Vocal cord injection therapy has many advantages. (Photo courtesy of Taipei Rong General Hospital) Dr. Xu Yanbin from the Department of Otolaryngology and Neck Department of Taipei Rong General Hospital said that after endoscopic examination of the vocal cords of the patients, cysts were found on the vocal cords, which led to abnormal sound. Finally, vocal cord injection was performed in outpatient department and followed up for two weeks after operation. Endoscopic examination also found that the vocal cord cyst had healed and disappeared, and the patient also said that his voice had completely recovered and he could continue his normal teaching.
Vocal cord injection is widely used in outpatient department.
The common causes of hoarseness are vocal nodules (long cocoons), polyps and cysts, which are mainly related to improper or excessive use of sound. If not treated immediately, it may have an impact on daily life and work. Some minor vocal cord diseases can be treated by changing pronunciation habits or using drugs. In many cases, surgical resection should be considered. Because the larynx is a very sensitive organ, traditionally, laryngeal or vocal cord surgery must be performed under general anesthesia, which not only bears the risk of general anesthesia, but also often requires hospitalization and is expensive.
Many faculty members have hoarse voices. Dr. Xu Yanbin said that vocal cord injection has been widely used to treat vocal nodules, polyps and cysts, or vocal cord paralysis and vocal cord atrophy, and most patients' symptoms have been significantly improved after treatment. Different drugs will be used to treat different vocal cord problems. For example, vocal nodules, polyps and cysts can be treated with steroids on the vocal cords.
As for the treatment or improvement of vocal cord paralysis or vocal cord atrophy, autologous fat and hyaluronic acid are used to increase the volume of vocal cords and help them close.
Vocal cord injection has many advantages and is very safe.
Vocal cord injection therapy has many advantages, including it can be carried out in outpatient department without hospitalization, and it can avoid the risk and cost of general anesthesia. Because the injection uses a 25-gauge fine needle, the damage to the vocal cords is very small, and there will be no scar and sclerosis of the vocal cords after laryngeal surgery. In addition, through neck injection, drugs can be accurately delivered to the lesion. After receiving one injection, about 90% patients have made remarkable progress.
Because of local injection, the dose is small, and there will be no systemic absorption or steroid side effects that most people are worried about. It can be said that it is very safe and a good treatment choice besides traditional endoscopic surgery.
