Tonsillitis I: Introduction01:30

Tonsillitis I: Introduction

3.9K
Tonsillitis is inflammation of the tonsils, which are two lymphoid tissue masses at the back of the throat. This condition can cause discomfort and irritation in the throat.
Etiology
Three primary contributing factors have been identified.

Chronic Pharyngitis01:23

Chronic Pharyngitis

16.6K
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,...

Pharynx01:20

Pharynx

9.5K
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

6.8K
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....

Hiatal Hernia01:25

Hiatal Hernia

60
A hiatal hernia is the abnormal protrusion of the stomach or other abdominal organs through the esophageal hiatus of the diaphragm into the thoracic cavity.Normally, the gastroesophageal junction (GEJ) lies below the diaphragm and is supported by the phrenoesophageal membrane, the diaphragmatic crura, and connective tissues. Weakening of these structures—due to aging, congenital defects like a short esophagus, or increased intra-abdominal pressure from coughing, obesity, pregnancy, or...

Summary

A rare case of persistent Horner syndrome in a child following tonsillectomy highlights the risks of monopolar electrosurgical dissection. This complication, affecting the oculosympathetic pathway, resulted in permanent damage.

Area of Science:

  • Otolaryngology
  • Pediatric Surgery
  • Neurology

Background:

  • Horner syndrome is a rare complication following tonsillectomy.
  • Persistent cases lasting over a month are exceptionally uncommon.

Observation:

  • A 5-year-old child developed persistent Horner syndrome after tonsillectomy.
  • The condition affected the oculosympathetic pathway.

Findings:

  • Pharmacological tests confirmed Horner syndrome.
  • Radiographic imaging revealed damage to the superior cervical ganglion.
  • Conventional monopolar electrosurgical dissection was identified as the cause.

Implications:

  • Monopolar electrosurgery can cause irreversible neural damage to the superior cervical ganglion.
  • This technique may lead to permanent Horner syndrome in pediatric patients.
  • Surgical techniques for tonsillectomy require careful consideration to prevent neural injury.
