Abstract

Aim: In this study, we aimed to investigate the relationship between sphenoid sinus pneuma¬tization and the angle of the Eustachian tube.

Methods: The study included a total of 158 patients. The Eustachian tube angle (ETA) was measured and sphenoid pneumatization was classified in the coronal plane.

Results: According to the coronal classification of sphenoid pneumatization, 52 (16%) hemi-sphenoids were type 1, 177 (56%) hemi-sphenoids were type 2, and 87 (27.5%) hemi-sphe¬noids were type 3. According to the sagittal classification, 24 (7.6%) hemi-sphenoids were pre-sellar, 101 (32%) hemi-sphenoids were sellar, and 191 (60.4%) hemi-sphenoids were post-sellar. The mean ETA in coronal classification was 24.71±3.35, 25.03±3.24, and 25.90±3.10 de¬grees for the type 1, type 2, and type 3 classes, respectively. The angle showed a gradual increase from type 1 to type 3, and it was found that ETA was statistically significantly wider in cases with lateral recess pneumatization (type 3, post-rotundum) than in type 2 and type 1 pneumatizations (p=0.039, p=0.035, respectively).

Conclusion: ETA is increased in patients with lateral recess pneumatization.

Sfenoid Sinüs Pnömatizasyonu Östaki Tüpü Açısını Etkiliyor mu?

Abstract

Amaç: Bu çalışmada sfenoid sinüs pnömatizasyonu ile Östaki tüpünün açısı arasındaki ilişkiyi araştırmak amaçlanmıştır.

Yöntem: Çalışma toplam 158 hasta içerdi. Östaki tüpü açısı (ÖTA) ölçüldü ve sfe¬noid pnömatizasyonu koronal planda sınıflandırıldı.

Bulgular: Sfenoid pnömatizasyonunun koronal tasnifine göre 52 (%16) hemi-sfenoid tip 1, 177 (%56) hemi-sfenoid tip 2 ve 87 (%27,5) hemi-sfenoid tip 3 idi. Sagital tasnife göre 24 (%7,6) hemi-sfenoid pre-sellar, 101 (%32) hemi-sfenoid sellar ve 191 (%60,4) hemi-sfenoid post-sellar idi. Koronal tasnifte ortalama ÖTA tip 1, tip 2 ve tip 3 sınıfları için sırasıyla 24,71±3,35; 25,03±3,24 ve 25,90±3,10 derece idi. Açı tip 1’den tip 3’e kademeli olarak artış gösterdi ve ÖTA’nın lateral reses pnömatizasyonlu hastalarda (tip 3, post-rotundum) tip 2 ve tip 1 pnömatizasyonlara kıyasla istatistiksel olarak anlamlı biçimde daha geniş olduğu tespit edildi (sırasıyla p=0,039; p=0,035).

Sonuç: Lateral reses pnömatizasyonlu hastalarda ÖTA artmaktadır.
