Summary
Olfactory groove and planum sphenoidale meningiomas are common, slow-growing skull base tumors. Surgical resection is the primary treatment for these low-grade neoplasms.
Area of Science:
- Neurosurgery
- Oncology
- Skull Base Surgery
Background:
- Olfactory groove and planum sphenoidale meningiomas represent common skull base tumors.
- These neoplasms are typically histologically low-grade but can attain significant size due to their insidious growth pattern.
Purpose of the Study:
- To review the characteristics and management of olfactory groove and planum sphenoidale meningiomas.
- To emphasize the role of surgical resection in treating these skull base tumors.
Main Methods:
- Literature review of olfactory groove and planum sphenoidale meningiomas.
- Analysis of surgical outcomes and treatment strategies.
Main Results:
- These meningiomas are often diagnosed at a large size due to asymptomatic or slowly progressive symptoms.
- Surgical resection is the definitive treatment, with varying approaches depending on tumor size and location.
Conclusions:
- Early diagnosis and surgical intervention are crucial for favorable outcomes in olfactory groove and planum sphenoidale meningiomas.
- Surgical resection remains the gold standard for managing these skull base tumors.

01:03Olfactory Receptors: Location and Structure
11.0K
The process of olfaction, also known as the sense of smell, is a sophisticated chemical response system. The specialized sensory neurons that facilitate this process, known as olfactory receptor neurons, are situated in an upper segment of the nasal cavity, known as the olfactory epithelium. Olfactory sensory neurons are bipolar, with their dendrites extending from the epithelium's apex into the mucus that lines the nasal cavity. Airborne molecules, when inhaled, traverse the olfactory...

01:19Cranial and Spinal Meninges
3.2K
The cranial and spinal meninges are complex protective structures surrounding the central nervous system (CNS), consisting of the brain and spinal cord. These meninges consist of the dura mater, the arachnoid mater, and the pia mater. They protect the CNS, provide structural support, and aid in circulating cerebrospinal fluid (CSF).
Cranial Meninges
These meningeal layers cover the cranium. The dura mater is the outermost layer of cranial meninges. It is a thick and durable membrane of dense...

47.8K
The sense of smell is achieved through the activities of the olfactory system. It starts when an airborne odorant enters the nasal cavity and reaches olfactory epithelium (OE). The OE is protected by a thin layer of mucus, which also serves the purpose of dissolving more complex compounds into simpler chemical odorants. The size of the OE and the density of sensory neurons varies among species; in humans, the OE is only about 9-10 cm2.

01:20Physiology of Smell and Olfactory Pathway
11.7K
Humans detect odors with the help of specialized cells located in the upper part of the nasal cavity, called olfactory receptor neurons (ORNs). ORNs possess hair-like structures called cilia, which are receptive to sensations from the inhaled air. When an odorant molecule binds to a specific receptor on the cell of the cilia, it leads to a series of events that ultimately cause the ORN to send electrical signals to the olfactory bulb in the brain through the olfactory nerves.

01:24Nose and Nasal Cavity
8.9K
The nose is composed of an observable exterior segment (external nose) and an internal segment within the skull known as the nasal cavity (internal nose). The external nose, visible on the face, consists of a framework of bone and hyaline cartilage enveloped in skin and muscle and lined with a mucous membrane. This structure is supported by the frontal bone, nasal bones, and maxillary bone and is supplemented by a cartilaginous framework comprising the septal nasal cartilage, lateral nasal...

01:27Cranial Bones: Lateral View
4.2K
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...
