Eyelid bags and blepharochalasis are the result of relaxation of lid structures like the skin, the orbicularis oculi, and mainly the orbital septum. Therefore, this aged appearance cannot be improved sufficiently with only a skin and orbicularis oculi resection. To improve this appearance, we use a very effective method of tucking of the orbital septum with infraeyebrow excision of the skin and...

Bilateral cleft lip repairs can result in various secondary deformities. One more commonly seen deformity, the whistle deformity, is characterized by a reduced or absent tubercle, orbicularis muscle diastasis, and abnormalities of the philtrum with notched appearance of cupid's bow. Various techniques have been described to address these problems. One common procedure is the lip-switch flap ori...

the cutaneous approach, whether it is for blepharoplasty, orbital surgery, or eyelid rotation, relates to the orbicularis septal complex. Hematoma, inflammation, and scarring in this middle lamellar plane can result in eyelid retraction or volume deflation. Lower eyelid entropion surgeries accomplish their anatomic goal by creating a scar between the lower eyelid retractors and the anterior tar...

PURPOSE To clarify anatomically the facial nerve branches in the eyelids and periorbit. METHODS The facial nerve branches of the left periorbits from 31 Japanese cadavers were dissected under a surgical microscope. RESULTS The temporal, zygomatic, and deep buccal branches assembled posterior to the orbicularis oculi from its temporal or inferior side, and formed a dense plexus. The superfic...

The structure and function of the proximal hip joint capsule and the zona orbicularis are poorly understood. We hypothesized that the zona orbicularis is an important contributor to hip stability in distraction. In seven cadaveric hip specimens from seven male donors we distracted the femur from the acetabulum in a direction parallel to the femoral shaft with the hip in the neutral position. Ei...

The EMG activity of the orbicularis oris (upper and lower), and of the mentalis muscles was verified during several movements of the lips, in 18 children ageing from 8 to 12 years, divided into three groups: one with normal occlusion, and two with class II division 1, with atypical swallowing and/or incompetent lips and who had received no orthodontic treatment. In blowing through a straw the m...

BACKGROUND The exact anatomical cause of the tear trough remains undefined. This study was performed to identify the anatomical basis for the tear trough deformity. METHODS Forty-eight cadaveric hemifaces were dissected. With the skin over the midcheek intact, the tear trough area was approached through the preseptal space above and prezygomatic space below. The origins of the palpebral and o...

The early and late components of the orbicularis oculi reflex were absent bilaterally in three patients who fulfilled the clinical and electroencephalographic criteria of brain death. A response to peripheral facial nerve stimulation was obtained in all. These preliminary observations suggest that the study of the orbicularis oculi reflex is a simple, objective, bedside neurophysiological test ...
