In 1967, Professor Jennatta pioneered microvascular decompression for the treatment of facial muscle spasm. The procedure was performed by drilling a 1.5 to 2.0 cm diameter bone hole behind the affected ear.
The facial nerve root was exposed under the microscope, and the blood vessel compressing the facial nerve root was found and then freed, and the compressed blood vessel was removed from the nerve with Teflon cotton.
Teflon cotton was used to pad the compressed blood vessel away from the nerve, eliminating the cause of the facial spasm, which would stop immediately or gradually. Since the 1980s, this surgical method has become the preferred treatment for facial spasm in the international arena.
To date, more than 50,000 patients worldwide have undergone surgery for facial spasm. The overall cure rate worldwide is between 82% and 99%, and the recurrence rate is only about 1-5%.
The recurrence rate is only about 1-5%. In China, Professor Zuo Huanzheng’s team (now Tsinghua University Yuquan Hospital, formerly China-Japan Friendship Hospital) first performed this surgery in 1984, and after more than 20 years of development and improvement, the cure rate has reached 98%, and the complication rate is 1-2%. Prognosis The disease is curable, and surgery is the only means of cure. Although there are risks of general anesthesia and neurosurgery, the treatment is effective and safe, and the prognosis is good.
