Filter by:Previous studies have demonstrated that patients frequently undergo significant decision conflict regarding major medical decisions in otolaryngology. There lack validated tools available for decision support for patients. While limited evidence has demonstrated that clinical decision support tools can alleviate decision conflict for patients with diagnosis in otolaryngology, conversational language models were not employed in these studies and may provide additional benefit in this context. This study seeks to evaluate the efficacy of using ChatGPT, a conversational language model with basic clinical knowledge, in alleviating decision conflict for patients with new diagnosis in otolaryngology. For this pilot study, vestibular schwannoma, a benign tumor that develops on the vestibular nerve with known clinical equipoise, has been chosen for the initial study diagnosis. Efficacy will be evaluated by comparison of responses to the Decisional Conflict Scale (DCS) and Satisfaction with Decision (SWD) scores between a group given training in ChatGPT and a control group (no ChatGPT training).
The purpose of this study is to evaluate the vestibular effects of gamma-knife radiosurgery, as part of the treatment of vestibular schwannoma.
Vestibular schwannomas are primarily benign (WHO grade I) tumors originating from the Schwann cells of the vestibular nerve and are among the most common tumors of the skull base. Common treatment options are surgical tumor resection or targeted radiation therapy. The special challenge of surgical treatment is the functional preservation of the cranial nerves, especially the cochlear and facial nerves. Perioperative ischemia of the cochlea and cochlear nerve is postulated as the underlying mechanism of postoperative hearing loss. Ischemic preconditioning is a non-invasive procedure that triggers the release of vasoactive cytokines and mediators by repeated short-term induction of limb ischemia. Improved perfusion of critically perfused end organs as well as a reduction of cerebral infarct volumes has already been shown in other pathologies. In the planned study, possible neuroprotective effects of remote ischemic preconditioning on postoperative hearing as well as facial nerve function in patients with vestibular schwannomas will be examined.
Patients with acoustic neuroma had several treatment options. One of standard treatment is to receive the Gamma knife stereotactic radiosurgery, other options included suboccipital craniotomy and conservative treatment. Thus, shared decision making (SDM) is necessary to aid patients to choose an appropriate treatment that suits their needs. The investigators have developed a decision aids (DAs) and plan to conduct a randomized controlled trial (RCT) to evaluate its impact on acoustic neuroma patients. The measurements include a battery of interview-based questionnaires and evaluations of decision regret and post-treatment depression. The investigators expect the DAs would benefit the intervention group in the aspects of knowledge, communication and anxiety status during and after their treatment sessions.
It is a Prospective descriptive hospital based clinical study to determine the value of introduction of endoscope after microscopic excision of cerebello-pontine angle lesions to estimate the following : 1. Intraoperative judgement of lesions excision, residual parts, visualization and operative corridor pre and after endoscope introduction. 2. Post-operative tumor control confirmed comparison between pre and postoperative MRI. 3. Postoperative complications, advantages and disadvantages compared with these when use pure microscopic excision from the literature
