The author, since 1969, has established and had experience with an ideal antral window operation as a simple type of intranasal surgery using a double flap mucous-plasty in the treatment of chronic maxillary sinusitis. This intranasal antrostomy with nasoantral windowplasty is an ideal technique in sinusitis cases with mildly infamed and reversible conditions, without polypoid and highly thickened mucosa of the maxillary antrum, and has provided satisfactory surgical results with the following advantages:
1. It prevents the postoperative occurrance of unpleasent complications such as cheek swelling, dental and labial numbness, obstruction of the nasolacrimal passage due to over-curettage, osteomyelitis and postoperative cheek cyst as in cases following radical surgery.
2. The technique of two mucosal flaps taken from the nasal cavity and the maxillary antrum covers the up- and down-margin of the window and can prevent postoperative bony bleeding and reclosing of the window due to over-granulation, and consequently can keep the nasoantral window permanently open for free drainage.
3. The operation is very simple and conveniently performed under local anesthesia and requires minimal hospitalization.
4. There is minimal reaction, and minimal injury to the mucosa which rapidly returns to normal function.
5. High antroscopic visibility, to determine the status of the antral interior at all times during the surgery and the postoperative treatment, is provided.
6. In consideration o. excretory function, ventilation and directional ciliary beating of the antral mucoua, the author believes that this intranasal antrostomy with nasoantral windowplasty is ideal and a better procedure than other simple antrostomies and better than Boenninghaus´s single flap-plasty in the choice of different plastic techniques of the mucosal flap, and also this operation can proceed to a radical antral procedure.
