Improved Upper Blepharoplasty Outcome Using an Internal Intradermal Suture Technique: A Prospective Randomized Study

OBJECTIVETo assess whether a suture technique in upper blepharoplasty may be the cause of differences in the occurrence of suture abscess formation and focal inflammation.MATERIALS AND METHODSA Level I, randomized controlled trial. The upper blepharoplasty wound was closed with a running intradermal suture. External intradermal suturing implied that this suture was started by initially passing it through the intact skin adjacent to the wound. In contrast, internal intradermal suturing meant the intradermal suture was not started in the adjacent skin but simply within the wound itself. One week and 6 weeks after surgery, the presence of suture abscesses and focal inflammation was assessed at the entrance and exit of the sutures.RESULTSAfter 1 week, 12 abscesses (40.0%) were found at the medial side of the externally sutured upper eyelids and 4 abscesses (13.3%) in the internally sutured upper eyelids (p = .02). The presence of erythema and edema after 1 week was also significantly lower in internally sutured upper eyelids (p = .02).CONCLUSIONIn this series, the method of starting the suture (internal vs external) at the medial side of an upper blepharoplasty wound was associated with a statistically significant reduction in the incidence of medial wound inflammation and suture abscess formation at a 1-week follow-up.
