Surgical voice restoration by valved tracheoesophageal fistula is undoubtedly the most successful method of voice restoration for laryngectomy patients, is one of the most important developments in head and neck surgery, and has resulted in a greatly enhanced quality of life for most patients who have undergone this debilitating procedure. In developed countries, it is now unacceptable to perform laryngectomy without giving patients the opportunity to undergo surgical voice restoration. Successful voice acquisition should be achievable in approximately 80% of patients. Success rates will be highest and problems most effectively dealt with under the auspices of a properly organized surgical voice restoration program within a specialist head and neck cancer unit with a well structured specialist multidisciplinary team. This article reviews recent publications addressing indications for surgical voice restoration by tracheoesophageal puncture, expected success rates, and reasons for failure and complications and ways to manage them in the context of the author's own experience.

Advanced laryngeal and hypopharyngeal carcinomas involving the subglottis carry a significantly elevated risk of thyroid gland invasion compared with those that spare this subsite. The overall incidence of thyroid gland invasion is low, and therefore, thyroidectomy should be reserved for cases considered to be at risk as opposed to a being a routine measure for all total laryngectomies.

Premalignant conditions affect the larynx. Dysplasia can progress in severity resulting in cancer depending on many clinical, pathological and molecular factors. The purpose of this study was to examine the expression of the p21 and p27 cyclin-dependent kinase inhibitors and p53 tumour suppressor gene in dysplasia of the larynx. A total of 114 cases of untreated dysplasia were selected from the archives of the University of Newcastle. p21, p27 and p53 immunohistochemistry was performed and the cases followed up. Twenty-eight dysplasias (24%) subsequently developed into cancers. Expression of the molecular factors studied was not associated with cancer progression. p53 expression was associated with smoking (P = 0.005). In contrast, grade of dysplasia was significantly associated with cancer risk (odds ratio 6.7; P = 0.0001). The majority (75%) of cancers were detected within 12 months of dysplasia being diagnosed.

Patients with advanced and recurrent laryngeal and hypopharyngeal cancer often need combined therapy, which is associated with greater morbidity than single modality treatment. The aim of this study was to assess the quality of life in laryngectomees and to assess whether differences exist between the irradiated and the non-irradiated patients. The University of Michigan Head and Neck Quality of Life questionnaire, a validated instrument for assessing the head and neck cancer related functional status and well-being, was used for this purpose. Subjects for the study included patients who had undergone total laryngectomy for laryngeal or hypophyarngeal squamous cancer. No significant difference between the groups was evident in the various domain scores, although a trend towards higher scores was seen in the combined therapy group. This study suggests that long-term side effects induced by radiotherapy do not adversely affect the quality of life in laryngectomised patients.
