Analyses of speech intelligibility in patients after glossectomy and reconstruction with fasciocutaneous/myocutaneous flaps.
This study analyzed the results of speech intelligibility tests in patients with tongue cancer who had undergone resection with the aim of making surgical recommendations for flap design and inset, to improve speech function. A total of 126 patients, enrolled from 13 Japanese institutions, were classified into 3 groups according to the resected site: lateral, anterior, and combined. The lateral group was further divided into 3 subgroups and the anterior group into 2 subgroups according to the size of resection. The speech intelligibility score was analyzed based on articulatory site and mode: 5 articulatory sites (linguodentoalveolar, linguopalatal, linguovelar, and their intermediates); and 7 articulatory modes (plosives, fricatives, affricatives, grids, nasals, vowels and semivowels). Low speech intelligibility scores were recorded at sites where flaps contribute directly to the pronunciation in the lateral and combined groups and at the anterior part of the reconstructed tongue in the anterior group. Plosives and glides displayed low values in general. A radial forearm flap had higher function in the lateral group than other flaps. The type of flap had no effect in the anterior and combined groups. Surgical techniques and flap selection to improve functional status in each type of resection are discussed.
