Harvesting rib cartilage grafts for secondary rhinoplasty.

BACKGROUND: Reconstruction of the nasal osseocartilaginous framework is the foundation of successful secondary rhinoplasty. METHODS: Achieving this often requires large quantities of cartilage to correct both contour deformities and functional problems caused by previous procedures. Satisfactory and consistent long-term results rely on using grafts with low resorption rates and sufficient strength to offer adequate support. Auricular cartilage, irradiated cartilage, and alloplastic materials have all been used as implantable grafts with limited success. RESULTS: In the senior author's experience (J.P.G.), rib cartilage has proven to be a reliable, abundant, and relatively accessible donor with which to facilitate successful secondary rhinoplasty surgery. CONCLUSIONS: : The authors describe in detail the techniques that they have found to be integral in harvesting rib cartilage grafts for secondary rhinoplasty.

Serum cotinine concentration and wound complications in head and neck reconstruction.

BACKGROUND: The authors examined whether the preoperative serum concentrations of cotinine accurately predict the risk of complications in patients undergoing flap reconstruction of head and neck cancer defects. METHODS: Patients with incident stage III or IV squamous cell carcinoma of the head and neck undergoing resection with pedicled or free flap reconstruction were selected from an existing database of 500 patients with squamous cell carcinoma of the head and neck who participated in a prospective epidemiologic study and were reviewed retrospectively. Preoperative serum cotinine concentrations were determined using a competitive microplate immunoassay. Complications were defined as any adverse postoperative wound outcome at either the donor or recipient site. RESULTS: Eighty-nine patients underwent 101 flap reconstructions. Thirty-seven wound complications occurred in 33 patients. Forty of the 89 patients had a serum cotinine concentration greater than 10 ng/ml; twenty (50 percent) developed postoperative complications, whereas only 13 of 49 patients (27 percent) with a serum cotinine concentration of 10 ng/ml or less developed complications (p = 0.028). The relative risk of wound complications for those with a cotinine concentration greater than 10 ng/ml was approximately double that of patients with a lower cotinine concentration (relative risk, 1.9; 95 percent CI, 1.1 to 3.3). Patients with a cotinine concentration greater than 50 ng/ml had a particularly high risk (relative risk, 2.3; 95 percent CI, 1.1 to 16.7; p = 0.024). The relative risk of wound complications was not significantly associated with self-reported smoking status or history. CONCLUSION: A serum cotinine concentration greater than 10 ng/ml may predict an increased risk of wound complication in head and neck flap reconstruction and may serve as an objective, easily measured variable with which to identify patients who may benefit from an aggressive smoking cessation program before surgery.

Dorsal augmentation with autogenous rib cartilage.

Reconstruction of the nasal osseocartilaginous framework is the foundation of successful primary and secondary rhinoplasty. When adequate septal cartilage is unavailable, the rib provides the most abundant source of cartilage for graft fabrication and is the most reliable when structural support is needed. We present the senior author's (J.P.G.) experience and evolution of techniques of dorsal augmentation with autogenous rib cartilage grafts with internal K-wire stabilization in rhinoplasty.

Isolated cervical esophageal reconstruction for rare esophageal tumors.

BACKGROUND: Isolated defects in the cervical esophagus in patients who have not undergone total laryngectomy are uncommon. We report 2 cases of rare esophageal tumors requiring reconstruction of the cervical esophagus after tumor resection. METHODS AND RESULTS: The patients were a 51-year-old woman with an esophageal granular cell tumor and a 54-year-old woman with an esophageal schwannoma. Both defects were reconstructed with a radial forearm flap. A small subclinical leak developed in 1 patient and healed spontaneously within 2 weeks. At 1 year and 2 years of follow-up, both patients were consuming a normal diet and had normal voices. CONCLUSIONS: A thin and well-vascularized flap such as the radial forearm flap is essential for reconstructing an isolated cervical esophageal defect so as to maximize functional outcome.
