Post-burn philtrum restoration

One of the consequences of face burn is upper lip deformation with philtrum injury. The philtrum's absence poses severe cosmetic defects. A literature review shows no effective developed technique which allows the surgeon to restore the upper lip and the philtrum in a single-stage procedure. The article presents a new method for burn-damaged philtrum restoration. Two scar stripes are deliberately left in place above the upper lip where the normal philtral ridges should be. The width of these two stripes (ridges) should be around 4 mm. The upper lip scars, lateral both ridges and between them, are excised forming the philtral dimple. The wound is covered with a split thickness skin graft. Two U-shaped sutures are led through the skin graft, both scar stripes and deeper through the underlying tissues between stripes. A bolster is plunged between the ridges in order to fill the dimple and is fixed by the tie-over dressing with tension. The skin transplant lying laterally to the ridges is covered with a separate tie-over dressing. The bolster is being kept in place for the duration of 7 days. As a result, the scar ridges preserve their height and the dimple keeps its depth. Good long-time follow-up results (up to 7 years) were observed in all 18 patients. In most cases the dimple can be slightly smoothed with time. The suggested method of philtrum restoration is an important component of the burned upper lip reconstruction as part of the post-burn facial resurfacing. (C) 2009 Elsevier Ltd and ISBI.
