Summary
Pneumocephalus with skull base defects requires prompt diagnosis. Endoscopic endonasal surgery offers a high success rate for reconstruction, with conservative treatment for early-stage cases.
Area of Science:
- Neurosurgery
- Otolaryngology
- Radiology
Background:
- Complex skull base defects can lead to pneumocephalus, a condition involving air within the cranial cavity.
- Pneumocephalus presents with diverse symptoms, including neurological deficits, cerebrospinal fluid leaks, and altered consciousness.
Purpose of the Study:
- To analyze treatment experience for complex skull base defects with pneumocephalus.
- To develop an optimal treatment strategy for this condition.
Main Methods:
- Retrospective review of 30 patients treated between 2001 and 2017.
- Analysis of demographic, clinical, and treatment data.
- Comparison of outcomes with literature findings.
Main Results:
- The study included 30 patients (59% male, mean age 41) with traumatic (59%), iatrogenic (36%), or spontaneous (5%) causes.
- Common presentations included neurological symptoms (41%), CSF leak (36%), and impaired consciousness (27%).
- Endoscopic endonasal reconstruction achieved a 91% success rate, with 9% recurrence and 18% meningitis complications.
Conclusions:
- Early diagnosis of pneumocephalus is crucial for selecting appropriate treatment.
- Conservative management is indicated for early-stage cases, while surgical intervention is necessary for tension pneumocephalus and significant defects.
- Endoscopic endonasal techniques are the preferred surgical approach for skull base defect reconstruction.

01:22Sutures of the Skull
10.2K
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...

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...

Lumber defects, which can affect both the appearance and structural integrity of wood, include a variety of growth and manufacturing flaws. Growth defects such as knots and knotholes occur where branches were once attached to the tree trunk, with knotholes forming when these knots fall out. Other natural defects include decay and insect damage, which compromise the wood's strength and durability.

A type of Lewis acid-base chemistry involves the formation of a complex ion (or a coordination complex) comprising a central atom, typically a transition metal cation, surrounded by ions or molecules called ligands. These ligands can be neutral molecules like H2O or NH3, or ions such as CN− or OH−. Often, the ligands act as Lewis bases, donating a pair of electrons to the central atom. These types of Lewis acid-base reactions are examples of a broad subdiscipline called coordination...

02:41Protein Complex Assembly
16.7K
Proteins can form homomeric complexes with another unit of the same protein or heteromeric complexes with different types. Most protein complexes self-assemble spontaneously via ordered pathways, while some proteins need assembly factors that guide their proper assembly. Despite the crowded intracellular environment, proteins usually interact with their correct partners and form functional complexes.

2.9K
Groups of proteins may form a complex where each protein in this complex has a different role in the overall execution of the complex’s function. Often some of the proteins in the complex can be replaced by a closely related variant to give a complex that contains many of the same components yet is functionally distinct.
