About this study

Mandibular body fractures frequently result in inferior alveolar nerve (IAN) and mental nerve injuries which ultimately leads to paresthesia of chin and lower lip area. The objective of this study is to evaluate the efficacy of platelet rich fibrin (PRF) application to mental nerve during open reduction and internal fixation (ORIF) of patients having neurosensory disturbance (NSD) following mandibular body fracture involving mental foramen. The PRF application to mental nerve in mandibular body fractures will not only aid in hard and soft tissue healing but also prove to be a game changer for a holistic healing of a patient rather than separate surgical procedures for nerve repair such as microsurgery, grafting, tissue glues, laser.

Alternate Hypothesis HA= The application of PRF to the mental nerve during open reduction and internal fixation of mandibular body fractures involving the mental foramen significantly improves neurosensory recovery compared to cases where PRF is not applied.

Null Hypothesis HO= The application of PRF to the mental nerve during open reduction and internal fixation of mandibular body fractures involving the mental foramen does not significantly improve neurosensory recovery compared to cases where PRF is not applied.

Read the detailed description

Oral and Maxillofacial surgical procedures such as maxillofacial trauma treatments,TMJ surgeries, cyst enucleation, tumor resection, orthognathic surgeries may result in nerve injuries. Bilateral sagittal split osteotomy can result in damage to IAN nerve. Mandibular fractures can result in damage to IAN/ mental nerve as result of trauma. The frequency of temporary IAN injury is 0.5-5%, whereas permanent injury is <1% and can result in numbness or paresthesia in lower lip and chin area .

The use of PRF may provide a beneficial effect in virtue because it contains several growth factors and may enhance epineurium fibroblast regeneration. PRF has better efficacy than PRP and normal saline (control) in functional nerve recovery (Khojasteh et al.,2016). The use of PRF placement in mandibular body fractures will not only aid in hard and soft tissue healing but also prove to be a game changer for a holistic healing of a patient (Preponement et al.,2013) rather than separate surgical procedures for nerve repair such as microsurgery, grafting, tissue glues, laser.

Limited studies have been done regarding the role of PRF in neurosensory disturbance following mandibular body fractures. The most recent study conducted by Tabrizi et al.(2024) who studied the role of PRF in neurosensory recovery following mandibular body fractures. In this study PRF was placed on IAN between fracture segments. This study had several limitations such as low sample size and there was no direct application of PRF to mental nerve, which may be a factor in NSD. The actual sample size was lower i.e 25 patients as compared to their calculated sample size i.e 30, because 5 patients did not return for follow-up. Our study will provide more significant data related to efficacy of PRF application to mental nerve in patients having neurosensory disturbance following mandibular body fracture involving mental foramen. The PRF application to mental nerve in mandibular body fractures will not only aid in hard and soft tissue healing but also prove to be a game changer for a holistic healing of a patient rather than separate surgical procedures for nerve repair such as microsurgery, grafting, tissue glues, laser.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Platelets rich FibrinOther

    Also called PRF

    PRF is the second generation autologous platelet concentrate that is obtained from patient's own blood in simple and cost effective manner. PRF is comprised of three main specifications. First, the existence of platelets and their active growth factors i.e. platelet derived growth factor (PDGF), vascular endothelial growth factor (VEGF), transforming growth factor (TGF), insulin-like growth factor (IGF) and epidermal growth factor (EGF). Second, the role of leukocytes and cytokines i.e. TNF alpha, IL-6 and IL-1ɓ in anti-inflammatory response and immune modulation. Third, the fibrin meshwork where these platelets, cytokines and growth factors are embedded and subsequently released after a short period

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Neurosensory Recovery

    Neurosensory disturbance in patients following mandibular body fractures involving mental foramen will be assessed using Two-point discrimination as the primary variable. TPD will be recorded as the minimum distance between two pinpricks that patient could recognize at lower lip and chin area. TPD will be performed by placing a sliding caliper on the skin of chin and mucosa of lower lip. Following scoring criteria has been used in literature (khojasteh et al.,2016).

    TPD >20mm = Score 0 14-20mm= Score 1 <14mm= Score 2

    Measured: Patients having NSD following mandibular body fractures involving mental foramen and pre-operative TPD discrimination score '0' or '1' will be selected in this study .TPD discrimination will be recorded; Preoperatively Immediately After six months
