Craniosynostosis: A Reversible Pathology?
imageThe formation of the cranial sutures, in utero, occurs when the ossification of the skull bones reaches predestined positions around gestational week 15 to 20. Craniosynostosis, and the consequent skull shape deformities, is treated with surgery including osteotomies of the fused sutures. The occasional appearance of a new suture in the osteotomy lines has previously been described as sporadic events. In this retrospective study, a 4-year consecutive series of osteotomies combined with springs for craniosynostosis were systematically analysed regarding the appearance of neosutures. In total, 84 patients were included and in 16 patients (19%) a new radiologically normal suture appeared in a part of the suture that was completely closed preoperatively. Additionally, in 7 patients (8%) a new suture appeared in a part of the suture that had a discernible suture prior to surgery. In conclusion, in this consecutive and well-defined patient cohort operated for craniosynostosis, the formation of a neosuture is not a rare, and speculatively not a random, event. The appearance of a new suture long after the normal time period for suture formation in utero indicates that the craniosynostosis may just as well be caused by disturbed formation of the suture as actual premature closure.
Routine Postoperative Admission to the Intensive Care Unit Following Repair of Nonsyndromic Craniosynostosis: Is it Necessary?
Background: Cranial vault surgery for craniosynostosis is generally managed postoperatively in the intensive care unit (ICU). The purpose of the present study was to examine our center's experience with the postoperative management of otherwise healthy patients with nonsyndromic craniosynostosis (NSC) without routine ICU admission. Methods: A retrospective cohort study of patients with NSC operated using a variety of vault reshaping techniques in our pediatric center between 2009 and 2017 was carried out. Patients with documented preexisting comorbidities that would have required admission to the ICU regardless of the surgical intervention were excluded. Results: A total of 102 patients were included in the study. Postoperatively, 100 patients (98%) were admitted as planned to a general surgical ward following observation in the recovery room. Two patients (2%) required ICU admission due to adverse intraoperative events. There were no patients who required transfer to the ICU from the recovery area or surgical ward. Within the surgical ward cohort, 6 patients (6%) had minor postoperative complications that were readily managed on the surgical floor. Postoperative anemia requiring transfusion was the most common complication. Conclusion: The results from this study suggest that otherwise healthy patients with NSC undergoing cranial vault surgery can potentially be safely managed without routine admission to the ICU postoperatively. Key elements are proper preoperative screening, access to ICU should an adverse intraoperative event occur and necessary postoperative surgical care. The authors hope that this experience will encourage other craniofacial surgeons to reconsider the dogma of routine ICU admission for this patient population.
An Interdisciplinary Approach to Treatment of Adult Facial Arteriovenous Malformations: A Review of the Literature and A Single Institution's Experience With “Late” Surgical Resection and Aesthetic Reconstruction
imageBackground: Arteriovenous malformations (AVMs) are high flow vascular anomalies that are difficult to manage given their high recurrence rate. At this time, the optimal treatment of AVMs involves embolization and surgical resection. However, few studies have examined patient outcomes after a delayed surgical resection approach. Methods: A retrospective chart review of all patients presenting to a single institution with vascular malformations from 2000 to 2016 was performed. Patients with facial AVMs that underwent operative management were included. Records were reviewed for patient characteristics, lesion natural history, operative timing after embolization (<72 vs >72 hours), and outcomes. Results: 11 patients fulfilled the inclusion/exclusion criteria. Nine patients were female, with an average age at resection of 29.1 years. Three patients had hemi/mid-facial AVMs, 1 patient had a nasal AVM, 3 patients had labial AVMs, 1 patient had an AVM on the chin, and 1 had a periorbital AVM. Average time between embolization and primary resection was 8.6 days (range 1–24). No complications requiring reoperation occurred in any patient. Average follow-up was 32.6 months, with 2 recurrences at a mean of 47.6 months. Timing of resection, Schobinger stage, and resection completeness did not significantly affect recurrence (P >0.05). Lesion size >6 cm in any dimension was significantly associated with recurrence (P = 0.018). Conclusion: Compared to early resection, delayed (>72 h) surgical resection after embolization of facial AVMs is a viable treatment option and results in non-inferior recurrence rates (25 vs 14% respectively over a 40-month period).
Midface Growth in Patients With Unilateral Cleft Lip and Palate Treated With a Nasoalveolar Molding Protocol
imageThis retrospective cohort study aimed to determine the impact of a nasoalveolar molding (NAM) protocol on midface growth in school-aged children with non-syndromic unilateral cleft lip and palate (UCLP). Data from 56 consecutively treated, NAM-prepared, Caucasian patients with non-syndromic UCLP from a single US cleft palate center were compared to pooled center data based on 56 patients with non-syndromic UCLP treated at 2 Eurocleft centers that did not use presurgical infant orthopedics (non-PSIO). Lateral cephalograms were obtained and 28 landmarks were identified. Published cephalometric measurements from Eurocleft centers were used for comparison. Seven cephalometric measurements (SNA, SNB, ANB, A’N’B’, G’-Sn’-Pg’, Sn-CT-LS, ANS-Me/N-Me%), available or derivable for both centers, were analyzed. Means and standard deviations for the 7 measurements were calculated for the NAM center. Student's t-tests were used to compare group means for 6 of the measures and a test of proportion was used for ANS-Me/N-Me%. No significant differences were found between the NAM protocol-prepared group and the Eurocleft non-PSIO centers on any of the 7 analyzed cephalometric relationships after accounting for false discovery rate. The NAM treatment protocol does not appear to impact skeletal or soft tissue facial growth in school-aged children with non-syndromic UCLP.
The Endocranial Bifrontal Angle: A Longitudinal Evaluation in Two Patients With Metopic Synostosis
imageBackground: Metopic craniosynostosis is the early fusion of the skull bones in the frontal region of the metopic suture, which leads to trigonocephaly and neurological sequelae. Severe metopic craniosynostosis is defined by an endocranial bifrontal angle less than 124°, and this serves as a threshold for neurological deficit and significant skull deformity, typically warranting surgical treatment. Methods: Two patients presented for evaluation for metopic craniosynostosis. Low-dose computed tomography imaging was performed in both patients due to concern for underlying metopic craniosynostosis. Results: In both patients, imaging demonstrated an initial endocranial bifrontal angle greater than 124°. However, in subsequent evaluation, the children developed severe trigonocephaly, and an angle less than 124°. Conclusion: The authors present 2 patients with metopic craniosynostosis, which became severe over time. The authors hypothesize that this may be due to an initial smaller head circumference, which later experienced rapid growth, leading to narrower endocranial bifrontal angle. Therefore, younger children with suspected metopic craniosynostosis, with initially smaller head circumference (but not meeting the threshold of 124°) should be followed longitudinally, as the head circumference may demonstrate greater narrowing subsequently into a more severe form of trigonocephaly and possibly surgery.
