The PENTOCLO protocol achieved clinical and radiological regression of ORN with, in parallel, a reduction of the indications for major surgery. These preliminary results need to be confirmed by prospective studies comprising quality of life assessment.
In first-line, clearing out blood-clots and bidigital compression are recommended. In case of persistent bleeding, local anesthesia with a vasoconstrictor is essential before nasal diagnostic and therapeutic procedures. When the origin of bleeding is not anterior, nasal endoscopy is an essential procedure, identifying the bleeding site in most cases. In case of active bleeding, cauterization is recommended but is only feasible if the bleeding site is clearly visible. When the bleeding site is not identifiable or the first measures failed, anterior packing may be performed by a non-specialist physician. Epistaxis requires subsequent nasal endoscopy performed by an ENT specialist. Patients should be informed of the measures to be taken in case of epistaxis at home, and the risks associated with the various treatments.
Vestibular lesions are found after cochlear implantation in 23-100 % of cases. The objectives of this study were to evaluate the vestibular function before and after implantation while focusing its feasibility. This prospective study included 35 patients, mean age 49 years. Each patient enjoyed a vestibular balance before and after implantation in a median period of 5 months compared to surgery. Vestibular evaluations were performed using vestibular-evoked myogenic potentials (VEMP) and videonystagmography. Before implantation, the VEMPs were bilateral in 73 % of cases. They are modified after implantation for 13 patients, including 12 missing or reduced potentials on implanted side (p = 0.0015). Caloric tests found themselves a significant decrease in the reflectivity of the ear implanted (p < 0.0001). Vestibular symptoms were independent of changes on vestibular tests. No relation was found between the occurrence of post-operative vestibular symptoms and the results of the vestibular investigations. However, the achievement of these exams is not easy especially for children and only part of the vestibule is tested. In conclusion, the vestibular assessments help to choose the side of implantation, assess the pre-operative vestibular condition and assess and locate vestibular lesions induced. Further tests should enable a complete vestibular assessment.
Before any decision to modify antithrombotic treatment, it is recommended to screen for overdose and assess the risk of thrombosis. In stented patients, dual antiplatelet therapy must be maintained during the month following stenting and, if possible, for 3 months. In epistaxis with antivitamin K (AVK) overdose controlled by packing, corrective measures are based on the International Normalized Ratio (INR). In uncontrolled epistaxis, it is recommended to stop AVK, administer antidotes and regularly monitor INR. In case of intravascular embolization, it is not recommended to alter anticoagulant treatment.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations鈥揷itations 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.
