Application of an Intraoperative Neuromonitoring System Using a Surface Pressure Sensor in Parotid Surgery: A Rabbit Model Study [PDF]

Clinical and Experimental Otorhinolaryngology, 2021
Objectives Facial nerve monitoring (FNM) can be used to identify the facial nerve, to obtain information regarding its course, and to evaluate its status during parotidectomy. However, there has been disagreement regarding the efficacy of FNM in reducing

Motor Evoked Potentials Improve Targeting in Deep Brain Stimulation Surgery

Neuromodulation: Technology at the Neural Interface, EarlyView., 2021
Abstract Objectives One of the main challenges posed by the surgical deep brain stimulation (DBS) procedure is the successful targeting of the structures of interest and avoidance of side effects, especially in asleep surgery. Here, intraoperative motor evoked potentials (MEPs) might serve as tool to identify the pyramidal tract.

Local Administration of Insulin-Like Growth Factor 1 Attenuates Neuronal Loss and Muscle Atrophy in a Guinea Pig Model of Severe Facial Paralysis. [PDF]

Laryngoscope Investig Otolaryngol
ABSTRACT Objective To investigate the effects of locally administered insulin‐like growth factor‐1 (IGF‐1) on facial motor neurons, nerve fibers, and muscles in a severe facial paralysis model. Methods Severe unilateral facial paralysis was induced in guinea pigs (Cavia porcellus) by 5‐s cryospray injury to the facial nerve canal with the bony wall ...

Imaging of Facial Muscles in Facioscapulohumeral Muscular Dystrophy: An Exploratory Study Comparing Magnetic Resonance Imaging and Ultrasound. [PDF]

Muscle Nerve
ABSTRACT Aims Facioscapulohumeral muscular dystrophy (FSHD) is a genetic progressive muscle disorder often presenting with facial weakness. However, imaging studies specifically evaluating facial muscle involvement and its relationship with clinical severity remain limited. This preliminary study explored magnetic resonance imaging (MRI) and ultrasound

Descriptive, comparative, and functional anatomy of the facial musculature in cattle (Bos taurus). [PDF]

Anat Rec (Hoboken)
Abstract Facial expressions can provide insight into animal emotions and pain, but no standardized system for assessing the entire facial display in cattle (Bos taurus Linnaeus) exists. The Facial Action Coding System (FACS), originally developed for humans, identifies distinct facial movements based on mimetic muscles.

Variant muscle fibers connecting the orbicularis oculi to the orbicularis oris: case report

Anatomy & Cell Biology, 2022
The orbicularis oculi (OOc) is a sphincteric muscle of the eyelids, whereas contraction of the orbicularis oris (OOr), another sphincteric muscle, causes narrowing of the lips. Facial muscle fibers normally blend with adjacent muscles. However, muscle fibers connecting the various facial muscles that have different actions and that are located at ...
