ABSTRACT
Recent studies suggest a relationship between zinc deficiency and inflammation. In the present study, we studied the effect of oral zinc supplementation on clinical improvement of chronic rhinosinusitis with nasal polyposis. In this single-blind randomized controlled trial, 44 patients with chronic rhinosinusitis with polyposis referring to ENT clinic of the Loghman Hakim hospital during 2013-2014 were randomly allocated in two groups. The treatment group (n = 28) was treated with a four-drug fixed-dose regimen (FD_FDR) consisting of oral dexamethasone (0.02 mg/kg), fluticasone nasal spray, fexophenadine 60 mg daily, montelukast 10 mg daily plus 220mg zinc sulfate capsules containing 55 mg elemental zinc, b.d., and the control group (n = 16) received the FD_FDR without supplemental zinc, for six weeks. After sixth week, two groups were compared regarding clinical outcomes based on theSNOT20 (Sinonasal outcome test) questionnaire, the general health questionnaire (SF12), the Lund-Mackay, and the Lund-Kennedy scoring systems. In the treatment group, serum zinc levels were significantly increased compared to those at the baseline (1.33 fold-increase; p = 0.0002). Within groups analysis revealed a significant reduction (p < 0.01) in LM and LK in both treatment (55% LM; 50% LK) and control groups (45% LM; 53% LK). Incontrast, between groups analysis revealed no significant differences in the LM and LK. The treatment group showed a mild superiority in general health improvement compared to that of the control group. Add-on therapy with supplemental zinc sulfate was not associated with significant improvement in patients with chronic rhinosinusitis with nasal polyposis (CRSwNP). The advantage of zinc supplementation on the general health improvement of the patients with CRSwNP requires further assessments.
ABSTRACT
BACKGROUND: Lateral osteotomies are used in rhinoplasty to narrow the nasal bones, close the open roof deformity after hump removal, and achieve symmetry of an asymmetrical framework. But this procedure causes periorbital oedema & ecchymosis. Different techniques have been described for lateral osteotomy. OBJECTIVE: To compare the postoperative ecchymosis and oedema after buccal sulcus lateral osteotomy versus intranasal lateral osteotomy. METHODS AND MATERIALS: In a prospective experimental study, buccal sulcus approach was performed on the right side and an intranasal approach performed on the left side of patients randomly. Then blind analysis of postoperative photographs was performed to determine the incidence of oedema and ecchymosis on each side. RESULTS: Fifty patients were enrolled in the study after exclusion of unfit patients. On the right side (buccal approach osteotomies), a significantly lower incidence of upper and lower eyelid oedema and upper eyelid ecchymosis was seen on both the 2nd day and after 7th day (P < 0.05). The odds ratio of progression of ecchymosis was 2.66 (OR = 2.66, 95% CI: 1.09-5.52, p = 0.048) in intranasal group compare to buccal sulcus group. No significant complication observed. CONCLUSION: The buccal sulcus approach is a safe method for lateral osteotomy with a lower rate of postoperative oedema and ecchymosis and no significant complications.
