Summary
Rhinoplasty surgeons face large nostril/small tip disproportion. A 55:45 nostril-to-tip ratio is ideal, requiring tip projection and nostril reduction for correction.
Area of Science:
- Plastic Surgery
- Facial Anatomy
Background:
- Large nostril and small tip disproportion presents a unique surgical challenge in rhinoplasty.
- Accurate analysis of intrinsic and extrinsic factors is crucial for addressing this deformity.
Observation:
- The nostril axis measurement subdivides the nose into nostril (55%) and tip (45%) components.
- A nostril-to-tip ratio of 60:40 is considered acceptable.
- The anatomical deformity involves divergent alar cartilages, a short infralobular segment, and a flat, ill-defined domal segment.
Findings:
- Surgical correction necessitates increasing intrinsic tip projection via infralobular segment lengthening.
- Nostril reduction is a key component of the surgical solution.
- The advocated technique combines a three-stitch tip procedure with nostril sill/alar wedge resections.
Implications:
- This approach offers a structured method for correcting large nostril/small tip disproportion.
- Understanding the anatomical components guides surgical planning and technique selection.
- Successful correction can significantly improve aesthetic outcomes in rhinoplasty.

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...

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...

01:29Administering Oxygen by Nasal Cannula
Oxygen therapy is critical to patient care, especially for those struggling with respiratory issues. This intervention increases the oxygen concentration in the lungs, enhancing the amount of oxygen transported to the body's tissues. One standard method of delivering supplemental oxygen is through a nasal cannula, a non-invasive device that provides low to medium oxygen concentrations.
