Immediate Post-Operative Canal Management

The American Academy of Otolaryngology-Head and Neck Surgery recommends performing gentle aural toilet using atraumatic cleaning with suction under microscopic guidance, rather than irrigation, particularly given the post-surgical state 1, 2
The use of body-temperature saline solution or hydrogen peroxide is recommended for gentle lavage if necessary, with the American Academy of Otolaryngology-Head and Neck Surgery citing its safety and effectiveness 1, 3

Cancer patients are often immunocompromised from chemotherapy or radiation, placing them at higher risk for post-procedure otitis externa, according to the American Academy of Otolaryngology-Head and Neck Surgery 4, 5
The American Academy of Otolaryngology-Head and Neck Surgery suggests using only atraumatic suctioning under microscopic guidance in radiated or immunocompromised patients to minimize the risk of complications 2, 5

The American Academy of Otolaryngology-Head and Neck Surgery recommends providing close follow-up for immunocompromised or radiated patients to monitor for signs of infection, stenosis, or cholesteatoma formation 4, 5

The American Academy of Otolaryngology-Head and Neck Surgery advises patients to keep the ear completely dry during the healing period to prevent infection and promote healing 6, 7
Patients should not attempt self-cleaning, as the post-surgical canal is extremely tender and vulnerable to damage, and instead follow the recommended guidelines for ear drop administration, including lying with the affected ear upward, filling the canal, remaining in position for 3-5 minutes, and using gentle tragal pumping 6, 7, 3
