Nose and Nasal Cavity01:24

Nose and Nasal Cavity

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...
Microbiota of the Respiratory Tract01:29

Microbiota of the Respiratory Tract

The human respiratory tract, comprising the upper and lower segments, serves as a critical interface with the external environment. The upper respiratory tract (URT)—including the nostrils, sinuses, pharynx, and oropharynx—is heavily colonized by microbes, while the lower respiratory tract (LRT), composed of the larynx, trachea, bronchi, and lungs, was long thought to be sterile. However, recent molecular studies have revealed that the lungs are not devoid of microbes but act more like...

Anatomy of Respiratory System I: Upper Respiratory Tract

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.
Epistaxis01:30

Epistaxis

Epistaxis, or nosebleeds, occurs when small, swollen blood vessels in the nasal mucous membrane rupture. Typically, the anterior septum is the primary site of occurrence.
Etiology
Possible causes of this condition include high blood pressure, trauma, low humidity, upper respiratory tract infections, allergies, foreign bodies, nasal inhalation of corticosteroids or illicit drugs, excessive use of decongestant nasal sprays, facial or nasal surgery, anatomic malformation, tumors, or systemic...
Suctioning the Nasopharyngeal Airway01:29

Suctioning the Nasopharyngeal Airway

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.

Defense Mechanism Against Infection01:26

Defense Mechanism Against Infection

Natural flora, body system defenses, and inflammation are natural barriers of the body against infectious agents regardless of previous exposure. Normal floras of the human body refer to the microbial population that colonizes the skin and mucous membranes.
In addition, many body organ systems have unique defenses against infection. The skin is an intact, multilayered surface preventing invasion by microorganisms unless impaired. Mucous membranes lining the mouth, nose, and eyelids are barriers...

Summary

Nasal foreign bodies are common in children, with foam being the most frequent type. Most cases in Port Harcourt were successfully managed in the clinic, posing minimal challenges for Otorhinolaryngologists.

Area of Science:

  • Otorhinolaryngology
  • Pediatric Emergency Medicine

Background:

  • Nasal foreign bodies are a frequent pediatric emergency, often presenting to emergency physicians.
  • Untreated or tampered nasal foreign bodies can pose challenges for Otorhinolaryngologists.

Purpose of the Study:

  • To determine the pattern of nasal foreign bodies in Port Harcourt.
  • To document the types of foreign bodies and evaluate management outcomes.

Main Methods:

  • A retrospective study of 134 patients with nasal foreign bodies.
  • Data collected from Ear, Nose, and Throat clinics at UPTH and Benok Consultants Clinic (1993-2000).

Main Results:

  • The male-to-female ratio was approximately 1:1, with the highest incidence in children aged 2-4 years.

  • Foam was the most common foreign body; the right nostril was more frequently affected.
  • Most foreign bodies were removed successfully in the clinic; only 6 required examination under anesthesia.

    • Conclusions:

    • Nasal foreign bodies in children, while causing anxiety, are generally manageable for Otorhinolaryngologists.
    • Prompt management in a clinical setting is effective for most nasal foreign body cases.
