Evaluation of the Results of Septum Extension Batten Graft in Patients Referred for Septorhinoplasty.

 Correction of caudal septal deviations has always been a challenging subject in septorhinoplasty. The septum batten extension graft (SBEG) is a new graft that has potential properties in rhinoplasty. However, few reports have evaluated the surgical outcomes of this technique.  The purpose of this study was to evaluate the effectiveness of SBEG in correcting caudal septal deviation.  This cross-sectional study was conducted on patients with caudal septal deviation undergoing septorhinoplasty using SBEG at 2 different hospitals in 2019. We then retrospectively reviewed medical records and photographs of 50 patients at the preoperative period, as well as at 1-month, and 12-month postoperatively. Gross changes in nasolabial angle, columellar show, nasal tip projection, and dorsal nasal deviation were evaluated by a photographic analysis method, and nasal obstruction was assessed by patient satisfaction with breathing.  There was a significant difference between the mean nasolabial angle and columellar show at 1 and 12-months postoperatively, compared with the previous values (  < 0.0001). The nasolabial angles were in a favorable position with an increase of 12 to 15 degrees compared with the preoperative state. The columellar show also improved by an average of 1.2 mm and was in good condition. The postoperative dorsal nasal deviation was significantly reduced, and projection was significantly increased (3.521 ± 0.087 mm vs. 0.719 ± 0.028;  < 0.0001;  < 0.001). Moreover, this method had a significant favorable effect on nasal obstruction (  = 0.049).  Our results showed that septorhinoplasty using SBEG is useful for correcting caudal septal deviation, with favorable surgical outcomes, and it has responded well to all five aforementioned criteria.
