About this trial

This is an interventional supportive care trial for Surgical Complication focused on measuring Paresthesia, BSSO, Bilateral Saggital Split Osteotomy, Unfavorable split, Unfavorable fracture, Inferior Alveolar Nerve, Reciprocating Saw, Ultrasonic Saw, Pair matched, Randomized Control Trial

Eligibility Criteria

undefined - 45 Years (Child, Adult)All SexesAccepts Healthy Volunteers

Inclusion Criteria:

  • Must be undergoing bilateral sagittal split osteotomy surgery with Dr. Saghezchi at UCSF
  • Must agree to return for all follow up visits.
  • Must not have any preexisting V3 nerve paresthesia
  • Must be below the age of 45.

Exclusion Criteria:

  • Persons with preexisting V3 nerve paresthesias
  • Pre-pubertal children will be excluded (per routine practice for this type of surgery).
  • Patients with syndromic genetic conditions that demonstrate clearly different anatomy in the two sides of their jaws will be excluded since the two sides may not be "exchangeable".

5. Study Description

Brief Summary
The aim of this prospective study is to analyze the postoperative paresthesias experienced in patients who undergo bilateral sagittal split osteotomies (BSSO) using an ultrasonic saw, versus a reciprocating saw. Patients included in the study are ages 15-45 scheduled to undergo BSSO surgery at the University of California, San Francisco. One side of the patient's mandible will be instrumented with either the Stryker Sonopet ultrasonic saw or traditional reciprocating saw, while the other side will receive the remaining intervention (determined via randomization on the day of surgery). Patient paresthesias will then be analyzed on each side for 3 months postoperatively (at postoperative days: 1, 7, 14, 28, and 84). Sensory examinations will be carried out by blinded examiners using von Frey hairs and two point discrimination testing. Patients will also subjectively rate their sensation on each side. The results will then be analyzed to determine if patient paresthesias, including the severity and duration, differed depending on which instrument was used, the ultrasonic or reciprocating saw.

Primary Purpose
Supportive Care
Study Phase
Not Applicable
Interventional Study Model
Parallel Assignment
Model Description
A matched-pair (with-in person) RCT design will be used, wherein one mandibular side (right versus left) in each patient will be randomized to be treated with Sonopet ultrasonic device (with the remaining side being treated with reciprocating saw). Neurosensory impairment, as herein described, will be compared at various post-operative times for a total follow-up of 3 months for each patients. Patients and the researchers examining patients post-operatively will be blinded.
Masking

Masking Description
Patients and providers assessing postoperative nerve functioning are blinded to which side of the mandible received which intervention
