“…When these pressures exceed the capillary perfusion pressure of the vocal folds (24 mmHg), tissue ischemia and edema may result, and is usually more accentuated at the junction of the vocal processes and the posterior vocal fold. [15][16][17][18][19] That is why factors such as the size of the tube, size of the larynx, cough pressure, and duration of anesthesia are important in the interpretation of vocal symptoms postoperatively. In our study, there was an association between mean cuff pressure and throat clearing.…”

“…8 Endotracheal intubations change the patient's voice nevertheless the changes are neither too serious nor irreversible. 9 As Leonard and Charpred 10 and Kean et al 8 reported traumatic responses such as changes in connective tissues and granulomas can develop and persist for a few weeks to few months. Jitter can be used as a measure in evaluation of laryngeal and vocal pathology.…”

BACKGROUND Pharyngolaryngeal discomfort is a common cause of patient dissatisfaction after elective surgery. The difference in incidence of pharyngolaryngeal complications between endotracheal tube and Laryngeal Mask Airway (LMA) has popularised the use of the laryngeal mask airway. MATERIALS AND METHODS This prospective, randomised study included 60 patients of ASA class I and II of age 15 to 60 years undergoing elective minor surgeries. Postoperatively, interviews were performed at 6, 12 and 24 hours after anaesthesia. Post-anaesthetic sore throat and dysphagia were graded using a predefined verbal analogue scale. Voice analysis was done using computer software, Dr. Speech. RESULTS The incidence of sore throat at 6, 12 and 24 hours was significantly higher in ETT group than LMA. Dysphagia was more common in ETT at 6, 12 and 24 hours, but significant only at 6 hrs. There was significant difference in postoperative values of jitter, shimmer and HNR in ETT group when compared with preoperative values. Postoperative values of jitter and shimmer were significantly higher than preoperative values in LMA group. CONCLUSION Our study concludes that pharyngolaryngeal complaints occur more commonly with endotracheal tube than laryngeal mask airway.

The objective of the study was to assess and perceive the vocal and pharyngeal symptoms and acoustic changes of voice after short-term endotracheal intubation and to evaluate the relation between these changes and the endotracheal tube parameters, number of intubation attempts, duration of anaesthesia, experience of anaesthesiologist. A total of 108 patients were evaluated preoperatively, 1-2 and 24 h after extubation. The vocal and pharyngeal symptoms, voice acoustic characteristics and maximum phonation time (MPT) were evaluated to find the relationship with endotracheal tube parameters, number of intubation attempts, duration of anaesthesia, experience of anaesthesiologist. All vocal and pharyngeal symptoms increased significantly at 24 h and remained significantly increased at 24 h after general anaesthesia. The vocal acoustic parameters changed significantly at 1-2 h: decrease of MPT and increase relative average perturbation were recorded. The day after the short-term intubation: only noise to harmony ratio and habitual pitch remains significantly changed. The most important endotracheal tube parameters that affect significantly (P value <0.05) the vocal function were the size of tube, cuff volume and number of intubation attempts. In relation to the anaesthesia, the changes of the acoustic parameters did not associate significantly with the anaesthesia-related parameters. No statistically significant relationship between experience of an anaesthesiologist and changes of the voice after anaesthesia was detected. Though being short-term, endotracheal anaesthesia is an invasive procedure, and its temporary influence on vocal function is important.
