Why previous sinus surgery sometimes fails, and what can be done

For many patients, sinus surgery provides significant relief from long-standing symptoms such as nasal blockage, facial pressure, and recurrent infections. However, a proportion of patients continue to experience symptoms even after surgery.

This can be both frustrating and confusing, particularly when surgery was expected to resolve the problem. Understanding why this happens is an important step in determining what can be done next.

Why Do Symptoms Persist After Sinus Surgery?

Sinus disease is often complex and can affect multiple sinus cavities at the same time. In some cases, symptoms persist because the underlying disease process has not been fully addressed.

Common reasons include:

• Ongoing inflammation within the sinuses

• Recurrent or persistent nasal polyps

• Incomplete or limited opening of sinus drainage pathways

• Scarring or narrowing after previous surgery

• Failure to comply with ongoing long-term intranasal corticosteroids use to control the inflammatory disease 

The Importance of Complete Sinus Surgery

Successful sinus surgery is not simply about removing tissue. The goal is to restore natural drainage and ventilation across all sinuses then allow for topical medical therapies to control the inflammation long-term.

Increasingly, evidence is supporting the importance of complete sinus ventilation, whereby patients who have all their sinuses completely opened have better outcomes to those with limited surgery. This is why it is important to identify a surgeon who has the expertise to open all sinuses adequately, reducing the chances of needing further repeat surgery.

When to Consider Revision Sinus Surgery

If symptoms continue after previous surgery, a detailed reassessment is important. This may involve:

• Nasal endoscopy

• CT imaging

• Review of previous treatment

Revision sinus surgery may be recommended when there is clear evidence that persistent disease or incomplete drainage is contributing to symptoms. More recently, CT based grading systems have been developed that assess the extent of previous sinus surgery that had been performed. This helps give patients and clinicians an understanding of whether further revision surgery will be beneficial. 

A Specialist Approach to Complex Cases

Patients with ongoing symptoms after sinus surgery often benefit from specialist assessment. This allows for:

• Detailed evaluation of sinus anatomy

• Identification of untreated areas

• Consideration of surgical and non-surgical options

Frequently Asked Questions

Why does sinus surgery sometimes fail?

Sinus surgery may not fully resolve symptoms for 3 main reasons:

1. Surgical factors - sinus cavities incompletely opened 

2. Patient factors - failure to continue with topical nasal steroids

3. Disease factors - patients have a severe degree of inflammation which may require further newer novel agents such as Biologics. 

What is revision sinus surgery?

Revision sinus surgery is a procedure performed to address ongoing sinus disease after a previous operation to give the maximal improvement in symptoms for the longest period of time.

Can symptoms improve after a second surgery?

Yes, many patients experience significant improvement when the underlying cause is properly identified and treated. This is often due to incomplete or conservative procedures that have been performed previously.

Is the frontal sinus important in surgery?

Yes, the frontal sinus is just like every other sinus and is affected in the same way. Complete comprehensive sinus surgery involves ventilation of all sinuses including the frontal sinus. Frontal sinus surgery requires a specific skill set and can be challenging which is why it is commonly not addressed during routine sinus surgery. A lot of Mr Jolly's practice involves helping patients who have had multiple previous operations. In these cases the aim is to ventilate all sinuses not previously addressed and this commonly includes the frontal sinus.

Book a Consultation

If you are still experiencing symptoms after previous sinus surgery, a consultation with Mr Karan Jolly can help determine the cause and explore appropriate treatment options.
