![]() Further research is needed to fully elucidate PLF's symptoms and treatment efficacy using the surgical indication we developed. A new hypothesis is proposed that the chronic disequilibrium experienced by many PLF patients is due to enhanced mobility of the utricle and not to endolymphatic hydrops. Using the perilymph-specific protein Cochlin-tomoprotein (CTP) as a diagnostic biomarker, we could prove that PLF could be responsible for disequilibrium and related auditory disturbances in these patients. Regarding questionnaires, the DHI and VSS are commonly used. ![]() Further, timely surgery showed improvements in hearing, with some benefits also seen in late-stage surgeries. In the literature, different methods are used to capture chronic UVH symptoms (i.e., 3 months ): history taking questionnaires like the Dizziness Handicap Inventory (DHI) and Vertigo Symptom Scale (VSS) scales like the Visual Analog Scale (VAS) and semi-structured interviews. Despite the notable absence of a control group in the study, the marked improvements in vestibular symptoms and substantial reductions in Dizziness Handicap Inventory (DHI) scores suggest that the observed benefits are attributable to the surgical intervention. Objective:This study was designed to observe the dizziness handicap inventory (DHI) scores in patients with BPPV (benign paroxysmal positional vertigo) before and after maneuver repositioning and aimed to discuss the values of DHI scores in the diagnosing and treatment of BPPV. The postoperative recovery from vestibular symptoms following PLF repair surgery was strikingly rapid, with 82% of cases demonstrating marked improvement within a week, even in chronic cases. Cases with antecedent events had significantly shorter intervals before surgery. In the DHI the patient answers 25 questions to identify difficulties that the patient may be experiencing due to their symptoms. We analyzed the characteristics of these 22 cases and evaluated the efficacy of PLF repair surgery in treating vestibular and auditory symptoms. The Dizziness Handicap Inventory (DHI) and the Motion Sensitivity Quotient (MSQ) are the most often used tools in the diagnosis of motion sensitivity. Clinically significant change 18 or more. Items are scored from 0-100, with higher scores indicating a greater perceived level of disability. This is a retrospective study of 22 cases treated with PLF repair surgery, selected based on our surgical indication. Dizziness Handicap Inventory (DHI) 25 item questionnaire measuring self-perceived disability due to unsteadiness and dizziness. By definition (Jaeschke et al., 1989) and as applicable to our study, MCIDs are the difference in gait speed required to trigger a change in a patients care trajectory. Perilymph Fistula (PLF), abnormal communication between the fluid-filled space of the inner ear and the air-filled space of the middle ear, is a significant cause of vestibular and auditory symptoms. In VR, common patient-reported outcomes include the Dizziness Handicap Inventory (DHI) and the Activity Balance Confidence (ABC) Scale. You just subscribed to receive the final version of the article
