A swinging upper eyelid approach for excision of lacrimal gland masses.

PURPOSE: To describe a novel transconjunctival technique for excision of well-defined masses of the orbital lobe of the lacrimal gland. METHODS: Case series of three patients undergoing excision of a well-defined mass of the orbital lobe of lacrimal gland using a swinging upper eyelid flap. This technique entails a supratarsal conjunctival incision combined with lateral canthotomy and superior cantholysis. RESULTS: Complete removal of the mass without visible scars was achieved in all cases. There were no complications related to this approach. CONCLUSION: The swinging upper eyelid approach produces a wide exposure of the superolateral orbit. It allows safe removal of large lacrimal gland masses without the need for bone removal, while affording acceptable cosmesis.

Clinical characteristics and surgical outcomes of transcutaneous versus transconjunctival excision of Wolfring gland ductal cysts.

PURPOSE: To analyze the clinicopathological characteristics and surgical outcomes of patients with Wolfring gland ductal cysts (WGDCs). METHODS: A retrospective, consecutive, interventional comparative case series was performed over a period of 7 years. Data on demographic and clinical characteristics, pathological findings and outcomes of surgically excised cysts were collected. A comparison between the transconjunctival and transcutaneous approaches was also assessed. RESULTS: Forty-eight patients (48 eyelids) were included in the final analysis. The most common presenting symptom was painless eyelid swelling (81.3%). The median symptom duration was 11.5 months (IQR, 18.25). The upper eyelid was involved in 31 (64.6%) patients, 29/31 of whom had cysts in a medial or centromedial location. Forty-five (93.8%) cysts were bluish gray and transilluminable with clear contents on lid eversion and a median largest dimension of 22 mm (IQR, 8). A transverse conjunctival fibrotic band was observed along the proximal tarsal border in the cyst area in all patients. Signs of chronic trachoma were noted in 38 (79.2%) patients. Preoperative significant ptosis was present in 28/31 (90.3%) of the upper eyelid cysts. Thirty cysts (62.5%) were excised through the skin, and 18 cysts (37.5%) were excised transconjunctivally. Intraoperative cyst rupture, the need for conjunctival grafting and postoperative residual upper lid ptosis were significantly greater in the transconjunctival group (p = 0.009, p < 0.001, and p = 0.016, respectively). CONCLUSION: The present study highlights the clinicopathological characteristics of a relatively large series of surgically excised WGDCs. Transcutaneous excision of WGDCs has proven to be an effective treatment with fewer adverse sequelae than the transconjunctival approach.

Targeted therapy and immunotherapy for orbital and periorbital tumors: a major review.

Traditionally, for patients who are poor candidates for surgery and/or radiotherapy, palliative chemotherapy is often offered but with significant toxic side effects. However, recent advancements in our understanding of tumor biology and molecular genetics have brought new understanding to the molecular pathways of certain tumors and cancers. This has ushered in a new era of precision medicine specific to a tumor or cancer treatment pathway (targeted therapy) or directed to host-tumor responses (immunotherapy). This article will focus on recent updates in the application of available targeted and immunotherapy for managing orbital and periorbital tumors and tumor-like conditions, which include cutaneous basal cell carcinoma, cutaneous squamous cell carcinoma, cutaneous melanoma, Merkel cell carcinoma, sebaceous gland carcinoma, solitary fibrous tumor, dermatofibrosarcoma protuberans, orbital meningioma, neurofibromatosis, Langerhans cell histiocytosis, ocular adnexal lymphoma, orbital lymphatic malformation, and adenoid cystic carcinoma.

Negative interactions and virulence differences drive the dynamics in multispecies bacterial infections.

Bacterial infections are often polymicrobial, leading to intricate pathogen-pathogen and pathogen-host interactions. There is increasing interest in studying the molecular basis of pathogen interactions and how such mechanisms impact host morbidity. However, much less is known about the ecological dynamics between pathogens and how they affect virulence and host survival. Here we address these open issues by co-infecting larvae of the insect model host Galleria mellonella with one, two, three or four bacterial species, all of which are opportunistic human pathogens. We found that host mortality was always determined by the most virulent species regardless of the number of species and pathogen combinations injected. In certain combinations, the more virulent pathogen simply outgrew the less virulent pathogen. In other combinations, we found evidence for negative interactions between pathogens inside the host, whereby the more virulent pathogen typically won a competition. Taken together, our findings reveal positive associations between a pathogen's growth inside the host, its competitiveness towards other pathogens and its virulence. Beyond being generalizable across species combinations, our findings predict that treatments against polymicrobial infections should first target the most virulent species to reduce host morbidity, a prediction we validated experimentally.

The Overweight and Obese Patient in Oculofacial Plastic Surgery: A Narrative Review.

PURPOSE: The oculofacial plastic surgeon will more frequently encounter challenges related to overweight and obese patients as the incidence rises. There is a paucity of data in the oculofacial plastic surgical literature regarding this topic. The goal of this review is to detail the role obesity plays in the perioperative course and the considerations for a surgeon treating this patient population. METHODS: The authors conducted a computerized search using PubMed, Embase, and Google Scholar. The search terms used were "(obesity OR overweight) AND surgery," "(obesity OR overweight) AND oculoplastic," "(obesity OR overweight) AND oculofacial," "(obesity OR overweight) AND 'facial plastic surgery', " "(obesity OR overweight) AND 'bariatric surgery', " "(obesity OR overweight) AND (pre-operative OR post-operative OR intraoperative," " (obesity OR overweight) AND complications," "(obesity OR overweight) AND (facial plastic surgery) AND complications)," "(obesity OR overweight) AND eyelid," "(obesity OR overweight) AND (nasolacrimal OR 'nasolacrimal duct')," "(obesity OR overweight) AND IIH," "(obesity OR overweight) AND exophthalmos." RESULTS: A total of 127 articles, published from 1952 to 2022 in the English language or with English translations were included. Articles published earlier than 2000 were cited for foundational knowledge. References cited in the identified articles were also used to gather further data for the review. CONCLUSIONS: Overweight and obese patients pose specific challenges that the oculofacial plastic surgeon should be aware of to better optimize patient outcomes. Multiple comorbidities, poor wound healing, and nutritional deficits all contribute to the complications experienced in this patient population. Further investigation on overweight and obese patients is needed.

Characteristics of Orbital Injuries Associated with Maxillofacial Trauma.

INTRODUCTION: The incidence of ocular injury associated with maxillofacial trauma remains poorly defined, with reported rates ranging from 0.8% to 92%. Our study aims to more accurately characterize ocular injuries associated with midface fractures. METHODS: We performed a retrospective review of 1677 patients from 2015 to 2020 with midface fractures at a Level I trauma center. Isolated nasal bone and frontal process of the maxilla fractures were excluded. Demographic information, mechanism of injury, need for surgery, and ophthalmologic findings were documented. Statistical analysis was conducted using SPSS. RESULTS: 773 patients between the ages of 15 and 92 were identified. Trauma most commonly resulted from assault (63.8%). The association between the mechanism of injury and ocular injury was statistically significant (p = 0.003), with 78.6% of gunshot wounds and 44.3% of assault patients having an ocular injury. The Ophthalmology service evaluated 62.6% of cases preoperatively. Minor ocular injury occurred in 36% of patients, including 46.1% of isolated orbital floor, and 28.2% of zygomaticomaxillary complex fractures. Major ocular injury occurred in 10.5% of patients. CONCLUSIONS: Over 10% of patients with midface fractures were found to have major ocular injuries. Ophthalmologic exams should be performed for all patients with midface fractures to guide clinical decision making and prevent further intraoperative ocular insults. LEVEL OF EVIDENCE: Level 4. This study represents a retrospective cohort study analyzing ocular injuries detected in patients presenting to a Level I trauma center with maxillofacial fractures between 2015 and 2020 Laryngoscope, 133:1624-1629, 2023.

The transconjunctival orbitotomy: A versatile approach to the orbit and beyond.

In the management of orbital disorders and defects, minimally invasive surgical approaches have become increasingly efficient for their reduction of operative trauma and access without compromise of therapeutic benefit or diagnostic yield. Various approaches have focused on bone- and canthal-sparing techniques and concealed and small skin incisions. We review the current state of knowledge of procedures to enter the orbit via the conjunctiva. Any quadrant of the orbit can be accessed via the conjunctiva. Surgical incisions involve the orbital palpebral, forniceal, and bulbar conjunctiva. According to the location, nature, and size of the lesion, the transconjunctival orbitotomy can be used as a single procedure, in combination with a caruncular approach or as an adjunct in a multidisciplinary procedure for lesions extending deep into or outside the orbit. The working space and field of operating view can be expanded by releasing the horizontal tension of the eyelid with a lateral cantholysis, lateral paracanthal blepharotomy, or medial lid split procedure. Complications related to the conjunctival incision are reduced to dry eye disease.

Combined levator and frontalis muscle advancement flaps for recurrent severe congenital ptosis.

BACKGROUND: To evaluate the outcomes of combined levator resection and frontalis muscle advancement for surgical management of recurrent severe congenital ptosis. DESIGN: Retrospective, nonrandomized interventional case series. METHODS: A retrospective review was performed of patients who underwent combined levator resection and frontalis muscle advancement for recurrent congenital ptosis between 2017 and 2020. Inclusion criteria were levator function of 4 mm or less and margin reflex distance 1 (MRD1) of 0 mm or less. Main outcome measures were postoperative MRD 1, lagophthalmos, lash angle, and grades of eyelid contour and crease. The outcomes were assessed by reviewing medical charts and photographs. RESULTS: Thirty-one patients (35 eyelids) met the inclusion criteria. The mean preoperative MRD1 was -1.14 ± 1.56 mm, which improved to 3.93 ± 0.52 mm with an average lagophthalmos of 0.91 ± 0.74 mm at the last follow-up. A total of 91.4% of eyelids had excellent eyelid contour, crease, and eyelash angle at the final follow-up. One eyelid required revision surgery. There were no other significant complications. CONCLUSIONS: For poor function recurrent congenital ptosis, combining levator resection and frontalis muscle advancement is an effective method that results in long-term correction with cosmetically pleasing outcomes and minimal complications.

Eyelid Blink Lagophthalmos and Blinking Velocity Changes After External Transcutaneous Dacrocystorhinostomy: A Prospective Study.

PURPOSE: To investigate the changes in eyelid blinking dynamics after external dacryocystorhinostomy (DCR). DESIGN: Prospective before-and-after study with follow-up. METHODS: Patients undergoing external DCR surgery for primary acquired nasolacrimal duct obstruction were observed using high-speed videography that recorded eyelid blinking of both eyes for a total duration of 4 minutes at a rate of 120 frames per second. These recordings were taken before the surgical procedure, on postoperative day 3, and then at 1 week, 1 month, and 3 months after the DCR surgery. A total of 3 random blinks were selected and isolated from each video recording for data analysis. For each blink, lagophthalmos and eyelid blinking velocity were calculated for the operated eye, and their values were then compared with those calculated for the contralateral, nonoperated eye. RESULTS: Data were obtained for 22 patients. Operated eyes showed large postoperative lagophthalmos on postoperative day 3, with a mean of 56.58% ± 52.63% of the palpebral fissure height. Gradual improvement of the lagophthalmos occurred over the next follow-up visits, and reached a mean of 31.24% ± 36.71% at follow-up visit 3 months postoperatively. The velocity of eyelid blinking showed a significant reduction for the operated eyes, with gradual improvement over 3 months. CONCLUSIONS: Postexternal DCR eyelid blinking changes included significant blink lagophthalmos with decreased velocity of eyelid blinking which gradually improved over the 3-month follow-up period. A longer follow-up period may be required to confirm if eyelid blinking lagophthalmos and velocity will return to baseline levels.

Epidemiologic Differences and Management of Eyelid Lesions in the Pediatric Population.

PURPOSE: To report the relative incidence of excised pediatric eyelid lesions and describe the correlation between the clinical and pathology diagnosis. METHODS: This was a retrospective analysis of 137 consecutive pathology-confirmed eyelid lesions excised at a U.S. quaternary children's hospital system. Chalazion was excluded from this study. RESULTS: Benign non-cystic epithelial lesions comprised 48.2% of all excised lesions, followed by mesenchymal (14.6%) and cystic (10.2%) lesions. The most common lesions were molluscum contagiosum (21.9%) and verruca vulgaris (19.0%). Hispanic White race represented 62.0% of cases, followed by non-Hispanic White (23.3%) and Black (8.8%). There were no malignant lesions. A specific preoperative clinical diagnosis was attempted in 70.1% of cases. Of these, 60.4% had a matching histopathology. CONCLUSIONS: The authors report a higher proportion of molluscum contagiosum and verruca vulgaris when compared to the literature; these differences may suggest geographic variance, management preference, or a general increase in incidence. Correlation with pathology showed the clinical diagnosis of eyelid lesions can be challenging even for ophthalmologists. However, malignancy in pediatric eyelid lesions is rare and submission for histopathology may be safely omitted, except in cases with atypical features or suspicion for syndromic disease. The decision for surgery should be methodically approached and take into consideration the most likely diagnosis, natural history of the disease, sociopsychological impact, anesthesia risk, and resource burden.

Bilateral orbital inflammation in a 6-month old with SARS-CoV-2 infection.

A 6-month-old female presented with bilateral periorbital edema for 7 days. Laboratory testing was significant for active SARS-CoV-2 infection. Neuroimaging demonstrated soft tissue changes within the bilateral orbits and enlargement of the bilateral lacrimal glands. Although the patient initially improved with corticosteroid treatment, she later returned with recurrent left periorbital and eyelid edema. Orbital biopsy was performed and demonstrated findings in the lacrimal gland and the adjacent fibroconnective tissues that are similar to those of prior lung specimens seen in SARS-CoV-2 patients. Final diagnosis was bilateral orbital inflammation with features presumed secondary to SARS-CoV-2 infection. To the best of our knowledge, this is one of the first reports to document bilateral orbital inflammation as a sign of SARS-CoV-2 infection in the pediatric population with the associated pathological findings.

#OculoplasticsandSocialMedia: a review of social media in oculoplastics and relevant subspecialties.

The permeation of social media into life almost goes without bounds and medicine is no exception. While social media holds great potential for physicians and medicine, it also comes with concurrent spread of disinformation. This increases the importance of evidence-based information from qualified physicians on social media.Although the definition of social media is broad, in general, it refers to the use of web-based platforms to connect one human to another. In oculoplastic surgery, these relationships can be physician to physician, physician to patient, patient to patient, and vendor to physician. These relationships mostly involve education, social support, and advertising, but can also include research and government advocacy. The purpose of this review is to evaluate the current utilization of social media in oculoplastic surgery and relevant subspecialties.

Congenital alacrima.

The congenital absence of tear production or alacrima is a distinctively unusual clinical sign that harbors a wide variety of etiologies. While alacrima can be only isolated to the lacrimal system, it is more often associated with progressive multisystem involvement from underlying genetic disorders. Recognizing the subtle ocular signs in these diseases will promote a timely diagnosis and management before potential life-threatening consequences occur. Hence, the current article will review the ophthalmological findings, systemic manifestations, genetic associations, and differential diagnosis of congenital alacrima.

Optic nerve biopsy in leukemic infiltrative optic neuropathy: a case report and review of the literature.

Optic nerve infiltration is a rare but known complication of the central nervous system (CNS)-involving lymphoma and leukemic disorders. The diagnosis is often presumed and patients are empirically treated with systemic therapy and/or local radiation. Optic nerve biopsy is usually avoided due to the risk of permanent vision loss secondary to the procedure. We present a case of biopsy-proven leukemic optic neuropathy without optic nerve sheath or cerebrospinal fluid (CSF) involvement in a patient previously in remission from T-cell prolymphocytic leukemia (T-PLL). To our knowledge, this is the first documented case of T-PLL with biopsy-proven optic nerve invasion without CSF involvement and suggests possible perineural invasion or a sanctuary site from chemotherapy. We suggest that for patients with poor vision and suspected leukemic infiltration without other evidence of CNS involvement, both optic nerve and optic sheath biopsy should be performed for diagnosis and treatment.
