Botox for bulging temporalis muscle or excision of muscle?

Botox can be injected directly into the muscle and with time will cause muscle thinning. If this is truly the cause of your forehead widening then Botox injected a couple time a year should yield a good result. I would not recommend muscle excision in this area. It will be no better than Botox with much higher risk of complication

Hi and thank you for your question! In theory Botox can reduce the bulk of any muscles it is injected into and the same goes for using Botox to reduce bulkiness of temporalis muscle. However, I also suggest that you do a full-face evaluation with an experienced cosmetic doctor. Sometime the problem with an area might appear to be related to bulging muscle, while the root cause is volume loss in adjacent areas that contributed to that effect. Regardless, I don't recommend any surgical procedure for this. I hope it helps and good luck! 

Yes, Botox in combination with radiofrequency treatments can help improve this. Botox results last 3-4 months. I recommend getting a formal evaluation with a facial sculpting expert. Best, Dr. Emer
