Conclusion
Given the prevalence of CT imaging and cauterization in otologic
practice, especially in context of OE and NOE, we recommend imaging
patients before silver nitrate cautery if required. If imaging is
delayed we recommend contemporaneously documenting the use of silver
nitrate and highlighting this on request forms to avoid alarming
erroneous reports, unnecessary investigation and surgical procedures. We
also encourage discussions between otolaryngology and radiology
departments to educate all physicians on the potential appearance of
silver nitrate on CT imaging.
