An Esthetic Scoring System for Scaphocephaly Assessment and Outcomes: A Pilot Study.

Scaphocephaly is the commonest form of craniosynostosis with a varied presentation consisting of many morphological components and a range of possible surgical interventions. However, with regard to esthetic assessment, there is no universally applied assessment system. The aim was to develop a simple assessment tool encompassing multiple phenotypic components of scaphocephaly. This was done by piloting a red/amber/green (RAG) scoring system to judge esthetic outcomes following scaphocephaly surgery using photographs and experienced observers. Standard photographic views of 20 patients who had undergone either passive or anterior 2/3 vault remodelling were scored by 5 experienced assessors. Using a RAG scoring system before and after scaphocephaly correction according to 6 morphological characteristics: visual impression of cephalic index, calvarial height, bitemporal pinching, frontal bossing, posterior bullet, and displacement of the vertex. All 5 assessors were asked to score the preoperative and postoperative views independently. The RAG scores were each assigned a number (1-3) and added to give a composite score (range 6-18) and these were averaged between the 5 assessors. There was a highly statistically significant difference between both preoperative and postoperative composite scores ( P <0.0001). A subgroup analysis of the postoperative composite score between the 2 surgical techniques showed no significant difference ( P =0.759). The RAG scoring system can be used to assess esthetic change following scaphocephaly correction and it provides both a visual analogue and a numerical indicator of change. This assessment method needs further validation but is a potentially reproducible way to score and compare esthetic outcomes in scaphocephaly correction.
