Distraction osteogenesis in craniosynostosis

PURPOSE OF REVIEW

Craniosynostosis, a condition of premature cranial suture fusion, can have significantly detrimental effects on development and growth due to sequelae of increased intracranial hypertension (ICP), exophthalmos, and upper airway obstruction. Evolving surgical treatments now include distraction osteogenesis (DO) due to its many benefits relative to standard cranial vault remodeling procedures. This article provides an overview and update of different surgical applications of DO for patients with craniosynostosis.

RECENT FINDINGS

DO has been utilized successfully for single and multisuture craniosynostosis with or without midface hypoplasia to increase intracranial volume, decrease ICP and improve aesthetics. It has been applied in single suture synostosis, posterior vault DO, fronto-orbital advancement, monobloc DO and Le Fort III DO. DO has been applied through modification of traditional surgical procedures with success in maintaining goals of surgery while reducing risk.

SUMMARY

DO is still a relatively new and evolving surgical technique for patients with syndromic and nonsyndromic craniosynostosis. With promising benefits, consideration for each procedure should be weighed until longer-term data is available.

Posterior vault distraction technique: how I do it

Posterior cranial vault distraction is an effective technique when a significant increase in the intracranial volume is required in patients with craniosynostoses. This technique has been proven to be safe and time saving and usually is associated with low perioperative morbidity as well as low intraoperative bleeding. Herein a technique is presented starting from the preoperative planning, describing the surgical steps of the operation and the postoperative distraction protocol used by the authors. The authors present important tips and tricks aiming to minimise complications and undesired events.

Distraksiyon ostegenizisi ve maksillofasyal bölge güncel uygulamaları :derleme

Distraksiyon osteogenezisi kallusu gererek yeni kemik oluşturma tekniğidir. Bu teknik ilk olarak Rus bilim adamı ortopedist İlizarov tarafından uzun kemiklerde geliştirilmiştir.Distraksiyon osteogenezisi; osteotomi periyodu, latent periyod, distraksiyon periyodu ve konsolidasyon periyodu olmak üzere 4 safhadan oluşmaktadır. Kolay, etkili ve komplikasyonu az olan bir uygulamadır. Distraksiyon osteogenezisi, maksillofasiyal cerrahide yaygın olarak kullanılabilmesi için modifikasyonlara ve geliştirmelere ihtiyaç duyulan bir tekniktir. Distraksiyon osteogenezisi tekniğinin gelişmesi için materyal ve teknik olarak birçok araştırma yapılmıştır ve birçok gelişme kaydedilmiştir. Ancak bu araştırmalar henüz tam bir kesinlik kazanmamakla beraber olumlu sonuçlar vermektedir
