Apichai Angspatt, Chirayu Pannanusorn
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...

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...

Facioscapulohumeral Muscular Dystrophy is a common form of muscular dystrophy that presents clinically with progressive weakness of the facial, scapular, and humeral muscles, with later involvement of the trunk and lower extremities. While typically inherited as autosomal dominant, facioscapulohumeral muscular dystrophy (FSHD) has a complex genetic and epigenetic etiology that has only recently been well described. The most prevalent form of the disease, FSHD1, is associated with the contraction of the D4Z4 microsatellite repeat array located on a permissive 4qA chromosome...

The purpose of this study was to determine the incidence of an anterior extension of the parotid gland, such as an accessory parotid gland (APG) or facial process (FP) and to evaluate its characteristics on computed tomography (CT) scans. We reviewed CT scans of 1,600 parotid glands from 800 patients. An APG on CT was defined as a soft-tissue mass of the same density as the main parotid gland, located at the anterior part of the main parotid gland, and completely separate from the main parotid gland. An FP was defined as a lobe of the parotid gland protruding anteriorly over the anterior edge of the ramus of the mandible on CT and showing continuity with the main gland...

With advances in diagnostic technology, radiologic diagnostic methods have been used more frequently, and physical examination may be neglected. The authors report a case of pediatric medial orbital trapdoor fracture in which the surgery was delayed because computed tomography (CT) findings did not indicate bone displacement, incarceration of rectus muscle, or soft tissue herniation. A healthy 6-year-old boy was admitted to the emergency room for right eyebrow laceration. We could not check eyeball movement or diplopia, because the patient was irritable...

A 25-years-old woman with mandibular prognathism underwent a mandibular setback by way of mandibular sagittal split ramus osteotomy (MSSRO). After 2 days of operation, she developed difficulty of closing her right eye. The blink reflex test and motor nerve conduction study of the right orbicularis oris muscle were revealed right facial neuropathy of unknown origin and House-Brackmann facial nerve grading system (HBFNGS) grade V. For treatment, we initially prescribed oral prednisolone and nimodipine including physical therapy...

Dermatomyositis (DM) is a rare autoimmune condition which predominantly affects females in the fifth and sixth decades of life. DM presents acutely or progressively as painless proximal skeletal muscle weakness and can be associated with a heliotropic rash around the eyes, and Gottron's papules on extensor surfaces of the hands. While the pathophysiology of DM is still unclear, abnormal T- and B-cell immune activity has been reported. DM has been associated with malignancy and has been shown to appear before, concurrently with, or after diagnosis of cancer...

Background: Facial wounds are challenging for dermatologic surgeons, particularly traumatic facial wounds, because they can yield disfiguring scars. To obtain good results, narrow needles and sutures are needed. Hair filaments have a very small diameter (0.06-0.1 mm) and could serve as suture threads for facial wounds. Objective: To determine the aesthetic outcomes by using autologous hair to suture facial wounds. Patients and Methods: This case series study examined the aesthetic outcomes of all consecutive female patients with traumatic facial wounds who underwent autologous hair-based stitching in 2009-2016...

The nonsyndromic cleft is one of the most frequent congenital defects in humans. Clinical data demonstrated improved and almost scarless neonatal healing of reparative surgery. Based on our previous results on crosstalk between neonatal fibroblasts and adult keratinocytes, the present study focused on characterization of fibroblasts prepared from cleft lip tissue samples of neonates and older children, and compared them with samples isolated from normal adult skin (face and breast) and scars. Although subtle variances in expression profiles of children and neonates were observed, the two groups differed significantly from adult cells...

Free extensor digitorum brevis muscle flap in facial paralysis, and the second metatarsophalangeal joint flap is used at the temporomandibular joint reconstruction for a long time. Anatomically, these flaps can be harvested through even the same pedicle flap even on the same regions. Literature is available of their usage along with the use of hand and upper extremity reconstruction. Unlike this example, the authors have used these flaps in maxillofacial region where facial paralysis and temporomandibular joint reconstruction will be performed together...

Age influences incidence and prognosis of Guillain Barre Syndrome (GBS), common cause of ascending areflexic quadriparesis. Dedicated studies on elderly GBS are infrequent. This study aimed to describe clinical features and outcome at hospital-discharge in patients aged≥60years with GBS. Medical records of 70 elderly GBS over 15years were analysed. Mean symptom-duration was 5.78±4.5days and onset-to-peak 5.14±4.4days. Antecedent events preceded GBS by 8.07±9.9days and included: fever (n=19), respiratory infection (n=6), and gastroenteritis (n=5)...

BACKGROUND AND OBJECTIVES: Facial paralysis causes excruciating impairments including facial asymmetry, limited eye closure, oral incontinence and social dysfunction. Modern plastic surgical reconstructions render favorable results with well-perfused dynamic muscle flaps. Post-operative tissue monitoring is a critical determinant for success. Contrast-enhanced Ultrasound (CEUS) and elastography have proven superior properties to evaluate tissue perfusion in various organs. We evaluated their role for functional muscle flaps positioned at the sub-skin level in facial palsy patients...

This health technology assessment evaluated the efficacy of pharmacological treatment in patients with oro-facial pain. Randomised controlled trials were included if they reported pharmacological treatment in patients ≥18 years with chronic (≥3 months) oro-facial pain. Patients were divided into subgroups: TMD-muscle [temporomandibular disorders (TMD) mainly associated with myalgia]; TMD-joint (TMD mainly associated with temporomandibular joint pain); and burning mouth syndrome (BMS). The primary outcome was pain intensity reduction after pharmacological treatment...

BACKGROUND: Microvascular decompression (MVD) is the most useful treatment for hemifacial spasm (HFS). During MVD surgery, abnormal muscle response (AMR) is widely used. ZL response (ZLR) is a new monitoring method for HFS. We compared the effect of AMR plus ZLR and simple AMR. METHODS: We performed a retrospective study of 1,868 cases of HFS treated using intraoperative monitoring between January 2013 and December 2015. Among the 1,868 cases, 896 patients underwent simple AMR monitoring and 972 underwent combined intraoperative monitoring of AMR and ZLR...

The aim of this study was to assess the reproducibility of non-verbal facial expressions in unilateral facial paralysis using dynamic four-dimensional (4D) imaging. The Di4D system was used to record five facial expressions of 20 adult patients. The system captured 60 three-dimensional (3D) images per second; each facial expression took 3-4seconds which was recorded in real time. Thus a set of 180 3D facial images was generated for each expression. The procedure was repeated after 30min to assess the reproducibility of the expressions...

According to embodiment theories, language and emotion affect each other. In line with this, several previous studies investigated changes in bodily responses including facial expressions, heart rate or skin conductance during affective evaluation of emotional words and sentences. This study investigates the embodiment of emotional word processing from a social perspective by experimentally manipulating the emotional valence of a word and its personal reference. Stimuli consisted of pronoun-noun pairs, i.e...

The aim of this study was to clarify the anatomical relationship between the buccinator and the temporalis in order to improve understanding of the precise and coordinated movements of the mouth and the mandible. The buccinator and the temporalis were investigated in 72 hemifaces from Korean cadavers. Removing the buccal fat pad from the buccinator revealed that the fascia encircled the space between the superficial and deep tendons of the temporalis laterally, and the external surface of the buccinator medially in all specimens (100%)...

Hemifacial spasm is a hyperactive cranial nerve disease mainly characterized by unilateral facial muscles paroxysmal, involuntary, irregular and clonic convulsion. Standard microvascular decompression is currently the most effective solution. During operation, it is pivotal to conduct a sharp dissection of arachnoid membrane around the caudal cranial nerves and facial, auditory nerves for fully exposure of pontomedullary sulcus, and lateral pontine region. In this article, the authors demonstrate a hemifacial spasm patient who underwent microvascular decompression successfully in their department...

PURPOSE: Functional inoperability in advanced oral cancer is difficult to assess preoperatively. To assess functions of lips and tongue, biomechanical models are required. Apart from adjusting generic models to individual anatomy, muscle activation patterns (MAPs) driving patient-specific functional movements are necessary to predict remaining functional outcome. We aim to evaluate how volunteer-specific MAPs derived from surface electromyographic (sEMG) signals control a biomechanical face model...
