Abstract

Purpose

Over the past decade, we collected the cases where patients underwent decompressive cranioplasty for the treatment of mild metopic suture synostosis (mild trigonocephaly) with developmental delays. To evaluate the effectiveness of this surgery, we administered several developmental and psychological examinations to children with this condition who underwent decompressive cranioplasty.

Methods

Thirty-four children (32 boys and 2 girls) who had developmental disorders with mild trigonocephaly underwent four different tests at three different time points (pre-operation, 3 and 6 months after surgery) including the: (a) Kyoto form developmental test (2001) to calculate the developmental quotient (DQ), (b) National Rehabilitation Center Sign-Significance Test (NRC S-S test) to evaluate the patients’ language use and acquisition, (c) Pervasive Developmental Disorders Autism Society Japan Rating Scale (PARS) to identify autistic tendencies, and (d) Japanese Child Behavior Checklist (J-CBCL) to evaluate behavioral problems. The scores were initially analyzed using analyses of variance. When significant results were observed, Tukey–Kramer multiple comparison tests were applied for further statistical evaluation.

Results

Significant DQ improvements were observed, as assessed by the Kyoto form developmental test. Additionally, significant improvement in the expression of words (measured with the NRC S-S test), the scores on PARS, and some behavioral factors (measured with the J-CBCL) were observed.

Conclusions

The results in this cohort suggest that decompressive cranioplasty may play an important role in supporting the improvement of developmental delays in these patients.
