What Are the Side-effects from Injecting Botox at the Site of the Depressor Septi Muscles?

when the muscle is treated with botox to prevent the tip of the nose from dropping, this could elongate the upper lip, failing to reveal as much of the upper teeth when smiling and making it difficult to say a few letters and difficult to get the toothbrush under the upper lip to clean the front incisors. This is temporary and only a couple of units of Botox should be used initially.

A flat upper lip, a droopy upper lip, asymmetric smile, just to name the most common ones. You should be very aware of the risk/benefit ratios. From MIAMI Dr. B

Botox injections into the depressor septal nasi muscle can be an effective, albeit temporary way to keep the tip from pulling downward when a person smiles. Side effects are minimal, however, too much botox or botox injected into the wrong location can result in a flattened upper lip but this is also temporary. There should be no problems with internal orthodontic work being done at the same time. I hope this information helps.
