OBJECTIVE The mixed orbicularis oculi muscle lacks an intramuscular proprioceptive system such as muscle spindles, to induce reflex contraction of its slow-twitch fibers. We evaluated whether the mechanoreceptors in Müller's muscle function as extrinsic mechanoreceptors to induce reflex contraction of the slow-twitch fibers of the orbicularis oculi in addition to those of the levator and fronta...
To evaluate the basic technique of Ptosis probe R and the impact of ptosis repair by silicone rod frontalis sling on the Asian eyelid. A retrospective interventional study including 30 patients (49 eyelids) who underwent silicone rod frontalis suspension by the same surgeon between 2005 and 2008. Cosmetic outcomes , marginal reflex distance (MRD), chin-up head posture and recurrence rate were e...
INTRODUCTION We describe the results of 15 patients suffering from essential blepharospasm with apraxia of eyelid opening who underwent frontalis suspension surgery. MATERIAL AND METHODS Patients with apraxia of eyelid opening and unresponsive to botulinum toxin injections were studied. Bilateral frontalis suspension surgery was performed (sling operation) using polytetrafluoroethylene (Gore-...
PURPOSE Cosmetic and functional outcomes of frontalis suspension surgery using autologous fascia lata (FL) or silicone rods (SRs) in pediatric congenital ptosis. DESIGN Retrospective case series. STUDY SUBJECTS Patients with congenital ptosis, aged 18 years or younger, during the period under study (2005-2011) at the Singapore National Eye Centre. METHODS Review of case records for functi...
AIMS The aim of the study was to evaluate the results of the frontalis sling operation using silicone rod for the correction of ptosis in chronic progressive external ophthalmoplegia patients. METHODS Chronic progressive external ophthalmoplegia patients who received the frontalis sling operation using silicone rods from 1999 to 2006 were included in this study. The medical records were retro...
BACKGROUND Micrurus snake bites can cause death by muscle paralysis and respiratory arrest, few hours after envenomation. The specific treatment for coral snake envenomation is the intravenous application of heterologous antivenom and, in Brazil, it is produced by horse immunization with a mixture of M. corallinus and M. frontalis venoms, snakes that inhabit the South and Southeastern regions o...
The genetic structure of present-day populations has been highly affected by glacial periods and physical oceanographic forcing, particularly with respect to species distributions and population gene-flow patterns. We assessed the current genetic composition of the Jasus frontalis population in the southeastern Pacific Islands off the coast of Chile to evaluate their connectivity modulated by c...
Facial mimicry is the tendency to imitate the emotional facial expressions of others. Increasing evidence suggests that the perception of dynamic displays leads to enhanced facial mimicry, especially for happiness and anger. However, little is known about the impact of dynamic stimuli on facial mimicry for fear and disgust. To investigate this issue, facial EMG responses were recorded in the co...
Coral snakes (Micrurus spp.) are the main representatives of the Elapidae in South America. However, bites by these snakes are uncommon. We retrospectively reviewed the data from 11 individuals bitten by coral snakes over a 20-year period; four were confirmed (snake brought for identification) and seven were highly suspected (neuromuscular manifestations) cases of elapid envenoming. The cases w...
