The Influence of PDS in Patients under Septoplastic Surgery

It is a well-known fact that deviation of bony or cartilaginous septum can induce airway obstruction. Therefore, fixing the deviated part in a refined and straight line is one of the substantial challenges in otolaryngology. There are huge varieties of methods to eliminate this deviation.

In this study, we desire to assess the efficiency of polydioxanone plate (PDS), fixed to the cartilage of nasal septum, to determine the mechanical safety over septoplasty, as the components of cartilage had been healed.

In the following study, 48 patients with septal deviation, referring to an academic hospital in Iran for one year, were investigated. They underwent external and endoscopic septoplasty combined with the polydioxanone plate. The data was gathered in a questionnaire including the deviation of nasal septum, infection, septal hematoma, saddle nose, columella retraction and polly beak deformity.

Due to the septal injury resulted from trauma, a total of 27.1% patients was transferred to our hospital. Our results showed the cause and type of septal deviation had no effect on surgical results (p = 0.3), and acute complications were observed in only two patients (4.2%). After 3-6 months of follow up, 5 patients (10.42%) had long-term complications, while satisfactory results were obtained in 39 subjects (83%).

Absorbable plate, polydioxanone, connected to cartilage was found safe and effective. It could facilitate the modification rates of surgical processes in septal deviation and had the ability to support the nasal dorsum till it gradually get recovered, without the long-term complications occurring in other techniques.
