Introduction: The dacryocystorhinostomy (DCR) procedure is linked to a high success rate; however, cases of tearing recurrence are not rare and should be managed efficiently. Thus, evaluating cases of DCR failure allows highlighting the factors significantly impacting the results in order to realize better controlled primary surgeries.
Material And Method: Twenty-eight patients were operated in our Otolaryngology Department for endoscopic revision of DCR failure between January 2019 and June 2022.
The purpose of the study is to evaluate the correlation between caloric test results and video head impulse test (VHIT) vestibulo-ocular reflex (VOR) gains in unilateral horizontal canal deficits in order to define a possible threshold value above which caloric deficits should be associated with predictable low VHIT VOR gains. Caloric test and VHIT were realised in 105 patients presenting with symptoms of rotational vertigo occurring within the last 2 weeks. The authors defined the cutoff value for a caloric abnormality as more than 15% of canal deficit, which allowed us to divide our patients on groups based on the severity of their caloric asymmetry.
