Mitomycin-C and Co2 laser cordectomy

This study was conducted on 19 patients with bilateral abductor paralysis. They were divided into 2 groups. In group A [9 patients], posterior cortectomy with Co2 laser was done. In-group B [10 patients], mitomycin c [MMC] was applied locally at the site of cortectomy. The recurrence rate of stridor was about 55.5% in-group A and 10% in-group B, after following the patients for one year. The resu1ts encourages the use of MMC with posterior cortectomy to improve it's results

Comparative study between two methods of endoscopic endonasal dacryocystorhinostomy [surgical and office-based laser-assisted]

In this work, a comparison was made between the endoscopic endonasal surgical dacryocystorhinostomy [EES-DCR] and the endoscopic endonasal office-based laser-assisted dacryocystorhinostomy [EEOL-DCR]. A number of modifications were applied in the laser-assisted technique to improve its lower success rate reported in the literature. The results concerning EEOL-DCR were satisfactory and comparable to some extent to the EES-DCR results. It was concluded that the EEOL-DCR is a safe, effective and rapid procedure that could be done under local anesthesia as an office-based technique. It was indicated for selected cases as in patients with bleeding disorders and anticoagulated patients as well as in patients in whom general anesthesia is difficult or contraindicated or in revision cases after external DCR
