ABSTRACT
BACKGROUND: To date, various types of acellular dermal matrix (ADM) have been developed for clinical use. AlloDerm is the most familiar type of ADM to most surgeons in breast reconstruction. It is prepared by freeze-drying. CG CryoDerm is the first form of ADM that requires no drying process. Therefore, theoretically, it has a higher degree of preservation of the dermal structures than AlloDerm. We conducted this study to compare the clinical course and postoperative outcomes of patients who underwent direct-to-implant breast reconstructions using AlloDerm and those who did using CG CryoDerm. METHODS: We performed a retrospective analysis of the medical records in a consecutive series of 50 patients who underwent direct-to-implant breast reconstruction using AlloDerm (n=31) or CryoDerm (n=19). We then compared the clinical course and postoperative outcomes of the two groups based on the overall incidence of complications and the duration of drainage. RESULTS: The mean follow-up period was 16 months. There were no significant differences in the overall incidence of complications (seroma, infection, skin flap necrosis, capsular contracture, and implant loss) between the two groups. Nor was there any significant difference in the duration of drainage. CONCLUSIONS: CG CryoDerm has the merits of short preparation time and easy handling during surgery. Our results indicate that CG CryoDerm might be an alternative allograft material to AlloDerm in direct-to-implant breast reconstruction.
ABSTRACT
BACKGROUND: The publication rate of presentations at medical international meetings has ranged from 11% to 78% with an average of 45%. To date, there are no studies about the final rate of publications at scientific meetings associated with plastic surgery from Korea. The present authors investigated the publication rate among the presentations at meetings associated with plastic surgery. METHODS: The titles and authors of the abstracts from oral and poster presentations were collected from the program books of the Congress of the Korean Society of Plastic and Reconstructive Surgeons (CKSPRS) for 2005 to 2007 (58th-63rd). All of the abstracts presented were searched for using PubMed, KoreaMed, KMbase, and Google Scholar. The titles, key words from the titles, and the authors' names were then entered in database programs. The parameters reviewed included the publication rate, type of presentation including running time, affiliation, subspecialty, time to publication, and publication journal. RESULTS: A total of 1,176 abstracts presented at the CKSPRS from 2005 to 2007 were evaluated. 38.7% of the abstracts, of which oral presentations accounted for 41.0% and poster presentations 34.8%, were published as full papers. The mean time to publication was 15.04 months. Among journals of publication, the Journal of the Korean Society of Plastic and Reconstructive Surgeons was most used. CONCLUSIONS: Brilliant ideas and innovative approaches are being discussed at CKSPRS. The 38.7% publication rate found from this research appeared a bit lower than the average rate of medical meetings. If these valuable presentations are not available as full papers, the research would be a waste of time and effort.
ABSTRACT
BACKGROUND: The purpose of this study was to retrospectively evaluate the patients who had undergone delayed correction of posttraumatic enophthalmos. METHODS: The medical charts of 85 patients with posttraumatic enophthalmos and who underwent surgical correction at the authors' medical center were reviewed. The outcomes were analyzed in relation to various factors such as the period of delayed correction, the causes of delayed correction, the type of initial injury, the pathologic site of the orbital wall, the operative methods, and the aesthetic and functional results. RESULTS: With regard to posttraumatic enophthalmos, good aesthetic and functional results were seen in most patients. The period from the initial injury up to the delayed correction ranged from 1 to 144 months (average, 20.9 months). The most common cause of posttraumatic enophthalmos was initial inadequate repair. A zygomatico-orbital fracture was initially the most frequent facial bone fracture. The most common defect site of the orbital wall was the inferior wall. Enophthalmos was significantly improved from a preoperative average of 3.16 mm to a postoperative average of 1.29 mm. CONCLUSIONS: Better functional results were achieved for the cases of mild to moderate enophthalmos with a single defect site of the orbital wall for the patients without associated facial bone fracture. We conclude that most cases of posttraumatic enophthalmos could be prevented through careful reconstruction during the first operation. Delayed correction of posttraumatic enophthalmos could be a possible reparative procedure if sufficient release of scar tissue, accurate repositioning of the dislocated orbital bones, and proper intraorbital grafting are performed.
