Extended L-shaped Spreader Graft for Correction of Combined Dorsal and Caudal Nasal Septal Deviations.

Abstract

Summary:Although a wide range of surgical techniques have been proposed to straighten the deviated cartilaginous nasal dorsum and maximize nasal function, recurrence is common because of cartilage memory and scar contractures. An extended L-shaped spreader graft, a permanent support, was developed to correct functional and aesthetic problems, to prevent recurrence, and to maintain the correction of the septum stable and strong. This technique was utilized in 16 cases of deviated cartilaginous dorsum. All patients were subjected to a detailed history, physical examination, CT scan of the nose, and photographic documentation preoperatively. The patients were followed up during a period of 3 months to 4 years. According to physical examination, postoperative photography, and patients’ satisfaction, the final results were categorized as excellent, good, or poor. The results were as follows: 14 patients (87.5%) were classified as excellent, as their noses were completely straight, and this was consistent with physical examination and postoperative photographs. Two patients (12.5%) were classified as good because there was a minimal residual deviation according to either photographs or clinical examinations. This minimal deformity was not experienced by the patients. In conclusion, consistent, reproducible results were achieved with using the autologous extended L-shaped spreader graft for controlling and maintenance of the dorsal and caudal septal deviation after correction. It is one piece of L-shaped graft of autogenous cartilage fixed to the original septal L-strut. It is regarded as an anatomical graft that provides sustained cephalocaudal support, preserves pliability of the lobule, and maintains stability as an independent stabilizer for the native strut.
