Background
The surgical approach for cranial reconstruction is influenced by the presence of pre-existing scar tissue. Scars that lie within the vicinity of cranial defect require modification.
Purpose
The present study was conducted to analyse co-relation between craniectomy scar and cranioplasty incision.
Materials and Methods
A retrospective evaluation of 70 patients who were divided into three groups based on location of cranioplasty incision line was done. In group I, incision was located parallel and outside the scar; group II, incision was located over the scar; and group III, mixed and criss-cross incision was present. The primary outcome variable of interest was to analyse co-relation between craniectomy and cranioplasty incisions.
Results
There were 45 cases of group I, 15 cases of group II and 10 cases of group III. Thirty-three patients had defect on left side, 26 had on right side, and 10 had bifrontal defect. No significant association was noted between the site and cranioplasty incision (Chi2 = 9.155, p = 0.433 and likelihood ratio = 9.487, p = 0.394).
Conclusion
Well-vascularized broad-based scalp flap that provides adequate exposure and located on healthy bone irrespective of pre-existing craniectomy scar forms the mainstay of successful cranial reconstruction.
