Filter by:Actual CT scanners overestimate stapes piston size, and do not represent a valuable technique for their follow-up, especially in case of complication. Ultra-high resolution has not yet been evaluated in this setting.
Dexmedetomidine continuous intravenous infusion vs. remifentanil target-controlled infusion conscious sedation for stapedotomy/stapedectomy- a prospective, single-center, double-masked randomized trial The goal of this clinical trial is to compare monitored anesthesia care with continuous intravenous dexmedetomidine vs. remifentanil target-controlled infusion in patients undergoing stapedotomy or stapedectomy for otosclerosis. The aims of this research are: - to assess the patient's satisfaction with each sedation regimen - the surgeon will also grade their satisfaction regarding the surgical field The investigators will monitor and analyze the vitals during and after the intervention and document any intra- and postoperative complications. Participants will be randomly assigned to receive either dexmedetomidine or remifentanil, and the patient, the surgeon, and the investigator will not be aware of the treatment administered.
Considering the long-term results of otosclerosis surgery performed in our clinic, it was observed that in addition to the improvement in air conduction hearing, which indicates conductive hearing, which is the main success of the surgery, there was also an improvement in bone conduction hearing, which indicates sensorineural hearing, in patients using bone cement. Our study aimed to examine the effect of bone cement use in otosclerosis surgery on long-term hearing thresholds and bone conduction.
Titanium pistons cause MRI artifacts that prevent interpretation of the vestibule. This disadvantage is not present on CT but the vestibule is not visible. Hence the interest in creating a model with 6 reference cuts in order to position the utricle and the saccule in the vestibule in CT. Furthermore, the scanner has fewer contraindications, greater availability and a shorter examination time than MRI.
This study will be conducted on patients with otosclerosis attending Assiut University Hospital and undergo stapedectomy operation Evaluation of each patient will conducted preoperatively and 3 month postoperatively Patient will undergo tinnitogram and tinnitus handicap questionnaire before and after the operation to measure improvement in hearing and tinnitus
Otosclerosis is a relatively frequent pathology, of multifactorial origin with genetic and hormonal part, predominantly in women. This disease causes a disorder of the bone metabolism of the middle and inner ear, responsible for a progressive deafness, which can become severe. Several elements are necessary to make the diagnosis of otosclerosis: the clinical examination and questioning, the audiometric assessment, and finally the temporal bone CT. The CT scan allows to detect foci of otosclerosis within the bone of the middle or inner ear. This diagnosis is sometimes difficult and requires interpretation by a trained radiologist. The investigators would like to evaluate the ability of a deep learning algorithm to detect these foci of otosclerosis, and to compare its diagnostic performance with a trained radiologist.
Our studies will systematically investigate and establish evidence on whether Cone-beam computed tomography (CBCT) of the temporal bone could be used in the diagnosis and treatment of otosclerosis and in the post-operative follow-up after stapedotomy.
The aim of this study is to compare the thickness of the stapes footplate measured with ultra high resolution CT in control patients, otosclerosis patients and chronic otitis media patients.
Aim of The Work The aim of this study is to compare hearing outcome and surgical complications between classic and reversal endoscopic stapedotomy. Patients and Methods Study design: This study is a randomized clinical study and will be carried out at Otorhinolaryngology department at Mansoura University Hospitals. The study will be conducted among 60 patients with otosclerosis who will undergo endoscopic stapedotomy. The patients will be divided into two groups. The first group (group 1) 30 patients will undergo endoscopic classic stapedotomy while the second group (group 2) 30 patients will undergo endoscopic reversal stapedotomy. The two groups will compared to each other as regard, A. Intra-operative time (in minutes) B. Hearing outcome. C. Surgical complications
This study aims to compare the Cone Beam and the multi-detector computed tomography for diagnosis and pre-operative evaluation of otosclerosis in patients addressed for conductive hearing loss with intact tympanic membrane. The study aims to show that the Cone Beam offers equivalent performances with lower radiation dosage in this indication
