Maxillary Sinus Precautions (Closure of Sinus Perforation, Oroantral Fistula or Sinus Lift Procedure)

Because of the proximity between the upper back teeth and the sinus, a complication between the sinus and mouth sometimes results from surgery. This complication often heals slowly and with difficulty. You should follow the instructions for a dental extraction (see post-op instructions after extraction of teeth), also some specific precautions for a sinus floor perforation will assist healing and we ask that you faithfully follow them.

  • Take prescriptions as directed (antibiotics, Sudafed, Afrin and pain medications).
  • Do not forcefully spit or use a straw for 7 days.
  • Do not smoke for 14 days.
  • Do not forcefully blow your nose for at least two weeks, even though your sinus may feel “stuffy” or there may be some nasal drainage.
  • Try not to sneeze; it will cause undesired sinus pressure. If you must sneeze, keep your mouth open.
  • Eat only soft foods for several days, always trying to chew on the opposite side of your mouth.
  • Do not rinse vigorously for 2 days. Gentle salt water swishes may be used after the first 48 hours.
  • Slight bleeding from the nose is not uncommon for several days after surgery. Please keep our office advised of any changes in your condition, especially if drainage or pain increases. It is important that you keep all future appointments until this complication has resolved.
