"The most important question in acute sinusitis is when antibiotics are actually needed — and when they are not."
A Note from Dr. Mourad
"Acute sinusitis is inflammation of the sinuses lasting less than four weeks — most commonly viral, occasionally bacterial. The right management depends on duration, severity, and the trajectory of symptoms."
— Dr. Moustafa Mourad, MD
Overview
What is acute sinusitis?
Acute sinusitis is an inflammation of the lining of one or more of the paranasal sinuses that lasts less than four weeks. Most cases begin as a viral upper-respiratory infection; a smaller proportion progress to a bacterial infection when sinus drainage is blocked and secretions become trapped behind a swollen sinus opening.
It produces facial pressure or pain, nasal obstruction, thick discolored nasal discharge, post-nasal drip, reduced sense of smell, and sometimes fever or dental pain. Symptoms are concentrated over the affected sinuses — the cheeks, between or behind the eyes, or the forehead.
Most episodes resolve with supportive care: saline irrigation, decongestants, nasal steroid sprays, and time. Antibiotics are reserved for cases that meet specific bacterial criteria. Recurrent or prolonged episodes warrant evaluation for an underlying anatomic or inflammatory driver.

02 · Symptoms
How this condition typically presents.
Three patterns are most common. Patients often recognise themselves in one or more of these.
I
Facial Pressure & Pain
Localised pressure or pain over the affected sinus — most commonly the cheek, forehead, or between the eyes.
II
Nasal Obstruction & Discharge
Thick nasal discharge, congestion, and reduced sense of smell, often with post-nasal drip.
III
Systemic Symptoms
Fever, fatigue, and worsening symptoms after initial improvement — a pattern that may suggest bacterial infection.
03 · Anatomy
Viral vs bacterial sinusitis.
The distinction matters because the treatment is different. Most acute sinusitis is viral and self-limited; a smaller proportion is bacterial and benefits from antibiotics.
Viral
The common pattern
Viral sinusitis is the most common form — symptoms peak in the first 3 to 5 days and steadily improve thereafter. Antibiotics are not indicated.
Supportive care — saline irrigation, hydration, rest, and selective use of decongestants — is the right management for the typical case.
Bacterial
When antibiotics are appropriate
Bacterial sinusitis typically presents with one of three patterns: symptoms persisting beyond 10 days without improvement, severe symptoms with fever and purulent discharge, or initial improvement followed by worsening.
When the clinical pattern fits, a targeted antibiotic course is appropriate; broad-spectrum coverage is reserved for specific situations.

04 · Diagnosis
How the diagnosis is made.
Diagnosis is clinical for most cases — symptom duration, character, and trajectory are the key variables.
Nasal endoscopy is performed when symptoms are atypical, prolonged, or recurrent.
Imaging is reserved for suspected complications or cases that have not responded to appropriate therapy.
05 · Treatment Options
Treatments matched to the diagnosis.
Treatment is individual. The right answer ranges from optimised medical therapy to a focused procedure to definitive surgery.
Medical Therapy
Saline irrigation, topical decongestants, intranasal steroids, and selective use of antibiotics.

01 · Why Dr. Mourad
Diagnosis first, treatment second.
Dr. Mourad approaches acute sinusitis with a clear diagnostic framework — viral versus bacterial, uncomplicated versus complicated — to avoid the over-prescription of antibiotics.
In-office evaluation including nasal endoscopy clarifies the cause; imaging is reserved for cases that warrant it.
When antibiotics are appropriate, they are prescribed deliberately; when they are not, the conversation about supportive care is just as deliberate.
When to Seek Care
When to seek care promptly.
Severe facial pain, high fever, or visual changes — these warrant urgent evaluation.
Significant facial swelling or redness around the eye — evaluate immediately.
Severe headache, neck stiffness, or change in mental status — evaluate immediately.
Symptoms not responding to appropriate therapy within 5 to 7 days — return for re-evaluation.
Outlook
What to expect.
When the diagnosis is correct and the right treatment is applied, the outlook is generally good. Most patients describe meaningful improvement in symptoms and day-to-day function.
When symptoms persist despite treatment, the workup is re-opened. Persistent symptoms with no answer almost always mean the diagnosis is incomplete.
Living Well
Day-to-day measures that help.
Daily saline irrigation, control of indoor allergens, and good sleep hygiene meaningfully reduce day-to-day symptoms for many patients.
Medical therapy, when prescribed, works best when used consistently rather than as needed — this is one of the most common reasons treatment seems to fail.
Frequently Asked
Patient questions, honestly answered.
Acute sinusitis is symptomatic inflammation of the paranasal sinuses that typically lasts up to four weeks. Most episodes begin after a viral upper respiratory infection and improve within 7–10 days. Symptoms that persist beyond 10 days or follow a pattern of initial improvement and then worsening suggest possible bacterial infection. Final diagnosis and management require clinical assessment and, when helpful, office nasal endoscopy.
The Most Important Step
Get an expert evaluation.
A careful evaluation by a double board-certified physician is the right first step. The conversation is unhurried, the diagnosis is honest, and treatment is matched to what you actually have.
