Quality of life after free-flap tongue reconstruction.

OBJECTIVE: To analyse correlations between quality of life measures, aspiration and extent of surgical resection in patients who have undergone free-flap tongue reconstruction. PATIENTS AND METHODS: Nine consecutive patients (seven men and two women; average age 51 years) who had been diagnosed with T4a carcinoma of the mobile tongue and/or tongue base and treated by glossectomy, free-flap reconstruction, and either radiation therapy or chemoradiation responded to the European Organization for Research and Treatment of Cancer Head and Neck-35 questionnaire, the performance status scale questionnaire and the hospital anxiety-depression scale questionnaire, an average of 43 months after treatment (range 18-83 months). Aspiration was evaluated by fibre-optic laryngoscopy. Correlations between quality of life domain scores, extent of surgery and the presence of aspiration were evaluated using non-parametric statistical analysis. RESULTS: Scores for the swallowing and aspiration domains of the European Organization for Research and Treatment of Cancer Head and Neck-35 questionnaire were significantly correlated with the extent of tongue base resection (Spearman's correlation, p = 0.037 and 0.042, respectively). Despite a strong correlation between the European Organization for Research and Treatment of Cancer Head and Neck-35 questionnaire results and the performance status scale global scores (correlation coefficient = 0.89, p = 0.048), the performance status scale domain scores were not correlated with the extent of tongue resection. Clinically apparent aspiration was not correlated with the extent of tongue resection, nor were the anxiety or depression scores. However, clinically apparent aspiration was significantly related to the swallowing and aspiration domain scores of the European Organization for Research and Treatment of Cancer Head and Neck-35 questionnaire (p = 0.017 in both cases). CONCLUSIONS: Our results imply that the volume of tongue base resection is a major factor in swallowing- and aspiration-related quality of life following tongue resection and free-flap reconstruction. Free-flap reconstruction does not seem to palliate the effect of the loss of functional tongue base volume, as regards swallowing-related quality of life.

[Swallowing study with kinetic MRI using a single shot fast spin echo sequence in healthy volunteers and patients treated for head and neck cancer]. / Etude de la déglutition par ciné-IRM utilisant la séquence single shot fast spin écho (SSFSE) chez des volontaires sains et des patients traités pour un cancer ORL.

PURPOSE: To evaluate the single shot fast spin echo sequence (SSFSE) rapid MRI sequence for swallowing study, to describe the swallowing phases analyzable by kinetic MR Imaging and to show the advantages and the limits of the method in patients treated for head and neck cancer. METHODS AND MATERIALS: A preliminary study was conducted in 8 healthy volunteers and 11 patients treated for a head and neck cancer between June 1999 and April 2001. Examinations were obtained on a 1.5 T machine using a multi-slice SSFSE sequence with an acquisition time of 1 second/slice. The different phases of swallowing were analyzed. Examinations were done with and without water ingestion. RESULTS: Kinetic MRI allows to clearly analyze the anatomy and the dynamic of the tongue, the soft palate, the hyoid bone, the larynx and the posterior pharyngeal wall. The hypopharyngeal and esophageal phases were suboptimally assessed. CONCLUSION: Kinetic MRI allows to clearly analyze the oral and early pharyngeal phases of swallowing, which can be correlated with normal and surgically reconstructed areas in spite of the low temporal resolution and the non-physiologic position. It is simple and rapid to perform and may be useful in treated patients with head and neck cancer.
