Summary
Caudal septal dislocation significantly impacts nasal symmetry, causing notable asymmetry in the nostril axis angle (NAA). This finding is crucial for surgeons performing septorhinoplasty on trauma patients.
Area of Science:
- Plastic Surgery
- Otolaryngology
- Facial Anatomy
Background:
- Nasal tip reconstruction is complex in post-traumatic cases.
- Nose aesthetics depend on tip definition, projection, and rotation.
- Caudal septal dislocation can lead to nasal asymmetry.
Purpose of the Study:
- To determine if caudal septal dislocation causes significant nostril axis angle (NAA) asymmetry.
- To assess the relationship between dislocation side and NAA magnitude.
- To inform surgical planning for septorhinoplasty.
Main Methods:
- Photographic assessment of NAA was conducted.
- A study group of 26 patients with caudal septal dislocation was compared to a control group of 26 patients without dislocation.
- All patients had sustained nasal trauma and were awaiting septorhinoplasty.
Main Results:
- Caudal septal dislocation resulted in a mean NAA difference of 7.95°, compared to 1.38° in the control group.
- A greater degree of upward tip rotation was observed on the side of dislocation.
- This rotation contributed to a larger NAA on the affected side.
Conclusions:
- Caudal septal dislocation is a significant cause of NAA asymmetry.
- The dislocation leads to increased nasal tip rotation on the affected side.
- Awareness of this anatomical distortion is vital before surgical intervention.

01:03Olfactory Receptors: Location and Structure
The process of olfaction, also known as the sense of smell, is a sophisticated chemical response system. The specialized sensory neurons that facilitate this process, known as olfactory receptor neurons, are situated in an upper segment of the nasal cavity, known as the olfactory epithelium. Olfactory sensory neurons are bipolar, with their dendrites extending from the epithelium's apex into the mucus that lines the nasal cavity. Airborne molecules, when inhaled, traverse the olfactory...
01:24Nose and Nasal Cavity
The nose is composed of an observable exterior segment (external nose) and an internal segment within the skull known as the nasal cavity (internal nose). The external nose, visible on the face, consists of a framework of bone and hyaline cartilage enveloped in skin and muscle and lined with a mucous membrane. This structure is supported by the frontal bone, nasal bones, and maxillary bone and is supplemented by a cartilaginous framework comprising the septal nasal cartilage, lateral nasal...
01:30Epistaxis
Epistaxis, or nosebleeds, occurs when small, swollen blood vessels in the nasal mucous membrane rupture. Typically, the anterior septum is the primary site of occurrence.
Etiology
Possible causes of this condition include high blood pressure, trauma, low humidity, upper respiratory tract infections, allergies, foreign bodies, nasal inhalation of corticosteroids or illicit drugs, excessive use of decongestant nasal sprays, facial or nasal surgery, anatomic malformation, tumors, or systemic...

01:15Unsymmetric Bending - Angle of Neutral Axis
Unsymmetrical bending occurs when a structural member is subjected to bending moments in a plane that does not align with the member's principal axes. This scenario typically arises in beams and other structural components when loads are applied at non-ideal angles, introducing complexities in stress analysis.
When a bending moment is applied at an angle θ concerning the vertical axis of a symmetrical member, it can be resolved into components along the member's principal centroidal axes. The...

01:27Cranial Bones: Lateral View
The lateral view of the cranium is dominated by temporal, sphenoid, and ethmoid bones.
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...
