Dry Eye Symptoms and Chemosis Following Blepharoplasty: A 10-Year Retrospective Review of 892 Cases in a Single-Surgeon Series

OBJECTIVES To determine the incidence of and risk factors associated with dry eye symptoms (DES) and chemosis following upper or lower blepharoplasty. To examine the outcomes among long-term blepharoplasty data to better understand the incidence of and risk factors associated with dry eye symptoms (DES) and chemosis, to evaluate the known risk factors for DES in the general population, and to analyze intraoperative procedures (such as forehead-lift, midface-lift, canthopexy, and canthoplasty) to determine their effects on DES and chemosis. METHODS A retrospective medical record review was performed among all the cases of upper or lower blepharoplasty performed by the senior author during a 10-year period (January 1999 through December 2009). A self-reported dry eye questionnaire was used to collect baseline and follow-up data. Patients with incomplete medical records, multiple (>1) revision procedures, less than 3 weeks of postoperative follow-up data, or a history of Sjögren syndrome, severe thyroid eye disease, histoplasmosis ocular infection, periocular trauma causing eyelid malposition, or radiotherapy for nasopharyngeal cancer were excluded from the study. Binary logistic regression analyses were performed to analyze the relationship between 13 preoperative and anatomical variables and DES or chemosis. χ2 Tests were performed to analyze the relationship between intraoperative risk factors and DES or chemosis. RESULTS In total, 892 cases met the study inclusion criteria. Dry eye symptoms and chemosis following blepharoplasty were reported in 26.5% and 26.3% of patients, respectively. The incidences of DES and chemosis were significantly higher in patients who underwent concurrent upper and lower blepharoplasty (P < .001) and in patients who underwent skin-muscle flap blepharoplasty (P = .001). Hormone therapy use and preoperative scleral show were associated with DES after blepharoplasty (P < .05). Male sex, preoperative eyelid laxity, and preoperative DES were associated with an increased incidence of chemosis following blepharoplasty (P < .05). Intraoperative canthopexy significantly increased the risk for developing chemosis (P = .009), and postoperative lagophthalmos significantly increased the risk for DES following blepharoplasty (P < .001). CONCLUSIONS Dry eye symptoms and chemosis are common following blepharoplasty, and the risk for developing these conditions may increase with intraoperative canthopexy, postoperative temporary lagophthalmos, concurrent upper and lower blepharoplasty, and transcutaneous approaches violating the orbicularis oculi muscle. Patients with a preoperative history of DES, eyelid laxity, scleral show, or hormone therapy use may be at greater risk for developing dry eyes or chemosis following surgery.

Microporous polysaccharide hemospheres do not increase synechiae after sinus surgery: randomized controlled study.

Background Many surgeons use absorbable packing materials after endoscopic sinus surgery (ESS). Despite their popularity, some of these agents have been shown to contribute to synechiae formation. Microporous polysaccharide hemospheres (MPH) is a plant-based hemostatic powder that does not interfere with regenerating sinus mucosa in the animal model. The goal of this study was to examine the impact of MPH on healing and synechiae formation after ESS in human subjects. Methods A prospective, randomized, controlled, double-blind study was performed. Forty consenting adult patients with chronic sinusitis requiring symmetric ESS were randomized to receive MPH unilaterally at the conclusion of surgery. The opposite side was untreated. Standard postoperative care was performed bilaterally. Outcomes measured included blinded observer ratings for synechiae formation, edema, and infection. Each side was examined endoscopically and scored at postoperative days 7, 14, and 30. Results Twenty men and 20 women with an average age of 48.2 years were included. There were no complications and all patients were discharged home the same day. There was no significant difference in synechiae formation at any point postoperatively. The rate of synechiae formation was determined to be 10% (4/40) on the MPH-treated side versus 7.5% (3/40) on the untreated side (p = 0.7639). In addition, there were no significant differences observed in edema (p = 0.7480) or infection (p = 0.5533). Conclusion The use of MPH after sinus surgery does not increase synechiae formation and does not appear to deleteriously affect the healing of postoperative sinus cavities.

Influence of Residual Tumor Volume and Radiation Dose Coverage in Outcomes for Clival Chordoma

PURPOSE The purpose of this study was to evaluate factors associated with tumor control in clival chordomas. METHODS AND MATERIALS A retrospective review of 39 patients treated with surgery and proton therapy for clival chordomas between 2004 and 2014 was performed. The median prescribed dose was 77.4 Gy (relative biological effectiveness [RBE]); range was 70.2-79.2 Gy (RBE). Minimum and median doses to gross tumor volume (GTV), radiation dose received by 1 cm(3) of GTV (D1cm(3)), and the equivalent uniform dose were calculated. Receiver operating characteristics curves evaluated the predictive sensitivity and specificity for local failure of potential cutpoint values for GTV and D1cm(3). RESULTS After a median follow-up of 51 months, the 5-year estimate of local control (LC) was 69.6% (95% confidence interval [CI] 50.0%-89.2%), and overall survival (OS) was 81.4% (95% CI: 65.3%-97.5%). Tumor histology, GTV at the time of radiation, and prescribed radiation dose were significantly associated with local control on multivariate analysis, whereas D1cm(3) was associated with overall survival. Compared to those patients whose conditions remained controlled, patients experiencing tumor failure had statistically significant larger GTVs and lower D1cm(3), and prescribed and median doses to GTV. A subset of 21 patients with GTV of ≤20 cm(3) and D1cm(3) of >67 Gy (RBE) had a median follow-up of 47 months. The 5-year estimate of local control in this subset was 81.1% (95% CI: 61.7%-100%; P=.004, overall comparison by GTV ≤20 cm(3) stratified by D1cm(3)). A D1cm(3) of 74.5 Gy (RBE) had 80% sensitivity for local control and 60% specificity, whereas a GTV of 9.3 cm(3) had 80% sensitivity for local control and 66.7% specificity. CONCLUSIONS Local control of clival chordomas was associated with both smaller size of residual tumor and more complete high-dose coverage of residual tumor. Multidisciplinary care should seek maximal safe surgical resection, particularly to facilitate delivery of high-dose radiation therapy in proximity to critical structures. A D1cm(3) ≥74.5 Gy (RBE) represents a proposed treatment planning objective.

Free graft techniques in skull base reconstruction.

Over the last 20-30 years, the management of anterior skull base defects, CSF leaks and encephaloceles has shifted towards endoscopic, minimally invasive approaches. Whether their etiology is spontaneous or traumatic, the large majority of these lesions can be repaired with free mucosal grafts. Such grafts may be readily harvested from the nasal septum or turbinates and applied as either a single layer reconstruction for small leaks or as a multilayer reconstruction for larger defects. The accessibility, ease of placement, and high take rate associated with free mucosal grafts makes them a wise and popular choice for reconstruction of many skull base defects.

Indications for Surgery in Refractory Rhinitis

Medical treatment of chronic rhinitis is successful in a majority of patients, but there is a still large population of patients who fail medical therapy. Surgical treatment for patients with severe persistent allergic rhinitis is not a new solution, but recent advancements in technology and surgical technique have made surgery safer and more effective. There is no gold standard of treatment in patients with refractory rhinitis, and surgeons may select a variety of procedures and techniques based on a patient’s anatomy, severity of disease, and comorbidities. Unfortunately, there are currently few large prospective, randomized controlled trials evaluating surgical treatments, and no study to date has compared immunotherapy to surgical intervention. Therefore, there is no hard and fast rule as to when to pursue surgical intervention after initial medical therapy has failed.

Outcomes of Sinonasal Squamous Cell Carcinoma with and without Association of Inverted Papilloma: A Multi-Institutional Analysis

Introduction Sinonasal squamous cell carcinoma (SCC) accounts for <1% of all malignancies but represents 70% of sinonasal cancer. Up to 10% of SCCs are associated with inverted papilloma (IPSCC). Studies that compare patients, treatment, and outcomes of SCC and IPSCC are absent in the literature. Methods A retrospective review of patients with SCC and those with IPSCC at Cleveland Clinic and Indiana University from 1995 to 2015. The records were analyzed for demographics, tumor characteristics, treatment, and outcomes. Results The study comprised 117 patients with SCC, of whom, 29 had IPSCC. The mean age at diagnosis was similar: 63 and 64 years for patients with SCC and patients with IPSCC, respectively; with female patients representing 36% and 34%, respectively (p > 0.99). Smokers represented 64% of the patients with SCC and 55% of patients with IPSCC (p = 0.3); excessive alcohol intake was noted in 16% of the patients with SCC and 21% of the patients with IPSCC (p = 0.56). The maxillary sinus was most commonly involved, followed by the nasal cavity (51% versus 35% SCC, 45% versus 38% IPSCC). Frontal ethmoid and sphenoid sinuses contained primary tumors only in patients with SCC. Upfront treatment was surgery in 84% of patients with SCC and 97% of patients with IPSCC (p = 0.18); 68 and 55% received radiation, respectively, and 25 and 21% received chemotherapy, respectively. Overall survival averaged 5.5 and 3.4 years for patients with SCC and patients with IPSCC, respectively (p = 0.12); disease-free survival was 4.8 and 2.9 years, respectively (p = 0.18). Nodal metastasis was more likely in patients with SCC (18 versus 0%; p = 0.02). When divided into high- and low-stage disease: more common nodal metastases were demonstrated in high-stage SCC than in low-stage disease (p = 0.03). Overall survival was decreased between high- and low-grade disease but not when subdivided between SCC and IPSCC. Conclusion Although SCC with and without IP association are considered different diseases, their demographics and outcomes seem similar. Nodal metastasis was noted to be higher in the SCC cohort, which may indicate different tumor biology. Further study is warranted.

Endoscopic endonasal transplanum transtuberculum resection of a large solid choroid plexus papilloma of the third ventricle

Choroid plexus papilloma (CPP) is a highly vascular solid or mixed solid-cystic tumor. Previously described resection techniques for the more common solid CPP in the third ventricle have all been through the transcranial route. The authors review the literature and describe a patient who, to their knowledge, is the first successful resection of a large, completely solid CPP of the third ventricle through an entirely endoscopic, extended transphenoidal approach. Using modern neuroendoscopic methods and closure techniques, a gross total resection was accomplished and a successful closure without postoperative cerebrospinal fluid leak was achieved despite the presence of preoperative hydrocephalus. For appropriately selected lesions, an extended endonasal skull base resection can be performed successfully for vascular tumors despite the presence of preoperative hydrocephalus.

Effects of simultaneous speech and sign on infants' attention to spoken language†‡§

To examine the hypothesis that infants receiving a degraded auditory signal have more difficulty segmenting words from fluent speech if familiarized with the words presented in both speech and sign compared to familiarization with the words presented in speech only.

Managing Voice Impairment After Injection Laryngoplasty

To date, there is a paucity of literature on the management of suboptimal voice outcomes after injection laryngoplasty. We present three cases of worsened voice quality and impaired mucosal waveform propagation on videostroboscopy after calcium hydroxylapatite (CaHA) injection. The first was found to have superficial deposits of CaHA in Reinkes space. The second case appeared to have overaugmentation of the vocal folds. The third case had atrophic vocal folds, and despite having a deep CaHA injection (within the thyroarytenoid muscles), the injected vocal folds had diminished mucosal waveform amplitude, which was likely because of poor pulmonary function. In summary, there can be multiple reasons for suboptimal voice outcomes after CaHA. Clinician awareness and intraoperative recognition of improper CaHA injection/overinjection can help prevent most negative outcomes.
