title: Oesophageal speech after laryngectomy: a study of possible influencing factors.
abstract: 52 patients with laryngeal carcinoma were studied before and after laryngectomy with regard to what factors might influence the development of oesophageal speech. The investigations consisted of oesophageal manometry, a follow-up interview and a review of surgical approaches and radiotherapy. 43% of the patients achieved socially acceptable oesophageal speech, 22% were able to speak single words, and 35% had no oesophageal speech at all. 61% had post-operative dysphagia. Age was the only factor which significantly correlated to intelligible speech. The intraoesophageal pressure during oesophageal phonation exceeded in all cases the low PO-HPZ pressure after operation. The extension of surgery and radiation field, severity of dysphagia, alcohol and smoking habits, and mental condition did not differ between the 3 groups of oesophageal speech. It was concluded that the rather complicated process of acquiring oesophageal speech is much more dependent on learning ability which decreases with age than on various kinds of motor dysfunction after laryngectomy.
