 Background: undiagnosed metopic synostosis (Trigonocephaly) have many complications for infant such as Brian damage and cognitive & behavioral disorders also aesthetic malformations.There are a lot of surgical techniques for it that have their advantages and disadvantages but with this new method we can solve some of these problems and minimize damages.

Method:  In this study, 45 infants with Metopicsynostosis underwent surgery in Tehran Mofid Hospital.  The Minimum of age were 4 months  and Maximum 9 months with average of 6.72 months .Our cases in this study are infants with trigonicephaly that their diagnosis is confirmed with clinical symptoms & signs also with CTScan and paraclinical findings. The most common classification of surgical revision of Craniosynostosis  named Whitaker, has been c as follows.

Results: After analysis in this study we find significant differences in anthropometric indeces before & after surgery such as lowering of biparietal width after surgery and elevating of frontoparital index after surgery. As in this procedure, we don’t separate the frontal bone segments and it keeps its frame , so less plaques and screws are needed which will decrease the costs of the surgery and the surgical time is much more fewer than the other techniques.And last but not the least, the satisfactions of parents were high and there was no need for secondary surgery.

Conclusion: Based on all the perfect results we got , it is safe to say that,Staggered osteotomy as a surgical method for correction of trigonocephaly is useful method and we can use it as a new method in correction of  metopic synostosis.
