Otitis Externa - Explained By Dr. Rajesh Bhardwaj


Otitis externa, also called swimmer’s ear, is inflammation of the ear canal. It often presents with ear pain, swelling of the ear canal, and occasionally decreased hearing.Typically there is pain on movement of the outer ear or on touching the ear.

Otitis externa may be acute (lasting less than six weeks) or chronic (lasting more than three months).

 Acute cases are typically due to bacterial infection, and chronic cases are often due to allergies and autoimmune disorders.The most common cause of Otitis externa is bacterial. Risk factors for acute cases include swimming, minor trauma from cleaning, using hearing aids and ear plugs, and other skin problems, such as seborrhoea (dandruff), psoriasis and dermatitis.

People with diabetes are at risk of a severe form of disease called malignant otitis externa. This disease causes progressive destruction of external ear tissues and can spread deep inside the ear. Diagnosis is based on the signs and symptoms.Culturing the ear canal may be useful in chronic or severe cases. Pain is severe and is usually indicative of an active disease. Controlling the blood sugar and giving prolonged appropriate antibiotics is the treatment of choice.

The current scenario highlights a significant prevalence of these respiratory infections, with the elderly population, particularly those with underlying health conditions, such as diabetes, being more susceptible. Safeguarding against winter illnesses involves a combination of proactive steps: Vaccination: Ensure you have received your flu vaccine, providing added protection against prevalent winter viruses.

Turbinoplasty Surgery - explained by Dr. Rajesh Bhardwaj

Turbinoplasty Surgery Turbinoplasty is a surgical procedure aimed at addressing nasal congestion and breathing difficulties caused by enlarged turbinates. The turbinates are bony structures covered in soft tissue located inside the nose, responsible for filtering, warming, and humidifying the air we breathe. When the turbinates become swollen due to allergies, chronic sinusitis, or other nasal conditions, it can lead to nasal obstruction and reduced airflow. Turbinoplasty involves the reduction or repositioning of the turbinates to improve nasal airflow and alleviate breathing problems.

Testing for Vertigo and Balance Disorder

Image
Vertigo, Dizziness, Giddiness are common symptoms that are poorly understood by the patient as well as physicians. It has been my experience that patients who suffer from a sudden episode of Vertigo reach the emergency unit of hospitals where they are admitted and subjected to a whole range of investigations, including a cardiac evaluation and an MRI of the brain. After a few days, the patient is discharged without reaching a conclusive diagnosis. It is well known that sudden episodes of Vertigo that incapacitate a patient usually arise out of an Ear pathology.  The cause has to be determined. For a patient suffering from Giddiness , a detailed history is very important - when do the giddy spells happen,  how long do they last,  any accompanying symptoms like nausea, vomiting, headache, or visual disturbances, what precipitates the attack - like turning in bed, going out in the hot sun, after a period of viral infection?   what medicine do you take to make it better? For patients in w
