Abstract
Establishing a relationship between a benign disorder and a malignant disease has a certain influence on clinical practice. Clinicians need to remain vigilant with patients with acid reflux disorders and rule out the possibility and presence of head and neck cancer.
Highlights
Refluxing does not stop at the esophagus
Previous studies have found that longterm corrosion of the esophagus by gastric acid could result in esophageal cancer [1]
The fact is that the patients may have laryngopharyngeal reflux (LPR) rather than gastroesophageal reflux disease (GERD)
Summary
Refluxing does not stop at the esophagus. The gastric acid continues upwards to the pharynx, larynx, oral cavity, and nasal cavity. Though, does not stop at the esophagus (Figure 1); the gastric acid continues upwards to the pharynx, larynx, oral cavity, and nasal cavity, which can cause certain discomfort, such as a foreign body sensation in the throat, difficulties swallowing, and hoarseness after awakening.
