Guidelines for reconstruction of the eyelids and canthal regions

[Paramedian frontal clefts or superior orbital clefts]

Superior orbital frontal clefts are one of the rare craniofacial clefts described by Tessier in 1976, and occur most often sporadically. They are numbered 9, 10 and 11 in this classification, and are located respectively laterally, in the middle and medially to the upper part of the orbit. Their clinical expression is variable on soft tissue and bone, with possible dissociation of involvement. They range from a simple aesthetic defect to an eyes functional prognosis. CT scans are systematically required in this context. Their management must be adapted to the polymorphism of the damage, and is based on multidisciplinary approach. In case of ocular risk, the eyelid reconstruction is an emergency. In all other cases, treatment is deferred, but must be carried out at an early stage to ensure the child's healthy development.

Customized Reconstruction of Lower Eyelid Defects

BACKGROUND

A lower eyelid defect is a loss of skin, muscle, and underlying structures that can occur due to trauma, malignant or benign tumors, burns, or other causes. The conventional surgical treatment of lower lid defects has several limitations, including visible scarring, narrowing of the eye, and ectropion. Here, we combined the use of a customized mid-face lift with a free mucochondral graft to overcome the disadvantages of existing methods.

METHODS

Forty patients underwent reconstructive surgery using a customized mid-face lift with or without a free mucochondral graft for a lower lid defect between April 2013 and October 2020. Patients were discharged shortly after surgery and were expected to visit the outpatient clinic periodically for 12 months.

RESULTS

The causes of lower eyelid defects were malignancy, trauma, foreign body granuloma, and other causes. Four patients reported complications, including 2 cases of chemosis, 1 case of a hematoma, and 1 case of corneal abrasion, who reportedly performed well after 2 weeks of conservative therapy. No patient required revision during the average follow-up period.

CONCLUSIONS

Customized reconstruction demonstrated a better aesthetic reconstruction of the lower eyelid. This method represents a good option for reconstructing lower lid defects.

Management of eyelids' primary malignancies

Purpose: We report our experience in surgical management of primary malignant tumors of the eyelids. We have specified the various surgical techniques used, as well as functional and anatomical results.Patients and methods: A review of patients admitted for malignant tumor of the eyelids in the oculoplastic department of the Hedi Raies Institute of Ophthalmology from January 2012 to December 2021.Results: One hundred and twenty-three patients with malignant eyelid tumors were hospitalized. Surgical treatment involved 114 tumor lesions, which represents 95% of the cases. One hundred and eleven lesions (97.4%) had been operated by simple tumor resection. Safety margins were, respectively, 4 mm in 63.2% and from 5 to 6 mm in 34.2%. Extemporaneous histological examination was performed in three cases (2.6%). Reconstruction involved the anterior lamella (AL) in 92 cases (80.7%), the posterior lamella (PL) in 66 cases (57.9%), the medial canthus in 18 cases (15, 8%), and lateral canthus in 4 cases (3.5%). The excision was oncological in 85 cases (74.6%) and incomplete in 19 cases (16.7%). Tumor recurrence occurred in seven cases (6.1%), after an average delay of 36 months.Conclusion: The anatomical and functional features of the eyelids require a good reconstruction of the transfixion eyelid defect. Many reconstruction methods are available, allowing extensive and complex palpebral repairs. Oncologic prognosis is conditioned by the surgical quality.

A new skin flap from the zygomaticotemporal region: Anatomical study and clinical application to eyelid reconstruction

BACKGROUND

Eyelid reconstruction is a demanding task faced by plastic surgeons. Island flaps from the zygomaticotemporal region, where the zygomatico-orbital artery predominates in vascularization, represent the recent local approaches to this problem. Questions exist as to where and on what element the flap should be based, and whether or not they should be adapted in relation to the behavior of the zygomatico-orbital artery.

METHODS AND MATERIALS

A total of 22 fresh-frozen adult cadaver heads were employed. The fasciocutaneous perforators of the zygomatico-orbital artery and their anastomoses with the surrounding arteries, especially those in the upper palpebra, were investigated. On this basis, a distally based perforator flap was created and executed for eyelid reconstruction in 7 patients.

RESULT

The zygomatico-orbital artery was interconnected through its perforators with the subdermal plexus over the zygomaticotemporal region and with the arteries in the surroundings. The transverse facial artery took the place of zygomatico-orbital artery where it was absent. Both the arteries anastomosed consistently with the superficial orbital arcade at a predictable site. All 7 flaps survived completely.

CONCLUSION

A new distally based perforator flap from the zygomaticotemporal region is described regarding its anatomical basis and clinical applications to eyelid reconstruction. With a vascular axis consistently present and a pivot adjacent to the defects, the flap is more reliable in vascularization, and less harm to its donor site than orbicularis oculi myocutaneous flaps, and poses no concern about whether the zygomatico-orbital artery is present or not.

Single-staged Tunneled Forehead Flap for Medial Canthal and Eyelid Reconstruction

Purpose:

The paramedian forehead flap, while initially used for reconstruction of nasal defects, has been adapted for repair of anatomical subunits in the medial canthal and eyelid area. A significant obstacle for utilizing the flap has been the bulky, unsightly vascular pedicle that is maintained between surgical stages. We describe our surgical experience using the tunneled variation in a single stage procedure.

Methods:

A retrospective chart review was performed of three surgeons’ charts over a 5-year period. All patients who underwent the tunneled paramedian forehead flap variation were selected. Outcomes measured included underlying pathology, Mohs defect area and depth, and canalicular involvement.

Results:

A total of 20 tunneled flaps were performed after successful Mohs excision of cutaneous malignancies. The average Mohs defect surface area was 13.57 cm² with depth down to periosteum (n = 13), bone (n = 5), or orbital fat (n = 2). Five patients had full-thickness eyelid defects (25%), and nine (45%) had canalicular defects. The overall complication rate for this study was low with no flap failure. Two patients (10%) desired thinning of the subcutaneous flap for improved cosmesis, and one patient (5%) required further eyelid revision due to the complexity of the initial Mohs defect. The remaining 17 patients required no further surgical procedures.

Conclusion:

The tunneled paramedian forehead flap is a useful technique for medial canthal and eyelid reconstruction. This technique allows reconstruction of a challenging area. Complication rates are low, and this tunneled variation provides a single stage variation to the traditional multistage forehead pedicle flap.

Subcutaneous pedicled propeller flap for reconstructing the large eyelid defect due to excision of malignancies or trauma

Large eyelid defect after excision of malignancies or trauma is difficult to reconstruct due to special structure and function of the eyelid. In this study, we aimed to present the outcomes of subcutaneous pedicled propeller flap for reconstructing the large eyelid defect after excision of malignancies or trauma. A retrospective review of patients diagnosed with eyelid defect due to excision of malignancies or trauma, and undergoing subcutaneous pedicled propeller flap for reconstructing the large eyelid defect, was conducted at our hospital. The clinical data were collected and analyzed. A total of 15 patients were included in the cases series. Nine patients were diagnosed with basal cell carcinoma, 3 patients with epidermoid carcinoma, and 3 patients with trauma. All the defects were successfully covered with this designed flap. There was no flap necrosis in all the cases. No functional problems were observed in all of the cases. At long-term postoperative follow-up, the average score of patients’ satisfaction was good. This subcutaneous pedicled propeller flap is a feasible alternative technique for reconstructing the large eyelid defect after excision of malignancies or trauma. This flap option could avoid the use of free flaps for large defect.

Challenging eyelid reconstruction in malignancies: Case reports

Eye is one of the most crucial organs in need of protection. The most important function of eyelids is designed to protect the eyeball. Despite their small and thin surface area, they are among the most sunlight-exposed area of skins, hence, it is prone to develop eyelid tumors. As the malignant tumors have the tendency of growing aggressively and have a high mortality, we have to meticulously remove the lesion along with its surrounding tissue, if needed, to ensure the clearance of tumor margin. To strike a suitable outcome between the cosmetic and function after tumor removal is a quite challenging task. Compromise on aesthetics and eyelids' indispensable function of protecting the eyes during management, may lead to unfavorable cosmetic deformity and loss of vision. Therefore, it is imperative that wise selection of appropriate techniques be discussed and managed accordingly. In this article, the authors reported two case scenarios of eyelid reconstruction which was performed to show the management of full-thickness defect after removal of the malignant neoplasms. Skin flaps and graft technique used to reconstruct the eyelid in each patient was different to emphasize that eyelid malignancies require an individualized management.

Reconstruction of Extensive Periorbital Defects With Pericranial Flap

ABSTRACT

Wide excision of recurrent malignant tumors of periorbital region leaves deep and large composite defects, requiring a reconstruction to restore both the form and function of the eyelids. In this study, a pericranial flap was utilized in the reconstruction of large, complex defects of periorbital region.This study included 5 patients who underwent wide excision of recurrent large medial canthus and supraorbital rim malignant tumors. All defects involved the medial parts of eyelids including medial canthal ligaments, nasal walls, periosteum, and medial orbital walls. Defects were reconstructed via a pericranial flap, which was facilitated by the natural concavity and the acute angled nature of the medial canthus.The pericranial flap is not only a versatile alternative to the local or regional flaps in the reconstruction of periorbital defects, but also has the advantages of availability of abundant amount of flap tissue.

Ideal esthetic and functional full-thickness lower eyelid "like with like" reconstruction using a combined Hughes flap and swing skin flap technique

BACKGROUND

A goal in ideal lower eyelid reconstruction is to achieve not only an esthetic recovery of the shape of the eyelid but also to obtain satisfactory eyelid function without damage to the corneal surface. In this report, we introduce our "Like with Like" reconstruction technique using a combined Hughes flap and swing skin flap. The Hughes flap is a tarsoconjunctival pedicled flap from the upper eyelid, and the swing skin flap is a kind of transposition flap based on the orbicularis muscle pedicle.

PATIENTS AND METHODS

Eight patients who had more than 25% of the lower eyelid affected by a full-thickness defect were included. There were five men and three women, and the average age was 68.4years old. All patients had undergone wide tumor excision of the lower eyelid due to a malignant tumor and had also had primary two-stage eyelid reconstruction with a combined Hughes flap and swing skin flap.

RESULTS

The average reconstructive time was 1:20, and no postoperative severe complications such as flap necrosis or wound dehiscence were observed. The follow-up period was an average of one year, and there were no functional problems such as ectropion, lower eyelid retraction, lid margin hypertrophy, lacrimation disorder, or corneal problems observed in any cases. Esthetically, no reconstructed eyelid bulging or asymmetry in the lid margin was observed in any of the cases.

CONCLUSIONS

Combining the Hughes flap and skin swing flap technique might be the best choice for a full-thickness lower eyelid defect with regard to the esthetic and functional results.

The Effect of Canthotomy on Blood Perfusion During the Repair of Lower Eyelid Defects

PURPOSE

Canthotomy is frequently used to mobilize extra tissue when repairing larger lower eyelid defects. The aim of this study was to explore the effect of canthotomy on blood perfusion and oxygen tension.

METHODS

Eight pigs underwent a wedge resection of the lower eyelid and canthotomy (with cantholysis involving the lateral palpebral artery). The wedge resection was performed 8, 6, and 4 mm from the canthotomy. Perfusion and oxygen tension were monitored in the eyelid between the wedge resection and canthotomy using laser Doppler velocimetry and a Clark electrode. Verapamil was administered, and measurements were also performed 12 hours after surgery, to investigate the possible effects of vasospasm RESULTS:: The wedge resection alone did not affect perfusion. Canthotomy led to a reduction in perfusion; being 60% when the length of remaining eyelid was 8 mm, 32% when it was 6 mm, and 24% when it was 4 mm. Similar results were observed for oxygen tension. Vasospasm did not affect the results.

CONCLUSIONS

Canthotomy in combination with a wedge resection of the lower eyelid affects blood perfusion. A smaller length of remaining eyelid tissue will have less perfusion. This may not have any implications in cases of direct closure, but may play a role when the eyelid is to provide oxygen and nutrients to avascular grafts.

Auricular cartilage versus donor sclera as a wrapping of hydroxyapatite orbital implants

AIM

To retrospectively compare postoperative outcomes after primary enucleation and placement of a hydroxyapatite (HA) implant without wrapping, wrapped with auricular cartilage or donor sclera.

METHODS

Medical records of patients presented as intraocular tumor or severe ocular injury were identified from the electronic medical record system. Cases underwent enucleation and HA orbital implantation were enrolled in this study and were divided into 3 groups according to the wrapping material of HA implant. Cases with autogenous cartilage caps were enrolled in group A (n=11), with donor sclera caps in group B (n=12), and without any wrapping material in group C (n=9). Follow-ups were set at 1, 2wk, 1, 3, 6, and 12mo after surgery.

RESULTS

Altogether 32 cases finished the follow-up and were enrolled in this study. Three cases (27.27%) in group A, 4 cases (33.33%) in group B, and 4 cases (44.44%) in group C developed one complication each after surgery. In group A, no HA exposure occurred, but conjunctival inclusion cyst occurred in one and severe conjunctive chemosis in two cases. In group B, one HA exposure occurred, conjunctive inclusion cysts occurred in one, severe conjunctive chemosis occurred in one, and conjunctival granuloma occurred in one case. In group C, one HA exposure occurred, severe conjunctive chemosis occurred in two cases, and conjunctival granuloma occurred in one case. The case of exposure of none-wrapped implant was noted in the first 6mo after placement of the orbital implant. The case of exposure of donor sclera-wrapped implant was noted at the 12mo after placement of the orbital implant. Both exposure cases were treated successfully with conservative treatment.

CONCLUSION

With low incidence of implant exposure and mild complications, auricular cartilage can be a good choice of alternative wrapping material of orbit implant with satisfied outcome.

The Use of Fascia Lata Free Graft for Lateral Canthus Reconstruction Following Mohs Lower Lid Surgery

We present a case of a 75-year-old patient who underwent reconstruction of the lower eyelid and lateral canthus following removal of 80% of the lower eyelid due to basal cell carcinoma. A Hughes transconjunctival eyelid-sharing flap was used to form the posterior lamella, and a free skin graft from the ipsilateral upper lid was used to recreate the anterior lamella. The lateral canthal ligament was reconstructed using a free fascia lata graft. A periosteal flap was not used due to local scarring that was the result of previous multiple lateral canthal surgeries. Skin preservation in the lateral canthal area and additional horizontal support for the lower eyelid were achieved by using a local advancement flap. This two-stage surgery produced excellent functional and cosmetic effects. Fascia lata free graft can be an alternative to the periosteal flap for reconstruction of the lateral canthal ligament when use of the lateral orbital periosteum is not feasible.

Total and near-total lower eyelid reconstruction with prefabricated orbicularis oculi musculocutaneous island flap

Full thickness lower lid defects are frequently encountered during daily practice. The unique anatomy of the eyelids hinders reconstructive efforts. The aim of the study is to develop an effective and easy procedure for the reconstruction of full thickness defects of the lower eyelid. Here we present six cases, which we treated with an orbicularis oculi musculocutaneous island flap prefabricated with a chondrocutaneous graft. Five of the six cases suffered from tumors, while one had congenital coloboma of the lower lid. A chondrocutaneous graft harvested from the ear was placed under the orbicularis oculi musculocutaneous flap. Three weeks later, the defect was created and the prefabricated flap was transposed to the defect. Two cases had superficial distal skin loss and one had prolonged oedema. No major complication or tumor recurrence was seen. Using this method, the principle "replace with like" is fulfilled. Orbicularis oculi musculocutaneous island flap prefabricated with postauricular chondrocutaneous composite graft seems to be a feasible method for the reconstruction of full thickness defects of the lower eyelid with its low donor morbidity and good outcomes.

Multidisciplinary Treatment to Restore Vision in Ocular Burns

Periorbital burns generate contraction and distortion of periorbital soft tissue, causing eyelid malfunction, further contributing to loss of vision from corneal scarring or perforation. We present our multidisciplinary algorithm to restore vision in patients with burn-related bilateral corneal blindness with light perception. Chart review was performed for four consecutive burn patients requiring periocular reconstruction and keratoprosthesis. Initial treatment included globe coverage with eyelid releases and grafts. Strategy of corneal replacement was determined by eyelid position and function and sufficiency of tear production. All patients were corneal blind with light perception only and cicatricial ectropion. The eye with better visual prognosis was reconstructed. Eyelid reconstruction procedures consisted of lid releases with full-thickness skin graft (FTSG) or split-thickness skin graft (STSG). Two patients regained adequate lid function and underwent standard keratoprosthesis placement. Two underwent mucous membrane grafts followed by keratoprosthesis. All patients experienced improved postoperative vision in their reconstructed eye. Corneal injury due to periocular burns can lead to blindness. Early involvement of ophthalmology, protective measures, and early ectropion release are critical. For severe burns, a multidisciplinary approach, where adequate globe protection is followed by keratoprosthesis placement, can effectively restore vision in patients with burn-related corneal blindness.

Analysis of Risk Factors Associated With Drooping Deformity After Lower Eyelid Reconstruction: A Newly Developed Drooping Index

BACKGROUND

Lower eyelid reconstruction is challenging because of the risk of severe postreconstruction deformities of the lower eyelid, such as drooping, entropion, and ectropion. However, the risk factors for these postreconstruction deformities are unclear. The present study aimed to quantify the drooping deformity of the lower eyelid after reconstruction using a cheek rotation flap and to identify risk factors associated with postreconstruction deformities.

METHODS

Our study group included 28 patients who underwent full-thickness lower eyelid reconstruction using a cheek rotation flap for anterior lamella reconstruction. We developed the drooping index to classify postreconstruction outcomes as good (index <1.2), fair (index between 1.2 and 1.5), and poor (index >1.5). We identified risk factors for a drooping deformity using univariate analyses (Mann-Whitney U or Spearman rank correlation, depending on data distribution).

RESULTS

Overall, the drooping index ranged between 1.0 and 2.11, with an average value of 1.3. A good outcome was obtained in 11, a fair outcome in 12, and a poor outcome in 5 patients. Clinically severe ectropion was observed in five of the 17 patients in the fair and poor outcome groups, with four of these patients requiring revision surgery. Risk factors for postreconstruction drooping deformity included medial location of the tumor, resection involving more than 50% of the horizontal width of the lower eyelid, and dissection of subcutaneous tissue of the cheek extending below the zygomatic arch.

CONCLUSIONS

A cheek rotation flap provides satisfactory outcomes for full-thickness reconstruction of the lower eyelid. Extension of dissection of subcutaneous tissue of the cheek below the zygomatic arch increases the risk of postsurgical drooping deformity. Our drooping index provides a quantitative measure of drooping deformity and is clinically useful to classify outcomes.

Laterally Based Orbicularis Oculi Myocutaneous Flap: Revisiting for the Secondary Ectropion Correction

BACKGROUND

The management of lower eyelid ectropion is considered a challenge. Lower eyelid ectropion is conventionally reconstructed with a full-thickness skin graft or a local flap. However, complications as scar contracture and the recurrence of ectropion frequently occur. This article describes an effective surgical technique for ectropion correction using an upper eyelid as the laterally based orbicularis oculi myocutaneous flap.

METHODS

The flap was used in 7 patients who were subjected to lower eyelid reconstruction. A strip of unipedicled orbicularis oculi myocutaneous flap from the lateral canthus was elevated and transposed to the lower eyelid to suspend the lower eyelid and repair the skin defect.

RESULTS

Satisfactory eyelid function and cosmetic appearance were obtained and no recurrence was found in 2-years follow-up. The method proved that the donor scar was well hidden in the supratarsal crease. Mild flap color change occurred in the early stages but disappeared gradually within 2 months after.

CONCLUSIONS

The use of this flap not only gives similar tissue reconstruction, additional support, well-hidden scar, and no loss of function, but also fast flap rising with the reliable donor. With a thorough knowledge of anatomy, the authors believe that their technique described below will expand anatomical understanding and powerful reasons for using laterally based orbicularis oculi myocutaneous flap for not only reconstructive but also aesthetic surgeons.

Postoncological lacrimal duct reconstruction: A practical classification system for reconstructive planning and short-term results of a case series

BACKGROUND

Surgical resection of skin tumors in the medial canthal area may damage the lacrimal duct and can result in chronic epiphora. Postoncologic reconstruction of the lacrimal duct has not been studied extensively. The current study discusses the anatomical and functional features of the lacrimal duct. It describes short-term functional outcomes after monocanalicular reconstruction of the lacrimal duct in a case series of 10 patients.

METHODS

From February 2015 to October 2017, all patients with a postoncological lacrimal duct defect were analyzed to make an anatomical classification. The functional outcomes of patients after monocanalicular reconstruction were measured with the Munk scale up to 3 months after stent removal.

RESULTS

Twelve patients had lacrimal duct defects after Mohs resection. Anatomical characteristics were used to create a clinical classification for lacrimal duct defects. This classification divides the upper (U) and lower (L) proximal lacrimal duct into two sections which can be damaged: the punctum and pars verticalis (1), the canaliculus horizontalis (2), or combined (3). The Common lacrimal duct (C) is the distal part of the lacrimal duct and can also be affected. Ten patients were analyzed after lacrimal duct reconstruction. Three months after stent removal, none of the patients suffered from epiphora.

CONCLUSIONS

This article proposes an anatomical classification for lacrimal duct defects in the proximal lacrimal drainage system. The classification can be applied in comparing cases and determining reconstructive strategies after oncologic skin tumor resection. Short-term results are promising for future efforts to reconstruct the lacrimal duct.

Polarization and Distribution of Tumor-Associated Macrophages and COX-2 Expression in Basal Cell Carcinoma of the Ocular Adnexae

PURPOSE

Basal cell carcinoma (BCC) is a locally invasive skin tumor which can be subdivided into a circumscribed nodular and an invasive fibrosing subtype. There is increasing evidence that macrophages play an important role in interacting between tumor cells and their microenvironment, thereby affecting not only the invasive potential but also the patients' prognosis. Thus, we wanted to compare these two BCC variants with regard to tumor-related inflammation, COX-2 expression, distribution, and polarization of tumor-associated macrophages.

MATERIAL AND METHODS

30 BCCs (nodular: n = 15; fibrosing: n = 15) of the ocular adnexae were investigated by histopathology and immunohistochemistry. The grade of inflammation was evaluated on hematoxylin and eosin stains (score: 0-3). Immunohistochemical stains for CD68 (macrophages), Ki67 (proliferative activity), and COX-2 as well as immunofluorescence stains for CD68 and CD163 (to distinguish M1 and M2 macrophage subtypes) were performed. SPSS was used for statistical analysis.

RESULTS

Fibrosing BCCs were predominantly located on the lower lid, while nodular BCCs showed a broader distribution (p = 0.013). The fibrosing BCC subtype was associated with a higher degree of inflammation (p < 0.001) and revealed a higher COX-2 immunoreactivity than nodular BCC (p = 0.012). COX-2-positive cells were predominantly located on the infiltrating edge of the tumor. Macrophage polarization was balanced regarding M1 and M2 macrophage subtypes. There was no difference in macrophage number (p = 0.389) or polarization (p = 0.161) between nodular and fibrosing BCC.

CONCLUSIONS

The findings indicate that COX-2 represents a factor for invasion of BCC. Macrophage polarization did not play a major role for aggressive behavior. However, other inflammatory components than tumor-associated macrophages seem to be involved in tissue destruction and thereby an invading growth pattern since fibrosing BCC revealed a significantly more intense inflammatory reaction in the surrounding tissue.

Posterior Lamellar Reconstruction of the Lower Eyelid With a Gingivoalveolar Mucosal Graft

The anterior and posterior lamellae should be simultaneously reconstructed to repair the upper and lower eyelid's full thickness defects after resection of a malignant tumor. The author described a gingivoalveolar mucosal graft for posterior lamellar reconstruction of the lower eyelid. Between November 2014 and September 2017, 11 patients (6 women, 5 men; mean age 62.7 years) with 13 posterior lamellar defect of lower eyelid underwent reconstruction with gingivoalveolar mucosal graft. The defects ranged from 10 x 8 mm to 20 x 10 mm. For 11 lower eyelid defects, the anterior lamellar defect was previously reconstructed with an appropriate local flap. The remaining 2 defects were repaired with graft only. The mean follow-up period was 15.3 months. The pathologic diagnoses were squamous cell carcinoma for 8 lower eyelid lesions and basal cell carcinoma for the remaining 5 lower eyelid lesions. No case of necrosis and infection was observed in any flap or graft. Also, there was not observed ectropion or lid laxity at lower eyelids. However, redness developed in 1 eye, but healed in 1 week. Donor areas completely improved with secondary healing with no any complication. Gingivoalveolar mucosal graft is a reliable and easy accessible choice for posterior lamellar reconstruction of eyelid defects. While the gingival mucosal part provides a stable and tight structural support for marginal palpebral area, the alveolar part occupies the conjunctival side without causing corneal irritation.

Surgical Management of Large Periorbital Cutaneous Defects: Aesthetic Considerations and Technique Refinements

PURPOSE

The aim of this study was to repair large periorbital cutaneous defects by an innovative technique called PEPSI (periorbital elevation and positioning with secret incisions) technique with functional and aesthetic outcomes.

METHODS

In this retrospective study, unilateral periorbital cutaneous defects in 15 patients were repaired by the PEPSI technique. The ages of patients ranged from 3 to 46 years (average, 19 years). The outcome evaluations included scars (Vancouver Scar Scale and visual analog scale score), function and aesthetic appearance of eyelids, and patient satisfaction. The repair size was measured by the maximum advancement distance of skin flap during operation.

RESULTS

All patients achieved an effective repair with a mean follow-up of 18.3 months. Except one with a small (approximately 0.3 cm) necrosis, all patients healed with no complication. The mean Vancouver Scar Scale and visual analog scale scores were 2.1 ± 1.7 and 8.5 ± 1.2, respectively. Ideal cosmetic and functional outcomes were achieved in 14 patients (93.3%). All patients achieved complete satisfaction except 1 patient with partial satisfaction. The mean maximum advancement distance of skin flap was 20.2 mm (range, 8-50 mm).

CONCLUSIONS

This study demonstrated that the PEPSI technique is an effective method to repair large periorbital cutaneous defects with acceptable functional and aesthetic outcomes.

Eyelid Reconstruction

LEARNING OBJECTIVES

After reading this article, the participant should be able to: 1. Describe eyelid anatomy and demonstrate full understanding of the critical structures and basic principles of eyelid reconstruction. 2. Evaluate individual defects, analyze the missing components, and formulate a reconstructive algorithm. 3. Anticipate potential complications and design effective strategies to manage and treat common complications following eyelid reconstruction.

SUMMARY

Defects of the eyelid can result from trauma, burns, or resection of cutaneous malignancies. Repair of eyelid defects presents unique challenges to reconstructive surgeons. A fundamental understanding of eyelid anatomy and familiarity with the myriad of options for reconstruction are critical for achieving optimal outcomes. Under ideal circumstances, the aims of reconstruction should be to restore form and function and to replace "like with like."

Defining the Role of Secondary Intention Healing in Full-Thickness Lid Margin Defects

More than 30 years have passed since the first case series was published regarding the phenomenon of secondary intention healing in relation to lid margin defects. Despite the fascinating results, the technique has not gained widespread support. This study looks at a series of 34 marginal lower lid defects allowed to heal without intervention. The results are remarkable for their consistently high quality, in terms of both cosmetic and functional outcomes. Medial lid defects, in particular, yielded results that would be difficult to surpass by conventional reconstructive techniques. The evidence presented here shows that secondary intention healing in lid margin defects should be considered as a genuine alternative to formal reconstruction, challenging the established dogma of bilamellar repair. For certain lid defects it is quite possibly (and unexpectedly) the new treatment of choice.

Application of Kuhnt-Szymanowski Procedure to Lower Eyelid Margin Defect after Tumor Resection

Background:

Lower eyelid reconstruction after tumor removal is always challenging, and full-thickness defects beyond half of the eyelid length require a flap from a part other than the remaining lower eyelid, such as the temporal area or the cheek.

Objective:

We aimed to report our experience of applying Smith-modified Kuhnt–Szymanowski, one of the most popular procedures for paralytic ectropion, for reconstructing oblong full-thickness lower eyelid margin defect.

Materials and Methods:

We performed Smith-modified Kuhnt–Szymanowski on 5 cases of oblong full-thickness lower eyelid margin defect after skin cancer removal. The mean age of patients was 80.0 years. The horizontal widths of the defects ranged from half to two-thirds of the lower eyelid length and the vertical width ranged from 5 to 9 mm.

Results:

We obtained good functional and esthetic results in all cases. No patients developed ectropion or lower eyelid distortion, and all patients were satisfied with their results.

Conclusions:

We utilized the procedure for morphological revision as a reconstructive procedure for eyelid margin defect by considering the defect as a morphological deformity of the eyelid margin; thus, donor tissue was not required to fill the defect and we could accomplish the reconstruction simply, firmly, and less invasively.

Repairs of Large Defects of the Lower Lid and the Infraorbital Region With Suspended Cheek Flaps With a Dermofat Flap

After the repair of large defects of the lower lid and the infraorbital region using larger flaps without adequate support, retractions of the lower lid may be observed due to the weight of the flap. In this study, the authors' aim is to present the outcome of the repairs they performed on large defect areas in the lower lid and the infraorbital region using cheek flaps suspended by a dermofat flap.The method was performed on 7 patients between 2011 and 2015. Among the patients, 4 were female, while 3 were male. The mean age of the patients was 61.3 (54-69) years. In all the patients, the defects were secondary to tumor excisions. The mean size of the defects was 4.4 × 5 cm (4 × 4 cm to 6 × 5 cm). In all the patients, the repair of the defect was performed using the Mustarde flaps prepared in the subcutaneous plane. After the flap was advanced to the defect area, a dermofat flap was prepared from the part at the lateral canthal area and was sutured to the periosteum superiorly to the lateral canthus.Patient satisfaction and functionality was high during the long-term follow-up. While minimal scleral show occurred in 1 patient, the lid position was normal in the other patients.The authors are of the opinion that the method they used may reduce the risk of lid deformities that may develop with the cheek flaps used to repair large lid defects.

Total Upper Eyelid Reconstruction with Modified Cutler-Beard Procedure Using Autogenous Auricular Cartilage

INTRODUCTION

Malignant tumour in upper lid is a surgical challenge to oculoplastic surgeon. Full thickness defect created after removal of large tumour promptly treated with modified cutler beard procedure using autogenous auricular cartilage. Surgical procedure is two staged: In first stage, removal of the tumour followed by full thickness flap repaired; In second stage, opening the closed lid with lid margin repair. Post-operatively, there is good anatomical, functional and cosmetic restoration of the eyelid similar to the other eye.

AIM

To evaluate the efficacy of the modified Cutler-Beard procedure using autogenous ear cartilage for tarsal plate reconstruction in the repair of 70-100% upper eyelid defects.

MATERIALS AND METHODS

This is a prospective, interventional case series of 16 patients over a period of three years. Patients with upper eyelid defects, secondary to removal of tumour, greater than or equal to 70% were included. Of these patients, those with lymph node involvement, distant metastasis, lower eyelid involvement, corneal infiltration or intra-orbital extension were excluded. FNAC was done in all the cases. Created defect was measured in mm (length and width) and later expressed in percentage. Pre and Post-operative measurement of Levator Palpebrae Superioris (LPS) was done. Pre and Post-operative measurement of Margin to Reflex Distance (MRD1) were also noted.

RESULTS

Upper eyelid recreation was successful in all patients without complications. Pre-operative LPS action ranged from 0-4 mm, while post-operative LPS action was 12-14 mm. Pre-operative MRD1 ranged from -4 millimeters to -1 mm, while post-operative MRD1 was +3 to +4 millimeters. The follow-up period ranged from six months to two years. Every patient had a successful upper eyelid reconstruction.

CONCLUSION

The modified Cutler-Beard procedure using an autogenous auricular cartilage graft is an effective procedure for repair of large upper eyelid defects, with acceptable functional and cosmetic results. Furthermore, it is particularly useful in resource-poor areas, due to lower cost than other available options.

Total Upper and Lower Eyelid Reconstruction: A Rare Procedure--A Report of Two Cases

Reconstruction after total amputation of the upper and lower eyelids with preserved globe is rare. The primary goal is immediate corneal protection. The second goal is to restore mobility, occlusion, and facial symmetry. Two women had full-thickness excision of both upper and lower eyelids to treat a melanoma. The reconstruction method required four steps over a period of 5 months. A buccal mucosal graft was used to recreate the conjunctival lining, and an oblique forehead flap was used to recreate the skin. Resection of the flap and replacement by a full-thickness skin graft made it possible to recreate a thin and mobile upper eyelid. Visual acuity remained unchanged, and the eyelids remained functional despite a degree of ptosis and lower eyelid retraction.

Tessier No. 3 and No. 4 clefts: Sequential treatment in infancy by pre-surgical orthopedic skeletal contraction, comprehensive reconstruction, and novel surgical lengthening of the ala base-canthal distance

BACKGROUND

Repair of facial clefts implies wide tissue mobilization with multi-stage surgical treatment. Authors propose pre-surgical orthopedic correction for naso-oro-ocular clefts and a novel surgical option for Tessier No. 3 cleft.

METHODS

Two male infants, a Tessier No. 3 cleft (age 7 months) and another Tessier No. 4 (age 3 months), were treated with a modified orthopedic Latham device with additional septo-premaxillary molding and observed to age four years. Tessier No. 3 orthopedic measurements were obtained by image corrected cephalometric analysis. Subsequent repair included tissue expansion on Tessier No. 4 and naso-frontal Rieger flap combined with myocutaneous upper lid flap on Tessier No. 3.

RESULTS

Orthopedic movements ranged from 18.5 mm in bi-planar to 33 mm in oblique analyses. Tissue margins became aligned with platform normalization. Tissue expansion on Tessier No. 4 improved distances from ala base-lower lid and subalar base-lip. The naso-frontal flap combined with myocutaneous upper lid flap on Tessier No. 3 had similar achievement, but also sufficiently lengthened ala base-canthal distance.

CONCLUSIONS

Repairs were facilitated by pre-surgical orthopedic correction. The naso-frontal flap combined with an upper lid myocutaneous flap seems viable as a single-stage option to lengthen ala base-canthal distance to advance repair achievement in unilateral Tessier No. 3.

Congenital upper eyelid coloboma: embryologic, nomenclatorial, nosologic, etiologic, pathogenetic, epidemiologic, clinical, and management perspectives

Purpose:

To review the recent literature and describe the authors’ experience with congenital upper eyelid coloboma.

Methods:

In this review, we will summarize the embryologic and etiopathogenetic bases of congenital upper eyelid coloboma, and study the published clinical reports. We will also attempt to briefly shed some light on the rarer syndromic curiosities associated with upper eyelid coloboma.

Results:

Congenital upper eyelid colobomas are one of the few nontraumatic oculoplastic emergencies that may occasionally present in the first few days of life with a corneal ulcer and may even present with impending perforation. They can present with or without corneopalpebral adhesions, may be isolated findings or a part of a larger spectrum of congenital anomalies as in the case of Fraser syndrome or Goldenhar syndrome, or could be associated with other rare curiosities that could challenge the clinician with a huge diagnostic dilemma.

Conclusions:

Existing literature dealing with congenital colobomas of the upper eyelid is fraught with nosologic problems, confusing etiologies, and overlapping clinical features. We attempted to clarify the salient clinical features, outline the management principles, and until a time in the not-so-distant future where advances in molecular genetic testing would help redefine the etiology and the diverse clinical spectrum of genetic diseases associated with upper eyelid colobomas, we propose a simplified classification scheme based on the relation of the coloboma to the cornea, the presence or absence of systemic features, and all the syndromic and nonsyndromic associations of congenital coloboma of the upper eyelid known today.

In this review, the authors will describe the pathogenesis of upper eyelid coloboma, suggest a new simplified classification system, describe the clinical picture in detail, clarify the various syndromic associations of upper eyelid coloboma, and lay out the basic surgical principles of management.

Venous Graft for Full-thickness Palpebral Reconstruction

Full-thickness palpebral reconstruction is a challenge for most surgeons. The complex structures composing the eyelid must be reconstructed with care both for functional and cosmetic reasons. It is possible to find in literature different methods to reconstruct either the anterior or posterior lamella, based on graft or flaps. Most patients involved in this kind of surgery are elderly. It is important to use easy and fast procedures to minimize the length of the operation and its complications. In our department, we used to reconstruct the anterior lamella by means of a Tenzel or a Mustardé flap, whereas for the posterior lamella, we previously utilized a chondromucosal graft, harvested from nasal septum. Thus, these procedures required general anesthesia and long operatory time. We started using a vein graft for the posterior lamella. In this article, we present a series of 9 patients who underwent complex palpebral reconstruction for oncological reasons. In 5 patients (group A), we reconstructed the tarsoconjunctival layer by a chondromucosal graft, whereas in 4 patients (group B), we used a propulsive vein graft. The follow-up was from 10 to 20 months. The patient satisfaction was high, and we had no relapse in the series. In group A, we had more complications, including ectropion and septal perforations, whereas in group B, the operation was faster and we noted minor complications. In conclusion, the use of a propulsive vein to reconstruct the tarsoconjunctival layer was a reliable, safe, and fast procedure that can be considered in complex palpebral reconstructions.

[Hughes' operation and combined procedures]

BACKGROUND

The Hughes procedure is a standard and widely used technique for lower eyelid reconstruction. This paper presents the results of 55 patients who underwent reconstruction of the anterior and posterior lamella with the Hughes procedure at the University eye clinic in Salzburg between 2002 and 2012.

PATIENTS AND METHODS

This study included 55 patients who underwent lower eyelid reconstruction performed with the Hughes procedure including a full skin graft. In 95 % of patients (52/55) this method was performed after tumor resection. The defect size of the lower lid was at least 10 mm horizontally and ranged between 10 and 15 mm. Of the patients three were treated with a combined Hughes and Tenzel procedure whereas in five cases the Hughes procedure was combined with an autologous tarsoconjunctival flap of the contralateral upper lid and a local full skin rotational flap.

RESULTS

In 42 out of 55 patients both the eyelid function as well as the restoration of good cosmesis could be achieved. In 6 out of the remaining 13 patients suffering from minor complications, the function and cosmesis were restored after secondary minor surgery or additional conservative treatment. For six patients, further reconstructive surgery was necessary and one experienced a major complication in the form of a recurrence of basal cell carcinoma necessitating exenteration.

CONCLUSIONS

The Hughes procedure is a well-suited technique for eyelid reconstruction of shallow defects extending beyond 10 mm horizontally and involving up to 100 % of the eyelid. The latter require a combined procedure such as the Hughes procedure and an autologous tarsoconjunctival flap and skin graft.

Eyelid reconstruction following excision of cutaneous malignancy

PURPOSE

With advancing age, cutaneous malignancy around the eye becomes more prevalent. Different kinds of malignant tumors of the eyelid have features particular to their subtype, and a diagnosis should be obtained before definitive treatment if possible. The aim of treatment is total tumor eradication with the smallest recurrence risk, using the most cost-effective method that is acceptable to the patient. Reconstruction of periocular defects following excision of eyelid malignancy can present difficulties, and various reconstructive procedures can be applied.

METHODS

The retrospective study carried out has analyzed 173 patients submitted to surgery for skin cancers located in the eyelid region with particular reference to the period January 2005 to January 2012. We analyzed certain data (age, sex, histological types, affected portion of eyelid, incidence recurrence by histological type, incidence recurrent tumors previously treated by surgery [secondary], type of removal, type of reconstruction, and mean time elapsed between the demolitive act and disease recurrence) both individually and in correlation with each other. Multivariate analysis (Cox algorithm) was used to identify those variables that had a clear statistical significance.

RESULTS

Melanoma and lentigo maligna have the highest tendency to relapse (33%), but squamous cell carcinoma has more rapid replicative capacity.

CONCLUSIONS

Extensive demolition should always be followed by extensive reconstruction. Even through intervention with an extensive demolition in cases of large tumors in the eyelid and cantus, it has not been possible to avoid the recurrence of the disease. The average time of recurrence when compared with reconstruction varies between 28 (minimum) and 39 months (maximum).

Defect closure in the paranasal region: an enduring challenge

BACKGROUND

The paranasal region constitutes a demanding issue for the reconstructive surgeon. Its complex anatomy, with concavity in close contact with convexity, and a high density of functional and aesthetically important facial components demands specific concern. Due to such complexity, numerous procedures for the reconstruction of paranasal defects have been published, including skin grafts and flaps in random pattern or axial style from the glabella, upper lid, nasal root, or cheek.

OBJECTIVES

In this review, we recall classical reconstructive procedures and compare them with innovative procedures that could possibly gain importance in the following years.

METHODS

We contrast the pros and cons concerning donor site morbidity, surgical elaborateness, and functional and aesthetic outcome, and substantiate our findings with photographic results from our own patient material.

RESULTS AND CONCLUSION

The reconstruction of paranasal defects remains a challenge; nevertheless, the growing toolbox of reconstructive instruments facilitates a perfect reconstructive result.

[Trauma of periorbital soft tissue. Reconstruction with regard to functional and aesthetic aspects]

Complex midfacial trauma requires interdisciplinary management. A wide range of reconstructive procedures are needed and if necessary secondary and even tertiary interventions should be performed at the appropriate time. We present the case of a 45-year-old man who was involved in a car accident and presented with severe injuries to the periorbital soft tissue. The focus was on the reconstruction of this sensitive region with regard to functional and aesthetic aspects. In view of the severity of the injuries the final clinical status is considered to be very important. Special issues and pitfalls in the reconstruction of trauma cases and potential management are discussed.

Anthropometry of the medial canthal ligament related to naso-orbitoethmoidal fractures

OBJECTIVE

Medial canthal ligament (MCL) and lacrimal system are often associated with naso-orbitoethmoidal fractures. The MCL anchors tarsal plate to medial orbit and has an important role in lacrimal pump system. The purpose of this study was to describe the anatomy of the MCL and present the anthropometric measurements on cadaveric specimens.

METHODS

Dissections were performed on 14 formalin-fixed cadavers. The length, thickness, width of the MCL, width of the nasal dorsum, and intercanthal distance were measured with a digital caliper. A surgical microscope and an digital photo camera were used in all dissections. Means, SDs, and paired-samples t test were computed.

RESULTS

The mean lengths of the right and left MCLs were measured as 8.01 (SD, 2.27) and 7.93 (SD, 2.43) mm. The mean thicknesses of the right and left MCLs were 1.63 (SD, 2.41) and 1.75 (SD, 2.44) mm. The mean widths of the right and left MCLs were 4.20 (SD, 0.75) and 4.17 (SD, 0.61) mm. The intercanthal distance was 31.7 (SD, 1.7) mm. The width of the nasal dorsum was measured as 14.37 (SD, 1.9) mm. Length and thickness differed on both sides. Asymmetric insertion of medial canthi was observed in 5 specimens.

CONCLUSIONS

Reconstruction of traumatic telecanthus requires reaproximation of medial canthi and the displaced nasoethmoid bony fragment with transnasal wiring or microplates. Identification and reconstruction of detached medial canthi could be accomplished successfully with anatomic familiarity of the region. The most developed and firmly adherent was the anterior limb of the MCL. Reattachment of that part seems to be adequate for repair of a detached canthus.

Angular vessels as a new vascular pedicle of an island nasal chondromucosal flap: Anatomical study and clinical application

Successful eyelid reconstructions have been reported when using an axial nasal chondromucosal flap based on the dorsal nasal artery. The present study aimed to present a detailed anatomical description of the blood supply of the lateral nasal region and the angular artery, in order to propose the angular vessels as a new vascular pedicle for the island nasal chondromucosal flap. A total of 11 cadavers (22 hemi-faces) were examined. Observations with regard to the origin, course and distribution patterns of the angular artery were recorded. Based on the anatomical study findings, the angular vessels were proposed as a vascular source for the island nasal chondromucosal flap. Observations with regard to the varying origins of the angular artery were categorized into four types. The course of the angular artery along the nasojugal fold was constant. The angular artery branched off into the upper two-thirds of the lateral nasal region and anastomosed with the other vascular branches on the nasal dorsum. Clinically, reconstruction of a full-thickness defect of the lower eyelid was successfully performed by using this composite flap based on the angular vessels and an adjacent orbicularis oculi myocutaneous flap. Satisfactory esthetic outcomes were obtained for the donor and recipient sites. The angular artery is a good vascular source for an island nasal chondromucosal flap. The flap may be created safely and successfully in clinic. Island nasal chondromucosal flaps and nasolabial groove skin flaps based on the angular vessels may be designed simultaneously for use on full-thickness defects of the eyelid.
