Abstract:
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.

Cranial Bones: Lateral View
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...

Cranial Bones: Superior and Posterior View
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...
