“…The condition of the mucosa and musculature surrounding the PE segment is also important as it determines the quality of the voice 28, 29 . Radiation induces fibrosis of the PE segment while a laryngectomy causes scarring and stenosis, both of which affect the vibration of the segment 30 .…”

Objectives/Hypothesis To evaluate the voice and speech outcomes after tubed supraglottic laryngeal closure (TSLC) surgery to treat chronic aspiration after radiotherapy for head and neck cancer. Study Design A retrospective case‐control study. Methods The data of patients who underwent radiotherapy for head and neck cancer and who later required total laryngectomy or TSLC for chronic aspiration between 2004 and 2017 were retrieved from a dysphagia clinic. Preoperative and postoperative voice and speech were assessed by the GRBAS and INFVo rating scales. Control subjects who underwent radiotherapy alone or total laryngectomy with a tracheoesophageal prosthesis for other indications were recruited for comparison. Results Of 15 patients who underwent a TSLC with a mean age of 57.3 years (45–75 years), 13 were male and 2 female. All patients had a history of nasopharyngeal carcinoma. The success rate of speech production using their own larynx following an intact TSLC was 64%. There was no statistically significant difference in voice and speech ratings between preoperative and TSLC subjects on the GRBAS (P = .32) and INFVo scales (P = .57), although the quality of voice appeared to deteriorate after TSLC. However, the INFVo scale for impression, intelligibility and unsteadiness of the voice after TSLC was statistically significantly better than for laryngectomy with tracheoesophageal speech. Conclusions A tubed supraglottic laryngeal closure controls chronic aspiration while preserving the larynx for phonation, and results in a better voice and speech quality than a laryngectomy with a voice prosthesis.

“…The neopharynx must retain some degree of pharyngeal function to allow passage of food and production of alaryngeal speech. Loss of elasticity could result in a patulous passage, and conversely, excessive muscle tone can cause spasms; both conditions are undesirable for swallowing and speech rehabilitation [46,47].…”

Since the first total laryngectomy was performed in the late 18th century, several improvements and variations in surgical techniques have been proposed for this procedure. The surgical techniques employed in total laryngectomy have not been comprehensively discussed to date. Thus, the main objective of this article was to address controversial aspects related to this procedure and compare different surgical techniques used for a total laryngectomy procedure from the beginning to the end.Although the management paradigms in laryngeal and hypopharyngeal squamous cell carcinomas have shifted to organ-preserving chemoradiotherapy protocols, total laryngectomy still plays a prominent role in the treatment of advanced and recurrent tumors. The increased incidence of complications associated with salvage total laryngectomy has driven efforts to improve the surgical techniques in various aspects of the operation. Loss of voice and impaired swallowing are the most difficult challenges to be overcome in laryngectomies, and the introduction of tracheoesophageal voice prostheses has made an enormous difference in postoperative rehabilitation and quality of life. Advancements in reconstruction techniques, tumor control, and metastatic management, such as prophylactic neck treatments and paratracheal nodal dissection (PTND), as well as the use of thyroid gland-preserving total laryngectomy in selected patients have all led to the increasing success of modern total laryngectomy. Several conclusions regarding the benchmarking of surgical techniques cannot be drawn. Issues regarding total laryngectomy are still open for discussion, and the technique will continue to require improvement in the near future.
