ABSTRACT
Nasal surgery in children with rhinoseptal or septal deformity has been a thoroughly discussed subject. Some surgeons prefer to take expectant conducts, because of fear of negative post-surgical results related to an alteration of nasal and facial growth. At the National Institute of Pediatrics (NIP) it had been observed that the correction of these alterations seemed to improve nasal, aesthetic and/or functional conditions of the boy, and allowed a better craniofacial development; however, this fact had not been studied systematically. In this study, we evaluated the craniofacial growth in Mexican children with rhinoseptal deformity or septal deviation, managed by means of rhinoseptoplasty or septoplasty with Cottle´s technique. The study is observational, comparative, prospective, and longitudinal, in which we included children younger than 18 years subjected to septoplasty or rhinoseptoplasty in the Department of Otorhinolaryngology from June 1997 to October 2000. We performed a lateral simple x-ray of the skull on each patient, in which cephalometric measurements with Steiner´s technique took place; two years after surgery the same radiological study was carried out again. The angles produced between the esphenoidal (S), nasion (N), and maxillary (A) points (SNA, according to Steiner) were compared to the angles produced between the esphenoidal (S), nasion (N), and mandibular (B) (SNB, according to Steiner) points. Comparing pre- and postsurgical SNA and SNB angles, we used Student´s t for related samples or Mann Whitney´s Utest, considering significant a value of p ‹ 0.05. Of the 86 patients, we applied exclusion criteria to 21 and elimination criteria to 26, finally including a total of 39 patients, of which 12 are under pre- and post-surgical control until this moment, and the remaining 27 are in follow-up. Of the 12 patients included, eight present septal deviation and four rhinoseptal deformity (Table 1). The median of the SNA angle in the 12 patients before surgery was 81°, and after surgery it was 80.6° (normal value of the SNA angle = 82° ± 2). The median of the SNB angle before surgery was 77.4°, and after surgery 77.9° (normal value of the SNB angle = 80° ± 2). In this work we conclude that there are not significant differences between the SNA angle and pre- and postsurgical SNA, nor between SNB and pre- and postsurgical SNB, although they do exist individually.REFERENCES
