Studies found only a little amount of evidence about the impact of septoplasty on the mechanism of voice production, as
well as vocal cord and laryngeal mucosal changes. Nasal obstruction is a common medical issue that is linked to changes in
the quality of resonance of voice. To assess patients with deviated nasal septum and inferior turbinate hypertrophy’s voice
alterations using laryngeal stroboscope before and after septoplasty and turbinectomy. In this prospective case–control
study, patients in group A had inferior turbinate hypertrophy and a nasal septal deviation, while participants in group B
were healthy controls who were matched for age and gender. All of the included patients had their laryngeal stroboscope and
acoustic voice characteristics evaluated both preoperatively and three months after surgery. Only the baseline evaluation of
healthy controls was done. We included 30 patients with mean age 24.43±7.81 years, and males accounted for two thirds
of the included cases, speech testing showed that Amplitude perturbation signifcantly improved post septoplasty with p
