Surgery on the frontal sinus or frontal recess remains a challenge for rhinologist because of its variability and complex anatomy. Its location, relatively complex and narrow frontal recess also make visualization difficult and predispose it to stenosis. Significantly, serious complications are possible due to the anterior ethmoidal artery, orbit and anterior cranial fossa. An understanding of frontal sinus and frontal recess anatomy is essential to perform endoscopic frontal sinus surgery. This paper examines frontal sinus anatomy and then variable procedures of endoscopic frontal sinus surgery. The selection of less invasive procedure as possible after assessment of the patient’s history, diagnostic endoscopy, and the CT scan makes successful endoscopic treatment of frontal sinus diseases.

Purpose: A prospective comparison was made between imaging with Tc-99m pertechnetate (Tc-99m) and Ioine-131 (I-131) for the detection of residual and metastatic tissue after total thyroidectomy in patients with well-differentiated thyroid carcinoma. Materials and Methods: Initially our patients had imaging with Tc-99m, followed by I-131 within 3 days. The study included 21 patients who had ablation with high dose of I-131 ranging from 100 mCi to 150 mCi. Planar and pinhole images were acquired for both Tc-99m and I-131. Diagnostic images of Tc-99m and I-131 were compared with post-therapy images. Degree of uptake on Tc-99m and I-131 images was scored by four point scale and compared. Results: The results of the Tc-99m study were: 16 of 19 studies (84%) were positive on simple planar images, but 19 of 20 studies (95%) were positive on pinhole images. Conventional I-131 diagnostic imaging on the other hand showed that all studies (100%) were positive on both planar and pinhole images. There was a significant difference in degree of uptake between Tc-99m and I-131 planar images (p<0.05). Only one case of Tc-99m scintigraphy was negative on both planar and pinhole studies (false negative). There was no distant metastasis on the therapeutic I-131 images. Conclusion: Tc-99m scan using pinhole in certain clinical situations is an alternative to the I-131 scan in detecting thyroid or lymph node metastasis prior to the first ablative treatment after thyroidectomy for well-differentiated thyroid carcinoma.
