Correction of cleft lip nose deformity with rib cartilage.

BACKGROUND: Correction of cleft lip nasal deformities (CLND) is often unsatisfactory because of problems resulting from cartilage weakness and strong soft tissue forces. Therefore, strong cartilaginous support, such as rib cartilage, is mandatory. OBJECTIVES: The authors describe placement of rib cartilage grafts to create a more symmetric and aesthetically acceptable repair of CLND with improved nasal air flow. METHODS: Two groups of patients, including those with unilateral and bilateral CLND, underwent operations with different sources of autologous cartilage. Group 1 received grafts from the septum and ear, whereas group 2 received grafts from the septum and ribs. Results were evaluated by 2 independent physicians who rated improvement between pre- and postoperative photographs. RESULTS: There were significant differences in postoperative improvement between patients who received septal/ear cartilage grafts and those who received septal/rib cartilage grafts in both unilateral and bilateral cases (P = .028 and P = .043, respectively). CONCLUSIONS: The authors' results demonstrate that rib cartilage has a positive effect on the aesthetic outcome of CLND operations and provides a strong support structure for correcting this deformity with minimal postoperative complications.

Diced ear cartilage with perichondrial attachment in rhinoplasty: a new concept.

BACKGROUND: Diced cartilage is a valuable material that has recently been added to the graft options in rhinoplasty. Shaping, fixation, and resorption are the main concerns with this material. Perichondrially attached diced conchal cartilage may be a new possibility to solve some of these problems. OBJECTIVES: The authors evaluate the outcome of perichondrially attached diced cartilage in a rabbit model and compare the results with injectable cartilage grafting. METHODS: Ear cartilage was removed from 1 auricle in each of the 16 rabbits included in this study; samples were divided in 2 pieces. After precise weighing, both segments were diced. The perichondrium was left attached to 1 of the pieces. Both segments were inserted in 2 separate pockets in the dorsum of the animal. After a 3-month period, both samples were removed and measured for growth/resorption. RESULTS: At the beginning of this study, the difference in weight between groups was statistically insignificant (P = .213), but 3 months after insertion, significant growth was observed in the perichondrial group (P = .019). CONCLUSIONS: The vascularization and significant growth in weight of the perichondrially attached diced cartilage samples are evidence of the viability of this material. The structural integrity and solid framework afforded by this option suggest that the material should be used more frequently in nasoskeletal augmentation.

Epidural anesthesia as a thromboembolic prophylaxis modality in plastic surgery.

BACKGROUND: Epidural anesthesia (EA) is known to reduce postoperative thromboembolic complications, but the mechanisms are poorly understood. Review of the literature revealed no reports about the ability of epidural anesthesia (EA) to reduce the risk of venous thromboembolism (VTE) in abdominal contouring surgery and/or liposuction. Most medical publications in this field are based on orthopedic cases. OBJECTIVES: The authors investigate the hypothesis that the differential nerve-blocking effect of bupivacaine, which spares motor function and permits leg movement during the operation, is the most important mechanism by which EA prevents thromboembolism. METHODS: From June 1992 to August 1995, 24 cases of abdominoplasty were performed under general anesthesia (Group 1). From September 1995 to December 2009, 371 cases of concurrent abdominoplasty and liposuction were performed under EA (Group 2). Eighteen cases (4.8%) from Group 2 were ultimately excluded from the study because of unsuccessful EA. All surgeries were performed by the senior author (FH). RESULTS: One thromboembolic event (pulmonary embolism [PE]) occurred in Group 1 (4%). No cases of deep vein thrombosis (DVT) or PE occurred among Group 2 patients. CONCLUSIONS: Together, differential epidural nerve blocks and purposeful intraoperative movement of lower-limb muscles represent an effective prophylactic mechanism that may prevent devastating DVT and resultant PE.
