[Factors influencing morphology and function of the pharynx and pharyngoesophageal sphincter after total laryngectomy. Part II. The impact of degenerative changes in the neck segment of the vertebral column on the rest pressure within pharyngoesophageal sphincter after laryngectomy].
Radiological examinations of the vertebral column neck segment were done in 41 patients after total laryngectomy (n = 29) and laryngopharyngectomy (n = 12). Degeneration changes of different degree (from I degree to IV degree) were stated in 37 cases. Criteria of assessment were as follows: a) the width of the intervertebral space b) appearance and degree of the exostoses c) the length of the degenerative process in vertebral segment of the neck. The advanced degenerative changes in the vertebral column (IV degree) included all neck segment and were characterized by significant narrowing of the intervertebral spaces and exostoses longer than 0.5 cm. These changes were seen statistically more often in the patients after 50. The pharyngoesophageal sphincter's (p.e.s.) rest pressure was statistically rising significantly with the degree of the degeneration changes in the vertebral column. The high pressure in p.e.s. (5.7 + 2.85 kPa--43 + 21 mm Hg) was seen only in the cases of the IV degree degree. In the patients with the IV degree degree of degenerative changes in 67% retention of saliva in the hypopharynx was seen. Probably it was due to irritation of the sympathetic part of the autonomic system. The statistically significant correlation between the degree of the degenerative changes and the complains like pain during the head movement and limitation of the neck motion was also observed. In IV degree degree these complains were noted in 57% cases. The results of the investigations prove the hypothesis of influence of the sympathetic part of the autonomic system on the pharyngoesopghageal sphincter rest pressure.
