Eyelid Reconstruction

Surgical margins and outcomes for eyelid melanoma: a systematic review and meta-analysis

No randomized trials exist to inform the peripheral surgical margins or depth of wide excision for eyelid melanoma. We performed a meta-analysis examining surgical margins and Breslow depth for eyelid melanomas. A systematic review was performed in August 2022 using PubMed, Cochrane, and Medline databases (1/1/1990 to 8/1/2022). Inclusion criteria included studies reporting surgical treatment of primary cutaneous melanomas of the eyelid with reported surgical margins. Ten articles were included. The studies were examined by surgical margin size (group 1: ≤ 0.5 cm; group 2 > 0.5 cm and ≤ 1.5 cm) and Breslow depth (group 1: ≤ 1 mm; group 2: > 1 mm). The odds ratio (OR) for local recurrence was 2.55 [95% CI 0.36-18.12], p = 0.18; regional metastasis was 0.70 [95% CI 0.00-23671.71], p = 0.48; and distant metastasis was 2.47 [95% CI 0.00-1687.43], p = 0.66. When examining by Breslow depth, the OR for local recurrence was 0.53 [95% CI 0.14-1.94], p = 0.34; regional metastasis was 0.14 [0.00-176.12], p = 0.54; and the OR for distant metastasis was 0.24 [95% CI 0.01-8.73], p = 0.46. There was a trend toward higher likelihood of recurrence and metastasis in the ≤ 0.5 cm group. Similarly, there is a trend toward higher likelihood of recurrence and metastasis with Breslow depth > 1 mm. A surgical margin of at least 0.5 cm and achievement of negative margins via permanent sections or MMS are likely needed to prevent adverse outcomes. En face sectioning may be a superior method of histological processing for eyelid melanoma.

Polymers and Biomaterials for Posterior Lamella of the Eyelid and the Lacrimal System

The application of biopolymers in the reconstruction of the posterior lamella of the eyelid and the lacrimal system marks a significant fusion of biomaterial science with clinical advancements. This review assimilates research spanning 2015 to 2023 to provide a detailed examination of the role of biopolymers in reconstructing the posterior lamella of the eyelid and the lacrimal system. It covers the anatomy and pathophysiology of eyelid structures, the challenges of reconstruction, and the nuances of surgical intervention. This article progresses to evaluate the current gold standards, alternative options, and the desirable properties of biopolymers used in these intricate procedures. It underscores the advancements in the field, from decellularized grafts and acellular matrices to innovative natural and synthetic polymers, and explores their applications in lacrimal gland tissue engineering, including the promise of 3D bioprinting technologies. This review highlights the importance of multidisciplinary collaboration between material scientists and clinicians in enhancing surgical outcomes and patient quality of life, emphasizing that such cooperation is pivotal for translating benchtop research into bedside applications. This collaborative effort is vital for restoring aesthetics and functionality for patients afflicted with disfiguring eyelid diseases, ultimately aiming to bridge the gap between innovative materials and their clinical translation.

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.

Azithromycin-carrying and microtubule-orientated biomimetic poly (lactic-co-glycolic acid) scaffolds for eyelid reconstruction

Introduction

Tarsal plate repair is the major challenge of eyelid reconstruction for the oculoplastic surgeon. The ideal synthetic tarsal plate substitute should imitate the microstructure and mechanical strength of the natural eyelid. The aim of this work was to develop a novel bionic substitute for eyelid reconstruction.

Methods

Three types of poly(lactic-co-glycolic acid) (PLGA) scaffolds (random, oriented, and azithromycin-loaded oriented scaffolds) were prepared using an improved thermal-induced phase separation technique. The microstructure of the scaffolds was examined by scanning electron microscopy. In vitro cytotoxicity was assessed using scaffold extracts. Fibroblast and primary rat meibomian gland epithelial cells (rMGCs) were cultured within the scaffolds, and their behavior was observed using fluorescence staining. Three types of PLGA scaffolds were implanted into rabbit eyelid defect in vivo to evaluate their inductive tissue repair function.

Results

We successfully fabricated three types of PLGA scaffolds with varying pore architectures, and the axially aligned scaffold demonstrated interconnected and vertically parallel channels. In vitro cytotoxicity tests using scaffold extracts revealed no apparent cytotoxicity. Fluorescence staining showed that both Fibroblast and rMGCs could adhere well onto the pore walls, with fibroblast elongating along the axially aligned porous structure. At 8 weeks post-implantation, all scaffolds were well integrated by fibrovascular tissue. The axially aligned scaffold groups exhibited faster degradation compared to the random scaffold group, with smaller fragments surrounded by mature collagen fibers.

Conclusion

The study found that the axially aligned scaffolds could well support and guide cellular activities in vitro and in vivo. Moreover, the axially aligned scaffold group showed a faster degradation rate with a matched integration rate compared to the random scaffold group. The findings suggest that the oriented scaffold is a promising alternative for eyelid tarsal plate substitutes.

Myocutaneous sliding flap for reconstruction of divided eyelid nevus

OBJECTIVE

To evaluate the myocutaneous sliding flap for restructuring the eyelid of divided nevus, thus optimizing the aesthetic outcome.

DESIGN

A retrospective clinical study.

PARTICIPANTS

Clinical data from patients with a small or medium-sized divided nevus of the eyelids between January 2015 and December 2018 in the Shanghai Ninth People's Hospital were reviewed.

METHODS

The safety and efficacy of a surgical approach using a myocutaneous sliding flap were evaluated based on postoperative features and complications.

RESULTS

This study included 53 patients with an average age was 21.6 years (range, 2-68 years). The lesions involved the inner canthus in 5 patients (9.43%) and the lateral canthus in 14 patients (26.42%). Three (5.66%) patients had undergone primary surgery elsewhere. Overall, the eyelid margins were in good shape postoperatively at an average follow-up of 22.7 months, and there were no obvious eyelid deformities, lagophthalmos, or other unacceptable complications postoperatively. The nevi were benign intradermal (60.38%), junctional (16.98%), and compound types (22.64%) without malignant transformation, as confirmed by pathologic examination. No malignant transformation was observed until the end of the follow-up period.

CONCLUSION

A myocutaneous sliding flap can provide an appropriately size pedicle graft and achieve satisfactory cosmetic results for divided eyelid nevus.

Two Advancement Flaps for Eyelid Margin Reconstruction of Small and Medium Defects and a Novel Design to Reduce Ocular Injury

Purpose

The key point of eyelid margin reconstruction is to keep both the support function and aesthetic appearance. The eyelid's complex anatomical structures make eyelid margin reconstruction demanding. Eyelid margin defects are conventionally classified by their width relative to the eyelid width: small, medium, or large. In this study, we introduce a reconstruction method for small to medium defects.

Patients and Methods

We conducted a single-center case series of patients from the practice of a single experienced plastic surgeon at a tertiary center. We included consecutive outpatients from 2014 to 2021. The inclusion criteria were (1) eyelid margin mass and (2) willingness to receive eyelid margin reconstruction by the reported method. The exclusion criteria were (1) eyelid margin mass involving most or all of the tarsus and (2) less than one year of follow-up. Patients were followed up face to face or online. Patients' demographics, clinical characteristics and outcomes, and satisfaction were collected. The clinical outcomes were assessed and scored by two plastic surgeons.

Procedure

We reconstructed the anterior lamella with an advancement musculocutaneous flap and repaired the posterior lamella with a specially designed advancement tarsoconjunctival flap, of which a piece of tarsus was shaved and the corresponding remnant conjunctiva was bent forward to cover the tarsus edge to avoid ocular injury.

Results

We included 24 patients (25 lesions). Almost all patients had eyelash discontinuity. One patient presented slight notching of the lower eyelid margin. The other patients reported no complications or recurrence. The average outcome score was 1.23±0.69, indicating that our method was excellent. All patients were very satisfied with the surgery. The average follow-up time was 5.75 years.

Conclusion

We report a reconstruction method for small to medium eyelid margin defects and a novel design for preventing ocular injury, which is an especially good option for transverse defects.

Tear trough ligament reset as a new method for tear trough deformity and dark circles correction

Tear trough deformities and dark circles are important parts of periorbital aging. In this study, the tear trough ligament was reset to correct the tear trough deformity, and its effect on dark circles was analysed. The medical records of 60 patients who underwent eye bag plastic surgery between January 2021 and February 2022 were analysed (30 had traditional eye bag plastic surgery and 30 had the tear trough ligament reset). The tear trough deformity score and the dark circle score showed that the corrective effect on the tear trough deformity in the reset group was better than in the traditional surgery group at six-month follow up (mean (SD) tear trough rating scale (TTRS) score = 4.82 (0.95) vs 5.92 (1.00), p < 0.0001; L* value 55.27 (2.90) vs 47.51 (3.00), p < 0.0001). The satisfaction of patients in the reset group was significantly higher than it was in the traditional surgery group (25/30 vs 18/30, p = 0.045). Tear trough ligament reset is a safe and effective surgical method of periorbital rejuvenation, especially for beauty seekers with obvious tear trough deformities.

A Systematic Approach of the Intrauterine Morphogenesis of the Human Palpebral Apparatus

The human eyelid embodies a vast diversity of functions. Acting as a protective shield for the ocular apparatus and as a light regulator in the sight process, eyelids stand a fascinating - yet omitted - role in facial aesthetics, serving as a racial trait by which humankind succeeded to manifest heterogeneity as a species. These assumptions are precisely forecasted right from in-utero life through intricate processes of growth and cell differentiation. In the Department of Anatomy of "Carol Davila" University of Medicine and Pharmacy, we performed morphological assessments on 41 embryos and fetuses with gestational ages ranging from 6 to 29 weeks. This study aims to illustrate the morphogenesis of eyelids in human embryos and fetuses and highlight macroscopic features which could potentially have significant clinical implications in ophthalmic pathology.

Reconstruction of a total defect of the lower eyelid with a temporoparietal fascial flap: a case report

The reconstruction of total lower eyelid defects is challenging to plastic surgeons due to the complicated anatomical structure of the eyelid. In addition, in the setting of cancer excision, the resection is deep, which requires some volume augmentation. However, in some cases, free tissue transfer is not applicable. We report a case of using a temporoparietal fascia flap (TPFF) for reconstructing a total lower eyelid defect. A large erythematous mass in an 83-year-old woman was diagnosed as squamous cell carcinoma by biopsy. After wide excision, the defect size was about 8× 6 cm. The lower eyelid structures including the tarsus were removed. The TPFF including the superficial temporal artery was elevated and inset to the defect area. After the flap inset, a split-thickness skin graft with an acellular dermal matrix was performed on the fascial flap. There were no wound problems such as infection, dehiscence, or necrosis. After the patient’s discharge, partial skin graft loss and ectropion occurred. The complications resolved spontaneously during the postoperative period. We report a case of reconstructing a lower eyelid defect using a TPFF. A TPFF can be applied to patients with large defects for whom free tissue transfer surgery is not appropriate as in this case.

Association of sensitive eyes with sensitive skin: A worldwide study of 10,743 subjects

INTRODUCTION

Sensitive eyes are commonly reported by patients but there are very few epidemiological studies on this disorder. The aim of this study was the evaluation of the self-reported frequency of sensitive eyes and the association with sensitive skin.

METHODS

A survey was performed on a representative sample of the population aged more than 18 years in five different countries (Brazil, China, France, Russia, and the United States). All participants answered a questionnaire on sociodemographic characteristics; skin phototype; eye color; tobacco consumption; exposure to sunlight, air pollution or having pets; and sleep disorders. The presence of sensitive eyes, eyelids or skin and their triggering factors were assessed with specific questions.

RESULTS

A total of 10,743 individuals (5285 men and 5458 women) were included in the study. Among them, 48.2% reported having sensitive skin and 46.0% reported having "sensitive eyes". "Sensitive eyes" were more frequently reported by women (46.5%) than men (39.4%) in all countries, with the exception of China. The presence of "sensitive eyes" was more frequent if skin was very sensitive. More than half of subjects with "sensitive eyes" declared that their triggering factors were exposure to sunlight, dust, touch pad screens or computer screens or dry air. They were more exposed to pollution and tobacco. Their phototype (including eye color) was lighter.

DISCUSSION/CONCLUSION

This large study shows that self-declared "sensitive eyes" are very frequent and commonly associated with sensitive skin. Triggering factors of sensitive eyes are more specific.

Deep learning-based image analysis for automated measurement of eyelid morphology before and after blepharoptosis surgery

BACKGROUND AND AIM

Eyelid position and contour abnormality could lead to various diseases, such as blepharoptosis, which is a common eyelid disease. Accurate assessment of eyelid morphology is important in the management of blepharoptosis. We aimed to proposed a novel deep learning-based image analysis to automatically measure eyelid morphological properties before and after blepharoptosis surgery.

METHODS

This study included 135 ptotic eyes of 103 patients who underwent blepharoptosis surgery. Facial photographs were taken preoperatively and postoperatively. Margin reflex distance (MRD) 1 and 2 of the operated eyes were manually measured by a senior surgeon. Multiple eyelid morphological parameters, such as MRD1, MRD2, upper eyelid length and corneal area, were automatically measured by our deep learning-based image analysis. Agreement between manual and automated measurements, as well as two repeated automated measurements of MRDs were analysed. Preoperative and postoperative eyelid morphological parameters were compared. Postoperative eyelid contour symmetry was evaluated using multiple mid-pupil lid distances (MPLDs).

RESULTS

The intraclass correlation coefficients (ICCs) between manual and automated measurements of MRDs ranged from 0.934 to 0.971 (p < .001), and the bias ranged from 0.09 mm to 0.15 mm. The ICCs between two repeated automated measurements were up to 0.999 (p < .001), and the bias was no more than 0.002 mm. After surgery, MRD1 increased significantly from 0.31 ± 1.17 mm to 2.89 ± 1.06 mm, upper eyelid length from 19.94 ± 3.61 mm to 21.40 ± 2.40 mm, and corneal area from 52.72 ± 15.97 mm2 to 76.31 ± 11.31mm2 (all p < .001). Postoperative binocular MPLDs at different angles (from 0° to 180°) showed no significant differences in the patients.

CONCLUSION

This technique had high accuracy and repeatability for automatically measuring eyelid morphology, which allows objective assessment of blepharoptosis surgical outcomes. Using only patients' photographs, this technique has great potential in diagnosis and management of other eyelid-related diseases.

Management of Traumatic Soft Tissue Injuries of the Face

Facial soft tissue injuries encompass a broad spectrum of presentations and often present significant challenges to the craniofacial surgeon. A thorough and systematic approach to these patients is critical to ensure that the patient is stabilized, other injuries identified, and the full extent of the injuries are assessed. Initial management focuses on wound cleaning with irrigation, hemostasis, and debridement of nonviable tissue. Definitive management is dependent on the region of the face involved with special considerations for critical structures such as the globe, lacrimal apparatus, facial nerve, and parotid duct. Following sound surgical principles, these injuries can be managed to maximize both functional and aesthetic outcomes while minimizing complications.

[Repair of eyelid and periocular soft tissue defects with Pacman flap]

Objective

To explore the effectiveness and safety of Pacman flap for repair of eyelid and periocular soft tissue defects.

Methods

The clinical data of 12 patients who underwent repair of eyelid and periocular soft tissue defects with Pacman flap between April 2015 and September 2020 was retrospectively reviewed. There were 5 males and 7 females, aged from 18 to 87 years, with a median age of 63 years. The disease duration ranged from 6 months to 50 years, with a median time of 3 years. The defect was located on the lateral eyelid in 5 cases, inferior eyelid in 3 cases, inferior and medial eyelid in 2 cases, inferior and lateral eyelid in 2 cases, and lateral eyebrow in 1 case. Pathological diagnosis included 4 cases of basal cell carcinoma, 4 cases of squamous cell carcinoma, 1 case of junction nevus, 1 case of intradermal nevus, 1 case of seborrheic keratosis, and 1 case of keratoacanthoma. The size of defects ranged from 1.4 cm×1.2 cm to 5.5 cm×5.0 cm. According to the skin mobility and toughness around the defects, Pacman flaps with the size of 1.6 cm×1.4 cm to 10.0 cm×6.0 cm were designed and advanced to repair the defects.

Results

All flaps survived completely with no necrosis. One patient had infection, and another patient had partial wound dehiscence, but the wounds healed after dressing change without further debridement. Other patients all recovered successfully. The follow-up time ranged from4 to 51 months, with a median time of 12 months. No recurrence and metastasis occurred, and the scars were invisible without deformity of eyelid and brow. All patients were satisfied with the aesthetic and functional outcomes of the eyes.

Conclusion

Pacman flap is a simple and feasible technique for repair of eyelid and periocular soft tissue defects, with satisfactory effectiveness.

The application of a retrograde postauricular island flap in reconstructing periorbital region defects

BACKGROUND

Reconstruction of periorbital region defects is thought to be one of the most challenging areas in reconstructive plastic surgery. This paper describes our experiences with the application of retrograde postauricular island flaps in reconstructing periorbital region defects.

METHODS

Between November 2008 and June 2019, 16 patients with periorbital region defects underwent treatment using a retrograde postauricular island flap. The flap is designed with two portions: 1) the pedicle segment only with the superficial temporal fascia and 2) the flap segment in the posterior auricular region with non-hair-bearing full-thickness tissue. Intraoperatively, the vascular networks between the postauricular and the superficial temporal vessels were preserved. The flap was then transferred to the receipt area after passing through a subcutaneous tunnel. The donor site was directly closed in the postauricular sulcus by advancing the posterior scalp flap.

RESULTS

All the periorbital region defects were reconstructed in one-stage surgery. All the flaps survived without venous congestion. The size of the harvested flaps varied from 5.0 × 2.5 cm to 7.5 × 5 cm. The colour of the transferred flaps matched the surroundings of the receipt region, and the eyelids functioned well.

CONCLUSION

A retrograde postauricular island flap is a good choice for the reconstruction of periorbital region defects. The flap can be useful for the reconstruction of the periorbital region, since it uses similar colours and textures. In addition, it permits a "one-stage" reconstruction with less conspicuous donor site scars behind the auricle.

A technique for eyelid margin repair without use of marginal sutures

Purpose: To describe and evaluate a novel technique for eyelid margin repair without the use of marginal sutures.Methods: A retrospective chart review of patients who underwent primary repair of full-thickness lid margin defects using the described technique between March 2013 and May 2019 was performed. Clinical data such as indication for repair as well as size of defect was analyzed. The primary outcome measures included presence or absence of lid notching and post-operative complications such as wound dehiscence, infection, eyelid malposition, and keratopathy. Descriptive statistics were used.Results: A total of 31 cases were identified. Five were excluded in post-operative analysis for follow-up of less than 2 weeks. The average age was 59.6 years (range 22-88) and 54.8% of patients were female. Average follow up in post-operative analysis group was 17.0 weeks (range 2 weeks to 42 months). Average defect size was 5.77 mm (range 2-12 mm). Reasons for repair were resection of eyelid lesion in 25/31 (80.6%), floppy eyelid in 4/31 (12.9%), trauma in 1/31 (3.2%), and trichiasis in 1/31 (3.2%). Post-operative eyelid notching was noted in 2/26 patients (7.7%), and there were no instances of wound dehiscence, infection, eyelid malposition, or keratopathy noted.Conclusions: Our technique for full-thickness eyelid margin repair without the use of marginal sutures successfully repairs defects up to 12 mm for various indications. We observed comparable cosmetic outcomes to previously described techniques as well as a low rate of complications using our technique.

CLEAR - Anatomy and physiology of the anterior eye

A key element of contact lens practice involves clinical evaluation of anterior eye health, including the cornea and limbus, conjunctiva and sclera, eyelids and eyelashes, lacrimal system and tear film. This report reviews the fundamental anatomy and physiology of these structures, including the vascular supply, venous drainage, lymphatic drainage, sensory innervation, physiology and function. This is the foundation for considering the potential interactions with, and effects of, contact lens wear on the anterior eye. This information is not consistently published as academic research and this report provides a synthesis from all available sources. With respect to terminology, the report aims to promote the consistent use of nomenclature in the field, and generally adopts anatomical terms recommended by the Federative Committee for Anatomical Terminology. Techniques for the examination of the ocular surface are also discussed.

Anatomical and physiological considerations in scleral lens wear: Eyelids and tear film

Scleral lenses can affect a range of anterior segment structures including the eyelids and the tears. The eyelids, consisting of the outer skin layer, the middle tarsal plate, and the posterior palpebral conjunctiva, provide physical protection and house the meibomian glands and cilia which have important and unique functions. Tears consist of a mix of aqueous, mucus, and lipidomic components that serve vital functions of lubricity, protection, and nourishment to the ocular surface. Both the eyelids and the tear film interact directly with scleral lenses on the eye and can affect but also be impacted by scleral lens wear. The purpose of this paper is to review the anatomy and physiology of the eyelids and tear film, discuss the effects and impacts of the scleral lenses on these structures, and identify areas that require further research.

Reconstruction of Mohs Defects Located in the Head and Neck

BACKGROUND

Defects following Mohs micrographic surgery (MMS) can range in size from small defects requiring linear closure to large defects needing flap coverage. Reconstruction is dependent on defect size and facial aesthetic unit involvement. The aim of this study was to review the types of facial reconstruction per aesthetic unit involvement and describe their outcomes.

METHODS

All data were retrieved for patients ≥18 years who underwent multidisciplinary treatment including dermatological MMS and plastic surgical reconstruction at a single tertiary hospital center (2001-2017). Patient characteristics, tumor pathology, surgical specifics, reconstructive modalities, and surgical outcomes were analyzed.

RESULTS

A total of 418 patients were included. Patients were predominantly White, non-Hispanic (97%) and female (58%) with a mean age of 60 ± 13.9 years. Tumor pathology was predominantly basal cell carcinoma in 73% of all cases followed by squamous cell carcinoma in 14%. The nasal aesthetic unit was mostly affected (50%). Local advancement flaps and different types of grafts were used in 51% and 25% of reconstructions, respectively. Complications were observed in 3% and local cancer recurrence in 4% of the patients. Scar revision was needed in 6% of the patients.

CONCLUSION

Reconstruction of facial defects after Mohs micrographic surgery can be challenging due to its technical complexity and aesthetic implications. There were differences in complications in reconstructions performed within the same day versus 1 week, with a majority of complications occurring within same-day Mohs reconstructions. A multidisciplinary structured approach, which incorporates patient-reported outcomes, may be needed to optimize surgical results.

A Unifying Algorithm in Microvascular Reconstruction of Oral Cavity Defects Using the Trilaminar Concept

Although many algorithms exist to classify oral cavity defects, they are limited by either considering a single subsite or failing to provide a concise reconstructive algorithm for the breadth of defects. Based upon our experience as a tertiary referral center, a unifying algorithm is presented that guides free flap selection in this heterogenous population.

Reconstruction of Upper Eyelid Defects Secondary to Malignant Tumors with a Newly Modified Cutler-Beard Technique with Tarsoconjunctival Graft

Purpose

We describe a modification of Cutler-Beard's technique, using a contralateral tarsoconjunctival graft, in patients who underwent excision of large malignant tumors of the upper eyelid.

Methods

This is an interventional retrospective review (clinical study) of ten cases, with age range from 64 to 86 years (mean: 71.2 years ± 6.49) with malignant upper eyelid tumors, operated by the same surgeon (AB-G), between 2011 and 2016. The resulting defects were reconstructed using a modification of Cutler-Beard's technique. A tarsoconjunctival graft was harvested from the contralateral upper eyelid, with an extra 3 mm of conjunctiva from the superior edge of tarsus and was attached to the upper eyelid defect, different from that previously described. Follow-up ranged between 24 and 60 months (mean: 41.6 ± 9.87). Functional, cosmetic outcomes and postoperative complications were evaluated.

Results

No upper eyelid retraction, eyelid margin entropion, or graft retraction was observed in any of the cases. All of the patients were satisfied with the aesthetic result.

Conclusion

This technique allows us to safely inset a suitable graft on the ocular surface, with sufficient blood supply, resulting in a stable margin and good contour.

Association of sensitive skin with sensitive corneas and sensitive eyelids

BACKGROUND

Sensitive scalp or irritable bowel syndrome has been previously shown to be associated with sensitive skin. We wondered whether sensitive eyelids and sensitive eyes could also be associated with sensitive skin.

METHODS

A cross-sectional epidemiological study was carried out on a representative sample of French people, according to the quota method, using a questionnaire.

RESULTS

A total of 2048 subjects were included in the present study. Notably, 52.2% declared sensitive eyes, which was more frequent in women than in men. The subjects who reported sensitive eyes were more numerous according to the severity of skin sensitivity, the severity of sleep disorders and the presence of bright eyes. More than half of the subjects with sensitive eyes thought that they were sensitive to sun exposure, dust, computer or touch pads or dry air. The presence of sensitive eyelids was reported by 18.65% (more frequent in women) and was associated with sensitive skin and sensitive eyes, sun exposure and exposure to dust.

CONCLUSION

This study is the first to investigate sensitive eyelids or sensitive eyes. Sensitive eyelids can be considered a localization of sensitive skin. The concept of sensitive eyes is not commonly used by ophthalmologists and remains to be more precisely defined.

Normobaric oxygen therapy increases cartilage survival ratio in auricular composite grafting in rat models

PURPOSE

This study aims to clarify whether normobaric oxygen therapy improves the survival of auricular composite grafts in rats.

METHODS

For 10 male SD rats, 1.5 cm2 composite grafts were harvested from bilateral ear regions including whole auricles. The harvested grafts were transferred caudally and sutured there. The 10 rats were randomly divided into two groups and kept for 21 days in two different circumstances. The first group (Control group: five rats carrying 10 grafts) was kept in room air (20% oxygen) throughout the 21 days, and the second group-named NBO (normobaric oxygen) group (five rats carrying 10 grafts)-was kept in normobaric 60% oxygen for 3 days and then in room air for 18 days. All the 10 rats were sacrificed on the 21st day. Surviving areas of the grafts and the height of the surviving auricular cartilage were examined for statistical comparison of the two groups. Furthermore, the conditions of chondrogenesis occurring around the perichondrium were compared between the two groups.

RESULTS

Surviving areas did not present statistically significant differences between the two groups. The height of surviving cartilage was significantly greater for the NBO group (2610 ± 170 SD µm) than that for the Control group (1720 ± 190 SD µm). Chondrogenesis occurred at positions more distant from the recipient bed in the NBO group than that in the Control group.

CONCLUSION

Normobaric oxygen therapy increases the thickness of surviving cartilage in auricular composite grafting in rats, thus suggesting that NBO therapy may also be effective in composite grafting for humans.

Three-Dimensional Topography of the Emerging Point of the Ophthalmic Artery

BACKGROUND

During periorbital noninvasive and surgical procedures, there is the risk of iatrogenic injury to the emerging point of the ophthalmic artery. This study aimed to determine the three-dimensional location of the emerging point of the ophthalmic artery and to provide clinicians with anatomical information that would help them to avoid associated complications.

METHODS

Seventeen hemifaces of the emerging point of the ophthalmic artery from 10 Korean and seven Thai cadavers were dissected and scanned by a three-dimensional scanner. The emerging points of the ophthalmic artery of 30 healthy Korean volunteers were also detected using an ultrasound imaging system.

RESULTS

The transverse distance from the medial canthus to the emerging of the ophthalmic artery was 3.8 ± 1.0 mm medially, and the vertical distance was 14.0 ± 2.9 mm superiorly. The transverse distance from the midline was 16.5 ± 1.7 mm to the emerging point of the ophthalmic artery and 20.0 ± 2.0 mm to the medial canthus. The measured depth from the skin surface to the emerging point of the ophthalmic artery was 4.8 ± 1.7 mm by means of three-dimensional scanning and 4.5 ± 1.1 mm using ultrasound detection. The vertical distance from the inferior margin of the superior orbital rim to the emerging point of the ophthalmic artery was 5.3 ± 1.4 mm.

CONCLUSION

These data inform clinicians about the anatomical three-dimensional location of the emerging point of the ophthalmic artery, which will help them to avoid iatrogenic injury when they are performing periorbital clinical procedures.
