Orbicularis oculi muscle in children. Histologic and histochemical characteristics.
This is the first study devoted to the histologic and histochemical characteristics of the orbicularis oculi muscle in children to the authors' knowledge. The orbicularis muscle was compared with extraocular, facial, and limb striated muscle. Light microscopy showed the orbicularis oculi muscle to be much smaller and more loosely packed than skeletal limb muscles. It further showed these muscle...
متن کاملOverriding of the preseptal orbicularis oculi muscle in Caucasian cadavers
We aimed to microscopically examine whether Caucasian eyelids demonstrate overriding of preseptal orbicularis oculi muscle (OOM) over the pretarsal OOM in both lower and upper eyelids. Full thickness sections of 13 lower eyelids and 11 upper eyelids from seven Caucasian cadavers were examined. In the lower eyelids, all 13 specimens demonstrated clear overriding of preseptal OOM over the pretars...
متن کاملThe vertical orbicularis oculi muscle turn-over procedure for the correction of paralytic ectropion of the lower eyelid
BACKGROUND Static reconstruction surgery that tightens the tension of the inferior tarsus, thereby raising the lax lower eyelid, is a common treatment for paralytic ectropion of the lower eyelid. We present one such operative procedure, in which an orbicularis oculi muscle flap was used. METHODS The surgical technique involves partial resection of the tarsus and the skin, as well as a superio...
متن کاملEffect of hyperthyroidism on the orbicularis oculi muscle in rabbits.
PURPOSE To determine the effect of hyperthyroidism on both myofiber number and myosin heavy-chain isoform composition within the palpebral orbicularis oculi muscle in rabbits. METHODS Four New Zealand White rabbits were made hyperthyroid by injection of 3,3,3'-triiodothyroinine intraperitoneally every other day for 1 month. Four rabbits were used as control animals. After 1 month the rabbits ...
متن کاملMedial pedicled orbicularis oculi flap.
Resurfacing of the medial canthal region and bony nasal dorsum is a problem frequently encountered after tumor excisions. Traditional flaps used in this region from the glabellar and frontal areas are bulky, and donor site scar may be unsightly. A medial pedicled orbicularis oculi myocutaneous flap is an alternative. A total of 12 flaps have been used to resurface the defects secondary to basal...
