Musculature of the Pars Marginalis of the Upper Orbicularis Oris Muscle

Journal of Craniofacial Surgery, 2007
The aim of this study is to elucidate the muscular structure of the pars marginalis of the upper orbicularis oris muscle. Full-thickness upper lips of 11 Korean adult cadavers were used. Four sagittal sections were made and stained with trichrome. Throughout the vermilion zone of the upper lip, the pars marginalis is substantially anterior to the ...

Orbicularis Oris Muscle

Annals of Plastic Surgery, 1991
The release of abnormal insertions of orbicularis oris muscle from the columella and ala base, and from their inferior attachments along the labial margin, provides muscle flaps for a double-breasted suture in cleft lip repair. Using the muscle flaps for double-breasted sutures realigns the orbicularis oris muscle fibers to achieve an anatomical and ...

EMG Activity of the Orbicularis Oris Superior, Orbicularis Oris Inferior, and Masseter Muscles of a Cleft-Palate Child

Perceptual and Motor Skills, 1986
The peak amplitude of EMG activity was measured from the orbicularis oris superior (OOS), orbicularis oris inferior (OOI), and masseter muscles of a cleft-palate child and compared to data obtained from a normal child. Both children evidenced similar levels of average peak EMG activity and variability of performance across the three muscles These data ...

Study on Distribution of Terminal Branches of the Facial Nerve in Mimetic Muscles (Orbicularis Oculi Muscle and Orbicularis Oris Muscle)

Annals of Plastic Surgery, 2014
There have been many anatomical reports to date regarding the course of the facial nerve to the mimetic muscles. However, reports are relatively scarce on the detailed distribution of the terminal branches of the facial nerve to the mimetic muscles. In this study, we performed detailed examination of the terminal facial nerve branches to the mimetic ...

Arrangement of the Orbicularis Oris Muscle in Different Types of Cleft Lips

Journal Of Craniofacial Surgery, 2000
A thorough knowledge of the anatomy of the labial region, especially the arrangement of the muscle fibers, is essential for the success of primary repair of the cleft lip. Pared lateral and medial edges from 20 unilateral incomplete cleft lips and 25 unilateral complete cleft lips were obtained during primary surgery.

EMG Activity with the JAW Fixed of Orbicularis Oris Superior, Orbicularis Oris Inferior and Masseter Muscles of Articulatory Disordered Children

Perceptual and Motor Skills, 1984
Rastatter and DeJarnette (1) noted that articulatory disordered children exhibit less than normal variance for the orbicularis oris inferior muscle when repeating a series of rapid syllable trains in free speech. There remains a need to examine motor equivalence of these children under disrupred speech conditions to test the compensatory nature of the ...

A STUDY OF THE EVOKED ELECTROMYOGRAPHY OF THE SUPERIOR ORBICULARIS ORIS MUSCLE IN MAN

Plastic and Reconstructive Surgery, 1978
A study was made of the impulse conduction speed by moving recording electrodes at 5 mm intervals, successively, after stimulating facial nerves on one side in normal subjects. The findings showed that the speed of the potentials was fast and the amplitude was large, up to a distance of 0.5 cm across the midline.

EMG Activity of Orbicularis Oris Superior, Orbicularis Oris Inferior, and Masseter Muscles of Mild and Moderate Articulatory Disordered Children

Perceptual and Motor Skills, 1987
The peak amplitude of EMG activity was measured from the orbicularis oris superior, orbicularis oris inferior, and masseter muscles for 3 mild and 3 moderately articulatory disordered and 3 normal children. The three groups showed similar levels of average peak EMG activity and variance across the three muscles, suggesting that the disordered children ...

Motor Innervation Pattern of the Orbicularis Oris Muscle in Guinea Pig

1994
Using evoked electromyography, Nishimura and Yanagihara [2] found that the orbicularis oris muscle in the vicinity of the midline was innervated by bilateral facial nerves. Figure la shows the evoked electromyograms (EMG) of the orbicularis oris muscle in a normal adult.

Mitochondrial Activity of Orbicularis Oris Muscle in Unilateral Cleft Lip Patients

Plastic and Reconstructive Surgery, 1998
To better evaluate the role of a possible mitochondrial alteration in the pathogenesis of cleft lip, we obtained and examined 38 orbicularis oris muscle specimens taken from the cleft margin of both cleft and noncleft sides of 10 unilateral cleft lip infants at the time of primary closure.
