Overview

Laryngitis is the inflammation of the vocal engine house (larynx) due to over usage, irritation and infections from environmental and microbial sources. In most cases, it resolves on its own within one week. The occurrence of laryngitis causes hoarseness and loss of voice. The larynx plays an important role in breathing, swallowing and voice processing. The larynx functionality over time is affected by age, diseases, hormones and medications 1. The laryngitis can be acute or chronic, depending on the clinical presentation of the disease. The elderly population of those with laryngitis is sporadically increasing yearly. In the year 2020, the elderly population accounted for 18.35% of the total population in developed nations, and this percentage rises annually and in 2050 is expected to reach 24.66%.

Clinical signs and symptoms of laryngitis   

The signs and symptoms of the disease condition include:

• Hoarseness
• Sore throat
• Difficulty speaking
• Irritating cough
• A constant need to clear the throat  
• Mild fever
• Tickling sensation and throat rawness 

It is worth noting that laryngitis is often associated with other illnesses like flu, cold, tonsillitis or throat infection, so you might see the following symptoms:

• Running nose
• Headache
• Feeling weak and achy
• Swollen glands
• Pain when swallowing

Etiology and risk factors of laryngitis in elderly patients

The root cause of laryngitis can be acute or chronic, depending on the severity of the illness. Acute laryngitis is temporary and does not last long once the underlying factors have been treated, compared with the chronic type. and its causes include the following:

• Viral infections like the cold and influenza
• Bacterial infections, although they are less common
• Hormonal changes due to ageing
• Overuse of the vocal cords causes voice strain
• Odynophonia (pain with voice usage)
• Swallowing problems
• Shortness of breath

Chronic laryngitis lasts more than three weeks and is often caused by exposure to irritants and other predisposing factors such as

• Smoking
• Pollutants like chemical fumes, allergens
• Overuse of the voice causes voice injuries
• Gastroesophageal reflux disease (GERD) causes acid reflux
• Excessive alcohol intake
• Chronic sinusitis

Other causes include:

• Cancer
• Bowing of the voice cords
• Voice cord paralysis, which might be from nerve injury because of surgery, wound to the neck or chest, cancer, nerve disorders, or other health conditions 

Risk factors

The age-related risk factors involved in laryngitis include:

• Weakened immune system
• Respiratory functions and infections such as chronic lung disease, cough, cold, bronchitis, sinusitis • Overuse of voice in shouting, singing or talking loudly
• Use of medications that suppress immunity or dry out the mucus membranes

Potential complications of laryngitis in elderly patients

• Chronic laryngitis: persistent inflammation leading to long-term hoarseness, voice strain or injury to vocal cords.
• Respiratory complications: Elevated risk of airway obstruction because of swelling, which may worsen the existing respiratory or pulmonary conditions, such as COPD or asthma. Additionally, there may be a risk of aspiration because of difficulty in swallowing, leading to aspiration pneumonia
• Secondary infections: There is a potential risk of developing secondary bacterial infections like bronchitis, pneumonia because of a weakened immune system.
• Difficulty swallowing: Laryngitis can impair the muscles involved in swallowing, increasing the risk of malnutrition or dehydration
• Communication difficulties: Voice hoarseness or loss can lead to social isolation, frustration, and emotional distress, especially in elderly patients who already have sensory impairments like hearing loss
• Impact on quality of life: Laryngitis can decrease the ability to communicate, causing frustration and anxiety in elderly patients who may already struggle with other age-related conditions

Special considerations in management and treatment for elderly patients

• Challenges in diagnosis: Overlap of symptoms with other age-related conditions like Chronic obstructive pulmonary disease and GERD
• Medication management: Potential complications such as side effects, adverse effects, and drug interactions. Furthermore, the use of steroids and other treatments must be taken with caution in elderly populations
• Preventive measures: Giving immunisation to prevent influenza, pneumococcal infections. Additionally, lifestyle modifications like stopping smoking, managing GERD should be encouraged

Treatment options

• Medical therapy: Treatment of the underlying cause of the illness, taking good nutrition and physical exercise to improve the muscle function, increase lung capacity and reduce the cardiovascular risk. This invariably improves the quality of life
• Hormonal replacement therapy: This may be an option in patients with vocal changes because of menopause       
• Surgery: This is considered in patients with cancer or people who have not benefited from vocal treatment and have a benign vocal mass or glottic insufficiency because of paralysis. This is vital after necessary medical investigation and diagnosis have been carried out, and it should be considered as the first line of treatment for the illness

Summary

Laryngitis is the inflammation of the larynx, often causing hoarseness, voice loss, sore throat, and difficulty speaking. In elderly patients, it can be acute or chronic, with increased vulnerability due to age-related factors like weakened immunity, vocal strain, and underlying conditions (e.g., GERD, chronic lung disease). Common causes include viral infections, smoking, acid reflux, and environmental irritants.

Potential complications in the elderly include chronic laryngitis, respiratory obstruction, aspiration pneumonia, secondary infections, swallowing difficulties, and social or emotional challenges due to impaired communication.

Management considerations involve careful diagnosis due to overlapping conditions, cautious medication use, and preventive strategies like vaccination and lifestyle changes. Treatments include addressing the root cause, voice therapy, hormonal therapy in menopausal women, and surgery in severe or cancer-related cases.
