Disorders of the lacrimal drainage system are, at the least, very annoying to the patient and when serious infection is present may threaten vision and life. The definitive treatment for most lacrimal drainage system is surgical. Dacryocystorhinostomy (DCR), a procedure that fistulizes the lacrimal sac and nasal cavity, is the most frequency lacirmal drainage surgery. Indications for DCR include acquired nasolacrimal duct obstruction with patent canaliculi or this condition combined with a distal common canalicular obstruction, persistent nasolacrimal duct obstruction following probing and intubation, chronic dacryocystitis, and lacrimal sac foreign bodies. The only absolute contraindication is malignancy of the lacrimal sac, which is treated by dacryocystectomy. The patient, 55-year-old male, was admitted with the complaints of pus discharge from the medial commissure on the Rt. eye and oro-antral fistula on the Rt. maxillary sinus. In the past history, Caldwell-Luc operation was performed on the Rt. maxilla about 2 years before for the management of oroantral fistula. He was diagnosed as dacryocystitis with nasolacrimal duct obstruction and oro-antral fistula, and treated by dacryocystorhinostomy and Caldwell-Luc operation under general anesthesia. The postoperative course was unremarkable and the patient has been well for over 1 year postoperatively.

This study was performed to evaluate the effects of preoperative and postoperative radiation on the healing of surgical wound and the relationship between surgery-radiation interaval histopathologically. Experimental animals were 64 rats of Sprague-Dawely strain weighing about 180grams. In postoperative radiation group, a single dose of 100 rads irradiation was delivered on 1,2,3, weeks after incision and 24 animals were sacrificed on the 1st, 3rd, 7th, and 14th dat after radiation. In preoperative radiation group incision was performed on 1,2,3,4 weeks after a single dose of 1000 rads and 32 animals were sacrificed on the 1st, 3rd, 7th, and 14th after incision. Tissue specimens were prepared as usual methods and stained with hematoxyline-eosin for ordinary light microscopy. Histopathologic study revealed the following favorable results : 1. In 2 and 3 weeks radiation group after incision, the healing process was unaffected by radiation. 2. In 1 week radiation group after incision, the healing process was slightly retarded, as compared with 2,3 weeks radiation group after incision. 3. In 1,2 and 3 weeks incision group after radiation, the healing process appeared about 7 days later than that of control group. 4. In 4 weeks incision after radiation, the healing process was unaffected by radiation.
