Laryngopharyngeal reflux as a potential cause of persistent local neck symptoms after total thyroidectomy

Purpose Local neck symptoms (LNS) may be related to goiter, but are also reported by patients suffering from laryngeal–pharyngeal reflux (LPR). The aim of this study was to investigate whether LPR could play a role in the persistence of some LNS after total thyroidectomy (TT). Methods A consecutive case series of 160 patients with multinodular goiter (MNG) candidate for TT were included in this study. Each patient was closely studied for both the thyroid pathology and reflux disease before and 6 months after surgery to assess the persistence of LNS after surgery. Results Only throat discomfort showed a significant improvement (p = 0.031) after surgery. On the other hand, swallowing and voice disorders persisted after surgery in 82.3% and 77.3% of patients, respectively (p = 0.250 and p = 0.062), such as the correlated reflux laryngopharyngitis (p = 0.5). Conclusions LPR can be considered a predisposing factor or an important concurrent causa to the persistence of LNS after TT, in particular for swallowing disorders and voice disorders. In patients with non-toxic MNG who complain of local neck symptoms, the investigation of a possible coexistence of a reflux disease is appropriate before surgery. Patients should be informed about the possibility that some symptoms can persist even after removal of the goiter.
