Research progress on the mechanism of eustachian tube dysfunction after radiotherapy for head and neck tumors
Head and neck malignant tumors are one of the common malignant tumors.T he incidence of middle ear diseases such as secretory otitis media,adhesive otitis media,middle ear cholesteatoma,purulent otitis media,and chronic mastoiditis is high after radiotherapy for head and neck tumors,and the treatment effect is poor,seriously affecting the quality of life of patients.Eustachian tube dysfunction is the core factor of middle ear disease caused by radiotherapy for head and neck malignant tumors.The mechanism of eustachian tube dysfunction caused by radiotherapy is relatively complex.The article reviews its formation mechanism,aiming to provide reference for clinical treatment of middle ear disease after radiotherapy for head and neck tumors.
