I have found the two instruments illustrated in the sketch practical and useful in resection of the antrum window. They can be used in either the simple or the radical types and are especially adapted to breaking down thick naso-antral walls.
The anterior bone resector has proved indispensible, as it easily and rapidly breaks down the naso-antral bony wall in a forward direction. This is accom Instrument for resecting the antrum window A, anterior bone resector; B, posterior bone resector.
plished by perforating the naso-antral wall posteriorly with a Wellamenski's antrum perforator, or other suitable instrument, and engaging the bone in the embrasure of the bone resector. By a twisting and rotary motion of the handle, the wall is readily broken down in a forward direction.
The posterior bone resector is not so useful but may be helpful when working space is limited. At Dr. C. Armin Gundelach's suggestion,
