About this study

The combination of Botulinum toxin for crow feet (lateral part of orbicularis oculi muscle) and lower blaphaloplasty might have reduces the tension on the end of lower blaphaloplasty incision whereas the scar is more visible on patient.

The main aim of this trial is to investigate whether the injection of Botulinum toxin into the bilateral orbicularis oculi muscles could improve the appearance of the scar after lower blepharoplasty.

Read the detailed description

The main aim of this double blind randomized trial is to examine whether immediate post-operative injection of botulinum toxin into lateral part of bilateral orbicularis oculis muscles (the injection technique of crow feet) can improve scar formation for lower blepharoplasty patients.

This is a double blind randomized controlled trial primarily designed to compare the scarring after secondary cleft lip repair with immediate post-operative botulinum toxin injection into the into bilateral lateral orbicularis oculi muscles in patients with lower blepharoplasty. There will be 2 main groups in this study:-

  1. Study group (Group I): Immediately after lower blepharoplasty surgery 3 injections of 2.5U of botulinum toxin over lateral part of orbicularis oculi muscle.
  2. Control group (Group II): There will be the same amount of normal saline injection after lower blepharoplasty.

Follow-up Assessments Vancouver scar scale measures pigmentation, vascularity, pliability and scar height on the postoperative 6 month Follow Up.

Visual analogue scale They were asked to score the scars on the photographs using a standard visual analogue scale graded from 0 (worst possible scar) to 10 (best possible scar).

Photographic measurement:

A ruler will be placed just below the surgical scar. Using Photoshop CS5, the scar width can be measured.

Chi-square will be used to analyze the demographic data ( i.e. Gender) The Independent T-Student test will be used to analyze the statistical significance between the two groups.

The dosage of Botox that the investigators use for crowfeet is very tiny. And this is a common clinic practice. Systemic insult is unlikely to happen. If an allergic reaction occurred it will be treated according to the severity of allergy and Diphenhydramin PO or IV form or systemic corticosteroid will be given.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Botulinum ToxinDrug

    Also called Botulinum Toxin Type A, Botox

    A total of 7.5U per side of botulinum toxin will be injected to the lateral part of obicularis oculis muscle (3 injections of 2.5 U).

  • Normal SalineOther

    Also called Na Cl 0.9%

    The same amount (3 cc) of Normal saline will be injected to the lateral part of obicularis oculis muscle

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Visual analogue scale

    to score the scars on the photographs using a standard visual analogue scale graded from 0 (worst possible scar) to 10 (best possible scar).

    Measured: 6 months after surgery

Secondary outcomes (2)
  1. Vancouver scar scale

    Use vancouver scar scale to access the scar of blepharoplasty

    Measured: 6 months after surgery

  2. Photographic measurement

    A ruler will be placed just below the surgical scar. Using Photoshop CS5, the scar width can be measured

    Measured: 6 months after surgery
