Mucosal inflammation in the pharynx and larynx was investigated in patients with the lump sensation in the throat.
The incidence of m u cosal inflammation in the pharynx was 74%,52% in the larynx on inspection. Mucosal inflmmation findings were classified into diffuse type, local type and normal type.36% were diffuse type,48% local type and 18% normal type. The relation between the local findings and symptoms was investigated by observing the clinical course. Symptoms improved with the improvement of local finding in most patients with diffuse type, but not in most patients with local type.
Bacteriological study of oropharynx revealed that the incidence of identifying Haemophilus group was relatively high.
Histological study on posterior wall in pharynx indicated that cell infiltration was frequently observed in diffuse type.
We speculated that the lump sensation in the throat was caused by mucosal inflammation, particularly, in the diffuse type.
