“…T h e shape o f the pharynx usually reflects the mucosal surface, the cartilaginous and m u s c u l a r skeleton o f the pharynx, and the extrinsic tissues that impinge on the m u c o s a [7]. T h e en face mucosal surface pattern reflects the m ucosa a n d the l y m p h o i d and m u s c u l a r tissue immediately below the mucosal layer.…”

“…Longitudinal striations are occasionally seen on the lateral and posterior pharyngeal walls [7]. T h e s e striations reflect close apposition o f the epithelial layer to the inner longitudinal muscle layer or its aponeurosis [7]. Horizontal striations of mucosa overlying the muscular processes of the arytenoid cartilages or cricoid cartilage reflect redundant epithelium and submucosa in these regions [7].…”

“…This less resistant area is the region of the thyrohyoid membrane, where the internal branch of the superior laryngeal nerve passes to the laryngopharyngeal submucous membrane (6) . Lateral laryngopharyngeal diverticula have been variously considered to be rare (17,23,31) or common (10,20) ; as a pathological entity (1,10,11,22,25,27,28) ; and also as a variation of the normal morphology (2) . They have been described as a pouch or bulge with a narrow or wide neck (10) , and also as true (10) and as false diverticula (6) .…”

CONTEXT: This paper analyze healthy musicians who play wind instruments. OBJECTIVE: To identify possible diverticular formations on the laryngopharyngeal wall produced by pharyngeal overpressure during the use of these instruments. METHODS: Through a videofluoroscopic method, 22 professional musicians had their pharynx analyzed in frontal face and profile, by swallowing 20 mL of barium sulfate solution and blowing against resistance. RESULTS: All the volunteers showed lateral laryngopharyngeal diverticula (3 unilateral and 19 bilateral) with areas ranging from 0.7 to 6 cm². Trumpet and clarinet players showed larger diverticula, on both the right and left sides. Any important complaints were noted spontaneously or after questions. In the barium-swallow analyses, the 41 diverticula previously identified in the blowing tests were not seen or appeared to be smaller, because of the free flux passage from the pharynx to the esophagus. Despite the existence of the other, less resistant areas on the laryngopharyngeal segment, no other protrusions could be found in this group of wind instrumentalists. CONCLUSIONS: The lateral laryngopharyngeal diverticula that occur in blow instrumentalists is distinct of diverticula produced by laryngopharyngeal overpressure determined by abnormally high resistance to flux passage from pharynx to esophagus. In musicians is the persistent and continuous pharyngeal overpressure induced by the resistance of the instrument's mouthpiece will strongly distend the anatomically less resistant areas of the pharynx, producing a large protrusion. Laryngopharyngeal overpressure without abnormal resistance to flux passage explain the way blow instrumentalists protrusions did not appear as full sacs in a barium-swallow test, despite their larger dimensions. As final conclusion the musician-acquired diverticula must be considered as an "occupational overuse syndrome".

“…If possible, the examination shouM be biPhasic. It should include both dynamic recording (eineradiography or videofluoroscopy) for evaluation of function and double-contrast examination for assessment of mucosal detail [4][5][6]8]. Dynamic recording allows the frame-by-frame analysis that Is so necessary in evaluation of a motility disturbance or a lesion seen on only one or two frames of a continuous sequence.…”

Dysphagia

Difficulty in swallowing is not an uncommon symptom. Approximately 10,000 persons choke to death every year in the United States, and at least 50% of patients in nursing homes have some difficulty eating or drinking. Dysphagia will become an increasing problem as the population continues to age, as more intensive resuscitative measures are applied, and as more aggressive head and neck surgery is performed. The practicing radiologist should be familiar with the examination technique and interpretation of swallowing studies.
