Steinert's disease or Myotonic Dystrophy type 1 (DM1) is an autosomal dominant multisystemic disorder characterized by myotonia, muscle and facial weakness, cataracts, cognitive, endocrine and gastrointestinal involvement, and cardiac conduction abnormalities. Although mild myocardial dysfunction may be detected in this syndrome with age, overt myocardial dysfunction with heart failure is not frequent. Cardiac resynchronization therapy is an effective treatment to improve morbidity and reduce mortality in patients with DM1 showing intra-ventricular conduction delay and/or congestive heart failure...

AIMS: To assess the modulatory effects of experimental psychological stress on the somatosensory evaluation of myofascial temporomandibular disorder (TMD) patients. METHODS: A total of 20 women with myofascial TMD and 20 age-matched healthy women were assessed by means of a standardized battery of quantitative sensory testing. Cold detection threshold (CDT), warm detection threshold (WDT), cold pain threshold (CPT), heat pain threshold (HPT), mechanical pain threshold (MPT), wind-up ratio (WUR), and pressure pain threshold (PPT) were performed on the facial skin overlying the masseter muscle...

Orofacial pain includes neuronal pathways that project from the trigeminal nucleus to and through the thalamus. What role the ventroposterior thalamic complex (VP) has on orofacial pain transmission is not understood. To begin to address this question an inhibitory G protein (Gi) designer receptor exclusively activated by a designer drug (DREADD) was transfected in cells of the VP using adeno-associated virus isotype 8. Virus infected cells were identified by a fluorescent tag and immunostaining. Cells were silenced after injecting the designer drug clozapine-n-oxide, which binds the designer receptor activating Gi ...

Facial electromyography research shows that corrugator supercilii ("frowning muscle") activity tracks the emotional valence of linguistic stimuli. Grounded or embodied accounts of language processing take such activity to reflect the simulation or "reenactment" of emotion, as part of the retrieval of word meaning (e.g., of "furious") and/or of building a situation model (e.g., for "Mark is furious"). However, the same muscle also expresses our primary emotional evaluation of things we encounter...

Background: Arnold Chiari malformation (ACM) is characterized by an anatomical defect at the base of the skull where the cerebellum and the spinal cord herniate through the foramen magnum into the cervical spinal canal. Among the subtypes of the condition, ACM type I (ACM-I) is particularly outstanding because of the severity of symptoms. This study aimed to analyze the orofacial clinical manifestations of patients with ACM-I, and discuss their demographic distribution and clinical features in light of the literature...

Background Ameloblastoma is a rare benign odontogenic tumor with a metastasis rate estimated at 2% of cases, mainly involving the lung (80%) and lymph nodes (20%). Methods We hereby present the case of a 26 year old patient with a history of locally recurrent mandibular ameloblastoma who developed a temporal intracranial ameloblastoma tumor requiring a collaborative neurosurgical and maxillo-facial radical surgical approach. Conclusion Although ameloblastomas are histologically benign, the temporal topography questions the dissemination pathophysiology of the tumor (metastasis or local extension through temporal muscle fibers), mainly relevant in cases of multiple recurrences...

Background: The premise of minimally invasive surgery (MIS) is to minimize facial and muscle injury in order to enhance recovery from surgery. Robotic MIS surgery for resection of tumors in solid organs is gaining traction, though clear superiority of this approach is lacking and robotic surgery is more expensive. Our philosophy in robotically-assisted hepatectomy has been to employ this approach for cases where location of tumors make difficult a classical laparoscopic approach (superior/posterior tumors), and cases where the incision for an open operation dominates the course of recovery...

Background: Bilateral Tessier number 3 clefts are extremely rare, and their surgical treatments have not been well established. Case presentation: The authors describe the case of a patient with a right Tessier number 3, 11 facial cleft with microphthalmia, a left Tessier number 3 facial cleft with anophthalmia, and cleft palate. We repaired simultaneously the bilateral soft tissue clefts by premaxillary repositioning, cleft lip repair, facial cleft repair by nasal lengthening, midfacial advancement, and an upper eyelid transposition flap with repositioning both the medial canthi...

Facial actions are key elements of non-verbal behavior. Perceivers' reactions to others' facial expressions often represent a match or mirroring (e.g., they smile to a smile). However, the information conveyed by an expression depends on context. Thus, when shown by an opponent, a smile conveys bad news and evokes frowning. The availability of anthropomorphic agents capable of facial actions raises the question of how people respond to such agents in social context. We explored this issue in a study where participants played a strategic game with or against a facially expressive android...

Cutaneous insertion of the facial mimic muscles concerns, at different levels, the superficial fascia of that region. A superficial musculoaponeurotic system is described at face level that facilitates skin insertion of the facial expression muscles through the superficial fascia that acquires particular functional aspects in each region of the face. The existence of a musculofascial system is seen controversial among anatomists, which is why the purpose of this study is to establish its existence at the oral region...

PURPOSE: Previous studies evidenced that orotracheal intubation without neuromuscular blockers is feasible in children and has some potential advantages. Remifentanil has favorable pharmacodynamic and pharmacokinetic properties as an opioid for orotracheal intubation, but its dose for excellent intubation conditions when co-administered with propofol has not been established. This study was designed to find the minimum effective dose of remifentanil for excellent intubation conditions of children when co-administered with propofol, without neuromuscular relaxant drugs...

Congenital muscle diseases, such as myopathies or dystrophies, occur relatively frequently, with estimated incidences of up to 4.7 per 100 000 newborns. To diagnose congenital diseases in the early stages of pregnancy, and to interpret the results of increasingly advanced in utero imaging techniques, a profound knowledge of normal human morphological development of the locomotor system and the nervous system is necessary. Muscular development, however, is an often neglected topic or is only described in a general way in embryology textbooks and papers...

PURPOSE: Severe physical facial deformities due to surgical interventions can have significant psychosocial consequences to patient's relationships with friends and family and thus, has a considerable impact on their quality of life. We have developed a 3D prosthesis for a 56-year-old woman diagnosed with epidermoid carcinoma at the right hemiface, to improve her quality of life. METHODS: The patient started radiotherapy with modulated intensity. To deal with the advance of the process, a maxilectomy of supra structure with modified radical cervical emptying on the right hemiface was performed...

During nerve reconstruction, nerves of different thicknesses are often sutured together using end-to-side neurorrhaphy and end-to-end neurorrhaphy techniques. In this study, the effect of the type of neurorrhaphy on the number and diameter of regenerated axon fibers was studied in a rat facial nerve repair model. An inflow-type end-to-side and end-to-end neurorrhaphy model with nerve stumps of different thicknesses (2:1 diameter ratio) was created in the facial nerve of 14 adult male Sprague-Dawley rats. After 6 and 12 weeks, nerve regeneration was evaluated in the rats using the following outcomes: total number of myelinated axons, average minor axis diameter of the myelinated axons in the central and peripheral sections, and axon regeneration rate...

Facial artery perforator flaps have been recently reported by different authors for perioral, nasal alar and cheek defects, but not for intraoral reconstruction. We have extended the use of the facial artery perforator flap in a 56-year-old man with a squamous cell carcinoma of left mouth floor, who was submitted to tumor resection with marginal mandibulectomy and left supraomohyoid neck dissection. The flap was designed according to the size of the defect (5 × 3 cm), centered on the perforator to create a symmetric flap and was tunnelled intraorally by means of a 90° rotation...

According to a long-standing hypothesis in motor control, complex body motion is organized in terms of movement primitives, reducing massively the dimensionality of the underlying control problems. For body movements, this low-dimensional organization has been convincingly demonstrated by the learning of low-dimensional representations from kinematic and EMG data. In contrast, the effective dimensionality of dynamic facial expressions is unknown, and dominant analysis approaches have been based on heuristically defined facial "action units," which reflect contributions of individual face muscles...

This study investigated the effects of Furlow palatoplasty on children with submucous cleft palate (SMCP) and identified surgical indications by comparing SMCP and control patients. Twenty-three SMCP children (average age 28.9 months) who were nonsyndromic and underwent surgery between April 2010 and December 2016 were included. Facial computed tomography (CT) was performed preoperatively and at least 1 year postoperatively after a language test. Facial CT measurements were taken for 140 children aged 0-6 years without deformities (control group)...

A 45-year-old Asian man presented with acute-onset periorbital and facial edema associated with pyrexia. Muscle weakness was absent. Initial laboratory investigations showed an inflammatory reaction, while screening for infections was negative. Serum muscle enzyme levels were normal. He was hospitalized and treated empirically with antibiotics and corticosteroids, pending the result of facial skin and muscle biopsy. He showed a good clinical and laboratory response but an attempt to discontinue corticosteroids led to a prompt relapse of facial edema and pyrexia, associated with rising laboratory indices of inflammation...

The temporalis muscle transposition is a reliable, one-stage reanimation technique for longstanding facial paralysis. In the variation described by Rubin, the muscle is released from the temporal bone and folded over the zygomatic arch towards the modiolus. This results in unsightly temporal hollowing and zygomatic bulging. We present a modification of this technique, which preserves the temporal fat pad in its anatomical location as well as conceals temporal hollowing and prevents zygomatic bulging. The data of 23 patients treated with this modification were analysed...

OBJECTIVE: To observe the clinical effect difference between special penetration needling and conventional penetration needling for the refractory peripheral facial paralysis. METHODS: A total of 97 patients with intractable facial paralysis were randomized into an observation group (49 cases and 2 dropping) and a control group (48 cases and 4 dropping). In the observation group, special penetration needling at an angle about 45° between the penetration needle and paralysis muscle bundle was used, Yangbai (GB 14) through Touwei (ST 8), Yangbai (GB 14) through Shangxing (GV 23), Sizhukong (TE 23) through Yuyao (EX-HN 4), Qianzhen (Extra) through Yingxiang (LI 20), mutual penetration between Yingxiang (LI 20) and Jiache (ST 6)...
