Summary

Cervical collar incisions for thyroidectomy or parathyroidectomy migrate superiorly when patients move from upright to supine positions. This predictable migration, averaging 21 mm, is unaffected by patient factors or pathology, guiding optimal incision marking.

Area of Science:

  • Surgical technique
  • Anatomy
  • Head and neck surgery

Background:

  • Optimal cervical collar incision placement for thyroidectomy and parathyroidectomy lacks standardized descriptions.
  • A clinical impression suggests superior migration of marked incisions upon supine positioning.
  • This study aimed to validate this impression and identify influencing factors.

Purpose of the Study:

  • To investigate the superior migration of cervical collar incisions from upright to supine positions.
  • To determine if patient factors (BMI, height, weight, neck circumference) influence incision migration.
  • To assess the impact of operative details and tumor pathology on incision displacement.

Main Methods:

  • Fifty patients undergoing thyroid or parathyroid surgery were included.

  • Incisions were marked 1 finger-breadth (17 mm) above the sternal notch in the upright position.
  • Incision distance from the sternal notch was remeasured in the supine, extended neck position.

    • Main Results:

    • The cervical collar incision migrated an average of 21 mm superiorly (P=0.0001) upon supine positioning.
    • This superior migration was statistically significant.
    • The extent of migration was independent of patient factors, operation type, and pathology.

    Conclusions:

    • Superior migration of cervical collar incisions during positional changes is a validated phenomenon.
    • Inappropriate incision placement can result in undesirable scarring or prominence.
    • Marking the incision 1 fingerbreadth above the sternal notch in a neutral, upright position is recommended.
