## **Hearing Loss Prevention Across the Lifespan: Evidence-Based Strategies for Clinical Practice**

(Original title: “Otological prevention—the key to lifelong hearing health”, Krumpoeck P. E. et al., HNO, 2026)

### **Otological prevention – the key facts at a glance:**

- Targeted preventive measures at every stage of life can often prevent hearing loss or significantly reduce its impact.
- ENT (ear, nose, and throat) practices play a central role in this process, from counseling and early detection to treatment.

## **Background: How common is hearing loss – and what can be done about it?**

Hearing loss affects around 1.5 billion people worldwide and has far-reaching consequences for communication and overall health. A substantial proportion of cases is potentially avoidable through systematic preventive interventions.

## **Objective**

To provide an overview of evidence-based strategies for preventing hearing loss across all stages of life and translate them into practical recommendations.

## **Methods**

Narrative review based on current clinical guidelines, systematic reviews, and epidemiological and clinical studies.

## **Key findings**

### **1. Pre- and perinatal prevention**

- Maternal immunization (e.g. MMR) significantly reduces the incidence of congenital infections associated with sensorineural hearing loss
- Cytomegalovirus (CMV) is the leading non-genetic cause of congenital hearing loss

- Early virological diagnosis (within 21 days postpartum) is critical for therapeutic decision-making and follow-up

### **2. Early detection in infancy**

- Universal newborn hearing screening (UNHS) constitutes diagnostic standard
- Adherence to “1–3–6” protocol for improved outcomes: screening ≤1 month, diagnosis ≤3 months, intervention ≤6 months
- Early intervention, including cochlear implantation when indicated, for better outcomes

### **3. Vaccination**

- Routine immunization effectively prevents hearing loss secondary to viral and bacterial infections
- Key pathogens include measles, mumps, Haemophilus influenzae type B, Streptococcus pneumoniae, and Neisseria meningitidis

### **4. Prevention in adulthood**

- Chronic noise exposure remains a leading modifiable risk factor in professional and leisure settings. Preventive measures include hearing protection.
- Ototoxicity (e.g. chemotherapy), requires risk-benefit assessment and audiological monitoring
- Modifiable lifestyle factors:
    – Smoking
    – Excessive alcohol consumption
    – Cardiometabolic risk profile

### **5. Auditory rehabilitation**

- Early intervention with hearing aids or hearing implants:
    – improves communication outcomes
    – reduces psychosocial comorbidity
    – mitigates cognitive deterioration

## **Clinical relevance**

- Prevention should be considered a lifelong process
- Early detection and timely intervention are crucial
- Counseling on hearing protection and lifestyle should be part of routine care
- Hearing rehabilitation significantly supports overall health and quality of life
