Brief Answer: Transmission of pressure/ infection to inner ear Detailed Answer: Hello XXXX, Thanks for your query. There is a connecting tract (known as Eustachian tube) between the nasopharynx & middle ear through which infection can spread to ear. Any obstruction to this Eustachian tube, secondary to an upper respiratory tract infection, Sinusitis, cold & congestion, causes un-equalisation of pressure between the nasopharynx & middle ear. This pressure change gets transmitted to the inner ear which has a specialized structure called Vestibular apparatus. The Vestibular apparatus plays an important role in maintaining the posture & body balance. Hence, a disturbance in this apparatus secondary to build up of pressure & spread of infection in ear causes dizziness. Investigations like complete blood count, X ray of the para nasal sinus, laryngoscopy & nasal endoscopy will be helpful in clinching the diagnosis. Management includes: 1. Antihistamine preparations like Allegra. 2. Decongestant nasal drops. 3. Antibiotics based on culture & sensitivity reports. 4. Warm salt water gargle. 5. Steam inhalation. 6. Maintenance of adequate hydration & nutrition status of the body. 7. Protection from cold, dust & other allergens. As the Sinusitis gets treated, the symptoms of dizziness & sensation of pressure in eyes & ears will automatically subside. Hope I have been able to answer your query. Please let me know if I need to clarify further. Wishing you a Good Health. Take care.
