Histopathologic findings of the orbicularis oculi in upper eyelid aging: total or minimal excision of orbicularis oculi in upper blepharoplasty.
OBJECTIVE It is well known that gradual loss of elastic fibers and skin relaxation cause the aging process, but whether changes in the orbicularis oculi muscle may contribute to the aging of the upper eyelid is not known. The aim of the present study was to use histopathologic examination to investigate whether the orbicularis oculi contributes to upper eyelid aging. METHODS Full-thickness up...
متن کاملOrbicularis 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 کاملAging of orbicularis oculi: anatomophysiologic consideration in upper blepharoplasty.
OBJECTIVE To investigate the anatomophysiologic aging-related changes in the orbicularis oculi muscle. METHODS We examined the full-thickness histologic characteristics of the upper eyelids from cadavers of 30-, 40-, 60-, and 70-year-old men and the muscle interference pattern (IP) of 68 healthy volunteers of both sexes aged 18 to 73 years. RESULTS Histologic analysis revealed that in the a...
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 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 ...
