[The MASK lift]. / Le MASK lift.

The MASK lift or subperiosteal lift of the upper and middle thirds of the face is a procedure that can be performed alone for aesthetic purposes, but can also be combined with reconstructive surgery of this region to improve the result. This procedure will enable the overall result to be enhanced in the management of complex pathologies. The aim of this article is to present the MASK lift surgical technique in detail, to explain its indications and to show that this surgical technique still has a place in our practice.

Etiologies, periocular manifestations and surgeries for congenital and childhood acquired facial nerve palsy.

AIM: To report periocular surgeries performed for patients with congenital and childhood acquired facial nerve palsy (FNP). METHODS: A retrospective case series of pediatric patients who presented with FNP over the last 34 years, was conducted at two tertiary eye hospitals in Riyadh. Data were collected from electronic charts, hospital records and external photos. Main outcome measures were visual acuity, lagophthalmos, eyelid abnormalities, Bell's phenomena, exposure keratopathy, and corneal scar; in these cases, periocular surgeries were required. RESULTS: Among the 90 recruited subjects; the mean age of onset was 4.8±5.4 years old (range, 0.01 to 17.76 years). Traumatic and congenital causes of FNP were the most common, representing over 80% of the cases. Seventy-one patients developed lagophthalmos, 26 with severe exposure that resulted in scarring. Thirty-six (40%) cases had associated strabismus. Lower lid retraction was the most common eyelid abnormality noted in 23 cases, followed by entropion in 16 and ectropion in 6 cases. Temporary tarsorrhaphy was performed in three patients (3.3%), while 18 patients (20%) needed permanent tarsorrhaphy. Gold weight implants were placed in 17 patients (18.9%). Lower lid retraction repair was performed in twelve patients (13.3%). Five patients (5.6%) underwent lower eyelid entropion repair, and three patients (3.3%) underwent lower eyelid ectropion repair. CONCLUSIONS: Lagophthalmos is the most common finding in children presenting with FNP and needs to be managed early to prevent permanent visual loss. Compared to adults, children may present with a different spectrum of eyelid abnormalities, with lower lid retraction and entropion being the most common eyelid malpositions.

[Buccinator muscle: A new target for botulinum toxin injections in the treatment of facial paralysis sequelae]. / Le muscle buccinateur : une nouvelle cible pour les injections de toxine botulique dans le traitement des séquelles de paralysie faciale.

AIM OF THE STUDY: Facial paralysis can cause aesthetic and functional sequelae such as spasms and synkinesis. Botulinum toxin injection is one of the key treatments for these sequelae. Its use is widely reported in the literature for many muscles of the face but little for the buccinator muscle. However, its hyperactivity can be disabling, generating chewing and smile disorders in particular. The aim of this prospective study is to report the effects of botulinum toxin using a questionnaire specifically for the buccinator muscle. PATIENTS AND METHODS: The study was conducted on 13 patients. The facial paralysis was of various origins. The questionnaire consisted of 10 questions each assessing a facial mimic involving the buccinator muscle. The rating scale ranged from -10 (major deterioration) to 10 (major improvement) for each question. The evaluation was done at 1 and 4 months after the injection. We found an improvement for all the mimics and gestures evaluated (0 to 7.38 at 1 month and 0.15 to 6.62 at 4 months). This improvement was greater at 1 month than at 4 months. Few side effects were reported. CONCLUSION: Botulinum toxin injections are an effective, safe therapeutic solution for the treatment of the facial paralysis sequelae of the buccinator muscle through a new specific questionnaire. Subsequently, it would be interesting to carry out an evaluation on a larger population and to compare it with other recognized scores in facial paralysis.

[Stabilization and reanimation of the lower lip in facial palsy. Retrospective study about 66 patients and literature review. Proposition of a decision algorithm]. / Stabilisation et réanimation de la lèvre inférieure paralysée. Étude rétrospective de 66 cas et revue de la littérature. Proposition d'un algorithme décisionnel.

Several techniques for the stabilization and the reanimation of the paralyzed lower lip have been proposed, sometimes combined but the authors are rather vague. Thanks to our cases and a literature review, we suggest an algorithm. Sixty-six patients haven been reviewed. The static and dynamic clinical evaluation have been done thanks to the study of the medical files, photographs and videos samples. The different techniques we have used were: (a) botulinum toxin in the contralateral depressor labii inferioris (DLI) (n=66), contralateral DLI myectomy (n=1); (b) a strip of fascia lata (n=16) either combined with a lengthening temporalis myoplasty (MAT) (n=10) or only realizing a passive suspension thanks to one vector (n=4), or a passive suspension with two strips (n=2); (c) digastric muscle transfer (n=4). When the elevator muscles are sounds, botulin toxin (± myectomy) is proposed if the lower lip is not inverted. Otherwise, a suspension thanks to a digastric muscle transfer or a passive suspension with a horizontal and a vertical strips are recommended. If the elevator muscles are no more operational, a MAT with a passive suspension with one vector is considerated and if the lower lip is inverted, a digastric muscle transfer with a fascia lata strip or a MAT with two strips is proposed. This algorithm submission allows to refine the treatment of the stabilization and the reanimation of the lower lip.

[Synkinesis in facial palsy: What do we know about the physiopathology?] / Syncinésies dans la paralysie faciale : que savons-nous de la physiopathologie ?

INTRODUCTION: Synkinesis is a disabling sequelae of facial palsy, which worsens facial asymmetry and diminishes the patients' quality of life. Their physiopathology is partially known, but cannot explain all the synkinesis. MATERIAL AND METHODS: We report a literature review of the state of the art concerning the knowledge on synkinesis physiopathology, as well as their management. RESULTS: It is accepted that the physiopathological mechanism of synkinesis is mixed. The phenomena of cerebral plasticity, aberrant nerve regrowth, hyperexcitability of the facial nerve nucleus and ephaptic nerve transmission, have been observed. We propose a new physiopathological hypothesis: synkinesis could be the consequence of latent circuits activation, preexisting in the healthy subject. We could propose three potential latent circuits: physiological synergistic contractions, adjacent motor units recruitment, and reactivation of remote latent circuits for function compensation. The treatment options are multiple, dominated by chemodenervation, whose effectiveness is undeniable. Rehabilitation has also proven its effectiveness, particularly with feedback techniques. Finally, surgery helps with these options. However, the indications of the different treatments remain to be codified. CONCLUSION: The validation of our physiopathological hypothesis would allow a better understanding and a better screening of synkinesis, in order to propose a more adapted treatment.

[Hemifacial spasm. Etiology and management]. / Spasmes hémifaciaux. Étiologies et conduite à tenir.

INTRODUCTION: Hemifacial spasm (HFS) is an involuntary contracture of the facial muscles innervated by the ipsilateral facial nerve. We studied the etiology of these HFS. MATERIALS AND METHODS: This retrospective study included 233 patients with HFS who came to the ophthalmologist for quarterly botulinum neurotoxin A injection. Of these, we analyzed the 198 patients for whom MRI scans were performed. We recorded patient clinical data and clarified the etiology of their HFS. RESULTS: The 198 patients (62.6% women) had a mean age of 55.7±14years. An etiology was found in 52.5% of cases. In 34.5% of HFS, MRI revealed vascular compression where the facial nerve emerged from the brainstem. We specify the arteries involved. Brain tumors accounted for 1.5% of cases. MRI was normal in 64.5% of cases. In these secondary cases of HFS, we found 8.5% peripheral facial palsy, 4% post-traumatic HFS and 4% secondary to an eye injury. Stress was found in 17% of patients. DISCUSSION AND CONCLUSION: This study illustrates the need for MRI with attention to the posterior fossa in the work-up of HFS in order to identify primary HFS associated with vascular compression of the facial nerve and to rule out a rare but serious posterior fossa tumor. The treatment of HFS is based on quarterly injections of botulinum neurotoxin/A (NTBo/A), the three brands of which have market approval. The injection pattern and frequency is customized according to the results. In cases of insufficient response to injections of NTBo/A, neurosurgical microvascular decompression may be considered for cases of primary HFS.

[Sequelae in bell's palsy: Prognostic factors for recovery]. / Facteurs prédictifs des séquelles de paralysie faciale idiopathique : suivi longitudinal.

OBJECTIVES: Facial palsy can be assessed using objective and subjective tools. The main purpose of this work was to use these tools to determine at 12 months the percentage of patients with sequelae and to specify the type of sequelae. MATERIAL AND METHODS: Twenty-three patients with facial palsy were followed in this prospective and longitudinal study. They have been evaluated every 3 months during a year with the House and Brackmann grading scale and the Sunnybrook Facial Grading System. At 12 months, group A was composed of patients with complete recovery and group B, patients with sequelae. RESULTS: At 3 months, in patients of group B, the House-Brackmann grading scale (P=0.0134), the Sunnybrook Facial Grading System global score (P=0.0283) and dynamic score (P=0.0148) were lower than group A. Moreover, the movement "brow lift" (P=0.0181) seems to be relevant to predict follow-up. Synkinesis on "brow lift" (P=0.0270) and the treatment delay (P=0.0384) increased for group B. Sex, age, paralyzed side and recurrence of facial palsy had no influence. CONCLUSION: Objective and subjective tools determine thresholds and predictive scores of recovery with sequelae at 1 year. Nevertheless, it is relevant to assess clinically specific facial movements, such as "brow lift", to specify a recovery potential and to predict sequelae a year after the onset of facial palsy. As the treatment delay influences recovery, drug treatment should be recommended as early as possible.

[Association of borderline tuberculoid leprosy and tuberculosis: A case report and review of the literature]. / Association d'une lèpre borderline tuberculoïde et d'une tuberculose : un cas et revue de la littérature.

INTRODUCTION: In metropolitan France, nearly 20 new cases of leprosy are diagnosed each year. The incidence of tuberculosis in France is 8/100,000 inhabitants and there are very few accounts of association of these two mycobacteria. Herein we report a case of co-infection with borderline tuberculoid (BT) leprosy and disseminated tuberculosis diagnosed in metropolitan France. PATIENTS AND METHODS: A male subject presented with diffuse painless infiltrated erythematous plaques. The biopsy revealed perisudoral and perineural lymphohistiocytic epithelioid cell granuloma as well as acid-alcohol-fast bacilli on Ziehl staining. PCR was positive for Mycobacterium leprae, confirming the diagnosis of leprosy in the BT form. The staging examination revealed predominantly lymphocytic left pleural effusion, right-central necrotic adenopathy without histological granuloma, negative screening for BK, a positive QuantiFERON-TB™ test, and a positive intradermal tuberculin reaction. The clinical and radiological results militated in favour of disseminated tuberculosis. Combined therapy (rifampicin, isoniazid, ethambutol and pyrazinamide) together with clofazimine resulted in regression of both cutaneous and extra-cutaneous lesions. This rare co-infection combines leprosy, often present for several years, and tuberculosis (usually pulmonary) of subsequent onset. The pathophysiological hypothesis is that of cross-immunity (with anti-TB immunity protecting against subsequent leprosy and vice versa), supported by the inverse correlation of the two levels of prevalence and by the protection afforded by tuberculosis vaccination. In most cases, treatment for TB and leprosy improves both diseases. Patients presenting leprosy should be screened for latent tuberculosis in order to avoid reactivation, particularly in cases where corticosteroid treatment is being given.

[Facial paralysis sequelae: Long term follow-up revision surgery, redo, continuing care]. / Séquelles de paralysie faciale : un suivi au long court reprises, retouches, poursuite de prise en charge.

Facial paralysis sequelae have an intense psycho-social impact which imposes an optimal care in the long run. The surgical challenges are numerous, and the therapeutic weapons are multiple. We propose an analysis of these treatments by the prism of their pitfalls and their limits. The complications of the main surgical procedures are described as well as the details of the rework necessary to cope with them or to quickly correct the defects. Moreover, the result limits are detailed with suggestions to improve them. Finally, we develop the necessary iterative treatments or new therapeutic proposals that are essential for the long-term care of these patients whose sequelae of facial paralysis evolve with time and aging. The surgery of facial paralysis is not unequivocal. It requires humility, patience and tenacity to support the patient throughout his life.

Does Type 2 Diabetes Mellitus Affect the Healing of Bell's Palsy in Adults?

OBJECTIVES: Bell's palsy (BP) is defined as an acute facial weakness of unknown cause. Many factors affecting the healing of BP have been identified; 1 factor commonly considered relevant is the presence of type 2 diabetes mellitus. Our aim was to investigate the effects of diabetes on the healing of BP. METHODS: Sixty patients with BP were followed up for 1 to 3 years and were divided into 2 groups, those with and those without type 2 diabetes. All were prescribed prednisone (initially 1 mg/kg per day, with a tapered dose reduction) and acyclovir (200 mg orally every 4 h, 5 times daily, for 5 days). Their recovery times were compared. RESULTS: The healing times of the patients with and without diabetes did not differ. CONCLUSIONS: Diabetes does not affect the severity, recovery rate from or healing of BP.

Facial reanimation surgery in Möbius syndrome: Experience from 76 cases from a tertiary referral hospital in Latin America.

INTRODUCTION: Möbius syndrome is defined as a combined congenital bilateral facial and abducens nerve palsies. The main goal of treatment is to provide facial reanimation by means of a dynamic surgical procedure. The microneurovascular transfer of a free muscle transplant is the procedure of choice for facial animation in a child with facial paralysis. OBSERVATION: Between January 2008 and January 2017, 124 patients with the syndrome have been approached at our institution. Distribution according to Möbius Syndrome classification presents as follows: Complete Möbius syndrome (n=88), Incomplete Möbius syndrome (n=28), Möbius-Like syndrome (n=8). Seventy-nine female and 45 male patients. Sixty-one percent have undergone a microsurgical procedure (n=76), in all of them, a free gracilis flap transfer was performed. DISCUSSION: Our proposed treatment protocol for complete Möbius syndrome is determined by the available donor nerves. We prefer to use the masseteric nerve as first choice, however, if this nerve is not available, then our second choice is the spinal accesory nerve. For this purpose, all patients have an electromyography performed preoperatively. Overall, dynamic facial reanimation obtained through the microvascular transfer of the gracilis muscle have proved to improve notoriously oral comissure excursion and speech intelligibility. CONCLUSION: The free gracilis flap transfer is a reproducible procedure for patients with Möbius syndrome. It is of utmost importance to select the best motor nerve possible, based on an individualized preoperative clinical and electromyographic evaluation. To our best knowledge, this is the largest series of patients with Möbius syndrome globally, treated at a single-institution.

[Electromyographic assessment of the temporalis muscle prior to a lengthening myoplasty in patients with Moebius syndrome]. / Étude électromyographique du muscle temporalis avant une myoplastie d'allongement dans le syndrome de Moebius.

BACKGROUND/OBJECTIVES: Temporalis muscle lengthening myoplasty improves tightening of the lips and rehabilitates smile for patients with congenital facial palsies. Because Moebius syndrome is heterogeneous, a careful evaluation is mandatory before deciding to perform myoplasty. This series shows the role of electromyography for investigating temporalis muscle and trigeminal nerve motor functions. METHODS: We conducted a retrospective study of 18 patients with no upward movements of the labial commissure and absent or unsightly smile. Electromyography was used to study the temporalis muscle bilaterally. Analysis focused on the recruitment pattern of voluntary contraction and electrical silence or activity at rest. Traces were classified as normal, neurogenic, or low-amplitude. Functional outcomes of myoplasty were evaluated by measuring the upward movement of the commissure (mm), and qualified as high (≥10), medium (>5), or little (≤5). RESULTS: Surgery was cancelled for 5 patients with abnormal electromyographic signs, neurogenic (2) or low-amplitude (3). Myoplasty was performed in 7 patients (age: 8-17 years), unilaterally (3) or bilaterally (4). Preoperative electromyogram was normal (3), or showed moderate neurogenic (2) or low-amplitude (2) changes. Follow-up period after surgery was from 2 to 12 years; functional outcomes were high (5), medium (1), or little (1). CONCLUSION: Electromyographic study of the temporalis can detect muscle denervation or atrophy, or dyspraxia, and guide decision to encourage or discourage performing myoplasty, or enhance rehabilitation programme and make the patient aware of possibly modest outcome.

[Peripheral facial paralysis revealing HIV infection in black African populations]. / Paralysie faciale peripherique revelatrice d'une infection par le VIH chez le noir Africain.

INTRODUCTION: Peripheral facial paralysis (PFP), a frequent complication during infection with the human immunodeficiency virus (HIV), is a major cause of morbidity for these patients. The aim of this study was to show the place of unilateral PFP in the discovery of HIV infection in tropical areas. MATERIAL AND METHODS: This is a descriptive cross-sectional study with prospective data collection over a 12-month period, in the ENT departments of the Ignace Deen National Hospital and Neurology Hospital of the Sino-Guinean Friendship Hospital (CHU de Conakry). RESULTS: Of the 2517 patients received during the study period, 64 had PFP, a prevalence of 2.54%. HIV serology was performed in 56 patients, 24 of whom had a positive serological reaction, a prevalence of 42.86%. The young adult population was the most exposed, with an average age of 34.5 years. There were 9 men and 15 women, or a sex ratio of 0.6. In 70.83% of cases, the consultation period occurred between the 1st and 3rd week. Unilateral facial asymmetry and persistent opening of the palpebral fissure were the main clinical signs. A total of 75% of our patients were infected with HIV1. CD4 levels ranged from 175 to 400/mm3. All our patients had received PFP and HIV treatments. The evolution was marked by a complete recovery with no sequelae of PFP in 62.5% of cases. CONCLUSION: The occurrence of isolated PFP in apparently healthy adults should suggest seroconversion to HIV. The prognosis of these PFPs is often good despite the delay in diagnosis.

INTRODUCTION: La paralysie faciale périphérique (PFP), complication fréquente au cours de l'infection par le virus de l'immunodéficience humaine (VIH), constitue une cause importante de morbidité chez ces patients. Le but de cette étude était de montrer la place de la PFP unilatérale dans la découverte de l'infection par le VIH en zone tropicale. MATÉRIEL ET MÉTHODES: Il s'agit d'une étude transversale descriptive avec collecte des données prospective, sur une période de 12 mois, réalisée dans les services d'ORL de l'Hôpital National Ignace Deen et de Neurologie de l'hôpital de l'amitié Sino-Guinéenne (CHU de Conakry). RÉSULTATS: Sur les 2517 patients reçus en consultation durant notre période d'étude, 64 présentaient une PFP soit une prévalence de 2,54%. La sérologie VIH avait été réalisée chez 56 patients, dont 24 avaient eu une réaction sérologique positive, soit une prévalence 42,86 %. La population adulte jeune était la plus exposée, avec un âge moyen de 34,5 ans. Il s'agissait de 9 hommes et 15 femmes, soit un sex-ratio de 0,6. Le délai de consultation était, dans 70,83% des cas, situé entre la 1ère et 3ème semaine. L'asymétrie faciale unilatérale et la persistance d'ouverture de la fente palpébrale étaient les principaux signes cliniques. Au total 75 % de nos patients étaient porteurs du VIH1. Le taux de CD4 variait entre 175 et 400/mm3. Tous nos patients avaient bénéficié d'un traitement de la PFP et du VIH. L'évolution avait été marquée par la récupération totale et sans séquelle la PFP dans 62,5% des cas. CONCLUSION: La survenue d'une PFP isolée chez l'adulte apparemment en bonne santé, doit faire évoquer une séroconversion au VIH. Le pronostic de ces PFP est souvent bon malgré le retard diagnostic.

[Facial palsy in children]. / Paralysie faciale chez l'enfant.

Facial palsy (FP) in children is congenital or acquired. When present at birth (congenital), etiologies are mostly traumatic and rarely developmental. Acquired FP needs investigation. Research on the etiology helps to determine prognostic and treatment. At most times, no specific cause is found. Treatment of idiopathic FP consists of early oral corticosteroid therapy and ocular protection. Treating the sequelae is essential and the physician has to consider the dynamic balance of both sides of the face. Dynamic rehabilitation should mainly concern the inferior facial third. We recommend the lengthening temporalis myoplasty (LTM). This relevant technique ensures replicable and reliable results with a harmonious smile. Facial dynamic rehabilitation after surgical procedure (muscle tranfer or free muscle flap) must be directed toward control of voluntary movement, to move from a mandibular smile to a spontaneous and voluntary smile, thanks to brain plasticity. Furthermore, botulinum toxin is well tolerated and remains a great tool to treat a child who can support injections.

[Perception of asymmetry smile: Attempt to evaluation through Photoshop]. / Perception de l'asymétrie du sourire : tentative d'évaluation grâce à Photoshop.

UNLABELLED: In the labial palliative surgery of facial paralysis, it can persist asymmetry smile. OBJECTIVE: Evaluate the impact of an augmentation or reduction of the commissural course on the perception of a smile anomaly, and determine from which asymmetry threshold, the smile is estimated unsightly. MATERIAL AND METHOD: We took a picture of two people with a smile not forced; including one with a "cuspid smile", and the another one with a "Mona Lisa" smile. The pictures obtained were modified by the Photoshop software, to simulate an asymmetry labial smile. The changes were related to the move of the left labial commissure, the left nasolabial furrow, and the left cheek using under-correction and overcorrection, every 4 mm. Three pictures with under-correction and four pictures with over-correction were obtained. These smiles were shown to three groups of five people, which included doctors in smile specialties, doctors in other specialties, and non-doctors. Participants were then asked to indicate on which of the pictures, the smile seemed abnormal. RESULTS: Between -8 mm under-correction, and +8 mm over-correction, the asymmetry of the commissural course does not hinder the perception of smile. CONCLUSION: In the labial palliative surgery of facial paralysis, in the case of persistent asymmetry, there is a tolerance in the perception of "normality" of smile concerning the amplitude of the commissural course going up to 8 mm of asymmetric with under-correction or over-correction.

Facial reanimation by muscle-nerve neurotization after facial nerve sacrifice. Case report.

INTRODUCTION: Recovering a certain degree of mimicry after sacrifice of the facial nerve is a clinically recognized finding. The authors report a case of hemifacial reanimation suggesting a phenomenon of neurotization from muscle-to-nerve. CLINICAL CASE: A woman benefited from a parotidectomy with sacrifice of the left facial nerve indicated for recurrent tumor in the gland. The distal branches of the facial nerve, isolated at the time of resection, were buried in the masseter muscle underneath. The patient recovered a voluntary hémifacial motricity. The electromyographic analysis of the motor activity of the zygomaticus major before and after block of the masseter nerve showed a dependence between mimic muscles and the masseter muscle. DISCUSSION: Several hypotheses have been advanced to explain the spontaneous reanimation of facial paralysis. The clinical case makes it possible to argue in favor of muscle-to-nerve neurotization from masseter muscle to distal branches of the facial nerve. It illustrates the quality of motricity that can be obtained thanks to this procedure. CONCLUSION: The authors describe a simple implantation technique of distal branches of the facial nerve in the masseter muscle during a radical parotidectomy with facial nerve sacrifice and recovery of resting tone but also a quality voluntary mimicry.

Long-term sequelae treatment of peripheral facial paralysis with botulinum toxin type A: Repartition and kinetics of doses used.

STUDY OBJECTIVES: Botulinum toxin is a key therapeutic tool in the comprehensive treatment of peripheral facial paralysis. It fights spasms, synkinesis and overactivity of the different skin muscles responsible of facial expressions. Even though injection techniques as well as target muscles have been well identified, doses used remain quite imprecise and often not detailed muscle by muscle, further more dosage progression has not been monitored over time. Our retrospective study is the first one to refine the repartition of botulinum toxin doses on each of the relevant skin muscles and assess dosage kinetics. PATIENTS AND METHODS: Thirty patients were included since 2008 with a mean follow-up of 2.3years. Each patient had at least 3 injections, with a delay of 4 to 6months between each injection. RESULTS: Mean doses are indicated for each muscle injected on the paralyzed and healthy sides. Dose kinetics suggests an initial dosage increase after the first injection followed by a decrease over time. No treatment resistance was observed. CONCLUSION: Our study represents a didactic help in using botulinum toxin for sequelae of peripheral facial paralysis by providing more details on the effective mean doses for each muscle and their progression over time.

[Lengthening temporalis myoplasty: Technical refinements]. / La myoplastie d'allongement du muscle temporal: raffinements techniques.

First described by Labbé in 1997, the lengthening temporalis myoplasty (LTM) ensures the transfer of the entire temporal muscle from the coronoid process to the upper half of the lip without interposition of aponeurotic tissue. Thanks to brain plasticity, the temporal muscle is able to change its function because it is entirely mobilized towards another effector: the labial commissure. After 6 months of speech rehabilitation, the muscle loses its chewing function and it acquires its new smiling function. We describe as far as possible all the technical points to guide surgeons who would like to perform this powerful surgical procedure. We show the coronoid process approaches both through an upper temporal fossa approach and a lower nasolabial fold approach. Rehabilitation starts 3 weeks after the surgery following a standardized protocol to move from a mandibular smile to a voluntary smile, and then a spontaneous smile in 3 steps. The LTM is the main part of a one-stage global treatment of the paralyzed face. It constitutes a dynamic palliative treatment usually started at the sequelae stage, 18 months after the outcome of a peripheral facial paralysis. This one-stage procedure is a reproducible and relevant surgical technique in the difficult treatment of peripheral facial paralysis. An active muscle is transferred to reanimate the labial commissure and to recreate a mobile nasolabial fold.

[Facial palsy sequel and botulinum toxin]. / Séquelles de paralysie faciale et toxine botulique.

Medical treatment of facial paralysis sequel is an essential part of the overall management of this pathology. The use of botulinum toxin has revolutionized results in greatly improving facial symmetry. The toxin can be used either the healthy side of the face by treating the compensatory hyperactivity of non-paralyzed side of the face or the paralyzed side (in the spastic forms) to treat synkinesis and spasms of the face on the pathologic side. This treatment course will be complemented by the rest of the therapeutic, i.e. rehabilitation and surgical treatment.
