Experience with the modified Meek technique.

In 1958 Meek described the so called Meek-Wall dermatome to cut postage stamp skin grafts. This method was eclipsed by the introduction of mesh skin grafts. In 1993 Kreis and colleagues reintroduced a modified Meek technique using a dermatome running on compressed air. This technique has been used in our burn unit since August 1994. The aim of this paper is to compare the modified Meek technique with the mesh graft technique. Within a period of 20 months 41 patients were grafted using the modified Meek technique. The mean TBSAB was 54.4% with 50.0% full thickness burns. All patients were excised early. The expansion ratio was 1:4 and 1:6. In 20 patients the Meek technique was used exclusively for grafting of the trunk and the extremities with the exception of face, neck and hands. In 3 patients with a mean TBSAB of 68.3% a combination of postage stamp autologous skin grafts and cultured epithelial autografts (CEA) was applied. Compared with the mesh graft technique the Meek technique showed the following advantages: 1. The Meek method provides the true expansion ratio. 2. Small graft remnants can be utilized. 3. Grafting of full thickness burns up to 70 to 75% TBSAB becomes possible with one harvest of the donor sites. 4. The reliability of graft take is equal or better. 5. Epithelialization is achieved within 3 to 4 weeks depending on the expansion ratio. 6. The combination of widely expanded postage stamp split thickness grafts and CEA provides an excellent take rate and durable wound closure within a short time and avoids the problems associated with the engraftment of CEA on fascia. The method is simple but more demanding than the mesh technique. Compared with the mesh graft technique the preparation of Meek grafts is more time consuming and requires more staff than the Mesh technique. The cost of materials is higher. In our experience complete coverage of the Meek grafts with an overlay of meshed allografts after removal of the gauze as recommended by Kreis is not necessary using the 1:4 expansion ratio. Greater expansion ratios necessitate an overlay with meshed allografts. Regarding the scar formation no significant differences were observed compared with the mesh graft technique. In conclusion the modified Meek technique is reliable and simple to perform. This technique provides a sufficient expansion ratio enabling to graft patients with burns up to 75% TBSA with only one harvest of donor sides and without the necessity of CEA. In our opinion the Meek technique is reliable and simple to perform. This technique provides a sufficient expansion ratio enabling to graft patients with burns up to 75% TBSA with only one harvest of donor sides and without the necessity of CEA. In our opinion the Meek technique is advantageous in patients with burns greater than 45% TBSAB. In smaller burns mesh grafts should be used because of lower material cost and staff requirements. Especially in extensively burned patients the Meek technique may be cost effective avoiding the need of CEA.
