Mini-incisional entropion repair for correcting involutional entropion: Full description and surgical outcome

Transcanthal Canthopexy for Involutional Lower Eyelid Entropion Corrects Horizontal Laxity

In this prospective observational study, we aimed to examine improvements in horizontal laxity after lower eyelid retractor advancement and transcanthal canthopexy for involutional lower eyelid entropion. The study included 19 sides in 15 patients with involutional entropion who underwent transcanthal canthopexy with the advancement of the lower eyelid retractor. Using the pinch test, the distance from the lowest part of the corneal limbus to the eyelid margin was measured using callipers. All measurements were performed preoperatively and at postoperative 3 and 6 months. Using the pinch test, the distance from the lowest part of the corneal limbus to the lower eyelid margin was significantly shortened during each postoperative follow-up period. None of the included cases experienced recurrence. Our results indicated that transcanthal canthopexy could preserve postoperative horizontal tightness.

Outcomes of combined procedures compared to various single techniques for involutional entropion

BACKGROUND

To describe the outcomes of triangular tarsectomy and limited orbicularis myectomy with lower eyelid retractor plication compared to an everting sutures (ES) technique or lateral tarsal strip (LTS) procedure for the correction of lower eyelid involutional entropion.

METHODS

A nonrandomized clinical study was carried out at two tertiary eye hospitals between January 2016 and December 2019. Patients in Group A underwent triangular tarsectomy and limited orbicularis myectomy with lower eyelid retractor plication. Group B had ES, and Group C underwent a LTS procedure. All participants were operated by one surgeon and underwent 1-year follow-up.

RESULTS

A total of 78 patients in whom 84 eyelids were affected by lower eyelid involutional entropion were included in the study. The success rate was higher in Group A compared to Group B and Group C (100% vs. 86.7% vs. 95.8%; P < 0.05). Recurrence at a 1-year follow-up was noted in only four (13.3%) eyelids in Group B and one (4.2%) in Group C. However, patient's in Group C experienced a higher frequency of minimal postoperative complications, including short-term pain (100%), tenderness on the lateral canthal area (100%), tightness of the eyelid (91.7%), and ecchymosis (54.2%) compared to Group A. Patients of Group B experienced minimal or no postoperative complications.

CONCLUSIONS

Triangular tarsectomy and limited orbicularis myectomy with eyelid retractor plication may be considered the standard procedure for correcting lower eyelid involutional entropion with no recurrence compared to LTS technique or minimally invasive and cost-effective ES procedure.

Changes in Lacrimal Punctum Position and Tear Meniscus Height after Correction of Horizontal Laxity in Involutional Lower Eyelid Entropion

Purpose

To examine changes in the position of the lower eyelid punctum and tear meniscus height (TMH) after correction of horizontal laxity of the lower eyelid in involutional lower eyelid entropion.

Methods

This prospective, observational study included 42 sides of 36 patients with involutional entropion who underwent a lateral tarsal strip procedure or transcanthal canthopexy (+ lower eyelid retractor advancement). The horizontal distance from the medial margin of the lower lacrimal punctum to the medial canthus was measured using ImageJ software. TMH was measured using anterior segment optical coherence tomography. All measurements were performed preoperatively, at postoperative 3-month and at postoperative 6-month.

Results

The lower lacrimal punctum significantly shifted laterally at 3-month follow-up and slightly returned toward its original position at 6-month follow-up (Friedman's test, P  <  0.001). Although the differences did not reach statistical significance, TMH in the lower eyelid increased at 3-month follow-up and then slightly decreased at 6-month follow-up (Friedman's test, P = 0.076).

Conclusions

The results of this study imply that lateral shift of the lower lacrimal punctum prevents effective drainage of tears accumulated in the lacrimal lake, resulting in increased TMH after correction of horizontal laxity of the lower eyelid in involutional entropion.

Outcomes of Lateral Tarsal Strip in Conjunction with a Minimal Skin Muscle Excision Underlying Cauterization in Korean Patients with Involutional Entropion

We reviewed the medical records of 53 involutional entropion patients, who underwent lateral tarsal strip (LTS) with a minimal skin muscle excision by cauterization from March 2014 to December 2017, to evaluate the effectiveness and efficiency of LTS in conjunction with a minimal skin muscle excision using cautery in patients with involutional entropion. We evaluated the success rate, complications, recurrence rate, and degree of satisfaction of our technique. Of 53 patients, there were 5 bilateral cases for a total of 58 eyelids. The average of age was 71.2 years old (57–90 years). The average follow-up period was 18 months (12–39 months). The success rate for involutional entropion correction was 98.1% with our technique. There was one mild recurrence case at 7 months. In our study, the average operation time was 20.8 min (15–29 min) for 48 unilateral cases and 27.2 min (20–32 min) for 5 bilateral cases without intraoperative complications. Of 42 responders of patients’ satisfaction questionnaire, 38 patients showed good satisfaction and were willing to recommend the surgery to their acquaintances. The technique of LTS with minimal skin excision with cauterization was effective and provided satisfying outcomes to patients with involutional entropion.

Two-paired Mini-incisional Entropion Surgery for Involutional Entropion

PURPOSE

The aim of this study is to describe "2-paired mini-incisional entropion surgery" for involutional entropion.

METHODS

This study was a retrospective single-surgeon case series. Patients who underwent different entropion surgeries were reviewed. Patients with involutional entropion were divided into 3 groups according to the type of surgery performed by a single surgeon: 2-paired mini-incisional entropion surgery; transconjunctival retractor reinsertion; or transcutaneous retractor reinsertion. Patients were followed up to 35 months after the surgery. Operation time, complications, and success were compared between groups.

RESULTS

Sixty-six lower eyelids of 60 patients were evaluated. The recurrence was 7.7% in the transcutaneous group, was 5.9% in the 2-paired mini-incisional entropion surgery group, and was 5.3% in the transconjunctival group. The total chance of success in 24-month period was 94.7% in the transconjunctival approach group, was 94.1% in the 2-paired mini-incisional entropion surgery group, and was 92.3% in the transcutaneous group.

CONCLUSION

The 2-paired mini-incisional entropion surgery can be used for entropion repair alone or in combination with horizontal tightening surgeries.

A retrospective study of tailored surgery based on the mechanical balance principle for involutional entropion in the lower eyelid

OBJECTIVE

Involutional entropion in the lower eyelid is one of the most common eyelid disorders of the elderly. Despite the effectiveness of the widely used surgical procedures, recurrence rates have failed to improve. In this retrospective study, we aimed to assess surgical plans, effectiveness and safety of tailored surgery based on the mechanical balance principal in treating involutional entropion in the lower eyelid.

METHODS

A retrospective analysis of 47 patients (54 eyelids) diagnosed with involutional entropion in the lower eyelid and receiving tailored surgical treatment based on mechanical balance principle from 1 January 2016 to 31 December 2018 was carried out. Tailored surgical plans were developed according to the mechanical balance analysis of vertical, horizontal and sagittal directions.

RESULTS

All 54 eyelids with involutional entropion in the lower eyelid underwent advancement of the lower eyelid retractor (LER) through the conjunctiva. For patients with mild horizontal eyelid laxity, only LER advancement was performed. For moderate and severe horizontal eyelid laxities, combined horizontal reinforcement procedures were performed, including lateral canthopexy, lateral tarsal strip (LTS) surgery and wedge resection. The orbicularis oculi muscle (OOM) tightening or transposition was performed for OOM overriding. The follow-up time was 1 to 4 years, and there were no cases experiencing recurrence. Thus, the rates of effectiveness and recurrence were 100% and 0%, respectively.

CONCLUSIONS

This is the first descriptive study on the tailored surgical strategies designed according to the mechanism of mechanical imbalance involved in involutional entropion. Tailored surgery based on the mechanical balance principle is safe and effective with low recurrence.
