We aimed to assess the utility of preoperative routine flexible laryngoscopy (FL) by looking at the incidence, clinical significance and predictors for preoperative vocal cord paresis (VCP) and incidental laryngopharyngeal conditions (LPC) in our consecutive cohort.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>A total of 302 patients underwent laryngeal examination by an independent otorhinolaryngologist and were specifically asked about voice\/swallowing symptoms suggestive of VCP 1\u00a0day before surgery. As well as vocal cord (VC) mobility, the naso\u2010pharynx and larynx were examined using FL. Any VCP and\/or LPC was recorded. VCP was defined as reduced or absent movement in one or more VC. An LPC was considered clinically significant if the ensuing thyroidectomy was changed or deferred.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Seven (2.3 %) patients had preoperative VCP, while an additional seven patients had an incidental LPC. Of the seven VCPs, five were caused by previous thyroidectomy, while two were caused by a benign goitre. The incidence of asymptomatic VCP in a previously non\u2010operated cohort was 1\/245 (0.41 %). Voice\/swallowing symptoms (<jats:italic>p<\/jats:italic> = 0.033) and previous thyroidectomy (<jats:italic>p<\/jats:italic> &lt; 0.001) were the two significant predictors for VCP. The seven incidental LPCs were vallecular cyst (<jats:italic>n<\/jats:italic> = 1), VC scar and polyp (<jats:italic>n<\/jats:italic> = 2), nasopharyngeal cyst and polyp (<jats:italic>n<\/jats:italic> = 3) and redundant arytenoid mucosa (<jats:italic>n<\/jats:italic> = 1); however, as they were benign, all seven patients proceeded to thyroidectomy as planned.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Given the low incidence (0.41 %) of asymptomatic VCP in a previously non\u2010operated cohort and that none of the seven LPCs were considered clinically significant, routine preoperative laryngoscopic examination should be reserved for those with previous thyroidectomy and\/or voice\/swallowing symptoms.<\/jats:p><\/jats:sec>","DOI":"10.1007\/s00268-013-2259-3","type":"journal-article","created":{"date-parts":[[2013,9,25]],"date-time":"2013-09-25T02:25:37Z","timestamp":1380075937000},"page":"385-391","source":"Crossref","is-referenced-by-count":34,"title":["Evaluating the Incidence, Clinical Significance and Predictors for Vocal Cord Palsy and Incidental Laryngopharyngeal Conditions before Elective Thyroidectomy: Is There a Case for Routine Laryngoscopic Examination?"],"prefix":"10.1002","volume":"38","author":[{"given":"Brian Hung\u2010Hin","family":"Lang","sequence":"first","affiliation":[{"name":"Division of Endocrine Surgery, Department of Surgery University of Hong Kong, Queen Mary Hospital 102 Pokfulam Road Pokfulam SAR Hong Kong"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kevin Ka\u2010Wan","family":"Chu","sequence":"additional","affiliation":[{"name":"Division of Endocrine Surgery, Department of Surgery University of Hong Kong, Queen Mary Hospital 102 Pokfulam Road Pokfulam SAR Hong Kong"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Raymond King\u2010Yin","family":"Tsang","sequence":"additional","affiliation":[{"name":"Division of Otorhinolaryngology Department of Surgery, University of Hong Kong Queen Mary Hospital Pokfulam SAR Hong Kong"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kai Pun","family":"Wong","sequence":"additional","affiliation":[{"name":"Division of Endocrine Surgery, Department of Surgery University of Hong Kong, Queen Mary Hospital 102 Pokfulam Road Pokfulam SAR Hong Kong"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Birgitta Yee\u2010Hang","family":"Wong","sequence":"additional","affiliation":[{"name":"Division of Otorhinolaryngology Department of Surgery, University of Hong Kong Queen Mary Hospital Pokfulam SAR Hong Kong"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2013,9,25]]},"reference":[{"key":"e_1_2_7_2_2","unstructured":"The Surgical Outcomes Monitoring & Improvement Program (SOMIP) report volume 3 (July 2010\u2010June 2011).
