To study the nasal framework of patients in relation to CT scan and observe the Nasofrontal angle and Nasofacial angle in patients. This study is a prospective observational study. It was done from January 2020 to December 2020. It involved selection of patients with nasal complaints and external nasal deformity followed by their CT scan evaluation. It included a 3D analysis of the CT scan using a computer software. Preoperative photographic evaluation of the patient was done in frontal, lateral and basal view for a better understanding and correlation. Thirty patients were evaluated and their 3D reconstructed CT scans were observed. The mean Nasofrontal angle was 116.69°. The mean was 110.43° in males and 126.08° in females. The mean Nasofacial Angle was 37.68. The mean was 43.05° in males and 29.62° in females. There was a significant statistical difference seen. The demand for rhinoplasty in India is on rise. The studies done in the past have evaluated patients using plain 2D CT films. In this study, 3D reconstruction of CT scan has been done. There are meagre studies which describe the aesthetics of Indian population. It aids in preoperative evaluation and plan of surgery, enables a good doctor-patient communication. Also, it can be used for clinical learning of resident doctors.
