What are the clinical effects of irritation of pterygopalatine ganglion?

The pterygopalatine ganglion is theorized to be a component for a group of headache disorders classified as trigeminal autonomic cephalalgias (TACs) which present as unilateral headaches with ipsilateral autonomic features (lacrimation, rhinorrhea, nasal congestion, eyelid edema, and ptosis).

What nerve supplies pterygopalatine ganglion?

greater petrosal nerve
The pterygopalatine ganglion (aka Meckel’s ganglion, nasal ganglion, or sphenopalatine ganglion) is a parasympathetic ganglion found in the pterygopalatine fossa. It is largely innervated by the greater petrosal nerve (a branch of the facial nerve); and its axons project to the lacrimal glands and nasal mucosa.

Is sphenopalatine ganglion and pterygopalatine ganglion same?

The pterygopalatine ganglion (also known as the sphenopalatine ganglion or, more rarely, the nasal ganglion or Meckel’s ganglion; Larsell and Fenton, 1928; Gloster, 1961) lies deep within the pterygoid fossa, rostral to the anterior opening of the pterygoid canal and inferior to the maxillary nerve (Kuntz, 1945; …

How many pterygopalatine ganglion are there?

four

What is the function of the Pterygopalatine ganglion?

The pterygopalatine ganglion is a parasympathetic nerve ganglion and one of four paired parasympathetic ganglia in your head. It sends out connections to the tear glands and mucous membranes of your mouth, throat, and nasal passages.

What is the function of the pterygopalatine ganglion?

How long does a sphenopalatine ganglion block last?

What are the branches of the Pterygopalatine ganglion?

Branches

• nasopalatine nerve.
• posterior superior nasal nerves.
• greater palatine nerve.
• lesser palatine nerves.
• pharyngeal nerve.

Where is the pterygopalatine ganglion located in the face?

The pterygopalatine ganglion (Meckel’s ganglion, nasal ganglion or sphenopalatine ganglion) is a parasympathetic ganglion found in the pterygopalatine fossa. It is largely innervated by the greater petrosal nerve (a branch of the facial nerve); and its axons project to the lacrimal glands and nasal mucosa.

How is the cervical ganglion connected to the sphenopalatine ganglion?

The cervical ganglion has a connection with the sphenopalatine ganglion via the deep petrosal nerve and the sphenopalatine ganglion is connected with the trigeminal nerve through the maxillary nerve.

Where does the palatine nerve send secretomotor fibers?

The palatine nerves send secretomotor fibers to the nasal glands and to the pharyngeal glands and all are branches of the maxillary nerve. Figure 2.The pterygopalatine ganglion and its branches. (Pterygopalatine ganglion visible but not labeled, as large yellow ganglion in upper-right center.) (From Gray’s Anatomy as presented on Wikipedia.1)

How is sphenopalatine ganglion neuralgia diagnosed and treated?

Sphenopalatine Ganglion Neuralgia Diagnosis and Treatment. The autonomic features often found to often be a part of the pain complex associated with the sphenopalatine ganglion tend to confound the clinician attempting to diagnose the reason for the patient’s headache that is typically described as a dull ache.
