Facial Pain and Sinus Headaches: Is It Really Your Sinuses?

Written by Mr Tim Biggs | Consultant ENT Surgeon | Rhinology & Facial Plastics

The Problem With Blaming the Sinuses

Facial pain and headache are amongst the most frequently self-diagnosed sinus problems, and the sinuses are one of the most frequently blamed causes of headache in both primary care and patient self-assessment. The reality is considerably more nuanced. Research consistently shows that a significant proportion of patients who believe they have chronic sinus headache are in fact experiencing migraine or another primary headache disorder, and that the sinuses are entirely normal when properly investigated.

This matters because treating the wrong condition is ineffective and delays appropriate management. Sinus surgery performed for headache without objective evidence of sinus pathology is unlikely to provide benefit. Conversely, genuinely sinonasal pain that is misattributed to migraine and treated with triptans will not resolve either. A careful, methodical diagnostic approach is essential.

What Does True Sinonasal Pain Feel Like?

Pain arising from the sinuses themselves typically has particular characteristics. Acute sinusitis produces a dull, pressure-like pain over the affected sinus, most commonly the cheeks (maxillary) or forehead (frontal). It is associated with nasal congestion, mucopurulent discharge, and often fever.

Chronic sinusitis, however, more commonly causes pressure or fullness rather than frank pain, and the relationship between CT findings and symptom severity is often surprisingly weak. Patients with significantly abnormal sinuses on imaging may have mild symptoms, while patients with severe pain may have relatively minor mucosal changes.

Conditions That Mimic Sinus Pain

Migraine

Migraine is the most commonly misidentified mimic of sinus pain. Migraines frequently present with facial pain, nasal congestion, and clear nasal discharge, all of which patients and clinicians understandably attribute to the sinuses. The combination of unilateral facial pain with nasal autonomic features, including congestion, rhinorrhoea, and eye watering, is in fact characteristic of a subset of migraine and cluster headache. A detailed headache history, including frequency, duration, associated features, and response to triptans, is essential to identify this diagnosis.

Tension-Type Headache

Tension-type headache produces bilateral pressure or tightness across the forehead and temples that patients frequently describe as a sinus feeling. In the absence of nasal symptoms or sinus disease on imaging, a primary headache diagnosis should be considered and neurological assessment arranged.

Temporomandibular Joint Dysfunction

TMJ dysfunction can refer pain to the face, ear, temple, and even the teeth, and is a common cause of facial pain that is sometimes mistaken for a sinus problem. Jaw clicking, morning jaw stiffness, and pain triggered by chewing are important clues.

Dental Pathology

The roots of the upper back teeth lie immediately below the floor of the maxillary sinus. Periapical dental abscess, cracked tooth syndrome, and other dental conditions can produce pain indistinguishable from maxillary sinusitis. A dental assessment is appropriate when facial pain is localised to the upper jaw, particularly when CT imaging shows isolated maxillary disease.

Investigation

For patients presenting with facial pain or headache in whom a sinonasal cause is being considered, nasal endoscopy is the first step. A normal endoscopy makes significant sinus pathology unlikely but does not exclude it entirely. CT scanning of the paranasal sinuses provides definitive anatomical information and is obtained where endoscopy is equivocal or where surgery is being considered. Normal CT imaging in the context of recurrent facial pain strongly directs attention toward a primary headache diagnosis.

Management of facial pain

Management is entirely determined by the underlying diagnosis. True sinonasal pain from acute or chronic sinusitis responds to appropriate medical treatment, with FESS reserved for those who fail adequate conservative management. Contact point headache, once confirmed, may be addressed surgically with good results. Migraine and other primary headache disorders are managed medically in collaboration with neurology where appropriate. TMJ dysfunction is referred to maxillofacial or dental colleagues.

I take a genuinely diagnostic approach to facial pain. I am as likely to tell a patient that their sinuses are not the cause of their pain as to recommend sinus surgery, and I consider that transparency an essential part of good rhinological practice.

Arrange a Consultation

If you have been told you have a sinus problem but treatments are not working, or if you have persistent facial pain or headache that has not been properly investigated, I would be glad to assess you.

I see patients privately. Contact my secretary Michele Hewlett to arrange a consultation. Fees are available at www.hampshireentclinics.co.uk.

Frequently Asked Questions

Is facial pain always caused by the sinuses?

No. Most facial pain attributed to the sinuses is not of sinonasal origin. Migraine, tension-type headache, TMJ dysfunction, and trigeminal neuralgia all commonly present with facial pain and are frequently misattributed to the sinuses.

What is rhinogenic headache?

Rhinogenic headache is headache or facial pain arising directly from sinonasal pathology, including contact point headache (controversial), acute sinusitis pain, and referred pain from chronic sinus disease.

How is true sinus pain diagnosed?

True sinonasal pain is confirmed by nasal endoscopy and CT sinus imaging. Normal imaging in a patient with recurrent facial pain strongly suggests a non-sinonasal cause.

Can sinus surgery cure sinus headaches?

Where headache is genuinely caused by sinus disease, FESS can be highly effective. However, performing surgery without objective evidence of pathology is unlikely to help. A careful diagnostic workup is essential.
