Filter by:Randomised study to evaluate the outcomes of mastoid cavity obliteration by muscle versus bone in canal wall down tympanomastoidectomy in cholesteatoma surgery
The goal of this interventional study is to learn about the effect of mastoid process status and the method of ossicular reconstruction on the results of the procedure transcanal endoscopic management of patients with localized atticoantral cholesteatoma
In case of surgical procedures in the head and neck region, MRI in combination with CT of the bone is often the standard modality to visualise bony landmarks for planning, navigation and risk assessment. An important downside of a CT scan is the associated radiation exposure, especially in children. An additional downside is the sedation or general anaesthesia needed for both the MRI and CT scan session in very young children. These downsides could be removed if the CT scan can be substituted by an MRI sequence that can provide the same information as CT. This project aims to determine the feasibility of recreating CT like images of the craniofacial bones from MRI images using machine learning techniques.
Adult patients referred to the ENT surgery department of the Hospices Civils de Lyon with cholesteatoma that had never been operated on. All patients will benefit from surgical management for cholesteatoma initially in the operating room under general anesthesia. The surgical technique (closed technique) is the reference technique for the management of cholesteatoma in adults. It involves a cartilaginous removal to reconstruct the attical region. Then a filling material is used to fill the mastoid (GlassBONE™ or Bonalive™), and above all to stabilize the cartilaginous fragment to prevent a recurrence.
Chronic otitis media (COM) has a significant impact on health issues since prehistoric time. It is a global disease, seen in all the continents of world having different environmental and socioeconomic background. COM is characterized as a permanent abnormality of the pars tensa or flaccida, most likely a result of earlier acute otitis media, negative middle ear pressure or otitis media with effusion. COM squamous active (cholesteatoma) is a type of COM, which is a mass formed by keratinizing squamous epithelium in the middle ear and/or mastoid, subepithelial connective tissue and by the progressive accumulation of keratin debris with/without surrounding inflammatory reaction.
Background: Cholesteatoma is a potentially life-threatening inflammatory lesion that causes hearing loss, ear discharge, and ear pain, and serious complications. For the past several decades, most studies of cholesteatoma have been restricted to microscopic ear surgery. However, a growing body of evidence suggests endoscopic ear surgery is a safe, minimally invasive approach for cholesteatoma management. This thesis aim to investigate and compare the clinical effect between endoscopic and microscopic ear surgery of cholesteatoma. Materials and methods: The retrospective study included 186 patients with cholesteatoma who received endoscopic or microscopic ear surgery from 11 otorhinolaryngology centers between November 2016 and March 2021. Patients were followed-up for at least 1 year. Audiometry improvement, treatment cost, time, graft success rate and recurrence rate were assessed after surgery.
the main objective of the study is to compare endoscopic transcanal tympanoplasty with attico-antrostomy with endoscopic assisted canal wall up mastoidectomy in treatment of limited attic cholesteatoma.
The aim of this study is to assess the accuracy of preoperative HRCT of the temporal bone combined with the preoperative audiologic assessment compared with the intraoperative endoscopic middle ear finding.
Cholesteatoma is a destructive lesion that progressively expands in the middle ear, mastoid or petrous bone and leads to destruction of the nearby structures. Erosion, which is caused by bone resorption of the ossicular chain and otic capsule, may cause hearing loss, vestibular dysfunction, facial paralysis and intracranial manifestations
Previous studies demonstrated the high diagnostic value of non-echoplanar diffusion weighted magnetic resonance imaging (non-EP DWI) for residual cholesteatoma. However, limited data are available regarding a suitable length of imaging follow-up. The present study aimed to determine the optimal duration of non-EP DWI follow-up for residual cholesteatoma
