Abstract

AIm: Surgical approaches to Meckel’s cave (MC) are often technically difficult and sometimes associated with postoperative morbidity. The relationship of surgical landmarks to relevant anatomy is important. Therefore, we attempted to delineate quantitatively their anatomy and the relationships between MC and surrounding structures. MaterIal and Methods: With the aid of a surgical microscope, MC and its contents were studied in 15 formalin-fixed cadaver head specimens. Measurements were made and their relationships were observed. Results: The distance from the zygomatic arch and the lateral end of the petrous ridge to MC was 26.5 and 34.4 mm, respectively. The distance from the arcuate eminence, the facial nerve hiatus, and the foramen spinosum to MC was 16.6, 12.8 and 7.46 mm respectively. The TG lay 5.81 mm posterior to the foramen ovale. The distance from the abducens, trochlear and oculomotor nerves to the trigeminal ganglion was 1.87, 5.53 and 6.57 mm respectively. The distance from the posterior and the anterior walls of the sigmoid sinus to the trigeminal porus was 43.6 and 33.1 mm respectively. The trigeminal porus was on average 7.19 mm from the anterior wall of the internal acoustic meatus. ConclusIon: The anatomical landmarks as presented herein regarding MC may be used for a safer skull base approach to the region.

Özet

AMAÇ: Meckel cave cerrahi yaklaşımları teknik olarak zordur ve sıklıkla ameliyat sonrası komplikasyonlarla birliktedir. Cerrahi belirteçlerin ilgili anatomiyle ilgisi önemlidir. Bundan dolayı, biz onların anatomisini ve çevre yapılarla ilişkilerini tanımlamaya çalıştık. YÖNTEM ve GEREÇLER: Cerrahi mikroskopun yardımıyla, Meckel cave ve onun ihtivası formalinle fikse olmuş 15 kadavra başında çalışıldı. Ölçümler yapıldı ve ilişkileri gözlendi. BULGULAR: Zigamatik arkusun ve petroz kenarın lateral sonunun Meckel cave’e ortalama uzaklığı sırasıyla 26,5 ve 34,4 mm idi. Arkuat eminens, fasiyal sinir hiatus ve foramen spinosumun Meckel cave’e ortalama uzaklığı sırasıyla 16,6, 12,8 ve 7,46 mm idi. Trigeminal ganglion foramen ovale’nin 5,81 mm arkasında yerleşmiştir. Abdusens, trohlear ve okülomotor sinirlerin trigeminal gangliona ortalama uzaklıkları sırasıyla 1,87, 5,53 ve 6,57 mm idi. Sigmoid sinüsün arka ve ön duvarlarının trigeminal porus’a ortalama uzaklıkları sırasıyla 43,6 ve 33,1 mm idi. Trigeminal porus internal akustik meatusun anterior duvarından ortalama 7,19 mm uzakta idi. SONUÇ: Meckel cave ile ilgili sunulan anatomik belirteçler ve onların anatomik özellikleri ile ilgili bilgiler bu bölgeye güvenli bir yaklaşım için yararlı olabilir.
