“…[4][5][6][7][8][9][10][11][12][13][14][15][16][17] Yeung found that preoperative voice and laryngeal examination is significant and reported dysphonia in 9% of cases, with 22% of laryngoscopic abnormalities, 4% of decreased vocal fold mobility and just one case of recurrent laryngeal nerve palsy. [9] Keilmann reported 43% of postoperative voice disorders: 12% of cases persisted 1 year after surgery (without any recurrent laryngeal nerve palsy); dysphonia occurred in 25% of cases after total thyroidectomy, 11% after unilateral lobectomy and only 5% of cases when the external laryngeal nerve was identified and preserved.…”

“…All these changes had resolved at the 2-week postoperative checkup except for decreased speaking fundamental frequency. [12] Causes of postoperative voice impairment The causes of voice disorders without recurrent laryngeal nerve palsy are probably multiple, including external laryngeal nerve injury; cricothyroid muscle injury; large laryngotracheal skeleton dissection, especially when the infrahyoid muscles are sectioned; and orotracheal intubation. Like Hong, we believe that large dissection is responsible for the majority of rapidly recovering postoperative voice disorders.…”

“…[1][2][3] However, some patients report subjective post-thyroidectomy voice disorders, for which the pathogenesis has not been clearly elucidated.

It was designed to determine the frequency of subjective voice disorders after total thyroidectomy and to establish the recovery time and the frequency of persistent voice disorders after a 1-year follow-up.…”

“…Several causes such as orotracheal intubation [5]; modification of the vascular supply and venous drainage of the larynx [6]; cricothyriod dysfunction [5][6][7]; laryngotracheal fixation with impairment of vertical movement [3,5,6,8]; strap muscle malfunction due to denervation or direct injury (section); local pain in neck; and/or a psychological reaction to the postoperative situation have been postulated. However, there is inconsistency in the cited results.…”

Total thyroidectomy (TT) is a surgical procedure which involves complete removal of the thyroid gland, usually done in massive goitre compressing the trachea and esophagus, hyperthyroidism and carcinoma of thyroid gland. Laryngeal nerve damage is one of the most feared complications after TT which can lead to permanent changes in voice. Recent research suggests the occurrence of voice changes without any visible laryngeal nerve damage. Present study attempts to compare the pre and post-operative voice characteristics in individuals with total thyroidectomy without any laryngeal nerve damage. A total of 27 subjects (21 females and 6 males) who underwent total thyroidectomy participated in the study. Their recorded phonation of vowel/a/was subjected to two types of analyses viz. Perceptual analysis (using CAPE-V rating scale) and Acoustic analysis (using Multi Dimensional Voice Profile). Results of perceptual analysis indicated slight decrease in overall severity, roughness and breathiness and a slight increase in strainness, in only males. Acoustic analysis findings supported perceptual results with minimal changes in most of the parameters. The results suggest that after total thyroidectomy, in the absence of visible laryngeal nerve damage, functional changes in voice are minimal and temporary in nature. This study provides an insight to Otolaryngologists and Speech Language Pathologists about the voice characteristics in individuals with thyroidectomy, enabling them to formulate appropriate therapy protocol for this population. It further attempts to sensitize surgeons and physicians on the need for referral of this population to Speech Language Pathologist in the event of dysphonia.Keywords Total thyroidectomy Á Perceptual analysis Á Acoustical analysis Á Laryngeal nerve damage Total thyroidectomy (TT) is one of the surgical options for individuals with thyroid problems. This procedure involves complete removal of the thyroid gland and is usually done in cases of massive goitre compressing the trachea and esophagus, in cases of hyperthyroidism or carcinoma of thyroid gland. The intricate and delicate anatomic structures for voice production lie in close proximity to thyroid gland and are vulnerable during operations on the thyroid.Complications subsequent to TT may range from minor (post operative seroma) to major ones (injury to laryngeal nerve). Injury to laryngeal nerve can be either due to injury to external branch of superior laryngeal nerve (SLN) or recurrent laryngeal nerve (RLN). Reported risk of SLN injury varies from 0.3 to 13% [1]. The estimated frequency of RLN injury fluctuates between 5 and 10%, of which 5% are temporary and between 0.8 and 1.7% are permanent [2].Voice changes due to SLN and RLN injury may also be associated with laryngotracheal fixation with impairment of vertical movement or by temporary malfunction of the strap muscles after surgery. Typical voice symptoms after surgery are vocal fatigue during phonation and with high pitch and singing voice [3]. People with injury to...

“…These authors performed investigations before and after treatment of hypo-and hyperthyroidism with reported time intervals from 7 days to 17 weeks, but did not further comment on the severity of thyroid dysfunction and the time course of development of recovery of the changes in pitch. A further study observed a decrease of the fundamental frequency of speaking 4 days after thyroid ablation (51). Although the cause for the slowing of speech is difficult to interpret, increased intervals between the different words (see Fig.…”
