Comparison of diced cartilage graft wrapped in surgicell and diced cartilage graft wrapped in fascia: an experimental study.

HYPOTHESIS: This study was conducted to compare diced cartilage grafts wrapped in fascia and diced cartilage grafts wrapped in surgicell with respect to their resorption. STUDY DESIGN: Experimental study. METHODS: Eight male Wistar Albino rats were used. After general anesthesia, two different subcutaneous pockets (upper and lower pocket) were prepared in the rat's abdomen. Surgicell-wrapped homograft that was taken from the ear was placed into the upper subcutaneous pocket. Fascia-wrapped homograft which was taken from the ear was placed into the lower subcutaneous pocket. All the rats were killed at the end of 2 months, and the samples were collected to be examined histopathologically. Cartilage mass, foreign body reaction, fibrosis, chronic inflammation, and vascularization were researched. RESULTS: Diced cartilage wrapped surgicell stained negative for glial fibrillary acidic protein (GFAP). Diced cartilage wrapped in fascia stained positive for GFAP. There was a significant difference between two groups with respect to fibrosis, chronic inflammation, and cartilage mass. There was no significant difference between the two groups regarding vascularization. CONCLUSIONS: This study suggests that diced cartilage graft wrapped in surgicell was absorbed, whereas diced cartilage graft wrapped in fascia was not.

Isolated maxillary sinus Ewing's sarcoma.

Extraskeletal Ewing's sarcoma is rarely found arising in the head and neck region. Only six cases of extraskeletal Ewing's sarcoma invading the nasal cavity or paranasal sinuses have been reported in the literature. The first described case of that Ewing's sarcoma located in isolated maxillary sinus extending into the orbita without involving the nose is presented. A 16-year-old woman presented with swelling in her right cheek. The nasal examination was normal. A computed tomography (CT) and magnetic resonance imaging (MRI) of the sinuses revealed a large mass in the right maxillary sinus with extension to the orbita. Under general anesthesia biopsies were taken. Based on histopathological analysis, a diagnosis of extraskeletal Ewing's sarcoma was made. The patient did not accept the surgical therapy. The patient was treated with combined chemotherapy and radiotherapy. The patient has done without evidence of recurrence or metastasis for one year.
