    Abstract:
    Deviated cartilages structures of the nose can be affected by nasal muscles, and deviation becomes conspicuous when the patient smiles. This condition depends on activity of nasal muscles, particularly the levator labii alaeque nasi muscle. A total of 124 septorhinoplasty operations were performed to correct dorsal concave septal deviation between 2005 and 2009 years. The 70 women and 54 men included in the study had an average age of 28 years. The average follow-up period was 12 months. Open septorhinoplasty was preferred in all cases. The medial part of the levator labii alaeque nasi muscle was extensively dissected from the lateral crus and surrounding tissues. The lateral crura of the alar cartilages were separated from the upper lateral cartilages in the scroll area. The dorsal septal deviation was corrected by combination of bilateral spreader grafts, which reinforced cartilage with horizontal control sutures. Early postoperative period was uneventful. Nasal obstruction was reduced after surgery, and significant subjective postoperative improvements were observed in all patients. Comparison of preoperative and postoperative photographs demonstrated improved dorsal nasal contour. Revision operation was performed in 3 cases. The corrected septal cartilage was in a good position in all revised cases; therefore, septal surgery was not performed in the revision operations. In conclusion, surgical disruption of the anatomic relationship between the muscle with the dorsal septal cartilage and reinforcement of the dorsal septal cartilage with spreader grafts and horizontal control sutures can decrease risk of recurrence.
