Outcomes of concurrent endoscopic sinus surgery and rhinoplasty: a case control study.

To evaluate results of concurrent functional endoscopic sinus surgery (FESS) and nasal plastic surgery in terms of safety, efficacy and patient satisfaction, and compare them with the results of single procedures. We conducted a prospective case control study in three groups of patients with chronic sinusitis and nasal deformity; 25 cases had concurrent FESS and rhinoplasty, 25 controls had FESS, and 25 controls had rhinoplasty alone. The patients preoperative and postoperative sino-nasal outcome test (SNOT22) and also patients' satisfaction using the visual analogue scale were evaluated after one year.

Survivin gene polymorphism association with tongue squamous cell carcinoma.

Subject: Survivin expression is correlated with tumor aggressiveness and severity in head and neck carcinoma. A polymorphism at position -31 (G/C) (rs 9904341) has been associated with cancer risk in several studies. We evaluated the correlation of this polymorphism with clinical manifestation of patients with tongue squamous cell carcinoma (SCC) in an Irananian population.
