J Plast Reconstr Aesthet Surg 2024; 99:76-84. [PMID: 39357137 DOI: 10.1016/j.bjps.2024.09.044] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/27/2024] [Revised: 09/01/2024] [Accepted: 09/11/2024] [Indexed: 10/04/2024]
Abstract
BACKGROUND Preoperative severity of unicoronal synostosis varies greatly and involves the frontal bone, skull base and orbits. Degree of deformity affects long-term morphological and functional outcomes after surgery. The aim of this study was to describe the morphological heterogenicity and investigate its relation to patient-specific factors. MATERIALS AND METHODS In this retrospective cohort study, non-syndromic unicoronal synostosis patients treated between 2006 and 2022 at Necker Hospital, France or Uppsala University Hospital, Sweden, were included and matched to controls. Severity of skull base, orbital and posterior skull asymmetry, degree of anterior plagiocephaly and Harlequin deformity, lateralisation, head circumference, age, timing of metopic fusion and fusion of peri-pterionic sutures were investigated. RESULTS Ninety-five patients and ninety-three controls were included. Skull base asymmetry was linearly related to orbital asymmetry (p < 0.001), correlated with earlier CT scans (p = 0.004) and anterior (p < 0.001) and posterior (p = 0.03) plagiocephaly. Posterior plagiocephaly was more common in patients (31%) compared with controls (5%) (p < 0.001). A patent metopic suture above nine months of age was associated with severe Harlequin deformity (p = 0.04) and a lower head circumference when fused (p = 0.03). Fronto-sphenoidal suture fusion was associated with later CT scans (p < 0.001) and less skull base asymmetry (p = 0.002). Spheno-parietal fusion was correlated with decreased skull base asymmetry (p = 0.03). Right lateralisation was more common in females. CONCLUSIONS Heterogenicity of unicoronal synostosis seems to be predominantly explained by variability in skull base morphology. Peri-pterionic fusions might limit deformity.

Long-term outcomes after surgical correction of anterior plagiocephaly secondary to isolated frontosphenoidal synostosis: a systematic review and two illustrative cases. Childs Nerv Syst 2024:10.1007/s00381-024-06572-9. [PMID: 39138664 DOI: 10.1007/s00381-024-06572-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/27/2024] [Accepted: 08/07/2024] [Indexed: 08/15/2024]
Abstract
PURPOSE Anterior plagiocephaly ( AP), secondary to isolated frontosphenoidal synostosis (IFS), represents one of the rarest forms of craniosynostosis documented in medical literature. Therefore, there is a lack of comprehensive understanding regarding the long-term (> 2 years) postoperative outcomes of this minor suture synostosis. METHODS This study presents the long-term outcomes of two patients previously treated for IFS, detailing their clinical, imaging, and postoperative characteristics. Additionally, a systematic review was conducted following PRISMA criteria to summarize existing literature on the topic. The review specifically focuses on long-term aesthetic outcomes, reoperation rates, and complications following surgical intervention for IFS. RESULTS Four articles encompassing 12 patients were included in the systematic review. The review highlights clinical features, postoperative complications, reoperation rates, and long-term aesthetic outcomes. The mean age at surgery was 17.5 months (range 9.5-24 months), with an average age at diagnosis of 9.3 months (range 6-10 months). Fronto-orbital advancement was the predominant surgical approach described across all cases. The reoperation rate among patients was 16.6%, with only two cases reporting postoperative complications. In one of our cases, an intraoperative CT scan was utilized to illustrate real-time improvement in frontal bone alignment according to the surgical plan, which significantly contributed to positive long-term clinical outcomes observed during a follow-up period exceeding 24 months. CONCLUSION IFS, is a rare minor suture synostosis, significantly affects the aesthetic appearance of the forehead and necessitates consideration in the management of AP cases. Surgical intervention has shown minimal reoperation rates and excellent long-term prognosis. These findings are reinforced by recent institutional data and a comprehensive systematic review of the current literature.

Abstract
Craniosynostosis (CS) or the premature fusion of one or more cranial sutures in utero, or during the first years of life, can present in isolation or as a multisystem clinical disorder with a particular impact on visual function. Among ophthalmic complications, optic neuropathy is a significant cause of irreversible vision loss in these patients. Children with CS are at higher risk of developing elevated intracranial pressure which can lead to papilledema and, ultimately, optic atrophy. In addition, sometimes associated obstructive sleep apnea, abnormalities in central nervous system venous development, and Chiari malformation may contribute to optic neuropathy. Ophthalmologists have an important role in managing a number of coexistent ophthalmologic complications such as strabismus, anisometropia, amblyopia, ptosis, and exposure keratopathy in addition to maintaining surveillance for early signs of optic neuropathy; they play a critical consultative role contributing to the decision for primary or repeat decompressive surgery. In this article, we aim to review the etiology, diagnostic approach, and management of optic neuropathies in patients with craniosynostosis.

Abstract
PURPOSE To summarize the ophthalmic manifestations of unilateral coronal synostosis patients. METHODS We performed a literature search in the electronic database of PubMed, CENTRAL, Cochrane, and Ovid Medline guided by Preferred Reporting Items for Systematic Reviews and Meta-Analysis Statement for studies evaluating ophthalmic manifestations of unilateral coronal synostosis. RESULTS Unilateral coronal synostosis, also called unicoronal synostosis, may be mistaken for deformational plagiocephaly, an asymmetric skull flattening common in newborns. Characteristic facial features, however, distinguish the two. Ophthalmic manifestations of unilateral coronal synostosis include a "harlequin deformity", anisometropic astigmatism, strabismus, amblyopia, and significant orbital asymmetry. The astigmatism is greater on the side opposite the fused coronal suture. Optic neuropathy is uncommon unless unilateral coronal synostosis accompanies more complex multi-suture craniosynostosis. In many cases, surgical intervention is recommended; without intervention, skull asymmetry and ophthalmic disorders tend to worsen with time. Unilateral coronal synostosis can be managed by early endoscopic stripping of the fused suture and helmeting through a year of age or by fronto-orbital-advancement at approximately 1 year of age. Several studies have demonstrated that anisometropic astigmatism, amblyopia, and severity of strabismus are significantly lower after earlier intervention with endoscopic strip craniectomy and helmeting compared to treatment by fronto-orbital-advancement. It remains unknown whether the earlier timing or the nature of the procedure is responsible for the improved outcomes. As endoscopic strip craniectomy can only be performed in the first few months of life, early recognition of the facial, orbital, eyelid, and ophthalmic characteristics by consultant ophthalmologists enables expeditious referral and optimized ophthalmic outcomes. CONCLUSION Timely identification of craniofacial and ophthalmic manifestations of infants with unilateral coronal synostosis is important. Early recognition and prompt endoscopic treatment appears to optimize ocular outcomes.

J Clin Med 2023; 12:6224. [PMID: 37834867 PMCID: PMC10573795 DOI: 10.3390/jcm12196224] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/26/2023] [Revised: 09/17/2023] [Accepted: 09/23/2023] [Indexed: 10/15/2023] Open
Abstract
(1) Background: Non-syndromic unicoronal craniosynostosis (UCS) is associated with a high prevalence of ocular anomalies. Currently, the etiology of this association remains obscure, however, it is presumed to be primarily attributed to their orbital malformations and/or secondary to craniofacial surgery. We assessed pre-operative ophthalmological examinations of non-syndromic UCS patients and compared them with their postoperative outcomes and long-term follow-up. (2) Methods: A retrospective case series was conducted on medical records of patients with non-syndromic UCS at Sophia Children's Hospital, Rotterdam. Ophthalmologic examinations were collected at different time periods: T1 (first visit), T2 (<1 year after cranioplasty), and T3 (long-term follow-up at last visit). The McNemar's test was used for statistical analysis. (3) Results: A total of 101 patients were included, for whom examinations were available at T1 and T3. Patients had a mean age of 2.8 years (±2.7) and 9.5 (±4.9) at T1 and T3, respectively. At T1, 52 patients (51.5%) were diagnosed with strabismus, and 61 patients (60.4%) at T3. Vertical strabismus increased significantly from 23 patients (22.8%) at T1 to 36 patients (35.6%) at T3 (p = 0.011). Followed by astigmatism, which increased significantly from 38 (37.6%) at T1 to 59 (58.4%) patients at T3 (p = 0.001). T1 was available in 20 patients prior to fronto-orbital advancement (FOA), therefore, a sub-analysis was conducted on these patients, which was followed shortly after FOA at T2. Prior to FOA, strabismus was present in 11 patients (55.0%) and in 12 patients (60.0%) at T2. After FOA, strabismus worsened in two patients. (4) Conclusions: This study showed the high prevalence of ocular anomalies in patients with non-syndromic UCS before and after cranioplasty and at long-term follow-up. The findings of this study show that ophthalmic and orthoptic examinations are an important part of the optimal treatment of patients with non-syndromic UCS.

Abstract
Apert syndrome is characterized by eyelid dysmorphology, V-pattern strabismus, extraocular muscle excyclorotation, and elevated intracranial pressure (ICP). We compare eyelid characteristics, severity of V-pattern strabismus, rectus muscle excyclorotation, and ICP control in Apert syndrome patients initially treated by endoscopic strip craniectomy (ESC) at about 4 months of age versus fronto-orbital advancement (FOA) performed about 1 year of age. Methods Twenty-five patients treated at Boston Children's Hospital met inclusion criteria for this retrospective cohort study. Primary outcomes were magnitude of palpebral fissure downslanting at 1, 3, and 5 years of age, severity of V-pattern strabismus, rectus muscle excyclorotation, and interventions to control ICP. Results Before craniofacial repair and through 1 year of age, none of the studied parameters differed for FOA versus ESC treated patients. Palpebral fissure downslanting became statistically greater for those treated by FOA by 3 (P < 0.001) and 5 years of age (P = 0.001). Likewise, severity of palpebral fissure downslanting correlated with severity of V-pattern strabismus at 3 (P = 0.004) and 5 (P = 0.002) years of age. Palpebral fissure downslanting and rectus muscle excyclorotation were typically coexistent (P = 0.053). Secondary interventions to control ICP were required in four of 14 patients treated by ESC (primarily FOA) and in two of 11 patients initially treated by FOA (primarily third ventriculostomy) (P = 0.661). Conclusions Apert patients initially treated by ESC had less severe palpebral fissure downslanting and V-pattern strabismus, normalizing their appearance. Thirty percent initially treated by ESC required secondary FOA to control ICP.

Abstract
BACKGROUND Endoscopic suturectomy with postoperative helmeting (ESCH) has emerged as a successful treatment for craniosynostosis, initially in North America. We report early outcomes from the first cohort of ESCH patients treated in the United Kingdom (UK). METHODS Retrospective cohort study with electronic chart review. RESULTS 18 consecutive patients from the first ESCH procedure in UK (May 2017) until January 2020 identified. 12 male and 6 female infantsd, with a mean age of 4.6 months (range 2.5-7.8 months) and weight of 6.8 kg (range 4.8-9.8 kg). Diagnoses were metopic (n = 8), unicoronal (n = 7), sagittal (n = 2) and multi-sutural (n = 1) synostoses. Median incision length was 3 cm (range 2-10 cm). 16/18 received no blood products, with 2 (both metopics) requiring transfusion (1 donor exposure). Mean operative time (including anaesthesia) was 96 min (range 40-127 min). Median length of hospital stay was 1 night. 1 surgical complication (superficial infection). All patients are currently undergoing helmet orthosis therapy. So far, no patients have required revisional or squint surgery. CONCLUSION Early experience from the first UK cohort of ESCH suggests that this is a safe and well tolerated technique with low morbidity, transfusion and short hospital stay. Long-term results in terms of shape, cosmetic and developmental outcome are awaited.

Abstract
INTRODUCTION Among non-syndromic, single-suture craniosynostoses, unicoronal craniosynostosis (UCS) presents the highest rate of ophthalmic manifestations requiring a visual follow-up, due to the high risk of amblyopia. After birth or during childhood, children with UCS have a high risk to present an aniso-astigmatism and a strabismus. The aim of this study was to characterize clinical ophthalmologic findings associated with UCS in a paediatric cohort. METHODS This retrospective study included children admitted in our unit between 2015 and 2021, with isolated UCS treated in our institution and complete ophthalmological assessment comprising visual assessment, refractive status and oculomotor examination. Children with associated craniofacial disorders were excluded. RESULTS A total of 28 children met the inclusion criteria. Median age was 62 [13-192] months with a large proportion of girls (86%) and 71% of right-sided UCS. The mean best corrected visual acuity was 0.07 (±0.13) LogMAR, including 10 (36%) children with an amblyopia or history of amblyopia. Astigmatism was significantly higher on the contralateral side of the UCS than on the ipsilateral side, with a refractive cylinder error of 0.97 (±1.06) vs 0.56 (±0.68) diopters, respectively (p = 0.03). Strabismus was observed in 20 patients (71%) with a main pattern of esotropia with a vertical component. A pseudo-superior oblique palsy was found in 13 children (65%) with a median cyclodeviation of 8.7° [-5,4°-20.6°]. CONCLUSION Children with UCS experience a high rate of various visual manifestations. This study highlights their need for a strict ophthalmological follow-up, in order to early diagnose and prevent visual complications.

Predictors of Blood Transfusion for Endoscopic Assisted Craniosynostosis Surgery. J Craniofac Surg 2021; 33:1327-1330.

Abstract
ABSTRACT Blood loss is a main cause of morbidity after craniofacial procedures. The purpose of this study is to identify the incidence and predictors for transfusion of blood products in the endoscopic assisted strip craniectomy population. Data was prospectively collected from a single-center multi-surgeon cohort of 78 consecutive patients who underwent endoscopic assisted strip craniectomy for craniosynostosis between July 2013 and December 2020. The authors reviewed patient and treatment characteristics and outcomes. Of the 78 patients, 26 patients were transfused yielding an overall rate of transfusion of 33%. The most common fused suture was sagittal (n = 42, 54%) followed by metopic (n = 15, 19%), multiple (n = 10, 13%), coronal (n = 7, 9%) and finally lambdoid (n = 4, 5%). On univariate analysis, patients' weight in the transfusion cohort were significantly lower than those who did not receive a transfusion (5.6 ± 1.1 versus 6.5 ± 1.1 kg, P = 0.0008). The transfusion group also had significantly lower preoperative hemoglobin compared to the non-transfusion group (10.6 versus 11.1, P = .049). Eleven percent patients admitted to step-down received a transfusion, whereas 39% of patients admitted to the pediatric intensive care unit received a transfusion (P = 0.042). On multivariate analysis, only higher patient weight (operating room [OR] 0.305 [0.134, 0.693], P = 0.005) was protective against a transfusion, whereas colloid volume (OR 1.018 [1.003, 1.033], P = 0.019) predicted the need for a transfusion. Our results demonstrate that endoscopic craniosynostosis cases carry a moderate risk of transfusion. Individuals with lower weight and those that receive colloid volume are also at elevated risk.

Abstract
BACKGROUND Unicoronal craniosynostosis is associated with orbital restriction and asymmetry. Surgical treatment aims to both correct the aesthetic deformity and prevent the development of ocular dysfunction. We used orbital quadrant and hemispheric volumetric analysis to assess orbital restriction and compare the effectiveness of distraction osteogenesis with anterior rotational cranial flap (DO) and bilateral fronto-orbital advancement and cranial vault remodeling (FOAR) with respect to the correction of orbital restriction in patients with unicoronal craniosynostosis. METHODS A retrospective review of all patients with a diagnosis of unicoronal craniosynostosis and treated with either DO or FOAR from 2000 to 2019 was performed. Preoperative and postoperative total orbital volumes, as well as quadrant and hemispheric volume ratios, were calculated from 3-dimensional head computed tomography scans. Selected preoperative and postoperative orbital measurements, including the maxillary length of the orbit (MLO; zygomaticofrontal suture to the top of zygomatic arch) and the sphenoid length of the orbit (SLO; the top of sphenoid suture to the top of zygomatic arch), were also obtained. RESULTS Data were available for 28 patients with unicoronal craniosynostosis. Mean preoperative total orbital volume was significantly smaller on the synostotic side compared with the nonsynostotic side (10.94 vs 12.20 cm3, P = 0.04). Preoperative MLO and SLO were significantly longer on the synostotic side compared with the nonsynostotic side (MLO: 20.26 vs 17.75 mm, P < 0.001; SLO: 26.91 vs 24.93 mm, P = 0.01). Distraction osteogenesis and FOAR produced significantly different changes in orbital quadrant and/or hemispheric volume ratios on the nonsynostotic side but not on the synostotic side. CONCLUSIONS Before correction, patients with unicoronal craniosynostosis have significantly smaller total orbital volumes on the synostotic side compared with the nonsynostotic side and significantly greater MLO and SLO on the synostotic side compared with the nonsynostotic side. There is no significant difference between DO and FOAR with regard to correcting the observed orbital restriction in these patients.

Abstract
Craniosynostosis, a premature fusion of cranial sutures that can be isolated or syndromic, is a congenital defect with a broad, multisystem clinical spectrum. The visual pathway is prone to derangements in patients with craniosynostosis, particularly in syndromic cases, and there is a risk for permanent vision loss when ocular disease complications are not identified and properly treated early in life. Extensive advancements have been made in our understanding of the etiologies underlying vision loss in craniosynostosis over the last 20 years. Children with craniosynostosis are susceptible to interruptions in visual input arising from strabismus, refractive errors, and corneal damage; any of these aberrations can result in understimulation of the visual cortex during childhood neurodevelopment and permanent amblyopia. Elevated intracranial pressure resulting from abnormal cranial shape or volume can lead to papilledema and, ultimately, optic atrophy and vision loss. A pediatric ophthalmologist is a crucial component of the multidisciplinary care team that should be involved in the care of craniosynostosis patients and consistent ophthalmologic follow-up can help minimize the risk to vision posed by such entities as papilledema and amblyopia. This article aims to review the current understanding of neuro-ophthalmological manifestations in craniosynostosis and explore diagnostic and management considerations for the ophthalmologist taking care of these patients.

Abstract
BACKGROUND To report refractive outcomes, describe types of strabismus and evaluate the outcomes of surgical intervention for unilateral coronal synostosis (UCS) in paediatric patients. METHODS This study retrospectively included 30 UCS cases. Patients aged from 3 months to 6 years (median: 1.8 years) were enrolled from January 2018 to December 2019 at Shanghai Children's Hospital. Sixteen patients had all types of strabismus; 15 of these patients underwent surgery. RESULTS Refractive errors of 30 cases were included. In 60% of patients, astigmatism of 1.00D or more existed in not less than one eye at last record. Twenty (66.7%) patients had the larger amount of astigmatism in the contralateral eye. Fifteen patients received strabismus surgery, of whom 6 patients with monocular elevation deficiency (MED) underwent the standard Knapp procedure, with or without a horizontal deviation procedure. Fifteen cases were horizontally aligned within 5 prism dioptres (Δ). Six patients with MED (100%) had attained ≥25% elevation improvement after surgery, and the vertical deviation decreased from 25.83 Δ ± 4.92 Δ (range, 20 Δ-30 Δ) to 0.83 Δ ± 4.92 Δ after surgery (range, 0 Δ-10 Δ), for an improvement of 26.67 Δ ± 4.08 Δ (t = 16 P < 0.05). In 1 patient with esotropia, the horizontal deviation decreased from + 80 Δ to + 5 Δ after surgery. One patient was diagnosed with trichiasis and one with contralateral lacrimal duct obstruction. CONCLUSIONS Contralateral MED was also the main type of strabismus in UCS. Superior oblique muscle palsy was still the most common, as previously reported. There is a risk of developing a higher astigmatism and anisometropia in the contralateral eye to synostosis. Other ophthalmic disorders should be treated in a timely manner. TRIAL REGISTRATION The study was approved by the Institutional Review Board of Shanghai Children's Hospital (approval No. 2020R023-E01) and adhered to the tenets of the Declaration of Helsinki. Ethics approval was procured on March 30, 2020. This was a retrospective study. Written informed consent was sought from the patients' parents or legal guardians.

Abstract
OBJECTIVE To evaluate patient outcomes of minimally invasive endoscopic strip craniectomy (ESC) for craniosynostosis. STUDY DESIGN This is a retrospective cohort analysis (2004-2018) of 500 consecutive infants with craniosynostosis treated by ESC with orthotic therapy at a single center. Operative outcomes included transfusions, complications, and reoperations as well as head circumference change based on World Health Organization percentiles. Multivariable logistic regression was used to identify risk factors associated with blood transfusion. Paired t tests were used for within-patient comparisons and Fisher exact test to compare syndromic and nonsyndromic subgroups. RESULTS ESC was associated with low rates of blood transfusion (6.6%), complications (1.4%), and reoperations (3.0%). Risk factors for transfusion included syndromic craniosynostosis (P = .01) and multiple fused sutures (P = .02). Median surgical time was 47 minutes, and hospital length of stay 1 day. Transfusion and reoperation rates were higher among syndromic patients (both P < .001). Head circumference normalized by 12 months of age relative to World Health Organization criteria in infants with sagittal, coronal, and multisuture craniosynostosis (all P < .001). CONCLUSIONS ESC is a safe, effective, and durable correction of infantile craniosynostosis. ESC can achieve head growth normalization with low risks of blood transfusion, complications, or reoperation. Early identification of craniosynostosis in the newborn period and prompt referral by pediatricians allows families the option of ESC vs larger and riskier open reconstruction procedures.

Abstract
BACKGROUND Craniosynostosis is a condition in which 2 or more of the skull bones fuse prematurely. The spectrum of the disorder most commonly involves the closure of a single suture in the skull, but it can also involve syndromic diagnoses in which multiple skull bones and/or bones outside of the cranium are affected. Craniosynostosis can result in cosmetic deformity as well as potential limitations in brain growth and development, and the neurocognitive impact of the condition is just starting to be studied more thoroughly. Our knowledge regarding the genetics of this condition has also evolved substantially. In this review, the authors explore the medical and surgical advancements in understanding and treating this condition over the past century, with a focus on how the diagnosis and treatment have evolved. METHODS In this review article, the authors, who are the leaders of a craniofacial team at a major academic pediatric hospital, focus on single-suture craniosynostosis (SSC) affecting the 6 major cranial sutures and discuss the evolution of the treatment of SSC from its early history in modern medicine through the current state of the art and future trends. This discussion is based on the authors' broad experience and a comprehensive review of the literature. SUMMARY The management of SSC has evolved substantially over the past 100 years. There have been major advances in technology and medical knowledge that have allowed for safer treatment of this condition through the use of newer techniques and technologies in the fields of surgery, anesthesia, and critical care. The use of less invasive surgical techniques along with other innovations has led to improved outcomes in SSC patients. The future of SSC treatment will likely be guided by elucidation of the causes of neurocognitive delay in these children and assessment of how the timing and type of surgery can mitigate adverse outcomes.

Abstract
BACKGROUND Ocular abnormalities in craniosynostosis are a persistent concern for patients and providers, and some surgeons feel that early surgical intervention for synostosis alleviates the progression of ophthalmologic abnormalities. In contradistinction, the authors hypothesize that operating early will have no bearing on postoperative ophthalmologic outcomes. METHODS Single-suture craniosynostosis patients who underwent surgical correction between 1989 and 2015 were reviewed. Patients with multisuture craniosynostosis, syndromic diagnoses, no preoperative ophthalmology evaluation, and less than 2 years of follow-up were excluded. Logistic regression was used to determine odds of preoperative and postoperative ophthalmologic abnormalities by age, while controlling for patient-level covariates. RESULTS One hundred seventy-two patients met inclusion criteria. The median age at surgery was 10 months (interquartile range, 7 to 12.9 months). Increasing age at the time of surgery was associated with increased odds of preoperative ophthalmologic diagnoses (OR, 1.06; p = 0.037) but not postoperative diagnoses (OR, 1.00; p = 0.91). Increasing age at surgery was also not associated with increased odds of ophthalmologic diagnoses, regardless of timing (OR, 1.04; p = 0.08). Patients with coronal synostosis (OR, 3.94; p = 0.036) had significantly higher odds of preoperative ophthalmologic diagnoses. Patients with metopic (OR, 5.60; p < 0.001) and coronal (OR, 7.13; p < 0.001) synostosis had significantly higher odds of postoperative ophthalmologic diagnoses. CONCLUSIONS After reviewing an expansive cohort, associations of both overall and postoperative ophthalmologic diagnoses with age at surgery were not found. The authors' findings thus run counter to the theory that early surgical intervention lessens the likelihood of postoperative ophthalmologic diagnoses and improves ophthalmologic outcomes.

Abstract
BACKGROUND Posterior vault distraction (PVD) can rapidly expand calvarial volume in infancy. Limited data exist regarding its perioperative and postoperative safety profile. This study sought to investigate the patient profile, outcomes, and safety of PVD using a national pediatric database. METHODS Posterior vault distraction patients between 2012 and 2016 were isolated from the National Surgical Quality Improvement Program Pediatric database. Patient background, perioperative outcomes, and risk factors were analyzed using chi-squared, t test analysis, and multivariate regression. RESULTS Ninety-four patients who underwent PVD were isolated with 67 ultimately meeting inclusion criteria for the study. The majority of patients undergoing PVD had limited other documented comorbidities. No patients required reoperation or 30-day readmission. There were no incidences of stroke, surgical site infection, or death. Subdividing outcomes by specialty, plastic surgeons performed PVD on significantly older patients than neurosurgeons (188 days vs 138 days, P = 0.008). Increasing age was associated with increasing operative time (P < 0.001). Furthermore, increasing age is associated with greater absolute transfusion requirements (P = 0.018) and higher, but not significant, risk of requiring any volume of blood transfusion (P = 0.105). CONCLUSIONS Posterior vault distraction is a safe procedure to rapidly expand calvarial volume in the setting of craniosynostosis. Increasing patient age is the strongest predictor for prolonged operative time and higher blood transfusion volumes.

Abstract
BACKGROUND Minimally invasive approaches for the treatment of single-suture craniosynostosis are sometimes touted as equivalent to cranial vault reconstruction. While techniques for sagittal synostosis have been reviewed previously, evidence regarding open and less invasive surgical techniques for metopic, coronal, and lambdoid synostosis has yet to be reviewed. METHODS Systematic searches were performed using Embase.com and PubMed. Included studies reported short- or long-term outcomes, compared at least 2 standard techniques, discussed single-suture coronal, metopic, or lambdoid craniosynostosis, and enrolled at least 20 study participants. Two authors screened titles and abstracts, and also performed full text review and data extraction. Given heterogeneous outcomes, qualitative synthesis was performed after data extraction. RESULTS The search strategy yielded 2348 articles. Of these, 313 were removed as duplicates, and 1935 were excluded during title/abstract review. After full text review of 100 articles, 19 were selected for data extraction. The heterogeneity of outcomes precluded meta-analysis and required qualitative synthesis. While short-term outcomes indicated decreased morbidity of minimally invasive techniques, only 2 articles presented long-term reoperation rates. One study reported higher reoperation rates in the less invasive technique, and the second reported no reoperations in the median follow-up period of 33 months. CONCLUSION Studies comparing long-term outcomes between different surgical techniques for single-suture craniosynostosis remain deficient. The development of standardized outcome measures is essential, and prospective, multicenter studies are necessary to assess the long-term efficacy of these procedures.

Abstract
OBJECTIVE Despite increasing adoption of endoscopic techniques for repair of nonsagittal single-suture craniosynostosis, the efficacy and safety of the procedure relative to established open approaches are unknown. In this systematic review the authors aimed to directly compare open surgical and endoscope-assisted techniques for the treatment of metopic, unilateral coronal, and lambdoid craniosynostosis, with an emphasis on quantitative reported outcomes. METHODS A literature search was performed in compliance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Relevant articles were identified from 3 electronic databases (MEDLINE, EMBASE, and CENTRAL [Cochrane Central Register of Controlled Trials]) from their inception to August 2017. The quality of methodology and bias risk were assessed using the Effective Public Health Practice Project (EPHPP) Quality Assessment Tool for Quantitative Studies. RESULTS Of 316 screened records, 7 studies were included in a qualitative synthesis of the evidence, of which none were eligible for meta-analysis. These reported on 111 unique patients with metopic, 65 with unilateral coronal, and 12 with lambdoid craniosynostosis. For all suture types, 100 (53%) children underwent endoscope-assisted craniosynostosis surgery and 32 (47%) patients underwent open repair. These studies all suggest that blood loss, transfusion rate, operating time, and length of hospital stay were superior for endoscopically treated children. Although potentially comparable or better cosmetic outcomes are reported, the paucity of evidence and considerable variability in outcomes preclude meaningful conclusions. CONCLUSIONS Limited data comparing open and endoscopic treatments for metopic, unilateral coronal, and lambdoid synostosis suggest a benefit for endoscopic techniques with respect to blood loss, transfusion, length of stay, and operating time. This report highlights shortcomings in evidence and gaps in knowledge regarding endoscopic repair of nonsagittal single-suture craniosynostosis, emphasizing the need for further matched-control studies.

Abstract
OBJECTIVE In this systematic review and meta-analysis the authors aimed to directly compare open surgical and endoscope-assisted techniques for the treatment of sagittal craniosynostosis, focusing on the outcomes of blood loss, transfusion rate, length of stay, operating time, complication rate, cost, and cosmetic outcome. METHODS A literature search was performed in compliance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Relevant articles were identified from 3 electronic databases (MEDLINE, EMBASE, and CENTRAL [Cochrane Central Register of Controlled Trials]) from their inception to August 2017. The quality of methodology and bias risk were assessed using the Effective Public Health Practice Project Quality Assessment Tool for Quantitative Studies. Effect estimates between groups were calculated as standardized mean differences with 95% CIs. Random and fixed effects models were used to estimate the overall effect. RESULTS Of 316 screened records, 10 met the inclusion criteria, of which 3 were included in the meta-analysis. These studies reported on 303 patients treated endoscopically and 385 patients treated with open surgery. Endoscopic surgery was associated with lower estimated blood loss (p < 0.001), shorter length of stay (p < 0.001), and shorter operating time (p < 0.001). From the literature review of the 10 studies, transfusion rates for endoscopic procedures were consistently lower, with significant differences in 4 of 6 studies; the cost was lower, with differences ranging from $11,603 to $31,744 in 3 of 3 studies; and the cosmetic outcomes were equivocal (p > 0.05) in 3 of 3 studies. Finally, endoscopic techniques demonstrated complication rates similar to or lower than those of open surgery in 8 of 8 studies. CONCLUSIONS Endoscopic procedures are associated with lower estimated blood loss, operating time, and days in hospital. Future long-term prospective registries may establish advantages with respect to complications and cost, with equivalent cosmetic outcomes. Larger studies evaluating patient- or parent-reported satisfaction and optimal timing of intervention as well as heterogeneity in outcomes are indicated.

Abstract
Craniosynostosis (CS) is defined as the premature fusion of one or more calvarial sutures. This carries several consequences, including abnormal/asymmetric cranial vault development, increased intracranial pressure, compromised neurocognitive development, and craniofacial deformity. Definitive management is surgical with the goal of protecting cerebral development by re-establishing normal cranial vault expansion and correcting cosmetic deformity. In today's practice, CS surgery has advanced radically from simple craniectomies to major cranial vault reconstructive (CVR) procedures. More recently there has been considerable interest in endoscopic assisted surgery (EAS). Theoretical benefits include decreased operative time, morbidity, blood loss, postoperative pain, cost and faster recovery times. In this focused review, we summarize the current body of literature reporting clinical outcomes in EAS and review the data comparing EAS and CVR.

Abstract
INTRODUCTION Single Suture Craniosynostosis (SSC) occurs in 1 in 2,500 live births and is the most common type of craniosynostosis treated in most centers. Surgical treatment has evolved over the past century and open techniques are tailored to the specific suture type. Additionally, the concept of multi-disciplinary team care has proliferated and is becoming the standard of care for SSC. The combination of these evolutions, we believe, has improved the safety of cranial vault surgery for SSC. METHODS A retrospective review of patients participating in the Infant Learning Project at Seattle Children's Hospital who underwent cranial vault surgery for treatment of SSC between 2002 and 2006 was performed. Pre-operative assessment, surgical techniques, anesthetic and intraoperative events and both intra-operative and post-operative adverse events were analyzed. RESULTS Eighty eight patients fulfilled the inclusion criteria (42 sagittal, 23 metopic, 19 unicoronal, 4 lambdoid). Length of procedure varied (FOA 5.2 hrs, modified pi 2.5 hrs, total vault 4.9 hrs and switch cranioplasty 4.6 hrs), as did transfusion amount (FOA 385 mL, modified pi 216 mL, total vault 600 mL, switch cranioplasty 207 mL) although 99% of patients received a transfusion of some sort. There were no deaths and no major intraoperative complications. Minor events include; ET tube malposition (1), desaturation (1), acidosis (1), hypothermia (9), coagulopathy (2), Hct < 25 (55). Average hospital stay was 3.4 days with no major post-operative complications. One patient was readmitted to the ICU and 1 had a scalp hematoma, but no patients returned to the operating room within 6 months after surgery. DISCUSSION The surgical treatment of SSC has evolved from lengthy, risky procedures to become almost routine at most craniofacial centers. Additionally, the care for patients with SSC has evolved from a single provider to a multidisciplinary team concept based around protocols for workup, delivery of anesthesia, streamlined surgical procedures and post-operative care and assessment. This evolution has given open cranial vault surgery for SSC an acceptable safety profile.

Abstract
Various operative techniques are available for the treatment of craniosynostosis. The patient's age at presentation is one of the most important factors in the determination of the surgical modality. Minimally invasive suturectomy and postoperative helmet therapy may be performed for relatively young infants, whose age is younger than 6 months. It relies upon the potential for rapid brain growth in this age group. Its minimal invasiveness is also advantageous. In this article, we review the advantages and limitations of minimally invasive suturectomy followed by helmet therapy for the treatment of craniosynostosis.

Abstract
Frontoorbital advancement (FOA) improves forehead and superior orbital asymmetry associated with unilateral coronal synostosis but has little effect on facial asymmetry. This study compares frontofacial symmetry after FOA and endoscopically assisted suturectomy (ESC) and postoperative helmet therapy.A retrospective review of 2 cohorts of patients with nonsyndromic unilateral coronal synostosis who had either FOA or ESC was undertaken. Choice of procedure was determined by age of patient at referral (younger than 4 months, FOA or ESC; older than 4 months, only FOA). Vectra 3D imaging system (Canfield Imaging Systems, Fairfield, NJ) was used to capture and analyze three-dimensional digital images. Comparative anthropometric measurements were made and statistically analyzed.Twenty-two patients met the inclusion criteria; 11 underwent ESC at mean age of 2 months (range, 1-4 months) and 11 underwent FOA at mean age of 12 months (range, 8-25 months). Mean age at three-dimensional digital imaging was 45.9 months (range, 18-64 months) for the FOA group and 34.5 months (range, 20-66 months) for the ESC group (P = 0.054).There was no difference between the 2 groups with regard to supraorbital symmetry (P = 0.54). The ESC group exhibited better facial symmetry in midline deviation (3.6° vs 1.4°; P = 0.018), nasal tip deviation (5.6° vs 2.3°; P = 0.006), and middle facial depth (6.9 vs 4.4 mm; P = 0.042). Lower facial depth was similar (3.8 vs 2.3 mm; P = 0.54).Early ESC and helmet therapy results in comparable brow symmetry and better overall facial symmetry than FOA done in late infancy.

Abstract
BACKGROUND While there is a clear correlation between unilateral coronal synostosis (UCS) and ocular motility abnormalities, the literature provides little information as to the true epidemiology of strabismus, or the underlying etiology of these paralleled pathologies. The purpose of this study is to investigate the rate of oculomotor abnormalities associated with UCS and its management. METHODS A retrospective review of all patients identified to have single-suture, nonsyndromic UCS treated by fronto-orbital advancement at a tertiary craniofacial referral center from 1977 to 2013 was performed. Inclusion criteria mandated complete medical, surgical, and ophthalmological records. Patients were evaluated for strabismus both preoperatively and postoperatively, and as to whether eye muscle surgery was performed. RESULTS A total of 181 patients underwent treatment for UCS at our institution during the study period, of which 79 met the inclusion criteria. Twenty-nine patients had strabismus prior to any craniofacial surgical intervention. Following fronto-orbital advancement, 23 patients (46 %) developed a new onset strabismus. Fifty-five patients had no change in their preoperative ocular examination, and one patient had resolution of preoperative strabismus. Of the 51 patients who had postoperative strabismus, 30 went on to have eye muscle surgery. There were no statistically significant differences in gender (p=0.477), race (p=0.395), sidedness of suture involvement (p=0.552), or age at intervention (p=0.66) in comparing the group with new postoperative strabismus and those without. CONCLUSIONS This study sheds new light on the prevalence of strabismus in UCS, and more importantly, the risk of developing strabismus in the setting of conventional fronto-orbital advancement. This data will allow more accurate preoperative counseling and reinforces the important role of ophthalmologists as members of the multidisciplinary craniofacial team.

Abstract
INTRODUCTION Craniosynostosis is a rare condition that affects approximately one child in every 2,000 live births, and involves pathological fusion of two or more skull bones. Consequences of craniosynostosis include possible limitation of brain growth and cosmetic effects on the appearance of the child. Traditional repairs for these conditions over the past 3-4 decades have involved an open operation with a large skin incision and major manipulations of the skull bones. More recently, minimally invasive endoscopic techniques have been developed to release the skull bones, followed by postoperative treatment with either an external orthosis or internal springs and distractors to achieve the desired correction. METHODS In this review minimally invasive endoscopic repair will be reviewed. A general overview of the condition and techniques for correction will be discussed, followed by specific application of these surgeries for different craniosynostosis diagnoses. Attention to the subtleties of each specific condition will be highlighted. SUMMARY Over the past two decades clinical experience and a large number of publications have substantiated the benefits of minimally invasive endoscopic techniques for the treatment of craniosynostosis. These techniques have clear benefits for selected patients, and should be part of the standard of care for this condition at craniofacial centers.

Abstract
OBJECT The objective of this study was to present the authors' 16-year experience treating coronal craniosynostosis in infants using endoscopy-assisted techniques and postoperative cranial orthoses. METHODS A total of 128 synostosed coronal sutures in 115 patients were treated between 1996 and 2012 by endoscopically resecting a strip of bone containing the stenosed suture via a 2-3 cm incision made at the ipsilateral stephanion. Data were obtained from a prospective database. Following surgery, patients were fitted with custom cranial orthoses to help correct preoperative craniofacial deformities. All patients were followed closely with cranial anthropometric measurements and photographs. RESULTS The estimated mean blood loss was 20 ml (range 5-120 ml) and the estimated mean strip size was 0.6 cm × 10.7 cm. The mean surgical duration was 55 minutes (range 22-150 minutes). One patient underwent an intraoperative blood transfusion and 1 had a postoperative blood transfusion, for a total transfusion rate of 1.7%. Ninety-seven percent of patients were discharged on the first postoperative day. There were no deaths. Vertical dystopia correction of more than 80% from baseline was obtained in almost two-thirds of patients, with 51% achieving 100% correction. Nasal and sagittal craniofacial deviation (vertex-nasion-gnathion) correction greater than 80% was achieved in 80% of patients, with 77% achieving 100% correction. Supraorbital rim advancement of the ipsilateral eye was obtained in 98% of cases, with correction of frontal plagiocephaly the last deformity to achieve correction. CONCLUSIONS Early treatment of coronal synostosis with endoscopy-assisted craniectomy and postoperative molding helmets leads to significant correction of craniofacial abnormalities, including vertical dystopia, nasal deviation, sagittal misalignment, and ipsilateral proptosis. This treatment method is associated with minimal trauma, blood loss, and transfusion rates, and typically only requires 1 overnight stay. This surgical approach is safe, effective, and associated with excellent results.

Novel use of an ultrasonic bone-cutting device for endoscopic-assisted craniosynostosis surgery. Childs Nerv Syst 2013; 29:1163-8. [PMID: 23386175 DOI: 10.1007/s00381-013-2043-6] [Citation(s) in RCA: 19] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/10/2012] [Accepted: 01/25/2013] [Indexed: 10/27/2022]
Abstract
PURPOSE Endoscopic-assisted craniosynostosis surgery is associated with less blood loss and shorter operative times as compared to open surgery. However, in infants who have low circulating blood volumes, the endoscopic approach is still associated with significant blood loss. A major source of blood loss is the bone that is cut during surgery. We discuss the novel use of an ultrasonic bone-cutting device for craniosynostosis surgery, which decreases bone bleeding. This device, which has primarily only been used for spine and skull base surgery, may help reduce blood loss in these infants. METHODS All patients with single suture craniosynostosis who were operated on with the use of an ultrasonic bone-cutting device were identified. The information retrospectively recorded from patient charts included patient age, suture involved, blood loss, operative times, complications, preoperative hemoglobin, postoperative hemoglobin, length of hospital stay, and follow-up times. RESULTS Thirteen patients (12 males, 1 female) underwent surgery with an ultrasonic bone-cutting device during the reviewed period. The average age (±standard deviation) of the patients was 11.8 (±1.6) weeks. Four patients had metopic synostosis and nine patients had sagittal synostosis. The average surgery time was 84 (±13) min. The median (interquartile range) blood loss was 20 (10-70) cc. No patients required blood transfusions. Three patients had dural tears. CONCLUSION We demonstrate the novel use of an ultrasonic bone-cutting device for endoscopic-assisted craniosynostosis surgery. This device limited blood loss while maintaining short operative times for infants with low circulating blood volumes.

Abstract
PURPOSE To compare long-term ophthalmic outcomes in infants treated for unilateral coronal synostosis (UCS) by endoscopic strip craniectomy (ESC) and helmet therapy with those treated by fronto-orbital advancement (FOA). METHODS Consecutive patients with UCS, uncomplicated by other suture synostosis, were identified by a retrospective review of medical records. Assessment of presence of amblyopia, cycloplegic refraction, strabismus, and strabismus surgical intervention at all visits was recorded. RESULTS Between 2004 and 2010, 22 patients were treated by FOA (mean follow-up, 21.5 months) and 21 patients with ESC and helmet therapy (mean follow-up, 23.5 months). The mean aniso-astigmatism was equal; however, the SD was greater for those treated by FOA (P < 0.05). A more severe pattern of strabismus developed in those treated by FOA (P < 0.0001). Those treated by FOA were more likely to have amblyopia (P = 0.0015) and to undergo surgical correction of their strabismus (odds ratio, 6.3:1). CONCLUSIONS Children with UCS treated with ESC and helmeting had less severe overelevation in adduction, amblyopia, extremes of astigmatism, and less need for strabismus surgery than those treated by FOA. Although the reason for these more favorable outcomes remains uncertain, we speculate that the earlier timing of ESC or differences in the anatomical changes resulting from the two procedures may play a role.

Abstract
PURPOSE More than 60 different mutations have been identified to be causal in syndromic forms of craniosynostosis. The majority of these mutations occur in the fibroblast growth factor receptor 2 gene (FGFR2). The clinical management of syndromic craniosynostosis varies based on the particular causal mutation. Additionally, the diagnosis of a patient with syndromic craniosynostosis is based on the clinical presentation, signs, and symptoms. The understanding of the hallmark features of particular syndromic forms of craniosynostosis leads to efficient diagnosis, management, and long-term prognosis of patients with syndromic craniosynostoses. METHODS A comprehensive literature review was done with respect to the major forms of syndromic craniosynostosis and additional less common FGFR-related forms of syndromic craniosynostosis. Additionally, information and data gathered from studies performed in our own investigative lab (lab of Dr. Muenke) were further analyzed and reviewed. A literature review was also performed with regard to the genetic workup and diagnosis of patients with craniosynostosis. RESULTS Patients with Apert syndrome (craniosynostosis syndrome due to mutations in FGFR2) are most severely affected in terms of intellectual disability, developmental delay, central nervous system anomalies, and limb anomalies. All patients with FGFR-related syndromic craniosynostosis have some degree of hearing loss that requires thorough initial evaluations and subsequent follow-up. CONCLUSIONS Patients with syndromic craniosynostosis require management and treatment of issues involving multiple organ systems which span beyond craniosynostosis. Thus, effective care of these patients requires a multidisciplinary approach.

Abstract
PURPOSE This paper aims to present a 15-year experience treating coronal craniosynostosis with endoscopic-assisted techniques and postoperative cranial orthotic therapy. METHODS A total of 100 patients with coronal craniosynostosis were treated between 1996 and 2010. There were 36 males and 64 females. A single 2-cm incision was made halfway between anterior fontanelle and the squamosal on the affected side. Using endoscopic-assisted visualization, a strip of bone was removed between the aforementioned points. Following surgery, all patients were placed in cranial orthoses to assist in the correction of the craniofacial deformity. RESULTS Mean estimated blood loss was 20 cm(3); only one patient required a transfusion. Mean length of stay was 1 day. Mean surgery time was 54 min. There were no mortalities. There was significant correction of vertical dystopia (66 % from baseline) and midsagittal plane deviation (80 % from baseline). CONCLUSIONS Endoscopic-assisted craniectomy for treatment of coronal craniosynostosis in very young infants followed by cranial molding is associated with excellent long-lasting results and minimal morbidity and no mortality.

Abstract
Object
The primary goals of treatment in the infant with craniosynostosis are to correct the deformity and allow for adequate brain growth in as safe and effective a manner as possible. Herein, the authors present the results of treating craniosynostosis using an endoscope-assisted strip craniectomy and postoperative helmet therapy (EASC + PHT) in the hopes of providing further evidence of its role in the treatment of multiple different forms of craniosynostosis. This is a retrospective review of the patients treated with this technique at Children's Hospital Boston.
Methods
The electronic medical records of all children with craniosynostosis treated using this technique were reviewed retrospectively. A priori, data were collected for deformity type, patient age at surgery, number of transfusions, operative time, length of hospital stay, and anthropometric measurements.
Results
One hundred seventy-three patients (61 females and 112 males) were treated at our institution between July 2004 and March 2011 with EASC + PHT. The mean operative time was 46.30 minutes. Eight (4.6%) of the 173 patients received blood transfusions. The average length of hospital stay was 1.35 days, with the majority of patients being discharged the day after surgery. All complications and any patient who required additional craniofacial reconstructions are discussed. In addition, a subgroup analysis was done for patients who had undergone surgery and had longer than 1 year of follow-up.
Conclusions
The authors' growing database of patients supports the experiences described by others that early treatment of craniosynostosis with an EASC + PHT is a safe and efficacious technique. In addition, cost reduction due to decreased hospital stay and limitation of blood transfusions are demonstrable benefits associated with the use of this technique.

Abstract
Craniosynostosis is a condition in which 1 or more cranial sutures fuse prematurely, often secondary to a fibroblast growth factor receptor (FGFR) mutation, typically involving FGFR2 or FGFR3. This mutation may occur sporadically or in the setting of a genetic syndrome and typically presents within the first few days of life or in early infancy. Most commonly, the sagittal and coronal sutures are involved, although involvement of the lambdoidal and/or metopic sutures is not uncommon. Surgical correction is undertaken both for cosmetic purposes and to relieve raised intracranial pressure, both of which can be severe, depending on the sutures involved. We report on 2 children who presented in their first year of life with synostosis involving: in one instance, a single squamous temporal suture, and in the other, both squamous temporal sutures. The initial presentation and clinical courses of these 2 patients are highly distinct from one another, although both ultimately did quite well after extensive cranial remodeling. To the best of our knowledge, only a handful of patients with squamous synostosis have been reported in the medical literature.

Abstract
BACKGROUND AND PURPOSE To review the surgical management of five vertical strabismus syndromes secondary to anatomical abnormalities. These syndromes are: 1) craniosynostosis; 2) "heavy eye syndrome" of high myopia; 3) Brown syndrome; 4) upshoot-downshoot in Duane retraction syndrome (DRS); and 5) antielevation syndrome after inferior oblique anteriorization. METHODS The syndromes are presented from evolving to well-accepted surgical management practices based on review of the current literature. RESULTS Surgical management techniques discussed include: 1) excyclotorsion of the muscle cones inducing elevation in adduction craniosynostosis, and surgery to stabilize the globe vertically in adduction in this situation; 2) loop myopexy to prevent prolapse of the elongated, highly myopic eye posteriorly between the superior and lateral recti; 3) superior oblique tenotomy and lengthening procedures to address inability to elevate the adducted eye in Brown syndrome; 4)Y-splitting of the lateral rectus to stabilize the adducted globe vertically in Duane retraction syndrome; and 5) re-recession of the anteriorized inferior oblique to a position posterior to the inferior rectus insertion in anti-elevation syndrome. CONCLUSIONS The surgeon can, through careful surgical management techniques, alter the form of anatomy in these conditions and thereby provide more normally functioning binocular systems.
