What information should be provided to a patient undergoing ear syringing?

Patient Information for Ear Syringing

Patients undergoing ear syringing should receive comprehensive information about the procedure, potential benefits, risks, contraindications, and aftercare instructions to ensure informed consent and minimize complications.

Procedure Information

• Explain that ear syringing (irrigation) is a procedure to remove impacted earwax using water at body temperature directed at the ear canal wall, not directly at the eardrum 1
• Inform patients that the procedure may involve pre-treatment with cerumenolytic agents (wax softeners) for 3-5 days to improve effectiveness 2
• Describe that water will be directed at the canal wall rather than straight toward the eardrum to minimize risks 1
• Explain that the procedure typically requires between 500-1000ml of irrigation fluid 3

Expected Benefits

• Inform patients that successful ear syringing can improve hearing thresholds by 10dB or more in approximately 34% of patients 4
• Explain that common symptoms that may improve include: hearing on the phone, relief from pain, reduced sensation of blocked ears, and improved one-to-one hearing 4
• Note that pre-instillation of water for 15 minutes before syringing can significantly reduce the number of irrigation attempts needed (7.5 vs 25.4 attempts) 5

Potential Risks and Complications

• Advise that minor complications occur in approximately 38% of cases but are usually self-limiting 1
• Inform patients about common complications including:
  • Pain or discomfort during or after the procedure 1
  • Injury to the ear canal skin with or without bleeding 1
  • Tinnitus (ringing in the ears) 1
  • Vertigo (dizziness) - occurs in approximately 0.2% of cases 1, 3
  • Otitis externa (ear canal infection) 1
  • Otitis media (middle ear infection) if water enters the middle ear 1
• Explain that serious complications are rare but include tympanic membrane perforation (eardrum rupture) in approximately 0.2% of cases 1, 3
• Inform that major complications requiring specialist referral occur in approximately 1 in 1000 ear syringings 1, 6, 7

Contraindications

• Clearly state that ear syringing should not be performed in patients with:
  • History of tympanic membrane perforation 1
  • Previous ear surgery (as the eardrum may be thinned or atrophic) 1
  • Current ear infection or active dermatitis 1
  • Presence of tympanostomy tubes (grommets) 2
  • Narrow or stenotic ear canals 2
• Explain that special caution is needed for patients with diabetes due to higher risk of malignant otitis externa, particularly when using tap water 1

Aftercare Instructions

• Advise patients with diabetes to promptly report any ear discharge or ear pain following the procedure 1
• Suggest consideration of reacidifying the ear canal after irrigation to maintain the protective acidic pH 1
• Instruct patients to avoid inserting cotton-tipped swabs into the ear canal as they can push wax deeper 2
• Inform patients that if excessive earwax remains after the procedure, they should return for reassessment 8
• Advise patients to seek medical attention if they experience persistent pain, discharge, hearing loss, or dizziness after the procedure 8

Alternative Options

• Discuss alternative methods of cerumen removal if syringing is contraindicated or unsuccessful after multiple attempts 3
• Explain that manual removal using specialized instruments may be considered in certain cases 1
• Inform that cerumenolytic agents alone may be sufficient for some patients 1

Consent Process

• Ensure patients understand the procedure and have an opportunity to ask questions 1
• Document the informed consent discussion, including benefits, risks, and alternatives explained 1
• For children under 12 years, emphasize that a doctor should be consulted before performing ear syringing 8
