Impact of facial bone deformity on nasal shape

Abstract

The aim of this study was to analyze nose shape and size in subjects with sagittal facial deformities.Methods: One hundred fifteen subjects were included for orthognathic surgery; the previous cone bean computed tomography was used to perform the analysis. The sample consisted of 46 males (40%) and 69 females (60%); the nasal morphology in frontal view and profile, the deviation of the nasal septum, the skeletal class and the sagittal position of the maxilla were compared using the Spearman test, considering a P value < 0.05.Results: Males had a greater vertical nasal skeletal measurement (P = 0.0006), greater cartilaginous nasal height ( P = 0.0001) and greater horizontal distance between the A point and Prn (P = 0.001). Considering the sagittal position of the maxilla, subjects with maxillary prognathism had a higher nasal morphology value than subjects with a retrognathic maxilla. In addition, nasal septum deviation was statistically related to facial class II (P = 0.03) with significantly more deviation than class III subjects. Conclusion:It may be concluded that there are variables in facial deformities related to nose shape and have to be included in the surgical plan for orthognathic surgery or rhinoplasty.

“…According to our observations, in cases of rhinoplasty simultaneously to Le Fort I osteotomy, the surgeon has to consider the anatomy of the FD and proportions with the nose (Ravelo et al, 2021); in terms of the surgical technique, the nasal septum detached using the Le Fort I has to be fixed to the ANE, using 3-0 nylon suture in the anterior base of the nose; the nasal base position and the tip morphology has to be studied before and after maxillary osteotomy because the nose will be different after Le Fort I mobilization.…”

“…Anthropometric studies [1] form a research area devoted to observations of the appearance of the human skull. Facial measures, proportions, and symmetry [2]- [4] are very important in dentistry, orthodontics, plastic surgery, recognition of different diseases and their therapy, anthropological skull analysis [5], [6], and forensic identification [7]. An investigation of the mechanical properties of human skull bone and its geometry [8] form an associated research area.…”
