From the Guidelines

The management of chronic bilateral otomastoiditis requires a comprehensive approach combining medical therapy and potential surgical intervention, with the goal of reducing morbidity, mortality, and improving quality of life.

Initial Management

Initial treatment typically involves a course of culture-directed antibiotics, often including fluoroquinolones like ciprofloxacin (500mg twice daily for 10-14 days) or amoxicillin-clavulanate (875mg/125mg twice daily for 10-14 days) 1.

  • Topical antibiotic ear drops containing ciprofloxacin with or without dexamethasone should be administered 3-4 drops twice daily for 7-10 days to address local infection.
  • Careful aural toilet with gentle suctioning and debridement of debris is essential for effective medication penetration.

Surgical Intervention

For patients with persistent symptoms despite medical therapy, surgical intervention may be necessary, with tympanomastoidectomy being the most common procedure to remove diseased tissue and establish drainage 1.

  • The decision to perform surgery should be based on the presence of symptoms attributable to otitis media, such as hearing difficulties, balance problems, or reduced quality of life.

Long-term Management

Long-term management includes:

  • Regular follow-up every 3-6 months to monitor for recurrence or progression of disease.
  • Keeping ears dry during bathing or swimming using earplugs or cotton balls with petroleum jelly to prevent water entry and reduce the risk of infection.
  • Prompt treatment of upper respiratory infections to prevent recurrence of otitis media.

This approach addresses both the infectious component through antimicrobials and the structural issues through cleaning and possible surgery, targeting the underlying pathophysiology of chronic inflammation and infection in the middle ear and mastoid air cells 1.

From the FDA Drug Label

The recommended dosage regimen for the treatment of chronic suppurative otitis media with perforated tympanic membranes in patients 12 years and older is: Ten drops (0.5 mL, 1. 5 mg ofloxacin) instilled into the affected ear twice daily for fourteen days.

The management approach for chronic bilateral otomastoiditis is not directly addressed in the provided drug labels. However, for chronic suppurative otitis media with perforated tympanic membranes, the recommended treatment is ofloxacin otic solution.

  • For patients 12 years and older:
    • Ten drops (0.5 mL, 1.5 mg ofloxacin)
    • Instilled into the affected ear twice daily for fourteen days
    • The solution should be warmed by holding the bottle in the hand for one or two minutes to avoid dizziness that may result from the instillation of a cold solution.
    • The patient should lie with the affected ear upward, before instilling the drops
    • The tragus should then be pumped 4 times by pushing inward to facilitate penetration into the middle ear.
    • This position should be maintained for five minutes.
    • Repeat, if necessary, for the opposite ear 2.

Note that chronic bilateral otomastoiditis may require a different approach, and these instructions are for chronic suppurative otitis media. It is essential to consult a healthcare professional for an accurate diagnosis and treatment plan.

From the Research

Management Approach for Chronic Bilateral Otomastoiditis

The management of chronic bilateral otomastoiditis involves a comprehensive approach that includes:

  • Early diagnosis and treatment to prevent long-term complications 3
  • Antibiotic stewardship to address antibiotic resistance patterns, particularly for Streptococcus pneumoniae and Staphylococcus aureus 3
  • Targeted surgical interventions, such as mastoidectomy, to manage the condition and prevent further complications 3, 4
  • Aggressive antibiotic therapy and a low threshold for conservative operative intervention to resolve infection and preserve implants in patients with cochlear implants 4
  • Surgery combined with antibiotic therapy for refractory otomastoiditis due to nontuberculous mycobacteria 5
  • Combined endoscopic transmastoid and transsphenoidal debridement for central skull base osteomyelitis, a rare complication of chronic otitis media 6

Key Considerations

  • Healthcare accessibility and antibiotic resistance are significant factors influencing the management of chronic otomastoiditis 3
  • Early operative drainage and aggressive antibiotic therapy are crucial in managing mastoiditis in children with cochlear implants 4
  • NTM otomastoiditis should be suspected in patients with chronic refractory otorrhea and ear granulation tissue, and treatment should involve surgery and antibiotics 5
  • Central skull base osteomyelitis poses significant management challenges, requiring complex surgical intervention and culture-directed antibiotic therapy 6

Treatment Strategies

  • Surgical interventions, such as mastoidectomy and debridement, play a critical role in managing chronic bilateral otomastoiditis 3, 4, 5, 6
  • Antibiotic therapy should be tailored to address specific pathogens and resistance patterns 3, 4, 5, 6
  • Combined treatment approaches, including surgery and antibiotics, may be necessary to manage complex cases of chronic bilateral otomastoiditis 3, 4, 5, 6
