“…No significant difference was found in preoperative BMI between those with increased and decreased RTFV, consistent with a previous study's findings 15 . The study also found correlation between RTFV change at 6 months postoperative and preoperative triglyceride levels.…”

“…Within 6 months postoperatively, high preoperative triglyceride levels led to a smaller decrease in RTFV, suggesting that RTFV is influenced by the patient's fat percentage. After postoperative 1 year, high preoperative albumin levels led to smaller decrease in RTFV, which suggested that preoperative nutritional status affects RTFV 15 . BMI, triglyceride, and albumin are all nutritional indices.…”

ObjectivesThis study aimed to investigate the relationship between postoperative reconstructed tongue flap volume (RTFV) and body mass index (BMI) and identify factors affecting the flap volume in patients with tongue squamous cell carcinoma.MethodsThirty‐two patients were evaluated for RTFV from computed tomography images and BMI. The first and second evaluations were done at 6 months and 1.5 years after surgery respectively. RTFV rate changes and BMI differences from the first and second evaluations were calculated. The correlation between RTFV rate change and BMI difference was assessed using Spearman's rank correlation coefficient. Multiple regression analysis evaluated the relationship between the flap volume rate change and age, sex, flap type, and BMI difference to identify influencing factors.ResultsThe flap volume rate change and BMI difference correlated significantly (r = .594, p < .05). BMI difference and flap type were independent factors that affected reconstructed flap volume rate change in multiple regression analysis (p < .05).ConclusionThe flap volume of patients with tongue squamous cell carcinoma correlates with the BMI change in the chronic phase. Patients after tongue reconstruction need to be well nourished to maintain BMI and thus postoperative tongue volume to maintain the quality of life.Level of EvidenceLevel 3.

“…However, it is difficult to judge the volume change solely from a photograph. Therefore, most recent studies related to flap volume after head and neck reconstruction have used measurement software 3,7,11–13 . To the best of our knowledge, however, this is the first study targeting only the hemi-tongue reconstruction group.…”

A 3-Dimensional Analysis of Flap Volume Change in Hemi-Tongue Reconstruction

et al. 2022

BackgroundAn adequate volume of the tongue flap is essential to preserve speech and swallowing functions. However, it is generally known that the volume of the free flap tends to decrease over time because of various reasons. Especially in hemi-tongue reconstruction, as half of the normal tongue is retained, some functions are maintained; consequently, there are few studies related to the volume of the flap and function. This study investigated the relationship between flap volume change and function after hemi-tongue reconstruction.MethodsA retrospective chart review of 26 patients who underwent hemi-tongue reconstruction between 2003 and 2020 was performed. Patient demographic data, postoperative radiotherapy (RT), and data on flap types were collected. The volume of the flap was measured by converting the computed tomography and magnetic resonance images into 3 dimensions using the Mimics software. In addition, speech scores and feeding scores were collected.ResultsThe first follow-up computed tomography or magnetic resonance imaging (T1) was performed after an average of 2.09 months, and the second follow-up imaging study (T2) was performed at 16.58 months on average. On average, the T2 volume was 64% of the T1 volume (range, 45.75%–90.54%). Factors including speech and swallowing functions were compared by dividing the group into a group with a more than average decrease in volume (group 1) and a group with a less than average decrease in volume (group 2). In group 1, there were significantly more cases of postoperative RT than in group 2 (85.7%, 50.0%, in group 1 and group 2, respectively; P = 0.049). However, there was no difference in the functional aspects between the 2 groups.ConclusionsThe present study revealed that the flap volume decreased more when RT was performed. However, there was no association between the degree of volume loss and speech and swallowing functions. Regardless of the group, the loss of function was not severe, probably because the remaining half of the tongue was functioning.
