Epiglottis cysts do not require amoxicillin, let alone for how long, if there is no clear causative bacterial infection.
Epiglottis cysts are most often formed by inflammatory stimuli causing obstruction of submucosal mucous gland ducts or, in a few cases, due to dilatation of the glandular lumen and retention of mucus following obstruction of the mucous gland ducts during development. Laryngoscopic occlusion of most of the cyst wall and laser vaporization of its wall to prevent recurrence is the mainstay of treatment for this disease.
Amoxicillin belongs to the penicillin class of antibiotics and has good antibacterial activity against Streptococcus spp. such as Streptococcus pneumoniae, Streptococcus haemolyticus and other Streptococcus spp., penicillinase-less staphylococci, Enterococcus faecalis and other aerobic gram-positive cocci, Escherichia coli, Haemophilus influenza, Neisseria gonorrhea and other aerobic gram-negative non-producing-lactamase strains of bacteria and Helicobacter pylori.
It is evident that oral amoxicillin is not required for epiglottis cysts, and there is no indication for amoxicillin for the treatment of epiglottis cysts. It is recommended to follow the doctor’s instructions for standardized treatment after active medical treatment, and avoid blind self-medication.
