Long-term results of combined approach in parotid sialolithiasis.

Combined sialendoscopic and transcutaneous approach in parotid sialolithiasis is a surgical option for large and impacted stones. The aim of this study is to assess the long-term results regarding postoperative stenosis, recurrent swellings and gland function. Prospective study in a tertiary referral center of patients with parotid sialolithiasis requiring combined approach. A total of 12 patients have been treated within a period of 3 years. Intraductal stents were placed in 9 of 12 cases. Scintigraphic evaluation of salivary glands and follow-up sialendoscopy performed 1 year postoperatively. In total, fourteen stones (two stones in two cases) were successfully removed along with two coexisted inflammatory polyps. Postoperative endoscopic evaluation revealed mild stenosis in 7 out of 12 cases without clinical significance as no recurrent swellings were reported. Scintigraphy showed normal gland function in 11 cases and mild hypofunction in 1 case with long-standing history of sialolithiasis. All patients were free of symptoms within the follow-up period of time (median follow-up 15.5 months). Combined approach is a safe, gland preserving and efficacious procedure in long term. The stenosis in the area of ductal surgical opening when present does not seem to be of clinical value.

A novel technique for mitomycin-c application in frontal sinus surgery.

OBJECTIVE: Local application of mitomycin-c (MMC) seems to be effective in reducing adhesions and stenosis after FESS. However this is not clearly seen in frontal sinusotomy. This study assesses the effectiveness of local MMC in the frontal ostium using a foamy material (otowick) and compared with cottonoids. METHODS: Forty-seven patients with chronic rhinosinusitis without polyps enrolled in this study. Two subgroups were studied: one with MMC application in one nostril using cottonoids and a second with MMC injected in an otowick. In all patients MMC was applied twice, intraoperatively and 4 weeks later. In both groups normal saline was applied to the other nostril on the same material with the MMC side. Six months postoperatively all patients were assessed endoscopically by a clinician blinded to the MMC side. RESULTS: Overall, MMC application was more effective than normal saline in both groups. Otowick use presented favorable initial results especially in primary cases regarding ostium patency, and need for revision surgery. The use of MMC cottonoids did not show any benefit in primary cases. CONCLUSION: The described technique seems to be effective in maintaining frontal ostium patency as it provides a more precise and deeper drug delivery to this area.
