Abstract

Nasal tip support is critical to achieve a lasting result in rhinoplasty. In this article, the authors compared the effects of strut grafts (SG) and caudal septum-based nasal tip supporting techniques (CSB-T) in terms of reaching the desired tip projection.

Included in this study were 40 patients (24 women and 16 men) who underwent primary open rhinoplasty via transcolumellar incision between January and June 2012. To achieve a good nasal projection, SG and CSB-T were used for 15 and 25 of these patients, respectively.

Certain anatomic landmarks were identified on preoperative, simulative, and 1-year follow-up photos. With these landmarks, certain angular and proportional values were calculated.

In the SG, the authors found no statistically significant difference in between simulative goals and postoperative results regarding bending angle. Postoperative nasolabial angle (NLA), tip angle, subnasal-tip/subnasal-radix (SnT/SnR) ratios were significantly lower than the simulation values; radix angle and supratip index values were significantly higher.

In the CSB-T group, the authors found no statistically significant difference in between preoperative values and postoperative results regarding NLA, tip angle, bending angle, (SnT/SnR) ratio values. Postoperative supratip index and radix angle measurements were found to be significantly higher than the simulation values.

With these findings, the authors concluded that CSB-T support is superior than the SG for supporting the nasal tip in noses that also need shortening in caudal length. In noses that do not need caudal shortening, nasal tip projection can again be supported by the caudal septum by just forming a bridge between lower lateral cartilage and quadrangular septum using a wider SG that mimics septal extension grafts.
