Long-term functional outcomes and quality of life after partial glossectomy for T2 squamous cell carcinomas.

IntroductionPartial glossectomy and reconstruction strategy for malignant tongue tumors influences speech and swallowing.ObjectiveThe aim of this retrospective study was to evaluate long-term functional outcomes after partial glossectomy for pT2 mobile tongue carcinomas with a maximum dimension between 2 and 3cm. Different reconstruction strategies (with or without pedicled flap) were compared.MethodsTwenty-two patients with at least 12 months followup were included. Clinician-based and self-reported instruments were used to analyze tongue motility, speech intelligibility and articulation, swallowing, and quality of life.ResultsPatients with a higher tongue motility had better articulation and lower dysphagia. Avoiding pedicled flap reconstruction seemed to guarantee lower impairment of speech and swallowing. Worse functional outcomes induced a lower quality of life.ConclusionPartial glossectomy results in tongue motility impairment and consequently alterations of oral functions. Since the type of reconstruction impacts long-term outcomes, it should be adequately planned before surgery.
