“−” means that the pharyngeal tissue was normal and no lesion was observed; “+” indicates that the squamous epithelium of pharyngeal mucosa showed mild hyperplasia and a small amount of inflammatory cells infiltrated under the mucosa. “++” means the mucosal squamous epithelium of the pharynx was obviously hyperplasia with inflammatory cells infiltrating into the lower layer. “+++” means the pharyngeal mucosal squamous epithelium shows moderate or severe hyperplasia with submucosal inflammatory cells.
