Abstract

Purpose: This study aimed to investigate the morphometric structure of the foramen ovale (FO) and foramen rotundum (FR) through Computerized Tomography (CT) images of individuals diagnosed with trigeminal neuralgia (TN) without any vascular compression.

Materials and Methods: The study was approved by the Tokat Gaziosmanpaşa University Clinical Research Ethics Committee on March 2, 2023, with approval number 83116987-143. Thirty-four patients (16 males, 18 females) diagnosed with Trigeminal Neuralgia (TN) at the Clinic of Neurology, Tokat Gaziosmanpaşa University Faculty of Medicine, and 34 individuals (15 males, 19 females) selected as the control group (CG) were retrospectively analyzed. CT images of all participants were obtained in the coronal, sagittal, and transverse planes using the Horos software. Plane adjustments were applied to these images, referred to as modified planes, for morphometric measurements.

Results: There was no significant difference in the mean length and width measurements of the FO between individuals with TN and the CG on the side with nerve involvement (p>0.05). The mean length and width measurements of the FR on the affected side in the trigeminal neuralgia group (TNG) were significantly smaller when compared to the CG (p<0.001). It was found that increasing age significantly affected nerve involvement on the right side (p=0.005).

Conclusion: We believe that knowledge of the morphology of FO and FR would contribute to clinicians in the diagnostic and interventional treatment approaches of TN.

Trigeminal Nevralji Hastalarında Foramen Rotundum ve Foramen Ovale’nin Morfometrik Olarak İncelenmesi

Abstract

Amaç: Bu çalışmanın amacı, herhangi bir vasküler bası olmaksızın trigeminal nevralji (TN) tanısı alan bireylerin Bilgisayarlı Tomografi (BT) görüntüleri aracılığıyla foramen ovale (FO) ve foramen rotundum'un (FR) morfometrik yapısını araştırmaktır.

Araçlar ve Yöntem: Çalışma, Tokat Gaziosmanpaşa Üniversitesi Klinik Araştırmalar Etik Kurulu, 02.03.2023 tarihinde 83116987-143 sayılı kararla onaylandı. Tokat Gaziosmanpaşa Üniversitesi Tıp Fakültesi Nöroloji Kliniğinde TN tanısı almış 34 hasta (16 erkek, 18 kadın) ile kontrol grubu (KG) olarak belirlenen 34 olgu (15 erkek, 19 kadın) retrospektif olarak incelendi. Tüm bireylerin BT görüntüleri Horos programı kullanılarak koronal, sagittal ve transvers düzlemlerde elde edildi. Elde edilen görüntüler üzerinde düzlem düzeltmeleri yapıldı ve bunlar modifiye düzlemler olarak adlandırıldı. Morfometrik ölçümler modifiye edilmiş düzlemler üzerinde gerçekleştirildi.

Bulgular: TN'li bireyler ile sinir tutulumu olan taraftaki KG arasında FO'nun ortalama uzunluk ve genişlik ölçümlerinde anlamlı bir fark yoktu (p>0.05). Trigeminal nevralji grubunda (TNG) etkilenen taraftaki FR'nin ortalama uzunluk ve genişlik ölçümleri KG'ye kıyasla anlamlı olarak daha küçüktü (p<0.001). Artan yaşın sağ taraftaki sinir tutulumunu anlamlı olarak etkilediği bulundu (p=0.005).

Sonuç: FO ve FR morfolojisinin bilinmesinin TN'nin tanısal ve girişimsel tedavi yaklaşımlarında klinisyenlere katkı sağlayacağına inanıyoruz.
