Treatment of Osteomyelitic Bone Following Cranial Vault Reconstruction With Delayed Reimplantation of Sterilized Autologous Bone: A Novel Technique for Cranial Reconstruction in the Pediatric Patient.

ABSTRACT: Craniosynostosis, a deformity of the skull caused by premature fusion of ≥1 cranial sutures, is treated surgically via endoscopic approaches or cranial vault remodeling. Postoperative infection is rare. Management of postoperative surgical site infections often involves culture-directed intravenous antibiotics and debridement, with removal of osteomyelitic bone and hardware in refractory cases. Removal of autologous bone in a pediatric patient presents a reconstructive challenge, as alloplastic options are not optimal in a growing child, especially in the setting of infection. Moreover, infants and small children have limited autologous bone options for reconstruction. We present our case of a young child who developed an infectious complication following cranial vault remodeling. The patient's demographic information, clinical presentation and postoperative course, radiologic features, surgical interventions, and treatment outcomes were reviewed. In our case, autologous osteomyelitic bone underwent tissue processing to eradicate the infection and complete skull reconstruction using the patient's own processed autologous bone was performed in a delayed fashion. The patient is now 1 year postoperative with no recurrence of infection. We present this case as a novel technique to eradicate infection in autologous bone, allowing for delayed autologous cranial reconstruction.

Intracranial complications of pediatric rhinosinusitis: Identifying risk factors and interventions affecting length of hospitalization.

OBJECTIVE: To identify risk factors and interventions affecting length of hospitalization (LOH) and clinical outcome in children with intracranial complications of rhinosinusitis. METHODS: Retrospective chart review of 12 children hospitalized at 2 academic medical centers for intracranial complications of rhinosinusitis over the past 5 years. RESULTS: 12 patients were identified with an average age at presentation of 13 years old. 92% were male and 75% were African American. The most common presenting symptoms were fever and headache. Localizing neurological symptoms including hemiparesis and aphasia, in addition to seizures occurred in 33% of patients and increased LOH significantly (33 versus 15 days, p = 0.03). Epidural (EA) and subdural abscesses (SA) were the most common intracranial complications. 58% of patients were initially treated with a combination of open neurosurgical (ON) intervention and endoscopic sinus surgery (ESS) and LOH was significantly shorter for these patients compared to those treated otherwise (14 versus 31 days, p = 0.02). Streptococcus species were the most common group of bacteria identified in 75% of cases, with S. anginosus accounting for 42% of cases. The overall average LOH was 21 days with 92% of patients having complete resolution of symptoms by time of discharge. CONCLUSIONS: Treatment of intracranial complications of acute rhinosinusitis can have favorable outcomes after appropriate surgical management. Localizing neurologic symptoms and seizures portend longer hospital stay and recovery time. Shorter hospital stay was seen in those undergoing early combined ON and ESS interventions.

Management of large scalp and skull defects in a severe case of Adams-Oliver syndrome.

Adams-Oliver syndrome is a rare congenital disorder that includes congenital scalp and skull defects, variable degrees of terminal transverse limb anomalies, and cardiac malformations. Cutis aplasia occurring in 75% of patients is a potentially life-threatening condition. Large skin defects that cannot be closed primarily present a management dilemma, and may require skin grafting or flaps, or a combination of both operative and conservative modalities. The authors' experience in management of huge scalp and bone defects with the Integra Dermal Regeneration Template and regular dressing changes showed good scalp repair and no serious complications attributed to this approach.

Revision surgery for Chiari malformation decompression.

Chiari malformations comprise four different hindbrain anomalies originally described by Hans Chiari, a professor of pathology at the German University in Prague. There are four basic Chiari malformations. The reasons for revision of Chiari malformation decompression may be for conservative or inadequate initial decompression or the development of postoperative complications. Another reason involves cases of both hindbrain herniation and syringomyelia in patients who have undergone adequate posterior fossa decompression without resolution of symptoms, signs, or radiological appearance of their syrinx cavity. Additionally, symptom recurrence has been reported in association with various types of dural grafts. Reoperation or revision surgery for patients with Chiari malformations is common and may not be due to technical error or inadequate decompression. The types of revision surgeries, their indications, and initial presentations will be reviewed.
