BACKGROUND: The use of the masseteric nerve has been escalated as a donor nerve for facial reanimation in facial palsy patient (Wang et al., 2014; Manktelow et al., 2006; Klebuc, 2011; Bianchi et al., 2012; Zuker et al., 2000; Bae et al., 2006; Terzis, Konofaos, 2013; Terzis, Olivares, 2009; Bianchi et al., 2014). Previous studies had been done in Euro-Caucasian cadavers (Kaya et al., 2014). However, difference in anatomical details does exist between Asian and Euro-Caucasian population (Tzou et al...

Axel Sahovaler, David Yeh, John Yoo
Facial Paralysis (FP) profoundly impairs the life of individuals, both functionally and psychosocially. Surgical approaches to treat this condition are myriad, but the ultimate goal is to restore symmetry and movement. Ablative surgery for tumors of the head and neck region are amongst the most common etiologies causing FP and this group of patients represents unique challenges. Surgical defects may have multiple competing reconstructive requirements and addressing the FP must be considered in this context...

Facial expression of emotion is a foundational aspect of social interaction and nonverbal communication. In this study, we use a computer-animated 3D facial tool to investigate how dynamic properties of a smile are perceived. We created smile animations where we systematically manipulated the smile's angle, extent, dental show, and dynamic symmetry. Then we asked a diverse sample of 802 participants to rate the smiles in terms of their effectiveness, genuineness, pleasantness, and perceived emotional intent...

Gang Chen, Wenjin Wang, Wei Wang, Wei Ding, Xianxian Yang
BACKGROUND: Masseter-to-facial nerve transfer is a highly efficient technique for reanimating paralyzed muscle and has been reported to restore facial symmetry at rest. However, no systematic studies have been performed, and the effects of preoperative droop oral commissure on postoperative symmetry at rest have rarely been reported. METHODS: The authors retrospectively analyzed 35 patients with masseteric-facial nerve anastomosis and assessed the quality and quantity of the dynamic recovery and the oral commissure symmetry at rest...

PURPOSE OF REVIEW: To review recent literature pertaining to the use of masseteric-facial nerve neurorrhaphy (MFNN) for facial reanimation in patients with facial paralysis. RECENT FINDINGS: First, MFNN effectively restores some midface tone and function, including the ability to smile. Second, use of the masseteric nerve minimizes synkinesis, dysarthria, and dysphagia that frequently occur after hypoglossal-facial nerve neurorrhaphy. Third, concurrent cable grafting to the zygomatic branch from an intact proximal facial nerve remnant - when available - can restore dynamic eye closure...

The current concepts in the aesthetic and functional reconstruction of complex oromandibular defects are presented with a case of a patient with self-inflicted gunshot wound to the face. The patient presented with a 6 cm composite mandibular defect; the buccomandibular and suborbital aesthetic zones of the cheek along with the mucosa lining, and the ipsilateral facial musculature were missing. A rapid prototyping model of the facial skeleton was used to assist in preoperative planning. A single stage reconstruction with two free flaps was planned; a free fibula osseous flap to reconstruct the mandibular defect, and a free chimeric ALT/functioning vastus lateralis muscle...

BACKGROUND: Unilateral established or congenital facial palsies are usually treated with neuromuscular transplantation to reanimate the impaired side of the face. One of the most debated points is the motor nerve to choose for the reinnervation of the transplant. Contra-lateral healthy facial nerve is usually preferred, but in selected cases motor nerve to masseter is considered a valuable option. However only a few clinical studies focused on quality of life in this subset of patients are available in literature...

BACKGROUND: The immediate reconstruction of the face in the setting of radical parotidectomy for malignancy represents a particular challenge. We present a novel technique using 2 sections of the vastus lateralis muscle as a chimeric flap in combination with the anterolateral thigh (ALT) fasciocutaneous flap to achieve midface reanimation and eye closure after radical parotidectomy. METHODS: The harvest technique in view of variations in chimeric muscle components, vascular pedicles, and neural coaptations is described herein...

Studies of the last twenty years on the motor and premotor cortices of primates demonstrated that the motor system is involved in the control and initiation of movements, and in higher cognitive processes, such as action understanding, imitation, and empathy. Mirror neurons are only one example of such theoretical shift. Their properties demonstrate that motor and sensory processing are coupled in the brain. Such knowledge has been also central for designing new neurorehabilitative therapies for patients suffering from brain injuries and consequent motor deficits...

Facial paralysis can be a devastating condition, causing disfiguring facial droop, slurred speech, eye dryness, scarring and blindness. This study investigated the utility of closed-loop functional electric stimulation (FES) for reanimating paralyzed facial muscles in a quantitative rodent model. The right buccal and marginal mandibular branches of the rat facial nerve were transected for selective, unilateral paralysis of whisker muscles. Microwire electrodes were implanted bilaterally into the facial musculature for FES and electromyographic (EMG) recording...

Peripheral paralysis of the facial nerve is the most frequent of all cranial nerve disorders. Despite advances in facial surgery, the functional and aesthetic reconstruction of a paralyzed face remains a challenge. Graduated minimally invasive facial reanimation is based on a modular principle. According to the patients' needs, precondition, and expectations, the following modules can be performed: temporalis muscle transposition and facelift, nasal valve suspension, endoscopic brow lift, and eyelid reconstruction...

BACKGROUND: People with chronic tetraplegia, due to high-cervical spinal cord injury, can regain limb movements through coordinated electrical stimulation of peripheral muscles and nerves, known as functional electrical stimulation (FES). Users typically command FES systems through other preserved, but unrelated and limited in number, volitional movements (eg, facial muscle activity, head movements, shoulder shrugs). We report the findings of an individual with traumatic high-cervical spinal cord injury who coordinated reaching and grasping movements using his own paralysed arm and hand, reanimated through implanted FES, and commanded using his own cortical signals through an intracortical brain-computer interface (iBCI)...

OBJECTIVES: Surgical rehabilitation of facial palsy is challenging as each case is unique and success rate is often unpredictable. In one technique, temporalis is elevated from origin preserving vessels, and this elevation increases the length which is tunneled into buccal tissues (pull-through technique, Group A). In the other technique, a harvested fascia lata is attached to temporalis after a coronoidectomy release and the fascia lata is attached to the modiolus (Group B). The aim of this study is to compare the two different surgical techniques...

A survey on the feasibility of surface electromyography (EMG) measurements in facial pacing is presented. Pacing for unilateral facial paralysis consists of the measurement of activity from the healthy side of the face and functional electrical stimulation to reanimate the paralyzed one. The goal of this study is to evaluate the feasibility of surface EMG as a measurement method to detect muscle activations and to determine their intensities. Prior work is discussed, and results from experiments where 12 participants carried out a set of facial movements are presented...

BACKGROUND: Two-stage facial reanimation procedures with a cross-facial nerve graft often have unsatisfactory results in the older patient. Although the cause of result variability is likely multifactorial, some studies suggest that increased donor nerve axonal load improves function of a free muscle transfer after a cross-facial nerve graft. This study attempts to characterize the relationship between age and facial nerve axonal load. METHODS: Sixty-three fresh cadaveric heads were dissected to expose the facial nerve...

BACKGROUND: Free functional muscle transfers represent the 'criterion standard' for smile reconstruction in facial paralysis. The gracilis muscle is a common donor muscle; however, no data exist regarding the volume of the muscle tissue that is necessary for symmetric commissure excursion. METHODS: All patients with facial paralysis receiving a free functional muscle transfer for facial reanimation surgery between January 2009 and November 2015 were retrospectively analysed...
