External Tissue Expansion in head and neck reconstruction.
Journal of plastic reconstructive & aesthetic surgery : JPRAS, 2008Co-Authors: Ahmed E. Lasheen, Khaled M Saad, Mahmoud RaslanAbstract:Summary Tissue Expansion has been of great value in plastic surgery especially in head and neck reconstruction. This study used external Tissue Expansion in 40 patients for head and neck reconstruction to avoid the complications associated with internal Expansion. The study included 40 patients suffering from lesions in the head and neck, which needed excision and reconstruction. We designed external Tissue expanders of different sizes and shapes to be suitable for head and neck application. The external expander was applied to the normal skin on one or both sides of the lesion and a negative pressure (−100 to −200 mbar) was created inside it. When the area of expanded Tissue was deemed to be enough to cover the raw area after lesion excision, the Expansion process was stopped and the operation was performed. The Tissue Expansion was achieved in all cases with minimal complications in the form of blisters and red spots in three cases, which were managed by stopping the Expansion process until the blisters and spots had disappeared and then starting external Expansion again. Conclusion External Tissue Expansion technique is simple, easy, safe, associated with good results, and avoids the complications of classical Expansion in head and neck reconstruction.

External Tissue Expansion using negative pressure in upper-extremity reconstruction.
The Journal of hand surgery, 2006Co-Authors: Ahmed E. LasheenAbstract:Soft-Tissue Expansion in the upper extremities is a valuable technique with increasing indications, which means that using of Tissue Expansion in reconstruction of upper limb increases day after day. Tissue Expansion with implantable balloons is a fairly standard method in reconstructive surgery. This article describes the use of external Tissue Expansion by using negative pressure in soft-Tissue reconstruction of the upper extremities in 40 patients. Valved cups (external expanders) were applied to the skin on one or both sides of the lesion. With the subsequent application of a negative pressure source to the valves, gradual Tissue Expansion occurred inside the external expanders. When there was enough surface area of the expanded skin to cover the exposed area after lesion excision, the Expansion process was stopped and surgery was performed. The upper limit of negative pressure must not exceed −200 mbar. The complications were mild and mainly involved skin blistering. External Tissue Expansion using a negative pressure technique is simple, safe, cost effective, and associated with good results in the reconstruction of soft-Tissue injuries.

Intraoperative Tissue Expansion in rhytidectomy revisited.
Plastic and reconstructive surgery, 2003Co-Authors: G. Jackie Yee, Boris Volshteyn, Charles L. PuckettAbstract:Intraoperative Tissue Expansion is an adjunct that has been used during rhytidectomy to rejuvenate the face and neck. This technique has been thought to allow for additional skin resection and, thus, increased skin tightening during rhytidectomy. The stretch of the skin by Expansion should allow for additional skin resection before closure. Also, when the force of the underlying expander is removed, the expanded skin would recoil and the advancement of the flap should become tighter, with improved results. The technique achieved some popularity a few years ago but has received little recent attention. In this study, the authors attempted to compare face-lift results of adjunctive intraoperative Tissue Expansion during rhytidectomy with similar techniques without intraoperative Expansion. The results of 50 female patients who underwent rhytidectomy for midface rejuvenation by a single operating surgeon composed the study group. Twenty-five of the patients had undergone rhytidectomy that addressed the cheek, chin, and neck areas without Expansion (nonexpanded rhytidectomy group). The other 25 patients (expanded rhytidectomy group) had adjunctive intraoperative Tissue Expansion performed with the rhytidectomy. A Tissue expander was temporarily placed beneath the rhytidectomy flaps on each side and expanded in a standard manner before final skin resection and closure. Frontal and lateral photographs were evaluated by 54 examiners. Preoperative and postoperative photographs of the 50 patients were viewed side-byside by the examiners. The patients were presented in blind fashion and random order. The examiners graded the results of each patient on a scale of improvement from 1 to 10, with 10 being the maximum level of improvement. The scores were recorded and statistically evaluated by using the two-sample t test. Evaluation of the examiners' scores showed that the mean rating given to patients in the expanded rhytidectomy group was 5.07 (SD = 1.12). The mean rating for the nonexpanded rhytidectomy group was 5.27 (SD = 1.57). When the two groups were compared using the two-sample t test, the difference between the two was not statistically significant (p = 0.6127). Intraoperative Tissue Expansion as an adjunct to rhytidectomy did not result in improved facial rejuvenation in this patient series. The authors' impression is that the benefits of Tissue Expansion do not justify the added expense, time, and risks associated with using Tissue Expansion during rhytidectomy.
