Insights

Pediatric pleomorphic adenoma, the most common benign salivary gland tumor, requires careful management. This study found a low recurrence rate (4.9%) after surgical excision, emphasizing the need for continued patient monitoring.

Area of Science:

  • Pediatric Otolaryngology
  • Head and Neck Surgery
  • Surgical Oncology

Background:

  • Pleomorphic adenoma is the most frequent benign tumor of salivary glands in children.
  • Concerns regarding recurrence and malignant transformation necessitate effective treatment strategies.

Purpose of the Study:

  • To review the clinical presentation, diagnostic evaluation, and management of pleomorphic adenoma in pediatric patients.
  • To analyze treatment outcomes, including complications and recurrence rates.

Main Methods:

  • Retrospective chart review of 41 patients under 20 years old treated for pleomorphic adenoma from 1998 to 2017.
  • Data collected included demographics, clinical findings, imaging results (ultrasound, CT, MRI), surgical treatment, complications, and follow-up duration.
  • Analysis focused on identifying patterns of occurrence, treatment efficacy, and recurrence.

Main Results:

  • Pleomorphic adenomas were predominantly found in major salivary glands (78.0%), particularly the parotid gland.
  • Minor salivary gland involvement occurred in the palate, buccal mucosa, parapharyngeal space, and upper lip.
  • Surgical excision was universally performed, with a low recurrence rate of 4.9% and manageable postoperative complications such as transient facial paresis.

Conclusions:

  • Preoperative imaging is crucial for evaluating pediatric pleomorphic adenoma.
  • Complete surgical excision with clear margins is the primary treatment goal.
  • Despite a low recurrence rate, long-term follow-up is recommended for pediatric patients.

Arteries of the Head and Neck

The human body's intricate network of arteries ensures that every organ system receives the necessary oxygen and nutrients for optimal function. The arterial network in the head and neck region is particularly complex, providing vital blood flow to the brain, eyes, and other critical structures. Prominent arteries in this region include the internal carotid arteries and the vertebral arteries.
The internal carotid arteries supply blood to the anterior portion of the cerebrum. They enter the...

Veins of Head and Neck01:19

Veins of Head and Neck

The blood drainage from the head and neck is primarily managed by three pairs of veins: the external jugular, internal jugular, and vertebral veins. The external jugular veins drain superficial scalp and face structures, passing over the sternocleidomastoid muscles to empty into the subclavian veins.
On the other hand, the vertebral veins, unlike their arterial counterparts, are not primarily responsible for brain drainage. Instead, they drain the cervical vertebrae, spinal cord, and some small...

Self-Presentation: Self-Monitoring and Self-Handicapping

People can go to great lengths to protect their self-image and present themselves in ways that they want others to see them. Sociologist Erving Goffman presented the idea that a person is like an actor on a stage. Calling his theory dramaturgy, Goffman believed that we use “impression management” to present ourselves to others as we hope to be perceived. Each situation is a new scene, and individuals perform different roles depending on who is present (Goffman, 1959). Think about...

Self-Presentation

Self-presentation is a fundamental aspect of social interaction, shaping both how others perceive individuals and how they view themselves. This dynamic process influences behaviors in various social settings, often leading people to adjust their appearance, speech, and demeanor to align with their desired identity. While self-presentation can be deliberate or unconscious, it plays a critical role in interpersonal relationships and self-perception.Forms of Self-PresentationSelf-presentation can...

Strategies of Self-Presentation I: Strategic Self-Presentation

Strategic self-presentation refers to individuals' intentional efforts to influence how others perceive them. This process is employed in various social and professional settings, such as job interviews, dating, politics, and legal contexts, where individuals seek to shape impressions to gain social or material advantages. While people generally present themselves in ways that align with their authentic characteristics, external factors, such as cognitive load, can hinder their ability to...

Processes of Self-Presentation

Effective self-presentation is a central component of social interaction and identity construction. It relies on the dynamic processes of defining the situation and engaging in self-disclosure. These mechanisms help individuals navigate social context expectations and manage how others perceive them, fostering mutual understanding and relationship development.Defining the SituationSocial situations are shaped by collectively understood frames—a set of widely understood rules or...
