Surgical Ciliated Cysts in Orthognathic Surgery.

Surgical ciliated cysts (SCC) are rare entities that were first described in the Japanese literature after treatment for chronic maxillary sinusitis. Classically associated with surgery to the maxillary sinus, they have also been reported in association with orthognathic surgery, bone grafting, and trauma. These lesions can develop from a few months up to several years after the surgical procedure.

Study of condylar positional changes after sagittal split osteotomy for mandibular advancement: A prospective cohort study.

Purpose: To analyse the possible morphologic and positional changes of the mandibular condyles after orthognathic surgery.

Material And Methods: A prospective cohort study was performed. Patients with mandibular retrognathism were surgically treated to advance the mandible.

Transverse maxillary distraction in patients with periodontal pathology or insufficient tooth anchorage using custom-made devices.

Purpose: We present our experience using modified Hyrax devices for treating transverse deficiencies of the maxilla in adult patients with periodontal pathology or insufficient tooth anchorage. The surgical technique, clinical indications, and results are discussed.

Materials And Methods: Eight adult patients (6 females, 2 males) requiring maxillary expansion were studied prospectively between July 2002 and July 2007.
