L'ankylose de l'articulation temporo-mandibulaire (ATM) est définie comme une constriction permanente des mâchoires avec ouverture buccale inférieure à 30mm mesurée entre les incisives, survenant en raison d'une fusion osseuse, fibreuse ou fibro-osseuse. L'arthrose est une cause rare de l'ankylose de L'ATM. Nous rapportons un cas d'ankylose de l'ATM d'origine arthrosique, afin de préciser les particularités diagnostiques et thérapeutiques de cette entité pathologique assez rare.
Lymphatic malformation (ML), formerly called cystic lymphangioma is a benign hamartomatous tumor of lymphatic vessels. The onset of lymphangiomas is either at birth (60% to 70%) or up to two years of age (90%) and rare in adults. These malformations can occur in any region of the body, Lymphangiomas have marked predilection for the head and neck region (50%-70%). The most common location in the mouth is the dorsum of tongue. If the positive diagnosis is generally easy, the therapeutic management remains controversial. We report the clinical case of a 23-year-old adult patient with cystic lymphangioma on the floor of the oral cavity extending gradually to the right submandibular region. The clinically suspected tumor was thoroughly explored using tomodensitometry. The treatment consisted of complete resection by a cervicotomy with histological examination confirming the macroscopic diagnosis of cystic lymphangioma. Follow-up at 3 years showed no recurrence.
La fasciite nodulaire est une lésion bénigne à prolifération rapide de cellules myofibroblastiques, qui se développe aux dépens d'un fascia musculaire au sein du tissu sous-cutané. Sa croissance rapide et sa richesse cellulaire et mitotique font qu'elle est souvent prise à tort pour un sarcome. D'où l'importance de poser un diagnostic précis pour éviter des chirurgies inutiles et souvent mutilantes.Nous rapportons dans cette observation une localisation exceptionnelle de cette tumeur au niveau de la fosse infra-temporale.
Introduction: Myringoplasty remains a topical subject. Our study aims at analyzing the anatomical and functional results of cartilaginous myringoplasty, and also determining the main factors that could influence its results.Materials and methods: A retrospective study of 51 cases of tympanic perforations operated at the ENT department of the Hassan II University Hospital of Fez between January 2018 and November 2021. Only the patients with exclusive cartilage myringoplasty were included. The anatomical and functional results of cartilage myringoplasty were evaluated and analyzed according to several variables. The statistical analysis was performed using SPSS Statistics software.Results: The average age of our patients was 35, with a sex ratio of 2.45. The perforation was anterior in 58%, posterior in 12%, and central in 30% of the cases. The average pre-operative audiometric air bone gap (ABG) was 29.3 dB. The most commonly used graft was the conchal cartilage in 89% of cases. A complete cicatrization has been noticed in 92%, and at six months after surgery, a complete closure of the ABG has been observed in 43% of cases, a significant hearing improvement with an ABG between 11 and 20 dB in 24%, a hearing recovery with an ABG between 21 and 30 dB in 21%, and an ABG > 30 dB in 12% of the cases. A statically significant relationship (p<0.05) has been found between the functional or anatomical failure of the myringoplasty; the different predictive factors were: the young age (less than 16 years), the inflammatory state of the tympanic cavity, the anterior location, and large size of the perforation. Conclusion:Cartilaginous myringoplasty provides good anatomical and auditory results. The pre-operative predictive factors, such as age, complete and sufficient drying of the ear, the size and location of the perforation, and the size of the used cartilage, should all be considered for a better anatomical and functional outcome.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
