OBJECTIVES: We present a prospective study assessing the real incidence, aetiology, and evolution of @entity73 following total thyroidectomy. @entity1 AND METHOD: Sixty-six @entity1 who underwent total thyroidectomy between 2003 and 2006 were included, recording demographic and analytic variables, with emphasis on subjective vocal changes observed after surgery, measured by means of the GRABS scale. A control group of 25 @entity1 operated under general anaesthesia and oro-tracheal intubation was chosen using random sampling. RESULTS: In 30 @entity1 (45.5 %), @entity7441 was observed. Among these, only 2 (3 %) were permanent, and 11 were due to @entity16 (10 inferior and 1 superior laryngeal nerves). In 8 @entity1 (12.2 %), GRABS score was above 5. In the rest of these 30 @entity1 , the complaint was a single decreased tone (10 cases), lack of intensity (9 cases) and vocal fatigue (3 cases), always with a GRABS score equal to or less than 2 points. The most significantly related factor with the onset of @entity7364 was the section of @entity10874 muscles (OR=12.5). CONCLUSIONS: Dysphonia is a common complication of total thyroidectomy, but its incidence is not always related to @entity128 . Some technical (and sometimes avoidable) factors, such as the section of prelaryngeal muscles, could have an important relationship with this adverse event.
