Summary
Advancing age is linked to shorter nasal bone overlap, increasing risks during septoplasty surgery. Surgeons should consider this when operating on elderly patients to prevent complications like saddle nose.
Area of Science:
- Otolaryngology
- Medical Imaging
- Geriatric Surgery
Background:
- Septoplasty is the primary surgical treatment for nasal septum deviation.
- Saddle nose deformity is a rare but serious complication of septoplasty.
- Damage to the keystone area, where nasal bone overlaps upper lateral cartilages, can cause saddle nose.
Purpose of the Study:
- To investigate factors associated with short nasal bone overlap.
- To identify risks for elderly patients undergoing septoplasty.
- To inform surgical precautions for septoplasty.
Main Methods:
- Computed tomography (CT) scans of 177 patients were analyzed.
- Data on age, sex, and disease were collected.
- Septal deviation and midline nasal bone overlap distance were measured using CT.
Main Results:
- Advanced age was significantly correlated with shorter midline nasal bone overlap.
- No significant association was found between septal deviation degree and bone overlap.
- Nasal sinus disease and sex did not significantly affect overlap distance.
Conclusions:
- Elderly patients exhibit shorter nasal bone overlap, necessitating careful surgical technique during septoplasty.
- Awareness of age-related anatomical changes is crucial for preventing saddle nose deformity.
- Adequate precautions are vital when performing septoplasty in the geriatric population.

01:27Cranial Bones: Lateral View
8.0K
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
16.2K
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...

01:18Classification of Bones
14.4K
The bones of the human skeletal system are of varied shapes, sizes, and functions. They can be classified based on their shape and function into four major classes: long bones, short bones, flat bones, and irregular bones. Some classifications include a fifth type, the sesamoid bones, as a separate class, whereas others categorize them under short bones.

01:08Overview of the Skull
9.1K
The cranium (skull) is the skeletal structure of the head that supports the face and protects the brain. It is subdivided into the facial bones and the brain case, or cranial vault. The facial bones underlie the facial structures, form the nasal cavity, enclose the eyeballs, and support the teeth of the upper and lower jaws.
The cranial vault surrounds and protects the brain and houses the middle and inner ear structures. This cavity is bounded superiorly by the rounded top of the skull, which...

01:14Cranial Bones: Superior and Posterior View
8.7K
The superior view of the cranium shows the frontal and paired parietal bones.
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,...

01:27Compact Bone
21.8K
Most bones contain compact and spongy osseous tissue, but their distribution and concentration vary based on the bone's overall function.
Compact bone, also called cortical bone, is the denser, stronger of the two types of bone tissue. It is found under the periosteum and in the diaphyses of long bones, where it provides support and protection. The microscopic structural unit of compact bone is called an osteon, or haversian system. Each osteon is composed of concentric rings of calcified...
