 and: Sjogren Syndrome Pathology

 

Lip biopsy of the minor salivary glands of the lip can be used in diagnosis of Sjogren’s syndrome.  Need to provide the pathologist with 3 – 5 minor salivary glands for examination. 

Consent: Lip biopsy under local anesthesia

  potential complications: bleeding, infection, reaction to the anesthetic, damage to adjacent structures.

Potential for development of mucocoele from interruption of adjacent minor salivary gland drainage, numbness in site of biopsy, inadequate tissue for diagnosis

Equipment:

  • Local anesthesia (see below), needles and syringes
  • Minor tray with: 15 blade, pick ups/tissue forceps, Steven’s scissors, Needle driver, Skin hooks, 4-0 Chromic or 4-0 vicrly for closure, Gauze, Cautery (Silver nitrate, Bipolar), Suction with Fraiser tip, Specimen container to send to path, Head light/Surgical light

Room positioning:

  • In oto minor room
  • Upright in dental chair
  • Mayo stand for supplies

Anesthesia: Local

  • Spray benzocaine spray or apply viscous lidocaine on a cotton ball to the lower lip mucosa
  • Inject the lower lip mucosa with 1% or 2% lidocaine with 1:100,000 epiphrine at desired spot of biopsy using a 27 gauge needle (0.5 cc – 1 cc should suffice)

Procedure:

After local anesthetic has set up make a horizontal or vertical incision to the lip’s long axis (surgeon preference) ~ 1 – 1.5 cm on the lower lip mucosa just lateral to midline while having the lip under stretch (assistant may be necessary).  Superficial to the muscle, identify minor salivary glands by the lobular nature.  Remove several readily available glands and place in specimen cup to send to pathology (on formalin).  Achieve hemostasis by holding pressure with gauze, silver nitrate cautery and/or electrocautery.  Close incision with interrupted simple stitch with 4-0 Chromic (1 or 2 stitches should suffice) or horizontal mattress to reapproximate the mucosal edges.  Regular oral care. 

Post op:

No antibiotics or pain medication necessary.

Complications:

Lower lip numbness

 Mucocoele (obstructed drainage to minor salivary gland in lip adjacent scar)

Pain

Non-diagnostic biopsy (variable sensitivity for Sjogren’s syndrome)

    Note: questions persist about reliability and usefulness of lip biopsy (ref Bamba). Others suggest forgoing lip biopsy in that it adds little useful clinical information for those in whom the diagnosis is unlikely or where the diagnosis is clinically obvious (ref Lee 1999).
