What is Sphenopalatine Ganglion Block for Chronic Rhinitis?
The sphenopalatine ganglion (SPG, pterygopalatine ganglion) is a parasympathetic ganglion located in the pterygopalatine fossa, providing autonomic innervation to the nasal mucosa, lacrimal gland, and palatine glands. Activation of the SPG mediates rhinorrhea, congestion, lacrimation, and many features of chronic rhinitis and cluster headache. Targeting the SPG with local anesthetics, neurolytic agents, radiofrequency ablation, or peripheral neurostimulation provides therapeutic benefit.
SPG block is approached via transnasal topical application (cotton-tipped applicator soaked with lidocaine or bupivacaine, applied to the posterior superior nasopharynx through devices such as Sphenocath, Tx360, Allevio), transoral via greater palatine canal, or infrazygomatic with image guidance. Topical transnasal application is the simplest and safest, while infrazygomatic radiofrequency or pulsed radiofrequency provides more durable effect.
Indications include chronic refractory rhinitis (especially vasomotor or non-allergic), cluster headache (acute and prophylactic), migraine, trigeminal autonomic cephalalgias, post-dural puncture headache, post-traumatic headache, atypical facial pain, and trigeminal neuralgia (selected cases). Effects on rhinitis include reduction of rhinorrhea and congestion. Repeated treatments may be needed; SPG neurostimulation devices (Pulsante by Autonomic Technologies, no longer marketed in some regions) provided long-term option for cluster headache.

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.
