Pharynx01:20

Pharynx

8.2K
The pharynx, a tubular structure framed by skeletal muscle and lined with mucous membrane, extends continuously from the nasal cavities. It is segmented into three major areas: the nasopharynx, oropharynx, and laryngopharynx.
Nasopharynx
The nasopharynx, bordered by the conchae of the nasal cavity, serves exclusively as an air conduit. In its superior region, the pharyngeal tonsils or adenoids are located. These tonsils are clusters of lymphoid reticular tissue akin to a lymph node. The precise...

Anatomy of Respiratory System I: Upper Respiratory Tract

6.1K
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....

Primary Lymphoid Organs01:16

Primary Lymphoid Organs

16.4K
Primary lymphoid organs are pivotal in the formation, development, and maturation of lymphocytes, the white blood cells that serve as the backbone of our immune system. This crucial function underscores their fundamental role in maintaining our overall health and immunity. The two primary lymphoid organs of prime importance are the red bone marrow and the thymus.
The red bone marrow is a soft, spongy tissue nestled in the interior of long bones such as the humerus and femur. It is the site...

Chronic Pharyngitis01:23

Chronic Pharyngitis

14.0K
Chronic pharyngitis refers to persistent inflammation of the pharyngial mucosa.
Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...

Acute Pharyngitis01:30

Acute Pharyngitis

5.2K
Introduction
Acute pharyngitis is the inflammation of the back of the throat (pharynx), commonly resulting in a sore throat. It is a frequently encountered condition that prompts individuals to seek medical advice.
Classification
Acute pharyngitis can be categorized based on its underlying cause:

Trachea01:22

Trachea

5.8K
The trachea, commonly known as the windpipe, is a vital part of the human respiratory system. It serves as a passageway for air to travel between the larynx and the bronchi, allowing oxygen to reach the lungs. Let's explore its anatomical features, dimensions, layers of the tracheal wall, associated muscles, and the functions of its parts.
Anatomical Features:
Location: About half of the trachea is situated in the neck, anterior to the esophagus, and extends from the larynx (at the level of...

Summary

Surgical removal of parapharyngeal space tumors is effective, with most being benign. The transcervical approach is most common, and complications are infrequent.

Area of Science:

  • Otolaryngology
  • Head and Neck Surgery
  • Surgical Oncology

Background:

  • The parapharyngeal space (PPS) is a complex anatomical region in the head and neck.
  • Tumors originating in or involving the PPS require specialized diagnostic and surgical expertise.

Purpose of the Study:

  • To present surgical experience with diagnostic and therapeutic strategies for parapharyngeal space tumors.
  • To analyze the types of tumors, surgical approaches, and outcomes in patients with PPS tumors.

Main Methods:

  • Retrospective review of 90 patients surgically treated for PPS tumors between 1984 and 2015.
  • Exclusion of secondary invasions, deep parotid lobe tumors, and metastatic disease.
  • Analysis of tumor histology, surgical approach, and postoperative complications.

Main Results:

  • 74% of PPS tumors were benign, with pleomorphic adenoma (27%) and paragangliomas (25%) being most common.
  • Malignant tumors accounted for 26% of cases.
  • The transcervical approach was most frequently used (56 cases), followed by cervical-transparotid and infratemporal fossa approaches. Nerve injuries were the most common complications.

Conclusions:

  • Surgical resection of parapharyngeal space tumors can be performed with low complication and recurrence rates.
  • The transcervical approach is a versatile and frequently utilized method for accessing and removing PPS tumors.
