Objective:
To explore an improved method of reconstructing the scalp soft tissue defect with the expanded skin soft tissue and treating and preventing the related complication.
Methods:
From October 2002 to June 2005, 32 patients (20 males and 12 females, aged 5-48 years) underwent reconstruction of the scalp soft tissue defects with the expanded scalp soft tissue in the two-stage operation. In the first stage, a tissue expander (cylindrical form, 50-250 ml) was implanted into the skin to achieve a skin soft tissue expansion. After a sufficient skin expansion (8 cm X 5 cm to 25 cm X 23 cm) was made by the routine water effusion for 6-16 weeks, a properly-designed skin flap was taken and transferred to reconstruct the scalp soft tissue defect in the second-stage of the operation. All the scalp defects were left after the resections of the scalp lesions, which ranged in size from 7 cm x 5 cm to 20 cm x 20 cm.
Results:
After operation, all the 32 patients had their scalp defects repaired and reconstructed well. The expanded skin flaps of all the 32 patients survived except 1 patient who had a necrosis of the distal epidermis of the flap, which healed after the dressings of the wound. The hair grew well and the scars were hidden with a satisfactory appearance. Four patients developed complications (necrosis of the distal flap in 1 patient, hematoma in 1, expander exposure in 1, and wound rupture in 1).
Conclusion:
Reconstruction of the scalp soft tissue defect with the skin soft tissue expansion is an ideal method.
