Choanal adenoid syndrome--a preliminary report
Acta Oto-Laryngologica. Supplementum
|July 26, 2000
Summary
Ectopic adenoid tissue in the choanae caused long-lasting nasal stenosis in 19 patients. Transnasal forceps removal of this tissue successfully treated all cases, highlighting choanal examination for persistent nasal airway obstruction.
Area of Science:
- Otolaryngology
- Nasal Airway Surgery
Background:
- Nasal stenosis, a narrowing of the nasal passage, can significantly impair breathing.
- Persistent nasal stenosis often necessitates repeated treatments, including adenoidectomy.
- Ectopic adenoid tissue within the choanae is an underrecognized cause of treatment-resistant nasal stenosis.
Purpose of the Study:
- To identify the cause of persistent nasal stenosis in patients refractory to standard treatments.
- To evaluate the efficacy of transnasal surgical removal of ectopic choanal adenoid tissue.
Main Methods:
- Retrospective review of 19 patients with chronic nasal stenosis.
- Diagnosis of ectopic choanal adenoid tissue via fiber optic endoscopic examination.
- Surgical removal of choanal adenoid tissue using transnasal forceps.
Main Results:
- All 19 patients presented with long-lasting nasal stenosis despite prior treatments.
- Ectopic adenoid tissue within the choanae was identified as the causative factor in all cases.
- Transnasal forceps removal of choanal adenoid tissue resulted in successful treatment for all patients.
Conclusions:
- Ectopic adenoid tissue in the choanae is a significant cause of refractory nasal stenosis.
- Transnasal endoscopic removal is an effective treatment for choanal adenoid tissue.
- Fiber optic endoscopic examination of the choanae is crucial for diagnosing persistent nasal airway obstruction.

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

01:23Chronic Pharyngitis
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,...

01:30Tonsillitis I: Introduction
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.

01:29Suctioning 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.

01:27Esophageal Achalasia
Esophageal achalasia is a chronic neurogenic disorder characterized by impaired relaxation of the lower esophageal sphincter (LES) and absent or ineffective peristalsis in the distal esophagus. This leads to a functional obstruction without a physical blockage, despite significant disruption of esophageal motility.EtiologyAchalasia is caused by degeneration of the myenteric (Auerbach's) plexus, specifically the loss of inhibitory ganglion cells that produce vasoactive intestinal peptide (VIP)...
