title: [Improved depth exposure for monocular anterior rhinoscopy with the fiber optic headlight reflector].
abstract: The usual position of the light reflector of the fiberoptic headlight over the nose of the physicians allows exposure of only the anterior half of the depth of the nose. This limitation is due to the distance between the visual axis and the axis of light. A simple rotation of the reflector towards the dominant eye of the physician decreases the distance between these axes. This allows exposure of structures within the entire nose and into the nasopharynx. This technique not only facilitates diagnostic assessment but also improves postoperative care after endonasal surgery.
