[Re-evaluation of 191 larynx cancer surgeries according to the Open Partial Horizontal Laryngectomies classification proposed by European Laryngological Society working committee in 2014]

Swallowing, voice and quality of life of patients submitted to extended supratracheal laryngectomy

Objective

To describe functional and quality of life results after extended supratracheal laryngectomy.

Methods

In the period from September 2009 to January 2018, 11 male subjects were submitted to extended supratracheal laryngectomy. Swallowing abilities were assessed through videofluoroscopy and the clinical scale Functional Communication Measures of Swallowing. The voices were classified by means of the perceptual-auditory analysis Consensus Auditory-Perceptual Evaluation of Voice. All subjects completed a self-assessment questionnaire for voice and swallowing.

Results

Aspiration was found in four patients and all presented stasis in different structures. All subjects in this study were exclusively orally fed and hydrated. In the evaluation of quality of life in swallowing, patients had mean >80 in all areas (83.47 mean of scores). The general degree and the presence of roughness were the highest means present in Consensus Auditory-Perceptual Evaluation of Voice (37.81 and 49.36, respectively). The mean of 33.36 (±22.56) had little impact on quality of life under the perspective of vocal aspects.

Conclusion

After supratracheal laryngectomy, swallowing was sufficiently restored and the quality of life was satisfactory. The voice presents severely impaired quality and preserved oral communication, with low impact on the activities of daily living. All individuals who maintained two cricoarytenoid units presented better functional results in swallowing and voice.

Re-Evaluation of Open Partial Horizontal Laryngectomies at Our Institution According to the New Classification Recommended by the European Laryngological Society

Objective

The aim of this study was to re-evaluate the open partial horizontal laryngectomies (OPHLs) performed at our institution in terms of the new classification of the European Laryngological Society and compare the differences with the new classification system.

Methods

A retrospective analysis of 45 patients diagnosed with T1b, T2, and T3 laryngeal carcinoma who were treated with OPHLs in our department between 2010 and 2016 were conducted.

Results

All supraglottic laryngectomies (31 operations) were classified as OPHL Type 1. Among these, 11 operations required a resection of an additional structure including arytenoid (ARY) in five operations, piriform sinus (PIR) in four operations, the base of tongue (BOT) in one surgery, and ARY + PIR in one patient. Five supracricoid laryngectomies with cricohyoidoepiglottopexy (CHEP), five supracricoid laryngectomies with cricohyoidopexy (CHP), and four near-total laryngectomy operations constituted Type 2 OPHL (7 operations) and Type 3 OPHL (7 operations). Among these operations, two were classified into Type 2b OPHL and four into Type 3b OPHL as the superior margin of incision included epiglottis.

Conclusion

We consider that, this new classification, because it allows understanding the content of the surgery from the related title, will be useful in comparing different series and techniques.
