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.

Atypical presentations of orbital cellulitis caused by methicillin-resistant Staphylococcus aureus.

PURPOSE: To evaluate the epidemiologic and clinical features of orbital cellulitis caused by methicillin-resistant Staphylococcus aureus (MRSA). DESIGN: Multicenter, retrospective case series. PARTICIPANTS: Fifteen patients with culture-positive MRSA orbital cellulitis. METHODS: All recent cases of orbital cellulitis at several hospitals and surgical centers were reviewed, and cases with culture-positive MRSA from aspirates were identified. The data collected and analyzed retrospectively included patient demographics, medical history, presenting sign, imaging results, surgical procedure performed, surgical culture results, visual acuity at presentation and last follow-up, and duration of antibiotics. MAIN OUTCOME MEASURES: Presenting sign, radiographic evidence of paranasal sinus disease, radiographic evidence of multiple orbital abscesses, presence or absence of antecedent upper respiratory infection, and final visual acuity. RESULTS: Fifteen cases were identified. The mean patient age was 31.9 years (standard deviation, 24.2 years). Lid swelling was the presenting sign in 14 of 15 patients. No patients had a preceding upper respiratory infection, and only 1 patient had antecedent eyelid trauma. Only 3 of 15 patients had documented adjacent paranasal sinus disease on imaging. Lacrimal gland abscess or dacryoadenitis was the presenting finding in 5 of 15 patients. Multiple orbital abscesses were identified in 4 of 15 patients by computed tomography or magnetic resonance imaging. Fourteen of 15 cases required surgical intervention. Four of 15 cases had loss of visual acuity to light perception or worse. All 4 of these cases had a delay in referral for surgical intervention. CONCLUSIONS: In these 15 patients with MRSA orbital cellulitis, the typical clinical setting of orbital cellulitis was absent; chiefly, there was no identified antecedent upper respiratory illness, nor was there a preceding traumatic injury. Lid swelling in the absence of recent upper respiratory illness, lacrimal gland focus, multiple orbital abscesses, and lack of adjacent paranasal sinus disease may be predictive factors that suggest MRSA as the causative organism of orbital cellulitis.

Broad fascia fixation enhances frontalis suspension.

PURPOSE: To report the use of a modified frontalis suspension procedure for congenital ptosis patients with minimal to no levator function. METHODS: Retrospective, non-comparative case series of frontalis suspension by 2 surgeons over a 21-year period. RESULTS: Frontalis suspension with broad fascia fixation was performed on 48 eyelids of 25 patients. All patients had visual obscuration due to blepharoptosis with only 0 mm to 2 mm of measurable levator function. Age ranged from 3 to 13 years. Minimum length of follow-up was 6 months (range, 6-174 months). The palpebral fissure was increased in all patients, improving their head position and unmasking their visual axis in primary gaze. Postoperatively, all patients developed transient exposure symptoms. There were no migrations, extrusions, infections, or granulomas. All patients achieved a satisfactory postoperative result based on eyelid position, function, and contour. CONCLUSIONS: This modified frontalis suspension procedure maximizes frontalis muscle recruitment, creating powerful eyelid elevation with stable effect over time. The technique minimizes other procedures' pitfalls and advances in cosmesis are achieved with enhanced eyelid crease formation and adjustable eyelid contour.

Hyaluronic acid gel (Restylane) filler for facial rhytids: lessons learned from American Society of Ophthalmic Plastic and Reconstructive Surgery member treatment of 286 patients.

PURPOSE: To review injection techniques and patient satisfaction with injection of Restylane in various facial areas by American Society of Ophthalmic Plastic and Reconstructive Surgery members. METHODS: Data from 286 patients treated with Restylane in nine American Society of Ophthalmic Plastic and Reconstructive Surgery practices were abstracted to a spreadsheet for analysis. RESULTS: Nine practices performed Restylane injections for 8.8 months on average (range, 2 to 28 months). Average practice volume per patient was 1.2 ml (range, 0.7 to 2.1 ml). Nine of nine practices injected the nasolabial and melolabial folds, 9 of 9 practices injected the lips, and 6 of 9 injected the glabella. Only 2 of 9 practices injected other fillers concurrently. Botox was injected concurrently by 8 of 9 practices. On a scale of 1 to 10, physicians rated average patient discomfort during Restylane injection 4.6 with topical anesthesia and 2.1 with injectable lidocaine, with or without topical anesthesia. The end point for injection was determined by visual cues, volume of injection, extrusion of the product, and palpation. "Problematic" complications, including bruising, swelling, bumpiness, and redness each had an incidence of 5% or less. Patient satisfaction on a scale of 1 to 10 had an average rating of 8.1, compared with that of Botox injection (8.9), upper blepharoplasty (8.9), and collagen injection (6.6). The source of Restylane patients was estimated to be existing Botox patients (45%); existing non-Botox patients (18%); word of mouth (14%); and new patients for other services (13%). CONCLUSIONS: Injection techniques, volume, end points, and anesthesia vary for different facial areas and between practices. Patients experience mild to moderate injection discomfort that is lessened with injectable lidocaine. Self-limited problems occur in about 5% of patients. Physician-determined patient satisfaction is perceived to be higher than that of collagen injection but slightly lower than that of botulinum toxin injection. The major source of Restylane patients was from existing practice patients, especially botulinum toxin patients.

The smooth surface tunnel porous polyethylene enucleation implant.

BACKGROUND AND OBJECTIVE: To describe early clinical results with the porous polyethylene smooth surface tunnel (SST) enucleation implant. PATIENTS AND METHODS: Uncontrolled, prospective interventional case series of patients undergoing enucleation with placement of the SST implant. This implant consists of a porous polyethylene sphere with a smooth anterior surface containing pre-drilled tunnels to facilitate direct suturing of the rectus muscles to the implant without use of an implant wrap. Postoperatively, socket healing was assessed, and prosthesis and socket motility were evaluated by the surgeon using an ordinal scale (0 = no motility to 4 = excellent motility). RESULTS: Thirty patients received the SST implant, with a mean follow-up of more than 23 months. Two cases of exposure occurred and were managed surgically without the need for explantation. Mean socket motility was 3.1 on a 0 to 4 ordinal scale, with mean prosthesis motility of 2.8. CONCLUSION: The SST implant provides satisfactory socket motility and is generally well tolerated in the anophthalmic socket without the need for wrapping material.

Use of bioglass for orbital volume augmentation in enophthalmos: a rabbit model (oryctolagus cuniculus).

PURPOSE: To investigate the clinical and histologic response of Novabone-C/M as an osteoproductive alloplastic implant for volume augmentation in the orbit in the treatment of enophthalmos and to compare its outcome alone versus its use in combination with autogenous bone or Medpor granules. METHODS: Novabone-C/M, a bioactive silicone glass material, was implanted in the subperiosteal space of the left orbit of 12 New Zealand White rabbits. The animals were divided into 3 groups, each with 4 animals, based on the material implanted in the orbit: group 1, Novabone alone; group 2, Novabone plus Medpor granules; and group 3, Novabone plus autogenous bone fragments. All rabbits were studied clinically, radiographically, and histologically at 1-, 3-, and 6-month intervals. Animals underwent preoperative and postoperative computed tomography (CT) with 3-dimensional reconstruction, proptosis measurements, and volumetric analysis. Orbit specimens were studied histologically with mineralized bone stain (MIBS) to look for bone formation, reactivity, infection, implant resorption, and migration. RESULTS: There were no signs of significant inflammation or infection. Subcutaneous migration of the implant was seen radiographically but not clinically in groups 1 and 3. Induced proptosis averaged 2.5 mm (at 1 month) and showed regression in all groups over a 6-month period but was not statistically significant. Implant volume was markedly reduced in all groups, averaging 69% in group 1, 37% in group 2, and 59% in group 3 at 6 months. New bone formation and bone remodeling was present in all 3 groups at 3 months and only in group 2 at 6 months. The rate and amount of implant remodeling and bone formation was greatest in the Novabone/Medpor group (group 2). CONCLUSIONS: Bioglass particulate is biocompatible, easy to use in the orbit, and stimulates bone growth. Bioglass is associated with volume loss and migration over 6 months and may not provide adequate volume augmentation in the orbit when used alone for the treatment of enophthalmos. The duration and amount of bone formation may be enhanced when Novabone is used in conjunction with Medpor.

Orbital rhabdomyosarcoma metastatic to the contralateral orbit: a case report.

OBJECTIVE: To report a rare presentation of metastatic orbital rhabdomyosarcoma and the corresponding findings on magnetic resonance imaging (MRI). DESIGN: Interventional case report. RESULTS: A 29-year-old white man was diagnosed with rhabdomyosarcoma of the left sinus and orbit for which he was treated with chemotherapy and radiation. Eighteen months after diagnosis, he returned with subacute right eye pain and dysmotility of his extraocular muscles. MRI revealed solitary enlargement of the right medial rectus muscle, and thyroidopathy was suspected. Over the next 2 months, symptoms progressed, and proptosis developed. MRI showed infiltration of seven extraocular muscles. A biopsy of right orbital tissues and the right medial rectus muscle was performed. Special tissue typing confirmed metastatic alveolar rhabdomyosarcoma. The patient underwent palliative radiation therapy and chemotherapy, but he ultimately died of disseminated disease. CONCLUSIONS: Rhabdomyosarcoma can rarely metastasize to the extraocular muscles. Earlier recognition of orbital metastasis through radiographic and biopsy findings, along with prompt and aggressive treatment, may prevent fulminant spread of rhabdomyosarcoma.
