Healing II: Complications

37
Complications during healing arise when tissue repair is altered by local or systemic factors. These changes involve abnormal collagen deposition, altered biomechanics, and reduced vascular supply, impairing restoration of normal structure and function.Loss of FunctionScar tissue differs significantly from the original tissue it replaces. In the skin, fibrosis lacks adnexal structures such as hair follicles, sebaceous glands, and sweat glands. Their absence reduces tactile sensitivity, impairs...

Summary
This summary is machine-generated.

Patient-specific plates (PSPs) used in virtual surgical planning (VSP) for maxillary reconstruction with fibula free flaps show a high rate of long-term complications, often requiring plate removal but maintaining reconstruction stability.

Area of Science:

  • Oral and Maxillofacial Surgery
  • Plastic and Reconstructive Surgery
  • Biomaterials Engineering

Background:

  • Virtual surgical planning (VSP) enhances maxillary defect reconstruction using fibula free flaps.
  • Long-term complication data for patient-specific plates (PSPs) in this context are limited.

Purpose of the Study:

  • To evaluate the incidence and nature of long-term complications associated with PSPs in fibula free flap reconstructions of maxillary defects.

Main Methods:

  • Retrospective review of 39 patients undergoing maxillary reconstruction with fibula free flaps and PSPs (January 2010 - July 2022).
  • Primary outcomes included plate exposure, fracture, removal, or loose screws; secondary outcomes were infection, nonunion, or flap failure.

Main Results:

  • 14 (35.8%) patients experienced plate-related complications, including plate removal (25.6%) and hardware exposure (30.8%).
  • No plate fractures occurred. No significant differences in complications were found based on patient demographics, comorbidities, or treatment factors.
  • Average time to plate removal was 2.76 years.

Conclusions:

  • VSP facilitates stable maxillary reconstruction with fibula free flaps and PSPs in most patients.
  • Long-term follow-up indicates up to 25% of patients may require plate removal, though reconstruction stability is generally maintained.
