DISE - Drug Induced Sleep Endoscopy

 

DISE (Drug Induced Sleep Endoscopy)

When a patient presents with snoring to our clinic we first advise a complete sleep study (Polysomnography). This is either done in the medical facility or sometimes can be done at home as well (domiciliary sleep study). Once a sleep study confirms OSAS - Obstructive Sleep Apnoea Syndrome - we have to give the patient treatment options.

The commonest treatment option is to ask the patient to use a CPAP machine. Many patients have claustrophobia and for this or other reasons (travel a lot, sleep on their tummy) cannot or do not want to use the CPAP machine. These patients are candidates for surgery. Snoring is a multifactorial problem and the obstruction could be variably placed - either in the Nose, Nasopharynx, behind the palate (retropalatal), behind the tongue (Retroglossal) or in the hypopharynx/ larynx. Surgeries are carefully tailored to correct obstructions/ narrowing in these areas. In order to guide the surgeon as to which surgery would be beneficial for a particular patient we perform DISE - drug induced sleep endoscopy.

In DISE the patient is sedated to achieve a state of natural sleep. A Flexible Laryngoscope is then introduced and areas of obstruction identified. Based on these observations specific surgical procedures are recommended. DISE is a safe procedure and the patient is sent back in a short while - like a day care procedure.

Navigating Winter Health: A Comprehensive Guide for the Elderly

Image
As the winter season descends upon us, the risk of winter-related illnesses, especially among the elderly, becomes more pronounced. Understanding the causes and adopting preventive measures is crucial to ensure a healthy winter. The onset of winter often brings an increase in Upper Respiratory and Lower Respiratory tract infections, attributed to factors such as poor air quality, seasonal transitions, the emergence of winter viruses, and the chilling temperatures. 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. Layered Clothing: Dressing warmly with layered clothing is essential. Pay attention to warm innerw

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. Turbinoplasty - Benefits and Risks Benefits of Turbinoplasty Surgery: Improved Breathing: Turbinoplasty can significantly enhance nasal airflow, leading to better breathing and reduced nasal congestion.

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
