Unlabelled:
Evaluation of voice quality parameters of esophageal speech in different neoglottis forms after total laryngectomy.
Methods:
Presentation of voice analysis of 20 patients, who underwent total laryngectomy. The success of acquiring this technique was estimated by means of a voice analyzing program (pitch, sound-holding, loudness, spectrogram),and by the intelligibility via the telephone. Shape of the different types of neoglottis that developed and its functioning during vocalization and continuous speech were observed by nasal endoscopy. Data obtained from the voice analysis were compared among the observed three different neoglottis forms.
Results:
The average dysphonia index of the 20 patients was 1.67 ± 0.38 (mean ± SD). Nasal fiberoscopic examination revealed three different types of neoglottis forms – a small mucosal button, two mucosal battens, and a mucosal lip. Voice quality of the esophageal speech of the patients with the mucosal button was found to be the closest to normal by subjective and objective acoustical evaluation.
Conclusions:
These findings emphasize the importance of the proper wound closure technique which can facilitate the development of a special button shape neoglottis form and help to acquire esophageal speech with the best quality parameters shortly after total laryngectomy.

Anatomy of the Larynx
The larynx consists of various components, including cartilage, muscles, and vocal cords. Its structure includes three large unpaired cartilages—the thyroid, cricoid, and epiglottis—and three smaller paired cartilages—the arytenoids,...

Etiology
The primary cause of esophageal strictures is long-standing gastroesophageal reflux disease (GERD), accounting for about 70 to 80% of adult cases. Chronic acid reflux can lead to injury and scarring of the esophageal lining, culminating in...

Nasopharynx
The nasopharynx, bordered by the conchae of the nasal cavity, serves exclusively as an air conduit. In its superior region, the pharyngeal tonsils or adenoids are located. These tonsils are clusters of lymphoid reticular tissue akin to a lymph node. The precise...
