Objectives: To use an electroglottography (EGG)-based videostroboscopy tool to assess the anatomical and morphologic characteristics of the pharyngoesophageal (PE) segment in tracheoesophageal (TO) speakers. Study d0 esign: Cross-sectional cohort study. Subjects: Fifty-two post-laryngectomy patients with no recurrence and using prosthetic (Blom-Singer) speech. Intervention: An electroglottography (EGG)-based videostroboscopy tool EGG-based rigid videostroboscopy as well as perceptual evaluation. Outcome m0 easures: Stroboscopic protocol included nine subjective/visual parameters to evaluate the neoglottis and study correlation of the G (GRBAS scale) and the overall voice quality (OVQ) with the treatment variables. Results: Of the 52 laryngectomees, videostroboscopic recordings were possible in 46 patients (36 males and 10 females) with a mean age of 63.4 ±10.5 (SD) an electroglottography (EGG)-based videostroboscopy tool years. All used the Blom-Singer valve and the median time since Total Laryngectomy was 2 years. The neoglottis was assessable in 26 patients. We were able to strobe only 9 patients. There was excellent correlation between G and OVQ (Spearman rho > 0.9). Statistically significant correlation was found between G1 and saliva (P = 0.03) and between good OVQ and saliva (P = 0.02); similarly, there was significant correlation between G1 and LVV (P = 0.05) and between good OVQ and LVV (P = 0.03). Conclusions: This study is the first to examine the use of an EGG-based stroboscopy instrument to evaluate TO speech. Our observations suggest that from the standpoint of functional voice, saliva and the LVV had statistically significant effect in determining voice quality.

Total laryngectomy or laryngopharyngectomy remains the procedure of choice for advanced-stage (UICC T3 and T4) laryngeal carcinoma around the world despite advances in conservative laryngeal surgery and radiotherapy. However, it has profound effects on respiration and deglutition, in addition to the most disabling effect-the loss of verbal communication. Successful voice restoration can be attained with any of three speech options, namely esophageal speech, electrolarynx, and tracheoesophageal (TO) speech using an artificial valve. Although, no single method is considered the best for every patient, the tracheoesophageal puncture has become the preferred method in the past decade. Several types of voice prostheses have been produced since the first prosthesis was introduced in 1980 by Blom and Singer. However, eventually all prostheses are confronted by the same problem, i.e., the development of a biofilm, leading to deterioration and ultimately to dysfunction of the prostheses, necessitating replacement. This article attempts to sum up the historical background as well as the current state of surgical voice rehabilitation following laryngectomy; we review the recent major advances as well as the future prospects. Data was collected by conducting a computer-aided search of the MEDLINE and PubMed databases, supplemented by hand searches of key journals. Over 50 articles published in the last three decades on the topic have been reviewed, out of which about 20 were found to be of relevance for this article.

Quality of life (QOL) is by definition a multi-dimensional global construct that has become an increasingly important outcome measure in cancer treatment. The impact of a head and neck cancer (HNC) diagnosis on the person and the consequences of its treatment cross multiple functional domains that have a clear and direct influence on one’s post-treatment well-being and associated QOL. The evaluation of QOL and performance outcome in cancer is critical to optimal patient care, comprehensive evaluation of treatment alternatives, and the development of informed rehabilitation and patient education services. Despite the difficulties of going from concept to quantification of patient perceptions, the number of instruments available to measure QOL psychometrically has increased rapidly. Assessments can now be made in a variety of distinctive ways using both specific and generic measures. There is no gold-standard questionnaire and the choice is based on psychometric properties, research objectives and study design. QOL assessment has evolved over the years into an organised scientific discipline, such that useful insights can be obtained by a review of the current literature. However, more work needs to be done to improve the applicability and clinical utility of QOL assessment. Most importantly. QOL studies should be reported in such a way as to provide clinically meaningful data to physicians and surgeons, in order to link research to clinical practice. Further attention should be paid to the development of newer theoretical models, minimalist approaches, development of more sensitive and specific instruments and the effective use of modern technology to achieve this objective.

The TNM system of staging cancers is a simple and effective method to map the extent of tumours. It had traditionally strived to maintain a balance between being simple and user-friendly on one hand and comprehensive on the other. A number of revisions have taken place over the years with the goal of improving utility. However, numerous controversies surround the TNM system. There is a school of thought that contends that patient co-morbidity and specific tumour-related factors should be incorporated to add further prognostic capabilities in the TNM system, but this raises concerns that such an approach may unnecessarily complicate the system. This review highlights some controversies that surround the TNM system and suggests prognostic indicators that may be added to make it more useful in guiding treatment decisions and predicting outcomes.
