Botox Use After Deep Plane Face Lift
Wait 2-4 weeks after deep plane face lift surgery before administering Botox to allow proper assessment of facial nerve function and avoid compounding asymmetries from both surgical edema and neurotoxin effects. 1
Optimal Timing for Post-Facelift Botox
The critical window is 2-4 weeks post-surgery, as this allows surgical edema to resolve sufficiently for accurate anatomical assessment while still being early enough to address emerging asymmetries. 1
Avoid injecting within the first 2 weeks: Two patients treated before 2 weeks developed reversed asymmetry because they recovered from transient neuropraxis while the Botox was still active, creating a new imbalance on the opposite side. 1
Waiting beyond 4 weeks is acceptable but may prolong the period of visible asymmetry if facial nerve injury has occurred. 1
Pre-Injection Assessment Requirements
Facial edema must be resolved before injection, as the American Academy of Dermatology emphasizes that existing edema obscures anatomical landmarks needed for precise injection and increases the risk of complications like ptosis. 2, 3
Key assessment steps include:
Evaluate for facial nerve injury patterns: Determine whether asymmetry involves the upper third (frontalis, orbicularis oculi) or lower face (smile deviation, marionette lines). 1
Analyze smile deviation vectors to identify which specific muscles on the non-paralyzed side require treatment to achieve symmetry. 1
Document baseline facial anatomy carefully, as altered surgical anatomy from the deep plane dissection changes normal landmarks. 4
Injection Protocol for Post-Facelift Asymmetry
Inject the non-paralyzed side to create temporary symmetry while awaiting potential nerve recovery. 1, 5
Dosing Guidelines
Use 1-2 volume-units per injection point on the functioning side to balance the paralyzed side. 1
Start conservatively: Patients with more severe rhytids requiring higher doses and those with altered surgical anatomy face increased complication risk. 4
Schedule re-evaluation at 15 days for outcome assessment and touch-up injections if needed. 1
Anatomical Considerations
The American Academy of Dermatology mandates aspiration before each injection to avoid intravascular administration. 3
Use appropriate anesthetic techniques for patient comfort, with lidocaine being safe even in special populations. 3
Precise anatomical placement is critical given the altered tissue planes from deep plane dissection. 2, 3
Duration and Re-Treatment Strategy
Distinguish between temporary neuropraxis and permanent nerve injury to determine long-term management:
Neuropraxis (temporary injury): Seven patients required only one Botox session, as nerve recovery and toxin effect resolved symmetrically over subsequent months. 1
Permanent nerve lesions: Six patients required re-treatment every 5-6 months indefinitely to maintain symmetry. 1
Upper face injuries (5 patients) were more likely to be permanent, with 4 of 5 requiring ongoing treatment. 1
Critical Safety Warnings
The FDA warns about distant spread of toxin effect, which can cause botulism-like symptoms including descending symmetric flaccid paralysis and respiratory compromise requiring mechanical ventilation in severe cases. 6, 7
Special precautions for post-surgical patients:
Patients with pre-existing neuromuscular disorders (myasthenia gravis, Lambert-Eaton syndrome, ALS) face exaggerated muscle weakness and systemic effects even at standard doses. 7
Anaphylaxis occurs in 1-2% of patients: Ensure epinephrine and antihistamines are immediately available during administration. 7
Dysphagia and breathing difficulties can occur, particularly relevant given the proximity to surgical sites affecting neck anatomy. 6
Common Pitfalls to Avoid
Injecting too early (before 2 weeks) risks creating reversed asymmetry if the patient recovers from temporary nerve injury while Botox is active. 1
Failing to account for altered anatomy from deep plane dissection increases the risk of complications, as surgical manipulation changes normal facial tissue relationships. 4
Using excessive doses initially: Complications are more common with higher doses, and effects are temporary but can last 3-6 months. 4, 1, 5
Not distinguishing temporary from permanent nerve injury leads to either over-treatment (if neuropraxis will resolve) or under-planning (if permanent injury requires indefinite management). 1
