What is Sphenoid Sinusitis?

The sphenoid sinus lies deep in the skull base and shares walls with the optic nerve, cavernous sinus, internal carotid artery and pituitary gland, so its inflammation can mimic neurologic disease and may cause serious complications.

Causes include viral, bacterial or fungal infection, mucocele, anatomic obstruction or extension from neighbouring sinuses. Diagnosis often requires CT or MRI as physical exam and rhinoscopy may be normal.

Isolated sphenoid sinusitis is uncommon (around 3% of all sinusitis) but its recognition is critical because untreated disease can progress to cavernous sinus thrombosis, meningitis or visual loss.

Symptoms

Deep vertex or retro-orbital headache

Occipital pain

Photophobia

Visual disturbance

Cranial nerve palsy

Postnasal drip

Fever in acute infection

Risk Factors

Allergic rhinitis

Anatomic obstruction of the sphenoid ostium

Immunosuppression

Diabetes mellitus

Recent upper respiratory infection

Nasal polyps

Skull base trauma or surgery

When to See a Doctor?

If you experience any of the following symptoms, seek medical attention promptly:

Severe headache unresponsive to analgesics
Visual disturbance or diplopia
Cranial nerve deficit
Persistent fever
Meningitis suspicion
Worsening symptoms despite antibiotics

Treatment Methods

Targeted antibiotic therapy (extended course often needed)

Decongestants and saline irrigation

Topical or systemic corticosteroids

Endoscopic sphenoidotomy in refractory cases

Cranial imaging if complications suspected

Antifungal therapy when fungal etiology

Anaemia

Dahiliye (İç Hastalıkları)

Anaemia is a low haemoglobin level that reduces oxygen delivery, causing fatigue, pallor, and shortness of breath. It is not a disease itself but a sign of many underlying conditions. Most cases are correctable with appropriate diagnosis and treatment.

Iron Deficiency Anaemia

Dahiliye (İç Hastalıkları)

Iron deficiency anaemia develops when dietary intake, absorption, or losses create an iron shortfall, most often affecting women and children. Identifying the underlying cause is the core of management, alongside iron replacement.

Vitamin B12 Deficiency

Dahiliye (İç Hastalıkları)

Vitamin B12 deficiency can cause megaloblastic anaemia, neurological symptoms, and cognitive impairment. Early treatment with intramuscular or oral B12 largely prevents irreversible complications.

Hypertension (High Blood Pressure) Management

Dahiliye (İç Hastalıkları)

Hypertension is often called the silent killer because it progresses symptom-free for years and can damage the heart, brain, kidneys, and eyes. Regular monitoring, lifestyle change, and evidence-based drug therapy dramatically reduce cardiovascular risk.

Chronic Kidney Disease

Dahiliye (İç Hastalıkları)

Chronic kidney disease is one of the most common complications of chronic conditions such as diabetes and hypertension, and can be silent in its early stages.

Hepatitis B (HBV)

Dahiliye (İç Hastalıkları)

Hepatitis B is a DNA virus infection causing acute and chronic hepatitis with risk of cirrhosis and hepatocellular carcinoma; diagnosis integrates HBsAg, HBeAg, anti-HBc, and HBV DNA with management based on disease phase using nucleos(t)ide analogues (entecavir, tenofovir) and universal infant vaccination.

Hepatitis C (HCV)

Dahiliye (İç Hastalıkları)

Hepatitis C is an RNA virus causing chronic hepatitis that may progress to cirrhosis and hepatocellular carcinoma; modern direct-acting antiviral (DAA) pangenotypic regimens (sofosbuvir/velpatasvir, glecaprevir/pibrentasvir) achieve sustained virologic response over 95% in 8–12 weeks with universal adult screening and cure for nearly all patients.

Fatty Liver Disease

Dahiliye (İç Hastalıkları)

Non-alcoholic fatty liver disease (NAFLD) is closely related to obesity and metabolic syndrome and is largely reversible with early treatment.
