Objective: Basing on the key role the septum plays in midfacial growth, this study explored the effects of the techniques that can be applied to the septum in pediatric septorhinoplasty and of poly-p-dioxanone (PDS) plate usage on maxillofacial development. Methods: Thirty-three rabbits aged eight weeks were divided into five groups. The first group was taken as the control group and their growth was monitored without any intervention. In the remaining four groups septorhinoplasty was performed with different techniques. Volumes of the maxilla, the incisive bone, the mandible and maxillary sinus, length and width of the nasal bone were examined in 3D by tomography scanning at the beginning and at the end of the study and compared between the groups. Results: The nasal bone was observed to be shorter in the group that had osteotomy and mucosal elevation (p<0.05). While cartilage resection and use of crushed cartilage did not affect midfacial growth, incisive bone volume was significantly reduced and malocclusion developed in the group which PDS plate and composite crushed cartilage was used. Limited cartilage resection by preserving the dorsal stratum and crushed cartilage use had no significant effects on maxillofacial development parameters (p>0.05). Conclusion: Septal surgeries can be safely performed in the pediatric period with limited resections by observing the septodorsal cartilage. In our study, contrary to the reports in the literature, osteotomy and mucosa elevation were seen to adversely affect nasal bone growth (p<0.05). In the pediatric period, however, osteotomy is usually applied in patients presenting with extensive deviation after a nasal trauma, and if not treated, can lead to more serious deformities like short nasal bone, flattened nasal base, short columella, type ptosis. Therefore, osteotomy can be performed in order to prevent more serious deformities in pediatric period. Although positive results have been reported for PDS plate use in adults, in our study, it was observed to have negative effects on maxillofacial growth when used in developing noses. Invasive bone development significantly regressed and malocclusion developed. Compared to the other techniques used in our study, that the most statistically significant effect on maxillofacial development was seen in the PDS Plate Group suggests that the histological effects of PDS plate on developing noses should be further investigated. Moreover, whereas growth continues for 20-24 weeks in rabbits, maxillofacial development is a much longer process in humans. Therefore, clinical studies investigating the effects of PDS plate on developing noses are needed. [ABSTRACT FROM AUTHOR] |
