The material and methods used included a comparative analysis of medical scientific articles produced with and without the use of ChatGPT. The results suggest that the use of ChatGPT can be a useful tool for scientists to increase the production of higher quality medical scientific articles, but it is important to note that AI cannot fully replace human authors. In conclusion, scientists should consider ChatGPT as an additional tool to produce higher quality medical scientific articles more quickly.

Case-report of an Abrikossoff tumor of the temporomandibular joint Rapport de cas d'une tumeur d'Abrikossoff de l'articulation temporo-mandibulaire.

Granular cell tumors are rare tumors with multiple localizations. The most common localizations are in the cervicofacial region in 45-65% of cases. The characterization of this tumor depends on its clinical and histopathological findings. A few cases have been reported describing more unusual localizations, such as in the juxta-axilla or in the gastrointestinal tract. In this article, we describe an original localization: the region of the temporomandibular joint. This case-report describes a clinical case that was managed in the Department of Maxillofacial and Oral Surgery of the Saint-Joseph Hospital. The tumoral lesions usually described for this anatomical location are usually bony or synovial lesions. Here, the clinical examination didn't correspond to any of those descriptions and the MRI also confirmed that this tumor characteristics weren't compatible with this kind of lesion.

[Sterilisation of patient specific surgical guide for dental implantology made in a hospital: Validation of a sterility test and structural deformation study]. / Stérilisation de guides d'implantologie imprimés sur mesure à l'hôpital : validation d'un essai de stérilité et étude de déformation.

Medical device made to measure by 3D printing are now emerging in hospital. In order to improve the precision of surgery and facilitate the treatment of complicated cases, patient specific surgical guides for dental implantology are made by stereolithography in our facial surgical unit. This new activity requires to ensure the safety of patients and health personnel by validating the various step of the manufacturing circuit. In this context, the goal of this work was to study the quality of autoclave sterilisation of the patient specific surgical guide made to measure in our hospital. A protocol of sterility test was designed and validated. Sterility of implantology guides 0, 7, 14 and 28 days after sterilisation was checked. The impact of the autoclave sterilisation on the medical device structure was evaluated by visual check and during surgeries. The sterility of the implantology guides up to 28 days after sterilisation was also validated. The protocol of sterility test executed can be extended to other hospitals interested in validating a sterility test. No deformation was observed by surgeons during the dental implant process. Future studies may be necessary to check the accurate impact of sterilisation on surgical guide structure.

Computer-assisted versus traditional technique in fibular free-flap mandibular reconstruction: A CT symmetry study.

OBJECTIVES: In the past few years, virtual planning has been increasingly used for mandibular reconstruction. The objective of our study was to evaluate and compare symmetry and the accuracy of morphologic reconstruction in patients undergoing mandibular reconstruction by fibular free flap between traditional freehand technique and computer-aided surgical cutting guides. MATERIAL AND METHODS: A single-center retrospective study included all cases of mandibular reconstruction using fibular free flap. In the three-dimensional (3D) group, virtual surgery planning with cut guides was used (Materialise ®), while the Control group underwent traditional freehand reconstruction. Morphometric comparisons were made to evaluate reconstruction accuracy between pre- and post-operative CT scans (mean deviations of 3 angles and 3 lengths). Mandible symmetry was calculated by comparing each angle and length in the affected and non-affected sides of the mandible. RESULTS: Thirty-three patients treated between January 2015 and June 2018 were included: 25 patients in the 3D group and 8 in the control group. The average number of mandibular segments was 2.16±0.55 in the 3D group and 1.75±1.16 in the control group (p=0.005). Mean deviations between pre- and post-operative values of the coronal mandibular angle (angle formed by the line through the two condyles and the ramus), mandibular body height and mandibular ramus length on the affected side were significantly lower in the 3D group than in the control group. Sagittal mandibular angle symmetry was better in the 3D group than, in the control group (ratios of affected over non-affected sides: 1.07±0.04 vs 1.12±0.1; p=0.034). CONCLUSION: Virtual surgical planning for fibula free-flap reconstruction helps to improve reconstruction accuracy and maintains a significantly greater symmetry than the traditional freehand technique, and should improve functional and esthetic outcome in mandibular reconstruction.

Implementation of a digital chain for the design and manufacture of implant-based surgical guides in a hospital setting.

The digital revolution has led to many recent developments in implantology that have considerably facilitated implant planning and the creation of surgical guides. The purpose of this article is to explain how we set up a digital workflow in a large city hospital and how we met the requirements of the European regulations on the production of custom-made devices in a medical establishment. The internal manufacture of a surgical guide complied with European regulation EU/2017/45 concerning medical devices. This regulation allowed the hospital to create these medical devices locally without CE marking. However, the hospital must be declared as a manufacturer of medical devices and comply with the general requirements in terms of safety and performance related to the manufacture and use of medical devices. In addition, hospitals are large structures involving many different actors. Each step of the digital workflow, which included both the patient course and the creation of the surgical guide, was thus adapted to European regulations by considering local constraints.

Groin reconstruction using a pedicled anterolateral thigh flap.

INTRODUCTION: This article describes an attractive approach to the reconstruction of the groin after loss of substance: the skin, subcutaneous tissue and fascia of the rectus abdominis and oblique muscles were reconstructed using an anterolateral thigh flap based on a proximal vascular pedicle. CLINICAL CASE REPORT: A 70-year-old female with a strangulated inguinal hernia that had been neglected for eight days presented initially with intestinal necrosis and necrotizing infection of the abdominal wall in the right groin. After debridement of necrotic tissue, reconstructive surgery was necessary. We opted for an anterolateral thigh flap based on a proximal vascular pedicle. DISCUSSION: In this case, there was a major loss of substance that included the rectus abdominis fascia below the level of the arcuate line. This situation required a fascial reconstruction of the abdominal wall; a defect of this size would typically require synthetic mesh for closure. The anterolateral thigh flap allowed us to avoid the use of foreign material by repairing the defect with a pedicle flap including fascia lata and the quadriceps aponeurosis. CONCLUSION: The use of an anterolateral thigh flap based on a proximal vascular pedicle seems to be a simple straightforward solution for reconstruction of the skin and fascia of the inguinal region.

[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.

[Management of oculo-palpebral consequences in facial paralysis]. / Prise en charge des atteintes orbito-palpébrales secondaires à une paralysie faciale.

Facial paralysis prognostic depends on eye lesion. In this pathology, lacrymal and palpebral functions will be modified: bad eye closure and leak of tears secretions. It can leads to corneal complications from keratitis to corneal abcedation and visual dysfonction. This chapter details different procedures and their indications to avoid this kind of complications.

[Bicortical reconstruction of a large calvarial bone defect with Hydroset® osteoconductive cement and titanium mesh. A preliminary study]. / Reconstitution bicorticale de grande taille de l'os calvarial par ciment ostéoconducteur Hydroset® associé à une grille en titane. Étude préliminaire.

INTRODUCTION: Bi-cortical calvarial bone loss is a very frequent issue for neurosurgery and craniofacial surgery. Several techniques can be used to reconstruct the skull, with variable difficulty and costs. The purpose of our study was to assess the use of Hydroset® osteoconductive cement for large size bicortical cranioplasties. MATERIALS AND METHODS: Three patients presented with extensive loss of calvarial bone bi-cortical substance (>25 cm(2)), between 2010 and 2012. The 3 patients underwent cranioplasty with Hydroset® osteoconductive cement and titanium mesh. RESULTS: The esthetic results were very satisfactory, especially for the skull dome, with a completely invisible and non-palpable cement/native skull junction. Scalp adherence to the cement was natural with maintenance of skin mobility. DISCUSSION: Bicortical calvarial bone reconstruction with Hydroset® cement is technically easy to perform, gives very good results, with an uneventful outcome, and induces lower costs.

[Depressor anguli oris sign (DAO) in facial paresis. How to search it and release the smile (technical note)]. / Signe du Depressor Anguli Oris (DAO) dans les parésies faciales. Comment le rechercher et libérer le sourire (note technique).

INTRODUCTION: After facial paralysis recovery, it is common to note a co-contraction between depressor anguli oris (DAO) muscle and zygomatic muscles. This DAO co-contraction will "obstruct" the patient's smile. The purpose of this technical note is to show how to find the DAO sign and how to free up the smile. TECHNICAL: This co-contraction between the zygomatic muscles and DAO research is placing a finger on marionette line, asking the patient to smile: we perceive a rope under the skin corresponding to the abnormal contraction and powerful DAO. A diagnostic test with lidocaine injection into the DAO can be performed to confirm the diagnosis. The treatment of pathological DAO's contraction can be by injection of botulinum toxin in the DAO, or by surgical myectomy. In all cases, a speech therapy complete the treatment. CONCLUSION: The DAO sign is a semiological entity easy to find. His treatment releases smile without negative effect on the facial expression as the DAO is especially useful in the expression of disgust.

Inferior turbinate hypertrophy radiofrequency management for children with cystic fibrosis.

OBJECTIVE: To evaluate, using radiofrequency techniques, the relevance and effectiveness of treatment of inferior turbinate hypertrophy in children with cystic fibrosis. MATERIALS AND METHODS: A study of patients with cystic fibrosis with hypertrophy of inferior turbinate who were being treated at Lisieux Hospital In-Patient Paediatric and ENT- Head and Neck Surgery Department. 41 patients were included in the study and followed over 2 years. We analyzed the postoperative phase and the effectiveness of treatment, through clinical and radiological examination. RESULTS: A clinical improvement of symptoms is observable from the third month after surgery in 100% of cases. However, we noted a loss in the effectiveness of radiofrequency on the turbinate tissue one year following operation, which worsens with time. However, the postoperative results remain satisfactory at 1 year and 2 years. CONCLUSION: Radiofrequency is, in our opinion, the treatment of choice for inferior turbinate hypertrophy in children with cystic fibrosis. It combines a simple and low-risk effect with effective preservative treatment. However, the benefits of radiofrequency fade with time. Nonetheless, this technique yields postoperative results that remain satisfactory beyond 2 years. It is often useful to consider a new session after this date.
