested from the right inguinal region of the rat. In Group 1, the fat graft was placed in the subcutaneous pouch formed in the scalp region of the rat. In Group 2, fat grafts were placed in the pouch formed in the posterior cervical region of the rat. At the end of 6 weeks, the weights and histopathology of the fat grafts were evaluated. Histopathological examinations were performed in a blinded fashion. RESULTS: The weights of the fat grafts were found to be higher in Group 1. At the same time, histopathological examinations showed that vascular density was higher in Group 1. There was no statistically significant difference in other histopathological examinations. CONCLUSION: The mobile and immobile areas may have different effects on the survival of transplanted fat grafts. Sliding movement between muscle and skin in the mobile zone puts stress on the fat graft. In our study, the mobile site was shown to have a negative effect on the vascularity of the fat graft. It was observed that the vascular density was higher in the fat graft placed in the immobilised area. Further studies on the increase in vascularity can be carried out using the new experimental model we have created.
