RĂ©Ă©ducation orthophonique post myoplastie dâallongement du temporal : une Ă©tude de trois patients
La myoplastie dâallongement du temporal est une chirurgie qui vise Ă restaurer le sourire chez les patients ayant une paralysie faciale pĂ©riphĂ©rique irrĂ©versible. Le muscle temporal est dĂ©tachĂ© dans sa partie haute et rattachĂ© Ă la commissure labiale. Ă la suite de la chirurgie, une rĂ©Ă©ducation orthophonique est nĂ©cessaire pour atteindre un sourire fonctionnel. Cette rĂ©Ă©ducation vise Ă automatiser le sourire pour le rendre spontanĂ©, ainsi quâĂ optimiser le sourire pour rendre le mouvement de la commissure opĂ©rĂ©e symĂ©trique Ă celui du cĂŽtĂ© sain. Parmi les moyens utilisĂ©s dans cette rĂ©Ă©ducation, un logiciel reproduisant lâhĂ©miface saine permet de crĂ©er un effet-miroir, en offrant un biofeedback visuel positif aux patients. Les objectifs de la prĂ©sente Ă©tude de cas multiples Ă©taient 1) de mesurer les effets de la rĂ©Ă©ducation orthophonique aprĂšs la myoplastie dâallongement du temporal et 2) de mesurer lâadhĂ©rence au traitement. Trois patients prĂ©sentant une paralysie faciale pĂ©riphĂ©rique droite secondaire Ă une rĂ©section de tumeur et ayant subi une myoplastie dâallongement du temporal ont Ă©tĂ© recrutĂ©s. Ces patients ont tous Ă©tĂ© Ă©valuĂ©s avant la chirurgie, ainsi quâavant et aprĂšs la rĂ©Ă©ducation, Ă lâaide de lâĂ©chelle Sunnybrook. Les rĂ©sultats ont confirmĂ© quâĂ la suite de la rĂ©Ă©ducation orthophonique, le sourire des trois patients avait progressĂ©.Compte tenu des rĂ©sultats prometteurs obtenus avec cette rĂ©Ă©ducation, il serait intĂ©ressant dâen valider lâefficacitĂ© sur un plus grand nombre de patients.Lengthening temporalis myoplasty is a surgical procedure to restore the smile in patients with irreversible facial nerve paralysis. The temporalis muscle is detached from its upper end and attached to the labial commissure. Following surgery, facial rehabilitation by speech-language pathologists is necessary to achieve a functional smile. More specifically, this rehabilitation aims to automate the smile to make it spontaneous, as well as to optimize the smile to make the movement of the commissure operated on symmetrical to that of the healthy side. Among the means used in
this rehabilitation, a software program reproducing the healthy hemiface allows for the creation of a âmirror effectâ by giving the patients positive visual biofeedback. The objectives of this multiple case study were (a) to measure the effects of facial rehabilitation after lengthening temporalis myoplasty and (b) to measure adherence to treatment. Three patients with right facial nerve paralysis secondary to tumour resection that had lengthening temporalis myoplasty were enrolled. These patients were all assessed before surgery, and before and after rehabilitation, using the Sunnybrook scale. The results confirmed that following facial rehabilitation, the smiles of the three patients had improved. Given the promising results obtained from this rehabilitation, it would be interesting to validate its effectiveness on a larger number of patients
Reconstruction of medium-size defects of the oral cavity: radial forearm free flap vs facial artery musculo-mucosal flap
Abstract Background The radial forearm free flap (RFFF) is the most commonly used flap for defects of the oral cavity. The facial artery musculomucosal (FAMM) is a safe and effective method to reconstruct medium sized defects of the oral cavity. No comparison exists between the FAMM flap and RFFF. Methods 1) Retrospective chart review from 2007 to 2016. 2) Cost difference analysis. Results Thirteen FAMM flap cases and 18 RFFF met inclusion criteria. The FAMM flap showed a tendency to lower rates of return to the operating room (pâ=â0.065) as well as lower rates of complications not requiring return to the OR with 1 complication in 1 patient as opposed to 10 patients with 15 complications (pâ=â0.008). Also, FAMM flap had shorter operative times compared to the RFFF group (7.2HR and 8.9 HR respectively, pâ=â0.002). The average operative room related costs for a FAMM flap were 6510 CAD vs 10,703 CAD for RFFF (pâ 0.05). Conclusion The FAMM flap can be used for reconstruction of medium-size defects of the oral cavity with functional outcomes similar to the RFFF while decreasing the associated costs and morbidity.

Quantification and visualization of aerosols in ear, nose, and throat exam and flexible laryngoscopy
OBJECTIVE: To measure and visualize aerosol generation during ear, nose, and throat (ENT) exam and flexible laryngoscopy, as safety recommendations are currently to defer routine and lowâpriority examinations. METHODS: Aerosols generated during ENT examination and flexible laryngoscopy were quantified by laser aerosol spectrometry and visualized live by highâspeed imaging during those procedures for three participants who were tested three times for each test. RESULTS: Routine ENT examination and flexible laryngoscopy produce aerosols at levels comparable to normal breathing and speech. CONCLUSION: During ENT examination and flexible laryngoscopy, the practitioner should wear a surgical mask and potentially contaminated surfaces should be cleaned after the procedure. For flexible laryngoscopy, it is recommended in addition that the patient wear a mask over the mouth in case the procedure induces a sneeze. The time during which the patient is unmasked should be minimized. In these settings, the risk to the practitioner is minimal unless the patient is sneezing or symptomatic. LEVEL OF EVIDENCE:
Free versus pedicled flaps for reconstruction of head and neck cancer defects: a systematic review
Abstract Objective The present review focuses on comparative studies of reconstruction with free flaps (FF) versus pedicled flaps (PF) after oncologic resection. Method A systematic review was developed in compliance with PRISMA guidelines and performed using the Pubmed, Medline, EMBASE, Amed and Biosis databases. Results A total of 30 articles were included. FF are associated with a longer operative time, a higher cost and a higher incidence of postoperative revisions compared to PF. FF are associated with a longer stay at the intensive care unit than the supraclavicular artery island flap (SCAIF) and with a more extended hospital stay compared to the submental island flap (SMIF). FF are associated with fewer infections and necrosis compared to the pectoralis major myocutaneous flap (PMMF). Conclusion The comparison of both type of flaps is limited by the inherent design of the studies included. In sum, FF seem superior to the PMMF for several outcomes. SMIF and SCAIF compare favorably to FF for some specific indications achieving similar outcomes at a lower cost
A pilot study on the Mirror Effect PLUS protocol : a standardized and adapted facial rehabilitation for acute Bellâs palsy
Combining early facial exercises with medication may help patients with acute Bellâs palsy
recover significantly faster and better than patients treated with medication alone. To date,
exercise therapy in acute Bellâs palsy consists mostly of transferring facial rehabilitation
techniques that were developed for chronic Bellâs palsy, despite the differences between
those stages. The aim of this pilot study was to estimate the efficacy of the Mirror Effect
PLUS Protocol, the first facial rehabilitation protocol specifically designed for acute Bellâs
palsy. Ten patients with acute moderate-to-severe, severe, and total Bellâs palsy were
recruited and assigned randomly to the Mirror Effect PLUS Protocol group or the control
group. Both groups received the recommended medications. In addition, patients in the
rehabilitation group performed exercises that were completed using a computer that
duplicated their healthy hemiface. Compared to controls, a greater number of patients
in the Mirror Effect PLUS Protocol group presented better facial symmetry and greater
satisfaction towards their facial function. There were no differences in recovery between
the rehabilitation and control groups; however, for the subset of patients with severe palsy,
the Mirror Effect PLUS Protocol improved and accelerated recovery. These preliminary
results support the hypothesis that the Mirror Effect PLUS Protocol enhances the recovery
of severe acute Bellâs palsy. However, replication of these results with larger samples
is necessary. Additionally, the interventionâs precise mechanisms of action need to be
investigated thoroughly to exclude the effect of spontaneous recoveryCombiner une rééducation orthophonique à la prise de médicaments pourrait favoriser un rétablissement plus rapide et
optimal des patients présentant une paralysie de Bell en phase aiguë, comparativement à la prise seule de médicaments.
Présentement, la rééducation qui est offerte aux patients présentant une paralysie de Bell en phase aiguë consiste
principalement en lâutilisation de techniques ayant Ă©tĂ© dĂ©veloppĂ©es pour les patients ayant une paralysie de Bell chronique,
et ce, malgrĂ© les diffĂ©rences entre ces stades de la pathologie. Lâobjectif de la prĂ©sente Ă©tude pilote Ă©tait dâĂ©valuer
lâefficacitĂ© du protocole Effet Miroir Plus, un premier protocole de rĂ©Ă©ducation orthophonique spĂ©cifiquement conçu
pour la paralysie de Bell en phase aiguĂ«. Dix patients prĂ©sentant une paralysie de Bell en phase aiguĂ« de degrĂ© «âmodĂ©rĂ© Ă
sĂ©vĂšreâ» ou «âsĂ©vĂšreâ», ou encore, pouvant ĂȘtre qualifiĂ©e de «âtotaleâ» ont Ă©tĂ© recrutĂ©s. Ceux-ci ont Ă©tĂ© divisĂ©s alĂ©atoirement
dans deux groupes : un groupe de patients à qui le protocole Effet Miroir Plus a été administré et un groupe contrÎle. Les
deux groupes ont pris les médicaments recommandés dans le traitement standard de la paralysie de Bell. Les patients du
groupe à qui une rééducation orthophonique a été offerte ont également effectué des exercices musculaires en utilisant
un ordinateur qui dupliquait leur hémiface saine. Lorsque comparés aux patients du groupe contrÎle, un plus grand nombre
de patients du groupe Effet Miroir présentaient une meilleure symétrie faciale et une plus grande satisfaction à l'égard de
leur fonction faciale. En termes de rĂ©tablissement, aucune diffĂ©rence nâa Ă©tĂ© notĂ©e entre les groupes, sauf pour le sousensemble de patients ayant une paralysie de degrĂ© «âsĂ©vĂšreâ». Dans ce cas prĂ©cis, le protocole Effet Miroir Plus a amĂ©liorĂ© et
accĂ©lĂ©rĂ© le rĂ©tablissement. Ces rĂ©sultats prĂ©liminaires soutiennent lâhypothĂšse que le protocole Effet Miroir Plus amĂ©liore
le rétablissement des patients ayant une paralysie de Bell en phase aiguë de degré « sévÚre ». Il sera toutefois nécessaire de
rĂ©pliquer ces rĂ©sultats avec des Ă©chantillons plus importants. Ajoutons quâil sera Ă©galement important dâinvestiguer de façon
approfondie les mĂ©canismes dâaction prĂ©cis de la rĂ©Ă©ducation orthophonique pour exclure lâhypothĂšse dâun rĂ©tablissement

Cubane Cu 4 I 4 (phosphine) 4 Complexes as New Coinitiator for Free Radical Photopolymerization: Towards Aromatic Amine-Free Systems
International audienceThe investigation of copper-iodide cubane derivatives as new co-initiators for the free radical polymerization (FRP) of acrylate monomers under mild irradiation conditions is described for the first time here. These tetranuclear Cu(I)-based complexes have general formula Cu4I4(phosphine)4, where phosphine is triphenylphosphine (Cu1) or diphenylphosphine (Cu2). In the presence of commercial Type II photoinitiators such as isopropylthioxanthone (ITX) or camphorquinone (CQ), this class of co-initiators achieves high final conversions of the reactive functional groups. Comparison between the aromatic amine, such as ethyldimethylaminobenzoate (EDB) used as benchmark hydrogen donor, and these copper-based co-initiators are made, which demonstrates that the latter can be considered as a valid, environmental-friendly, alternative to toxic aromatic amines. Markedly, photoluminescent materials can be generated thanks to the presence of cubanes linked to the polymer network
