A 70-year-old woman with heavy upper lids is scheduled for blepharoplasty elsewhere, but on examination her eyebrows sit low — nearly at the orbital rim — pushing skin downward. She habitually raises her brows to see, with deep forehead furrows.
Examination Findings
Bilateral brow ptosis with brows at or below the supraorbital rim, compounding moderate dermatochalasis. Manually elevating the brows (not just the lid skin) restores the field and a natural contour. Frontalis overaction is evident. Lid margins and levator function are normal.
Investigations
Brow position assessment (brow-to-rim distance) quantifies the ptosis. The manual brow-elevation test demonstrates how much of the “lid heaviness” is brow-driven. Visual-field testing with brow supported documents the functional component. Photographs in repose and with brow elevation plan the combined approach.
Questions to Think About
- How do you tell brow ptosis from lid ptosis or dermatochalasis at the bedside?
- Why does blepharoplasty alone fail when brow ptosis is missed?
- What are the surgical options for the brow component?
Diagnosis
Bilateral brow ptosis contributing to upper-lid heaviness, with dermatochalasis.
Reasoning
Reasoning: Low brows pushing skin onto the lids, with frontalis overaction and field restoration on brow elevation, is brow ptosis contributing to the heavy-lid complaint — blepharoplasty alone would remove skin while the brow keeps pushing more down. Diagnosis: brow ptosis with dermatochalasis. Management: typical management addresses both levels: brow lifting (direct, temporal or endoscopic brow lift per surgeon preference and patient factors) combined with conservative blepharoplasty as needed. She is counselled that the brow is half the diagnosis, that forehead numbness or asymmetry are discussed risks, and that the combined plan gives a natural result where lid-only surgery would disappoint.
Differential Diagnosis
- Brow ptosis with dermatochalasis — favoured: low brows, frontalis overaction, field restored by brow elevation.
- Isolated dermatochalasis — incomplete: lid skin alone does not explain the low brows and forehead furrows.
- True eyelid ptosis — ruled out: lid margins and levator function are normal.
Management
Typical management includes brow-lift surgery (technique matched to anatomy, hairline and patient preference) with conservative upper blepharoplasty if residual skin redundancy remains. Pre-operative counselling covers brow-surgery risks (numbness, asymmetry, hairline changes) and the rationale for treating both levels. Follow-up assesses brow position, lid contour and patient satisfaction.
Key Learning Points
- BROW PTOSIS pushes skin down onto the lids — the brow-to-rim distance is the measurement.
- The manual brow-elevation test shows how much heaviness is brow-driven: if lifting the brow fixes it, the brow is the problem.
- Lid-only surgery fails missed brow ptosis — treat both levels for a natural result.
- Frontalis overaction with forehead furrows is the bedside clue.
Red Flags
- Blepharoplasty without assessing the brow — missed brow ptosis guarantees a poor result.
- Over-elevating the brow — surprised look; conservatism and symmetry matter.
- Frontalis-dependent vision — these patients “see through” brow lifting; document it pre-operatively.
