Objectives: To evaluate the role of Stroboscopic research instrument in the diagnosis of laryngopharyngeal reflex patients.

Methods: Patients coming to otorhinolaryngology OPD after informed consent were grouped into cases and controls according to the RSI Score (≥13 and < 13, respectively). Matching was performed between cases and controls according to age, sex, and body mass index. All the subjects underwent laryngeal endoscopy and videostroboscopy, and findings were evaluated using the Reflux Finding Score (RFS) and the Stroboscopic Research Instrument (SRI) score, respectively.

Results: For the 86 patients (43 cases and 43 controls) in this study, the mean RFS was 8.60 ± 2.59 among the cases and 4.98 ± 2.45 among the controls. Among the cases, only 76.7% showed a high RFS (≥7). The means SRI score in cases were 79.60 ± 73.85 and in controls were 23.86 ± 41.76. In the SRI, the amplitude, symmetry, duration of closure, and mucosal wave parameters were significantly different between cases and controls. We also found a weak positive correlation between the SRI score and RFS in cases of LPR.

Conclusion: Our study tried to establish the role of SRI in the objective evaluation of LPR patients and found weak correlation between laryngoscopic and stroboscopic findings using standardized instruments.
