“…There are descriptions of associated complaints with lateral laryngopharyngeal protrusions, classified as diverticula, like dysphagia [1], cervical aching and odynophagia [15], dysphagia and hoarseness [12], dysphagia, suffocation and cervical discomfort [14] and even the possibility of aspiration after swallowing [13,16]. Bagatzounis and Geyer [17] suggested that a lateral pharyngeal protrusion could be the cause of laryngeal superior nerve neuralgia.…”

The aims were to characterize the anatomical region where the lateral laryngopharyngeal protrusion occurs and to define if this protrusion is a normal or a pathological entity. This protrusion was observed on frontal contrasted radiographs as an addition image on the upper portion of the laryngopharynx. We carried out a plane-by-plane qualitative anatomical study through macroscopic and mesoscopic surgical dissection on 12 pieces and analyzed through a videofluoroscopic method on frontal incidence the pharyngeal phase of the swallowing process of 33 patients who had a lateral laryngopharyngeal protrusion. The anatomical study allowed us to identify the morphological characteristics that configure the high portion of the piriform recess as a weak anatomical point. The videofluoroscopic study allowed us to observe the laryngopharyngeal protrusion and its relation to pharyngeal repletion of the contrast medium. All kinds of the observed protrusions could be classified as "lateral laryngopharyngeal diverticula." The lateral diverticula were more frequent in older people. These lateral protrusions can be found on one or both sides, usually with a small volume, without sex or side prevalence. This formation is probably a sign of a pharyngeal transference difficulty associated with a deficient tissue resistance in the weak anatomical point of the high portion of the piriform recess.

“…In agreement with these previous observations, no spontaneous complaints were expressed by the 22 subjects all of them wind instrumentalists with large diverticula. Nevertheless, there are descriptions of complaints associated with lateral laryngopharyngeal diverticula, such as dysphagia (10) , cervical aching and odynophagia (15) , dysphagia and hoarseness (11) , dysphagia, suffocation, and cervical discomfort (9) , aspiration after swallowing (16,28) , laryngeal superior nerve neuralgia (3) , cervical mass (24) , halitosis, and the sensation of a foreign body in the throat (18) . For this reason, all these complaints were directly mentioned to each volunteer, and all of them denied any such complaints.…”

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".

“…Diverticula are uncommon in the EI, and they generally are of 4 types: lateral pharyngeal or laryngopharyngeal diverticulum, [31][32][33][34] Zenker's diverticulum, 35 diverticulum or pseudodiverticulum, 40 and KillianJamieson diverticulum 41-43 (Video 2, available online at www.giejournal.org). Diverticula in the EI and esophagus are best studied by barium esophagram.…”
