According to the FIGO classification system for submucosal fibroids, which criterion distinguishes Type 1 from Type 2 submucosal fibroids at hysteroscopy?
- A Size of the fibroid: Type 1 is <5 cm, Type 2 is ≥5 cm
- B Proportion of fibroid within the uterine cavity: Type 1 has <50%, Type 2 has ≥50%
- C Proportion of fibroid within the uterine cavity: Type 1 has ≥50%, Type 2 has <50% ✓
- D Location: Type 1 is in the lower segment, Type 2 is in the fundal region
Correct answer: C. Proportion of fibroid within the uterine cavity: Type 1 has ≥50%, Type 2 has <50%
Explanation
The FIGO subclassification of submucosal fibroids (Types 0, 1, 2) is based on the proportion of the fibroid within the uterine cavity versus intramural. Type 1 has ≥50% in the cavity (narrow intramural attachment), Type 2 has <50% (broad intramural attachment). Type 0 is entirely within the cavity. This classification guides resectoscope approach and surgical difficulty.
