Muscle-nerve-muscle neurotization of the orbicularis oris muscle
Journal of Cranio-Maxillofacial Surgery, 2001A denervated half of the orbicularis oris muscle is not reinnervated spontaneously by axon sprouting from the intact contralateral side. The borderline between the facial nerve territories seems to act as a barrier. The muscle-nerve-muscle technique was advocated as a technique to reneurotize a denervated half of the orbicularis oris muscle in cases of

Adaptation in the function of the superior orbicularis oris muscle
Experimental Neurology, 1982Abstract Electromyographic analysis of the upper lip region of the rhesus monkey demonstrated that nasal obstruction could induce long-term changes in the discharge of certain fibers of the superior orbicularis oris muscle. Normal animals were compared with 14 monkeys which had their noses blocked by nasal plugs.

Differentiated Reconstruction of the Orbicularis Oris Muscle in Unilateral Labioplasty
Journal of Cranio-Maxillo-Facial Surgery, 1989Repair of the cleft lip aims to restore the normal anatomy. The most important step in treatment of unilateral deformities is the differential re-arrangement of muscle components to correct the insertion and reorientate the direction of their fibres. The three different components of the orbicularis oris muscle must be repaired independently, to permit

Anatomy of the orbicularis oris muscle in cleft lip
British Journal of Plastic Surgery, 1989The anatomy of the orbicularis oris muscle was studied using histological sections of 18 operative specimens of unilateral cleft lip (14 incomplete and 4 complete). In incomplete clefts the intrinsic part of the orbicularis, located in the vermilion, is simply interrupted without distortion.

Are There Other Muscle Fibers on the Orbicularis Oris Muscle in the Upper Lip?
Plastic & Reconstructive Surgery, 2022Background: The elevator muscles of the upper lip are the levator labii superioris alaeque nasi, levator labii superioris, and zygomaticus minor muscles, which function by means of their insertions into the skin of the upper lip.

Orbicularis Oris Muscle Injury in Brass Players
The Laryngoscope, 1996AbstractThe embouchure of the brass player is critical to tone production and largely depends on the integrity of the orbicularis oris muscle. Injury to this muscle can cripple the professional musician by causing fatigue, pain, and tonal deterioration. Ten brass players presented with muscular defects in the orbicularis oris muscle.

Relationship between EMG features and force in orbicularis oris muscle
Technology and Health Care, 2023BACKGROUND: Lip incompetence resulting from mouth breathing is a common clinical manifestation, while there are no definite indicators of amplitude and intensity of muscle functional training in clinical practice, which leads to unsatisfactory training results. OBJECTIVE: The aim was to quantify the relationship between electromyography (EMG) and force

Turns amplitude analysis of the orbicularis oculi and oris muscles
Clinical Neurophysiology, 2005The aim of the study was to determine whether 'clouds' from turns amplitude analysis obtained from the orbicularis oculi and oris muscles without force monitoring can be used to differentiate pathological processes affecting the face.The interference pattern from orbicularis oculi and orbicularis oris was studied using a concentric needle electrode ...

ORBICULARIS ORIS MUSCLE IN DOUBLE HARELIP
Archives of Surgery, 1946DURING operations on 3 patients with double harelip, a modification of one of the usual plastic procedures was evolved. 1 The essential feature of this change was to join the sphincter muscles of each side across the premaxilla, and, to this end, it was necessary to cut deeply into the lip at right angles to its edge in order that a flap of sufficient ...

Innervation of the orbicularis oris muscle by the hypoglossal nucleus in rabbit
Experimental Neurology, 1980Abstract Unilateral orbicularis oris muscle of five albino rabbits was injected with horseradish peroxidase (HRP), which appeared in a number of cells of the ipsilateral facial nucleus. No granule of HRP was detected in cells of the hypoglossal nucleus.
