    AIM: Anterior plagiocephaly usually occurs with premature synostosis of the ipsilateral half of the coronal suture. The forehead is flattened on the affected side, with a backward and upward displacement of the affected orbit. The bulging of the calvaria may occur in the contralateral parietal area. MATERIAL and METHODS: This article presents the surgical techniques used over 7 years to treat plagiocephalic children. Eleven patients with unilateral coronal synostosis treated during 2003-2010 were analyzed retrospectively. The study included reviews of pre and postoperative computed tomography scans, operative techniques, clinical outcomes and complications. Unilateral orbital advancement with ``tongue in groove{''} was performed in 5, and bilateral orbital advancement in 6 cases. Pre and postoperative anthropometric measurements were used to document the amount of advancement of the elevated and recessed orbita, and the amount of withdrawal of the contralateral side. RESULTS: The mean age of the patients at time of surgery was 11 months. The preoperative values of the orbital height and retrusion were 0.68 cm and 1.87 cm, respectively. They were recorded as -0.1cm and 0,63 cm, postoperatively. Mean follow-up was 36 months, neither neurological sequelae nor other significant complications were encountered. CONCLUSION: The surgical corrections have resulted in significant improvements in skull shape and high patient/parent satisfaction.

    Concurrent Repair of Orbital Shallowness with Craniosynostosis Surgery: Two Late Cases of Simultaneous Orbital Decompression
    (TURKISH NEUROSURGICAL SOC, 2013-01-01) Oreroglu, Ali Riza; Silav, Gokalp; Ozkaya, Ozay; Orman, Cagdas; Akan, Mithat
    Early closure of cranial sutures results in various types of cranial vault deformities, named craniosynostosis. Although mostly associated with syndromic cases, bony orbit deformities such as exorbitism can be seen with various types of craniosynostosis. This condition can be associated with papilledema and besides its effect on the patient's appearance can cause subluxation of the globe, lagophthalmos or keratitis resulting in corneal ulcers and ultimately loss of vision. Various techniques have been proposed for repair or exorbitism such as fronto-orbital advancement procedures, orbital wall decompression, periosteum scoring and tissue excision. Orbital periosteal scoring covering the globe can be extremely efficient for orbital fat decompression when combined with other orbital volume expanding procedures. We hereby present two late cases of craniosynostosis associated with bilateral exorbitism due to orbital shallowness for which cranial vault reconstruction was performed simultaneously with combinations of fronto-orbital advancement, orbital decompression and periosteal scoring. The late referral of these patients at ages older than the usual time of operation indication made the surgical procedure for craniosynostosis repair and exorbitism treatment challenging. The combined and simultaneous use of bone advancement, orbital wall decompression and specially periosteum scoring can be highly efficient in the treatment of exorbitism associated with craniosynostosis.
