  • Abstract
  • Look Inside

 A new slender type of endoscope is used for visualization of the tympanic membrane and inside of the maxillary sinus.

 This scope is made of special rod lens (Selfoc).The Selfoc rod lens of 1.0 mm diameter is covered with glass fiber for illumination. The outer diameter of scope is only 1.7 mm. At present, two types of the scope are available : straight view type and anterior oblique type. This Selfoc scope is so slender that it can hardly be harmful.

 Good candidates for ear scopy are those with the stenotic external canal. For inspection of the maxillary sinus, a trocar of 2.0 mm diameter is stabbed through the medial wall of the maxillary sinus at the inferior nasal meatus. Photography is easily taken using a powerful light source.
