A novel face pad effectively prevents salivary fistulas after parotid surgery. This pressure dressing is comfortable and reduces complications, improving patient recovery and shortening hospital stays.

Area of Science:

  • Surgical innovation
  • Postoperative care
  • Otology/Head and Neck Surgery

Background:

  • Parotid surgery poses risks, including salivary fistula formation.
  • Effective postoperative pressure application is crucial for complication prevention.
  • Traditional dressings may be less effective or comfortable.

Purpose of the Study:

  • To evaluate a newly designed face pad for postoperative pressure application after parotidectomy.
  • To assess the efficacy of the face pad in preventing salivary fistula formation.
  • To determine the impact of the face pad on superficial temporal artery blood flow.

Main Methods:

  • A custom-designed face pad was applied to patients post-parotidectomy.
  • Superficial temporal artery blood flow (peak and average peak velocity) was measured using Doppler ultrasound in volunteers.

  • Outcomes (salivary fistula rates) were compared between patients using the face pad and a control group with traditional dressings.

    • Main Results:

    • The face pad did not significantly alter superficial temporal artery peak blood flow velocity at 4-5 N pressure.
    • Average peak velocity of the superficial temporal artery significantly increased with face pad use.
    • No salivary fistulas occurred in the 47 patients using the face pad, versus 11.36% in the 44 control patients (P=.023).

    Conclusions:

    • The face pad is a stable, comfortable, and effective tool for reducing postoperative complications, specifically salivary fistulas, after parotidectomy.
    • A pressure of 4-5 N with the face pad does not impede essential blood flow in the superficial temporal artery.
    • The face pad simplifies pressure dressing, potentially shortening patient hospital stays.
