Infinitesimal Peri-angular Pterygomasseteric Transectioning Approach (IPPTA) for the Base Fractures of the Mandibular Condyle: A Preliminary Study



To investigate a reliable and safe surgical access to the condylar base region with minimal surgical trauma to the surrounding anatomic structures. In an attempt to do so, to describe Infinitesimal Peri-angular Pterygomasseteric Transectioning Approach (IPPTA) for the management of base fractures of the mandibular condyle.

Materials and Method

A preliminary clinical study involving 20 patients was undertaken to treat patients with unilateral condylar base fracture of the mandible using IPPTA under general anaesthesia (GA). Various parameters assessed were adequacy of surgical access, wound healing at the incision site, marginal mandibular nerve injury, diet intake and complications post-operatively.


This method provided adequate exposure to fractured condylar base for open reduction and internal fixation (ORIF) with uneventful post-operative recovery phase. There was no limitation to function which was identified by restoration of normal pre-trauma diet intake by 14th post-operative day in more than 50% of the study patients. No complications were observed in any patients among the study population.


The peri-angular approach has been discussed in the literature. The IPPTA highlights the use of a smaller incision providing an adequate exposure to the condylar base region for ORIF.
