Objective: The investigation of factors affecting the dimension and configuration of the intranasal ostium in successful external dacryocystorhinostomy (DCR). Material and Methods: Fifty-one patients were enrolled within this study. During operation, dimensions of bone window were measured. In the postoperative sixth month, changes in bone window size were evaluated using spiral paranasal tomography, and the intranasal ostium was examined with nasal endoscopy. Results: There were 19 patients who underwent DCR and 32 patients who underwent DCR+silicone tube intubations (SI). The mean bone window size was 214.37 mm² during operation and 214.87 mm² after six months. The mean intranasal ostium size was measured as 51.42 mm² for patients who had undergone DCR and 28.66 mm² for the DCR+SI cases. The endoscopic appearance of the ostium was observed as oval or round for the DCR cases and in slit form for the DCR+SI cases. A multiple logistic regression model showed that silicon tube intubation posed an 11 times greater risk for configuration distortion in the intranasal ostium (p=0.0079). Conclusion: Postoperative intranasal ostium size has a relation with the intraoperative bone window size. The difference of mean intranasal ostium sizes of DCR and DCR+SI cases was not statistically significant. However, because SI gives rise to ostium configuration by triggering fibrosis, it should not be carried out unless absolutely necessary. [ABSTRACT FROM AUTHOR]

Purpose: To assess the intraoperative frozen section controlled excision method in the treatment of periocular basal cell carcinomas (BCC) and the recurrence rate. Metarial and Method: Records of 30 patients with histological diagnosis of BCC were included in this study. Patients were investigated for demographic information, tumor site and size, histology of tumor, and recurrence rate. The tumor was treated with the frozen section controlled excision method with a 3 mm clear margin in all patients. In cases, where the surgical margins contained tumor cells, further excision was undertaken and eyelid reconstruction was performed at the same session. Postoperatively, histological examination of paraffin sections was done for all patients. Results: The mean age of the 30 patients with primary BCC was 66.1±10.03 (range, 45-82) years. Most BCCs were located at the lower and upper eyelids. In five (16.7%) patients, tumor was detected within the surgical borders after the excision performed under intraoperative frozen section control. In these patients, the excision was extended from the positive margin. Recurrence has not been monitored in any of the patients during the mean follow-up period of 18.46±6.22 (range, 12-36) months. Discussion: We believe that frozen section controlled excision in the surgical treatment of BCC is an effective method for obtaining tumor-free surgical borders and for preventing recurrence.

Five percent (5%) of lacrimal gland tumors are originated from lymphoid tissue. In one type of Hodgkin disease which is abounding in lymphocytes, involvement of lacrimal gland is a rather rare entity. A 48 - year old woman who had swollen both eyelids, applied to department of oculoplasty in our clinic. At inspection, when eyelids were rotated, a mass was seen at the region which fits to bilateral lacrimal gland area. Magnetic resonance imaging of the orbita showed a well-demarcated soft tissue mass without invade adjacent structure in the supero-lateral aspect of the bilateral orbit, occupying lacrimal gland. Lymphadenopathies in abdominal, cervical, inguinal, axillary regions have been found in systemic scanning. Biopsy of lacrimal gland and axillary lymphadenopahty were performed and histopathological examination revealed the diagnosis as Hodgkin disease abounding in lymphocytes. The patient was underwent four cure chemotherapy. Clinical and tomographic findings were found to be regressed after treatment. [ABSTRACT FROM AUTHOR]
