[Luschka's or Thornwald's pharyngeal bursa]

Area of Science:

• Otorhinolaryngology
• Anatomy
• Pathology

Background:

• The pharyngeal bursa is an anatomical structure.
• Its location is supero-posterior in the nasopharynx.
• It is situated near the pharyngeal tonsil.

Purpose of the Study:

• To describe the anatomical location and potential pathology of the pharyngeal bursa.
• To explain the development of Thornwald's cyst.

Main Methods:

• Anatomical description.
• Pathological analysis of cyst formation.

Main Results:

• The pharyngeal bursa is located in the supero-posterior nasopharynx.
• Occlusion of its orifice can lead to cyst development.

Conclusions:

• Thornwald's cyst is a pseudotumoral cyst resulting from pharyngeal bursa occlusion.
• Understanding this anatomical variation is crucial for diagnosis.
