Background:
Secondary intention healing is an alternative to consider in large tumors or tumors located in areas of limited skin mobility, such as the scalp. To promote epithelialization, we can use Dermal Regeneration Matrix (DRM) or bone wax.
Objective:
This study aimed to compare the efficacy of DRM and bone wax in secondary intention healing of cutaneous scalp tumors in elderly patients with comorbidities.
Materials And Methods:
The medical records of 18 patients with cutaneous scalp tumor healing by secondary intention from February 2022 to April 2023 were analyzed for demographic variables, tumor and surgical characteristics, time from withdrawal of material to complete epithelialization, and need for subsequent surgical intervention.
Results:
Bone wax was used in 6 patients and DRM in 12. The mean patient age was 84.3 years, and the mean tumor size was 2.7 cm. There were no significant differences in demographics or postoperative complications between the groups. The median time to complete epithelization was 84.5 (60.2-108.7) days in the bone wax group and 105.0 (91.0-126.0) days in the DRM group, with no significant differences (P = 0.15).
Conclusions:
Bone wax is a simple and economical material that can be used for secondary intention healing of scalp tumors in elderly patients with high surgical risk.

Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...
