background: renal cell carcinoma is the third most common urological cancer. surgical resection is still the mainstay of treatment for this tumor. here we present a new surgical approach for the management of locally advanced renal cell carcinoma. methods: we chose ten patients with extensive renal masses. the patient, under general anesthesia after preparation and draping, was placed in the su...

INTRODUCTION Squamous cell carcinoma is one of the most common malignant tumors of the skin and oral mucosa. However, squamous cell carcinoma involving near total upper and lower lip and oral commissure is rarely seen in the English literature. Simultaneous reconstruction of the upper and lower lips has been inconclusive and presents a challenge to the surgeon. We report such a case and outline...

introduction the nasolabial flap (nlf) has many advantages in oromaxillary reconstruction, but the majority of cases are reconstructions after pathologic resections. its usage in trauma surgery, especially in the management of gunshot wounds, is rarely mentioned. case presentation three cases involving gunshot injuries to the face are presented: one for reconstruction of the nasal ala, another ...

smoking has been shown to be a complicating factor in normal wound healing. both nicotine and carbon monoxide adversely affect multiple stages of the healing process. from 1991 to 1999,407 muscle flap procedures were performed on 374 patients in a single surgical unit. a retrospective review of 261 patients was completed. patients were divided into three groups: group a, no smoking history grou...

Introduction: Reconstruction of intraoral soft tissue defects is important in restoring function and esthetic. In large defects, there will be demand for regional pedicle flaps or free flaps. Hard palate separates nasal and oral cavities. Due to the small surface area between flap and remaining palate after surgical resections, optimal blood supply of the flaps for hard palate reconstructions ...

despite all modern surgical techniques, skin flap that is considered as the main method in most reconstructive surgeries puts the skin tissue at danger of necrosis and apoptosis derived from ischemia. therefore, finding a treatment for decreasing the apoptosis derived from flap ischemia will be useful in clinic. in present study, we evaluated the effect of azelaic acid 20% and finasteride on ex...

Abstract To discover the utility of pedicled latissimus dorsi kiss flap for reconstruction chest wall defect after mastectomy. This study was a systemic analysis 12 female patients with breast tumors who were treated at Affiliated Hospital Guangdong Medical University from January 2018 to December 2019. Among them, three had malignant lobular tumors, and nine locally advanced cancer. After exte...

In this study, a new aerodynamic surface concept is introduced, which powerful vortex generator (PVG). It can delay the stall point in low-wing aircraft. This leads to significant increase CLmax of an The results research show that use PVG, due its longitudinal position, does not affect center aircraft as well static stability. advantage for method compared based on LEX, moves forward and stabi...
