Abstract
The article is devoted to the influence of pharyngolaryngeal reflux on the voice acoustic parameters in patients before and after the antireflux surgery (fundoplication). The study involved 12 patients aged 33 to 64 years with a confirmed impedance–pH monitoring diagnosis of gastroesophageal reflux disease. The control group included 10 patients aged 18 to 33 years. These subjects did not have any upper respiratory diseases (including pharyngolaryngeal reflux) and gastrointestinal tract diseases. Computer voice analysis was used to objectively evaluate the voice acoustic parameters. In patients before fundoplication, a statistically significant increase in Jitter and Shimmer parameters was observed in 100% of cases compared with the control group (p ≤ 0,05). In the late postoperative period, 6 months after surgery, the analysis of acoustic parameters of voice in the study group revealed: Jitter and Shimmer indicators in 100% of cases significantly decreased compared to the preoperative values (p ≤ 0,05), which indicates an improvement in voice function. Jitter and Shimmer were the most diagnostically significant parameters.
