The Effect of Rhinoplasty Dissection Planes (Sub-SMAS, Subperichondrial, and Subperiosteal) on the Viability of Diced Cartilage Grafts in a Rabbit Model.

Background: Dorsal preservation surgeries in which the subperichondral and subperiosteal planes are used to elevate the soft tissue envelope of the nose have become increasingly widespread because they can reduce postoperative edema and promote faster healing. However, the effects of surgical dissection planes on the viability of cartilage grafts are not known.

Objective: The aim of this study was to determine, in a rabbit model, the viability of diced cartilage grafts in different rhinoplasty dissection planes (sub-superficial musculoaponeurotic system [SMAS], subperichondral, subperiosteal).

Thermal Chondroplasty Technique for Costal Cartilage Harvesting and Contouring.

Although costal cartilage autograft has versatile usage, harvesting the graft is an invasive procedure with potential risks for complications. Therefore, it is important to make every effort to minimize these risks. Moreover, sculpting costal cartilage to the desired shape is challenging and time-consuming because of the natural rigidity.

The Predictive Value of Neutrophil-to-Lymphocyte Ratio for Hodgkin's Lymphoma Diagnosis in Patients with Asymptomatic Cervical Lymphadenopathy.

In patients with asymptomatic cervical lymphadenopathy, the physician often has to choose between evaluation via follow-up or open biopsy. Follow-up evaluation may lead to a delayed diagnosis of lymphoma, while an open biopsy is associated with surgical risks and costs. This dilemma can be avoided using predictive parameters.
