Hello,
We follow Lippincott procedures in our clinics. In the cerumen impaction, removal procedure it indicates that ear lavage is contraindicated if the tympanic membrane is perforated, so I echo Charlotte in recommending there be an assessment of ear prior to initiating the procedure. We also use tap water. The Lippincott procedure does not specify the type of water to use, but it does cite this resource -
Schwartz, S. R., et al. (2017). Clinical practice guideline (update): Earwax (cerumen impaction). Otolaryngology–Head and Neck Surgery, 156(Suppl. 1), S1–S29.
In scanning the resource for the word "tap", it is mentioned as causing a higher incidence of malignant otitis externa in special populations. However, in our clinics, we provide instructions post-lavage for "reacidifying" the ear as outlined in the clinical practice guideline cited above to reduce the risk of infection. To my knowledge, we have had no safety events related to our procedure.
Happy to discuss further if needed. Best,
