Abstract
THE AIM OF THE STUDY Was the increasing the effectiveness of treatment and prevention of postoperative complications in the patients with benign tumors of the parotid salivary gland through the combined use of medications, acupuncture, hirudotherapy and a complex of physiotherapy. MATERIALS AND METHODS The study comprised 94 patients with postoperative complications after surgical treatment of benign tumors of the parotid salivary gland. All patients suffering from paresis of facial muscles were prescribed a physiotherapy complex developed during the study consisting of two series of exercises with alternating execution of the series every other day. The exercises begin with the upper third of the face, gradually descending to the lower third. A series of exercises is performed every hour and a half, the session duration is twenty minutes, the course is 14 days. The exercises are performed by the patient in front of the mirror, gently and at a slow pace. RESULTS The duration of the recovery period of motor function of the facial muscles on the affected side was 31.2±19.6 days, with the amplitude of the M-response 1.45±0.28 mV, the duration of the M-response 8.04±0.27 ms and the latent time during EMG 3.18±0.86 ms. Conclusion. The combined treatment, which included surgical and conservative treatment complex with methods of acupuncture, hirudotherapy and physiotherapy, was significantly more effective (p<0.05) in terms of the severity of paresis of facial muscles than in the control group.

Abstract
There are limited MRI studies of craniofacial and velopharyngeal features in children with 22q11.2 deletion syndrome (22q11.2DS) and to date, none have explored the potential relationship between these features and the speech phenotype. The purpose of this study was to examine the relationship between craniofacial and related velopharyngeal structures in children with 22q11.2DS and to assess their correlation to resonance features using an unsedated MRI protocol. Fifteen children with 22q11.2DS and 15 age- and sex-matched controls with normal velopharyngeal anatomy (ages 4-12 years) successfully completed the study. Analysis of covariance was used to compare differences between the experimental (22q11.2DS) and control (children with normal anatomy) groups. Correlation analyses and regression models were also utilized. The 22q11.2DS group demonstrated significantly shorter nasion-to-sella, sella-to-basion, and basion-to-opisthion distances. The anterior cranial base angle was significantly more obtuse. The levator veli palatini (levator) muscle was significantly thinner and shorter, with an obtuse angle of origin in the 22q11.2DS group. Levator length was significantly correlated with the sella-to-basion measure and hypernasality was correlated with levator origin-to-origin distance. Preliminary results from this study indicate a significant association between hypernasality and levator origin-to-origin distance. Findings from the present study, provide an insight into the pathophysiology of velopharyngeal dysfunction related to this clinically complex population.

Abstract
Neurosarcoidosis when encountered by neurologists most commonly presents as cranial neuropathy, peripheral mononeuropathy,polyneuropathy, myopathy, meningitis or myelopathy. There are limited reports in the current literature on the cases of neurosarcoidosis patients presenting with ischaemic stroke. We discuss a 52-year-old patient with a known previous history of cutaneous sarcoidosis presenting with an acute third nerve palsy, facial weakness and ataxia. His magnetic resonance imaging (MRI) brain demonstrated focal signal changes in the midbrain consistent with an acute ischaemic event in the region of his third nucleus, suggesting a partial Claude syndrome presentation. Cerebrospinal fluid (CSF) examination demonstrated an elevated angiotensin-converting enzyme (ACE) level. We discuss the difficulties associated with confirming a diagnosis for his presentation and consider distinctions in stroke in neurosarcoid and its management in comparison to more common causes.

Abstract
This case is an addition to scarce literature available for a rare condition, chewing-induced task-specific dystonia. The patient was a 63-year-old woman who presented with a 4-year history of progressive difficulty in eating food only during chewing associated with abnormal facial grimaces without any difficulty in drinking, swallowing, speaking or singing. Examination revealed dystonia of facial muscles every time she chewed but absent during drinking and speaking. As movements were consistent and reproducible with the specific task, other differential diagnosis like motor tics, psychogenic disorder, tardive dystonia and parkinsonism syndrome were excluded leading to a diagnosis of task-specific facial dystonia triggered by chewing. Treatment was started with trihexyphenidyl and later on tetrabenazine was also added but she got only mild relief of symptoms. As she did not agreed for botulinum toxin therapy, so we continued with the same treatment without much improvement.

Abstract
OBJECTIVE Motor control of the muscles of the face, lips, and tongue of horn players has traditionally been described from externally observed phenomena. Developments in real-time, high-speed magnetic resonance imaging (MRI) extend the scope of study to include descriptive and quantitative information from within the mouth. We employed these developments to compare oral movement strategies between 12 elite horn players and 5 horn players with embouchure dystonia (ED). METHODS Serial images with an acquisition time of 33.3 ms were obtained from each subject as they performed 6 exercises on an MRI-compatible horn: 1) a slurred ascending harmonic sequence, 2) a slurred descending harmonic sequence, 3-6) sustained high and low notes, each performed softly and loudly. Temporal changes in pixel luminescence along a series of lines positioned within the oral cavity were calculated using a customized MATLAB toolkit. This allowed the extraction of temporal line profiles for comparative analyses between elite and dystonic horn players. RESULTS Differing motor strategies of controlling the tongue and jaw were observed during ascending and descending exercises. In ascending exercises, the elite players employed a strategy of elevation and anterior tongue displacement and elevation of the jaw, whereas dystonic players exhibited more variability in their responses. With descending exercises, both groups exhibited a lowering of the tongue and jaw, though this was more pronounced and consistent in the elite horn players. Sustained note exercises also elicited differences between groups. We suggest that elite strategies are more efficient and that the less-efficient patterns of dystonic players may exacerbate muscular tension with ED.

Abstract
After peripheral nerve injury, recovery of motor performance negatively correlates with the poly-innervation of neuromuscular junctions (NMJ) due to excessive sprouting of the terminal Schwann cells. Denervated muscles produce short-range diffusible sprouting stimuli, of which some are neurotrophic factors. Based on recent data that vibrissal whisking is restored perfectly during facial nerve regeneration in blind rats from the Sprague Dawley (SD)/RCS strain, we compared the expression of brain derived neurotrophic factor (BDNF), fibroblast growth factor-2 (FGF2), insulin growth factors 1 and 2 (IGF1, IGF2) and nerve growth factor (NGF) between SD/RCS and SD-rats with normal vision but poor recovery of whisking function after facial nerve injury. To establish which trophic factors might be responsible for proper NMJ-reinnervation, the transected facial nerve was surgically repaired (facial-facial anastomosis, FFA) for subsequent analysis of mRNA and proteins expressed in the levator labii superioris muscle. A complicated time course of expression included (1) a late rise in BDNF protein that followed earlier elevated gene expression, (2) an early increase in FGF2 and IGF2 protein after 2 days with sustained gene expression, (3) reduced IGF1 protein at 28 days coincident with decline of raised mRNA levels to baseline, and (4) reduced NGF protein between 2 and 14 days with maintained gene expression found in blind rats but not the rats with normal vision. These findings suggest that recovery of motor function after peripheral nerve injury is due, at least in part, to a complex regulation of lesion-associated neurotrophic factors and cytokines in denervated muscles. The increase of FGF-2 protein and concomittant decrease of NGF (with no significant changes in BDNF or IGF levels) during the first week following FFA in SD/RCS blind rats possibly prevents the distal branching of regenerating axons resulting in reduced poly-innervation of motor endplates.

Abstract
Myopathic changes are frequent a electrophysiological finding in patients with muscle specific tyrosine kinase (MuSK) positive myasthenia gravis (MG). The aim of this study was to explore the importance of quantitative electromyography (EMG) in the detection of myopathic changes in MuSK MG patients. Classical and quantitative EMG were performed in 31 MuSK and 28 acetylcholine receptor (AChR) positive MG patients, matched by sex, age, disease duration and severity. Classical EMG revealed the presence of myopathic changes more frequently in MuSK MG compared to AChR MG patients, especially in the facial muscles. Quantitative EMG registered myopathic lesions more frequently than classical EMG, but the frequency was similar between MuSK and AChR MG patients. Quantitative EMG revealed myopathic changes in the majority of both MuSK and AChR positive MG patients. This examination is sensitive, but it cannot be used to differentiate between MG patients belonging to the different disease groups. It should not be used in isolation. Rather, it should complement classical EMG in the detection of myopathic changes.

Abstract
PURPOSE Many children present with excessive blinking. Categorization, associated conditions, and prognosis are controversial. METHODS All children with excessive blinking were reviewed, excluding those with known uveitis, glaucoma, or obvious eyelid abnormalities. Parents were telephoned for follow-up. RESULTS No ocular pathology was identified in 31 of 34 children with excessive blinking (91%). Parents were able to report a specific cause of blinking in 7 (21%). In 24 of 34 (71%), parents reported complete resolution of excessive blinking. No new ophthalmologic diagnoses were uncovered on follow-up. CONCLUSIONS Episodes of excessive blinking rarely indicate neurologic disorders and frequently resolve spontaneously.

Abstract
The protection of sensitive structures (e.g., nerves) from iatrogenic damage is of major importance when performing laser surgical procedures. Especially in the head and neck area both function and esthetics can be affected to a great extent. Despite its many benefits, the surgical utilization of a laser is therefore still limited to superficial tissue ablation. A remote feedback system which guides the laser in a tissue-specific way would provide a remedy. In this context, it has been shown that nerval structures can be specifically recognized by their optical diffuse reflectance spectra both before and after laser ablation. However, for a translation of these findings to the actual laser ablation process, a nerve protection within the laser pulse is of utmost significance. Thus, it was the aim of the study to evaluate, if the process of Er:YAG laser surgery--which comes with spray water cooling, angulation of the probe (60°) and optical process emissions--interferes with optical tissue differentiation. For the first time, no stable conditions but the ongoing process of laser tissue ablation was examined. Therefore, six different tissue types (nerve, skin, muscle, fat, cortical and cancellous bone) were acquired from 15 pig heads. Measurements were performed during Er:YAG laser ablation. Diffuse reflectance spectra (4500, wavelength range: 350-650 nm) where acquired. Principal component analysis (PCA) and quadratic discriminant analysis (QDA) were calculated for classification purposes. The clinical highly relevant differentiation between nerve and bone was performed correctly with an AUC of 95.3% (cortial bone) respectively 92.4% (cancellous bone). The identification of nerve tissue against the biological very similar fat tissue yielded good results with an AUC value of 83.4% (sensitivity: 72.3%, specificity: of 82.3%). This clearly demonstrates that nerve identification by diffuse reflectance spectroscopy works reliably in the ongoing process of laser ablation in spite of the laser beam, spray water cooling and the tissue alterations entailed by tissue laser ablation. This is an essential step towards a clinical utilization.

Abstract
BACKGROUND If a child cries with an asymmetrical mouth it can be a sign of a nerve compression or a developmental defect in a facial muscle. In the latter case, a 22q11 deletion can be the cause, and multiple organs might be involved. CASE DESCRIPTION A 2-month-old infant was referred to the paediatric outpatient clinic because he had an asymmetrical mouth when crying or laughing. There were no further symptoms. Genetic investigations and ultrasounds of the heart and kidneys were performed to exclude an underlying syndrome caused by a 22q11 deletion. These revealed no significant findings. It appeared to be a case of isolated 'asymmetric crying facies' as a result of hypoplasia of the depressor anguli oris muscle. CONCLUSION An asymmetrical mouth in an infant can be a part of a genetic syndrome, in which there can be anomalies in multiple organ systems. For this reason, additional investigations are essential in cases of 'asymmetric crying facies'.

Abstract
The facial nerve is the most frequently damaged nerve in head and neck trauma. Patients undergoing facial nerve reconstruction often complain about disturbing abnormal synkinetic movements of the facial muscles (mass movements, synkinesis) which are thought to result from misguided collateral branching of regenerating motor axons and reinnervation of inappropriate muscles. Here, we examined whether use of an aorta Y-tube conduit during reconstructive surgery after facial nerve injury reduces synkinesis of orbicularis oris (blink reflex) and vibrissal (whisking) musculature. The abdominal aorta plus its bifurcation was harvested (N = 12) for Y-tube conduits. Animal groups comprised intact animals (Group 1), those receiving hypoglossal-facial nerve end-to-end coaptation alone (HFA; Group 2), and those receiving hypoglossal-facial nerve reconstruction using a Y-tube (HFA-Y-tube, Group 3). Videotape motion analysis at 4 months showed that HFA-Y-tube group showed a reduced synkinesis of eyelid and whisker movements compared to HFA alone.

Abstract
BACKGROUND A quantitative numerical method for assessing the extent and duration of the inhibitory action of botulinum neurotoxin type A on mimetic muscles would potentially enable more detailed evaluation of the overall efficacy of this aesthetic treatment. AIM To evaluate skin displacement analysis (SDA) as a tool for assessment of the extent and duration of effect of incobotulinumtoxinA on mimetic muscles in the glabellar region in routine daily practice. METHODS A total dose of 30 U incobotulinumtoxinA was injected into the fronto-glabellar region of 16 subjects. SDA was performed at baseline and during onset and recovery from incobotulinumtoxinA treatment at various timepoints up to 24 weeks after treatment. The reference point for SDA was located at the upper margin of the eyebrow, 30 mm lateral to the median line. To correlate and validate SDA results, semi-quantitative wrinkle score assessments were performed in parallel. RESULTS At baseline, the mean horizontal skin displacement was 5.4 mm (standard deviation: ± 1.4 mm). During onset of action after treatment, skin displacement values decreased from baseline (100%) by 46%, 85%, and 90% at day 2, week 1, and week 2, respectively. During recovery from incobotulinumtoxinA action, skin displacement values increased to 33%, 50%, and 93% of the baseline value at 6, 12, and 24 weeks after treatment, respectively. The inhibitory effect of incobotulinumtoxinA was highly variable among subjects, ranging from 25% to 68% of the baseline value 12 weeks after treatment. Overall agreement between SDA values and wrinkle scores was good. CONCLUSION SDA represents a novel, objective method for the quantitative evaluation of the effect of incobotulinumtoxinA on mimetic muscles underlying the fronto-glabellar region, and showed good correlation with wrinkle score assessments. Both SDA and wrinkle score indicated the persistence of treatment effects 24 weeks after injection.

Abstract
We report a case of cephalic tetanus which initially presented with acute lower motor neurone facial weakness. Tetanus is a rare diagnosis in the developed world but sporadic cases do occur. People born before 1960 in New Zealand are less likely to be immune. Judicious use of human tetanus immunoglobulin (TIG) and immunisation prevents the development of tetanus following injury and should always be considered in the elderly who are less likely to have immunity.

Abstract
Alveolar soft part sarcoma (ASPS) is a rare, histologically distinct, soft tissue malignancy with nonspecific clinical features usually described as a nonulcerated, painless, expanding mass. It has a pseudoalveolar appearance with clustered polygonal cells lacking central cohesion. It accounts for approximately 0.5 to 1% of all soft tissue sarcomas. It has a strong predilection for adolescents and young adults 15 to 35 years old, with a female predominance. In general, ASPS grows slowly, with a predilection for the trunk and extremities and rarely in the head and neck region. A literature review found only 11 cases of cheek ASPS that have been reported since 1952. This report describes the case of an unusually rapidly growing mass in the cheek of a 36-year-old woman. The superficial location of the mass led to early detection and treatment.

Abstract
Classic infantile Pompe disease is an inherited generalized glycogen storage disorder caused by deficiency of lysosomal acid α-glucosidase. If left untreated, patients die before one year of age. Although enzyme-replacement therapy (ERT) has significantly prolonged lifespan, it has also revealed new aspects of the disease. For up to 11 years, we investigated the frequency and consequences of facial-muscle weakness, speech disorders and dysphagia in long-term survivors. Sequential photographs were used to determine the timing and severity of facial-muscle weakness. Using standardized articulation tests and fibreoptic endoscopic evaluation of swallowing, we investigated speech and swallowing function in a subset of patients. This study included 11 patients with classic infantile Pompe disease. Median age at the start of ERT was 2.4 months (range 0.1-8.3 months), and median age at the end of the study was 4.3 years (range 7.7 months -12.2 years). All patients developed facial-muscle weakness before the age of 15 months. Speech was studied in four patients. Articulation was disordered, with hypernasal resonance and reduced speech intelligibility in all four. Swallowing function was studied in six patients, the most important findings being ineffective swallowing with residues of food (5/6), penetration or aspiration (3/6), and reduced pharyngeal and/or laryngeal sensibility (2/6). We conclude that facial-muscle weakness, speech disorders and dysphagia are common in long-term survivors receiving ERT for classic infantile Pompe disease. To improve speech and reduce the risk for aspiration, early treatment by a speech therapist and regular swallowing assessments are recommended.

Abstract
The activity of cytoskeletal proteins like talin, vinculin and nestin increases in muscle that regenerates. Little is known about their role or at least their expression in the process of regeneration in masticatory muscles of mdx mice, a model of Duchenne muscular dystrophy. To determine a potential role of cytoskeletal proteins in the regeneration process of mdx masticatory muscles, we examined the expression of talin 1, talin 2, vinculin and nestin in 100-day-old control and mdx mice using quantitative RT-PCR, Western blot analyses and histochemistry. The protein expression of talin 1, talin 2, nestin and vinculin in mdx muscles remained unchanged as compared with normal mice. However, in mdx masseter it was found a relative increase of nestin compared to controls. The protein expression of talin 1 and vinculin tended to be increased in mdx tongue and talin 2 to diminish in mdx masseter and temporal muscle. In mdx mice, we found significantly lower percentage of transcripts coding for nestin, talin 1, talin 2 and vinculin in masseter (p < 0.05) and temporal muscle (p < 0.001). In contrast, the mRNA expression of nestin was found to be increased in mdx tongue. Activated satellite cells, myoblasts and immature regenerated muscle fibres in mdx masseter and temporal revealed positive staining for nestin. The findings of the presented work suggest dystrophin-lack-associated changes in the expression of cytoskeletal proteins in mdx masticatory muscles could be compensatory for dystrophin absence. The expression of nestin may serve as an indicator for the regeneration in the orofacial muscles.

Abstract
OBJECTIVE The objective of our study was to review the different pathologies of the stomatognathic system that can present in musicians as a result of playing their instruments. DESIGN The National Library of Medicine's PubMed database was searched to identify all peer-reviewed articles in the English literature dealing with orofacial problems in musicians, using both subject headings such as MeSH terms (PubMed) and free text words in combination (oral, musician, violin, wind instruments, vocalists, orthodontic, tooth, temporomandibular disorders [TMD]). The identified studies were assessed independently by two authors. We included any instruments that involved the orofacial area: i.e., wind and brass instruments, vocalists, and violins and violas. RESULTS Thirty-two articles were selected that were of many different types (clinical reviews, longitudinal and transverse studies of therapeutic procedures, case-control studies). Among orofacial problems, the most common disorders that affect musicians are TMDs, herpes simplex virus infections, orthodontic problems, and problems with perioral musculature. CONCLUSIONS Musicians may suffer from pathological conditions that are worsened by their occupation due to excessive practice and stress. These conditions can cause permanent injuries that subsequently prevent the musicians from playing. Depending on the characteristics of the musical instrument and the way it is played, professional musicians generally show a propensity for buccodental problems.

Abstract
Using a combined morphofunctional approach, we recently found that polyinnervation of the neuromuscular junction (NMJ) is the critical factor for recovery of function after transection and suture of the facial nerve. Since polyinnervation is activity-dependent and can be manipulated, we tried to design a clinically feasible therapy by electrical stimulation or by soft tissue massage. First, electrical stimulation was applied to the transected facial nerve or to paralyzed facial muscles. Both procedures did not improve vibrissal motor performance (video-based motion analysis of whisking), failed to diminish polyinnervation, and even reduced the number of innervated NMJ to one-fifth of normal values. In contrast, gentle stroking of the paralyzed vibrissal muscles by hand resulted in full recovery of whisking. Manual stimulation depended on the intact sensory supply of the denervated muscle targets and was also effective after hypoglossal-facial anastomosis, after interpositional nerve grafting, when applied to the orbicularis oculi muscle and after transection and suture of the hypoglossal nerve. From these results, we conclude that manual stimulation is a noninvasive procedure with immediate potential for clinical rehabilitation following facial nerve reconstruction.

Abstract
CONCLUSION Long-term denervation-induced satellite cells (SCs) deficiency impairs facial muscle regenerative capacity. Delayed reinnervation can reactivate residual SCs to engage in muscle regeneration. However, the underlying mechanism remains to be elucidated. OBJECTIVE To evaluate the effects of denervation and delayed reinnervation on SCs in facial muscle. METHODS This was a prospective, randomized, controlled study in the rat facial nerve ligation and delayed decompression model. Animals were divided into denervation, 8-week-delay, and 16-week-delay reinnervation groups. Sham-operated animals served as a control group. Specific markers were used to investigate the differences in SC status, including quiescent (Pax7) and activated (myoD and myogenin) SCs and regenerative myofibers (embryonic myosin heavy chain, eMyHC). Quantitative assessment was performed by real-time PCR and Western blotting. RESULTS Activated SCs were detected 2-4 weeks after denervation and maintained for 4-8 weeks, accompanied by regenerating myofibers, whereas no SCs were detected beyond 20 weeks post-denervation. The myoD and myogenin up-regulation peaked 6-8 weeks after denervation and declined gradually to normal baseline 12 weeks after denervation. The 8-week-delay reinnervation group showed more activated SCs and regenerating myofibers than the 16-week-delay group, as well as greater up-regulation of myoD and myogenin (p < 0.05), suggesting reactivation of SCs for repair of adjacent fibers.

Abstract
The association of muscle tyrosine kinase (Musk) antibody with recurrent bulbar weakness in acetylcholine receptor antibody (Ach-R Ab) negative myasthenia gravis (MG) has been well documented. We describe 2 patients, a middle aged man and a 9-year-old girl, both seronegative for Ach R antibody who had recurrent bulbar weakness and MUSK antibody positivity. Patients made a full recovery from the acute episode with intravenous immunoglobulin (IV Ig) therapy. The peculiar clinical features of this condition and its management are discussed.

Abstract
PURPOSE CFEOM type 1 refers to a group of congenital eye movement disorders that is characterized by nonprogressive ophthalmoplegia affecting all the extraocular muscles. Individuals with the classic form of CFEOM are born with bilateral ptosis, infraducted eyes, and impossibility to raise their eyes above midline. This phenotype is often inherited as an autosomal dominant trait. CFEOM1 maps to the FEOM1 locus on chromosome 12 and is the consequence of mutations in the KIF21A gene. We analyzed three families and one sporadic case for potential genetic heterogeneity. METHODS Blood samples were collected from members of three families (Swiss, Turkish, and French origin) and one sporadic case (Iranian origin). In families, haplotype was tested for linkage to the autosomal dominant CFEOM1 locus on chromosome 12. Linkage studies were conducted using 2 polymorphic DNA microsatellite markers, D12S331 and D12S1048. Mutation analysis was performed by PCR amplification and bidirectional direct sequencing. RESULTS Haplotype analysis was compatible with linkage to the CFEOM1 locus in all affected members. Mutation analysis revealed the classical mutation R954W in all affected cases, including the sporadic case, regardless of their ethnic origin. The c.2860C>T base change was not observed in 100 individuals from various ethnic origins. CONCLUSIONS As reported, the classical c.2860C>T mutation represents a hotspot for mutation in various ethnic groups, including Swiss, Turkish, French, and Iranian patients. Sporadic cases are often due to neo-mutations as in our case. Mutation analysis is important, especially in sporadic cases, to correctly evaluate recurrence and transmission risks.

Abstract
CONTEXT Case reports and clinical trials have indicated that osteopathic manipulative treatment (OMT) may improve motor function and quality of life for children with cerebral palsy. OBJECTIVE To assess the effectiveness of osteopathy in the cranial field, myofascial release, or both versus acupuncture in children with moderate to severe spastic cerebral palsy, as measured by several outcomes instruments in a randomized controlled trial. METHODS Children between the ages of 20 months and 12 years with moderate to severe spastic cerebral palsy were enrolled in a single-blind, randomized wait-list control pilot study. There were three arms in the study: OMT (ie, osteopathy in the cranial field, myofascial release, or both, using direct or indirect methods), acupuncture, and control (ie, nontherapeutic attention). Children who were initially randomly assigned to the control arm were subsequently randomly reassigned to the intervention arms, increasing the sample size. Outcome measures included standard instruments used in the evaluation of children with cerebral palsy. Less traditional measures were also used, including serial evaluations by an independent blind osteopathic physician and visual analog scale assessments by an independent osteopathic physician and the parents or guardians. A total of 11 outcome variables were analyzed. RESULTS Fifty-five patients were included in the study. Individual analyses of the 11 outcome variables revealed statistically significant improvement in two mobility measures for patients who received OMT--the total score of Gross Motor Function Measurement and the mobility domain of Functional Independence Measure for Children (P<.05). No statistically significant improvements were seen among patients in the acupuncture treatment arm. CONCLUSIONS A series of treatments using osteopathy in the cranial field, myofascial release, or both improved motor function in children with moderate to severe spastic cerebral palsy. These results can be used to guide future research into the effectiveness of OMT or acupuncture in treating children with spastic cerebral palsy.

Abstract
Arachnoid cysts are rare lesions occurring anywhere in the cerebrospinal axis. The sylvian fissure remains the most favoured site for their occurrence, followed by cerebellopontine angle, suprasellar, and quadrigeminal cisterns. Retroclival arachnoid cysts are very rare. We report a retroclival arachnoid cyst with bilateral cerebellopontine angle extensions with hemifacial spasm in a 26-year-old woman. The patient underwent surgery and her hemifacial spasm improved.

Abstract
INTRODUCTION The aim of this study is to detect the problems related to wind instruments in order to determine the contributing factors. MATERIAL AND METHOD This study is a prospective study of a sample of Lebanese wind-instruments musicians. Questionnaire of 17 items about personal data, musical activities in general and specific problems related to wind instruments. RESULTS 340 response out of 400 (85%). Gender: male 100%. Age: 28.5 +/- 6.5 years (13-50). Practice of any physical activity: 57.5%. Smokers: 40.5% Data about musical practice - Years of practice: 6.5 +/- 5.5. Daily practice: 2.5 +/- 1.5 hours with 3.5 +/- 2 rest periods of 16.5 +/- 15 minutes. Weekly practice: 5 +/- 2 days. Data about medical problems - Hear loss 34%; respiratory difficulties: 19.5%; wound of lips muscles: 5%; gums and tongue lesions: 7.8%; myospasms of the cheeks and lips: 34.5%; dental problems: 30.7%; temporo-mandibular disorders (TMD): 22.5%. There is a high association between risk factors and pathology. Risks related to the instrument's use : hear loss (p = 0.001), traumas to lips muscles (p = 0.065), myospasms (p = 0.064), TMD (p = 0.000). Other factors: physical activity is beneficial; smoking is harmful (breathing difficulties, spasms, headaches). Factors influencing the different problems: age (31 +/- 7 years); years of practice (9 +/- 6); hours of practice per day (2 +/- 1.5); days of practice per week (4.5 +/- 2.5). CONCLUSION Wind instruments are related to problems of mouth, facial muscles and hearing. This may lead musicians to stop their activities or to irreversible professional disabilities. A medical follow-up during the musicians training is needed to prevent these problems.

Abstract
OBJECTIVE To evaluate the effect of distraction osteogenesis for severe micrognathia by comparing the pre- and post-operative profile and mentolabial relationship. METHODS 16 cases underwent temporal-mandibular joint plasty and temporal fasciomuscular flap transfer. The mandibular distraction began at the 5th postoperative day at a rate of 0.8 mm a day, two times a day. Bony and soft tissue cephalometry were performed before and after operation. T-test was used to study the change after distraction osteogenesis. RESULTS There were significant differences in facial convexity, lower facial height, lower lip length, inter-labial distance, the ratio of lip to mental, the distance from lip to esthetic plane, the depth of mentolabial crease and the thickness of mental soft tissue. CONCLUSIONS Mandibular distraction osteogenesis can markedly improve the soft tissue profile of the middle and lower face for severe micrognathia.

Abstract
OBJECTIVE To investigate the reconstruction of wide vermilion and orbicularis oris muscle defect with satisfactory outcome of aesthetics, sensation, and function. METHODS The buccal musculomucosal flap based on the anterior buccal branches of the facial artery was used to reconstruct wide defect of vermilion and orbicularis oris muscle on upper or lower lip. RESULTS 7 patients were treated. 5 cases had no postoperative complication. Partial mucosal necrosis on the tip of the flaps happened in 2 cases, but the underlying muscle survived and was re-mucosalized spontaneously. No other complication was observed. The sensation of cold, heat and touch could be detected on the first postoperative day. Electromyographic and electron microscopic studies confirmed innervation of the muscle in the flap. CONCLUSIONS The buccal musculomucosal flap is a reliable reconstruction option for wide defect of vermilion and orbicularis oris muscle which can' t be reconstructed with conventional method. Satisfactory aesthetic and functional results can be achieved with the buccal musculomucosal flap.

Abstract
OBJECTIVES Non-syndromic cleft lip with or without cleft palate (CL/P) is a common, complex birth defect with a wide phenotypic spectrum. This review summarizes the evidence that subepithelial (occult) defects of the superior orbicularis oris (OO) muscle represent the mildest form of the lip portion of CL/P. EXPERIMENTAL DESIGN The rate of OO defects was assessed via ultrasound in non-CL/P relatives of individuals with CL/P and compared with controls. Descriptive histology of OO muscles from cadavers was carried out. BMP4 was sequenced in non-CL/P individuals with OO defects vs. controls. RESULTS 1) Non-CL/P relatives of individuals with overt CL/P have a significantly increased frequency of OO defects compared with controls with no family history of CL/P; 2) Preliminary histological studies of cadaver OO muscles show a pattern of disorganized muscle fibers in an individual with OO discontinuities as seen on ultrasound compared with another individual with no OO defect. That is, the defects seen on ultrasound appear to have an anatomical basis; 3) Sequencing BMP4 found a significant increase in potentially damaging mutations in individuals with OO defects vs. controls. CONCLUSIONS Taken together, these data provide significant support for the hypothesis that subepithelial OO muscle defects are a mild manifestation of the lip portion of the CL/P phenotype. Given that subepithelial OO muscle defects are relatively straightforward to identify via ultrasound, such defects show great promise for providing more accurate recurrence risk estimates to relatives in cleft families. Furthermore, inclusion of OO defects in the CL/P phenotypic spectrum should improve the power of genetic studies.

Abstract
PURPOSE Treatment of facial paralysis by muscular neurotization resulted in ectopic ossification in 1 of 134 cases in this department. That patient suffering from Moebius syndrome (MS) is presented. Reviewing the literature concerning MS, Hox genes and bone morphogenetic protein dysregulation, a pathogenesis of ossification in MS is suggested. PATIENT The MS patient exhibited a congenital facial nerve palsy, which was treated by muscular neurotization (Lexer-Rosenthal). Because of postoperative ossification of scarred areas, osteotomy of the processus muscularis and mobilization of the masseter muscle was performed. Nevertheless, further ossification occurred at the interface between the mandible and zygoma and in two masticatory muscles. So, the construction of a neoarthrosis became necessary. Three years later, the iatrogenic bone defect had reossified despite of an active opening therapy. CONCLUSIONS Ectopic ossification after muscular neurotization seems to be restricted to patients with MS and is triggered by trauma. Molecular pathogenesis: facial malformations in MS are caused by disturbances in embryonic patterning. Failure in the development of the second pharyngeal arch leads to a spatial BMP-4 dysregulation responsible for ossification after wounding of muscle fascia. Therefore, surgical rehabilitation of facial function by muscular neurotization is contra indicated in MS patients.

Abstract
AbstractBackground:The buccinator musculomucosal flap is an axial-pattern flap based on either the buccal or the facial artery. We present our experience with this flap and describe its surgical anatomy, the surgical techniques utilised to raise the flap and its clinical applications.Materials and methods:We retrospectively reviewed all patients who had had buccinator myomucosal flaps created at the Groote Schuur Hospital between 1999 and 2004. Patients were also recalled to assess flap sensation and to record reduction of mouth opening as a consequence of donor site scarring.Results:Of the 14 patients who had had a buccinator myomucosal flap created, there was one flap failure. Sensation was present in 71 per cent of flaps, and there was no trismus due to donor site scarring.Conclusions:The buccinator myomycosal flap is a dependable flap with good functional outcome and low morbidity.

Abstract
The facial musculature is part of a biocybernetic feedback system within the stomatognathic system, the continuity of which is disturbed by clefts of the lip, jaw, and palate (cheilognathopalatoschisis). This results in topographic, fine-structural and functional alterations of the facial musculature. In two heads with unilateral clefts and two heads with bilateral clefts, the facial musculature was dissected and the M. orbicularis oris macroscopically and topographically examined. We found changes in the attachment of the M. orbicularis oris. The modiolus, which is coresponsible for the proper topographic relation of the M. obicularis oris to the other facial muscles, was unchanged. Further, we examined the vascular system of the muscle, which likewise adapts to the altered situation. Lip/jaw/palatal clefts result in anatomically functional and fine-structural alterations of the M. orbicularis oris, while the rest of the facial musculature remains unchanged.

Abstract
In short-term irreversible paralysis caused by facial nerve problems the aim is to re-innervate the paralysed facial musculature. Whenever a paralysis remains untreated for longer than 12-18 months successful re-innervation is unlikely. In longer-term paralysis the symmetry of the face at rest can be restored by a static procedure, a skin resection or a fascial suspension for example. Restoration of movement in the paralysed side of the face is possible by means of a dynamic procedure. For many years the temporal muscle and the masseter muscle have been used to improve the position of the mouth and closure of the eye. Spontaneous laughter can again be made possible by using a muscle from elsewhere in the body (e.g. the gracilis or possibly pectoralis minor) and attaching it to the nerve supply of the opposite side of the face.

Abstract
Involvement of P2X1 and P2X2 purinergic receptors in motoneuron response to injury was investigated with Western blotting and immunohistochemistry and correlated with motoneuron loss, Bcl-2 expression, nitric oxide synthase induction and glial activation. P2X1 was highly induced in rat facial motoneurons after nerve resection, which causes slowly occurring neurodegeneration. P2X1 induction was lower and less persistent after nerve crush, permissive for fiber regeneration. P2X2 expression was found in nuclei of rat facial motoneurons, with nuclear export in the cytoplasm after nerve resection. P2X1 induction in axotomized facial motoneurons was impaired in superoxide dismutase (SOD)1-G93A-mutant mice, a model of motoneuron disease. The data in rats point to a correlation of P2X1 induction with motoneuron degeneration, which also involves P2X2 intracellular changes, rather than with axon regeneration effort. The data in mice show that the SOD1 mutation interferes with injury-elicited P2X1 induction, suggesting alterations of ATP release from mutant motoneurons after damage.

Abstract
Nowadays, surgical interventions must treat with care the aesthetic impact on the patient, even when a malignant pathology or an patient's advanced age could give the aesthetic issue lower priority. The cranio-facial area is probably the most important anatomical region with regard to the harmony of the human body. Consequently, a step-by-step procedure, applicable regardless of the site and the nature of the lesion, is advisable to minimize the aesthetic impact. We prospectively analyzed 65 patients during a period of 2 years. At 1-year follow-up, all patients were invited to undergo a 3D-multislice CT and to complete a questionnaire with a subjective rating scale about aesthetic impact. The 3D-multislice CT scan didn't show dislocations, depressions or gaps of the bone flap. Nevertheless, five patients complained of some degree of aesthetic injury, or reported a psychological suffering from the aesthetic consequences of surgery. As a control group, we retrospectively reviewed 223 patients. The authors describe their surgical protocol and discuss it in the light of the results of their series.

Abstract
The demand for aging face surgery has increased dramatically over the past few decades, and it is likely that it will continue to flourish as the segment of our population over 65 years of age continues to grow. Facelift surgery is the cornerstone of aging face surgery. It is a procedure that has evolved over the years and has been designed to restore a youthful look to the lower face and neck. There are several different approaches available for the management of the aging face, each of which may be best suited to certain patient characteristics. It is essential that all approaches be understood to provide the most aesthetically pleasing surgical results to every patient.

Abstract
INTRODUCTION Particular importance is attached to lip repair cleft surgery, as numerous functional and aesthetic aspects have to be taken into account simultaneously. Spatial assessment of function and depiction of dynamic deviations is reasonable for describing surgical outcome in addition to long standing static analysis. This study aimed at 3D analysis of the oral area after reconstruction in patients with unilateral cleft lip, alveolus and palate. PATIENTS AND METHODS Twelve patients with unilateral cleft lip, alveolus and palate who underwent surgery according to Tennison-Randall were enrolled in this study. Soft tissue dynamics was analysed during passive stretching and active contraction of the lips, and photogrammetry was used for comparing relative changes of length and displacement vectors. The spatial coordinates of surgically significant and reproducible landmarks along the red-white lip junction were analyzed. RESULTS Static analysis of the lips revealed a good result with far-reaching symmetry in all cases. Regarding dynamic behaviour, two groups could be distinguished showing clear differences of passive distension and contraction behaviour. CONCLUSION Despite nominally identical surgical techniques and comparable static-morphological outcomes, dynamic analysis revealed differences pointing to a need for optimization.

Abstract
UNLABELLED Chronic progressive external ophthalmoplegia (CPEO) is a neuromyopathic disorder characterized by progressive weakness of the extraocular and levator muscles, which causes blepharoptosis and impairment of ocular motility. Because of the risk of worsening of lagophthalmos and exposure keratitis due to an associated poor Bell phenomenon or weak orbicularis function, surgical treatment of the blepharoptosis caused by CPEO is problematic. We present our experience with a case of blepharoptosis in CPEO. CASE A 61-year-old woman presented with slowly progressive bilateral blepharoptosis. A muscle biopsy of the rectus femoris revealed mitochondrial abnormalities, which satisfied the definition of the diagnosis of CPEO as mitochondrial encephalomyopathy. The lid opening was 2 mm, with maximal frontalis contraction, the levator function was zero, and the eyeball movement was severely limited. The blow movement was about 6 mm. Combination of modest blepharoplasty and frontalis suspension using a monofilament suture was performed. The postoperative result was satisfactory, and the patient's quality of life was markedly improved.

Abstract
Oral submucous fibrosis (OSF) is a common pre-malignant condition of the mouth in arecanut chewers in Indian subcontinent. It is characterized by restriction in opening of the mouth, tongue protrusion, and cheek flexibility. Reports of muscle changes in OSF, using light microscopy are few. Incisional biopsy sections of thirty OSF patients were stained with Masson's Trichrome stain, to study the fibrosis involving the muscle. Wide spectrum of changes were observed where fibrosis was being evident sub-epithelially, not extending in to the muscle to cases where only a few remnants of muscle fibers were seen and the missing muscle bundle area being replaced by fibrous tissue. The probable mechanism by which these changes occur is discussed.

Abstract
A proportion of patients with myasthenia gravis (MG) without acetylcholine receptor (AChR) antibodies have antibodies to muscle-specific kinase (MuSK). MG with MuSK antibodies (MuSK-MG) is often associated with persistent bulbar involvement, including marked facial weakness and tongue muscle wasting. The extent of muscle wasting in MuSK-MG, and whether it is also found in the few acetylcholine receptor (AChR-MG) patients who have persistent bulbar involvement, is not clear. We studied 12 MuSK-MG patients and recruited 14 AChR-MG patients matched broadly for age, sex ratio, duration of disease and degree of ocular, bulbar and facial weakness. We used coronal and sagittal T1-weighted (T1W) and T2-weighted (T2W) magnetic resonance imaging (MRI) to assess muscle wasting in facial and tongue muscles. Hyperintense signal on T1W MRI and comparison of axial T1W sequences with cUTE sequences were used to assess fibrous/fatty tissue in the tongue. We compared the results with those of four patients with myotonic dystrophy and 12 healthy individuals. We correlated the changes with clinical and treatment histories, and established a new ocular-bulbar-facial-respiratory (OBFR) score. At the time of study, none of the clinical measures, including the OBFR score, differed between the two MG groups. MRI demonstrated thinning of the buccinator, orbicularis oris (O.oris) and orbicularis oculi (O.oculi) muscles in MuSK-MG patients compared with healthy controls, whereas thinning of these muscles was not significant in AChR-MG. Tongue areas with T1W high signal were increased in MuSK-MG patients and the intensity of the signal on axial T1W sequences was greater in MuSK-MG than in controls. To look for possible correlations between imaging and clinical findings, we pooled results from all MG patients. The duration of treatment with prednisolone at >40 mg on alternate days (AD) correlated positively with the percentage of tongue area with high signal (P = 0.006) and negatively with MRI measurements of individual muscles and with the mean muscle dimensions (P = 0.001). The new OBFR score correlated positively with current Myasthenia Gravis Foundation of America grades and with the percentage of high signal (P = 0.004) and negatively with the mean muscle dimensions (P < 0.001). The results show that bulbar and facial muscle weakness and wasting are associated with significant muscle atrophy and fatty replacement in MuSK-MG, which was not found in the AChR-MG patients. MuSK antibodies per se may predispose to muscle thinning, but the difficulties in obtaining clinical remission under steroid therapy in some patients, resulting in long duration of treatment with higher doses (>40 mg AD), may be an additional factor.
