Abstract

Insights

Surgery for temporal skin tumors poses risks to the facial nerve and deep margins. This study found a 26% rate of inadequate deep margin excision and a 4% risk of frontal branch facial nerve injury in temporal skin cancer operations.

Area of Science:

  • Dermatologic Surgery
  • Surgical Oncology
  • Facial Anatomy

Background:

  • Temporal cutaneous tumors present surgical challenges due to the facial nerve's frontal branches and risk of brow dysfunction.
  • Achieving deep margin clearance is difficult in the temporal region due to sensitive soft tissues.
  • This study addresses the research gap concerning clearance margins, tumor types, and nerve injuries in temporal region surgery.

Purpose of the Study:

  • To assess clearance margins, skin tumor types, and nerve injuries in the temporal region.
  • To evaluate the incidence of frontal-branch facial nerve injuries during temporal skin cancer surgery.
  • To analyze the adequacy of deep and peripheral excision margins for temporal skin malignancies.

Main Methods:

  • Retrospective analysis of 45 patients with temporal skin carcinoma biopsies.
  • Examination of deep and peripheral excision margins of skin malignancies.
  • Review of medical records for clinically evident frontal nerve injuries.

Main Results:

  • Basal cell carcinoma was the most common malignancy (75% male patients, mean age 77.8 years).
  • Inadequate deep margin excision occurred in 26% of cases.
  • Frontal branch nerve injury was observed in 2 patients (4.4%).

Conclusions:

  • Temporal skin lesion removal is challenging, with a 26% risk of inadequate deep margin excision and a 4% risk of frontal branch facial nerve injury.
  • Safe surgical removal of temporal skin lesions is crucial to preserve facial nerve branches.
  • Multidisciplinary approaches and patient counseling are vital for managing insufficiently removed tumors and improving outcomes.

Clinical Applications of Epidermal Stem Cells

Epidermal stem cells (EpiSCs) are mainly located at the basal layer of the epidermis. These cells repair minor injuries of the skin and replace dead skin cells. However, EpiSCs’ cannot heal severe wounds such as major burns or those from diabetes or hereditary disorders. In such cases, culturing the epidermal stem cells from the patient is possible and has yielded successful treatment options, such as laboratory-grown skin grafts. These grafts are synthesized using a patient’s own EpiSCs...
Burn Injuries01:22

Burn Injuries

Burn injuries occur when the skin and underlying tissues are damaged due to exposure to heat, electricity, chemicals, radiation, or friction. They can vary in severity, from minor superficial burns to severe deep burns that can be life-threatening.
The damage results in the death of skin cells, which can lead to a massive loss of fluid. Dehydration, electrolyte imbalance, and renal and circulatory failure follow, which can be fatal. Burn patients are treated with intravenous fluids to offset...
Healing II: Complications01:24

Healing II: Complications

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...
