RESUMO
PURPOSE: To describe a novel surgical technique for implanting eyelid weights via a sutureless transconjunctival approach. In comparison to the traditional supratarsal crease approach, this technique does not involve any external incisions or suture placement. The procedure can reduce surgical time and complications associated with the traditional external approach. METHODS: This case series includes 13 patients who underwent eyelid weight placement via the transconjunctival approach for paralytic lagophthalmos secondary to facial nerve paralysis (12 patients had unilateral paralysis and 1 patient had bilateral) with a total of 14 eyelid weights placed. The procedures were performed at an outpatient office-based surgical center. All procedures were performed or supervised by the same surgeon. Patients were followed for an average 6-month postoperative period for postoperative complications. RESULTS: The sutureless transconjunctival approach to eyelid weight insertion was successful in achieving the desired functional and aesthetic outcomes. Patients undergoing this technique avoided the discomfort of postoperative suture removal. All patients achieved comparable outcomes postoperatively. There were no complications reported across the 13 patients throughout the 6-month postoperative period. CONCLUSIONS: This case series demonstrates that the transconjunctival approach for metal eyelid weight insertion is practical, relatively easy to perform, and associated with functional outcomes that are comparable to those achieved with the traditional approach, however, without external incision or placement of sutures.

Eyelid malposition is a challenging problem faced by surgeons. Given the delicate nature of the eyelid and its complex anatomy, eyelid repair requires both a comprehensive understanding of eyelid anatomy along with thorough presurgical planning and surgical execution. A wide range of options is available for eyelid reconstruction but the location and extent of the deformity often dictate the type of repair. This article is a review of commonly encountered forms of eyelid malposition. Relevant reconstructive techniques and current evidence-based methods of reconstruction are discussed in detail. Anatomical considerations, the nature of specific defects, pearls of preoperative evaluation, and the reconstructive options available to the facial plastic and oculoplastic surgeon are outlined. Topics discussed include ectropion, entropion, eyelid retraction, and blepharoptosis.
RESUMO
IMPORTANCE: Transoral robotic surgery has revolutionized the practice of head and neck surgery over the past decade, with indications now expanding to include laryngeal pathology. Although laryngeal chondrosarcoma is a rare entity, trends in otolaryngology literature suggest that it can frequently be managed with conservative approaches. We hope to inspire other head and neck surgeons to consider transoral robotic surgery for the treatment of such tumors so that outcomes data can be collected and studied. OBSERVATION: An 87-year-old male presented with a left-sided supraglottic mass that was found incidentally on imaging performed for an unrelated reason. Flexible fiberoptic laryngoscopy revealed a cystic-appearing supraglottic mass with near complete obstruction of the glottis airway. Internal review of the imaging demonstrated a 3.5 by 2.3 by 2.8â¯cm centrally hypodense lesion with a rim of calcification in the left paraglottic space, with resultant narrowing of the laryngeal airway. INTERVENTION: The patient underwent awake tracheostomy and transoral robotic subtotal resection of the mass using the Da Vinci surgical system (Intuitive Surgical Inc., Sunnyvale, CA, USA). The vocal folds, ventricular mucosa, and arytenoid cartilage were grossly preserved. Final pathology revealed a low-grade cartilaginous neoplasm consistent with low-grade chondrosarcoma. CONCLUSIONS AND RELEVANCE: Chondrosarcoma of the larynx is a rare entity that accounts for roughly 1% of laryngeal neoplasms. Recent trends in otolaryngology literature and practice suggest that low-grade chondrosarcomas can be effectively treated with organ-preserving, conservative surgery. Transoral robotic surgery offers numerous advantages over both open and endoscopic approaches. To our knowledge, this is the first report in the literature describing the successful use of transoral robotic surgery for the resection of a laryngeal chondrosarcoma.

Reduced sociability is a core feature of autism spectrum disorders (ASD) and is highly disabling, poorly understood, and treatment refractory. To elucidate the biological basis of reduced sociability, multiple laboratories are developing ASD-relevant mouse models in which sociability is commonly assessed using the Social Choice Test. However, various measurements included in that test sometimes support different conclusions. Specifically, measurements of time the "test" mouse spends near a confined "stimulus" mouse (chamber scores) sometimes support different conclusions from measurements of time the test mouse sniffs the cylinder containing the stimulus mouse (cylinder scores). This raises the question of which type of measurements are best for assessing sociability. We assessed the test-retest reliability and ecological validity of chamber and cylinder scores. Compared with chamber scores, cylinder scores showed higher correlations between test and retest measurements, and cylinder scores showed higher correlations with time spent in social interaction in a more naturalistic phase of the test. This suggests that cylinder scores are more reliable and valid measures of sociability in mouse models. Cylinder scores are reported less commonly than chamber scores, perhaps because little work has been done to establish automated software systems for measuring the former. In this study, we found that a particular automated software system performed at least as well as human raters at measuring cylinder scores. Our data indicate that cylinder scores are more reliable and valid than chamber scores, and that the former can be measured very accurately using an automated video analysis system in ASD-relevant models.
