Botulinum toxin is not usually used for a nonsurgical rhinoplasty, but botulinum toxin does have its place when it comes to improving the nose. For example, it can be used to relax the depressor septi, a small muscle that pulls the tip of the nose down and widens the nostrils.
The depressor septi muscle is a common factor in droopy nasal tips. This muscle connects the central base of the nose and upper lip. The depressor septi muscle is a centrally located muscle that is typically not too thick or wide. Patients with a very strong depressor septi muscle often also have a very droopy nasal tip. These patients may also have a relatively short upper lip or a gummy smile too. Smiling or facial animation activates this muscle (among several facial muscles) which can pull on the nasal tip downward.pper lip. Botulinum toxin can be placed in the depressor septi nasii to prevent the tip of the nose from moving downward (lessen the droop) when smiling or talking. In general, one can start with 2 units and see if it works. The common side effects if too much is administered or it is administered incorrectly/migrating of the product include flattening/droopiness of the upper lip, due to paralysis of those muscles, and may affect the normal ability to drink, smile (asymmetric smile) and speak.
Although the depressor septi has some effect on the nose drooping with smiling it is only part of the cause. You may see some improvement but it would be rather minor. This method of non-surgical rhinoplasty is a quick office procedure and lasts about 3 months. Results without surgery tend to be more subtle as compared to surgical rhinoplasty. Botox injections can be an initial step, then I would suggest an appointment with a plastic surgeon to discuss rhinoplasty and have your nose examined thoroughly, if a more dramatic and and permanent change is desired.
