Objective: The nasal tip is an important aesthetic feature of the face and its surgery is the most interesting and challenging part of a rhinoplasty. The aim of this study was to evaluate the effect of cutting the depressor septi nasi muscle on the nasal tip rotation and projection. Method: This clinical trial was carried out from 2008 to 2010 in Imam Reza hospital of Tabriz. Forty primary rhinoplasty patients who required nasal tip modifications underwent rhinoplasty including cutting of depressor septi nasi. The nasal tip rotation and projection and patient satisfaction were evaluated before and 6 months after the operation. Results: The mean age of patients was 24.10 ± 5.37 years with male to female ratio of 13/27. Following rhinoplasty including depressor septi nasi muscle cutting, nasal tip rotation and projection, and patient satisfaction were improved in 58%, 70%, and 85% of patients, respectively ( P < .001 for all). Conclusion: Rhinoplasty by cutting and repositioning of depressor septi nasi muscle has effectively improved the nasal tip rotation and projection and patient satisfaction.

Objective: Vocal cord nodules are of the most common benign laryngeal pathologies that may cause dysphonia and hoarseness. This study aimed to assess the effectiveness of surgical versus nonsurgical interventions for vocal cord nodules. Method: In a cohort study, 60 patients with vocal cord nodules were enrolled in 2 groups. The study was carried out from 2010-2011 at Imam Reza Hospital of Tabriz. One group underwent surgical microscopic excision, and the other one was managed with medical and speech therapies. The results were evaluated 3 months later. Results: The mean age of patients was 37.35 ± 9.22 years with male to female ratio of 36/24. In each group, 27% of patients were smokers. Sixty percent of patients in the surgical group had job-related use of voice, compared to 72% in the nonsurgical group. In the surgical group, 63% of patients had bilateral nodules versus 76% in the nonsurgical group. In evaluating improvement of voice quality there was no statistically significant difference between the 2 groups regarding patient satisfaction and the surgeon’s evaluations ( P = .16 and P = .07, respectively). Conclusion: There was no definite difference between surgical and nonsurgical interventions of vocal cord nodules.
