The use of PDS foil in connection with cartilage facilitates surgical correction of severe septal deformities, additionally providing support for the nasal dorsum. The histological examination showed that no inflammatory or foreign body reaction occurred. Cartilage regeneration was even found. The foil was completely resorbed within 25 weeks, avoiding the long-term complications that occur with other artificial implants.

To determine whether late complications after septoplasty in growing septal cartilage in children can be prevented by the use of a resorbable polydioxanone (PDS) foil in combination with the cartilage. Design: Animal study with 45 young rabbits, operated on at the nasal septum. Four typical septoplasty procedures were carried out, including elevation of the mucoperichondrium, cartilage excision, and reimplantation of crushed and noncrushed cartilage; for each of the procedures, resorbable PDS foil was used in half of the animals. Observation time ranged from 2 weeks to 5 months, to observe the healing process until complete outgrowth of the septum and complete resorption of the foil were achieved.

Use of polydioxanone plate attached to nasal septal cartilage facilitates surgical correction of severe septal deformities and supports the nasal dorsum until healing.

We present our experience and results after using polydioxanone (PDS) foil in septal reconstruction. In a period of 2 years, 12 patients who were admitted in our department with severe septal deviation and breathing problems underwent septoplasty under general anaesthesia. The nasal septum was approached via an external approach. In all patients, after resecting and exposing the septum, the removable piece after being divided into straight pieces, was sutured onto an appropriate sized PDS foil and reimplanted together between the mucoperichondrium flaps. Sutures were placed to fixate the "new septum" to the nasal dorsum and to the anterior nasal spine. The immediate postoperative course was unremarkable and in a follow-up appointment 6 months and 1 year postoperatively, one complication occurred, with septum subluxation noted in one patient. Use of PDS foil in septal reconstruction is an important surgical option for the correction of the markedly deviated nasal septum. Fixation of the straightened and replanted septum at the nasal dorsal septum border with the upper lateral cartilages and at the nasal spine is essential.
