Mandibuladaki geniş kistik lezyonların hacmi ile dekompresyon süreleri arasındaki korelasyon: retrospektif KIBT çalışması

Amaç: Bu çalışmada mandibuladaki geniş kistik lezyonların dekompresyon sonuçlarının retrospektif olarak değerlendirilmesi, dekompresyon süreleri ile lezyonların konik ışınlı bilgisayarlı tomografi (KIBT) ile ölçülen başlangıç hacimleri arasındaki korelasyonun analiz edilmesi amaçlanmıştır. Gereç ve Yöntem: Bu retrospektif çalışma tek bir geniş kistik lezyon nedeniyle dekompresyon tedavisi uygulanan 13 hastadan oluşmaktadır. Tüm kistik lezyonlar anterior ile ramus mandibula arasında yer almaktadır. Tüm kistik lezyonlar sadece dekompresyon yöntemi ile tamamen iyileşmiştir. Lezyonların hacimleri KIBT ile ölçüldü. Dekompresyon, kişiye özel akrilikten imal edilen stentlerin kistik kaviteye yerleştirilmesi ile gerçekleştirildi. Dekompresyon periodu ile başlangıç KIBT hacimleri karşılaştırıldı. Bulgular: Ortalama yaş 39.85 yıl, ortalama dekompresyon süresi 12.38 ay, ortalama takip süresi 20.15 ay ve ortalama başlangıç KIBT hacmi 7076.81 mm3 idi. Kistik lezyon hacmi ile dekompresyon periodu arasında pozitif korelasyon olduğu bulundu. Sonuç: Dekompresyon yöntemi uyumlu hastalarda geniş kistik lezyonların tedavisinde faydalı sonuçlar sağlayabilir, non-invaziv cerrahi, kemik kırığı ve inferior alveolar sinir yaralanması gibi ciddi komplikasyon ve morbidite risklerinin azaltılması gibi çok sayıda avantaj sağlar. Ancak odontojenik keratokist ve ameloblastoma gibi agresif kistik lezyonlarda dekompresyonu takiben cerrahi tavsiye edilmektedir.

Correlation between decompression period and initial volume of large cystic lesions of the mandible: a retrospective CBCT study

Purpose: The aim of this retrospective study was to evaluate the outcomes of the decompression of large cystic lesions of the mandible and to analyze the correlation between decompression period and the cone-beam computed tomography (CBCT) volume of initial lesions.Materials and Methods: The retrospective study included 13 patients who underwent decompression due to single cystic lesions. All the cystic lesions were localized in the mandible, between the anterior region and the ramus region. All the lesions recovered completely via decompression alone. Volume of the lesions was measured with CBCT and decompression was conducted with a customized acrylic resin stent inserted in the cystic cavity. Decompression period and initial CBCT volume were compared.Results: Mean age of the patients was 39.85 years, mean decompression periods was 12.38 months, mean follow-up period was 20.15 months, and mean initial CBCT volume was 7076.81 mm3. A positive correlation was found between the volume of the cystic lesions and the decompression period.Conclusion: Decompression can provide useful outcomes in the treatment of large cystic lesions in compatible cases since it provides numerous advantages such as noninvasive surgery, low risk of morbidity and severe complications such as bone fracture and inferior alveolar nerve injury. However, in aggressive cystic lesions such as odontogenic keratocyst and ameloblastoma, subsequent definitive surgery following decompression is recommended.
