Photogrammetry of the Muscles of Facial Expression

Cells Tissues Organs, 1988
The present study has attempted to determine the volume, square measure as well as length, width and thickness of the individual muscles of facial expression by photogrammetry. 15 fresh male head specimens were employed for a careful dissection of muscle layers. The volume was measured using the immersion procedure.

Pressure pain threshold of the cervico-facial muscles in healthy elderly people: the role of gender, age and dominance.

Gerodontology, 2015
OBJECTIVE The aim of this study was to assess the impact of age on pressure pain threshold (PPT) of cervico-facial muscles in healthy geriatric subjects and to investigate the role of gender and dominance on nociception.

Sonoanatomy of the muscles of facial expression

Surgical and Radiologic Anatomy, 1988
Primary anatomic studies served for identification and differentiation of the individual mimetic muscles. As a second step, we investigated the clinical potential of ultrasound imaging to visualize the mimetic musculature in 15 volunteers. This examination technique was used to diagnose pathological alterations, especially associated with facial palsy.

Effect of Unilateral Partial Facial Paralysis on Periosteal Growth at the Muscle-Bone Interface of Facial Muscles and Facial Bones

Plastic and Reconstructive Surgery, 2003
In a previous study, the influence of the midfacial musculature upon growth and development of the maxilla and mandible was established macroscopically. Dry skull measurements revealed a reduced premaxillary, maxillary, mandibular, and anterior corpus length with a simultaneous increase in mandibular ramal height on the paralyzed side.

A practical review of the muscles of facial mimicry with special emphasis on the superficial musculoaponeurotic system.

AJR. American journal of roentgenology, 2015
OBJECTIVE In this article, we elaborate a practical approach to superficial facial anatomy enabling easy identification of the facial mimic muscles by classifying them according to their shared common insertion sites.

Facial Action Coding System

, 2015
The Facial Action Coding System (FACS) is a widely used protocol for recognizing and labelling facial expression by describing the movement of muscles of the face.

EMG study for perioral facial muscles function during mastication.

Journal of Oral Rehabilitation, 2008
This study aimed to clarify the temporal and quantitative modulation in the orbicularis oris (OO) and buccinator (BUC) muscle activities during mastication. Ten healthy males (26.9 +/- 1.0 years) participated. Electromyograms (EMGs) of the facial muscles

Muscle-Nerve-Muscle Grafting for Facial Reanimation in Rats

Annals of Otology, Rhinology & Laryngology, 2017
Objective: Facial paralysis is a devastating condition leaving patients with a myriad of aesthetic and functional consequences. Muscle-nerve-muscle (MNM) neurotization is a reinnervation technique that involves implanting an autogenous nerve graft as a conduit between an innervated “donor” muscle and a denervated “recipient” muscle. We investigated the

Somatotopic representation of facial muscles within the facial nucleus of the mouse. A study using the retrograde horseradish peroxidase and cell degeneration techniques.

Brain, Behavior and Evolution, 1984
The somatotopic representation of facial muscles within the facial nucleus was investigated by means of the retrograde horseradish peroxidase and cell degeneration techniques in the mouse. The nasolabial muscle is represented in the dorsolateral, lateral,

FACIAL PARALYSIS AND MUSCLE-RELAXANT ANESTHESIA

Archives of Otolaryngology - Head and Neck Surgery, 1956
THE FOLLOWING case report is presented primarily to forewarn otologists of the insidious danger of using succinylcholine-drip muscle-relaxant anesthesia in any surgical procedure where the identification of the seventh cranial nerve is important to its preservation. REPORT OF CASE A 32-year-old woman had chronic left mastoiditis of 10 years' duration.
