Repair of oro-antral communication

The patient was referred to our clinic for extraction of upper left molar due to possible communication with the sinus.
Upon extraction communication with the sinus was identified. The socket was thoroughly debrided and a resorbable collagen membrane was used to repair the site. The patient was instructed not to use her removable prosthesis for 2 weeks.

However at post op visit, oro-antral communication was present. The patient was put on antibiotics for 10 days and a surgical repair of the communication took place.
1 month post surgery the site healed uneventfully with no signs of communication or sinus problems.

Thank you,
