ENT · Head and neck: maxillary carcinoma staging

Sample item

Ohngren's line used for classification of maxillary sinus carcinoma joins which two points?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

B. Medial canthus and angle of the mandible

Ohngren's line from the medial canthus to the angle of the mandible divides the antrum into an anteroinferior infrastructure and a posterosuperior suprastructure. Tumours of the suprastructure have a worse prognosis because they invade the orbit, ethmoids and skull base.

Option by option

  • A. Nasion and external occipital protuberance

    This line is not a recognised classification.

  • B. Medial canthus and angle of the mandible (correct)

    Correct. The line passes from the medial canthus to the mandibular angle.

  • C. Tragus and ala of nose

    The other points do not define Ohngren's line.

  • D. Zygoma and mental protuberance

    This is not Ohngren's line.
