OBJECT The surgical management of infants with sagittal synostosis has traditionally relied on open cranial vault remodeling (CVR) techniques; however, minimally invasive technologies, including endoscope-assisted craniectomy (EAC) repair followed by helmet therapy (HT, EAC+HT), is increasingly used to treat various forms of craniosynostosis during the 1st year of life. In this study the authors determined the costs associated with EAC+HT in comparison with those for CVR. METHODS The authors performed a retrospective case-control analysis of 21 children who had undergone CVR and 21 who had undergone EAC+HT. Eligibility criteria included an age less than 1 year and at least 1 year of clinical follow-up data. Financial and clinical records were reviewed for data related to length of hospital stay and transfusion rates as well as costs associated with physician, hospital, and outpatient clinic visits. RESULTS The average age of patients who underwent CVR was 6.8 months compared with 3.1 months for those who underwent EAC+HT. Patients who underwent EAC+HT most often required the use of 2 helmets (76.5%), infrequently required a third helmet (13.3%), and averaged 1.8 clinic visits in the first 90 days after surgery. Endoscope-assisted craniectomy plus HT was associated with shorter hospital stays (mean 1.10 vs 4.67 days for CVR, p < 0.0001), a decreased rate of blood transfusions (9.5% vs 100% for CVR, p < 0.0001), and a decreased operative time (81.1 vs 165.8 minutes for CVR, p < 0.0001). The overall cost of EAC+HT, accounting for hospital charges, professional and helmet fees, and clinic visits, was also lower than that of CVR (

56,990.46, respectively, p < 0.0001). CONCLUSIONS Endoscope-assisted craniectomy plus HT is a less costly surgical option for patients than CVR. In addition, EAC+HT was associated with a lower utilization of perioperative resources. Theses findings suggest that EAC+HT for infants with sagittal synostosis may be a cost-effective first-line surgical option.

Background: The authors’ purpose was to document speech outcome after cleft palate repair in patients with syndromic versus nonsyndromic Robin sequence. They also report the results of secondary correction of velopharyngeal insufficiency using a superiorly based pharyngeal flap or double-opposing Z-palatoplasty. Methods: Charts of patients with Robin sequence and cleft palate between 1980 and 2007 were reviewed. Data collected included date of birth, sex, syndrome/association, cleft palatal type (Veau class I or II), age at palatoplasty, incidence of palatal fistula, postoperative speech assessment, videofluoroscopic results, need for secondary operation for velopharyngeal insufficiency, and type of secondary operation (pharyngeal flap or double-opposing Z-palatoplasty). Results: The authors identified 140 patients with Robin sequence who had palatal closure. Postoperative speech evaluation was available for 96 patients (69 percent). A syndrome or association was identified in 42 patients (30 percent). Primary palatoplasty was successful in 74 patients (77 percent); speech was characterized as competent and competent to borderline competent. The authors found a significantly higher incidence of velopharyngeal insufficiency following palatal repair for syndromic (38 percent) than nonsyndromic Robin sequence (16 percent). (p = 0.039). In patients with velopharyngeal insufficiency, competent or borderline competent speech was determined after double-opposing Z-palatoplasty (two of five patients) or pharyngeal flap (eight of 10 patients). Conclusions: The rate of velopharyngeal insufficiency in syndromic Robin sequence is significantly greater than in nonsyndromic Robin sequence. The authors prefer pharyngeal flap for velopharyngeal insufficiency in patients with Robin sequence, whether syndromic or nonsyndromic, without retrognathism or signs/symptoms of obstructive sleep apnea. CLINICAL QUESTION/LEVEL OF EVIDENCE: Risk, II.

AbstractSagittal synostosis has been successfully managed with numerous surgical techniques. Nevertheless, few data on long-term outcomes exist to justify use of one surgical technique over another. In this study, we compared children with surgically corrected sagittal synostosis to their age-matched control subjects to assess the longevity of their corrections. Furthermore, the outcomes of open repairs were compared with endoscopic repairs.Following institutional review board approval, three-dimensional photographs of patients who underwent surgical reconstruction for nonsyndromic sagittal synostosis were analyzed to determine biparietal and anterior-posterior diameter, circumference, cephalic index, cranial vault volume, cranial height, and forehead inclination. Thirteen patients who had undergone open repair, including 6 total cranial vault and 7 modified-pi reconstructions, and 6 patients who had undergone endoscopic strip craniectomy with barrel-stave osteotomies and postoperative helmeting were compared with nonsynostotic age-matched control subjects. Mean follow-up was 97.5 months after open and 48.9 months after endoscopic repair. Student t tests were used for analysis. In the second arm of this study, 33 patients who had undergone endoscopic repair were compared with the 13 patients who had undergone open repair; mean follow-up was 24.8 months after endoscopic repair. Linear regression models were used to adjust for age and sex.After comparing three-dimensional photographs of children who were more than 3 years postoperative from surgical correction for sagittal synostosis with their age-matched control subjects, no statistically significant differences were found in any of the measured parameters. In addition, no differences were detected between open reconstruction versus endoscopic repair, suggesting equivalence in final results for both procedures.

BackgroundPatients with metopic craniosynostosis are traditionally treated with fronto-orbital advancement to correct hypotelorism and trigonocephaly. Alternatively, endoscopic-assisted treatment comprises narrow ostectomy of the fused suture followed by postoperative helmet therapy. Here we compare the preoperative and 1-year postoperative results in open versus endoscopic repairs. MethodsWe reviewed preoperative and 1-year postoperative three-dimensional reconstructed computed tomography scans of patients treated for nonsyndromic metopic craniosynostosis by either open (n = 15) or endoscopic (n = 13) technique. Hypotelorism was assessed by interzygomaticofrontal distance and intercanthal distance. Trigonocephaly was assessed by 2 independent angles: first, an axial-plane two-dimensional angle between zygomaticofrontal suture bilaterally and the glabella (ZFR-G-ZFL); second, an interfrontal angle (IFA) between the most anterior point from a reconstructed midsagittal plane and supraorbital notch bilaterally. Age-matched scans of unaffected patients (n = 28) served as controls for each postoperative scan. ResultsPatients with open repair (9.5 ± 1.8 months) were older at time of surgery than patients with endoscopic repairs (3.3 ± 0.4 months) (P = 0.004). Male-to-female ratios were equivalent at roughly 7:3 in both groups. Preoperatively, the endoscopic group had worse hypotelorism and ZFR-G-ZFL than the open group (P ⩽ 0.04). After accounting for preoperative differences, all of the postoperative measurements (ie, interzygomaticofrontal distance, intercanthal distance, ZFR-G-ZFL angle, IFA) of the 2 groups were statistically equivalent (P ≥ 0.135). Trigonocephaly was significantly improved after repair in both the open (8 degrees [ZFR-G-ZFL] and 18 degrees [IFA]) and endoscopic (13 degrees [ZFR-G-ZFL] and 16 degrees [IFA]) groups (P < 0.001). Postoperative measures in both groups were equivalent to controls (0.12 < P < 0.89). Intrarater reliability ranged from 0.93 to 0.99 for all measurements. ConclusionOur retrospective series shows that endoscopic and open repairs of metopic craniosynostosis are equivalent in improving hypotelorism and trigonocephaly at 1-year follow-up. Additional studies are necessary to better define minor differences in morphology, which may result from the different techniques.

IntroductionBariatric surgery has emerged as an effective method of combating the morbid obesity epidemic. However, the massive weight loss that follows may result in contour changes that can affect body image and quality of life. Our study examines the effects and consequences of bariatric surgery and subsequent body contouring on body image and quality of life. MethodsPatients were prospectively followed up through their experience with bariatric surgery and subsequent body contouring surgery. Using 2 validated survey instruments, the Multidimensional Body-Self Relations Questionnaire and the Short Form 36 (SF-36), patients completed questionnaires preoperatively and at 6, 12, and 24 months postoperatively. Mean scores were determined by repeated measures analyses of variance F tests. ResultsOne hundred seventy-five patients were surveyed before bariatric surgery, with noted declines in survey completion at 6, 12, and 24 months. Appearance Evaluation scores improved significantly at all intervals (P = 0.0033), as did Body Area Satisfaction Scale and Appearance Orientation scores (P = 0.0079 and P = 0.044, respectively). While Overweight Preoccupation and Self-Classified Weight scores decreased over time, only the latter was significant (P < 0.0001). The composite SF-36 score for patients awaiting bariatric surgery (54.1%) with postoperative scores at 6 (67.6%,), 12 (at 74.0%), and 24 (76.7%) months being significantly higher (P < 0.0001).The body contouring group consisted of 41 patients who primarily had lower body procedures, with 31 patients surveyed at 6 months and 27 patients at 12 months. For this cohort, Appearance Evaluation and Body Area Satisfaction Scale scores both improved significantly (P = 0.0001 and P = 0.0005, respectively) whereas Appearance Orientation scores declined significantly (P = 0.0055). Both Overweight Preoccupation and Self-Classified Weight scores decreased with only the latter being statistically significant (P = 0.0286). Postoperative SF-36 scores at 6 (72.9%) and 12 (64.5%) months were no different than patients awaiting body contouring (71.3%). ConclusionsUsing 2 validated survey instruments, we show that patients undergoing bariatric surgery have improvements in body image and quality of life. Subsequent postbariatric body contouring surgery results in further improvements in body image. Our findings provide measurable evidence for the value of body contouring after significant weight loss, which may favor greater insurance coverage for this patient population.

Background: Preoperative severity and postoperative success for patients with sagittal synostosis are measured by cephalic index, but this metric does not describe the appropriateness of euryon location. The authors hypothesize that cephalic index in patients with sagittal synostosis is an inaccurate measure of scaphocephaly. Methods: Preoperative and 1-year postoperative cranial computed tomographic scans of children with sagittal synostosis treated before 6 months of age by either total calvarial reconstruction or endoscope-assisted craniectomy and helmet therapy (n = 10 for each) were reviewed retrospectively. The location of euryons in age-matched controls was measured as a fraction of the glabella-opisthocranion distance (horizontal point of maximum width) and as the fraction of the nasion-vertex vertical distance (vertical point of maximum width). Cephalic index at this ideal location (normative cephalic index) and traditional cephalic index were determined in all patients. Results: Ideal euryon location from preoperative controls was 56 percent by the horizontal point of maximum width and 56 percent by the vertical point of maximum width. Normative cephalic index (0.60) was significantly less than traditional cephalic index (0.66) in patients preoperatively (p < 0.001) and remained smaller postoperatively (0.68 versus 0.73) for patients who underwent open reconstruction (p < 0.001). Patients treated endoscopically also had a smaller normative cephalic index (0.71) than traditional cephalic index (0.76) postoperatively (p < 0.001). Conclusions: Anterocaudal displacement of euryon in patients with sagittal synostosis influences cephalic index. Normative cephalic index, assessed at ideal euryon location, is a more accurate measure of preoperative severity and postoperative outcome. CLINICAL QUESTION/LEVEL OF EVIDENCE: Diagnostic, III.

Background:Previous studies have shown that open cranial vault remodeling does not fully address the endocranial deformity. This study aims to compare endoscopic-assisted suturectomy with postoperative molding helmet therapy to traditional open reconstruction by quantifying changes in cranial base morphology and posterior cranial vault asymmetry. Methods:Anthropometric measurements were made on pre- and 1-year postoperative three-dimensionally reconstructed computed tomography scans of 12 patients with unilateral lambdoid synostosis (8 open and 4 endoscopic-assisted). Cranial base asymmetry was analyzed using: posterior fossa deflection angle (PFA), petrous ridge angle (PRA), mastoid cant angle (MCA), and vertical and anterior–posterior (A–P) displacement of external acoustic meatus (EAM). Posterior cranial vault asymmetry was quantified by volumetric analysis. Results:Preoperatively, patients in the open and endoscopic groups were statistically equivalent in PFA, PRA, MCA, and A–P EAM displacement. At 1 year postoperatively, open and endoscopic patients were statistically equivalent in all measures. Mean postoperative PFA for the open and endoscopic groups was 6.6 and 6.4 degrees, PRA asymmetry was 6.4 and 7.6%, MCA was 4.0 and 3.2 degrees, vertical EAM displacement was −2.3 and −2.3 millimeters, and A–P EAM displacement was 6.8 and 7.8 millimeters, respectively. Mean volume asymmetry was significantly improved in both open and endoscopic groups, with no difference in postoperative asymmetry between the 2 groups (P = 0.934). Conclusions:Patients treated with both open and endoscopic repair of lambdoid synostosis show persistent cranial base and posterior cranial vault asymmetry. The results of endoscopic-assisted suturectomy with postoperative molding helmet therapy are similar to those of open calvarial vault reconstruction.

BackgroundCraniosynostosis causes significant cranial deformity in the pediatric population. Open and endoscopic-assisted surgeries have led to increasingly successful management of this condition. Following surgical reconstruction, subsequent development of postnatal synostosis of previously patent sutures have been described and noted to be most frequently associated with multisuture synostosis patients with syndromic diagnoses. Very rarely, postsurgical new sutural fusion has been identified in nonsyndromic patients who initially present with isolated single-suture synostosis. The purpose of this study was to evaluate the incidence of new synostosis among patients who had undergone craniosynostosis reconstruction with either the open or endoscopic technique. MethodsPatients undergoing open and endoscopic surgery for nonsyndromic craniosynostosis were reviewed. Preoperative and postoperative imaging and clinical information were reviewed, and cases showing progressive cranial deformity were identified. ResultsThree (2.1%) of 145 patients undergoing open craniosynostosis surgery and 2 (1.7%) of 121 patients undergoing endoscopic surgery developed delayed fusion of an additional suture during follow-up. This was identified at a median of 16.4 months after initial surgery in the open group and 15.25 months after surgery in the endoscopic group. In patients undergoing open surgery, each patient developed new sagittal synostosis after initial presentation of coronal synostosis in 1 patient and metopic synostosis in 2 patients. In patients undergoing endoscopic surgery, each patient developed new coronal synostosis after sagittal repair. ConclusionsManagement of craniosynostosis has evolved over time with increasing availability of effective and safe treatments. During long-term follow-up, a small number of patients may develop premature closure of a different suture that did not undergo surgical manipulation. In our case, series, we identified 3 patients undergoing open surgery and 2 patients undergoing endoscopic surgery for nonsyndromic, single-suture craniosynostosis. This finding supports the necessity of long-term clinical follow-up and the utility of delayed imaging when clinical suspicion indicates.
