From the Guidelines
Herpes zoster on the auricle requires prompt antiviral treatment with oral medications such as valacyclovir 1000 mg three times daily, famciclovir 500 mg three times daily, or acyclovir 800 mg five times daily for 7-10 days, as recommended by the most recent guidelines 1. When considering treatment options, it's essential to prioritize the most recent and highest quality study, which in this case is from 2014 1. However, it's also important to note that more recent studies, such as the 2024 recommendations for herpes zoster vaccination for adults in Taiwan 2, may provide additional guidance on prevention and management.
Key Considerations
- Treatment should begin within 72 hours of rash onset for maximum effectiveness
- Pain management is essential and may include acetaminophen, NSAIDs, or in severe cases, gabapentin or pregabalin
- Topical treatments like calamine lotion can help soothe the rash
- When herpes zoster affects the ear (Ramsay Hunt syndrome), it can cause facial paralysis, hearing loss, and vertigo, requiring urgent evaluation
Prevention and Complications
- The condition results from reactivation of the varicella-zoster virus that remained dormant in sensory ganglia after chickenpox infection
- Complications may include postherpetic neuralgia (persistent pain after rash healing), which is more common in older adults, so early aggressive treatment is particularly important in patients over 50
- Vaccination is the most effective strategy to prevent varicella, HZ, and its related complications, as recommended by the 2024 study 2
Patient Care
- Patients should keep the affected area clean and avoid touching or scratching lesions to prevent secondary bacterial infection and transmission
- A complete head and neck examination with visualization of the mucosal surfaces of the head and neck, assessment of any neck masses, and palpation of the tongue base is recommended to rule out other potential etiologies of otalgia 1
From the Research
Herpes Zoster on Auricle
- Herpes zoster, also known as shingles, is a viral infection caused by the varicella-zoster virus, which is the same virus that causes chickenpox 3.
- The virus can reactivate later in life, typically in people over 50 years old, and cause a painful rash on one side of the body, including the auricle (outer ear) 4.
- Antiviral medications such as valaciclovir, aciclovir, and famciclovir are effective in treating herpes zoster and reducing the risk of postherpetic neuralgia (PHN), a common complication of the disease 3, 5, 6, 7.
Treatment Options
- Valaciclovir has been shown to be at least as effective as aciclovir in controlling the symptoms of acute herpes zoster and alleviating zoster-associated pain and PHN 3.
- Famciclovir has also been shown to be effective in reducing the risk of PHN and shortening the duration of zoster-associated pain 5, 7.
- The American Academy of Ophthalmology recommends the use of antiviral medications such as valaciclovir, aciclovir, and famciclovir for the treatment of herpes zoster, including ophthalmicus (eye involvement) 4.
Management of Pain
- Pain management is an important aspect of treating herpes zoster, as the disease can cause significant discomfort and PHN can be debilitating 4.
- Antiviral medications can help reduce the risk of PHN, but other treatments such as tricyclic antidepressants, antiseizure drugs, opioids, and topical analgesics may also be necessary to manage pain 4.
- Prevention of herpes zoster through vaccination is also an important consideration, especially for older adults who are at higher risk of developing the disease 4.
