Latar Belakang : Kranioplasti (CP) merupakan salah satu operasi bedah saraf yang paling sering dilakukan setelah kraniektomi dekompresi (DC). Fungsi CP adalah untuk menempatkan kembali flap tulang yang sebelumnya diangkat saat DC. Rentang waktu antara CP dan DC masih menjadi perdebatan, diakibatkan oleh hasil-hasil yang tidak konsisten antara pemilihan early cranioplasty (EC) dan late cranioplasty (LC). Selain itu, CP dapat disertai dengan berbagai komplikasi, termasuk pembentukan adhesi dan penipisan graft tulang. Berdasakan latar belakang diatas maka peneliti tertarik meneliti tentang rentang waktu operasi (early dan late) kranioplasti autograft paska kraniektomi dekompresi terhadap perlekatan jaringan peridural dan penipisan tulang kalvaria.
Tujuan : Mengetahui hubungan rentang waktu operasi kranioplasti autograft paska kraniektomi dekompresi terhadap perlekatan jaringan peridural intraoperatif dan penipisan graft tulang kalvaria di Rumah Sakit Umum dr. Zainoel Abidin Banda Aceh.
Metode : Sebanyak 10 pasien yang memenuhi kriteria inklusi dan ekslusi dimasukkan kedalam penelitian ini. Penelitian ini menggunakan metodologi analitik cross-sectional. Data derajat perlekatan jaringan peridural dan penipisan graft tulang kalvaria diambil saat operasi kranioplasti oleh dokter spesialis.
Hasil: Berdasarkan uji Chi-Square tidak didapatkan hubungan yang bermakna secara statistik antara rentang waktu operasi dengan derajat perlekatan peridural (p>0,05). Selain itu, Independent T-Test juga tidak mendapatkan hubungan yang bermakna secara statistik antara rentang waktu operasi kranioplasti dengan penipisan graft tulang kalvaria (p>0,05). Meskipun demikian, hasil penelitian ini menunjukkan bahwa EC berkaitan dengan derajat perlekatan yang lebih rendah serta persentase penipisan graft tulang kalvaria yang lebih kecil dibandingkan LC.
Kesimpulan: Tidak ditemukan hubungan yang bermakna secara statistik antara rentang waktu operasi kranioplasti dengan derajat perlekatan peridural maupun penipisan tulang kalvaria. Namun, hasil penelitian ini menunjukkan bahwa EC berkaitan dengan derajat perlengketan yang lebih rendah serta persentase penipisan graft tulang kalvaria yang lebih kecil dibandingkan LC.

Background: Cranioplasty (CP) is one of the most frequently performed neurosurgical operations after decompressive craniectomy (DC). The function of the CP is to reposition the bone flap that was previously removed during the DC. The time span between CP and DC is still a matter of debate, due to inconsistent results between the choice of early cranioplasty (EC) and late cranioplasty (LC). In addition, CP can be accompanied by various complications, including adhesion formation and thinning of the bone graft. Based on those findings, we are interested to investigate the timing for autograft cranioplasty (early and late) after decompressive craniectomy on peridural tissue adhesion and thinning of the calvarial bone. Objective: To investigate the relationship between the timing of autograft cranioplasty surgery after decompressive craniectomy on intraoperative peridural tissue adhesion and thinning of the calvarial bone graft at the General Hospital of dr. Zainoel Abidin Banda Aceh. Methods: A total of 10 patients who met the inclusion and exclusion criteria were included in this study. This study uses a cross-sectional analytical methodology. Data on the degree of peridural tissue adhesion and thinning of the calvarial bone graft were taken during cranioplasty surgery by a specialist. Result: Based on the Chi-Square test, there was no statistically significant relationship between the timing of cranioplasty and the degree of peridural adhesion (p>0.05). In addition, the Independent T-Test also did not get a statistically significant relationship between the timing of cranioplasty and thinning of the calvarial bone graft (p>0.05). Nonetheless, our results show that EC is associated with a lower degree of adhesion and a lower percentage of calvarial bone graft thinning than LC. Conclusion: There was no statistically significant relationship between the timing of cranioplasty and the degree of peridural adhesion and thinning of the calvarial bone. However, our results show that EC is associated with a lower degree of adhesion and a lower percentage of calvarial bone graft thinning than LC.
