Correction of Recalcitrant Cicatricial Lower Lid Retraction and Entropion With Transverse Tarsotomy and Tarsoconjunctival Flap

Surgical Correction of Cicatricial Lower Eyelid Retraction: A Systematic Review

BACKGROUND

Cicatricial lower eyelid retraction is a challenging condition. It involves scarring of the lower eyelid, which causes it to retract and expose the sclera. This can lead to complications such as dry eye syndrome and corneal melting. It can be caused by trauma, burns, or previous eyelid surgery. Detailed assessment and understanding of eyelid anatomy and retraction are critical for successful surgical planning. Dynamic and static examinations of the eyelid including measurements of the lower eyelid margin reflex distance (MRD2) and scleral show are also essential to determine the appropriate treatment approach.

METHODS

A systematic review was conducted using Medline, Scopus, and Cochrane databases with keywords related to cicatricial lower eyelid retraction. The publication language was limited to English after 2000. A total of 29 articles were included for data extraction and analysis.

RESULTS

The main surgical techniques include tarsoconjunctival grafts, spacers, midface lift, and lateral canthal tendon suspension, although no single procedure has been universally recognized as the gold standard. New innovations such as synthetic grafts and xenografts are being explored for their potential in eyelid reconstruction. Severe cases, defined as those with inferior scleral show greater than 2 mm, may require a combination of reconstruction methods.

CONCLUSIONS

Correcting cicatricial lower eyelid retraction is a major challenge in oculoplastic reconstruction. The surgical approach should be individualized, considering the pathologies and etiologies of lid retraction. In-depth knowledge and careful surgical planning are essential for best outcomes. There is no gold standard technique, and postoperative outcomes, complications, and management vary depending on the surgical approach used.

Correction of Cicatricial Lower Eyelid Retraction and Entropion With Combined Scar Release, Hard Palate Graft, and Lateral Canthal Suspension

OBJECTIVE

This study aimed to evaluate the outcome of a technique-combined scar release, hard palate spacer graft with the recession of the lower eyelid retractors, lateral canthal suspension in the repair of cicatricial lower eyelid retraction, and entropion.

METHODS

Records of 12 patients with cicatricial lower eyelid retraction and entropion who underwent the surgery from January 2019 to August 2021 were reviewed. Surgical techniques include the following procedures: release of scar, hard palate graft with recession of the lower eyelid retractors, and lateral canthal tightening to strengthen the support of the lower eyelid. The follow-up period was at least 12 months. Postoperative outcomes were evaluated by the improvement of lower eyelid retraction, resolution of eyelid entropion, and complications.

RESULTS

All patients showed resolution in lower lid entropion, and lower eyelid retraction was significantly improved with a mean elevation of 2.93±0.82 mm. None of the patients had severe complications postoperatively, and both ocular surface symptoms and cosmetic appearance were significantly improved.

CONCLUSIONS

The technique achieves long-term stable outcomes in cicatricial lower lid retraction and entropion repair with a low morbidity rate.

Buccal mucosal membrane graft for correction of cicatricial lower eyelid retraction

BACKGROUND

To evaluate the outcomes of a surgical technique using buccal mucosal membrane graft for correction of cicatricial lower eyelid retraction.

METHODS

Twelve patients with unilateral cicatricial lower eyelid retraction were enrolled in the study. All patients underwent a four-step surgical technique consisted of release of scars, midface lift, transfer of buccal mucosal membrane to posterior lamella as spacer graft, and canthal tightening. All patients were followed for at least 12 months.

RESULTS

Mean preoperative Margin-to-Reflex-Distance 2 (MRD2) was 7.73 ± 1.10 mm, compared to mean postoperative MRD2 of 5.04 ± 0.49 mm (P < 0.0001). The mean improvement in retraction was 2.69 mm. Postoperative scleral show was present in only one case and no major complications were observed.

CONCLUSION

The four-step procedure (scar release, midface lift, buccal mucosal graft and canthal tightening) was an effective procedure to correct cicatricial lower eyelid retractions with acceptable outcomes and a low morbidity rate.

Hughes flap in the management of lower lid retraction

PURPOSE

We present a retrospective case series on the use of Hughes flap in managing acquired cicatricial lower lid retraction.

METHODS

This was a multicentre, retrospective case series. Data was collected from medical records across different sites within Australia (Adelaide, Melbourne, and Sydney) and New Zealand (Hamilton).

RESULTS

Fourteen patients were identified. The aetiology of cicatricial lower lid retraction included previous lid lesion excision and reconstruction, eyelid trauma, orbital fracture repair, orbital radiotherapy, and lateral canthal dystopia from previous lid surgeries. 4/14 (29%) cases had undergone other surgery to correct the retraction prior to the Hughes flap. Pre-operative lagophthalmos due to lower lid retraction was noted in 11/14 (79%) cases with a median 2 mm (range: 1-5 mm). Exposure keratopathy was present in 7/14 (50%) cases. There were no peri-operative complications during Hughes flap reconstruction. One patient had post-operative upper eyelid retraction that did not require any further intervention. One patient had persistent lagophthalmos and exposure keratopathy that is being managed conservatively. One patient had wound dehiscence and further lid retraction following flap division, which required further surgery. Median length of follow-up was 15 months (range: 0.5-84 months). At final review, improvement or resolution of symptoms was seen in 13/14 (93%) cases.

CONCLUSIONS

A Hughes flap is an effective surgical technique for the management of cicatricial lower lid retraction.

A Modified Hughes Flap for Correction of Refractory Cicatricial Lower Lid Retraction With Concomitant Ectropion

INTRODUCTION

Correction of lower eyelid retraction commonly involves one or more techniques, including recession of the eyelid retractors, spacer grafts, horizontal lid tightening, and midface lifting. However, patients presenting with cicatricial lower lid retraction following prior eyelid surgery often have scarring and concomitant ectropion or entropion that cause unpredictable wound healing, recicatrization, and suboptimal outcomes. The modified Hughes tarsoconjunctival flap is typically used to repair full-thickness eyelid defects. Prior reports describe treating refractory lower lid retraction with a modified Hughes flap placed beneath the tarsus after full-thickness blepharotomy. We present our experience with a novel surgical technique for treating refractory cicatricial lower lid retraction using a modified Hughes flap above the tarsus after excision of the scarred lid margin.

METHODS

Three patients were treated using this technique. The upper edge of the lower eyelid and associated scar tissue are excised. A modified Hughes flap is mobilized and secured above the posterior lamellar remnant. A full-thickness skin graft is placed over the flap. The flap is divided 4-5 weeks later.

RESULTS

This surgical technique was employed in all 3 cases. All cases were revisional, with 2 having extensive multioperative histories with multiple unsuccessful reconstructions and lid retraction repairs. All patients had improvement in cicatricial eyelid retraction, lagophthalmos, exposure keratopathy, and resolution of concomitant cicatricial ectropion.

CONCLUSIONS

The technique of using a modified Hughes flap to reconstruct above the tarsus with excision of the scarred lid margin was effective in correcting refractory cicatricial lower lid retraction. This procedure can be considered in multioperative cases in which traditional techniques for lower lid retraction repair have failed. Reconstructing a new lid margin reduces the risk of recicatrization and suboptimal results.
