Sagittal craniosynostosis treatment

Sagittal craniosynostosis has been treated using both cranial remodeling techniques and modification of the sagittal strip craniectomy. A more recent technique is to implant springs in conjunction with a suturectomy to transversely expand the parietal bones to accommodate the growing brain

Surgery of sagittal craniosynostosis has a long history. The first surgeries of this type (linear craniotomies) were performed by Lannelongue and Launet in the early XIX century. Treatment results were rather controversial and reoperations were often needed. In that period, the new trend in surgery was not widely supported 1).

Is less easy with conventional calvarial remodeling surgery if they are older than 1 year. Gradual cranial vault compression with distractors can be another option in these cases 2).

A survey of neurosurgeons and craniofacial plastic surgeons worldwide shows that for young infants treated, the bicoronal incision is most commonly used and a greater number of surgeons do not use drains. A great variability in the transfusion protocols used in the care of these patients as well as a low reoperation rate were also found. The latter however may suggest a lack of strict monitoring in most centers 3).

Spring assisted cranioplasty (SAC) has become an accepted treatment for patients with sagittal craniosynostosis.

Of U.S. craniofacial and neurosurgeons, 94 percent routinely admit patients to the intensive care unit following cranial vault remodeling for correction of sagittal synostosis.

Despite the common practice of postoperative admission to the intensive care unit following cranial vault remodeling for sagittal craniosynostosis, the authors suggest that postoperative care be considered on an individual basis, with only a small percentage requiring a higher level of care 4).

Case series

2017

100 patients with sagittal synostosis who underwent each of the 3 surgical correction techniques before June 30, 2013, were identified. Clinical, operative, and process of care variables and their associated specific charges were analyzed along with overall charge.

The study included 300 total patients. Endoscopic strip (ES) patients had fewer transfusion requirements (13% vs 83%, P < .001) than TCV patients, fewer days in intensive care (0.3 vs 1.3, P < .001), and a shorter overall hospital stay (1.8 vs 4.2 d, P < .001), and they required fewer revisions (1% vs 6%, P = .05). The mean charge for the endoscopic procedure was $21 203, whereas the mean charge for the TCV reconstruction was $45 078 ( P < .001). ES patients had more preoperative computed tomography scans (66% vs 44%, P = .003) than OSS patients, shorter operative times (68 vs 111 min, P < .001), and required fewer revision procedures (1% vs 8%, P < .001). The mean charge for the endoscopic procedure was $21 203 vs $20 535 for the OSS procedure ( P = .62).

The ES craniectomy for sagittal synostosis appeared to have less morbidity and a potential cost savings compared with the TCV reconstruction. The charges were similar to those incurred with OSS craniectomy, but patients had a shorter length of stay and fewer revisions 5).

2015

Arko et al. retrospectively reviewed patients who presented to the Children's Hospital of Philadelphia with a diagnosis of sagittal synostosis from August 2011 to November 2014. A pooled data set was created to compare our institutional data to previously published work. A comprehensive literature review was performed of all previous studies describing the spring-mediated cranioplasty (SMC) technique, as well as other techniques for sagittal synostosis correction.

Twenty-two patients underwent SMC at our institution during the study period. Patients were 4.2 months of age on average, had a mean blood loss of 56.3 ml, and average intensive care unit and total hospital stays of 29.5 hours and 2.2 days, respectively. The cranial index was corrected to an average of 73.7 (SD 5.2) for patients who received long-term radiological follow-up. When comparing the authors' institutional data to pooled SMC data, blood loss and length of stay were both significantly less (p = 0.005 and p < 0.001, respectively), but the preoperative cranial index was significantly larger (p = 0.01). A review of the SMC technique compared with other techniques to actively expand the skull of patients with sagittal synostosis demonstrated that SMC can be performed at a significantly earlier age compared with cranial vault reconstruction (CVR).

The authors found that their institutional modifications of the SMC technique were safe and effective in correcting the cranial index. In addition, this technique can be performed at a younger age than CVRs. SMC, therefore, has the potential to maximize the cognitive benefits of early intervention, with lower morbidity than the traditional CVR 6).


Sagittal craniosynostosis treatment complications

Iatrogenic pseudoaneurysm of the superficial temporal artery after surgery for craniosynostosis is a complication that has never been described in the pertinent literature. Although reported for other types of surgeries, no case has been described in the pediatric population.

Anania et al from the Division of Neurosurgery, Giannina Gaslini Institute, Genoa, Italy report on a case of pseudoaneurysm of the superficial temporal artery occurred 9 days after corrective surgery for scaphocephaly. They describe also the management of this complication. Pseudoaneurysm is an exceptional complication in surgery for craniosynostosis, but it should be considered in case of swelling in the temporal region 7).
