Endoscopic Sinus Surgery
Endoscopic sinus surgery is for sinus problems that medication hasn't or can't resolve, such as chronic blockages, recurrent infections, or both. The surgery is done entirely through the nostrils. No external incisions, no visible scarring. A high-definition endoscope gives the surgeon a clear view of the sinus cavities, and navigation systems help work around the more complex areas of the anatomy safely.
At Aster Hospitals UAE, we specialise in utilising high-definition endoscopic techniques to restore normal sinus physiology without external incisions. Moreover, the surgery addresses the structural problem rather than the symptoms sitting on top of it.
Functional endoscopic sinus surgery or FESS targets the root of the problem: blocked sinus openings that stop the sinuses from draining properly. The surgeon works through the nostrils using a rigid endoscope, a thin illuminated tube with a camera at the tip. It gives a magnified, close-up view of the sinus anatomy, which makes it possible to remove obstructive tissue precisely without cutting from the outside.
The goal is drainage. When the sinuses can't clear themselves, infection and inflammation keep coming back, regardless of how many rounds of antibiotics a patient goes through. FESS reopens those pathways, which is why the results tend to last in a way that medication alone usually doesn't.
We employ this surgical technique to manage a spectrum of pathologies that compromise sinus health.
Surgery comes after everything else has been tried. Most patients who reach this point have already been through multiple courses of antibiotics, steroid sprays, and antihistamines, sometimes over a year or more. The threshold is roughly twelve weeks of persistent symptoms despite that kind of treatment, or recurrent infections that keep knocking people off their feet every few months.
A CT scan adds another layer to the decision for otolaryngologists. If it shows a clear structural blockage or an anatomical problem, a narrow drainage pathway, or a deviated septum pressing against the sinus opening, medication was never going to fix that. Surgery becomes less of an option and more of the logical next step.
The sinus endoscopic surgery process mirrors the precision of laparoscopic procedures, utilising natural orifices to access internal structures.
Anaesthesia: We administer general anaesthesia to ensure patient comfort and immobility.
Endoscope Insertion: The surgeon gently guides the endoscope through the nostrils to visualise the nasal cavity.
Removal of Blockages: Using micro-instruments, the surgeon meticulously removes polyps, scar tissue, or infected material.
Opening Drainage Pathways: We widen the natural openings of the sinuses to facilitate mucus drainage.
No External Cuts: The entire procedure occurs intranasally, leaving no external scars.
Short Observation Period: Medical staff monitors the patient for a few hours post-surgery before discharge.
Functional endoscopic sinus surgery offers significant advantages over traditional open approaches. Patients benefit from the absence of external scars, as the procedure leaves no facial incisions. The technique results in less pain and minimal bleeding compared to older methods. Faster healing allows a swift return to daily activities. Critically, the surgery improves airflow and significantly reduces the frequency and severity of infection episodes.
The endoscopic sinus surgery cost varies based on several factors. The cost depends on the sinus condition severity, required diagnostic tests, anaesthesia fees, and the specific surgical technique employed. A clear estimate is shared after a thorough evaluation and consultation with the surgical team.
Aster Hospitals is recognised as the Best ENT hospital in Dubai, committed to excellence in patient care. Our team includes highly skilled ENT surgeons who specialise in complex sinus anatomy. We utilise advanced endoscopic equipment and precise imaging navigation systems to enhance surgical accuracy.
Individuals seeking the best endoscopic sinus surgery in Dubai choose us for our faster recovery protocols and high success rates. If you require a trusted ENT doctor in Dubai, our specialists provide comprehensive care across the city, including Mankhool, Al Qusais, Jebel Ali, and Muhaisnah.
Our ENT department consists of board-certified otolaryngologists in Dubai, with a focused background in rhinology and sinus surgery. They work on the full spectrum, routine FESS cases and more involved reconstructions where the anatomy is complicated or a previous surgery needs to be revisited. The plan for each patient is built from their CT findings and symptom history. That detail matters more than a generalised protocol.
It is a minimally invasive procedure using an endoscope to unblock sinuses and restore natural drainage without external incisions.
Patients with chronic sinusitis unresponsive to medication, nasal polyps, or recurrent sinus infections are prime candidates.
A detailed history, nasal endoscopy, and a CT scan confirming obstruction will determine your candidacy.
Patients typically experience minimal pain due to the minimally invasive nature, which is managed easily with prescribed analgesics.
