I’m a 22 year old man and don’t want to overdo this stack. Currently 2mg reta weekly and .2mg CJC/IPA mix.

Does this seem excessive or redundant?

I’m looking for informed perspectives on post-op lip competence after bimax/MMA, specifically the ability for the lips to rest naturally without strain after advancement/rotation.

I understand this depends on multiple variables: magnitude/vector of maxillary and mandibular advancement, occlusal plane change, autorotation/counterclockwise rotation, soft-tissue envelope, incisor inclination, mentolabial fold dynamics, nasal base support, chin position, and pre-op lip posture.

My main questions:
What are the biggest predictors of post-op lip incompetence or strained lip seal?

How do surgeons plan around soft-tissue adaptation when significant advancement is needed?

Are there specific movements or combinations — large maxillary advancement, excessive incisor show changes, genioplasty, CCW rotation, etc. — that increase risk?

What pre-op measurements or ceph/CBCT findings are most useful for estimating this risk?
What mitigation strategies are commonly used intraoperatively or in planning?

I’m especially interested in perspectives from surgeons, orthodontists, OMFS residents, or patients who discussed this issue in detail with their surgical team.

Not asking for individualized medical advice, just trying to better understand the technical risk profile and planning logic around lip competence.
