Herpes zoster oticus (or, as it is also called, herpetic otitis) is an infectious disease resulting from the reactivation of the Varicella-Zoster virus (VZV), which causes chickenpox. This condition is characterized by acute damage to the auditory and vestibular apparatus, and also manifests itself in the form of pain syndrome, skin rashes and possible development of neurological symptoms. Herpes zoster oticus can be accompanied by a number of severe complications, especially in patients with a weakened immune response, which makes it an important subject of medical research and practice.
History of the disease and interesting historical facts
Herpes zoster has a long history, dating back to ancient times. The first mentions of chickenpox and its associated symptoms can be found in the works of ancient Greek and Roman doctors. However, it was only at the end of the 19th century, thanks to research, that the causes and mechanisms of the disease associated with the Varicella-Zoster virus became known. An interesting fact is that as early as the 1920s, cases of herpes zoster associated with it were registered in patients who had chickenpox in childhood.
Epidemiology
Herpes zoster is highly prevalent worldwide. According to statistics, approximately 30% people will encounter this infection at least once during their lifetime. It is important to note that the incidence increases with age, reaching 50% in elderly patients over 85 years of age. In addition, the disease is more common in people with a weakened immune response, such as patients with HIV, cancer, or after immunosuppressive therapy.
Genetic predisposition to this disease
Research suggests that genetic predisposition may play a significant role in the development of herpes zoster oticus. Some studies point to the involvement of genes responsible for the immune response, such as the HLA type, as well as mutations in genes associated with T-lymphocyte function. In particular, the HLA-DR and HLA-DQ genes have been associated with an increased risk of developing the disease.
Risk factors for the development of this disease
The following risk factors influence the quality and frequency of occurrence of herpes zoster:
- Age: over 50 years old
- Immunodeficiency states (HIV, blood diseases, immunosuppressant therapy)
- Presence of stress
- Chronic diseases (diabetes, lung and heart disease)
- Descending hereditary factors
These factors make patients more vulnerable and may initiate viral reactivation.
Diagnosis of this disease
Diagnosis of herpes zoster oticus involves several aspects.
- Main symptoms: Pain in the ear area, blistering rashes, itching and hearing loss.
- Laboratory tests: Virological tests for the presence of Varicella-Zoster virus in fluid samples from vesicles.
- Radiological examinations: Magnetic resonance imaging for the assessment of inflammatory processes.
- Other types of diagnostics: Consultations with an otolaryngologist and neurologist.
- Differential diagnosis: It is necessary to exclude other forms of otitis and infections.
Treatment
Treatment of herpes zoster oticus can be either medicinal or surgical.
- General treatment: Provide rest and prescribe antihistamines to reduce itching.
- Pharmacological treatment: Antiviral drugs (eg, acyclovir, valacyclovir) to suppress viral activity.
- Surgical treatment: In rare cases, drainage is required when conservative methods are ineffective.
- Other types of treatment: Physiotherapy and immunostimulants to restore hearing function and improve the condition.
List of medications used to treat this disease
Medicines for the treatment of herpes zoster oticus include:
- Acyclovir
- Valaciclovir
- Ganciclovir
- Prednisolone (if needed)
- Painkillers (paracetamol, ibuprofen)
Disease monitoring
Monitoring the patient's condition is important to prevent possible complications such as neuritis, hearing loss, and others. Control stages include:
- Regular check-ups with a specialist
- Monitoring of auditory functions
- Prevention of possible relapses by vaccination against chickenpox
The prognosis is favorable in most cases with timely treatment, but complications may develop, which requires additional medical intervention.
Age-related features of the disease
Herpes zoster oticus is more common in older people, which is associated with age-related changes in the immune system. In young people and children, the disease occurs in a milder form, while older patients may experience more severe symptoms and frequent relapses.

Advice from Dr. Oleg Korzhikov
Doctor Oleg Korzhikov recommends not to delay seeing a doctor at the first symptoms of the disease. The main recommendations include:
- If painful rashes or hearing problems occur, consult a doctor immediately.
- Monitor your health, especially if you already have chronic diseases.
- Don't forget about vaccination, it can be a preventive measure.
