Summary
Cochlear implantation electrode misplacement is rare but serious. This study found that extra-cochlear insertion in three patients was successfully treated with revision surgery, avoiding complications.
Area of Science:
- Otolaryngology
- Neurosurgery
- Medical Device Technology
Background:
- Cochlear implantation is a vital auditory rehabilitation technique for pediatric and adult patients.
- While generally safe, intraoperative complications, including electrode misplacement, can occur.
Observation:
- A retrospective analysis of 423 cochlear implantations identified three cases of extra-cochlear electrode insertion.
- Misplacement occurred in the internal acoustic canal, superior semicircular canal, and internal carotid artery canal.
Findings:
- All three patients with extra-cochlear electrode insertion underwent successful re-implantation.
- No complications were observed following the revision surgeries.
Implications:
- This case series demonstrates that rare electrode misplacements during cochlear implantation can be effectively managed.
- A multidisciplinary approach is crucial for successful treatment and avoidance of adverse outcomes.

01:12Porin Insertion in the Outer Mitochondrial Membrane
4.7K
Porins are beta-barrel proteins translocated to the mitochondrial outer membrane through the TOM complex into the intermembrane space. Porin precursors bind TIM chaperones within the intermembrane space and are guided to the Sorting and Assembly Machinery complex or SAM complex on the outer mitochondrial membrane.
Three models describe the assembly of porins by the SAM complex and their insertion into the outer membrane. Model 1 suggests that porins are assembled outside the SAM channel as the...

100.7K
Around 4 billion years ago, oceans began to condense on earth while volcanic eruptions released nitrogen, carbon dioxide, methane, ammonia, and hydrogen into the primordial atmosphere. However, organisms with the characteristics of life were not initially present on earth. Scientists have used experimentation to determine how organisms evolved that could grow, reproduce, and maintain an internal environment.

01:18Classical Conditioning
2.1K
Associative learning, a core principle in behavioral psychology, involves forming connections between events and facilitating learned responses. This concept is vividly illustrated by classical conditioning, a process extensively studied by the Russian physiologist Ivan Pavlov. Pavlov's pioneering research on dogs' digestive systems led to the discovery that behaviors can be learned through association, laying the groundwork for classical conditioning.

01:28Conditions of Equilibrium
2.1K
Equilibrium refers to a state where a rigid body is not subjected to any translational or rotational motion. This state is achieved when the force and couple acting on a rigid body equal zero. When the system of external forces results in a net effect equivalent to zero, the rigid body is considered to be in equilibrium.
Internal forces are not considered for conditions of equilibrium because they occur in equal and opposite pairs within the body, effectively canceling each other. As a result,...

Operant conditioning, a key concept in behavioral psychology, involves using reinforcement and punishment to alter the likelihood of a behavior being repeated. B.F. introduced this type of conditioning. Skinner focused on voluntary behaviors and the consequences that follow them, influencing whether these behaviors will be strengthened or diminished.
Reinforcement in operant conditioning can be positive or negative, both of which serve to increase the likelihood of a behavior. Positive...

Integral membrane proteins are proteins adhered to the lipid bilayer of a cell organelle or membrane. They can be of two types: transmembrane integral proteins that span the lipid bilayer and monotopic proteins that are attached to either side of the membrane but do not pass through it.
Integral transmembrane proteins possess transmembrane and extra membrane domains. The transmembrane domains are primarily made of 20-25 hydrophobic amino acids arranged in a helical secondary confirmation. These...
