“…Bai et al showed that short-term craniofacial function impairment in Skeletal Class III patients could be caused by orthognathic surgery, and individuals’ mouth openings were less than they had been preoperatively; however, over time, orthognathic surgery lead to more stable and symmetrical orofacial functions [ 21 ]. Meneses-Santos et al showed the beneficial effects of low-level laser therapy in maximal mouth opening following orthognathic surgery [ 22 ]. Additionally, Joachim et al observed a reduction in mouth opening amplitude.…”

This study aims at evaluating and categorizing patients’ objective and subjective postoperative recovery symptoms after bimaxillary orthognathic surgery assigning the healing process. The patients were monitored throughout the recovery process, and their symptoms were managed. A prospective, observational study was performed. Patients with Class II and III malocclusion (aged 18 to 35) were evaluated and monitored preoperatively, and postoperatively at 48 h, 2 weeks, 1 month, and 3 months postsurgery. A questionnaire was used to assess pain and anesthesia/hypoesthesia. The most common objective and subjective signs that were correlated with the healing process were edema, hematoma, trismus, pain, and anesthesia/hypoesthesia. Edema peaked at 48–72 h postoperatively (distance between eye’s external canthus and gonion, mean difference = 4.53, between tragus and cheilion, mean difference = 7, between tragus and gnathion, mean difference = 4.65, p < 0.001); mouth opening amplitude was significantly decreased during the first two weeks postsurgery (class II, mean difference = 32.42, p = 0.006, class III, mean difference = 44.57, p < 0.001), but it steadily and considerably improved over three months. The nose tended to widen postsurgery. The most severe pain experienced by patients was of medium intensity in the mandibular body, described as pressure, and usually did not spread. Patients were most severely and persistently impacted by anesthesia/hypoesthesia.

“…(trismus), paresthesia, and so on [5]. To minimize symptoms and accelerate patient recovery, some pharmacological and nonpharmacological protocols have been extensively studied and used, such as cryotherapy, anti-inflammatory and analgesics, kinesiotaping, lymphatic drainage, vitamin complex supplementation, electroacupuncture, photobiomodulation (PBM) therapy, and so on [6][7][8][9][10][11][12].…”

“…In this context, PBM therapy using infrared lasers emerged as an easy-to-apply, low-cost, noninvasive, and low-complexity alternative for patient recovery [11][12][13][14]. The therapeutic effect of PBM is linked to increased cell activity and decreased edema, which is attributed to decreased vascular permeability, increased angiogenesis, and local lymphatic circulation [15].…”

This study aimed to evaluate the effectiveness of photobiomodulation (PBM) therapy using 940‐nm laser in patients undergoing orthognathic surgery. Twenty individuals were randomly distributed into laser (n = 10) and control (n = 10) groups. The PBM was conducted immediately after surgery, after 24 h, 48 h, and weekly for up to 4 weeks. All participants were evaluated for pain, edema, trismus and paresthesia. Data were compared by Fisher's and Mann–Whitney or chi‐square tests (5%). The pain decreased from 24 h to 4 weeks, with the laser group reaching any pain after 3 weeks (p < 0.001). A significant difference was noticed for trismus on days 14 and 30 (p = 0.002; p = 0.019), without difference in paresthesia (p = 0.198). Edema was lower on the laser group compared to control, without a significant difference for most measurements. Data indicate that 940‐nm PBM therapy decreased the occurrence of postoperative pain and significantly improved trismus.

The Efficacy of Low-Level Laser Therapy Combined with Single Flap Periodontal Surgery in the Management of Intrabony Periodontal Defects: A Randomized Controlled Trial

et al. 2022

View full text Add to dashboard Cite

This study aimed at assessing the clinical outcomes of the Single Flap Approach (SFA) with the additional use of Low-level laser therapy (LLLT). The defects were treated as per the principles of SFA, whereby 20 defects received only SFA (control group) and 20 defects received additional LLLT for bio stimulation/bio modulation (test group). Stable primary closure of the flaps was obtained with vertical internal mattress sutures. Plaque indices (FMPS), clinical attachment levels (CAL), probing pocket depth (PPD), and gingival bleeding scores (FMBS) were calculated at baseline, and at the 3rd and 6th months in both groups. An EHI score of 1 was observed at all sites except for two, where a score of 2 in the control group at week 2 was observed. In the test group, the PPD reduction at 6 months was 3.60 ± 0.95 and in the control group it was 3.75 ± 0.91 mm. CAL gain at 6 months was 2.70 ± 1.36 mm and 3.45 ± 1.2 mm in the test group and showed no statistical significance. These data suggested the positive effect of LLLT over CAL gain; thus, LLLT may be combined with SFA to potentially enhance the early wound healing and higher clinical outcomes in terms of increase in CAL and decrease in PPD.
