Background:
For East Asians, rhinoplasty procedures are predominantly focused on reconstructing a well-defined nasal tip. In this study, the authors present a new graft design for the columellar strut that is similar to the shape of a comma mark. As one integrated piece, the graft undertakes the roles of providing solid support for the tip, modifying different angles, as well as relationships between the tip and columella.
Methods:
One hundred and sixty-five female patients, ranging in age from 18 to 42 years (average 27.1 years), received augmentation rhinoplasty surgery over the past 4 years with an average postoperative follow-up of 12 months. Among these patients, 78 of them were primary cases and others were secondary or more. The cartilaginous framework was reconstructed based on comma strut with other grafts including spreaders and dorsal onlay grafts.
Results:
Patients' own evaluations on the overall improvements of the nose rendered high satisfaction rate. During the long-term follow-up, 8 cases presented asymmetrical nostrils with slightly deviated columella; minor revision surgeries were performed. Another 3 cases presented dorsal graft warping and were also corrected. No other major complications were encountered.
Conclusions:
The comma strut provides a reliable support for the nasal tip; its dual curved structure plays the instrumental role in defining the lobular-columellar angle as well as modifying the supratip break. This graft design offers good control of tip and columella; as a result, consistent, reproducible results can be achieved.
