# Bone graft absorption complication following cranioplasty: A retrospective institutional study

## TL;DR

This study examines factors related to bone graft absorption after cranioplasty and finds that timing of the surgery affects absorption rates.

## Contribution

The study identifies a specific time window after decompressive craniectomy that increases the risk of bone graft absorption following cranioplasty.

## Key findings

- A cranioplasty performed 2.5-7.7 months after decompressive craniectomy increases the likelihood of bone absorption.
- 116 out of 186 patients who underwent decompressive craniectomy were included in the cranioplasty study.
- The study followed patients for 1 to 10 years post-discharge to assess outcomes.

## Abstract

The aim of the present retrospective study was to confer the factors that are related to bone graft absorption and affect the outcomes of patients following cranioplasty (CPL). The present retrospective study includes cases of patients that underwent CPL between February, 2013 and December, 2022. All participants had a follow-up period of 1 to 10 years from the day of discharge from the hospital. In total, 116 (62.3%) of the 186 patients that underwent decompressive craniectomy (DC) were enrolled in the present study for CPL. A total of 109 (93.9%) patients were included in group A, and 7 (6.0%) patients were included in group B. On the whole, the results of the present study suggest that a CPL after 2.5-7.7 months of DC increases the possibility of bone absorption.
