    Nasolabial cyst Nasolabial cyst Presentation Transcript

    • Nasolabial cyst Dr T Balasubramanian
    • Synonyms
      • Klestad't cyst
      • Non odontogenic cyst
      • Epithelial inclusion cyst
      • Fissural cyst
    • Characteristics
      • Common in females
      • Always extraosseous in its occurrence
      • Constantly located under ala nasi
      • Asymptomatic
      • No dental displacement
    • History
      • 1882 Zukerland first described this entity. He coined the term nasolabial cyst
      • 1913 Klestadt first proposed the inclusion theory as the cause for nasolabial cyst
      • 1982 Brown Kelly described histological features of nasolabial cyst
    • Clinical features
      • Swelling over face in the nasolabial region
      • Same swelling over floor of the nose
      • Asymptomatic
      • Unilateral nasal block
      • Rarely pain (infection)
    • Histology
      • Nasolabial cyst is a soft tissue mass with epithelial lining filled with fluid
      • It originates from non odontogenic epithelium
      • Lining epithelium can be pseudostratified columnar, cuboidal epithelium or stratified squamous epithelium
    • Theories of nasolabial cyst
      • Theory I :This theory supposes that nasolabial cyst arises from entrapped nasolacrimal tissue
      • Klestadt theory: This theory proposes that these cysts arise form entrapped tissue within naso labial fissures. Hence he coined the term fissural cyst
    • Imaging
      • Coronal CT nose and pns showing nasolabial cyst
      • Anterior cut reveals the cyst
      • Note the non displacement of upper dentition
    • Surgery
      • Nasolabial cysts are ideally treated by surgery
      • Sublabial approach
    • Surgical steps Infiltration
    • Incision
      • Sublabial incision
      • Care should be taken not to rupture the cyst
      • Use of 15 blade is ideal
    • Cyst exposure
    • Cyst could rupture like this
    • Cyst excision
    • Post excision cavity
    • Wound closure with catgut
    • Thank you
