Severe subcutaneous emphysema following orbital blowout fracture.
A 19-year-old man sustained a blowout fracture to the left orbital floor. Subcutaneous emphysema developed after a protracted sneezing episode. Some signs of respiratory distress ensued, and the patient was emergently intubated. He underwent surgical repair of the fracture and then had further extension of the subcutaneous emphysema. The left nasal cavity was packed and the emphysema slowly resolved. Clinically significant subcutaneous emphysema is an uncommon complication of orbital blowout fracture. Informing the patient to avoid excessive nose-blowing and to avoid occluding the nose while sneezing may prevent this complication.

Histologic comparison of autologous fat processing methods.
PURPOSE: To perform a quantitative analysis of adipocyte viability after fat processing during autologous fat transfer, comparing the processing methods of washing, centrifuging, and sedimentation. METHODS: An experimental study was conducted in which 24 fat samples were obtained after processing from 22 patients undergoing autologous fat transfer. Histologic analysis of periodic acid-Schiff-stained specimens was then performed. RESULTS: Cell counts per high-powered field of intact adipocytes and nucleated adipocytes and adipocyte cross-sectional area were significantly greater in samples processed by sedimentation, compared with those by centrifuging or washing. CONCLUSIONS: Of the various processing techniques currently used during autologous fat transfer, sedimentation appears to yield a higher proportion of viable adipocytes than does washing or centrifuging.
