Adnexal squamous cell carcinoma: incidence of eyelid margin involvement.

PURPOSE: We aimed to perform a review of facial and periorbital squamous cell carcinoma (SCC) cases to assess the relative incidence of eyelid margin involvement. METHODS: This is a retrospective review of all patients with biopsy-proven SCC who were evaluated at a single oculoplastic surgery practice from 2007 to 2019. The charts were reviewed for the anatomical location of the malignancy, and those involving the eyelid were further divided into marginal and non-marginal lesions. Statistical analysis was performed using a one proportion z-test. RESULTS: A total of 76 patients with a diagnosis of biopsy-proven periorbital and facial SCC were identified, 67 involved the ocular adnexa. Thirty-nine (58.2%) patients had lesions located on the eyelid. Of these, 33 (84.6% p < 0.0001, 95% CI 69.45-94.13) had lesions located at the margin, six of the 39 lesions were non-marginal. The remaining lesions were present within the brow (n = 10, 14.9%), medial canthus (n = 10, 14.9%), palpebral conjunctiva (n = 1, 1.5%), or orbit (n = 1, 1.5%). In six patients (8.9%) lesions involved multiple anatomic subunits. CONCLUSION: We present our investigation of the incidence of SCC of the marginal vs. non-marginal eyelid, revealing a statistically significant increased involvement of the eyelid margin. Future investigations are necessary to further elucidate the vulnerability of the eyelid margin to the development of SCC in particular in regards to the role of the unique genetic expression profile of eyelash follicular stem cells.

Autologous Fat Transfer Harvest-site Complications: Incidence, Risk Factors, and Management.

PURPOSE: Autologous fat transfer is an effective tool for volume restoration to the aging face. Although numerous reports exist regarding injection site complications, there is limited data on donor-site morbidity in the cosmetic surgery literature. METHODS: This study is a large-scale retrospective review to determine incidence of fat harvest-site complications, identify risk factors, and describe management strategies. Records of all patients who underwent autologous fat harvesting and facial grafting at a single oculofacial plastic surgery practice from 2010 to 2019 were reviewed. Patient demographics and clinical data were collected and assessed. A statistical analysis was performed using a two-tailed T-test with p values of <0.05 considered significant. RESULTS: Four-hundred sixteen patients were followed for an average of 6.2 months postoperatively. There was an overall 5.5% harvest-site complication rate. There was no correlation of harvest-site complications with gender (p = 0.249) or age (p = 0.881). Harvest location did not significantly correlate with complication rate. The most common complications were contour irregularities, prolonged induration, and prolonged erythema. Low body mass index was associated with higher complication rate (p = 0.003), even when excluding those patients with contour irregularities (p = 0.001). Various treatment modalities were used to manage donor-site morbidity with consistent improvement. CONCLUSIONS: Autologous fat transfer used for facial volume augmentation has low donor-site morbidity. Minor harvest-site complications occur more commonly in patients with low body mass index, irrespective of age, gender, or fat source.

Rifle Blast Exacerbating Hearing Loss in a Patient Treated With Teprotumumab for Thyroid Eye Disease.

Teprotumumab is a promising new immunomodulatory therapy for thyroid eye disease. One unique adverse effect observed in clinical trials was hearing impairment; however, all adverse auditory effects in prior clinical trials resolved spontaneously after completion of teprotumumab therapy. The authors present a case of a patient on teprotumumab for thyroid eye disease who experienced sustained hearing loss secondary to shooting a rifle without ear protection. In this case, it is suspected the teprotumumab infusions resulted in increased susceptibility of the inner ear hair cells to noise-induced trauma secondary to IGF-IR inhibition. Specific ear protection protocols may need to be implemented in the future for patients on teprotumumab therapy to prevent sustained hearing loss, especially for susceptible patient populations.

5-Fluorouracil With Microneedling Modulates Wound Healing in a Murine Model: An Immunohistochemical Analysis of Mechanism and Dose Efficacy.

PURPOSE: The purpose of this study is to assess the dose-dependent immunohistopathological effects of intradermal microneedle-delivered 5-fluorouracil (5-FU) for postincisional wound healing in a murine model. METHODS: A prospective experimental study was performed. Twelve hairless mice were randomized into 4 treatment groups for postincisional wound treatment: microneedling with topical saline, or microneeding with topically-applied 5-FU at concentrations of 25 mg/ml, 50 mg/ml, or 100 mg/ml. Two surgical wounds were created on each animal. Combination wound treatments were performed on postoperative days 14 and 28, and cutaneous biopsies were obtained on day 56. Specimens were analyzed by a dermatopathologist, blinded to the treatment group, for collagen thickness, lymphocytic infiltration, histiocytic response, sub-epidermal basement membrane zone thickness, and myofibroblast density. RESULTS: Histopathologic evaluation showed increased collagen thickness, lymphocyte infiltration, and granuloma density in the groups undergoing microneedling treatment with 5-FU, compared to saline. Immunohistochemical analysis revealed a trend toward thicker basement membranes with higher concentrations of 5-FU used, reaching statistical significance between controls and those treated with 100 mg/ml 5-FU ( p = 0.0493). A trend toward decreasing myofibroblast density with increasing doses of 5-FU was noted. No postincisional or treatment complications were observed. CONCLUSIONS: Our results demonstrate that microneedling is an effective topical subepithelial drug delivery system, and further suggest a beneficial dose-dependent immunomodulatory effect of 5-FU on intermediate wound healing when used in combination with microneedling. We recommend a 5-FU dose at the mid-range 50 mg/ml concentration to simultaneously maximize efficacy and minimize complication risk.

Simultaneous presentation of orbital mantle cell lymphoma and endocrine mucin-producing sweat gland carcinoma.

Mantle cell lymphoma is a rare malignancy to present in the orbit, comprising only 1-5% adnexal lymphomas. Endocrine mucin-producing sweat gland carcinoma (EMPSGC) is an equally uncommon adnexal tumor of sweat gland origin that may present on the eyelid. Herein we present a case of a 77-year old man with no previous cancer history who presented with painless progressive left globe proptosis and an enlarging left upper lid margin lesion, ultimately determined upon biopsy to be simultaneous orbital mantle cell lymphoma with systemic involvement and isolated eyelid EMPSGC. The pathogenesis, clinical manifestation, and management for each rare disease entity are reviewed and concept of collision tumors is discussed.

Disseminated Coccidioidomycosis With Orbital Osteomyelitis and Periorbital Abscess.

Coccidioidomycosis osteomyelitis involving the orbital bones is exceedingly rare and is often misdiagnosed initially as other inflammatory or infectious conditions. No clear guidelines currently exist regarding appropriate management. The authors present an atypical presentation of disseminated coccidioidomycosis in an immunocompetent child with frontal bone superotemporal orbital rim osteomyelitis and associated periorbital abscess, successfully managed with surgical debridement through an upper eyelid crease incision.

Wound Dehiscence Following Upper Blepharoplasty: A Review of 2,376 Cases.

PURPOSE: There have been limited studies evaluating specifically the incidence of wound dehiscence following isolated upper blepharoplasty. This is a large-scale upper blepharoplasty review to evaluate the rate of wound dehiscence, to assess risk factors, and to analyze management outcomes. METHODS: A retrospective review was performed of all patients who underwent upper blepharoplasty at a single surgery center. All incisions were closed using either 6-0 fast-absorbing plain gut or polypropylene suture in a running fashion, with an additional interrupted suture near the lateral wound edge. Incidence of wound dehiscence was determined and further assessed by patient age (≤67 or >67 years), gender, preexisting medical conditions, smoking history, and suture type. RESULTS: A total of 1,190 patients (2,376 eyelids) met inclusion criteria. In total, there were 34 instances (1.4%) of wound dehiscence in 32 patients at an average 9 days (range, 0-30 days) following surgery. Evaluation of wound dehiscence rates by demographic factors revealed male gender to be a significant predictor of wound dehiscence (p = 0.0062). Age, hypertension, heart disease, and diabetes were not predictors of wound dehiscence. Lifetime smoking history increased risk for wound dehiscence (p < 0.0001). Use of fast-absorbing plain gut suture was also significantly associated with dehiscence, when compared with polypropylene (p = 0.0025). Multivariate analysis revealed male gender and fast-absorbing plain gut suture to be independent risk factors for wound dehiscence. Seventeen eyelids with wound separation were observed for second-intention healing, 1 underwent delayed scar revision. Fourteen eyelids were repaired primarily using suture and 3 with cyanoacrylate surgical skin adhesive. All patients reported satisfaction with their final outcome, and objective final healing was deemed satisfactory. CONCLUSIONS: Wound dehiscence following isolated upper blepharoplasty is rare and associated with male gender and fast-absorbing plain gut suture. Patients with wound separation may be successfully managed with individualized care.

Histologic Evaluation of Nonvisual Afferent Sensory Upper Eyelid Proprioception.

PURPOSE: Recent research has suggested a possible role for proprioception in ipsilateral frontalis activation in the setting of ptosis; however, there has not been any robust histologic or anatomic evidence to support this theory. To further elucidate proprioceptive structures in the eyelid, this investigation uses validated histologic techniques to explore the presence of proprioceptive structures or afferent neural networks in the Levator Palpebrae Superioris (LPS) and Müller muscle. METHODS: Müller muscle and LPS samples were evaluated by a laboratory with extensive experience with the histology of extraocular muscle proprioception. Immunofluorescence and confocal laser scanning microscopy were used to analyze the tissue samples. RESULTS: Thirty-four Müller muscle samples and 10 LPS samples were analyzed. Golgi tendon bodies and muscle spindles were not identified in the Müller muscle and LPS samples. This result is expected in the Müller muscle given that these structures are not typically present in smooth muscle, but noteworthy in the skeletal muscle of the LPS. Previously undescribed synaptophysin-positive free nerve terminals within the intermuscular connective tissue of the Müller muscle were identified. CONCLUSIONS: The nerve terminals identified are anatomically consistent with free nerve endings present in the extraocular muscles that have been implicated in proprioception. These findings advance our current knowledge of the ultrastructure of Müller muscle and the LPS and suggest a possible mechanism for proprioception in the upper eyelid that may have a role in ipsilateral brow elevation in the setting of ptosis.The authors describe proprioception in the upper eyelid: A histologic analysis.

Wiesner Nevus of the Eyelid.

A healthy 31-year-old female presented with an elevated vascular lesion on the right lower eyelid margin. Histology results from excisional biopsy demonstrated a range of intradermally nested atypical melanocytes with negative staining for BRCA1-associated protein 1, confirming the diagnosis of Wiesner nevus. Wiesner nevi may be a cutaneous hallmark of the BRCA1-associated protein 1-associated cancer susceptibility syndrome, and to our knowledge, this is the first report of such a lesion presenting anywhere on the ocular adnexa.

Ophthalmic Manifestations of Facial Dog Bites in Children.

PURPOSE: To characterize ophthalmic manifestations and periocular injuries of pediatric facial dog bites. METHODS: A retrospective review of all children younger than 18 years who sought medical attention after a dog bite to the face between January 1, 2003 and May 22, 2014 was performed at a large tertiary pediatric hospital. Data on type and location of injury, surgical intervention, and complications were collected. RESULTS: A total of 1,989 children aged 0.19 to 17 years were identified with dog bites. Dog bites to the face occurred in most patients (n = 1, 414 [71%]). Of those children with facial dog bite injuries, 230 (16%) suffered ophthalmic manifestations. The average age was 4.3 years. Eyelid injuries occurred in 227 (99%) of children, 47 (20%) sustained canalicular system injuries, 3 (1.3%) suffered corneal abrasions, and 2 patients sustained facial nerve injury resulting in lagophthalmos. No patients suffered vision loss. Complications occurred in 32 patients (14%), with the most common being epiphora in 9 patients (28%), upper eyelid ptosis in 8 (25%), and prominent scar formation in 4 patients (13%). Thirteen children (5.7%) needed one or more secondary procedure to correct complications. CONCLUSIONS: The authors report the clinical features and management on the largest series of ophthalmic and periocular injuries associated with pediatric facial dog bites. These injuries occur in about 1 in 6 dog bites to the face and primarily involve the ocular adnexa. Despite early and appropriate surgical management, complications and the need for revision surgery are relatively common.

Comparison of Revision Rates of Anterior- and Posterior-Approach Ptosis Surgery: A Retrospective Review of 1519 Cases.

PURPOSE: To compare revision rates for ptosis surgery between posterior-approach and anterior-approach ptosis repair techniques. METHODS: This is the retrospective, consecutive cohort study. All patients undergoing ptosis surgery at a high-volume oculofacial plastic surgery practice over a 4-year period. A retrospective chart review was conducted of all patients undergoing posterior-approach and anterior-approach ptosis surgery for all etiologies of ptosis between 2011 and 2014. Etiology of ptosis, concurrent oculofacial surgeries, revision, and complications were analyzed. The main outcome measure is the ptosis revision rate. RESULTS: A total of 1519 patients were included in this study. The mean age was 63 ± 15.4 years. A total of 1056 (70%) of patients were female, 1451 (95%) had involutional ptosis, and 1129 (74.3%) had concurrent upper blepharoplasty. Five hundred thirteen (33.8%) underwent posterior-approach ptosis repair, and 1006 (66.2%) underwent anterior-approach ptosis repair. The degree of ptosis was greater in the anterior-approach ptosis repair group. The overall revision rate for all patients was 8.7%. Of the posterior group, 6.8% required ptosis revision; of the anterior group, 9.5% required revision surgery. The main reason for ptosis revision surgery was undercorrection of one or both eyelids. Concurrent brow lifting was associated with a decreased, but not statistically significant, rate of revision surgery. Patients who underwent unilateral ptosis surgery had a 5.1% rate of Hering's phenomenon requiring ptosis repair in the contralateral eyelid. Multivariable logistic regression for predictive factors show that, when adjusted for gender and concurrent blepharoplasty, the revision rate in anterior-approach ptosis surgery is higher than posterior-approach ptosis surgery (odds ratio = 2.08; p = 0.002). CONCLUSIONS: The overall revision rate in patients undergoing ptosis repair via posterior-approach or anterior-approach techniques is 8.7%. There is a statistically higher rate of revision with anterior-approach ptosis repair.

Dilated Superior Ophthalmic Vein: Clinical and Radiographic Features of 113 Cases.

PURPOSE: Dilated superior ophthalmic vein (SOV) is an uncommon radiographic finding. The authors review the presentation, etiology, radiography, and visual implications of 113 patients with dilated SOV. METHODS: An observational case series and multicenter retrospective chart review were conducted. There were 113 patients with a dilated SOV. Outcome measures included patient demographics, clinical features, radiographic findings, diagnosis, and treatment, and treatment outcomes were assessed. RESULTS: Cases included 75 women (66%) and 38 men (34%) with a mean age of 49 ± 24 years (range, 0.4-90 years). Diagnoses fell under 6 categories: vascular malformation (n = 92, 81%), venous thrombosis (n = 11, 10%), inflammatory (n = 6, 5%), traumatic hemorrhage (n = 2, 2%), lymphoproliferative (n = 1, 1%), and infectious (n = 1, 1%). Imaging modalities utilized included MRI (n = 98, 87%), digital subtraction angiography (n = 77, 68%), CT (n = 29, 26%), and ultrasonography (n = 4, 4%). Disease status at last follow up included no evidence of disease (n = 57, 50%), alive with persistent disease (n = 53, 47%), and expired from disease (n = 3, 3%). Treatment and management was tailored to the underlying disease process with a mean follow up of 18 months (range, 1 day to 180 months). Visual impairment observed at presentation and last follow up across all cases was 26% and 22%, respectively. CONCLUSION: Dilated SOV is a rare radiographic finding resulting from a wide spectrum of etiologies with clinical implications ranging from benign to sight- and life-threatening. Dilated SOV is most often found with dural-cavernous fistula or carotid-cavernous fistula, orbital or facial arteriovenous malformation, and venous thrombosis. Recognition of this finding and management of the underlying condition is critical.

Increased Incidence of Rhino-Orbital-Cerebral Mucormycosis After Colorado Flooding.

In September 2013, central Colorado experienced a record amount of rainfall resulting in widespread flooding. Within 1 month of the flooding, 4 patients presented to the authors' institution with rhino-orbital-cerebral mucormycosis. This represents the largest number of cases ever recorded over a 1-month period. The authors hypothesize that the combination of immunocompromised status and environmental exposure resulted in the increased incidence.

Dacryocystitis As the Initial Presentation of Invasive Fungal Sinusitis in Immunocompromised Children.

Sino-orbital fungal infection is a rare, but life-threatening disease seen mainly in immunocompromised patients. While initial clinical impression may vary, dacryocystitis has rarely been described as the initial presenting sign. The authors present 2 pediatric cases of dacryocystitis as the initial sign of invasive fungal sinusitis. To their knowledge, this presenting sign has not been previously reported in the pediatric population. Management strategies and outcomes are discussed.

Axial Globe Position Measurement: A Prospective Multicenter Study by the International Thyroid Eye Disease Society.

PURPOSE: Identify a reproducible measure of axial globe position (AGP) for multicenter studies on patients with thyroid eye disease (TED). METHODS: This is a prospective, international, multicenter, observational study in which 3 types of AGP evaluation were examined: radiologic, clinical, and photographic. In this study, CT was the modality to which all other methods were compared. CT AGP was measured from an orthogonal line between the anterior lateral orbital rims to the cornea. All CT measurements were made at a single institution by 3 individual clinicians. Clinical evaluation was performed with exophthalmometry. Three clinicians from each clinical site assessed AGP with 3 different exophthalmometers and horizontal palpebral width using a ruler. Each physician made 3 separate measurements with each type of exophthalmometer not in succession. All photographic measurements were made at a single institution. AGP was measured from lateral photographs in which a standard marker was placed at the anterior lateral orbital rim. Horizontal and vertical palpebral fissure were measured from frontal photographs. Three trained readers measured 3 separate times not in succession. Exophthalmometry and photography method validity was assessed by agreement with CT (mean differences calculation, intraclass correlation coefficients [ICCs], Bland-Altman figures). Correlation between palpebral fissure and CT AGP was assessed with Pearson correlation. Intraclinician and interclinician reliability was evaluated using ICCs. RESULTS: Sixty-eight patients from 7 centers participated. CT mean AGP was 21.37 mm (15.96-28.90 mm) right and 21.22 mm (15.87-28.70 mm) left (ICC 0.996 and 0.995). Exophthalmometry AGP fell between 18 mm and 25 mm. Intraclinician agreement across exophthalmometers was ideal (ICC 0.948-0.983). Agreement between clinicians was greater than 0.85 for all upright exophthalmometry measurements. Photographic mean AGP was 20.47 mm (10.92-30.88 mm) right and 20.30 mm (8.61-28.72 mm) left. Intrareader and interreader agreement was ideal (ICC 0.991-0.989). All exophthalmometers' mean differences from CT ranged between -0.06 mm (±1.36 mm) and 0.54 mm (±1.61 mm); 95% confidence interval fell within 1 mm. Magnitude of AGP did not affect exophthalmometry validity. Oculus best estimated CT AGP but differences from other exophthalmometers were not clinically meaningful in upright measurements. Photographic AGP (right ICC = 0.575, left ICC = 0.355) and palpebral fissure do not agree with CT. CONCLUSIONS: Upright clinical exophthalmometry accurately estimates CT AGP in TED. AGP measurement was reliably reproduced by the same clinician and between clinicians at multiple institutions using the protocol in this study. These findings allow reliable measurement of AGP that will be of considerable value in future outcome studies.

Infectious Complication Following Midface Reconstruction With Calcified Triglyceride.

This case report describes an infectious complication related to the use of calcified triglyceride (Kryptonite Bone Cement) in post-traumatic midface reconstruction. Ultimately, the infected material required removal, and the facial deformity was repaired with subsequent procedures. The literature suggests that bone cement products should be used with caution when in contact with the paranasal sinuses.

C-Reactive Protein As a Marker for Initiating Steroid Treatment in Children With Orbital Cellulitis.

PURPOSE: To determine both the benefit of systemic steroids in pediatric patients with orbital cellulitis and to assess the usefulness of C-reactive protein (CRP) levels as a marker for starting steroids. METHODS: Prospective, comparative interventional study. Pediatric patients aged 1 to 18 years admitted to a tertiary care children's hospital with a diagnosis of orbital cellulitis from October 2012 to March 2014 were included in the study. All patients were treated with intravenous antibiotics, and patients with subperiosteal abscess who met previously published criteria for surgical decompression underwent combined transorbital drainage and/or endoscopic sinus surgery. CRP was measured daily as a biomarker of inflammation, and when below 4 mg/dl, patients were started on oral prednisone 1 mg/kg per day for 7 days. Patients whose families did not consent to steroid treatment served as the control group. Patients were followed after discharge until symptoms resolved and all medications were discontinued. RESULTS: Thirty-one children were diagnosed with orbital cellulitis during the study period. Of these 31 children, 24 received oral steroids (77%) and 7 did not (23%). There were 19 males and 5 females in the steroid group with an average age of 8.1 years, and 6 males and 1 female in the nonsteroid group with an average age of 7.1 years (p = 0.618). Thirteen patients (54%) in the steroid group and 2 patients (29%) in the nonsteroid group underwent sinus surgery with or without orbitotomy (p = 0.394). The average CRP at the onset of steroid treatment was 2.8 mg/dl (range: 0.5-4). Patients who received oral steroids were admitted for an average of 3.96 days. In comparison, patients who did not receive steroids were admitted for an average of 7.17 days (p < 0.05). Once CRP was ≤4 mg/dl, patients treated with steroids remained in the hospital for another 1.1 days, while patients who did not receive steroids remained hospitalized for another 4.9 days (p < 0.01). In the steroid group, 2 families reported increased hyperactivity in their children while on steroids. There was 1 case in each group of recurrence of symptoms after discharge from the hospital. Average follow-up time was 2.4 months in the steroid group and 2 months in the nonsteroid group (p = 0.996). At last visit, all patients returned to their baseline ophthalmic examination. There were no cases of vision loss or permanent ocular disability in either group. CONCLUSIONS: Our results give further evidence of the safety and benefit of systemic steroids in children with orbital cellulitis. Futhermore, this is the first study to suggest a standardized starting point (CRP ≤ 4 mg/dl) and dosing schedule (oral prednisone 1 mg/kg for 7 days) for children with orbital cellulitis. Patients who received systemic steroids after CRP dropped below 4 mg/dl were discharged from the hospital earlier than patients who did not receive systemic steroids.
