The Snails: A Simple Technique for Reduction of Frontal Bossing in Children With Scaphocephaly.

OBJECTIVE

Scaphocephaly represents the most frequent single-suture craniosynostosis, with a male prevalence. In many cases, prominent frontal bossing (sphenocephaly) is the major aesthetic concern, typically in school-aged children. This aspect is also usually found in patients with late presentation (after 1 year of age). Several techniques have been described for the correction of frontal bossing in these patients, most involving wide frontal bone exposure and reconstruction. The authors describe a different, less invasive technique, useful in severe sphenocephalic patients, independently from age.

METHODS

Thirteen children aged from 3.5 to 22 months were operated on in our institution between 2016 and 2023 using the snails technique, in addition to the treatment for the craniosynostosis itself. The technique is described, consisting in spiral frontal impacted craniotomies. Transfusional rate and duration of surgery are reported and compared with 15 randomly selected patients treated at the same time without Snails technique. Postoperative follow-up is almost 1 year.

RESULTS

Cosmetic postoperative results, based on parental and clinician's satisfaction as well as on radiographic and photographic assessment, showed rapid improvement of frontal bossing, which remains stable during years. Transfusion rate during scaphocephaly repair with Snails technique is not different from control, even if time of procedure is longer.

CONCLUSION

Among several techniques described to directly correct frontal bossing, the snail technique is more simple and less invasive, avoiding further craniotomies over the superior sagittal sinus, and does not imply consistent blood loss.
