background: postoperative periorbital edema and ecchymosis are common after rhinoplasty. we studied the effect of local injection of lidocaine/adrenaline immediately before osteotomy on prevention of post-operative periorbital edema and ecchymosis in rhinoplasty. m aterials and methods: thirty healthy candidates for rhinoplasty were enrolled in the self-controlled clinical trial study. lidocain...

finger prints of 68 patients with down's syndrome and 93 controls have been collected and analyzed for topological of formulation of finger tip patterns suggested by loesch (1975). the results showed that there may be great differences in the dictionary of the finger patterns of the patients and their controls. mean lunar and radial patterns showed mostly significant differences among the patie...

background in rhinoplasty, functional and cosmetic problems of the nose are corrected. these problems cause imbalance between the nasal subunit and face. throughout these deformities, there are 4 variants, so there is a need for careful preoperative evaluation either for treatment or prevention of the occurrence. according to functional and aesthetic effects of these variables in rhinoplasty, e...

background: although, different grafts are used for nasal tip plasty in cases with under projected or ill defined tip, the selection of a graft material, which provides sufficient amount of tissue with least donor site morbidity and low recipient site complication is challenging. the objectives of the present study were to examine the usefulness of cartilaginous dorsum as a proper material for ...

Characteristics of rotor blade tip clearance flow in axial compressors can significantly affect their performance and stable operation. It may also increase blade vibrations and cause detrimental noises. Therefore, this paper is contributed to investigate tip leakage flow in a low speed isolated axial compressor rotor blades row. Simulations are carried out on near-stall condition, which is val...
