Summary

Sudden deafness is a sudden, unexplained sensorineural hearing loss of ≥20 dBHL in at least two adjacent frequencies within 72 h. It may be accompanied by tinnitus, a sense of ear congestion, vertigo and other Symptoms.Stellate ganglion block increases the blood flow and blood velocity in the inner ear, keeping the body's vegetative, endocrine and immune functions normal.The branches of the facial and linguopharyngeal nerves are connected to the inner ear, and local injection can nourish the nerves and improve local circulation.

Conditions

• Sudden Deafness

Interventions

Type	Name	Description
PROCEDURE	Stellate ganglion block	A cross-sectional scan with a high-frequency line array probe reveals the pre-C6 transverse nodule or C7 transverse process, and the structures of the thyroid, carotid sheath, vertebral artery, inferior thyroid artery, trachea, and esophagus are identified by observation. The carotid sheath is pushed out as far as possible laterally, the needle is inserted in the paratracheal sulcus, and the tip of the needle is passed through the lateral border of the thyroid into the deep anterior fascial surface of the long cervical muscle.After backdrawing no blood, cerebrospinal fluid or gas, 5 ml of lidocaine was injected.（lidocaine 80mg；Physiological saline 1ml）
PROCEDURE	Facial and glossopharyngeal nerve blocks	The operator touches the position of the mastoid process and needles vertically at the front of the mastoid process directly below the external auditory canal. When the surface of the mastoid is touched, the needle is adjusted to pass through the front of the mastoid and then slowly needled for about 1 cm, and when the patient develops swelling and pain, 3 ml of the drug is injected. then the needle is slowly needled backward for about 1 cm, and when the patient develops swelling and pain, 2 ml of the drug is injected. （mecobalamin injection 1mg；lidocaine 20mg； dexamethasone 10mg ；Physiological saline 2ml）
DRUG	Mecobalamin Tablets	oral Mecobalamin Tablets tid-8
