Levator Labii Superioris Alaeque Nasi Targeted Botulinum Toxin Injection for Treatment of Perinasal Facial Discomfort...

Botulinum toxin has been increasingly studied and used for varying conditions, most notably, cosmetics. However, it has been shown that botulinum toxin demonstrates a high efficacy in treating spasticity disorders throughout the body, including the face. Facial spasms vary in pathophysiology, region, and severity. Some can be so severe that they can cause discomfort and emotional distress due to the involuntary facial expressions caused by the spasms. Most spasticity conditions are often treated with adjuvant therapy of oral muscle relaxants and analgesics depending on severity. However, these treatments impose risks of varying adverse effects from sedation, hypotension, and if chronic use, more severe effects such as central nervous system complications or QT prolongation. In addition, if spasms are localized, the muscle relaxant's mechanism is not targeted, leading to unnecessary systemic use. That being said, a more targeted and manageable treatment such as botulinum toxin presents itself as a potential option for patient's physical condition and everyday life quality. Our case presents a 62-year-old male, with a chronic history of localized, idiopathic spasms and discomfort within the Levator Labii Superioris Aqulae Nasi region. The patient had no history of previous neurological disorders, and imaging was unremarkable. The patient had been treated over the past 13 years with varying oral therapeutics including Cymbalta, Ibuprofen, and cyclobenzaprine with limited improvement, but presented to the clinic seeking a different treatment plan, as the adverse effects from the muscle relaxants were impeding his everyday activities. The patient was also experiencing significant pain and emotional stress due to the spasms. The risk and benefits of treatment options were discussed and the patient decided to move forward with botulinum injections. After the first injection, the patient reported his pain had significantly improved and was relieved to be off of chronic pain medications. Our case demonstrates, what increasing literature further also supports: botulinum toxin is becoming a potential effective treatment for a breadth of spasticity disorders with a more targeted mechanism, and more manageable treatment plan, while simultaneously improving the patient's quality of life.
