The objectives of this study were to emphasize the importance of preoperative laryngeal examination before thyroidectomy by investigating the incidence of coincident abnormal laryngeal conditions that impair the quality of voice, and evaluate the usefulness of the "thyroidectomy-related voice questionnaire" as a screening tool.
Five hundred consecutive patients scheduled to undergo thyroidectomy underwent preoperative laryngeal examination and voice analysis and completed the questionnaire. According to the laryngeal examination results, patients were classified into normal and abnormal groups. Acoustic-analysis results and questionnaire scores were compared between the two groups, and correlations between acoustic parameters and questionnaire scores were evaluated. The cutoff score of the questionnaire that can effectively discriminate between the two groups was also determined.
The incidence of abnormal laryngeal conditions was 35.8%. The most common finding was laryngopharyngeal reflux (27.2%) followed by vocal nodule (4.8%), vocal polyp (1.8%), vocal cord palsy (1.2%), Reinke's edema (0.4%), vocal cyst (0.2%), and vocal sulcus (0.2%). The perceptual grade of voice quality (0.33 ± 0.49 for normal group vs. 0.65 ± 0.62 for abnormal group, P = 0.000) and the questionnaire scores (3.21 ± 5.47 for normal group vs. 13.41 ± 11.67 for abnormal group, P = 0.000) of the two groups were significantly different, and there was a significant correlation between objective voice parameters and questionnaire scores. A questionnaire score of 5 showed the best sensitivity (74%) and specificity (71%) in discriminating between the two groups. CONCLUSIONS : The incidence of coincident abnormal laryngeal conditions is relatively high; therefore, voice screening before thyroidectomy is important. The "thyroidectomy-related voice questionnaire" is a simple and effective screening tool to detect preexisting laryngeal disorders that can affect the quality of voice.

This study analyzed the temporal changes of voice quality after thyroidectomy and assessed the predictive perioperative parameters of postthyroidectomy voice disorder (PTVD).
This American Head and Neck Society (AHNS) consensus statement discusses the techniques of laryngeal examination for patients undergoing thyroidectomy and parathyroidectomy. It is intended to help gui...
The growing awareness of increased X-ray exposure to the public has led to the propagation of several methods for reducing the radiation dose during CT examination. Low-dose CT protocols do not, howev...
Thyroidectomy is a common surgery. Routine searching of the recurrent laryngeal nerve is the most important strategy to avoid palsy. Neuromonitoring has been recommended to decrease recurrent laryngea...
The current study used a three-dimensional (3D) computational laryngeal model to investigate the effect of false vocal folds (FVFs) on laryngeal flow resistance.
The purpose of this study is to explore quantitatively the hypothesis that "resonant voice," may enhance recovery from acute laryngeal phonotrauma, based on molecular assays from human lar...
The purpose of this study is to evaluate if intraoperative neuromonitoring associated to neurostimulation of recurrent laryngeal nerve reduce the rate of recurrent laryngeal palsy respect ...
The purpose the study is to determine the genetic causes of specific voice disorders that run in families. Researchers are particularly interested in two conditions; 1. Spasmodic dysph...
This study is to evaluate the level of anxiety, and to check the correlation of induction dose and the amount of sevoflurane to keep anesthetic depth in in female patients undergoing thyro...
Endoscopic thyroidectomy has been used to treat thyroid diseases in China. However, whether this technique is rational to treat thyroid carcinoma is still in controversy. The diagnosis of ...
Pathological processes that affect voice production, usually involving VOCAL CORDS and the LARYNGEAL MUCOSA. Voice disorders can be caused by organic (anatomical), or functional (emotional or psychological) factors leading to DYSPHONIA; APHONIA; and defects in VOICE QUALITY, loudness, and pitch.
Pathological processes involving any part of the LARYNX which coordinates many functions such as voice production, breathing, swallowing, and coughing.
Cancers or tumors of the LARYNX or any of its parts: the GLOTTIS; EPIGLOTTIS; LARYNGEAL CARTILAGES; LARYNGEAL MUSCLES; and VOCAL CORDS.
That component of SPEECH which gives the primary distinction to a given speaker's VOICE when pitch and loudness are excluded. It involves both phonatory and resonatory characteristics. Some of the descriptions of voice quality are harshness, breathiness and nasality.
Inflammation of the LARYNGEAL MUCOSA, including the VOCAL CORDS. Laryngitis is characterized by irritation, edema, and reduced pliability of the mucosa leading to VOICE DISORDERS such as APHONIA and HOARSENESS.
