[Clinical characteristics and surgical management outcomes of glaucoma secondary to congenital ectropion uveae: a preliminary analysis of penetrating Schlemm's canaloplasty]

Objective: To investigate the clinical characteristics and treatment outcomes of glaucoma secondary to congenital ectropion uveae (CEU) using penetrating Schlemm's canaloplasty. Methods: This was a retrospective case series study. Medical records of patients diagnosed with glaucoma secondary to CEU and undergoing penetrating Schlemm's canaloplasty at the Eye Hospital of Wenzhou Medical University between August 2020 and December 2021 were collected. Clinical characteristics including the extent and location of iris ectropion, type of glaucoma, were analyzed. Follow-up visits were conducted at 1, 3, 6 months, and 1 year postoperatively. Visual acuity, intraocular pressure (IOP), anterior segment and fundus condition, filtering bleb morphology, use of IOP-lowering medications, ultrasound biomicroscopy results, and other indicators were analyzed to summarize surgical outcomes. Results: Six cases (6 eyes) of glaucoma secondary to CEU were included, all unilateral, with 3 left eyes and 3 right eyes; median age was 10.0 (5.3, 28.8) years; including 3 males and 3 females. Preoperative IOP was (31.7±10.0) mmHg (1 mmHg=0.133 kPa), and the preoperative number of IOP-lowering medications used was 2.0 (2.0, 3.2). The extent of iris ectropion in the 6 cases ranged from 270 ° to 360 °, with peripheral anterior synechiae corresponding to the location of iris ectropion, and angle closure with the degree of synechiae extending beyond Schwalbe's line. No surgical complications occurred in any of the 6 cases postoperatively. At 1 month postoperatively, the IOP was (16.4±3.2) mmHg, with a median of 0.0 (0.0, 1.5) medications used. At 3 months postoperatively, the IOP was (14.8±6.0) mmHg, with a median of 0.0 (0.0, 2.2) medications used. At 6 months postoperatively, the IOP was (18.1±6.1) mmHg, with a median of 0.0 (0.0, 0.5) medications used. Among them, 5 patients had a follow-up period of 1 year postoperatively, all achieving controlled IOP without the use of IOP-lowering medications, with an average IOP of (15.5±3.1) mmHg. No obvious filtering bleb formation was observed at the surgical site in all patients. Conclusions: Glaucoma secondary to CEU manifests primarily as closed-angle glaucoma, with a correspondence between the closure range of anterior iris adhesions in the angle and the extent of iris ectropion. Penetrating Schlemm's canaloplasty demonstrates favorable and stable efficacy for its treatment.

Combining the Tunnel Orbicularis Oculi Muscle Flap Technique With Skin Grafting for Enhanced Adhesion in Burn-Induced Ectropion Repair

PURPOSE

Scar contracture of the eyelid following facial burns often has adverse consequences. Total cicatricial contracture often makes adjustment flap translation challenging to implement. Previously used upper and lower eyelid adhesion methods are ineffective for patients with severe cicatricial contracture, and ectropion can easily recur. This study aimed to retrospectively examine upper and lower eyelid adhesions using an orbicularis oculi muscle flap and verify its stability.

METHODS

In patients with ectropion caused by severe scar contracture following head and face burns, we employed a tunnel orbicularis oculi muscle flap technique, which involved creating a tunnel between the skin and the tarsal plate of the eyelid, mobilizing the orbicularis oculi muscle, and rotating it into this tunnel to provide stable adhesion of the upper and lower eyelids. Full-thickness skin grafting was then performed. The eyelids were examined postoperatively to determine whether reoperation was necessary and to monitor for any potential complications.

RESULTS

This study included 26 patients and 46 eyes. No accidental disconnection occurred after eyelid adhesion, which lasted for an average of 21.87 ± 10.08 months before the eyelid adhesion was cut open. No complications or adverse reactions occurred, and the adhesions did not break unexpectedly.

CONCLUSIONS

Repairing eyelid ectropion with the tunnel orbicularis oculi muscle flap is a simple procedure that immediately creates tension against upper and lower eyelid contractures, providing long-term stable adhesion. This method avoids structural disorders, such as eyelid margin scarring, minimally influences surrounding tissues, and has few postoperative complications. It holds great value for repairing eyelid tissue defects and warrants further study.

Fourteen-Year Experience in Burn Eyelid Reconstruction and Complications Recurrence: A Retrospective Cohort Study

BACKGROUND

Loss of vision and other ocular defects are a concern with eyelid burn sequelae. This most commonly progresses from eyelid contracture to cicatricial ectropion and lagophthalmos. When left untreated, these may lead to exposure keratitis, ulceration, infection, perforation, and loss of vision. In the case of full-thickness eyelid burns, release and grafting are required. However, there is a paucity of studies on outcomes in eyelid burn surgery treatment, despite concern for permanent ocular damage or loss of vision. The aim of the study is to describe the complication rates in burn eyelid reconstruction at a single center for 14 years.

METHODS

A retrospective cohort study was performed of all patients who had sustained eyelid burns and required reconstruction between April 2009 and February 2023. Medical records were obtained from patients' charts. Collected data include demographics, medical history, type of injury, indication for surgery, procedure performed, and complications.

RESULTS

A total of 14 patients and 25 eyelids underwent eyelid reconstruction of the 901 total patients with burn-related injuries requiring plastic surgery reconstruction. These patients underwent 54 eyelid surgeries with a mean follow-up time of 13.1 ± 17.1 months. Patients were 71% men and 29% women, with a mean age of 45.1 ± 15.6 years. In 53.7% (n = 29) of the cases, the simultaneous reconstruction of both the upper and lower eyelids was necessary. The reconstruction of the upper and lower eyelid alone represented a smaller percentage (25.9% and 20.4%, respectively). On average, the patients received 3.9 ± 3.5 eyelid surgeries. The overall complication rate was 53.7% (n = 29). The most common complication was ectropion (42.6%, n = 23). Other complications included eye injury (25.9%, n = 14), lagophthalmos (24.1%, n = 13), local infection (7.4%, n = 4), and graft loss (5.6%, n = 3).

CONCLUSION

Periorbital burns represent a major challenge that may require complex surgical intervention. Full-thickness skin graft remains the standard of care for patients with eyelid burns. However, there is a high incidence of ectropion that may require reoperation. Further studies examining the conditions of successful eyelid burn procedures may provide guidance on when patients may benefit from eyelid reconstruction during their burn treatment.

Congenital ectropion in Noonan syndrome

Ten-year-old female patient, with facial dysmorphia, scoliosis, short stature, muscular hypotonia, patent foramen ovale and maturational delay, presented for correction of bilateral congenital ectropion. Ophthalmological examination revealed bilateral lower eyelid ectropion, euryblepharon and lagophthalmos, with a positive Bell's phenomenon. She was treated with full-thickness autologous skin grafts on the lower eyelids with bilateral lateral canthoplasty, resolving the ectropion and improving eyelid occlusion. Subsequently, a genetic study was performed that revealed a mutation in the PTPN11 gene and allowed, together with the clinical picture, to make the diagnosis of Noonan syndrome. Noonan syndrome is a multisystem genetic disorder with a wide variety of phenotypes, which usually presents with ocular and periocular disorders. Eyelid ectropion, a distinctive feature of this patient, is a rare ophthalmological manifestation of this syndrome that can be corrected with full-thickness skin graft and lateral canthoplasty.

Lateral Tarsal Strip versus Tensor Fascia Lata Sling for Paralytic Ectropion: Comparison and Long-Term Outcomes

BACKGROUND

Paralytic ectropion increases risk for corneal injury in facial palsy patients. Although a lateral tarsal strip (LTS) provides corneal coverage through superolateral lower eyelid pull, the unopposed lateral force may result in lateral displacement of the lower eyelid punctum and overall worsening asymmetry. A tensor fascia lata (TFL) lower eyelid sling may overcome some of these limitations. This study quantitatively compares scleral show, punctum deviation, lower marginal reflex distance, and periorbital symmetry between the two techniques.

METHODS

Retrospective review was performed on facial paralysis patients who underwent LTS or TFL sling surgery with no prior lower lid suspension procedures. Standardized preoperative and postoperative images in primary gaze position were used to measure scleral show and lower punctum deviation using ImageJ, and lower marginal reflex distance using Emotrics.

RESULTS

Of 449 facial paralysis patients, 79 met inclusion criteria. Fifty-seven underwent LTS surgery and 22 underwent TFL sling surgery. Compared with preoperatively, lower medial scleral show improved significantly with both LTS (10.9 mm 2 ; P < 0.01) and TFL (14.7 mm 2 ; P < 0.01). The LTS group showed significant worsening of horizontal and vertical lower punctum deviation when compared with the TFL group (both P < 0.01). The LTS group was unable to achieve periorbital symmetry between the healthy and paralytic eye across all parameters measured postoperatively ( P < 0.01); and the TFL group achieved symmetry in medial scleral show, lateral scleral show, and lower punctum deviation.

CONCLUSION

In patients with paralytic ectropion, TFL sling provides similar outcomes to LTS, with the added advantages of symmetry without lateralization or caudalization of the lower medial punctum.

Preseptal transconjunctival approach in orbital floor fracture repairs to prevent postoperative lower eyelid malposition

PURPOSE

Lower eyelid malposition can be a complication following orbital floor fracture surgeries. We present our incidence of lower eyelid malposition from a large case series of orbital floor fracture repairs using the 'swinging eyelid' approach and 'hang back' technique.

METHODS

A retrospective review of all orbital fracture surgeries at our institution from November 2011 to March 2021 was performed. Primary outcomes included the incidence of lower eyelid malposition by category, the average time to presentation after primary surgery, and reoperation rates among cases with lower eyelid complications.

RESULTS

A total of 438 cases that involved repair of the fractured orbital floor were identified. Six patients (1.37 %) developed lower eyelid malposition following primary orbital floor repair. Two patients (0.46 %) developed reverse ptosis of the lower eyelid. Two patients (0.46 %) returned with lower lid cicatricial ectropion. One patient (0.23 %) had postoperative lower eyelid retraction. One patient (0.23 %) had postoperative lower eyelid cicatricial entropion. No cases of lower lid flattening, lower eyelid fat flattening, or eyelid notch was noted. All patients with lower eyelid malposition underwent additional surgeries except one patient with reverse ptosis (83.3 %). The average time to the presentation of postoperative complications from the surgery date was 292.8 days (range = 49 days to 3.5 years).

CONCLUSION

Lower eyelid malposition after orbital floor repair is a known complication that can be decreased by employing the 'swinging eyelid' with a preseptal approach and closure by the 'hang back' technique.

The Utility of the Paramedian Forehead Flap in Lower Eyelid Reconstruction

BACKGROUND

Malignant cutaneous eyelid tumors account for approximately 10% of all cutaneous cancers. Like other cancerous skin lesions, treatment commonly involves excision with wide margins, requiring tissue reconstruction. The use of the paramedian forehead flap (PMFF) has been described for reconstruction of the medial and upper eyelid, but literature is lacking for its use in lower eyelid anterior lamella reconstruction. We present a case series of patients who underwent reconstruction of lower eyelid defects using the PMFF.

CASE PRESENTATIONS

We present 2 patients who underwent reconstruction of lower eyelid defects using the PMFF surgical technique. The patients had previous history of lower lid repair with other reconstructive methods because of cancerous eyelid lesions. In addition, both received adjuvant radiation therapy, which led to development of ectropion. Postoperative signs, symptoms, and photographs were collected to monitor outcomes.

MANAGEMENT AND OUTCOMES

Reconstructions were performed by the collaborative efforts of a facial plastic reconstructive surgeon and oculoplastic surgeon using a staged PMFF approach. Postoperatively, both patients had significant improvement in ophthalmologic symptoms, particularly ectropion and lagophthalmos. At their most recent follow-up visit, they were satisfied with their functional and aesthetic outcomes.

CONCLUSION

The PMFF may be safely used to reconstruct defects of the lower eyelid anterior lamella. In this study, the PMFF has proven to be an excellent option for patients with complications after previous lower eyelid reconstructions or history of radiation therapy. Overall, the PMFF should be considered as part of the surgeon's reconstructive ladder when addressing lower eyelid defects.

Evaluation of the Effect of Subciliary Approaches on Lower Eyelid Position in Infraorbital Rim Fractures

BACKGROUND

 Periorbital fractures are a condition encountered after high-energy trauma in the face region. In the follow-ups after surgical repair, some changes may occur in the lower eyelid. Scleral show, ectropion, entropion, and canthal malposition are the most common complications. In this study, the effect of subciliary soft tissue approaches on lower eyelid position in patients with infraorbital rim fracture was investigated.

METHODS

 Patients admitted with orbital lower rim fracture between January 2017 and January 2021 were included in the study. A total of 90 patients, 15 patients in each group, were followed up for 6 months. Before the operation, the patients were randomly assigned to the groups by an impartial observer and the surgeons who would perform the operation were informed about the method. The patients were divided into six groups according to the type of soft tissue approach for fracture repair.

RESULTS

 There were 6 groups in total and each group included 15 patients. The mean age was 41.4 in group 1, 50.6 in group 2, 38.2 in group 3, 36.4 in group 4, 38 in group 5, and 39.9 in group 6. There was no statistically significant difference between the groups in terms of age (p = 0.090), gender distribution (p = 0.835), and smoking (p = 0.685). Ectropion was observed in 14 of 73 male patients and 5 of 17 female patients. Ectropion was observed in 9 of 38 smokers and 10 of 52 nonsmokers. When all groups were evaluated together, the scleral show measurement was 0.072 on the operated side and 0.034 on the healthy side. This measurement was statistically significant (p = 0.000).

CONCLUSION

 Subciliary skin-only or step incision approaches can be used safely in the exposure of infraorbital rim fractures, but both approaches must be supported by canthopexy.

Efficacy of the Buried Temporary Suture Tarsorrhaphy: A Novel Technique

PURPOSE

To describe a buried variation of the temporary suture tarsorrhaphy and determine its efficacy period.

METHODS

This retrospective case review includes 11 patients needing corneal protection. Six patients had lagophthalmos from facial nerve palsy, 4 had cicatricial ectropion, and 1 had neurotrophic keratopathy. A total of 14 buried temporary suture tarsorrhaphies (BTSTs) were placed. The duration of the BTST was the main outcome. The corneal status before and throughout the BTST was monitored. The eyelids were examined for any undesired changes from the BTST.

RESULTS

The mean duration of the BTST was 97.5 days, with a maximum of 273 days. Aside from one spontaneous dehiscence 5 days after placement, all BTSTs held until intentional removal. Five BTSTs were removed for a more definitive surgical procedure, 6 were removed after resolution of the initial indication, and 2 are still in place as the patient awaits surgery. All cases of keratopathy improved after BTST placement. There were no complications and no undesired eyelid changes.

CONCLUSIONS

The BTST is a simple, fast, safe, and effective procedure that can be performed in the clinic or inpatient to immediately improve ocular surface coverage. As a minimally invasive procedure that can easily last several months, the BTST is an excellent option for patients who require more intense intervention than medical management alone. It can also securely bridge patients to a permanent solution such as lateral canthal resuspension.

Evaluation of outcomes of lower eyelid entropion and ectropion surgical repair

<b><br>Introduction:</b> The imbalance of external and internal forces acting on the lower eyelid can result in entropion and ectropion, both of which cause ocular irritation and loss of proper eye protection. Potential complications of untreated cases include recurrent inflammation of the conjunctiva and cornea, conjunctival neovascularization, corneal abrasion or perforation, and ultimately even loss of vision. Although various surgical techniques are used to address this problem, their long-term outcome and effectiveness are still under discussion. </br> <b><br>Aim:</b> To evaluate outcomes of surgery for entropion and ectropion, including a modified Wheeler's method for entropion correction.</br> <b><br>Methods:</b> A non-comparative study (prospective and retrospective groups) included 100 patients operated on in two university hospitals' plastic surgery departments for lower eyelid entropion or ectropion, following formal ethics approval. The prospective group included 50 patients assessed preoperatively and at 3 and 12 months postoperatively. The retrospective group was comprised of 50 patients (2012-2018), whose preoperative documentation and clinical examinations were analyzed. The main outcome measures were change between pre- and postoperative patient-reported symptoms (VAS scale), ectropion/entropion grading scale (EGS/EnGS), quality of life (WHOQOL-BREF), and occurrence of complications.</br> <b><br>Results:</b> The differences in the severity of all symptoms before and after surgery evaluated with the VAS scale were statistically significant in both groups (p <0.05). We observed 6 recurrences (12%) in the prospective group and 9 (18%) in the retrospective group, with minor complications. Very good functional and esthetic postoperative results were confirmed in 70% (79) of the whole group and in 13 patients (81.3%) treated with the modified Wheeler's method. In the prospective group, the Mann- Whitney U test for dependent variables revealed significant improvement in the somatic, psychological, and environmental domains, with no significant change in the social relationships domain.</br> <b><br>Conclusions:</b> The results following entropion/ectropion surgery prove the effectiveness of the methods used. Complementing them with the modified Wheeler's method brought an increase in the number of very good outcomes. Surgery of lower eyelid malposition contributed to reduced symptoms and improved quality of life. The rates of postoperative sequelae were low.</br>.

The surgical management and outcomes of kissing nevi of the eyelids

PURPOSE

To describe the clinical characteristics, surgical technique, and outcomes in patients with kissing nevi who underwent surgical management in two tertiary referral centers.

METHODS

Medical chart review was conducted for all patients who underwent surgical repair in Moorfields Eye Hospital and The Children's Hospital of Philadelphia. Demographics, medical history, lesion characteristics, surgical intervention, and outcomes were collected. Main outcome measures were surgical interventions as well as functional and cosmetic outcomes.

RESULTS

Thirteen patients were included. Mean age at presentation was 23.46 years (±19.35,4-61), and the mean number of surgeries per patients was 1.9 (±1.3,1-5). Initial procedure included incisional biopsy in three cases (23%) and complete excision and reconstruction in 10 cases (77%). Surgery involved the upper and lower anterior lamella in all cases, the upper posterior lamella in 4 patients (31%), and the lower posterior lamella in 2 patients (15%). Local flaps were utilized in 3 cases and grafts in 5 cases. Complications included: trichiasis (n = 2, 15%), lower eyelid ectropion (n = 2, 15%), mild ptosis (n = 1, 8%), and upper/lower punctal ectropion (n = 1, 8%). Twelve patients (92%) were satisfied with the final functional and cosmetic outcome. No recurrence or malignant transformation were observed in any patient.

CONCLUSION

The surgical management of kissing nevi can be challenging, and commonly includes the use of local flaps or grafts, often requiring multiple interventions. The approach should be based on lesion size and location, proximity and involvement of key anatomical landmarks, as well as individual facial characteristics. Surgical management has a favorable functional and cosmetic outcome in the majority of patients.

Association of topical glaucoma medications with lacrimal drainage obstruction and eyelid malposition

BACKGROUND/OBJECTIVES

Adverse effects of topical glaucoma medications (TGMs) may include development of ocular adnexal disorders. We undertook a study to determine the effect of TGMs on the risk of developing lacrimal drainage obstruction (LDO) and eyelid malposition.

SUBJECTS/METHODS

All patients 66 years of age and older in Ontario, Canada initiating TGM and all patients diagnosed with glaucoma/suspected glaucoma but not receiving TGM from 2002 to 2018 were eligible for inclusion in this retrospective cohort study. Using validated healthcare administrative databases, cohorts were identified with TGM and no TGM patients matched 1:2 on sex and birth year. The effect of TGM treatment on risk of surgery for LDO and lid malpositions was estimated using Kaplan-Meier and Cox proportional hazards models.

RESULTS

Cohorts included 122,582 patients in the TGM cohort and 232,336 patients in the no TGM cohort. Among the TGM cohort there was decreased event-free survival for entropion (log-rank P < 0.001), trichiasis (P < 0.001), and LDO (P = 0.006), and increased ectropion-free survival (P = 0.007). No difference in ptosis-free survival was detected (P = 0.78). For the TGM cohort there were increased hazards for entropion (hazard ratio [HR] 1.24, 95% confidence interval [CI] 1.12-1.37; P < 0.001), trichiasis (HR 1.74, 95% CI 1.57-1.94; P < 0.001), and LDO (at 15 years: HR 2.39, 95% CI 1.49-3.85; P = 0.004), and a decreased hazard for ectropion (HR 0.89, 95% CI 0.81-0.97; P = 0.008). No association between TGM treatment and ptosis hazard was detected (HR 0.99, 95% CI 0.89-1.09; P = 0.78).

CONCLUSIONS

TGMs are associated with an increased risk of undergoing surgery for LDO, entropion, and trichiasis.

Intraorbital Fixation Midface Lift

BACKGROUND

Subperiosteal midface lift provides a comprehensive solution to the soft tissue component of midfacial aging. However, midfacial aging also has a skeletal component that is rarely addressed with conventional mid-facelift techniques. Moreover, many of the adverse outcomes after a mid-facelift are closely related to failures and limitations of mid-face fixation. The author's technique was designed to overcome these limitations.

OBJECTIVES

The author aimed to describe the rationale, technical details, and outcomes of the author's mid-facelift technique with intraorbital fixation.

METHODS

This study was a retrospective review of 82 nonconsecutive cases where the intraorbital fixation mid-facelift was performed by the author between September 2016 and December 2021. Patient data were obtained from patient records and standardized photography. Preoperative differences in mid-face volume were assessed utilizing the Allergan midface volume deficit scale on standardized photography.

RESULTS

The average mid-face volume deficit score significantly improved after surgery. Failure of fixation, flat midface deformity, and relapse of mid-face ptosis were not seen in any of the primary patients. Infraorbital hollow did not recur in any of the patients operated on with this technique. None of the primary patients (0/58) in this series developed ectropion or permanent lower eyelid malposition.

CONCLUSIONS

Intraorbital fixation mid-face lift is an effective and durable surgical option for the treatment of midfacial aging. The technique is applicable in problem cases such as negative vector patients, negative canthal tilt patients, male patients with large bags, and secondary lower blepharoplasties where conventional techniques tend to fail.

Absorbable Suture Anchor Technique: A Method for Postblepharoplasty Lower Eyelid Ectropion Treatment

ABSTRACT

Postblepharoplasty ectropion is a very complex problem to deal with because its relevance is far to be only a functional complaint. Therefore, the best surgical approach requires both aesthetic and functional consideration. Here, we introduce the absorbable suture anchor technique, which can meet both needs, and its surgical procedure is simple and effective and has excellent stability for long-term results. This series included only ectropion patients caused by lower eyelid blepharoplasty, with or without receiving revision surgery. Forty-seven cases (64 eyes) were treated by a single surgeon through this method. Forty-six patients (97.9%) displayed adequate correction of the eyelid ectropion and a marked degree of improvement both in aesthetic terms and with regard to the functional disorders reported. One patient (2.1%) presented complications but brought under control after drainage and dressing change. His previous symptoms were also largely relieved. Absorbable suture anchor technique is an effective, minimally invasive, and safe method to correct postblepharoplasty ectropion.

Lateral Tarsoplasty for Managing Ectropion and Laxity of the Lower Eyelid

BACKGROUND

The most challenging complication associated with lower blepharoplasty is ectropion, and the traditional lateral canthopexy or canthoplasty procedure may carry the risk of eyelid malposition or subsequent chemosis. We propose lateral tarsoplasty with a detailed description of the techniques to treat and even prevent ectropion by not involving the medial or lateral canthal ligament so as to avoid complications.

MATERIALS AND METHODS

Lower eyelid laxity was analyzed with the snap-back test and distraction test before surgery. Approximately 5 mm medial to the lateral canthus, lateral tarsoplasty is performed through a full-thickness pentagonal tarsal-conjunctival resection according to the "overlapping test" for an accurate measurement of the amount of the tarsus to be resected. Seventy-two eyelids that received either ectropion correction or prevention with lateral tarsoplasty over an 8-year period at a single institution were collected and analyzed for this retrospective review.

RESULTS

Lateral tarsoplasty was performed in 39 patients with a mean age of 63.8 years. Thirteen patients with 20 eyelids presented for ectropion correction, in whom 5 to 10 mm of tarsus was resected, 6.0 mm in average. The other 26 patients with 52 eyelids presented for ectropion prevention, in whom 3 to 7 mm of tarsus was resected, 4.1 mm in average. Apart from temporary mild chemosis, all patients experienced highly satisfactory results without any ectropion or malposition of the involved lower eyelids after a follow-up of 8.1 months in average.

CONCLUSIONS

For patients with moderate and severe laxity of lower eyelids, lateral tarsoplasty without involvement of the lateral canthal ligament proves to be an effective way to treat and prevent lower eyelid ectropion.

Burn Scar Ectropion Correction: Surgical Technique for Functional Outcomes

BACKGROUND

Eyelid scarring after severe burn injury of the face is a significant complication endangering vision in addition to the burn scar sequelae. Scar contraction leads to asymmetry and malposition of the eyelid axis, resulting in corneal exposure, eyelid retraction, and incomplete eyelid closure. In consequence, dryness and irritation of the cornea can lead to keratitis, corneal opacity, and vision impairment. In this study, we present our surgical technique for lateral canthopexy in combination with full-thickness skin grafting (FTSGing) in patients with eyelid axis distortion after scar contraction of the periorbital region after severe burn injuries of the face.

METHODS

In this retrospective, single-center case study, we present 5 consecutive patients who experienced severe burn injuries to the face between 2014 and 2019. Patients were suffering from ectropion and malposition of the eyelid axis. In all cases, we performed lateral transosseous canthopexy and FTSGing.

RESULTS

Improved symmetry and complete eyelid closure were restored in all 5 patients. The following ophthalmological examinations showed resolved corneal erosions, as well as reduction of chemosis and epiphora. Further vision impairment was successfully prohibited. Surgical revision with FTSGing was required in 2 patients because of recurrence of unilateral lower eyelid retraction.

CONCLUSIONS

Lateral transosseous canthopexy represents a suitable surgical method to durably correct eyelid malposition, ectropion, and incomplete lid closure in patients with severe scarring of the periorbital region after burns of the face. Early detection of patients at risk and timing of surgical intervention are of great importance.

Inferiorly Based Rotation Flaps for Infraorbital Cheek Defects

BACKGROUND

The infraorbital cheek is a common location for cutaneous malignancy and thus surgical defects. Reconstruction in this region must maintain nearby free margins to ensure optimal cosmetic and functional outcomes. Large defects may require a flap using lateral or inferior tissue reservoirs.

OBJECTIVE

To examine outcomes of inferiorly based rotation flaps in the repair of infraorbital cheek defects and highlight pearls for optimal long-term results.

METHODS

Chart review of patients with a defect of the infraorbital cheek repaired with an inferiorly based rotation flap between February 2010 and December 2018 at a single academic institution. The Visual Analog Scale (VAS) was used for scar assessment.

RESULTS

Sixty-five patients underwent extirpation of a cutaneous malignancy resulting in defects ranging from 1.0 × 1.0 to 4.5 × 5.5 cm (mean area = 4.8 cm2). Most of the patients did not experience complications. Ectropion occurred in 7 patients. The mean VAS score was 11.6.

CONCLUSION

An inferiorly based rotation flap yields acceptable outcomes for infraorbital cheek defects and can be considered for defects as large as 5.5 cm. Using pearls for surgical execution presented in this article may allow reconstructive surgeons to include this flap in their repertoire.

Sight-threatening Complication of Cicatricial Ectropion in a Patient with Lamellar Ichthyosis - Case Report

We report a case of lamellar ichthyosis and sight-threatening complications of cicatricial ectropion in an adult male patient which was surgically managed with tectonic penetrating keratoplasty. We present a case of autosomal-recessive lamellar ichthyosis in a 47-year-old man who was referred to our outpatient eye clinic for treatment of primary keratouveitis of the right eye with keratolysis and exudation in the anterior chamber. A diagnosis of cicatricial ectropion with serious lagophthalmos was established on examination. The patient underwent tectonic penetrating keratoplasty, cataract extraction, and intra-ocular lens placement with no perioperative complications. The patient was subsequently treated with oral fluconazole 200 mg once daily for 12 days due to a positive fungal culture for Candida albicans and systemic oral acyclovir 250 mg 3 times per day for 12 days as prophylaxis for a labial herpetic infection. Post-operative complications included corneal rejection and nonhealing neurotropic epithelial defect of the graft. Long-term treatment with topical cyclosporine (Ikervis®) and dexamethasone led to resolution of the corneal rejection. Lubrication with artificial tears containing hyaluronic acid, perfluorohexyl octane (Evotears®), and vitamin A ointment led to symptomatic relief of dry eye disease. The patient was referred to a dermatologist and was started on systemic retinoid acitretin at a dose of 0.5 mg/kg per day. Ten months after surgery, the patient's visual acuity was 0.1 based on the Snellen chart and the corneal graft was stable. Infection in the cornea can rapidly progress to corneal melting in patients with severe cicatricial ectropion. A good patient outcome depends on the interdisciplinary approach to patient management by the ophthalmologist, dermatologist, and plastic surgeon.

Non-Classic Signs of Sézary Syndrome: A Review

The majority of patients with Sézary syndrome (SS) present with classic symptoms of erythroderma, lymphadenopathy, and pruritus. However, there have been numerous reports of patients with SS who have non-classic signs. In this review, we report the less common clinical presentations of SS and discuss their relevant treatments. Our search included all literature on SS since 2008, the year the World Health Organization (WHO) incorporated the diagnostic criteria for SS into the WHO Classification of Tumours of Haematopoietic and Lymphoid Tissues. We reviewed 896 articles and identified 505 patients with non-classic presentations of SS. Of these 505 patients, the most common non-classic signs of SS were keratoderma, onychodystrophy, alopecia, leonine facies, and ectropion. Given the aggressive and highly symptomatic nature of SS, it is imperative that clinicians recognize the less common signs of the disease to prevent delays in diagnosis and treatment. To our knowledge, this is the first review of the clinical variations of SS with a focus on non-classic signs and symptoms.

The bicycle wheel analogy for linear closures of small suborbital cheek defects

Primary closure of suborbital skin defects can cause tension along the closure resulting in ectropion. The bicycle wheel analogy is a simple yet effective guide to aid in reducing tension vectors resulting in ectropion.

Eyelid Malpositions after Cataract Surgery

Purpose.

To estimate the incidence and the factors that may play a role in the etiology of eyelid malpositions after cataract extraction.

Methods.

We followed up 124 patients for six months after cataract extraction. Palpebral aperture, levator function, height of the upper lid crease, lower eyelid laxity and position of the punctums were recorded preoperatively and postoperatively. Post-cataract ptosis was defined as a 2 mm or greater drop in the lid margin after correcting for any change in the fellow eye.

Results.

None of the patients developed ectropion or entropion, but five (4%) developed punctal ectropion after surgery. The incidence of post-cataract ptosis was 7.3% at six months. Age, sex, preoperative measurements of levator function, lid crease and dermatochalasis were not predictive for the development of ptosis at six months. However, there was a significant difference in the preoperative palpebral fissure width between the patients with ptosis and those without (p<0.05). There was a positive correlation between the mean volume of local anesthetic and the degree of ptosis on the first postoperative day (p<0.05, r: 0.1873). The presence and amount of ptosis on the first postoperative day was the best predictor of post-cataract ptosis at six months (p<0.001).

Conclusions.

Several factors are involved in the development of post-cataract ptosis. Temporary ptosis may be related to the myotoxicity of the local anesthetic. The presence of ptosis on the first postoperative day is the best predictor for the development of ptosis at six months.

"The influence of orbital vector on involutional entropion and ectropion"

PURPOSE

This study aimed to evaluate the effect of orbital vector and other biometric parameters (i.e. axial globe length, axial globe projection) on the development of involutional entropion or ectropion.

METHODS

In this cross-sectional study, 167 eyes from 132 patients were included. Of these eyes, 128 had involutional entropion and 39 had involutional ectropion, all of lower lids. The axial globe projection was measured using Hertel exophthalmometry; axial globe length was assessed by A-mode ultrasound; and orbital vector was determined clinically. Patient-specific categorical variables and continuous variables were compared using the chi-square test and the two-sided t test, respectively. Correlations were derived using the Pearson correlation.

RESULTS

The percentage of females was 59% and 33.3% in the entropion group and in the ectropion group, respectively. A significant association was found between the gender and type of eyelid malposition (p = 0.015). Exophthalmometry reading was greater in the ectropion group than in the entropion group (17.7 ± 2.5 versus 10.8 ± 3.7 mm, respectively; p < 0.001). There was no significant correlation between axial globe length and exophthalmometry reading. Positive orbital vectors were observed in 87.5% of eyelids with involutional entropion. Negative orbital vectors were observed in 92.3% of eyelids with involutional ectropion (p < 0.001). Patients with negative orbital vectors showed greater axial globe projection than patients with positive orbital vectors (18.0 ± 2.1 versus 10.6 ± 3.5 mm, respectively; p < 0.001).

CONCLUSIONS

There is an association between orbital vector measurement and involutional entropion and ectropion. Measuring the orbital vector may help predict the development of these lid malpositions.

[Clinical, epidemiological and etiological studies of adult aseptic meningitis: Report of 11 cases with varicella zoster virus meningitis]

We treated 11 cases (52.7 ± 14.9 years, all male) with varicella zoster virus (VZV) meningitis and 437 cases with adult aseptic meningitis from 2004 to 2016. The incidence rate of adult VZV meningitis in the cases with aseptic meningitis was 2.5%. Herpes zoster infections are reported to have occurred frequently in summer and autumn. VZV meningitis also occurred frequently in the similar seasons, in our patients. The diagnoses were confirmed in 9 cases with positive VZV-DNA in the cerebrospinal fluid and in 2 cases with high VZV-IgG indexes (> 2.0). For diagnosis confirmation, the former test was useful for cases within a week of disease onset, and the latter index was useful for cases after a week of disease onset. Zoster preceded the meningitis in 8 cases, while the meningitis preceded zoster in 1 case, and 2 cases did not have zoster (zoster sine herpete). Two patients were carriers of the hepatitis B virus, 1 patient was administered an influenza vaccine 4 days before the onset of meningitis, and 1 patient was orally administered prednisolone for 2 years, for treatment. Their immunological activities might have been suppressed. The neurological complications included trigeminal neuralgia, facial palsy (Ramsay Hunt syndrome), glossopharyngeal neuralgia, and Elsberg syndrome. Because the diseases in some patients can become severe, they require careful treatment.

Lower eyelid complications associated with transconjunctival versus subciliary approaches to orbital floor fractures

PURPOSE

The aim of this study was to compare the frequencies of lower eyelid complications after subciliary versus transconjunctival approaches to orbital floor fractures.

MATERIALS AND METHODS

The investigators implemented a retrospective cohort study and enrolled a sample composed of subjects who had orbital floor repair. The predictor variable was surgical approach, classified as subciliary or transconjunctival. The primary outcome variable was postoperative lower eyelid complications (ectropion, entropion, and eyelid retraction). Other variables were demographic, anatomic, or time to surgery. Descriptive and bivariate statistics were computed. Statistical significance was set at P ≤ 0.05.

RESULTS

The study samples were composed of 346 patients (98 [28.3%] females; 225 [65%] underwent a subciliary approach) with a mean age of 42.7 ± 21.1 years. The subciliary approach was significantly linked to the higher rates of ectropion and the lower rates of entropion at 7 days and 6 months postoperatively. There was no statistically significant difference in the frequency of eyelid retraction between both groups.

CONCLUSIONS

In the setting of orbital floor fractures, these results suggest that the use of the subciliary approach increases the frequency of ectropion, while the transconjunctival approach increases the frequency of entropion. The authors decline to comment on what the better surgical approach to the orbital floor fractures is. The selection should be based on an individual patient basis and surgeon's preference.

Syndrome de blépharophimosis: une forme particulière du ptosis congénital

Le syndrome de blépharophimosis est une malformation palpébrale congénitale caractérisée par l'association d'un ptosis majeur bilatéral à d'autres anomalies palpébrales. Il constitue une forme particulière du ptosis congénital qui doit être connue par tout ophtalmologue afin d'optimiser la prise en charge des patients présentant cette affection.

Management of cicatricial ectropion secondary to pyoderma gangrenosum

Pyoderma gangrenosum is a rare condition with few cases of eyelid involvement reported in the literature. Pathergy is a well-recognised phenomenon that can trigger this condition. Pyoderma gangrenosum should be considered in cases of progressive cribriform cicatrisation where there is a history of antecedent trauma. Surgical management of a resultant ectropion may be challenging as a result of aggressive scarring and the risk of provoking a recurrence. We report a case of pyoderma gangrenosum causing a cicatricial ectropion, and discuss the underlying aetiology of iatrogenic incitement, and its implications for surgical management.

[Combination of high porous polyethylene lower eyelid spacers and lateral tarsal-strip procedure for reconstruction of eyelid closure function in paralytic lagophthalmus after facial palsy]

OBJECTIVE

To evaluate the effectivness of using high porous polyethylene lower eyelid spacers (Medpor LES) combined with the lateral tarsal-strip procedure for reconstruction of the eyelid closure function in paralytic lagophthalmus after facial palsy.

METHODS

Between March 2008 and December 2012, 32 patients (32 eyelids) with hypophasis in facial palsy which all sorts of causes lead to were treated with Medpor LES combined with the lateral tarsal-strip procedure. Of 32 cases, 20 were male and 12 were female, aged from 20 to 72 years (mean, 46.8 years). The left eye was involved in 18 cases and the right eye in 14 cases with a disease duration of 1.5 months to 2 years (mean, 4.4 months). All the patients were shown as lower eyelid ectropion, lower eyelid retraction, exposure keratitis, and corneal ulcer, but no obvious upper eyelid retraction was observed.

RESULTS

Primary healing of incision was obtained in all patients. The edema time of the eyelid was from 5 days to 3 weeks (mean, 2 weeks). Conjunctival edema appeared in 4 cases after 2 weeks of operation, which was cured after expectant treatment. The patients were followed up 5-8 months (mean, 6 months). At 1 week, 3 and 6 months after operation, the height of palpebral fissure was reduced, and the degree of lagophthalmus and low eyelid retraction were significantly corrected (P < 0.05), but no significant difference among different time points after operation (P > 0.05). Outer canthus displacement occurred in 3 cases at 1 month postoperatively, and was cured after the lateral tarsal strip procedure. No lower eyelid ectropion, corneal exposure, or Medpor LES displacement and exposure occurred during follow-up.

CONCLUSION

Medpor LES combined with the lateral tarsal-strip procedure has good effectiveness for reconstruction of eyelid closure function in most cases of paralytic lagophthalmus after facial palsy.

Orbital myxoma: a case report

Orbital myxomas are extremely rare tumors. We describe a 75-year old male patient with lower eyelid ectropion and 8-mm of left non-axial proptosis. Orbital CT and MRI revealed a well-demarcated lesion in the lateral quadrant of the orbit. After complete surgical excision, histopathological examination led to the diagnosis of orbital myxoma. The patient was followed-up for 1 year without recurrence.

Levator-Muller's muscle recession with tarsorrhaphy: a technique for corneal protection in cases with cicatricial upper eyelid retraction

AIMS

Cicatricial upper eyelid retraction with exposure keratopathy and impending corneal perforation requires prompt intervention. Standard procedures such as isolated levator recession, botulinum toxin, and lid weights will only induce a partial ptosis. Conventional tarsorrhaphy, though ideal to achieve complete closure, is likely to result in dehiscence in these cases. We describe a one-stage technique of levator and Muller's muscle recession combined with a tarsorrhaphy used in four patients with an impending corneal perforation due to cicatricial lagophthalmos.

METHODS

This is an interventional, non-comparative retrospective case series of four patients who had undergone tarsorrhaphy in combination with levator recession.

RESULTS

In all four cases, it was not possible to mechanically close the eyelids preoperatively due to cicatricial lid retraction involving the middle lamella. The aetiology for lagophthalmos was varied: (Case 1) bilateral sclerosing metastatic breast cancer involving the lids; (Case 2) severe anterior and middle lamella shortening due to actinic changes; (Case 3) middle and posterior lamella shortening due to glaucoma treatment and multiple surgery (Case 4) due to traumatic facial scarring and seventh nerve palsy. In all cases, the corneal thinning and epithelial defects resolved completely following surgery. In one case, we were able to partially reopen the tarsorrhaphy for further corneal surgery.

DISCUSSION

We describe a safe, effective and reversible surgical procedure for managing cases with cicatricial upper eyelid retraction, which would otherwise lead to serious corneal complications.

Eyelid ectropion caused by glasses. Mechanical centurion syndrome

CASE REPORT

A 73 year-old woman with epiphora and ocular irritation resistant to medical treatment. The lacrimal pathway was permeable and there was no eyelid malposition. On examining the patient with her glasses on, both lower eyelids presented an inner third ectropion. Once the diagnosis was established and the mechanical factor resolved, the clinical symptoms improved within a few days.

DISCUSSION

The diagnosis of the eyelid ectropion can be more complex when the ectropion is secondary to wearing glasses. The presence of the epicanthic fold shows the importance of the mechanical factor. In our patient the characteristics of the ectropion were similar to the so-called centurion syndrome.

Marked bilateral lower eyelid ectropion in cutis laxa: a paraneoplastic process in multiple myeloma

PURPOSE

To describe a bilateral involutional lower eyelid ectropion in a patient with cutis laxa, a paraneoplastic process in multiple myeloma.

DESIGN

Case report.

RESULTS

A 60-year-old male presented with a marked involutional left lower eyelid ectropion. Systemic history included cutis laxa, a paraneoplastic feature of multiple myeloma. After surgical treatment, the ectropion recurred; furthermore, a right lower eyelid ectropion developed. In addition, a distinct dermatochalasis of both upper eyelids was present.

CONCLUSIONS

This case is the first description of a marked bilateral involutional ectropion in cutis laxa acquisita.

Bilateral lagophthalmos in leprosy: is it a rare phenomenon?

Lagophthalmos is one of the well known complications of leprosy due to involvement of the facial nerve. Herein, we report three cases of bilateral lagophthalmos due to leprosy which presented to us within a span of just three months. In all these cases, lagophthalmos was not the presenting complaint and it was detected by the treating doctor during examination. This report is being presented to highlight the importance of cranial nerve examination in all cases of leprosy as at times early changes of lagophthalmos may go unnoticed by the patient.

Diagnosis and management of palpebral anthrax

Anthrax is an infectious disease that is not well known by ophthalmologists. In its cutaneous form, it may produce lesions of the eyelids. We report eight cases of palpebral anthrax. All patients presented with a black necrotic eschar and a tegumentary edema, with a history of contact with sick animals. The curative treatment was based on intravenous penicillin G in four cases and amoxicillin-clavulanic acid in the four other cases. The palpebral lesions resolved, leaving no clinical evidence of eyelid abnormalities in six patients. Only two patients developed a cicatricial ectropion and a palpebral symphysis. Although palpebral anthrax is a rare disease in humans, ophthalmologists should be aware of its symptoms and management.

Antibodies against calsequestrin and type XIII collagen are good markers for chronic upper eyelid retraction

PURPOSE

Chronic upper eyelid retraction is a common manifestation of thyroid-associated ophthalmopathy (TAO) but can occur as a dominant feature of ophthalmopathy in patients with Graves' hyperthyroidism and in association with Hashimoto's thyroiditis in the absence of other eye signs except mild proptosis.

METHODS

We measured antibodies against calsequestrin, flavoprotein (Fp), G2s, and collagen XIII in an enzyme-linked immunosorbent assay (ELISA) in 15 patients with chronic upper eyelid retraction.

RESULTS

Calsequestrin antibodies were detected in 67% of patients with upper eyelid retraction, Fp antibodies in 47%, G2s antibodies in 20%, and collagen XIII antibodies were detected in 40% of these patients at the first visit. These prevalences were significantly greater than normal for calsequestrin and collagen XIII, but not for Fp and G2s antibodies. On follow-up, calsequestrin antibodies were detected in two more patients, for an overall prevalence of 80%. Levels of the four antibodies remained fairly constant over the study period and generally correlated with the presence and severity of upper eyelid signs.

CONCLUSIONS

These findings support the notion that autoimmune attack against calsequestrin and collagen XIII in the levator palpebrae superioris (LPS) muscle may play a role in the pathogenesis of upper eyelid retraction and that lid retraction may be the dominant feature of ophthalmopathy in patients with Hashimoto's thyroiditis and non-autoimmune thyroid disease. Because calsequestrin is an intracellular protein, the corresponding autoantibodies probably do not initiate LPS muscle inflammation but may contribute to its damage. The mix of antibodies against calsequestrin and collagen XIII may shed light on the diverse presentations found in thyroid-associated ophthalmopathy.

The role of botulinum toxin in correcting frontalis-induced eyelid pseudo-retraction post ptosis surgery

We report a case of a 52-year-old female patient who developed overcorrection, due to brow overuse, post surgery for bilateral aponeurotic ptosis. The patient had undergone levator palpebrae superioris plication bilaterally. Due to brow overuse habituated by long standing ptosis, the patient presented with superior scleral show, post ptosis surgery. The lid contour was normal in both eyes and when brow overaction was blocked mechanically, the palpebral fissure heights were normal, comparable, with no scleral show bilaterally. Despite repeated instructions, when the patient continued brow overuse subconsciously, an injection of botulinum toxin was given just above both brows. This led to elimination of brow overuse within a month, with elimination of superior scleral show. The patient maintained lid and brow symmetry with no overaction, eight months post injection.

Reconstruction of Traumatic Orbital Floor Fractures With Resorbable Mesh Plate

Various materials such as autogenous bone, cartilage and alloplastic implants have been used to reconstruct orbital floor fractures. A new material is needed because of disadvantages of nonresorbable alloplastic materials and difficulties in harvesting autogenous tissues. In this study safety and value of the use of resorbable mesh plate in the treatment of orbital floor fractures are discussed. Between 2002 and 2004 a total of 17 maxillofacial trauma patients complicated with orbital floor fractures were treated with resorbable mesh plate through subciliary or transconjunctival incisions. Pure blow-out fractures were determined in 6 patients and 11 patients had accompanying maxillofacial fractures. Resorbable plate was easily shaped to fit to the orbital floor by cutting with scissors. Patients were evaluated clinically and with computed tomography scans preoperatively and at 3-, 6- and 12-month intervals postoperatively. Twelve patients had preoperative enophthalmos. Two patients had diplopia that was corrected postoperatively. In all 17 cases there was no evidence of infection, diplopia and gaze restriction postoperatively. Scleral show appeared in three patients by the second postoperative week but resolved totally within 3 to 6 weeks except one patient. In this patient anterior displacement of mesh was evident which caused ectropion and enophthalmos and required re-operation. No any other mesh related problems were seen at 15 months mean follow-up time. The advantage of the resorbable mesh system in orbital floor fracture is the maintenance of orbital contents against herniation forces during the initial phase of healing and then complete resorption through natural processes after its support is no longer needed. Our experience represents that resorbable mesh is a safe and effective material for reconstruction of the selected, non-extensive orbital floor fractures.

Bipedicle orbicularis oculi flap in the reconstruction of the lower eyelid ectropion

BACKGROUND

Lower eyelid ectropion is conventionally reconstructed with a local flap or full-thickness skin graft. However, scar contracture and recurrence of ectropion often occur. This article describes an effective surgical technique for lower eyelid ectropion repair using a bipedicle orbicularis oculi muscle or myocutaneous flap from the upper eyelid.

METHODS

This study prospectively analyzed collected data on the bipedicle orbicularis oculi muscle or myocutaneous flap from the upper eyelid in reconstruction of lower eyelid ectropion between 1995 and 2004. The flap was used in 12 eyelid procedures for the correction of lower eyelid ectropion, in 10 cases with traumatic ectropion, and in 1 case with bilateral congenital ectropion. In these cases, a strip of orbicularis oculi muscle or a myocutaneous flap from the upper eyelid with two pedicles attached in the medial and lateral canthus was advanced to the lower eyelid to suspend the eyelid and repair the skin defect.

RESULTS

No problem of flap viability was encountered in any of the patients, and all healed well. Deformities were corrected, and evaluation showed satisfactory function and appearance during 0.5 to 6 years (average, 2 years) of follow-up evaluation. Eyelid malposition and bulkiness of the lower eyelid occurred in the early stages, but disappeared gradually about 3 months after the operation. There was no flap contraction, recurrent deformity, or significant donor site morbidity in the follow-up period. The incision scars were almost invisible.

CONCLUSIONS

The application of bipedicle orbicularis oculi muscle or a myocutaneous flap from the upper eyelid in reconstruction of lower eyelid ectropion is effective and reduces postoperative morbidity.

[Repairing of upper cicatricial ectropion with orbicularis oculi myocutaneous flap in construction of double eyelid]

OBJECTIVE

To investigate a method for upper cicatricial ectropion correction using a rotated orbicularis oculi myocutaneous flap in the unsatisfied pre-operative construction of double eyelid.

METHODS

In construction of double eyelid, orbicularis oculi myocutaneous flap made by relaxed skin and orbicularis oculi was used to correct ectropion.

RESULTS

From Feb. 2003 to Dec. 2005, the authors performed correction of ectropion for 13 patients. All of these patients were followed up, and the period ranged from 2 weeks to 6 months. All of these patients received good results except one. It was corrected again for the flattening of the pedicle 6 months later.

CONCLUSIONS

Orbicularis oculi myocutaneous flap has a rich blood supply. The ratio of its length and width can be made to 6:1, and it can be transferred flexibly. In addition, the incision of the donor site is hidden in fold of double eyelid.

Management of lower lid ectropion

BACKGROUND

Ectropion repair is a challenge in plastic surgery. Depending on the etiology of the underlying problem, a variety of surgical techniques are available. The etiology, operative management, and recurrence rate are presented.

OBJECTIVE

An improvement of the deformity or, in the ideal case, a functional and aesthetic restoration should be accomplished.

MATERIALS AND METHODS

In this study, 58 patients with ectropion treated from June 2002 until March 2004 were analyzed, 33 with scar contractures, 13 with a tumor of the lid margin, 8 with facial paralysis, and 4 with senile ectropion. Surgical procedures included lateral or medial canthopexy, lateral tarsorrhaphy, wedge excision, skin graft, local flaps, cartilage graft, fascial slings, and combined procedures in one-third of the patients.

RESULTS

Postoperative complications included incomplete correction and others in 18.9% of the patients. Eight patients (13.8%) had to be reoperated.

CONCLUSION

Correction of the lower lid area including restoration of the lid margin in terms of shape and position is the surgical end point. The preoperative analysis is mandatory for a surgical solution to this severe problem, which is associated with a high incidence of recurrence, especially in difficult reconstructive cases. An individual sophisticated strategy combined with experience in the variety of surgical techniques is mandatory. Frequently, multiple procedures are necessary.

Long-term outcomes of ultra-thin porous polyethylene implants used for reconstruction of orbital floor defects

PURPOSE

The objective of this article is to present the long-term outcomes of ultra-thin polyethylene implants used for orbital floor reconstruction in facial trauma patients.

MATERIALS AND METHODS

From 1998 to 2004, 38 patients underwent orbital floor reconstruction with porous polyethylene implants with a mean follow-up of 4 years. A subciliary incision and preexisting facial wounds or scars were used. The boundaries of the maxillofacial injury and the orbital volumes of both orbits were assessed by computed tomography images obtained pre- and postoperatively. In all patients, ultra-thin porous polyethylene implants in various sizes were used to reconstruct the orbital floor defect.

RESULTS

None of the patients needed removal of the implants during the follow-up. The volume increase of the traumatized orbits ranged from 0.04 to 6.18 (average 3.12 +/- 1.48) mL compared with the intact orbit (P < 0.01). This difference was not significant postoperatively (P > 0.01). Postoperative ectropion in three cases was corrected under local anesthesia. Persistence of complications were as follows: enophthalmos, 3 in 28; diplopia, 1 in 16; dystopia, 1 in 4; and infraorbital nerve hypoesthesia, 3 in 31. One patient underwent late enucleation of the globe because of initial penetrating trauma.

CONCLUSIONS

We recommend the use of ultra-thin porous polyethylene implants in the reconstruction of the orbital floor defects in facial trauma patients. The implants are durable in the long-term and mimic the anatomy of the thin orbital floor and avoid the morbidity of autogenous bone grafts.

[Bipedicle myocutaneous flap for cicatricial ectropion correction]

PURPOSE

To evaluate the correction of lower eyelid cicatricial ectropion due to shrinking of anterior lamela with the surgical technique of bipedicle myocutaneous flap from the upper eyelid.

METHODS

Prospective study with eight eyelids of six patients. There were two patients with unilateral ectropion who had received external local radiotherapy.

RESULTS

There were three male and three female patients, with mean age of 72 years. One patient presented an incomplete blinking for one month that spontaneously resolved. Three eyelids of two patients maintained a residual ectropion; one of them had received local external radiotherapy. Follow-up ranged from 19 to 23 months (mean of 20 months) and all patients improved their ocular condition.

CONCLUSION

The bipedicle myocutaneous flap is effective for correction of cicatricial ectropion due to shrinking of anterior lamella.

Anterior Lamella Actinic Changes as a Factor in Involutional Eyelid Malposition

PURPOSE

We conducted a noncomparative, retrospective chart review of 45 patients and 51 eyelids with the diagnosis of involutional entropion or ectropion that underwent full-thickness lower eyelid shortening between June 2001 and February 2004, in whom the severity of actinic damage was analyzed in relation to the eyelid position. Patients with any different surgical approach or other primary causes of abnormal eyelid position, such as paralytic, congenital, or mechanical factors, were excluded.

METHODS

After excision, all eyelid specimens were examined by a single anatomic pathologist, who was masked to the type of eyelid malposition. The extent of dermal actinic change was evaluated under light microscopy, according to a previously validated grading system.

RESULTS

Fifty-one eyelids from 26 male and 19 female patients were analyzed. The mean age at the surgery was 76 +/- 10 years (range, 52 to 92 years), affecting one side in 39 cases and both sides in 6 cases. The most frequent eyelid malposition was ectropion, which affected two thirds of the cases (35 eyelids). Half of the patients presented with mild actinic skin changes; however, the severity of the histologic skin actinic changes was significantly worse in patients with ectropion in comparison to those with entropion (p < 0.0001).

CONCLUSIONS

Actinic damage affecting the anterior lamella of the lower eyelid contributes as an additional factor in final eyelid position in patients with involutional eyelid changes. More severe and extensive actinic changes were present in eyelids with ectropion.
