Why would a sinus infection postpone surgery?

A sinus infection, also known as sinusitis, can potentially cause a surgeon to postpone an elective surgery for several reasons. Understanding why sinusitis may delay a surgical procedure can help patients prepare for potential changes to their surgery schedule.

What is sinusitis?

Sinusitis refers to inflammation and swelling of the sinuses. The sinuses are air-filled cavities located within the bones surrounding the nose. When the sinuses become inflamed and congested with mucus, it can interfere with normal sinus drainage and cause an infection.

There are two main types of sinusitis:

  • Acute sinusitis – Symptoms last less than 4 weeks
  • Chronic sinusitis – Persistent symptoms lasting more than 12 weeks

Common signs and symptoms of sinusitis include:

  • Facial pain and pressure
  • Nasal congestion and discharge
  • Loss of smell
  • Cough
  • Fatigue
  • Headache
  • Bad breath
  • Fever

How might sinusitis affect surgery?

There are a few reasons why sinusitis may cause a surgeon to delay elective surgery:

Concerns with anesthesia

Sinusitis causes inflammation and congestion in the nasal and sinus passages. This can make administration of general anesthesia more complex if endotracheal intubation is required.

Endotracheal intubation involves placing a breathing tube into the airway after the patient has been given anesthesia medications. A congested airway makes this process more difficult and risky.

The anesthesiologist may delay surgery until the sinus infection has cleared to allow for safer intubation of the airway.

Post-operative respiratory complications

Sinus congestion reduces normal mucus drainage. This can increase risks of respiratory complications after surgery.

General anesthesia and surgical procedures inhibit the cough reflex. Mucus buildup during surgery could lead to post-operative pneumonia, bronchitis, or other problems if the patient’s sinuses are already infected.

Surgeons may delay procedures to avoid subjecting patients to additional respiratory risks while recovering from surgery.

Concerns with sterility and infection risk

When the sinuses are inflamed and infected, there is greater risk of spreading infection to the surgical site or implanted medical devices.

Surgeons carefully prepare the skin and operating room to create a sterile surgical field. Active sinusitis creates an internal source of potential infection. This raises concerns about surgical wound infections or contamination of implants.

Delaying surgery until sinusitis has resolved helps diminish this contamination risk.

Need for antibiotics

Most cases of bacterial sinusitis require antibiotic treatment. Depending on the type and severity of infection, a doctor may prescribe antibiotics for 7-14 days before considering sinusitis resolved.

Undergoing surgery while still needing antibiotics raises concerns about effectiveness of treatment, risk of spreading infection, development of antibiotic-resistant organisms, and other issues.

Postponing an elective surgery allows antibiotics to properly treat the sinus infection before proceeding with the operation.

Impact on recovery and wound healing

Sinusitis causes generalized inflammation and puts stress on the body’s immune system. This can hinder the wound healing process after surgery.

Patients with active sinus infections may also suffer fatigue, discomfort, poor sleep quality, impaired breathing, and other issues during post-operative recovery.

Delaying non-urgent surgery until sinusitis has improved allows patients time to recover and regain health. This helps promote proper healing after surgical procedures.

How long might sinusitis delay surgery?

The amount of time a surgeon postpones surgery due to sinusitis can vary based on:

  • Severity of sinus infection symptoms
  • Whether the sinusitis is acute or chronic
  • Patient’s response to antibiotic treatment
  • Type of surgery required and associated risks

Mild acute sinusitis may only delay surgery by 1-2 weeks. More severe or chronic cases could result in postponing procedures for a month or longer.

The surgeon will reevaluate the patient’s condition after initial antibiotic treatment to determine if it is safe to proceed with surgery or if more delay is warranted.

How can sinusitis be treated before surgery?

To help resolve sinusitis sooner rather than later, surgeons may recommend:

  • Antibiotics – Prescribed if the sinusitis is bacterial in nature. Common options include amoxicillin, augmentin, cephalosporins, or fluoroquinolones.
  • Nasal steroids – Corticosteroid nasal sprays like Flonase help reduce sinus inflammation.
  • Nasal saline rinses – Rinsing the nasal passages helps clear mucus and soothe inflammation.
  • Decongestants – Oral or nasal decongestants reduce congestion but usually are not prescribed long-term.
  • Pain relievers – Ibuprofen, acetaminophen, or other nonsteroidal anti-inflammatory drugs can temporarily relieve sinus pain and pressure.
  • Allergy treatment – If allergies are contributing to sinusitis, preventing allergy flares may help.
  • Home remedies – Rest, hydration, steam inhalation, warm compresses, and sinus massage may provide symptom relief.

The patient should collaborate closely with their surgeon and primary care doctor to get the sinusitis under control prior to elective surgery. They may need to schedule sinus-related medical appointments to reevaluate readiness for surgery.

What if sinusitis persists long-term?

For chronic sinusitis cases that do not readily improve with conservative treatments, surgeons may consider additional interventions to try clearing the sinuses prior to surgery, including:

  • Extended antibiotic therapy – Higher antibiotic doses for longer treatment periods.
  • Culture-directed antibiotics – Choosing specific antibiotics based on culturing the sinus bacteria.
  • Nasal endoscopy – Using a tiny camera inside the nasal cavities to visualize the source of congestion.
  • Sinus surgery – Operatively opening the sinus drainage pathways.
  • Intravenous antibiotics – Powerful IV antibiotics for difficult-to-treat organisms.

In recalcitrant cases, the surgeon may opt to proceed with surgery despite sinusitis risks if delaying further would cause harm. Additional safety precautions are taken if operating with active sinusitis.

Can sinusitis arise right before surgery?

Unfortunately, it is possible for sinusitis to develop suddenly before the scheduled surgery date, even if the patient’s sinuses were clear upon initial pre-operative assessment.

Factors that could lead to eleventh-hour sinusitis include:

  • Recent cold or upper respiratory infection
  • Seasonal allergies flaring up
  • Weather changes affecting sinus function
  • Poor sleep or hydration weakening immune defenses
  • Stress compromising the immune system

Patients may experience mild congestion for days before sinusitis hits full force. Subtle symptoms are easy to dismiss or attribute to other causes. This allows sinus inflammation to progress quietly in the background before becoming significant enough to affect surgical plans.

Sudden onset sinusitis can be extremely frustrating after weeks or months of surgical anticipations. But postponing procedures at the last minute is necessary to prevent dangerous anesthesia reactions or post-operative complications.

How can same-day sinusitis be detected before surgery?

On the morning of surgery, patients should proactively mention even minor sinus or respiratory symptoms to their surgical team, such as:

  • Mild nasal stuffiness or discharge
  • Low-grade headache
  • Mild facial pressure
  • Recent cold symptoms
  • Allergy flare up
  • Runny nose
  • Sneezing or coughing

The anesthesiologist will examine the patient’s breathing and sinuses. They may ask about:

  • Color and consistency of nasal discharge
  • Sinus pain history
  • Recent illness duration
  • Current allergy symptoms

If the anesthesiologist has concerns, they will obtain a CT scan to visualize the sinuses or cultures to identify any bacterial infection.

Last minute sinusitis may still force postponement of surgery to allow proper treatment. But the sooner it is caught, the less time the patient must wait until the procedure can be rescheduled.

What risks come with postponing surgery?

Delaying any surgery carries certain risks, including:

  • Progression of underlying condition
  • Ongoing pain, limited function, or disability
  • Mental and emotional stress of anticipation
  • Potential need for additional tests or clinical interventions

Specifically for sinusitis postponements, additional concerns include:

  • Need for repeat pre-operative testing after sinusitis resolves
  • Persistence or recurrence of sinus infections
  • Rarely, decline in health could make patient unfit for surgery

However, proceeding with surgery while sinusitis is active carries far greater operative and post-operative risks. A thoughtful delay is still the safest option.

How can surgery cancellation be handled sensitively?

Canceling or postponing any surgery at the last minute is incredibly frustrating for patients. To help ease disappointment:

  • The surgeon should explain the situation and medical reasons for delay thoroughly.
  • Emphasize that this decision aims to optimize the patient’s safety and outcome.
  • Offer sympathy regarding the inconvenience and emotional letdown.
  • Apologize for any hardships caused by postponing procedures.
  • Describe clear plans for continued sinusitis management and recovery.
  • Schedule definite timeframes for reattempting surgery once sinus problems resolve.
  • Maintain kindness, optimism and reassurance regarding eventual surgical success.

When handled compassionately, patients tend to understand that postponing their procedure for sinusitis is in their best interest, despite the frustration it causes.


Sinusitis is a common reason surgeons may postpone scheduled operations, especially involving general anesthesia. Inflamed and infected sinuses can complicate anesthesia administration and increase post-operative respiratory risks. Treating underlying sinus inflammation and infection first allows safe surgery in the future.

With prompt medical therapy, minor cases of sinusitis typically resolve within a couple of weeks. More severe or chronic cases may warrant longer delays before surgery can safely proceed. Open communication from the surgical team regarding the need for and duration of delays helps the patient cope with this difficult situation.
