Research summary
Retrospective study looking at changes in the nasolabial soft tissues both clinically and radiographically for adult patients undergoing fixed braces combined with upper jaw surgery. One single maxillofacial surgeon's work would be looked at to compare the effects of changes in the nose width post surgery. The stability of a certain stitch used surgically to prevent widening of the nose post surgery will be looked at and this will be followed up long term to determine any changes in the nose width over time. The changes in the angle of the nose tip would also be analysed radiographically and additionally if there is any correlation between the nose width changes and the upper lip height. This will be for St George's patients undergoing jaw surgery who have had measurements recorded as part of their routine appointment pre surgery by the surgeon. These three measurements will have been taken pre surgery (T1), immediately after jaw movement during surgery (T2), and immediately after the stitch has been placed post surgery (T3). The same measurements will be taken at the patients follow up visits as part of their routine clinical examination performed by that surgeon (T4). Lateral cephalometric radiographs taken as part of their treatment will be traced pre and post surgery by the same examiner to identify changes in lip height and nasolabial angle. This will aim to identify the soft tissue changes in the nose and the stability of the stitch (Cinch suture) in maintaining the desired width of the nose. This then will allow clinicians to prepare the patient for possible soft tissue changes both short and long-term.
