Abstract
PURPOSE To evaluate the refractive outcome and strabismus at 5 years of age, in children operated for various types of non-syndromic craniosynostosis, and further analyse the refractive and strabismic development over time. METHODS Eighty-nine children, who had undergone operations for non-syndromic craniosynostosis, were examined at 5 years of age. These children also underwent ophthalmological examination preoperatively and up to 1 year after the operation. An age-matched control group including 32 healthy children was also recruited. Strabismus and eye motility were registered. Refraction was measured in cycloplegia. RESULTS There was a difference regarding the refractive outcome between the different types of craniosynostosis. Higher values of hypermetropia were found in the metopic craniosynostosis group on both eyes. In the unicoronal craniosynostosis group, high values of hypermetropia and a higher degree of astigmatism were found on the side contralateral to the craniosynostosis. Strabismus was found in 11/88 children of whom 10/11 had unicoronal craniosynostosis. A vertical deviation on the side ipsilateral to the fused suture was highly prevalent (6/10 cases). Ophthalmological dysfunctions were rare in children operated for sagittal craniosynostosis. CONCLUSION Ocular manifestations such as strabismus, astigmatism and anisometropia were highly prevalent in children operated for unilateral coronal craniosynostosis. Children operated for metopic craniosynostosis had higher rates of hypermetropia. The screening and follow-up protocols need to be tailored with regard to the type of craniosynostosis.

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.

[PMID: 37762999 PMCID: PMC10531492 DOI: 10.3390/jcm12186059] [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: 08/23/2023] [Revised: 09/13/2023] [Accepted: 09/14/2023] [Indexed: 09/29/2023] Open
Abstract
(1) Background: Patients with unicoronal craniosynostosis (UCS) often show torticollis which can result from either an ocular cause or contraction of the sternocleidomastoid muscle. For clinicians, it is crucial to know the prevalence of ocular torticollis (OT) to ensure appropriate referral for treatment. Furthermore, associated ophthalmic features with OT in these patients are scarcely described. The aim of this study was to determine the prevalence of OT in non-syndromic UCS patients and investigate its associated ophthalmic features. (2) Methods: In this descriptive cross-sectional study medical records of non-syndromic UCS patients treated between 1994-2022 in one tertiary care hospital in The Netherlands were retrospectively reviewed. Collected data included: diagnosis and type of torticollis, binocular single vision (BSV), strabismus, ocular motility, alphabetical patterns, refractive error, and amblyopia. Patients were classified as OT, based on their ophthalmic and/or orthoptic diagnosis. Prevalence was determined with the 95% CI using the Clopper-Pearson exact test. Associations between OT and the ophthalmic features were determined using Chi-square or Fishers' exact test and its effect size was calculated using Cramer's V. (3) Results: In total, 146 patients were included, of whom 57 had torticollis. An ocular cause for the torticollis was found in 54 patients. The prevalence of OT was 37% (n = 146; 95% CI [0.292-0.454]). Significant associations were found between OT and strabismus (p < 0.001), ocular motility abnormalities (p < 0.001), alphabetical patterns (p < 0.001), and amblyopia (p = 0.002). BSV (p = 0.277) and refractive error (p = 1.0) were not significantly associated with OT. However, in OT the BSV was relatively poor (42.1%) and more frequently absent (26.3%) compared to the non-torticollis group (7% poor and 16.3% absent). In both groups, excyclotorsion was predominantly present (62.3%). (4) Conclusions: In 95% of cases, torticollis in UCS patients is ocular-related. Overall, one in three patients with UCS have OT. This study emphasizes the importance of a timely referral of all patients with UCS with torticollis to an orthoptist and/or ophthalmologist, specialized in diagnosing and treatment of OT, before considering physiotherapy.

Abstract
Early endoscopic-assisted correction of unicoronal and metopic synostosis is an excellent, safe, cost-effective, and highly effective option for affected patients. Although open calvarial remodeling has a place in the armamentarium of the craniofacial team, the skull base changes seen in endoscopic-assisted techniques are unparalleled. The procedures are associated with low morbidity and no mortality. There is minimal blood loss, decreased operating time, significantly reduced blood transfusion rates, decreased hospitalization length, decreased cost, and less pain and swelling. Early diagnosis and referral for surgical evaluation are critical to obtaining these results.

[PMID: 33972704 PMCID: PMC9046153 DOI: 10.1038/s41433-021-01458-5] [Citation(s) in RCA: 8] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/08/2020] [Accepted: 02/04/2021] [Indexed: 11/09/2022] Open
Abstract
OBJECTIVE To determine visual outcomes and prevalence of amblyogenic risk factors in children with Apert, Crouzon, Pfeiffer and Saethre-Chotzen syndromes. METHODS We conducted a single-centre, retrospective chart review of patients assessed at our unit between October 2000 and May 2017. Our outcome measures were as follows: age at first and last examination, refraction, horizontal ocular alignment, alphabet pattern deviations, anterior segment appearance, fundus examination findings, visual evoked potentials (VEPs) and genetics. The study's primary endpoint was the proportion of children achieving best-corrected visual acuity (BCVA) ≥ 6/12 in the better eye at final visit, as per UK driving standards. RESULTS 165 patients were included in this study. Breakdown of diagnoses was as follows: Crouzon (n = 60), Apert (n = 57), Pfeiffer (n = 14) and Saethre-Chotzen (n = 34). 98 patients were male. Of 133 patients with full BCVA data available, 76.7% achieved BCVA ≥ 6/12 in the better eye. Of 122 patients, anisometropia >1.00 dioptre sphere (DS) affected 18.9% and astigmatism ≥1.00DS in at least one eye affected 67.2%. Of 246 eyes, 48.4% had oblique astigmatism. Of 165 patients, 60 had exotropia and 12 had esotropia. 48 of 99 patients demonstrated 'V' pattern. On multivariable logistic regression, nystagmus (p = 0.009) and ON involvement (p = 0.001) were associated with decreased vision in the worse eye. Normal VEPs were associated with better BCVA (p = 0.036). CONCLUSION There was a high prevalence of amblyogenic factors, however, the majority achieved BCVA ≥ 6/12 in their better eye. Optic neuropathy and nystagmus had the most significant impact on vision. VEPs can help the in overall assessment of visual function.

Abstract
Background: The aim of this study was to describe the ophthalmic abnormalities and their prevalence in craniosynostosis prior to craniofacial surgery. Methods: A systematic search was conducted on Medline OVID, Embase, Cochrane, Google Scholar, Web of Science Core Collection. Inclusion criteria were English papers, children aged <18 years with non-syndromic and syndromic craniosynostosis, case reports, case series, and case-control studies. A system of domains was established consisting of an anatomic and functional ophthalmic domain. A meta-analysis of single proportions was carried out using random effects model and pooled mean proportions with 95% confidence intervals (CI) were calculated. Results: Thirty-two papers analyzing 2027 patients were included. Strabismus was the most common anomaly in non-syndromic craniosynostosis: Horizontal strabismus was highest prevalent in unicoronal craniosynostosis (UCS) 19% (95% CI 9–32), followed by vertical strabismus 17% (95% CI 5–33). In syndromic craniosynostosis, horizontal strabismus was most prevalent in Crouzon syndrome 52% (95 CI 26–76), followed by Apert syndrome 50% (95% CI 42–58). Vertical strabismus was most prevalent in Saethre-Chotzen 60% followed by Muenke’s syndrome 36%. Furthermore, astigmatism was the second most reported outcome in non-syndromic craniosynostosis and highest prevalent in UCS 35% (95% CI 21–51). In syndromic craniosynostosis, astigmatism was most frequently seen in Crouzon syndrome 43% (95% CI 22–65), followed by Apert syndrome 34% (95% CI 14–58). Moreover, in syndromic craniosynostosis, 5–40% had a decrease in visual acuity (VA) ≤ 0.3 LogMAR in the better eye and 11–65% had a VA ≤ 0.3 LogMAR in at least one eye. Discussion: This review demonstrates the high prevalence of ocular anomalies in non-syndromic and syndromic craniosynostosis. A multidisciplinary and systematic approach is needed for the screening and optimal treatment of these conditions in a timely manner.

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.

Abstract
BACKGROUND This study aims to collect local Malaysian data regarding the ophthalmic features and complications in craniosynostosis patients who attended the Combined Craniofacial Clinic (CFC) in University Malaya Medical Centre (UMMC). METHODS Retrospective study of medical notes of craniosynostosis patients who attended the CFC in UMMC from 2014 to December 2020. RESULTS Out of 37 patients, 29 had syndromic craniosynostosis, and 8 had non-syndromic craniosynostosis. Visual impairment was present in 32.1% of patients. Causes for visual impairment were as follows - amblyopia (25.0%), exposure keratopathy (3.6%), and optic atrophy (3.6%). Hypermetropia and myopia were each seen in 20.6% of patients. Astigmatism was seen in 47.1% of patients, and 29.1% had anisometropia. Proptosis was present in 78.6% and lagophthalmos in 53.3% of patients. Strabismus in primary position occurred in 51.7% of patients. Thirty-one percent of the patients had exposure keratopathy. Optic disc atrophy was seen in 13.7% of patients, and 8.3% had optic disc swelling. Optic disc swelling was resolved in all patients who underwent craniofacial surgery. CONCLUSION Our experience in Malaysia was consistent with previously reported data on ophthalmic features of craniosynostosis patients. Additionally, we found that non-syndromic craniosynostosis patients are also at risk of ocular complications just as much as syndromic patients. Appropriate treatment of amblyogenic risk factors, ocular complications, and timely detection of papilledema, and prompt surgical intervention are crucial in preserving long-term visual function in these patients.

Abstract
BACKGROUND The purpose of this prospective study is to compare perioperative morbidity and strabismus rates between traditional fronto-orbital advancement reconstruction (FOAR) and fronto-orbital distraction osteogenesis (FODO) in unicoronal craniosynostosis (UCS). METHOD A consecutive group of 15 patients undergoing FODO for isolated UCS were compared to a contemporaneous group of 15 patients undergoing traditional FOAR for UCS. Patient age, operative time, blood loss, blood replacement, technical details of the surgery, length of stay, complications, and strabismus rates were documented and compared statistically using chi-square and Student t test with a significance value of 0.05. RESULTS The 15 patients undergoing FODO were younger (6.3 and 9.8 months, P < 0.05), experienced less operative time for the initial procedure (111 versus 190 minutes, P < 0.01), less blood loss (26% versus 50% of total blood volume, P < 0.01), and less blood replacement (40% versus 60% of total blood volume, P < 0.05). One patient in the FODO group experienced a new-onset strabismus postoperatively compared with 5 in the FOAR group (P < 0.05). There were no complications requiring a return to the operating room in either group. CONCLUSIONS Fronto-orbital distraction osteogenesis for the treatment of isolated UCS is associated with a favorable perioperative morbidity profile and a decreased incidence of postoperative strabismus compared with traditional FOAR. These positive factors are tempered by the need for an additional procedure for removal of the device and lack of long-term outcomes data on the technique.

Abstract
Aims Craniosynostosis is a congenital condition characterised by premature fusion of one or more cranial sutures. The aim of this study was to analyse ophthalmic function before and after cranial surgery, in children with various types of non-syndromic craniosynostosis. Methods Children referred to Uppsala University Hospital for surgery of non-syndromic craniosynostosis were examined preoperatively. Visual acuity was measured with Preferential Looking tests or observation of fixation and following. Strabismus and eye motility were noted. Refraction was measured in cycloplegia and funduscopy was performed. Follow-up examinations were performed 6–12 months postoperatively at the children’s local hospitals. Results One hundred twenty-two children with mean age 6.2 months were examined preoperatively. Refractive values were similar between the different subtypes of craniosynostosis, except for astigmatism anisometropia which was more common in unicoronal craniosynostosis. Strabismus was found in seven children, of which four had unicoronal craniosynostosis. Postoperatively, 113 children were examined, at mean age 15.9 months. The refractive values decreased, except for astigmatism and anisometropia in unicoronal craniosynostosis. Strabismus remained in unicoronal craniosynostosis. Two new cases with strabismus developed in unicoronal craniosynostosis and one in metopic, all operated with fronto-orbital techniques. No child had disc oedema or pale discs preoperatively or postoperatively. Conclusion Ophthalmic dysfunctions were not frequent in children with sagittal craniosynostosis and preoperative ophthalmological evaluation may not be imperative. Children with unicoronal craniosynostosis had the highest prevalence of strabismus and anisometropia. Fronto-orbital techniques used to address skull deformity may be related to a higher prevalence of strabismus postoperatively.

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
The occurrence of secondary synostosis of coronal sutures at distance from H-craniectomy surgery for scaphocephaly concerns about 10% of children. Intracranial hypertension in these children remains exceptional but generally requires a surgical reoperation. Two children aged 3 and 5- months- old had been operated for scaphocephaly by H-craniectomy in two different hospital centers. Their clinical follow-up described a partial persistence of dolichocephalic deformity and an impression of parietal stenosis. During their growth, chronic headaches appeared with a complaint expressed at the ages of 4 and 5 years. In both cases, ophthalmic examination revealed significant bilateral papillary edema without loss of visual acuity. The imaging assessment (CT-scan and MRI) showed the absence of Chiari malformation and venous abnormality. For both, there was a compression image of the parietal lobes in relation to the persistence of a temporoparietal synostosis. An osteogenic parietal distraction permitted a volumetric brain expansion consecutive to the skull and meninges remodeling in only 6 months, associated with a leap forward acquisition, a normalization of the ophthalmic examination, and a complete loss of headaches. In conclusion, this new approach could be used in the case of chronic intracranial hypertension consecutive to a secondary parietal synostosis after a scaphocephaly surgery.

Abstract
BACKGROUND The purpose of this study was to determine what craniometric changes occur to both orbits of unicoronal craniosynostosis patients undergoing fronto-orbital advancement and remodeling, and which of these changes are associated with new onset of postoperative strabismus. METHODS A retrospective analysis was performed of the preoperative and postoperative orbits of 24 unicoronal craniosynostosis patients and the orbits of 24 control subjects, totaling 144 orbits. Eight parameters were evaluated using multivariate logistic regression analysis. One of the parameters was modified orbital index, an indicator of severity of harlequin deformity. RESULTS Significant differences in orbital dimensions and angles were present bilaterally in unicoronal craniosynostosis orbits when compared to controls. Fronto-orbital advancement and remodeling increased the ipsilateral unicoronal craniosynostosis orbital volume from 13,184 ± 2003 mm to 16,220 ± 2323 mm (p < 0.001). Ipsilateral horizontal cone angles were increased from 48 ± 5 degrees to 54 ± 7 degrees (p = 0.004). Ipsilateral vertical cone angles were decreased from 73 ± 8 degrees to 66 ± 10 degrees (p = 0.003). Ipsilateral modified orbital index improved from 0.83 ± 0.06 to 0.88 ± 0.06 (p = 0.003). Three of the 19 unicoronal craniosynostosis patients developed transient postoperative strabismus. Logistic regression analysis displayed a strong significant association between new-onset strabismus and a change in modified orbital index with a coefficient of 30.84 ± 14.51 (p < 0.05). CONCLUSIONS The orbital dysmorphology in unicoronal craniosynostosis is bilateral in nature, and it is not wholly treated with conventional fronto-orbital advancement and remodeling. The severity of ipsilateral orbital dysmorphology is correlated with the incidence of postoperative strabismus following conventional fronto-orbital advancement and remodeling. Future research is needed to develop strategies to mitigate the risk of development of strabismus in this group of patients. CLINICAL QUESTION/LEVEL OF EVIDENCE Risk, III.

Abstract
OBJECTIVE Unicoronal synostosis results in frontal plagiocephaly and is preferably treated before the patient is 1 year of age to prevent intracranial hypertension (ICH). However, data on the prevalence of ICH in these patients is currently lacking. This study aimed to establish the prevalence of preoperative and postoperative signs of ICH in a large cohort of patients with unicoronal synostosis and to test whether there is a correlation between papilledema and occipitofrontal head circumference (OFC) curve stagnation in unicoronal synostosis. METHODS The authors included all patients with unicoronal synostosis treated before 2 years of age at a single center between 2003 and 2013. The presence of ICH was evaluated by routine fundoscopy. The OFC growth curve was analyzed for deflection and in relationship to signs of ICH. RESULTS In total, 104 patients were included in this study, 84 (81%) of whom were considered to have nonsyndromic unicoronal synostosis. Preoperatively, none of the patients had papilledema as determined by fundoscopy (mean age at surgery 11 months). Postoperatively, 5% of patients with syndromic synostosis and 3% of those with nonsyndromic synostosis had papilledema, and this was confirmed by optical coherence tomography. Raised intracranial pressure was confirmed in 1 patient with syndromic unicoronal synostosis. Six of 78 patients had OFC stagnation, which was not significantly correlated to papilledema (p = 0.22). One child with syndromic unicoronal synostosis required repeated surgery for ICH (0.96%). CONCLUSIONS Papilledema was not found in patients with unicoronal synostosis when they underwent surgery before the age of 1 year and was also very rare during follow-up. There was no relationship between papilledema and OFC stagnation.

Abstract
The purpose of this study was to determine the effect of unilateral fronto-orbital advancement (FOA) or bilateral FOA on ocular aspects of plagiocephaly. A retrospective review of ocular findings in 16 patients with plagiocephaly was performed. Patients were divided into 2 groups: 12 patients who underwent bilateral FOA (bFOA) and 4 patients who underwent unilateral FOA (uFOA), and ocular findings were compared. One-half of patients showed strabismus in both groups, and all had exotropia. Hypertropia was found only on the same side of the plagiocephaly in 17% of the bFOA group and 25% of the uFOA group. One-third of the patients in the bFOA group and one-half of patients in the uFOA group had oblique muscle dysfunction. In terms of astigmatism, the degree of with-the-rule astigmatism on the contralateral side was larger in the bFOA group compared to the uFOA group (p = 0.030). The degree of with-the-rule astigmatism was larger on the contralateral side than the ipsilateral side (p = 0.005) in the bFOA group. Patients with abnormalities in ductions/versions had larger astigmatism on the contralateral side than those without abnormalities in ductions/versions. In conclusion, bilateral FOA could induce unwanted outcomes of larger astigmatism on the contralateral side. Astigmatism should be carefully evaluated after bilateral FOA.

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.

The prevalence of strabismus in unilateral coronal synostosis. Childs Nerv Syst 2015; 31:589-96.

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
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.

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
INTRODUCTION Anterior plagiocephaly due to the early unilateral fusion of the coronal suture is associated to a clinical phenotype characterized by the unilateral flattening of the frontal bone and the orbit and by the distortion and maldevelopment of adjacent cranial and facial bones. Homolateral anterior displacement of the ear and contralateral deviation of the nasal pyramid and mandible are other prominent clinical features. The differential diagnosis includes a variety of conditions characterized by facial asymmetry, namely, due to muscular alterations, anomalies of the visual function, congenital anomalies of the cervical spine and craniovertebral junction, abnormal pregnancy, and birth injuries. Anterior plagiocephaly is the direct cause of oculomotor anomalies, with a characteristic strabismus, and of progressive asymmetrical maldevelopment of the face, craniovertebral junction, and cervical spine. METHODS The medical literature was reviewed in regard to the epidemiology, clinical features, and radiological findings. Different categorization of the affected infants in specific subtypes according to the severity of the condition was analyzed. The aim was to contribute to a practical clinical classification to be utilized for the surgical indication and for predicting the prognosis according to the severity of the condition at presentation. CONCLUSIONS Anterior plagiocephaly represents the most challenging simple suture craniosynostosis. The clinical differential diagnosis with other forms of cranial asymmetry is possible on the grounds of mere clinical findings. A classification system is necessary not only for the establishment of surgical planning but also to predict the late cosmetic and functional outcomes.

Abstract
PURPOSE To determine the existence of a correlation between the vertical angle of strabismus and the vertical angle between the orbital axes in nonsyndromic plagiocephaly in childhood. METHODS Patients were included when diagnosed with plagiocephaly. Orthoptic measurements showed a vertical strabismus and three-dimensional computed tomographic (CT) imaging of the skull was available. Patients were excluded if plagiocephaly was part of a syndrome or if any surgical intervention had taken place before our measurements. Three-dimensional CT imaging was used to calculate the vertical angle between the orbital axes in 3 reference planes (VAO) perpendicular to a line of reference through the lower borders of the maxilla (VAOmax), both auditory canals (VAOaud), and the lower points of the external occipital protuberances (VAOocc). RESULTS Fourteen patients were included (mean age, 14 mo). Three-dimensional CT measurements showed a mean (SD) VAOmax of 1.70 (2.31) degrees, VAOaud of -1.54 (1.46) degrees, and VAOocc of -2.06 (4.29) degrees (a negative value indicates that the eye on the affected side was situated lower in the head). The mean vertical angle of strabismus was -2.39 (4.69) degrees in gaze toward the affected side, 3.66 (3.77) degrees in gaze ahead, and 8.14 (5.63) degrees in gaze toward the nonaffected side. The Pearson test showed no significant correlations. CONCLUSIONS The clinical observation that vertical strabismus in adult plagiocephaly is correlated with the vertical angle of the orbital axes could not be confirmed in young children.

Abstract
BACKGROUND Unilateral coronal synostosis results in ipsilateral retrusion of the forehead and superior orbital rim, shortening the elevation of the orbital roof and contralateral frontal bossing and orbital roof depression. This craniosynostosis is associated with the development of V-pattern strabismus and aniso-astigmatism. Since 2004 endoscopic strip craniectomy performed in patients by 3 months of age has been offered as an alternative to fronto-orbital advancement at 9 to 11 months of age. We compare the incidence and severity of V-pattern strabismus and aniso-astigmatism in children treated by these 2 procedures. METHODS A retrospective review identified 37 children with unilateral coronal synostosis treated with either fronto-orbital advancement or endoscopic strip craniectomy. Incidence and severity of V-pattern strabismus, fundus excyclotorsion, and aniso-astigmatism was recorded for an "early" examination (between 2 and 14 months of age) and a "late" examination (between 14 and 45 months of age). RESULTS Early examination revealed no statistical difference in severity of V-pattern strabismus or aniso-astigmatism between the 2 groups. At late examination there was a trend toward greater severity of V-pattern strabismus, an increase in excyclotorsion, and a statistically significant increase in the standard deviation of aniso-astigmatism in the cohort of children treated by fronto-orbital advancement. CONCLUSIONS Children with unilateral coronal synostosis treated by early endoscopic strip craniectomy may develop less severe V-pattern strabismus, excyclotorsion, and range of aniso-astigmatism than those treated by later fronto-orbital advancement. This is an early, retrospective, nonrandomized study with a short follow-up period; longer follow-up is necessary to confirm these results.

Abstract
PURPOSE To describe the prevalence and nature of anisometropic refractive errors in children with unilateral coronal craniosynostosis. METHODS Retrospective chart review of children with unilateral coronal craniosynostosis who underwent ophthalmic evaluation, including refraction. RESULTS Refraction was available for 25 of 61 children with unilateral coronal craniosynostosis. Of the 25, 56% had amblyogenic anisometropia. Of these, 79% had the greater refractive error contralateral to the coronal synostosis, mostly (91%) consisting of greater with-the-rule astigmatism in the contralateral eye. Seventy-two percent of Hispanic children had amblyogenic anisometropia, compared with only 14% of non-Hispanic children (p= 0.02). Although Hispanic children tended to receive both surgery and ophthalmic evaluation at older ages than non-Hispanic children, these factors did not appear to account for the difference between ethnicities. There was no detectable association between anisometropia and the timing of fronto-orbital advancement surgery. CONCLUSIONS Children with unilateral coronal craniosynostosis are at increased risk of developing amblyogenic levels of anisometropia in the eye contralateral to the synostosis and require early evaluation and refraction even in the absence of strabismus.

Abstract
The aim of this study was to assess various aspects of visual function in children with single-suture, non-syndromic craniosynostosis. Thirty-eight infants (28 males, 10 females; age range 3.5-13mo, mean age 7mo, 11 with plagiocephaly, 12 with trigonocephaly, and 15 with scaphocephaly), were assessed with a battery of tests specifically designed to assess various aspects of visual function in infancy. Thirty-two of the 38 infants had at least one abnormality on one of the aspects of visual function assessed. Abnormal eye movements were found in eight infants of the whole cohort and were mainly found in infants with plagiocephaly (6/11), who also had frequent visual field abnormalities (5/11). In contrast, fixation shift, an aspect of visual function related to the integrity of parietal lobes, was more frequently abnormal in patients with scaphocephaly. Our results suggest that the presence and severity of visual impairment is related to the type of craniosynostosis. Follow-up studies after surgical correction are needed to evaluate the possible beneficial effects of reconstructive surgery on visual function.

Abstract
PURPOSE Unilateral coronal synostosis alters orbital development and can be associated with strabismus, oblique muscle dysfunction, astigmatism, and amblyopia. While the ocular effects are most dramatic on the side of the fusion, the shape of the contralateral orbit is also abnormal and the effect of these changes on bilateral visual development has not been fully described. The purpose of this study was to analyze the incidence and laterality of astigmatism in children with unilateral coronal synostosis. METHODS We retrospectively reviewed the charts of 39 consecutive patients with unilateral coronal synostosis. Recorded data included the following: patient demographics, visual acuity, cycloplegic refraction, ocular motility, procedures for craniofacial and strabismus correction, and presence and treatment of amblyopia at each visit. RESULTS Twenty-one of 39 patients (54%) had 1.00 D or more astigmatism in at least one eye at their last recorded refraction. Sixteen of the 21 (76%) had aniso-astigmatism of 1.00 D or more. Of the 16, 14 (88%) had the greater degree of astigmatism in the contralateral eye. Fifteen of the 39 studied (38%) had amblyopia and, in 12 of these 15 patients (80%), the amblyopic eye was contralateral to the synostosis. Nineteen of 39 patients (49%) had greater ipsilateral fundus excyclotorsion, whereas only 1 of 39 (3%) had greater contralateral excyclotorsion. CONCLUSIONS Patients with unilateral coronal synostosis are at risk for developing a greater degree of astigmatism in the eye contralateral to the synostosis. Ocular disturbances in the contralateral eye, especially anisometropic amblyopia, must be considered when treating patients with this type of craniosynostosis.

Abstract
BACKGROUND/PURPOSE Despite the similar clinical phenotype of the Saethre-Chotzen and Muenke craniosynostoses, the 2 syndromes are now genotypically distinct. Patients with Saethre-Chotzen and Muenke syndromes carry mutations in the TWIST and fibroblast growth factor receptor (FGFR) 3 genes, respectively. We sought to assess possible ocular phenotypic differences in patients with mutations of either gene previously grouped according to phenotype only. METHODS A retrospective chart review was performed for 21 children with known mutations of the TWIST (n=10) or the FGFR3 (n=11) genes. Data gathered included patient sex, age, family craniofacial history, craniofacial and ophthalmic surgeries, type of strabismus, ptosis, cycloplegic refraction, visual acuity, the presence of amblyopia, nasolacrimal duct obstruction (NLDO), nystagmus, hypertelorism, epicanthal fold anomalies, and any ocular structural abnormalities. RESULTS In the TWIST group, ptosis was present in 90%, amblyopia in 70%, horizontal strabismus in 70%, vertical strabismus in 60%, NLDO in 60%, astigmatism in 50%, inferior oblique overaction (IOOA) in 40%, hyperopia in 40%, myopia in 30%, nystagmus in 30%, and optic nerve findings in 30%. In the FGFR3 group, ptosis was present in 36%, amblyopia in 18%, horizontal strabismus in 55%, vertical strabismus in 36%, NLDO in 0%, astigmatism in 9%, IOOA in 45%, hyperopia in 27%, myopia in 18%, nystagmus in 18%, and optic nerve findings in 27%. CONCLUSIONS Patients with TWIST gene mutations may have more ophthalmic abnormalities, including more strabismus, ptosis, NLDO, astigmatism, vertical deviations, and amblyopia compared with patients with FGFR3 gene mutations.

Abstract
Pansynostosis (fusion of all cranial sutures) and optic atrophy were found as incidental CT scan and ophthalmological findings in an 8-year-old who presented to the emergency room with scalp edema from tight 'cornrow' hair braiding. Cranial vault expansion was successfully performed. Ophthalmological problems have stabilized but have not reversed. Late presentation of craniosynostosis and the pathophysiology of secondary optic atrophy are discussed.

Abstract
AIMS To determine the visual outcome and prevalence of amblyogenic risk factors in children with craniosynostotic syndromes. METHODS The case notes of 141 children seen within the craniofacial unit were reviewed and information retrieved on date of birth, age at first and last examination, cycloplegic refraction at last visit, best corrected visual acuity at last visit, horizontal ocular deviation in primary position at first visit, and alphabet pattern if any. The presence of astigmatism, its magnitude, and orientation of axis were determined. RESULTS 40.3% of patients had 1 dioptre (D) of astigmatism or greater and, of these, 64% had oblique astigmatism in at least one eye. Anisometropia of 1D or more was found in 18% of patients (age matched normals 3.5%). Horizontal strabismus was found in 70% (38% exotropia, 32% esotropia). Visual outcome results showed 39.8% of patients (45 of 113) had visual acuity of 6/12 or worse in their better eye. CONCLUSION In the largest study to date a poor visual outcome was shown in children with Crouzon's, Pfeiffer's, Apert's, and Saethre-Chotzen syndromes (39.8% with 6/12 or worse in the better eye) together with significant prevalence of amblyogenic risk factors.

Abstract
The purpose of this article was to study the prevalence of strabismus and astigmatism in children with nonsyndromic plagiocephaly. Children with deformational plagiocephaly do not have an increased prevalence of strabismus compared with the general population but do have an increased prevalence of astigmatism, whereas children with nonsyndromic craniosynostotic plagiocephaly have an increased prevalence of strabismus and astigmatism. This observational cohort study retrospectively reviewed patients in a multidisciplinary craniofacial clinic between 1993 and 2001. Patients were referred for evaluation and management of plagiocephaly or craniosynostosis. One hundred eleven patients had deformational plagiocephaly, and 45 had synostotic plagiocephaly. Patients with lambdoid craniosynostosis, hemifacial microsomia, any syndromic form of craniosynostosis, or without a formal diagnosis were excluded. All patients underwent detailed ophthalmologic, ocular motility, and craniofacial examinations. Diagnosis was based on clinical and radiographic findings. Patients were evaluated between birth and age 14 years (mean = 13 months; SD = 22 months). Only 1 of 111 (<1%) patients with deformational plagiocephaly had an esodeviation, and none had an exodeviation. Three of 45 patients (7%) with synostotic plagiocephaly had an exodeviation, and none had an esodeviation. Eight of 93 patients (9%) with deformational plagiocephaly had unilateral astigmatism, and 14 (15%) had bilateral astigmatism (mean = 1.82 diopters). Three of 43 patients (7%) with synostotic plagiocephaly had unilateral astigmatism, and 9 (21%) had bilateral astigmatism (mean = 1.83 diopters). Patients with deformational plagiocephaly do not appear to have a higher prevalence of horizontal strabismus than the normal population. Exotropia is more common in patients with nonsyndromic craniosynostotic plagiocephaly than in the general population. The prevalence of astigmatism in patients with nonsyndromic craniosynostotic plagiocephaly appears to be greater than in the general population, but this higher prevalence requires further study.

Abstract
Clinical examination of patients affected by plagiocephaly or trigonocephaly reveals evident malformation of the orbits, and the ocular repercussions are pronounced when children are operated on at an advanced age. Since it is generally accepted that binocular vision is fully developed by approximately 6 months of age, a late correction of plagiocephalic or trigonocephalic skull deformities may be an obstacle to the development of normal visual function. For the present report we investigated astigmatism and strabismus in 53 children, 39 of whom were operated on for plagiocephaly and 14 for trigonocephaly. Traction on the ocular globe induced by the bony deformation caused by the craniosynostosis may explain astigmatism and strabismus.

Abstract
Trigonocephaly mostly occurs in isolated synostosis of the metopic suture, but 10-20% of patients are affected by complex syndromes, and in 2-5% the condition is familial. Intracranial hypertension has been observed in a minority of cases, but is never severe. Surgery is performed mainly for cosmetic reasons, following the standard principles of craniofacial surgery. Complications are rare and satisfactory cosmetic results are generally obtained. There is little likelihood for recurrent deformity.
