Sutures of the Skull

Sutures of the Skull

The human skull is composed of several bones that come together to protect the brain and support the structures of the face. The junctions where these bones meet are called sutures.
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...

Overview of the Skull

Overview of the Skull

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...

Exponential Functions with Base e

Exponential Functions with Base e

Exponential functions with base e are essential for modeling continuous processes of growth and decay. The constant e, approximately 2.718, naturally arises in systems where change occurs proportionally to the current value. A positive exponent represents continuous growth, while a negative exponent represents continuous decay. These functions are especially useful for describing situations where change happens smoothly over time rather than in discrete steps.One clear example of exponential...

Nose and Nasal Cavity

Nose 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...

Dimensional Analysis

Dimensional Analysis

Dimensional analysis, also known as the factor label method, is a versatile approach for mathematical operations. The main principle behind this approach is: the units of quantities must be subjected to the same mathematical operations as their associated numbers. This method can be applied to computations ranging from simple unit conversions to more complex and multi-step calculations involving several different quantities and their units.
Conversion Factors and Dimensional Analysis
The unit...

Administering Oxygen by Nasal Cannula

Administering 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.
Nasal Cannulas
A nasal cannula is a lightweight tube split into two prongs placed in the nostrils,...

Summary

Three-dimensional endoscopic transnasal surgery for skull base diseases does not significantly alter nasal airflow or olfactory function. Postoperative nasal complaints were not increased, preserving patients' quality of life.

Area of Science:

Neurosurgery
Otolaryngology
Skull Base Surgery

Background:

Endoscopic transnasal transsphenoidal surgery is a standard approach for sellar, parasellar, and clival diseases.
Objective evaluation of nasal function post-surgery is crucial for patient outcomes.

Purpose of the Study:

To objectively assess nasal airflow resistance and olfactory function after 3D endoscopic transnasal transsphenoidal surgery.
To evaluate the impact of this surgical technique on nasal complaints and quality of life.

Main Methods:

100 patients undergoing 3D endoscopic transnasal surgery were enrolled.
Nasal airflow (rhinomanometry) and olfactory function (Sniffin' Sticks) were measured preoperatively and at 3 and 6 months postoperatively.

Main Results:

No significant changes in nasal airflow resistance or olfactory function were observed.
Temporary declines in nasal respiratory and olfactory function were noted with crusting and synechiae, respectively, which resolved over time.
No correlation was found between nasal function and reconstruction with flaps.

Conclusions:

3D endoscopic transnasal transsphenoidal surgery is a safe and effective technique for skull base pathologies.
The procedure does not lead to persistent nasal respiratory or olfactory deficits.
Patient quality of life is maintained without increased nasal complaints post-surgery.
