The Parathyroid Glands00:59

The Parathyroid Glands

5.6K
The two pairs of parathyroid glands embedded within the posterior surface of the thyroid gland are restricted by a dense capsule around them. These glands comprise two distinct cell populations—parathyroid oxyphil and parathyroid principal cells- pivotal in calcium homeostasis.
Oxyphil cells, whose functions remain elusive, emerge during late puberty, adding a layer of complexity to the parathyroid gland's intricacies. In contrast, principal parathyroid cells undertake a vital role by...

Cranial Bones: Lateral View

7.7K
The lateral view of the cranium is dominated by temporal, sphenoid, and ethmoid bones.
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...

Cranial Part of Parasympathetic Division

2.4K
The cranial part of the parasympathetic division plays a crucial role in regulating the visceral functions of the head and specific structures in the neck, thoracic, and abdominopelvic cavities. Preganglionic fibers of the parasympathetic division exit the brain through cranial nerves III (oculomotor), VII (facial), IX (glossopharyngeal), and X (vagus), delivering parasympathetic output to the respective visceral structures.
The vagus nerve (cranial nerve X) alone accounts for approximately 75...

Area of Science:

  • Otolaryngology
  • Neurosurgery
  • Oncology

Background:

  • Temporal bone paragangliomas (TBPs) are benign tumors originating from neural crest cells.
  • Common management includes surgical excision, radiotherapy, and observation.

Purpose of the Study:

  • To present clinical experience with TBPs.
  • To review existing literature data on TBP management.

Main Methods:

  • Retrospective review of 34 patients operated for tympanomastoid paraganglioma (TMP) or tympanojugular paraganglioma (TJP) over 15 years.
  • Analysis of patient charts for demographics, symptoms, surgical outcomes, and follow-up.

Main Results:

  • 34 patients (18 TMP, 16 TJP) were analyzed, with a mean age of 50.3 years.
  • Tinnitus and hearing loss were the most common symptoms.
  • Gross total resection rates were 94.4% for TMP and 62.5% for TJP.
  • Postoperative facial palsy occurred in 31.2% of TJP cases.

Conclusions:

  • Total surgical excision, potentially with preoperative embolization, is the main treatment for TBPs.
  • Radiotherapy, observation, and subtotal resection are viable options for specific patient groups, considering cranial nerve function, tumor size, and age.
