“…9,10 Recent research of the chest has been conducted using dynamic digital radiography (DDR), which is a technique with high temporal resolution that uses pulsed X-rays.

BackgroundAlthough flexible laryngoscopy (FL) is the reference modality for diagnosing vocal cord paralysis (VCP), FL involves patient discomfort and insertion intolerance. Dynamic digital radiography (DDR) with high spatial and temporal resolution is easier to use and less invasive when evaluating VCP.MethodsSeventy‐eight patients underwent FL and DDR before and after neck surgery. Qualitative and quantitative vocal cord movement (VCM) evaluations were conducted. Patients with postoperative VCP were followed‐up regularly.ResultsDDR exhibited diagnostic performance with 67% sensitivity and 100% specificity. The cutoff for VCM was 2.4 mm, with DDR exhibiting 100% sensitivity and 78% specificity. All cords with transient VCP had positive VCM at both 3 weeks and 2 months. Additionally, 50% and 75% of cords with permanent VCP had negative VCM at 3 weeks and 2 months, respectively.ConclusionsDDR is promising for the diagnosis of postoperative VCP and early prediction of permanent postoperative VCP.
