How much Botox should be injected into depressor septi muscle?

Thank you for your question. Botox will not paralyze the muscle, it will only temporarily relax it. I would recommend seeing a board certified plastic surgeon or dermatologist for an assessment. 2-5 units may be able to help. Regards, 

Botox can be used to relax most facial muscles. 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 very minor. I would suggest you see a Rhinoplasty surgeon and have your nose examined thoroughly and go through some computer imaging to see what your nose might looks like after treatment.Good luck!

In general you can start with 2 units and see if it works. You can always add more but you can't take away and the risk of using too much in that area would be an absent or crooked smile. Once you know the dose that works for you it's easy to repeat. Hope that helps! 

Thank you for your question.  Though each person has a different sensitivity to Botox, the depressor is a small muscle and likely 2-5 units would be sufficient to help weaken the muscle's activity. Hope this helps.

Dear anonymous121212:As we age, the tip of the nose drops.  By relaxing the depressor septi muscle, you can counteract this effect to some extent. My patients have been happy with two units, although a slightly higher dose may last longer.All the best,Dr. Clark

First of all Botox does not really paralyze but weakens the muscle injected. to get the result you want it usually takes only 4 units of Botox in this area

Dear Anonymous121212,

Thank you for your clinical
post. The depressor septi muscle is a
muscle at the base of the partition of the nose called the columella and it
attaches these midline stretches of the nose to the nasal spine at the base. Contraction of the depressor septi muscle
pulls down the nasal tip. Over projected
noses with tension tips or tips that are under some degree of tension generally
have a significant degree of depressive septi nasi activity. Often these noses have very acute columellar
labial angle and surgically benefit from tip deprojection and myotomy of the
depressor septi nasi muscle. The use of
Botox in the depressor septi nasi muscle is also common. Generally, 5 units in the depressor septi
nasi muscle (as little as 3 units) can be used to deactivate this muscle and
minimize nasal tip plunging. The
addition of soft tissue fillers such as Juvederm into the nasal tip and the
columella can also provide tip support and minimize the risk of plunging.

Ultimately, cosmetic rhinoplasty
designed to enhance the nasofacial balance and proportion which would include
deprojection of the tip, slight rotation and removal of caudal septum and
weakening of the depressor septi nasi muscle may give you a long-term
improvement and relief from a tension tip that plunges on animation.

I hope this information is of some
assistance and best of luck.
