A new technique for correction of trigonocephaly in an infant: applicationof an absorbable endocranial plate

We report on a new method of cranial bone osteofixation using absorbable ma terial, which is applied endocranially to avoid the application of a thick, cosmetically inferior system epicranially in the frontal area. This is esp ecially important in the correction of deformity in trigonocephaly cases. A 9-month-old boy presented with a prominent trigonocephalic deformity. Cran ioplasty was performed, in which a supraorbital bar (bandeau) was removed, reinforced with a self-reinforced polylactide (SR-PLA) plate and reshaped t o correct the deformity. The plate was applied on the inner side of the bon y bar, with its ends fixed epicranially to the temporal bones by means of S R-PLA miniscrews. 3-D CT scans and rapid prototypes were used to evaluate t he results. Stable and secure fixation was obtained, and the cosmetic resul t appeared excellent. No complications occurred during the postoperative pe riod of 1 year. Hence, stabilisation of cranial bone can be achieved endocr anially using an absorbable plate and screws, with an encouraging cosmetic result. The method is thought to be reliable.
