Abstract
In cases of weak or deficient caudal septum, the caudal septum extension graft (CSEG) is the most commonly used reconstructive method. In the current study we introduce a newly-designed conchal cartilage CSEG and evaluate its cosmetic and functional outcomes. The graft has an average length of 3 ± 0.3 cm and composed of a distal double-layered part, which is 3 to 4 mm wide and a proximal single-layered part, which is 1.2 to 1.7 cm wide. The graft design allows the proximal single-layered part to be fixed on either sides of the caudal septum while keeping the distal double-layered segment in the midline. The study included 230 patients, of which 83% were revisions, all patients completed a validated patient-reported outcome measure (PROM) questionnaire pre- and postoperatively. The PROMs used were either the Nasal Obstruction Symptom Evaluation (NOSE) survey or the Standardized Cosmesis and Health Nasal Outcomes Survey (SCHNOS). During the mean follow-up period of 18.2 months (range: 9–192 months) no serious complications were encountered and only six cases (2.3%) required minor revisions of the CSEG.
Using the proposed conchal cartilage, CSEG resulted in an improved cosmetic and functional outcome as evidenced by the significant postoperative improvement in the NOSE, SCHNOS-O, and SCHNOS-C scores with a p-value <0.001, <0.05, and <0.0001, respectively. The graft provided adequate tensile strength and support to the nasal tip, which resulted in improved tip projection, rotation, definition, and symmetry, while maintaining a degree of flexibility and elasticity which is much more than that of the rib or even the septum thus resulting in the most natural feel of the nasal tip lobule.
