Reduction osteoplasty for treating pneumosinus dilatans of the maxillary sinus.

OBJECTIVE

To report a patient with maxillary pneumosinus dilatans and facial deformity treated by reduction osteoplasty and reconstruction.

CASE REPORT

This study describes the successful management of facial deformity in a 17-year-old male with maxillary pneumosinus dilatans. The patient's facial deformity of the maxillary sinus, which had been slowly progressing over a 10-year period, was managed by reduction osteoplasty and reconstruction using the maxillary bone, conchal cartilage and Tutoplast-processed fascia lata via a sublabial approach. This treatment yielded satisfactory functional and aesthetic outcomes.

CONCLUSION

As pneumosinus dilatans of the maxillary sinus is uncommon, there is no established surgical treatment protocol. This surgical technique was less invasive than other described procedures and revealed good cosmetic results.
