Reconstruction after resection of sphenoid wing meningiomas.

Objective: To review our experience of reconstructing the lateral and superior orbital walls after resection of sphenoid wing meningiomas. We will review the presentation and complications, examine the aesthetic results postoperatively, and compare preoperative and postoperative computed tomographic scans. To our knowledge, a comparative analysis of preoperative defect and postoperative reconstruction has not been performed.

Tracheal reconstruction using tissue-engineered cartilage.

Objectives: To determine whether rabbit cartilage can be tissue engineered using a polyglycolic acid (PGA) construct composed of PGA mesh, autologous chondrocytes, and alginate covalently linked with the cell adhesion sequence arginine-glycine-aspartic acid (RGD), and to investigate the feasibility of reconstructing tracheal defects using the PGA construct in conjunction with a bioabsorbable intratracheal stent.

Methods: Nineteen New Zealand White rabbits were used. Nine rabbits underwent subcutaneous implantation of 3 different PGA construct combinations: (1) PGA, autologous chondrocytes, and RGD-modified alginate; (2) PGA, autologous chondrocytes, and unmodified alginate; and (3) PGA and RGD-modified alginate.

Management of chyle fistula utilizing thoracoscopic ligation of the thoracic duct.

Objectives: To document the treatment of refractory chyle leaks using thoracoscopic thoracic duct ligation and provide systematic guidelines to manage chyle leaks.

Methods: The medical records of 2 patients with chyle leaks are reviewed, followed by a review of the literature on chyle leaks and their thoracoscopic management.

Conclusions: Initial treatment of chyle fistula is aimed at conservative medical management.
