Nose and Nasal Cavity01:24

Nose and Nasal Cavity

12.8K
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...

Anatomy of Respiratory System I: Upper Respiratory Tract

5.7K
The upper respiratory tract plays a vital role in the respiratory system, comprising several structures that facilitate air intake and prepare air for the lungs. It also serves as the first line of defense against pathogens and particles. This tract includes the nose and nasal cavity, the oral cavity, the paranasal sinuses, and the pharynx, each with specific functions and features.
Nose and nasal cavity
The nose and nasal cavity represent the main external openings of the respiratory tract....

Cranial Bones: Lateral View01:27

Cranial Bones: Lateral View

7.5K
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...

Suctioning the Nasopharyngeal Airway01:29

Suctioning the Nasopharyngeal Airway

3.9K
Nasopharyngeal suctioning is a procedure to remove secretions from the upper part of the respiratory tract that the patient cannot clear independently. It helps maintain airway patency and prevents complications such as aspiration pneumonia.

Olfactory Receptors: Location and Structure01:03

Olfactory Receptors: Location and Structure

12.0K
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...

Cranial Nerves: Types Part I01:14

Cranial Nerves: Types Part I

5.5K
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, 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...

    Area of Science:

    • Otolaryngology
    • Endoscopic Sinus Surgery
    • Anatomy

    Background:

    • Safe and complete paranasal sinus surgery requires understanding fixed anatomical landmarks.
    • Variable anatomy can complicate surgical dissection and outcomes.

    Purpose of the Study:

    • To define the paranasal surgical box and its vertical component for endoscopic sinus surgery.
    • To elucidate key anatomical landmarks and limits of dissection within the paranasal sinuses.

    Main Methods:

    • Review of paranasal sinus anatomy, including nasal cartilages and turbinates.
    • Description of the paranasal surgical box and its vertical component.
    • Discussion of normal anatomy and common anatomical variants.

    Main Results:

    • The paranasal surgical box is bounded by the middle turbinate, orbital wall, and skull base.
    • The vertical component defines frontal recess boundaries, aiding dissection.
    • Application of the surgical box concept ensures complete dissection and prevents complications.

    Conclusions:

    • The paranasal surgical box provides a framework for safe and complete endoscopic sinus surgery.
    • Understanding these anatomical limits optimizes surgical outcomes and post-operative management.
    • This approach facilitates maximal delivery of topical therapies and avoids mucous recirculation.
