  3. 3. INTRODUCTION  Tongue is a muscular organ situated in the floor of the mouth. It is associated with the function of taste, speech, mastication, deglutition.  It has an oral part that lies in the mouth, & a pharyngeal part that lies in the pharynx.  The oral and pharyngeal parts are separated by a V – shaped sulcus, the sulcus terminalis.

  30. 30. TONGUE FLAPS  Posterior based dorsal flap  Anterior based dorsal flap  Transverse dorsal flap  Perimeter flap  Dorsoventral disposed flap  Ventral based flap
  31. 31. Glossectomy Definition of Glossectomy Partial glossectomy 1/3 or less of tongue Hemiglossectomy 1/3 to ½ of tongue Near total glossectomy ½ to ¾ of tongue Total glossectomy ¾ or greater of tongue
  32. 32. Treatment planning in patients with cancer of the tongue depends on involvement of the floor of mouth, mandible and other surrounding landmarks, the size of the cancer, and the presence of lymph node disease. Oral Cancer may be treated with radiation or surgery, but surgery still remained the favored treatment of primary choice.
  33. 33. For T1/T2 lesion, a transoral partial glossectomy provided adequate margins of resection. This maintains articulation and swallowing function However, even early stage cancer may be associated with rates of nodal metastasis of 30%. Also, an increase in loco-regional and disease free survival after elective neck dissections for clinically tumor negative necks mandates aggressive treatment.
  34. 34. For T3/T4 cancers, a hemiglossectomy or total glossectomy is usually necessary. This is because they usually involve adjacent structures such as the floor of the mouth, tonsillar pillar, and or mandible
  35. 35. As stated before, small defects can be closed primarily Defect size of 1/3 the volume can be closed. Resection of ½ the tongue results in loss of tongue bulk and scar contracture if limited reconstruction option are pursued The decrease in lingual contact with the palate, lip, and teeth can result in impaired articulation and Reconstruction
  36. 36. Therefore larger than 1/3 defects required some form of reconstruction Local flap vs regional flap can be used for this purpose Goal is to achieve mastication, speech, and acceptable aesthetic results Reconstruction
  37. 37. Local flaps Limited amount of tissue Inferior functional results Not useful for tongue defects- can cause limited tongue motions Tongue flap – divide tongue anteriorly and rotate posteriorly Reconstruction
  38. 38. Regional flaps are well vascularized Need single state reconstruction Harvest not too difficult However, they have limited reach, Can be bulky Necrosis at distal end Reconstruction
  39. 39. Pectoralis major Latissimus dorsi Trapezius Sternocleidomastoid Reconstruction
  40. 40. Microvascular flaps can overcome the limitations of regional flaps Forearm Lateral arm Lateral thigh Latissimus dorsi Rectus abdominus Iliac crease Reconstruction
  41. 41. The preferred method of reconstruction of hemiglossectomy to near total is free tissue flaps. Able to select donor site to match requirements of defect Also, donor site may provide tissue that is no subject to locoregion therapy such as radiation. Reconstruction
