Orthognathic surgery

Date of Operation:

17th May 2012

Name of Doctors/Sergeon:

Dr Abdullah Al Masud

Case Study:

People today usually recognize irregular teeth or obvious jaw deformities and seek treatment from an orthodontist, who can improve tooth alignment, function & facial aesthetics. Correction of more severe deformities requires a combination of orthodontics & surgery. Poorly aligned jaws can result in a variety of problems including aesthetic, chewing, breathing & speech problems. Orhtognathic surgery is an operation to reposition the jaws. The surgery aims to correct imbalance between the upper and lower jaws which will enable the teeth to bite together correctly. This surgery also has the benefit of balancing & enhancing the facial appearance. The goal of orthognathic surgery is to obtain a functional occlusion along with correction of underlying skeletal disharmony & giving a maximum aesthetic result without compromising occlusal or skeletal stability. The presenting case is a severe facial deformity along with retruded chin, short mandible, ear tag. Patient also has sleep disturbance.

Progress Step by Step:



 A case of severe facial deformity along with retruded chin, short mandible, ear tag. Patient also has sleep disturbance.

 Her lateral cephalometry shows deep over bite, proclination of upper anterior segment, increased over jet, accentuated curve of spee, short mandible.

 Her orthopantomogram shows skeletal deformity in both ramus, apical pathology in lower left 1st molar. One of the upper central incisor is broken .

 Cephalometric tracing from the cephalometry for treatment planning.

 Cephalometry after completion of the presurgical-orthodontic treatment.

 Final tracing from the cephalometry after completion of the presurgical-orthodontic treatment. From this tracing VTO (virtual treatment objective) will produce.

 This VTO shows the amount of bone repositioning and the changes of facial profile, which is very much satisfactory in this case.

 It is treated by Le-Fort-1 osteotomy with superior repositioning of maxilla and Bilateral Sagital Split Osteotomy along with sliding genioplasty . The external ear tag also removed. This picture demonstrates the final outcome as well as aesthetic changes.

Recommendation:

Orthognathic surgery is not a subject of fear today. Good planning, Communication & free flow of information between the surgeon and patient facilitate efficient and successful treatment and ensure patient confidence
