A pharyngeal pouch develops from a herniation of pharyngeal mucosa through Killian’s dehiscence.
Dysphagia and regurgitation of food occur. Large pouches may cause aspiration pneumonia. Pooling of saliva in the hypopharynx may be noted on indirect laryngoscopy. Barium swallow confirms the diagnosis.
Following an endoscopy to exclude an associated carcinoma, the pouch may be excised via an external approach or the wall between the pouch and oesophagus divided endoscopically using a stapling gun.
Distension of the laryngeal saccule can produce an internal or external laryngocele.
Hoarseness or dysphagia may occur. External laryngoceles may produce a swelling in the neck accentuated by performing Valsalva’s manoeuvre. Laryngeal tomograms taken during this manoeuvre will demonstrate the laryngocele.
Following endoscopy to exclude an associated carcinoma, an internal laryngocele can be ‘uncapped’ whilst an external laryngocele is excised through the neck.
