Assessment the presence of dysphonia following endotracheal intubation in surgical operations

Humans can produce a wide variety of voices that differ in pitch, loudness, and quality.About one-third of people experience dysphonia, which means improper voice production, at some point in their lives. During surgery endotracheal tube is inserted between the vocal folds and passes into the trachea to supply the lungs with oxygen Endotracheal intubation is generally regarded as a low-risk procedure, meaning that post-intubation adverse effects,including hoarseness and sore throat, laryngeal edema and laryngeal irritation. Aim of the study: To determine the incidence of dysphonia after endotracheal intubation in surgical operations. Methods: This study consisted of a random sample of 105 patients who will undergo elective surgeries under general anesthesia with endotracheal intubation. They divided into 3 groups according to duration of operation(group (A) less than 60 minute, group(B) 60-120 minute , group(C) more than 120 minute and less than 180 minute),Each patient was subjected to thefollowing survey study including this data(Patient Interview and history taking, Auditory Perceptual Assessment (APA), in3 steps ( 1 day before operation , at first day after operation then at 5th to7th days after operation).Results: With the evaluation made on the postoperative first day, it was found that there was significant change ofvoice quality with predominance of dysphonia grade II in 3 groups thenevaluation on the postoperative 5th to 7th days there was improvement in voice quality as there was no significantdifference between preoperative and postoperative 5th to 7th days evaluation Conclusions: voice changes after intubation are significant andtransient as it resolves within 1 week
