Vertigo Testing - How Is It Done?

Vertigo, Dizziness, Giddiness, Imbalance are complex related symptoms that can trouble the patient as well as confound and confuse the clinician trying to make sense of it.
Vertigo is typically the sensation that the world around you is spinning or sometimes that the world around you is steady but you are spinning around.
The imbalance is usually a different symptom in which there is a sense of swaying to one side, loss of confidence in walking, especially on unsteady surfaces or at night.
There are many causes of true vertigo - from BPPV (Benign Paroxysmal Positional Vertigo), Meniere's Disease, Vestibular Neuritis, Labyrinthitis, Migraine associated Vertigo, Drug-induced Vertigo etc. 
One of the most critical aspects in diagnosing a patient with Vertigo is to take a thorough history of the Vertigo itself- When does it occur, what precipitates it, how long does it last, what makes it better, is there accompanying nausea/ vomiting, is it accompanied with headache/s etc - each one leading to a specific cause and diagnosis.
 For an accurate diagnosis, the patient is then subjected to a series of complex tests that assist the clinician in reaching a conclusion.
The following tests are carried out 
  • Craniocorpography - checking for VestibuloSpinal reflex
  • Advanced VNG- Vestibularnystagmography - The equipment evaluates peripheral and central vestibular functions using 10 protocols. It is the most advanced technology for oculomotor  & positional tests
  • Caloric Test - now a thermal test - we are not using water caloric
  • Visual Head Impulse Test - testing the semicircular canals
  • Subjective Visual Vertical - for abnormal subjective tilt
  • Dynamic Visual acuity - It assesses the ability of the subject to maintain the image on the fovea of the retina during head movement, an important function of Vestibulo Ocular Reflex (VOR).
Once the tests are carried out a cloud-based platform checks the results against laid out Algorithms to reach a tentative diagnosis.
This is then vetted by a trained team of a Senior ENT Specialist trained on Vertigo management as well as a Neurologist. 
A final diagnosis is arrived at and a course of action which could include medication, as well as rehabilitative manoeuvres and exercises, are explained.

Turbinoplasty Surgery - explained by Dr. Rajesh Bhardwaj

Image
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. MedFirst ENT Centre, located in Delhi, India, offers top-quality turbinoplasty surgery performed by highly skilled ENT surgeon and their professional medical team.
