Abstract

Conventional operator position has been followed for many years in routine maxillofacial surgery for surgical removal of mandibular 3rd molar. Henceforth, this study will determine whether the modification in operator stool position will improve the ergonomics as well as comfort of the surgeon to assess the variability in chair position which will increase the comfort of the operating surgeon for mandibular 3rd molar removal and to prove whether this is more convenient than the conventional operators chair position. Surgical removal of impacted mandibular 3rd molar of various types of impacted mandibular third molar (mesioangular, distoangular, horizontal,vertical) on the left and the right side of mandible are operated with the surgeons dental stool position on the same and the opposite side(which is the modification done in this study). A set of questionnaire was given to the operator to assess the ease and the comfort zone of the operator. From the above study it can be concluded that by positioning the operators chair on the same as that of the impacted tooth to be surgically removed i.e., by positioning the operator’s stool on the right side for right 3rd molar extraction and left side for an impacted left molar extraction offers better visualisation, ease in access, increased precision, decreased fatigue, better instrument handling.
