Brief summary
Optimal scar healing is of great importance to patients, especially following surgery of the head and neck. This study evaluates the effectiveness of preoperative silicone ointment in wound healing in head and neck surgeries.
Detailed description
Following surgical procedures, the formation of hypertrophic scars and keloids affects patients' well-being, including quality of life and mental/psychological health. Scars in certain areas, including the face, neck, ears, and upper chest and back, are especially likely to develop abnormally. Due to these adverse outcomes, patients often request products and procedures that will improve the appearance of scars. Few studies have addressed preoperative measures that can improve scar healing. Surgeons often recommend that patients apply moisturizing ointments to the area of the incision prior to surgery; however, this is based on clinical consensus and is not evidence-based. Silicone products are understood to promote hydration of the skin and are considered first-line prophylactic and treatment therapy for abnormal scars (hypertrophic scars and keloids) when used after a surgery or injury. This study seeks to evaluate preoperative application of silicone ointment and its effect on surgical scar healing. The success of surgical scar healing will be determined by researcher and participant ratings on validated scar assessment scales. The secondary objective of this study is to evaluate the effect of preoperative application of silicone ointment on postoperative wound complications.
Interventions
DEVICEPreoperative silicone ointment
The silicone ointment in this study is the Biodermis Scar Aid Silicone Stick, an FDA-approved silicone ointment that is available for purchase over the counter.
OTHERPreoperative placebo ointment
The placebo ointment in this study is a generic, non-flavored lip balm that is identical in packaging and texture to the Biodermis Scar Aid Silicone Stick used in the treatment arm.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Short-term wound healing measured by the Patient and Observer Scar Assessment Scale (POSAS) | 3 months after surgery | The Patient and Observer Scar Assessment Scale (POSAS) includes two components: an observer's evaluation of a scar and a patient's evaluation of a scar. The Patient Scar Assessment Scale component asks the patient the degree to which the scar is painful or itchy, how the color, stiffness, thickness, and irregularity of the scar compare to the patient's normal skin, and the patient's overall opinion of the scar. Each question is scored on a scale of 1 (not at all painful, itchy, or different) to 10 (very much painful, itchy, or different), and the numbers are totaled to produce a final score. The Observer Scar Assessment Scale component measures vascularity, pigmentation, thickness, relief, pliability, and surface area, as well as the observer's overall opinion of the scar. Each question is scored on a scale of 1 (like normal skin) to 10 (worst scar imaginable), and the numbers are totaled to produce a final score. |
| Long-term wound healing measured by the Patient and Observer Scar Assessment Scale (POSAS) | 12 months after surgery | The Patient and Observer Scar Assessment Scale (POSAS) includes two components: an observer's evaluation of a scar and a patient's evaluation of a scar. The Patient Scar Assessment Scale component asks the patient the degree to which the scar is painful or itchy, how the color, stiffness, thickness, and irregularity of the scar compare to the patient's normal skin, and the patient's overall opinion of the scar. Each question is scored on a scale of 1 (not at all painful, itchy, or different) to 10 (very much painful, itchy, or different), and the numbers are totaled to produce a final score. The Observer Scar Assessment Scale component measures vascularity, pigmentation, thickness, relief, pliability, and surface area, as well as the observer's overall opinion of the scar. Each question is scored on a scale of 1 (like normal skin) to 10 (worst scar imaginable), and the numbers are totaled to produce a final score. |
| Short-term wound healing measured by the Scar Cosmesis Assessment and Rating (SCAR) Scale | 3 months after surgery | The Scar Cosmesis Assessment and Rating (SCAR) scale is a validated measure consisting of both observer and patient evaluations. The observer assesses scar spread, erythema, dyspigmentation, suture marks, hypertrophy or atrophy, and overall impression. The patient reports whether the scar is itchy or painful. The SCAR scale can be used to assess scars in person or photos of scars. The total possible score ranges from 0 (best possible scar) to 15 (worst possible scar). |

Secondary
| Measure | Time frame | Description |
|---|---|---|
| Length of hospital stay | 30 days after surgery | Number of days a participant stays in the hospital following their scheduled surgery |
| Discharge location | 30 days after surgery | Location (e.g. home, skilled nursing facility, etc.) to which a participant is discharged following surgery |
| Number of readmissions | 1 year after surgery | Number of times a participant is readmitted to the hospital |
| Need for follow-up | 1 year after surgery | Number of clinic or emergency department (ED) visits that are not part of the participant's routine care |
| Wound complications | 1 year after surgery | Whether the participant had unexpected complications including infection, excessive bleeding, or dehiscence |
