patient satisfaction and objective assessment of neurosensory function following trigeminal nerve repair using allograft
Introduction and objective:
Trigeminal Nerve Injuries can be disruptive, causing intermittent or constant pain, speech difficulties, and other functional issues leading to a decrease in quality of life.
The purpose of this study is to describe the results of only using processed nerve allografts (Avance nerve graft, AxoGen, Inc, Alachua, Fl) to microsurgically reconstruct LN and IAN injuries. This study was also to examine the relationships between subject satisfaction and functional sensory recovery status.
Patients and methods:
A retrospective analysis of subjective neurosensory function of 18 subjects with 20 procedures who underwent LN and IAN nerve grafting was completed.
Neurosensory testing at the preoperative visit and at the post-operative visit was performed(including, Light touch testing, Brush stroke direction, Two-point discrimination testing,Taste test, OHIP questionnaire, Functional Sensory Recovery) all done by the same investigator.
Subjects were classified as achieving functional sensory recovery by the criteria of the Medical Research Council. Subjects completed an Oral Health Impact Profile (OHIP) questionnaire for postoperative patient satisfaction.
The mean duration between injury and repair for LN was 5.45 ±1.38 months and for IAN was 10.55 ± 15.19 months.
The majority of patients (90%) with LN damage regained sensation or taste, with 45% regaining sensation only, 27% partial taste, and 18% full taste.
12 out of 18 (66.7%) patients described their postoperative patient satisfaction in the range of good to excellent.
Functional sensory recovery was achieved in 65% of the nerve sites.
There is a significant positive correlation between improved patient satisfaction and improved neurogenic anesthesia (rho=0.82; P<0.0001).
