What Researchers Did
This study reviewed the acute and chronic pathological changes in the ear caused by radiotherapy and discussed current medical management strategies.
What They Found
Researchers found that acute radiotherapy-induced external ear changes range from erythema and dry desquamation to moist desquamation and epidermal ulceration, while chronic changes include epithelial atrophy and subcutaneous fibrosis. Current medical management involves topical steroid treatment for external auditory canal (EAC) radiation dermatitis and topical antibiotic therapy for suppurative otitis externa.
What This Means for Canadian Patients
Canadian patients undergoing radiotherapy to the head and neck region should be aware of potential acute and chronic ear pathologies, such as skin irritation and tissue changes. Early recognition and appropriate medical management, including topical steroids or antibiotics, can help alleviate symptoms and manage complications affecting the external auditory canal.
Canadian Relevance
This study does not have a direct Canadian connection.
Study Limitations
A limitation is the undefined clinical effect of promising therapies like hyperbaric oxygen and pentoxifylline-vitamin E on soft tissue external auditory canal disease.
