ABSTRACT
The concept of depressor orbicularis lateralis arises through anatomy of brow ptosis and innovations of its correction. This vertical muscle band is usually found running inferiorly from the lateral brow down along the lateral orbital rim, adjacent to the orbicularis oculi. The muscle segment is a powerful depressor of the brow and may lead to recurrent lateral eyebrow ptosis, if it is not addressed at the time of the facelift. In this review, the anatomical evidence, basic functions of depressor orbicularis lateralis, as well as its clinical relevance and the proper measures in handling this structure as part of brow ptosis and crow′s feet surgery will be discussed.
ABSTRACT
Objective@#To evaluate the therapeutic effect of choosing different surgical incisions in eyebrow lifting.@*Methods@#This research recruited 87 female who underwent eyebrow lifting in our hospital from January 2015 to December 2017, with the mean age of 52.4 years ranging from 25 to 71 years. According to the degree of the upper eyelid soft tissue laxity the level of eyebrow drooping and cosmetic patients personal requirements, we performed different surgical incisions respectively. Therefore, there were 39 cases upper-eyebrow incision, 31 cases under-eyebrow incision and 17 cases combined with upper and lower eyebrow incision.@*Results@#87 women who had undergone the 3 months to 4 years follow-up (average period, 6.3-month), are pleased with their eyebrow and rejuvenation after eyebrow lifting, with 90.8% (79 of 87) satisfaction, 6.9% (6 of 87) satisfaction basically and 2.3% (2 of 87) dissatisfaction. And only 2 patients had secondary surgery for unacceptable brow shape.@*Conclusions@#By choosing different eyebrow incisions and removing skin around the eyebrow, there were efficient ways to rectify the upper eyelid skin relaxation and eyebrow drooping, widen the double eyelid line as well as to improve crow′s-feet. We firmly believe that it is essential for surgeons to sufficiently get to know patients′ requirements and design a personalized treatment scheme according to the relaxation degree of the upper eyelid soft tissue and the shape of eye-brow.
ABSTRACT
Widened palpebral fissure has been regarded as one of the hallmarks of Bell's palsy. However, the palpebral fissure on the affected side may be narrower than that of the unaffected side. The narrowing of the palpebral fissure has been often thought as a sign caused by weakness of the levator palpebrae and Muller's muscles. However, weakness of the frontal muscle may cause drooping of the eyebrow, resulting in the narrowing of the palpebral fissure. We describe a patient of Bell's palsy with a narrowing of the palpebral fissure.
