Functional characterization of orbicularis oculi and extraocular muscles
The orbicularis oculi are the sphincter muscles of the eyelids and are involved in modulating facial expression. They differ from both limb and extraocular muscles (EOMs) in their histology and biochemistry. Weakness of the orbicularis oculi muscles is a feature of neuromuscular disorders affecting the neuromuscular junction, and weakness of facial muscles and ptosis have also been described in...
متن کاملA silent period in orbicularis oculi muscles of humans.
Surface electromyographic activity was recorded bilaterally from orbicularis oculi muscles when subjects relaxed and contracted eyelid muscles. Cutaneous reflex responses were evoked during both the relaxed and contraction states. Following reflex elicitation periods of muscle silence in orbicularis oculi were observed for about 10 to 15 ms after the ipsilateral R1 response and for up to 100 ms...
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...
متن کاملMonitoring orbicularis oculi predicts good intu -
Purpose: The aim of the study was to compare visual estimation of onset of neuromuscular blockade at both the adductor pollicis (AP) and the orbicularis oculi (OO) in children and to determine if monitoring the OO could predict good intubating conditions dunng vecuronium-induced neuromuscular blockade. Methods: Thirty ASA I II children (1,5-9 yr) were studied. Anaesthesia was induced with 6-8 m...
متن کاملBlood flow and mivacurium-induced neuromuscular block at the orbicularis oculi and adductor pollicis muscles.
We have studied the pattern of blood flow and pharmacodynamic profile of mivacurium-induced block at the adductor pollicis and orbicularis oculi muscles. We studied 30 adult patients anaesthetized with fentanyl, thiopentone, nitrous oxide-isoflurane, and mivacurium 0.2 mg kg-1. Neuromuscular transmission was monitored with accelerometry (TOF Guard, Biometer, Denmark). Blood flow was measured at...
