Transconjunctival blepharoplasty

What it treats

• Tomlinson and Hovey described the transconjunctival approach in 1975 in 7 patients, calling it an excellent operation for patients with prominent lower lid fat who do not need skin resection (PMID 1153547).
• The approach suits bulging orbital fat without significant skin excess; fat can be resected, or preserved and draped over the rim, or used as a free graft, depending on presentation (PMID 33906758).
• Dodenhoff extended the indications to patients with fine wrinkles, excess skin and redundant orbicularis muscle by adding a chemical peel, a skin pinch or a canthoplasty to the fat step (PMID 8638486).
• Jacono and Moskowitz favor the transconjunctival approach for the lower lid because it circumvents the lower eyelid retraction risk associated with the transcutaneous skin-muscle flap (PMID 11518974).

How it is done

• Baylis reported 122 consecutive transconjunctival cases: no lid retraction or ectropion; the main problem was fat left behind, in 7.4% (PMID 2771349).
• Netscher compared the transconjunctival and transcutaneous approaches left-right in 10 patients; both were graded the same at 6 months (PMID 7568479).
• Fat handling options through the transconjunctival incision: excision alone, fat preserved and draped over the orbital rim as a pedicled flap, or fat excised and then free-grafted back (PMID 33906758).
• Refined orbital fat trimming, 97 patients: fat volume is deliberately trimmed rather than fully preserved, to correct fat herniation and tear trough while avoiding midfacial overfilling from fat-preserving technique (PMID 41137243).
• Fat handling technique that moves rather than removes the fat, including the orbital rim planes used and the tear trough results, is covered in fat-repositioning-lower-blepharoplasty.md.
• Skin pinch: a fold of loose lower lid skin is excised without undermining, added to the transconjunctival fat step; 71 patients, mean 8 mm removed (range 4-12 mm), temporary scleral show in 3 (PMID 18434828).
• Skin pinch did not change lid height: a 0.05 mm difference with or without the pinch, 45 patients (PMID 18209632).
• Chemical peel adjunct: transconjunctival fat removal combined with trichloroacetic acid and phenol chemoexfoliation in 146 patients, without an external scar (PMID 8826588).
• Laser adjunct: CO2 laser resurfacing added to transconjunctival blepharoplasty, either immediately or 2 months later, in a randomized trial of 44 subjects (PMID 11237896).
• Full-field Er:YAG laser resurfacing performed simultaneously with skin pinch lower blepharoplasty, 25 patients, alongside tear trough microfat grafting and blunt orbital retaining ligament release (PMID 42108678).
• Integrated technique, 248 patients over 4 years: fat excision in 91%, fat transposition in 61%, skin excision in 63%, trichloroacetic acid peel in 62%, temporary tarsorrhaphy in 31%, lateral canthopexy in 18% (PMID 21200234).
• American Society of Ophthalmic Plastic and Reconstructive Surgery member survey: transconjunctival approach used by 96% of respondents, transcutaneous by 82% (PMID 28151825).

Results and evidence

• Postseptal transconjunctival technique, 88 patients: swelling, bruising and chemosis were common and typically resolved within 1-2 weeks; 14 patients had a foreign body sensation resolving in 48-72 hours; average return to social activity was 2 weeks (PMID 39628738).
• Refined fat trimming series, 97 patients, mean follow-up 8.2 months: mean operative time 56.3 minutes; FACE-Q satisfaction with eyes score 3.63 of 4, with 67.0% "very satisfied" and 29.9% "somewhat satisfied" (PMID 41137243).
• Randomized trial of CO2 laser timing, 44 subjects: transconjunctival blepharoplasty alone improved lower lid bulging in 92% of subjects, while wrinkling worsened in 46%; adding laser resurfacing gave a statistically significant wrinkle improvement (P<0.0005) regardless of timing; no subject developed lower lid retraction (PMID 11237896).
• Comparative laser study, 36 patients (20 transconjunctival plus laser, 16 transcutaneous): bulging improved in 92% of the transconjunctival-plus-laser group against 98% of the transcutaneous group (PMID 17510867).
• Erbium laser plus skin pinch, 25 patients: mean Barton tear trough score improved from 2.88 to 0.52 (P<0.0001); mean MRD2 was unchanged, 3.75 mm against 3.71 mm (P=0.65), indicating lid position was preserved (PMID 42108678).
• Literature review, 49 studies, 10,698 patients, mean follow-up 14.8 months: pooled reoperation 0.77%, scleral show 0.37%, lid malposition 0.25%, ectropion 0.24% (PMID 30084870).

Risks and complications

• Transconjunctival blepharoplasty alone, 15 eyes (some with added Erbium laser, TCA peel or fat transposition): MRD2 decreased, meaning the lid elevated, in 73%; scleral show was eliminated in 86% of the eyes that had it; no lid retraction occurred (PMID 26537512).
• Same comparative laser study: the transcutaneous group had lateral canthal rounding in 3.2% and ectropion in 6.25%, against persistent erythema in 5% and hyperpigmentation in 10% in the transconjunctival-plus-laser group, which also had 80% of patients reporting long postoperative care (PMID 17510867).
• Cadaver study, 46 hemifaces: the pretarsal motor nerve safe zone for a lower lid muscle incision lies 6.0-6.5 mm below the lid margin, 9.4 mm from the medial canthus line and 3 mm from the lateral canthal crease (PMID 37384881).
• Randomized trial, CO2 laser against monopolar cautery, 78 patients: the laser group had less chemosis; conjunctival granuloma occurred in 7.89% of the cautery group (PMID 36723988).
• Persistent chemosis, 1,047 patients: type 3 chemosis was more frequent after transcutaneous surgery with lateral canthoplasty than after transconjunctival surgery, and more frequent with radiofrequency (PMID 38610858).
• Systematic review, 36 articles: no major complications with visual disturbance were reported for lower eyelid blepharoplasty (PMID 40995580).
• Review of 24 cohort studies, 2000-2025: both the transconjunctival and transcutaneous incisions are safe for fat-preserving technique; reporting is too weak to name a best approach (PMID 41415593).
• Retraction repair series without an internal spacer graft, 11 patients, 17 procedures, most with prior lower blepharoplasty: mean improvement in marginal reflex distance was 2.2 mm (range 1.6-2.8 mm), with one mild overcorrection (PMID 27590867).

Recovery

• Postseptal series, 88 patients: swelling, bruising and chemosis resolved within 1-2 weeks; average return to social activity 2 weeks (PMID 39628738).
• Refined fat trimming series, 97 patients: transient lower eyelid swelling in all patients resolved within 8 weeks; mild chemosis in 2.1% resolved within 2 weeks; mild bleeding of 0.5 mL or less in 7.2% (PMID 41137243).
• Combined skin pinch and Er:YAG resurfacing, 25 patients: transient chemosis in 6 patients and prolonged erythema in 2, all resolving with conservative care; no ectropion, retraction, new scleral show or vision-threatening complication (PMID 42108678).
• Laser resurfacing after transconjunctival blepharoplasty produced complaints of long postoperative care in 80% of one laser-treated group, against a shorter recovery reported for the transcutaneous group in the same comparison (PMID 17510867).

With a facelift

• Dodenhoff combined transconjunctival fat removal with a chemical peel, a skin pinch excision or a lateral canthoplasty at the same operation (PMID 8638486).
• Integrated technique series, 248 patients: lateral canthopexy was added in 18% and temporary tarsorrhaphy in 31% (PMID 21200234).
• Postseptal series, 88 patients: 19 had additional canthoplasty or canthopexy and 87 received fat transfer to correct a negative vector (PMID 39628738).
• Graded approach to the lower lid: isolated bags may be treated by transconjunctival fat resection alone; mild skin laxity adds a skin pinch; fine lines add a peel or laser; a lid-cheek junction abnormality adds orbicularis retaining ligament release and canthal tightening (PMID 28027251).
• Fat repositioning and tear trough correction, often combined with the transconjunctival incision, are covered in fat-repositioning-lower-blepharoplasty.md.

Current questions

• Fat removal against fat preservation through the transconjunctival incision: a 2025 review of 24 studies found reporting too weak to name a best approach (PMID 41415593).
• Preventing overfilling from fat-preserving technique: a 2025 series added deliberate fat trimming to a preservation-based transconjunctival technique specifically to avoid midfacial bulge (PMID 41137243).
• Choice of skin adjunct (pinch, peel or laser) is reported by surgeon preference; no trial identified compares the three head to head (PMID 33906758).
• Laser resurfacing after transconjunctival blepharoplasty trades a longer, more care-intensive recovery for a wrinkle improvement that fat surgery alone does not provide (PMID 17510867; PMID 11237896).
• Retraction risk after transconjunctival surgery is reported as near zero across current series, in contrast to the retraction risk historically attributed to the transcutaneous skin-muscle flap (PMID 26537512; PMID 11518974).

Terms

• Transconjunctival approach: incision on the inner surface of the lower lid; no external scar (PMID 1153547).
• Postseptal plane: the surgical plane entered behind the orbital septum to reach fat directly (PMID 39628738).
• Skin pinch: excision of a fold of loose lower lid skin without undermining (PMID 18434828).
• Chemoexfoliation: a trichloroacetic acid or phenol chemical peel applied to lower lid skin (PMID 8826588).
• CO2/Er:YAG laser resurfacing: ablative laser treatment of lower lid skin for fine wrinkles (PMID 11237896).
• MRD2: margin reflex distance 2, from the corneal light reflex to the lower lid margin, used to measure lid position (PMID 26537512).
• Scleral show: white of the eye visible below the iris, a sign of lid retraction (PMID 26537512).
• Fat preservation: leaving orbital fat in place, or repositioning it, rather than excising it (PMID 33906758).
• Negative vector: a globe that projects forward of the cheek in profile, a risk factor for lid malposition addressed with fat transfer or canthal support (PMID 39628738).
