Role of dynamic slow motion video endoscopy in etiological correlation between eustachian dysfunction and chronic otitis media: A case-control study

Unveiling the Potential: A Comprehensive Review of Dynamic Slow-Motion Video Endoscopy for Eustachian Tube Dysfunction Evaluation

“…These cutting-edge technologies offer unprecedented insights into the dynamic behavior of various anatomical structures, revolutionizing the diagnostic and treatment planning processes. High-speed video endoscopy (HSV) stands out as a remarkable innovation, allowing for the capture of vocal fold vibrations at an exceptionally high frame rate, often surpassing 2000 frames per second [ 8 , 9 ]. By detecting subtle abnormalities in vocal fold vibration patterns, HSV contributes to diagnosing both benign and malignant lesions, thereby improving clinical outcomes [ 9 ].…”

“…Furthermore, DSVE has demonstrated improved diagnostic accuracy in identifying ETD. Studies have revealed significant differences in DSVE grades between ears affected with chronic otitis media and healthy ears, underscoring its potential as a diagnostic tool [ 7 , 8 ]. DSVE's ability to detect abnormalities that might evade detection with traditional techniques enhances its diagnostic utility.…”

“…DSVE's ability to detect abnormalities that might evade detection with traditional techniques enhances its diagnostic utility. The DSVE findings add another layer of diagnostic precision where clinicians can glean valuable preoperative insights into ETD with other nasal and nasopharyngeal pathologies in one setting when combined with diagnostic nasal endoscopy [ 8 ]. This synergistic approach enhances the overall assessment and helps in assessing the effects of interventions on ET function; DSVE enables clinicians to monitor treatment progress and tailor patient management strategies accordingly [ 11 ].…”

“…Few studies have raised doubts over its efficacy as a standalone test, where authors felt that its utility is significantly enhanced when combined with other complementary diagnostic techniques [ 12 , 21 ]. However, some other recent studies have recommended the utility of DSVE as a single modality that has outstood other tests for ETD, as it has the added advantage of diagnosing the nasal, paranasal, and nasopharyngeal conditions associated with ETD at the same sitting [ 6 , 7 , 8 ]. The findings of ETD with signs and symptoms related to COM correlate better with DSVE than any other investigation alone [ 6 , 7 , 8 , 22 ].…”

The findings of ETD with signs and symptoms related to COM correlate better with DSVE than any other investigation alone [ 6 , 7 , 8 , 22 ]. This is also supported by the DSVE value being higher in COM ears than in contralateral ears with a higher grade of ETD [ 7 , 8 ].…”
