Resumen
Las anomalías de la primera hendidura branquial (FBCAs) tipo II pueden ser multicéntricas, y más del 27 % de los casos muestran patología más allá del quiste primario. Esto apoya la resección quirúrgica extensa para las FBCAs tipo II para prevenir la recurrencia.
Área de la Ciencia:
- Otorrinolaringología; Cirugía Pediátrica; Biología del Desarrollo
- Area_of_Science
Sus antecedentes:
- Las anomalías de la primera hendidura branquial (FBCAs) surgen de errores en el desarrollo del canal auditivo externo.; Una nueva clasificación del Grupo Internacional de Otorrinolaringología Pediátrica (IPOG) clasifica las FBCAs por ubicación: Tipo I (externo) y Tipo II (que involucra la glándula parótida).; El consenso de la IPOG recomienda la resección extensa de las FBCAs para minimizar la recurrencia.
- Background
Objetivo del estudio:
- Investigar la posible naturaleza multicéntrica de las FBCAs tipo II.; Buscar evidencia histológica que respalde la recomendación de la IPOG para la resección quirúrgica extendida de las FBCAs tipo II.
- Purpose_of_the_Study
Principales métodos:
- Análisis histopatológico de resecciones archivadas de FBCAs tipo II.; Evaluación de lesiones satélite o tractos filamentosos indicativos de enfermedad multifocal o extensión más allá de la lesión principal.
- Main_Methods
Principales resultados:
- Se analizaron veintidós especímenes de tejido de FBCA en la glándula parótida.; Más del 27 % (6/22) de los especímenes exhibieron tejido de FBCA externo a la lesión principal o múltiples restos epiteliales distintos, lo que sugiere multicentricidad.
- Main_Results
Conclusiones:
- Las FBCAs tipo II demuestran características extensas y potencialmente multicéntricas.; Estos hallazgos validan el consenso de la IPOG para una disección quirúrgica más completa y la extirpación del tejido circundante para mejorar la prevención de recurrencias.
- Conclusions

01:22Cranial Nerves: Types Part II
4.5K
Cranial nerves are responsible for transmitting motor and sensory information between the brain and various parts of the body. There are twelve pairs of cranial nerves. While the first six innervate the head and neck, the latter six nerves innervate the head and neck, as well as organs and tissues in the thoracic and abdominal cavities. They facilitate communication, expression, and autonomic control within the human body.

Cranial nerves are responsible for transmitting motor and sensory information between the brain and various parts of the body. There are twelve pairs of cranial nerves, with the first six being essential in sensory perception, motor control, and autonomic functions related to the head and neck.
Olfactory Nerve (Cranial Nerve I)
The olfactory nerve, or cranial nerve I, is unique as it is purely sensory and dedicated to the sense of smell. This nerve originates in the olfactory epithelium of the...

01:22Microtubules in Signaling
2.1K
The primary cilium, made up of microtubules, acts as antennae on the cell surfaces for relaying external stimuli into the cells. These fine hair-like structures are present, generally one per cell. These are non-motile cilia in a 9+0 microtubules arrangement, where the central pair of microtubules are absent. The primary cilia arise from the basal body embedded in the cell membrane. Intraflagellar transport (IFT) carries requisite proteins from the cytoplasm to the cilium because the primary...

01:30Neurulation
45.2K
Neurulation is the embryological process which forms the precursors of the central nervous system and occurs after gastrulation has established the three primary cell layers of the embryo: ectoderm, mesoderm, and endoderm. In humans, the majority of this system is formed via primary neurulation, in which the central portion of the ectoderm—originally appearing as a flat sheet of cells—folds upwards and inwards, sealing off to form a hollow neural tube. As development proceeds, the...

01:19Cranial Nerves: Overview and Anatomy
4.3K
The cranial nerves are an important part of the complex network of nerves in the human body. These nerves emerge directly from the brain and are responsible for transmitting essential information between the brain and various parts of the head and neck. There are 12 pairs of cranial nerves, systematically numbered using Roman numerals from I to XII, beginning from the anterior and moving to the posterior of the brain. Each cranial nerve is uniquely identified by names that reflect its function...

01:19Cadherins in Tissue Organization
3.9K
The cadherins are a superfamily of cell adhesion molecules comprising over 180 variants, with specific tissues expressing a particular combination of cadherin types. Cadherins generally exhibit homophilic binding; i.e., cadherins on one cell bind to cadherins of the same or closely related type on another cell. Thus, cells of the same type have a specific affinity to bind to each other and sort themselves into clusters to form tissues.
