  19. 19. Histology <ul><li>Nasolabial cyst is a soft tissue mass with epithelial lining filled with fluid
  20. 20. It originates from non odontogenic epithelium
  21. 21. Lining epithelium can be pseudostratified columnar, cuboidal epithelium or stratified squamous epithelium </li></ul>
  22. 22. Theories of nasolabial cyst <ul><li>Theory I :This theory supposes that nasolabial cyst arises from entrapped nasolacrimal tissue
  23. 23. Klestadt theory: This theory proposes that these cysts arise form entrapped tissue within naso labial fissures. Hence he coined the term fissural cyst </li></ul>
  24. 24. Imaging <ul><li>Coronal CT nose and pns showing nasolabial cyst
  25. 25. Anterior cut reveals the cyst
  26. 26. Note the non displacement of upper dentition </li></ul>

  28. 28. Sublabial approach </li></ul>
  29. 29. Surgical steps Infiltration
  30. 30. Incision <ul><li>Sublabial incision
  31. 31. Care should be taken not to rupture the cyst
  32. 32. Use of 15 blade is ideal </li></ul>
  33. 33. Cyst exposure
