Tongue reconstruction remains a major aspect of head and neck reconstructive procedures. Surgeons planning tongue reconstruction should consider several factors to optimize the overall outcomes. Specifically, various technical aspects related to tongue reconstruction have been found to affect the outcomes. Multidisciplinary teams dedicated to oncologic, reconstructive, and rehabilitative approaches play an essential role in the reconstructive process. Moreover, operative planning addressing certain patient-related and defect-related factors is crucial for optimizing functional speech and swallowing, as well as quality of life outcomes. Furthermore, tongue reconstruction is a delicate process, in which overall functional outcomes result from proper flap selection and shaping, recipient vessel preparation and anastomosis, surgical approaches to flap insetting, and postoperative management. The second part of this review summarizes these factors in relation to tongue reconstruction.

Tongue reconstruction after oncologic resection with free flap is important to conserve function and shape. Vertical rectus myocutaneous free flap is usually used for total tongue reconstruction, but our patient was thin and primary closure after flap elevation seemed hard. So we used anterolateral thigh free flap to reduce donor site morbidity and to maintain bulk of the tongue as much as possible. Deepithelization of both middle side of flap and folding was done to mimic normal tongue base's shape and volume. Flap survived without complication and patient underwent concurrent chemoradiation therapy three weeks after surgery. Anterolateral thigh free flap can be good candidate for total tongue reconstruction especially in thin patient.

Background: Tongue reconstruction is challenging with the unique function and anatomy. Goals for reconstruction differ depending on the extent of reconstruction. Thin and pliable flaps are useful for tongue tip reconstruction, for appearance and mobility. This study reports lateral arm free flap (LAFF) as a safe and optimal option for hemi-tongue reconstruction, especially for tongue tip after hemiglossectomy. Methods: Thirteen LAFFs were performed for hemi-tongue reconstruction after hemiglossectomy from 1995 to 2018. Of the 13 patients, seven were male and six were female, age varying from 24 to 64 years. Results: All flaps healed uneventfully without complications. Donor sites were closed primarily. The recipient vessels for microvascular anastomosis were mainly superior thyroidal artery, external jugular vein. All patients returned to normal diet, with no complaints regarding reconstructed tongue and donor site. Conclusion: The LAFF is hairless, thin (especially with lateral epicondyle approach), and potentially sensate. They are advantageous features for tongue tip and hemi-tongue reconstruction. Donor site sacrifices the inessential posterior radial collateral artery, and the scar is hidden under short sleeve shirts. We believe that LAFF can be considered as the first choice flap for hemitongue reconstruction, over radial forearm free flaps.

Purpose: Advanced carcinoma of the tongue is a devastating disease which may cause severe speech or swallowing dysfunction. But, none to date has provided all of the complex functions of the tongue. The purpose of this study is to review our experiences with individuals who underwent glossectomy followed by reconstruction using free tissue transfer. Methods: Between February 1998 and February 2005, twenty-four patients underwent glossectomy followed by free tissue transfer reconstruction. The defects of tongue caused by partial or subtotal glossectomy were reconstructed by means of radial forearm or lateral thigh free flap with nerve innervation. Especially for the patients who underwent total glossectomy, we reconstructed deglutition muscles anatomically with nerve reinnervation, a procedure that allows the grafted muscle to maintain good tongue bulk without obvious atrophy. Results: Patients were reviewed to determine their functional outcome as it related to speech, deglutition, and aspiration. All patients achieved oral intake of a soft diet and acceptable speech. Conclusion: Although reconstruction following glossectomy using free tissue transfer is not ideal, this procedure is safe and reliable, and provides predictable results. A future challenge is the development of a surgical procedure for reconstruction of a tongue that maintains mobility and sensation using neurotized flaps.

Reconstructive surgery in the management of head and neck cancer has evolved to include structure-specific approaches in which organ-specific treatment algorithms help optimize outcomes. Tongue cancer management and reconstruction are surgical challenges for which well-executed reconstructive plans should be completed promptly to avoid delaying any subsequently planned oncologic treatment. Crucial considerations in tongue cancer resection are the significant functional morbidity associated with surgical defects, particularly in terms of speech and swallowing, and the consequent negative impact on patients' quality of life. With the evolution of microsurgical techniques and the development of the perforator flap concept, flap options can be tailored to the characteristics of various tongue defects. This has allowed the implementation of pliable flaps that can help restore tongue mobility and yield subsequent functional outcomes. Using an evolutional framework, we present this series of reviews related to tongue reconstruction. The first part of the review summarizes flap options and flap-related factors, such as volume and tissue characteristics. Related functional aspects are also presented, including tongue mobility, speech, and swallowing, as well as ways to evaluate and optimize these outcomes.

After total glossectomy, recovery of swallowing and speech function can greatly improve quality of life. The reconstructed tongue must be thick enough to contact with the hard palate for articulation. If the free flap is denervation, it may procede to have atrophy postoperatively. Therefor it is difficult to maintain the tongue volume for a long period of time. To resolve this problem, we have used a innervated rectus abdominis musculocutaneous flap and maintaining the volume through a neurorrhaphy. 7 patients underwent immediate reconstruction using a reinnervated rectus abdominis musculocutaneous free flap in which included intercostal nerve was anastomosed to the remaining hypoglossal nerve. The reinnervated rectus abdominis musculocutaneous free flap has provided good tongue contour with sufficient bulk and shown no obvious atrophy in all patients even though postoperative 9 months later. Considering swallowing and articulation, we concluded that reinnervated rectus abdominis musculocutaneous flap is a viable method after total glossectomy

Purpose: Tongue cancer is the most common malignant tumor of the oral cavity and the ultimate goal in treatment of the cancer is not only complete excision and meticulous closure of the wound, but also, reconstruction of a demensional and functional tongue. Our study focuses on various factors, such as defect size, extent of tumor, age, application of mandibulectomy or radiotherapy, and their influences on postoperative speech and swallowing function. Methods: Our study was based on 59 patients who underwent tongue cancer operation and reconstruction of the tongue. Speech and swallowing were evaluated according to categories documented by Sultan and Teichgraeber. Patients were classified into 3 groups as partial glossectomy, hemiglossectomy and total glossectomy groups for evaluation. The average age of the patients were 51, and the mean follow-up period was 4 years 2 months. Results: The partial glossectomy group showed statistically relevant results for speech articulation and swallowing abilities compared to the total glossectomy group. In cases of defects involving the mouth floor, the group showed decreased results compared to the group without mouth floor involvement. Increased age showed decreased postoperative results with statistical significance, while mandibulectomy and radiotherapy revealed no statistically significant data. Analysis according to TNM staging resulted in decreased functional result with advanced staging without statistical significance. Conclusion: To summarize the factors influencing the functional outcome in tongue reconstruction, younger patients and early stage cancer with minimal surgical extent revealed more satisfying results while mandibulectomy and radiation did not have influence on our analysis. Addition of various influencing factors and studies with longer follow up periods on our patient groups may provide effective data for more satisfying functional outcomes in the future.

Background and Objectives The purpose of the present study was to evaluate the usefulness of a posterior-based buccinator myomucosal flap (the Bozola flap) for the reconstruction of oral cavity defects after tongue cancer resection. Subjects and Method Fifteen patients who underwent from 2014 to 2016 reconstruction of the oral cavity with a Bozola flap after surgical management of tongue cancer were enrolled in the study. Patient characteristics, surgical outcomes, and complications associated with the Bozola flap were evaluated. Results The flap was successfully harvested and transferred in all patients. The mean flap harvesting time was 25.3 min. The donor site was closed primarily in 14 patients, and a buccal fat pad flap was used in one patient. Although partial necrosis of the flap occurred in two patients, no other major complications were noted. Conclusion The results of this study demonstrate that the Bozola flap is a good option for reconstruction of moderate sized oral cavity defects in tongue cancer patients.

Purpose : Anterolateral thigh and radial forearm flap is the most important fasciocutaneous flap widely used for reconstruction of tongue. One important purpose of flap is replacing the volume of tongue but still there is no data about the surface area and volume to be reconstructed after glossectomy. In this paper, surface area and volume is estimated from the 3-dimensionally reconstructed MRI images to see which flap is more ideal and to give the reference value for reconstruction. Materials and Methods : With coronal MRI image, tongue including only the intrinsic muscle is delineated in every section and reconstructed 3-dimensionally and calculated the volume and surface area to be reconstructed according to the degree of glossectomy. This volume and surface area was compared with the volume of anterolateral thigh and radial forearm flap. Results : The volume and surface area to be reconstructed in hemiglossectomy was $39.0{\pm}4.0cm^3$ and $31.8{\pm}2.7cm^2$ respectively. The average thickness of anterolateral thigh flap is $9.4{\pm}2.8mm$ and that of radial forearm is $3.8{\pm}1.0mm$. Comparing the curve of tongue surface area and volume with the volume of flap, the anterolateral thigh flap has more ideal volume to replace the defect. Conclusions : The surface area and volume requested for reconstruction could be suggested and the anterolateral thigh flap has more ideal volume for reconstruction of glossectomy defect.

Objectives : Ablation of carcinoma of the tongue leads to deficits in speech and swallowing, but none to date has provided all of the qualities of mobility and sensation to simulate the complex function of the tongue. The authors evaluated postoperative swallowing and pronouncing function in patients who underwent tongue reconstruction using free flap. Material and Methods : This is a retrospective review documenting the outcome of 42 patients between January of 1991 and August of 2008. We classified patients according to the size of resection of the tongue like as 7 partial glossectomy, 25 hemiglossectomy, 2 subtotal glossectomy, and 8 total glossectomy. Swallowing function was graded into 4 point scale and pronouncing function was analyzed using picture consonant articulation test. Aspiration was evaluated with videofluoroscopic swallowing study. Results : The average points for swallowing function were 3.43 in partial glossectomy, 3.52 in hemiglossectomy, 3 in subtotal glossectomy, and 2.63 in total glossectomy. The percentage of consonants correct showed 76.5% in partial glossectomy, 72.29% in hemiglossectomy, 47.69% in subtotal glossectomy, and 29.94% in total glossectomy. Aspiration was noted in 3 patients(1 hemiglossectomy and 2 total glossectomy) and 2 total glossectomy patients were taken permanent feeding gastrostomy. Conclusion : Free flap gave us proper volume in tongue reconstruction and showed good result in preserving swallowing function. Swallowing function difference according to the size of defect showed no statistical significance, whereas articulation function was shown to decrease in accuracy as the size of defect was larger.
