Oral Sedation Anesthesia Protocol for In-Office Oculoplastic Surgery.

PURPOSE: To present an oral anesthesia protocol for in-office oculoplastic surgery and to compare safety outcomes and patient and physician experiences to ambulatory surgery center (ASC)-based surgery with intravenous sedation or general anesthesia. METHODS: A prospective study was performed on consecutive patients undergoing surgery at an oculofacial plastic surgery practice. Surgery was performed in an in-office setting using our standardized oral sedation protocol or at an ASC with intravenous sedation or general anesthesia. Preoperative and postoperative surveys were conducted by patients and physicians to compare surgical experience, safety, and efficacy of our oral sedation protocol for in-office surgery in the ASC setting. RESULTS: Two hundred and fifty-three patients (167 in-office and 86 at ASC) underwent surgery between March and November 2022. There was no significant difference in how patients or physicians rated their experience between the 2 locations. A significantly higher proportion of ASC patients would have rather had surgery in-office (34.9% vs. 19.2%; p = 0.006). A significantly higher number of physicians in the office setting would have rather performed surgery at the ASC than the reverse (12.7% vs. 2.3%, respectfully; p = 0.007). There were no safety complications reported in either setting. CONCLUSIONS: Within our patient cohort, the presented oral sedation protocol provided safe and effective anesthesia for in-office oculoplastic surgery that is comparable to an ASC.

What is in a Name? It is Time to Retire the Term "Asian Blepharoplasty".

PURPOSE: This perspective explores the term "Asian blepharoplasty" and its socioemotional meaning to some patients. METHODS: N/A. RESULTS: Words have power. The term "Asian blepharoplasty" makes some patients uncomfortable. To our knowledge, it is the only medical descriptor that uses race. CONCLUSIONS: The use of the term "Asian Blepharoplasty" may unwittingly make patients uncomfortable and pathologize Asian features. Therefore, we suggest replacing the term "Asian Blepharoplasty" with "Double Eyelid Surgery." For the subset of procedures which do not include the creation of an eyelid crease, "Blepharoplasty" is appropriate.

Microbiology and Biofilm Trends of Silicone Lacrimal Implants: Comparing Infected Versus Routinely Removed Stents.

PURPOSE: To investigate the pathogens and biofilms responsible for clinically significant infection of silicone stents implanted within the lacrimal system. METHODS: Retrospective review of culture results and patient demographics for all silicone lacrimal stents removed early for clinically significant infection and sent to the Bascom Palmer Microbiology Laboratory through the end of year 2010. As a control, routinely removed, clinically noninfected stents from the same institution were prospectively sent for culture over a 6-month period. Four clinically infected and 6 clinically noninfected stents showing mucus within the lumen at removal were sent for scanning electron microscopy. Images were randomized and graded by a microbiologist for the presence of organisms, matrix deposits, organisms within matrix, and overall impression of significant biofilm formation. RESULTS: Nineteen stents were included in the study; 100% of clinically infected (n = 10) and noninfected (n = 9) stents were culture positive. Culture positivity for nontuberculous mycobacterium was found in 90% of infected stents and none of the noninfected stents (p < 0.001). Of infected stents, 50% grew Gram-positive organisms compared with 89% of noninfected stents (p = 0.07). Fifty percent of infected versus 67% of noninfected stents were culture positive for Gram-negative organisms (p = 0.46). Electron microscopy of stents revealed organisms consistent with culture results (size, shape) in planktonic and biofilm form. Masked observer image grading revealed a statistically significant higher amount of organism and biofilm on infected versus noninfected specimen. CONCLUSION: Nontuberculous mycobacteria comprise the primary pathogens responsible for clinically significant infection of silicone stents in the lacrimal system in South Florida. Robust biofilm production by this organism likely plays a role in pathogenesis. Further research into biofilm-related lacrimal implant infection may aid in the development of useful prevention and treatment strategies.

Orbital Tumors Excision without Bony Marginotomy under Local and General Anesthesia.

To present our experience of removing middle to deep orbital tumors using a combination of minimally invasive soft tissue approaches, sometimes under local anesthesia. Methods. In this retrospective case series, 30 patients (13 males and 17 females) underwent tumor removal through eyelid crease (17 eyes), conjunctival (nine eyes), lateral canthal (two eyes), and transcaruncular (two eyes) approaches. All tumors were located in the posterior half of the orbit. Six cases were removed under monitored anesthesia care with local block, and 24 were under general anesthesia. Results. The median (range) age and follow-up duration were 48.5 (31-87) years old and 24.5 (4-375) weeks, respectively. Visual acuity and ocular motility showed improvement or no significant change in all but one patient at the latest followup. Confirmed pathologies revealed cavernous hemangioma (15 cases), pleomorphic adenoma (5 cases), solitary fibrous tumor (4 cases), neurofibroma (2 cases), schwannoma (2 cases), and orbital varix (1 case). None of the patients experienced recurrence. Conclusions. Creating a bony marginotomy increases intraoperative exposure of the deep orbit but adds substantial time and morbidity. Benign orbital tumors can often be removed safely through small soft-tissue incisions, without bone removal and under local anesthesia.

On-Q pump for pain control after orbital implant surgery.

PURPOSE: To introduce an elastomeric continuous infusion pump for pain control after outpatient orbital implant surgery. METHODS: Retrospective, noncomparative consecutive case series of all patients undergoing enucleation, evisceration, or secondary orbital implantation using the On-Q pain system between August 2004 and January 2006. Postoperative pain score, need for narcotics, and adverse events were recorded. The On-Q catheter is inserted intraoperatively through the lateral lower eyelid into the muscle cone under direct visualization, prior to the orbital implant placement. The On-Q system continually infuses anesthesia (bupivacaine) to the retrobulbar site for 5 days. RESULTS: Among 20 patients, mean postoperative period pain score, with On-Q in place, was 1.3 (scale of 0 to 10). Nine patients (45%) did not need any adjunctive oral narcotics. Two patients experienced postoperative nausea. One catheter connector leaked, thereby decreasing delivery of retrobulbar anesthetic resulting a pain level of 6, the highest level in the study. There were no postoperative infections. No systemic toxic effects from bupivacaine were observed clinically. CONCLUSION: The On-Q pain pump is widely available, low cost, and requires minimal patient manipulation for the use in orbital implant surgery. The device was safe and appeared to minimize postoperative pain in the authors' case series.

PROSE scleral lens: a novel aid for staged eyelid reconstruction.

A 50-year-old man presented with a papillomatous tarsoconjunctival tumor involving the medial two-thirds of the left upper eyelid. Office biopsy revealed papillary squamous cell carcinoma (SCCA). Rapid tumor growth with caruncular and forniceal conjunctival involvement continued, despite a trial of weekly interferon-α2b intralesional injection therapy. Surgical excision with clear margins resulted in a large upper eyelid defect. The suspicion for recurrence remained, given the aggressive nature of the tumor. A temporary prosthetic replacement of the ocular surface ecosystem (PROSE) scleral lens was fit for preservation of the ocular surface and visual function during a 1-month observation period. No evidence of recurrence was noted, and the eyelid defect was successfully reconstructed with a Cutler-Beard procedure. Local disease was controlled; unfortunately, metastatic disease was found in the ipsilateral parotid gland 1 year later. Aggressive surgical removal is recommended in interferon-α2b nonresponsive SCCA tumors. The PROSE scleral contact lens may serve as a useful adjunct for the maintenance of a healthy ocular surface and visual function during delayed eyelid defect repair.

Microbiologic trends and biofilm growth on explanted periorbital biomaterials: a 30-year review.

PURPOSE: To investigate microbiologic trends and role of biofilm on periorbital biomaterials surgically explanted for recalcitrant infection. METHODS: A search of the Bascom Palmer Eye Institute, University of Miami Miller School of Medicine microbiology laboratory electronic database was conducted from 1980 to 2010. Culture results were analyzed from submitted periorbital biomaterials explanted for nonresolving infections or exposure. Random select samples cultured during the study were sent for electron microscopy. RESULTS: Twenty-one explanted biomaterials were identified from 18 patients. Five orbital plate implants included 2 made of nylon, 1 of porous polyethylene, 1 of silicone, and 1 metallic. Of 4 anophthalmic socket sphere implants, 2 were silicone, 1 was porous polyethylene, and 1 was poly-2-hydroxyethyl methacrylate. Lacrimal intubation devices included 10 silicone stents and 2 pyrex glass Jones tubes. All biomaterials were culture positive with 40 total isolates identified. The most common organisms overall were Mycobacterium chelonae (N = 9), Staphylococcus aureus (N = 8), and Pseudomonas aeruginosa (N = 3). One hundred percent of orbital spheres had Gram-positive organisms, 90% of lacrimal silicone stents grew atypical mycobacterium, and 60% of orbital plates were culture positive for yeast species. Mixed organism growth was documented on 58% of the specimens. Ten of 12 implants (83%) examined with electron microscopy exhibited organisms encased in glycocalyx, suggestive of biofilm. CONCLUSIONS: A diverse array of microorganisms can colonize biomaterials implanted within the orbit and lacrimal drainage system. The authors' study showed that the majority of infected periocular and orbital alloplastic implants display biofilm when studied with electron microscopy (83%). The cultured organism type depended on the implant location and composition. Most infected silicone lacrimal stents grew atypical mycobacterium, whereas infected orbital fracture repair plates demonstrated yeast species. Biofilms are known to be antibiotic resistant, explaining the need to explant most infected alloplastic implants. Further research concerning treatment of biofilms may prevent explantation and improve surgical outcomes.

The modified fasanella-servat procedure: description and quantified analysis.

PURPOSE: To describe a modified Fasanella-Servat procedure and nomogram for the correction of minimal amounts of ptosis. METHODS: Retrospective review of this modified Fasanella-Servat procedure was performed on 118 eyelids in 86 consecutive patients over 2, 4-year periods by 1 surgeon (S.C.D.). The amount of tarsectomy was based on the amount of ptosis. RESULTS: Mean pre- and postoperative margin-to-reflex distance 1 were +0.7 mm and +2.4mm, respectively. One hundred and twelve eyelids (95%) had satisfactory results with postoperative margin-to-reflex distance 1 ≥ 1.5 mm. Eyelid symmetry was achieved in 92% of eyelids to within 0.5 mm. There was no incidence of overcorrection, tarsal buckling, or corneal abrasion. One eyelid had a contour deficit. Tarsectomy amount ranged from 2 mm to 5 mm. Average amount of tarsectomy to eyelid elevation was 2.4:1. CONCLUSIONS: The modified Fasanella-Servat procedure is technically easy, time-efficient, and has a low complication rate for the treatment of minimal blepharoptosis (< 2.5 mm) with good levator function and negative phenylephrine test. In the authors' hands, the ratio of tarsectomy to eyelid elevation is approximately 2:1. In addition to other techniques such as levator advancement and Müller's muscle conjunctival resection, the modified Fasanella-Servat technique is a useful adjunct to the modern ptosis surgeon's armamentarium.

An anatomically based approach to intralesional corticosteroid injection for eyelid capillary hemangiomas.

BACKGROUND AND OBJECTIVE: To describe a corticosteroid injection technique for eyelid capillary hemangiomas that minimizes the risk of a central retinal artery occlusion and is based on anatomic, physiologic, and pharmacologic rationales. PATIENTS AND METHODS: In this retrospective, non-comparative, interventional case series, the medical records of 50 eyes of 50 patients over a 10-year period were reviewed for retinal complications associated with the described injection technique. RESULTS: Ophthalmoscopy showed no retinal complications in the 50 eyes treated with this injection technique. CONCLUSION: The risk of central retinal artery occlusion from retrograde embolization can be minimized by using an anatomically based injection technique that prevents canalization of an artery and avoids injection pressures exceeding the mean systemic arterial pressure.

Recalcitrant epithelial ingrowth in patients with compromised eyelid function.

PURPOSE: To report recalcitrant unilateral epithelial ingrowth in two patients with ipsilateral weak eyelid closure. METHODS: Two patients with weak eyelid closure who underwent simultaneous, uncomplicated LASIK developed unilateral epithelial ingrowth. RESULTS: Eight months postoperatively, one patient presented with right-sided epithelial ingrowth. One month after removal, more extensive epithelial ingrowth was noted and removed, and the flap gutters were sealed with fibrin adhesive. Epithelial ingrowth recurred 1 week later. The epithelial ingrowth was removed and the flap was secured with concurrent placement of radial 10-0 nylon sutures. No further epithelial ingrowth recurred. In the second patient, epithelial ingrowth was noted in the left eye 4 months postoperatively. Eight months later, the ingrowth was removed with subsequent recurrence in 2 weeks. CONCLUSIONS: Weak eyelid closure may be a predisposing factor to poor flap adhesion and epithelial ingrowth. Close attention to lid function may be of importance in deciding between LASIK and photorefractive keratectomy, particularly in patients with other risk factors for epithelial ingrowth.

The hydrogel lacrimal stent for dacryocystorhinostomy: preliminary experience.

PURPOSE: To present the results of dacryocystorhinostomy with the use of a newly designed hydrogel lacrimal stent for repair of acquired nasolacrimal duct obstruction. METHODS: Noncomparative interventional case series. Twenty-three cases of acquired nasolacrimal duct obstruction confirmed by probing and irrigation underwent dacryocystorhinostomy using the hydrogel lacrimal stent. Tearing symptoms, functional endoscopic dye test, and anatomic appearance of ostia were noted at follow-up. RESULTS: Five of 23 ostia closed during the postoperative period (1-3 months), translating to a late success rate of 78.3%. The 5 failed cases were treated successfully with ostium revision, 1 case requiring 2 revisions. All patients had endoscopic follow-up with a minimum follow-up of 6 months after stent removal. In the successful cases we noted a large, quiet ostium with good separation of the nasal septum and middle turbinate. Eleven cases (47.8%) had history of previously failed dacryocystorhinostomy surgery, chronic sinusitis, deviated septum, or maxillofacial surgery. There were no complications or reports of unusual pain or symptoms associated with the stent itself. CONCLUSIONS: Early experience suggests the hydrogel lacrimal stent is a well-tolerated, effective tool for dacryocystorhinostomy surgery after acquired nasolacrimal duct obstruction. The device may serve as a useful surgical tool by holding open the ostium, maintaining apposition of the mucosal edges, and decreasing the incidence of nasal adhesions.

Comparison of the responsiveness of the SF-36 and WOMAC in patients undergoing total hip arthroplasty.

This study examines the responsiveness of the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and Short Form-36 (SF-36) in patients undergoing total hip arthroplasty. Eighty-nine patients completed the WOMAC and SF-36 preoperatively and postoperatively. Standardized response means (SRMs) and effect sizes (ES) were used to measure responsiveness. Mean follow-up was 17 months. The SRMs for the WOMAC ranged from -0.93 to -1.49, and the ES ranged from -1.02 to -1.53. The SRMs for the SF-36 ranged from 0.22 to 1.64, and the ES ranged from 0.20 to 1.97. The highest values occurred with the physical functioning, bodily pain, and Physical Component Summary Scales. This study demonstrates a similar level of responsiveness of the WOMAC and several components of the SF-36. This suggests that the isolated use of the SF-36 may be adequate to monitor outcomes after total hip arthroplasty. There may still be a role for the WOMAC when comparing outcomes of specific designs or techniques of total hip arthroplasty.

Evaluation of the validity of the Foot Function Index in measuring outcomes in patients with foot and ankle disorders.

BACKGROUND: There is uncertainty regarding which outcomes tools should be used to report the results of treatment for patients with foot and ankle disorders. This study evaluates the validity of the Foot Function Index (FFI) by examining its level of correlation to the Medical Outcomes Study Short Form-36 (SF-36). The SF-36 is an extensively validated outcomes tool that has been used as a benchmark in examining the validity of several orthopaedic outcomes tools. METHODS: Seventy-three patients were recruited at a tertiary referral foot and ankle practice. Patients completed packets which included informed consent forms, the FFI, and the SF-36 questionnaires. The questionnaires were scored and Pearson correlation coefficients were determined between the three domains of the FFI and the eight SF-36 sub-scales, as well as the two SF-36 summary scales. RESULTS: Sixty-nine patients completed an adequate number of items to be included in the study. The mean age of the patient sample was 46 (range 16 to 82) years and 44 were women (64%). Twenty-one patients (30%) had conditions affecting the forefoot, while 48 patients (70%) had conditions affecting the ankle or hindfoot. All three FFI domains had moderate to high levels of correlation to many of the SF-36 scales. The Disability domain of the FFI had the most consistent level of correlation to the SF-36 with Pearson coefficients in the range of -0.23 to -0.69. The Activity Limitation (r=-0.28 to -0.64) and Pain domains (r=-0.10 to -0.61) also demonstrated moderate levels of correlation to several of the SF-36 scales. CONCLUSIONS: The consistently moderate to high levels of correlation of the FFI to the SF-36 seen in this study support the FFI as a valid measure of health status. This suggests that the FFI is a reasonable method to monitor patient outcomes. Future studies should focus on determining if the FFI improves responsiveness to clinical change when used in combination with generic instruments like the SF-36.
