Radiologic Risk Factors for Persistent Mandibular Nerve Neurosensory Disturbance Following Sagittal Split Osteotomy

Neurosensory disturbance (NSD) occurring in the lower lips and chin is a major postoperative complication related to bilateral sagittal split osteotomy (SSO). The purpose of this study is to identify preoperative radiographic findings following SSO procedure associated with persistent NSD. This retrospective cohort study analyzed data for consecutive patients who underwent SSO. Primary predictor variables, including ramus width, mandibular body height, mandibular angle length, gonial angle, distance from mental foramen to distal aspect of mandibular second molar (MFD), and measurement of bone marrow space (BMS), were examined in a series of radiographic images. The primary outcome variable was NSD. Patients with NSD were divided into 2 groups based on findings obtained 1year postoperatively: persistent, for those with NSD remaining after 1year, and transient, when NSD occurred for less than 1year. Covariates included sex and age. Comparisons were analyzed by use of Mann-Whitney U test or χ2 test. Multivariate analysis was performed using step-wise logistic regression to determine significant factors related to persistent NSD. A P value .005 or less was considered statistically significant. Of the 349 sides investigated, the persistent NSD group consisted of 59 sides (16.9%), while the transient NSD group consisted of 290 sides (83.1%). The occurrence of persistent NSD was correlated with age (P<.05), MFD (P<.001), mandibular body height (P<.05), and BMS (P<.001). Multivariate logistic analysis also showed a significant association of MFD (P<.001) and BMS (P<.001). Preoperative MFD and BMS are radiographic findings that are associated with an increased risk for persistent NSD following SSO procedure.

Evaluation of Infraorbital Nerve Recovery and its Effect on Quality of Life following Open Reduction and Internal Fixation of Zygomaticomaxillary Complex Fractures - An Evaluative Study.

The zygomaticomaxillary complex (ZMC) fractures are the second most common fractures affecting the midfacial skeleton. Neurosensory disturbances of the infraorbital nerve are one of the most common signs of ZMC fractures. The aim of the study was to evaluate the neurosensory recovery of the infraorbital nerve and its effect on the quality of life (QoL) following open reduction and internal fixation of ZMC fractures. Thirteen patients clinically and radiologically diagnosed with unilateral ZMC fractures with neurosensory deficits of the infraorbital nerve were enrolled for this study. All patients were assessed presurgically for neurosensory deficits of the infraorbital nerve using the various neurosensory tests, followed by open reduction with two-point fixation under general anaesthesia. The patients were followed up at one, three and six months postoperatively to evaluate the recovery of neurosensory deficits. Recovery of tactile and pain sensation was relatively complete in 84.62% and 76.92% of patients respectively by the end of six months postoperatively. The spatial mechanoreception of the affected side improved significantly. 61.54% of patients led an excellent QoL six months postoperatively. The majority of the patients with ZMC fractures and neurosensory deficits of the infraorbital nerve, when treated with open reduction and internal fixation, have complete recovery of the neurosensory deficits by the end of six months postoperatively. However, some patients may continue to experience some long-term residual deficits, which can affect the patient's QoL.

RETROSPECTIVE ANALYSIS OF NEUROSENSORY DISTURBANCES RELATED TO DENTAL IMPLANT PLACEMENT IN MANDIBULAR INTERFORAMINAL REGION

The aim of this study is to evaluate the risk of neurosensory disturbances resulting from the injury of the anterior loop of the inferior alveolar nerve (IAN) in dental implant surgery with panoramic radiography. Panoramic radiographs of 1614 consecutive patients treated with dental implants were examined, and patients with implants located at a distance less than 5 mm to the mental foramen were recorded. Paresthesia, anesthesia, neuropathic pain was investigated retrospectively. In 405 patients, the implants were located in a distance less than 5 mm to the mental foramen. A range of 0.6 mm to 5 mm distance was detected between the mental foramen and these dental implants. No patient complained of bilateral paresthesia. In five (2.06%) of the 242 regions, it was found that patients had permanent unilateral paresthesia in their lower lips. In conclusion, panoramic radiography is not an entirely reliable imaging method for dental implant planning in the interforaminal region. Methods that are more sophisticated may be required to assess the risk of neurosensory disorder before treatment.

Piezoelectric versus conventional techniques for orthognathic surgery: Systematic review and meta-analysis

PurposeA systematic review and meta-analysis of the advantages and disadvantages of the piezo surgery comparing with conventional osteotomy in orthognathic surgery. MethodsWe conducted this systemic review in accordance with the preferred reporting items for systematic reviews and meta-analysis (PRISMA) statement. We searched for relevant studies in the PubMed/MEDLINE, Embase databases, Lilacs, Scopus and Science Direct to identify prospective and retrospective studies, compare patient outcomes (intraoperative blood loss, operative time, neurosensory disturbance) after performing orthognathic surgery by conventional saw or piezo-electric device. According to pool individual results we used the mean difference (MD) with the 95% confidence interval (95% CI). ResultsAmong three studies that used conventional saw and three studies used piezo-electric device and nine studies used both techniques, the operative time required to perform orthognathic standard procedures was longer using piezo-electric device compared to conventional saw. The results showed that during using the conventional saw to perform orthognathic surgery the amount of the blood loss was higher than the amount while using piezo-electric device (MD -140.4 mL; P = 0.29). based on the studies that evaluated neurosensory disturbance, after 3 months and 6 months respectively, neurosensory disturbance was seen in 23.8% and 23.4% of patient who underwent conventional osteotomy versus 4.3% and 2.4% of the patients who underwent surgery in which piezo surgery was used. Our meta-analysis showed difference in neurosensory disturbance between piezo-surgery and conventional surgery at 3 months (MD -19.5; P = 0.11) and 6 months (MD -21; P = 0.5) postoperatively. ConclusionPiezo-electric device enabled lower blood loss and higher nerve integrity rates in outcomes according to the complications that associated with orthognathic surgery.

Complications related to orthognathic surgery: A 10-year experience in oral and maxillofacial training center

This article aimed to review adverse events and complications to orthognathic surgery based upon 10 years.This study was a retrospective investigation between 2009 and 2018. Independent variables such as sex, age, pre-operative conditions, diagnosis, type of surgery, bleeding volume, surgery duration, and hospitalization were recorded. The data regarding orthognathic surgery adverse events and complications were evaluated and statistically analyzed with a significance level of p < 0.05.A total of 891 patients were included in this study (male 39.1%, female 60.9%) with a mean age of 26.4 ± 6.09 years. A neurosensory disturbance was found as immediate post-operative sequelae as 93.5%. The four most frequent complications had a relapse (6.4%), post-operative TMD (5.7%), unfavorable osteotomy (5.5%), and infection (4.9%), which seem to be more common in males. An average blood loss was 497 ± 371 ml and the average operative time was 401 ± 109.3 min. Complication rates were statistically affected by bleeding volume (p-value = 0.01), operative time (p-value = 0.03), and type of skeletal deformity (p-value = 0.01).Although numerous complications were recorded, no fatal complications were experienced. Bleeding time, operative time, and skeletal classification have significant influence on orthognathic surgery complications. However, a multitude of factors could be modified to reduce the complication rate and improve the result of the treatment. One of the most significant factors was the operative time.

Postoperative Complications in Genioplasty and Their Association with Age, Gender, and Type of Genioplasty.

Objective The objective of our study was to determine the incidence of postoperative complications associated with different kinds of genioplasties done with or without concomitant orthognathic surgeries. Materials and Methods Patients in whom facial asymmetry was corrected by genioplasty with age ranging from 16 to 55 at the Department of Oral and Maxillofacial Surgery were included in the study. Patients with facial asymmetry due to congenital problems were excluded. Results 59 patients were included, of which 38 were males and 21 were females with the age range of 16–55 (mean: 27.3729, Std. deviation: 4.70472). Advancement genioplasty was performed in 15.3%, reduction genioplasty was done in 16.9%, and advancement genioplasty with rotation was performed in 67.8% cases. In 28.8% cases, genioplasty was performed as an adjunct procedure with orthognathic surgery, and in 71.2% cases, genioplasty was performed alone. 3.4% patients developed infection, 8.5% had hematoma, and 6.8% had temporary numbness. Postoperative complications were seen more in men than in women. Correction of chin asymmetry by rotation/advancement showed the highest number of complications (84%). Conclusion Temporary neurosensory disturbance of the inferior alveolar nerve is the most common complication that occurs after genioplasty. Patients shall be counselled preoperatively, and informed consent shall be obtained prior to surgery.

ASSESSMENT OF NEUROSENSORY DISTURBANCES AND RECOVERY FOLLOWING SURGICAL REMOVAL OF IMPACTED MANDIBULAR THIRD MOLAR – A PROSPECTIVE STUDY

Aim: This prospective study aim to determine the incidence and pattern of recovery of IAN and LN decits after surgery while comparing which nerve, site, side, age group and type of impaction was most likely to suffer from neurosensory disturbances and to evaluate the risk factors such as duration of surgery, proximity to inferior alveolar canal, excessive hemorrhage, clinical observation of neurovascular bundle, contributing to these postoperative neurosensory decits. Materials&amp;Methods: This study was conducted on 30 patients who underwent surgical removal of impacted mandibular third molar between 2017-2019 in the Department of Oral and Maxillofacial Surgery, College of Dental Sciences, Davangere. Clinically, all the patients underwent objective evaluation by using pin prick test, two-point discrimination and blunt test. Sensory function was evaluated 1 week, 1, 3 and 6 months post-operatively. The areas that were evaluated are those supplied by IAN and LN. Result: The incidence of NSD in our study was 10%, the IAN 6.7% and LN decit 3.3%. No permanent NSD was observed in this study. Statistically signicant association was found between excessive hemorrhage from the socket and NSD (p=0.009). No signicant association was found between gender, age, side, type, difculty score and duration, observation of neurovascular bundle during surgery and proximity of roots to the inferior alveolar canal with NSD.

A Comprehensive Examination of Severely Ill ME/CFS Patients.

One in four myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) patients are estimated to be severely affected by the disease, and these house-bound or bedbound patients are currently understudied. Here, we report a comprehensive examination of the symptoms and clinical laboratory tests of a cohort of severely ill patients and healthy controls. The greatly reduced quality of life of the patients was negatively correlated with clinical depression. The most troublesome symptoms included fatigue (85%), pain (65%), cognitive impairment (50%), orthostatic intolerance (45%), sleep disturbance (35%), post-exertional malaise (30%), and neurosensory disturbance (30%). Sleep profiles and cognitive tests revealed distinctive impairments. Lower morning cortisol level and alterations in its diurnal rhythm were observed in the patients, and antibody and antigen measurements showed no evidence for acute infections by common viral or bacterial pathogens. These results highlight the urgent need of developing molecular diagnostic tests for ME/CFS. In addition, there was a striking similarity in symptoms between long COVID and ME/CFS, suggesting that studies on the mechanism and treatment of ME/CFS may help prevent and treat long COVID and vice versa.

Zygomaticomaxillary complex (ZMC) fractures are relatively common. Zygomatic complex fractures with functional or aesthetic impairments often require surgical intervention. Treatment of ZMC fractures consists of reduction and fixation of the dislocated bone fragments to their original location. The zygomaticomaxillary complex functions as a major buttress for the face and because of its prominent convex shape, is frequently involved in facial trauma.1 ZMC fractures are also called tripod, tetrapod, quadripod, malar or trimalar fractures. They account for approximately 15 % - 23.5 % of maxillofacial fractures.2,3 The aetiology of zygomatic complex fractures primarily includes road traffic accidents (RTA), violent assaults, falls and sports injuries. They are the second most common facial fracture after nasal bone fractures.3-6 ZMC fractures are more common in men than women, and most commonly occur in the third decade of life.7-10 The main clinical features of zygomatic complex fractures include diplopia, enophthalmos, subconjunctival ecchymosis, extraocular muscle entrapment, cosmetic deformity, malocclusion and neurosensory disturbances of the infra-orbital nerve.10 The gold standard radiological investigation for evaluation of ZMC fractures is computed tomography (CT) scan. Surgical intervention is effective in cases of displaced and comminuted fractures involving functional and aesthetic defects, whereas a nonsurgical approach is often used for non-displaced fractures.11 Various surgical approaches and treatment strategies have been proposed to obtain a successful treatment outcome. Based on review of literature, it has been observed that the open reduction with internal fixation using mini plates and screws is the most commonly preferred treatment for displaced and comminuted fractures.10-12 Here, we report a clinical case of right zygomaticomaxillary complex fracture and its management.

Management of Traumatic Trigeminal and Facial Nerve Injuries.

In the area of craniomaxillofacial trauma, neurosensory disturbances are encountered commonly, especially with regard to the trigeminal and facial nerve systems. This article reviews the specific microanatomy of both cranial nerves V and VII, and evaluates contemporary neurosensory testing, current imaging modalities, and available nerve injury classification systems. In addition, the article proposes treatment paradigms for management of trigeminal and facial nerve injuries, specifically with regard to the craniomaxillofacial trauma setting.

Does the use of a piezoelectric saw improve neurosensory recovery following sagittal split osteotomy?

Neurosensory disturbance of the inferior alveolar nerve (IAN) is an adverse effect associated with sagittal split osteotomies (SSO). The purpose of this work was to evaluate neurosensory recovery of the IAN when SSOs were performed with piezoelectric (PZ) versus reciprocating (RP) saws. This was a prospective split-mouth study of patients undergoing bilateral SSO using a PZ saw on one side and an RP saw on the other. The primary outcome of interest was neurosensory recovery, as assessed using the functional sensory recovery (FSR) scale defined by the UK Medical Research Council. Descriptive, bivariate, and regression statistics were computed. Twenty patients (40 SSOs) with a mean age of 19.9 ± 3.2 years were included. The mean mandibular movement did not differ significantly (P = 0.50) between the PZ and RP groups. All patients achieved FSR within 1 year of surgery (range 34–249 days). The median time to FSR overall was comparable between the PZ and RP groups (94.5 days and 101.5 days, respectively; P = 0.20). However, at the time FSR was achieved, PZ SSO sites were more likely to have higher neurosensory scores when compared to RP SSO sites (hazard ratio 2.3, 95% confidence interval 1.1–4.9, P = 0.04).

Do anatomical variations of the mandibular canal pose an increased risk of inferior alveolar nerve injury after third molar removal?

The present study aimed to assess whether anatomical variations of the mandibular canal are associated with neurosensory disturbances of the inferior alveolar nerve (IAN) following mandibular third molar removal. Two observers compared the detection of third molar root-nerve relations and bifurcations of the mandibular canal on panoramic radiographs and CBCT images of 201 patients undergoing removal of 357 mandibular third molars. Potential neurosensory disturbances of the IAN were surveyed ten days after surgery. Fisher's Exact was performed to correlate presence of canal variations to postoperative neurosensory disturbances. Positive and negative predictive values (PPV, NPV) and likelihood ratios (LR + , LR-) were calculated. Thirteen patients reported postoperative altered sensation of the lower lip, with 2 of them having mandibular canal bifurcations on the ipsilateral side of the injury. Fisher's Exact showed that the studied mandibular canal variations were not related to postoperative neurosensory disturbances. CBCT was superior in visualization of anatomical variations of the mandibular canal. Prevalence of bifurcations was 14% on CBCT and 7% on panoramic radiographs. In both imaging modalities and for all parameters, PPVs were low (0.04 - 0.06) and NPVs were high (0.92 - 0.98), with LR ranging around 1. In the present study, the assessed mandibular canal variations had limited predictive value for IAN neurosensory disturbances following third molar removal. While a close relation between the third molar and the mandibular canal remains a high risk factor, mandibular canal variations did not pose an increased risk of postoperative IAN injury after third molar removal.

Diagnostic accuracy of CBCT compared to panoramic radiography in predicting IAN exposure: a systematic review and meta-analysis.

The aim of this study is to verify whether the diagnostic accuracy of cone beam computed tomography (CBCT) is superior to panoramic radiography (PR) in predicting inferior alveolar nerve (IAN) exposure during the lower third molar extraction. Eight electronic databases were searched up to September 2020. Studies that evaluated the accuracy (sensitivity, specificity, positive-predictive value, and negative predictive value) of both imaging methods were included. The gold standard was the visualization of the IAN exposure during the extraction of lower third molars. The gray literature was also used to include any other paper that might meet the eligibility criteria. The meta-analysis was performed with OpenMeta-Analyst and ReviewManager v.5.3 software. The methodology of the studies was evaluated using QUADAS-2. Among the search, three studies met all the eligibility criteria and were included in the qualitative and quantitative synthesis. The meta-analysis was conducted with all included studies. Accuracy values for CBCT were 95.1% for sensitivity (p=0.666) and 64.4% for specificity (p<0.001). For PR sensitivity and specificity, we observed 73.9% (p=0.101) and 24.8% (p<0.001), respectively. Both exams were reliable for detecting positive cases of exposure of the IAN. However, CBCT had a better performance compared to PT in predicting IAN exposure during surgery. To better understand the CBCT accuracy in predicting the IAN exposure during surgery, since this event can increase the likelihood of IAN injury and, consequently, cause neurosensory disturbances.

Prognostic factors, symptom evolution, and quality of life of posttraumatic trigeminal neuropathy.

Neurosensory disturbances (NSDs) caused by injury to the trigeminal nerve can affect many aspects of daily life. However, factors affecting the persistence of NSDs in patients with posttraumatic trigeminal neuropathies (PTTNs) remain largely unknown. The identification of such risk factors will allow for the phenotyping of patients with PTTNs, which is crucial for improving treatment strategies. We therefore aimed to identify the prognostic factors of NSD persistence, pain intensity, and quality of life (QoL) in patients with PTTNs and to use these factors to create a prognostic prediction model. We first performed a bivariate analysis using retrospective longitudinal data from 384 patients with NSDs related to posttraumatic injury of the trigeminal nerve (mean follow-up time: 322 ± 302 weeks). Bivariate and multivariate analyses were performed. The multivariable prediction model to predict persistent NSDs was able to identify 76.9% of patients with persistent NSDs, with an excellent level of discrimination (area under the receiver operating characteristic curve: 0.84; sensitivity: 81.8%; specificity: 70.0%). Furthermore, neurosensory recovery was significantly associated with sex; injury caused by local anesthesia, extraction, third molar surgery, or endodontic treatment; and the presence of thermal hyperesthesia. Pain intensity and QoL analysis revealed several factors associated with higher pain levels and poorer QoL. Together, our findings may aid in predicting patient prognosis after dental, oral, and maxillofacial surgery and might lead to personalized treatment options and improved patient outcomes.

A New Concept of Safety Distance to Place Implants in the Area of the Inferior Alveolar Canal to Avoid Neurosensory Disturbance.

Inferior alveolar nerve (IAN) damage following implant placement is a severe complication that can compromise a patient's quality of life. Previous studies have suggested that a safety zone of 2 mm, if maintained, might avoid this problem. This retrospective study evaluates implants placed in closer proximity to the IAN without resulting in any postoperative neurologic complications and suggests a new concept of safety distance. A total of 60 consecutive patients receiving 101 mandibular implants < 2 mm from the IAN were included in this study. All enrolled patients had a CBCT scan done for radiologic assessment before implant placement and following final restoration. Measurements were obtained through cross-sectional views using Simplant software. In patients without neurologic disturbances, a mean distance of +0.75 mm was seen from the closest portion of the implant to the nerve bundle. In cases where a direct transection and/or compression of the nerve was not observed, the patients did not experience neurosensory disturbances.

ACTINOMYCES-ASSOCIATED CALCIFICATIONS IN A MANDIBULAR DENTIGEROUS CYST THAT PRESENTED WITH INFERIOR ALVEOLAR NERVE PARESTHESIA

<h3>Introduction</h3> Dentigerous cysts account for approximately 20% of all odontogenic cysts. The classical presentation is as a unilocular radiolucent lesion associated with an unerupted tooth. Typically asymptomatic, they are often an incidental finding of radiographic investigations. The objective of this case report is to highlight that infected dentigerous cysts may have an atypical presentation that may raise the clinical suspicion of a neoplastic process. <h3>Case Description</h3> This case report describes a rare and atypical presentation of a dentigerous cyst in the mandible that presented with pain and paresthesia of the lower lip. The radiological presentation of the lesion was also unusual, with the lesion manifesting as a well-defined radiolucency containing multiple radiopacities. Histology revealed an infected dentigerous cyst with <i>Actinomyces</i> colonies and dystrophic calcification. <h3>Discussion</h3> There are very few described cases of dentigerous cysts presenting with paresthesia and/or <i>Actinomyces</i>-associated calcification. Our literature review, however, suggests that <i>Actinomyces</i>-associated pathology is more common than one would expect. Although actinomycosis is typically described as an infection of soft tissues, <i>Actinomyces</i>-associated lesions can have a highly variable clinical presentation. This includes the ability to produce <i>Actinomyces</i>-associated calcifications, although this is rarely observed. <h3>Conclusions</h3> Infected dentigerous cysts containing <i>Actinomyces-</i>associated calcifications may need to be considered in the differential diagnosis of lesions presenting as a mixed radiopacity in the jaws. This case also draws attention to the fact that neurosensory disturbance, which is typically associated with malignant disease and injury to the neurovascular bundle, can be a presenting feature of benign entities such as dentigerous cysts.

Dental implant placement with inferior alveolar nerve repositioning in severely resorbed mandibles: a retrospective multicenter study of implant success and survival rates, and lower lip sensory disturbances

BackgroundThe purpose of this study was to analyze medium-to-long-term implant success and survival rates, and lower lip sensory disturbance after placement of dental implants with simultaneous inferior alveolar nerve (IAN) repositioning.MethodsFifteen patients (3 men, 12 women) treated in two centers were included in this retrospective study. The ages of the participants ranged from 19 to 68. A total of 48 dental implants were placed in 23 posterior mandibular segments simultaneously with IAN transposition or lateralization. The residual bone above the IAN ranged from 0.5 to 7.0 mm. Crestal bone changes were measured using cone beam computed tomography (CBCT) images. Disturbance of the IAN was evaluated subjectively using a modified questionnaire.ResultsThe healing process was uneventful in fourteen patients. In one patient, spontaneous fracture of the operated mandible occurred on tenth day after the surgery. The implant in the fracture line was removed at the time of open reduction and fixation. One more implant was lost after 5 years of loading. Therefore, the overall dental implant survival rate was 95.8%, whereas all implants in function were judged as successful after a follow-up period of 1 to 10 years. Transient neurosensory disturbances (ND) were observed in all patients who underwent IAN lateralization and IAN transposition. At follow-up times of 3 years, 5 years, and 10 years, weak hypoesthesia remained in two subjects treated with IAN transposition. None of the patients developed neuropathic pain after the procedure.ConclusionsWithin the limitations of this study, we conclude that reconstruction of severely resorbed mandibles with dental implants in conjunction with IAN repositioning is an effective and reliable technique. Although neurosensory disturbances are the most common complication after surgery, they tend to resolve over time. Advanced surgical skills are required to perform this technique.

Evaluation of Sagittal Curving Osteotomy vs Conventional Advancement Genioplasty in Retrogenia Patients: a Randomized Control Trial.

With increasing aesthetic awareness, in addition to the forehead, nose, and cheekbone prominence, the chin nowadays is seen as one of the most important parts of the facial skeleton. Position of the chin has a strong influence on the assessment of the facial harmony; its different types and forms dominate the appearance. Furthermore, the expression of the chin is equated with character traits, and thus, it is an important component of the profile forms. Genioplasty is a routine procedure for the correction of aesthetic and functional deformity of the chin region. It is therefore one of the contour-enhancing surgical methods. The purpose of the present study is to study the versatility of sagittal curving osteotomy for advancement genioplasty as an alternative to conventional technique. A total of 24 subjects were enrolled for the study who were randomly distributed into two groups: group 1(n-12) comprising of patients in whom sagittal curving osteotomy was done and group 2 (n- 12) comprising of patients in whom conventional osteotomy was done. Neurosensory disturbances and hard and soft tissue relapse were compared between the two groups. On comparison of all the variables, it was found that the conventional osteotomy technique had more hard tissue relapse and more neurosensory disturbance as compared to sagittal curving osteotomy technique. Results of this study suggest that the use of sagittal curving osteotomy may be helpful in reducing postoperative neurosensory disturbances and relapses following genioplasty. Hence, it is recommended that sagittal curving osteotomy can be used as an alternative osteotomy technique for advancement genioplasty.

Complications of distraction osteogenesis: Narrative review

AbstractAimThe aim of this narrative review is to discuss the complications of distraction osteogenesis (DO) of facial skeleton and their management.Materials and MethodA detailed literature search was done on PubMed, Google Scholar and Embase from the year 1990 onwards. Any systematic review, randomized controlled trial, controlled clinical trial, retrospective/prospective study discussing about complications of maxillofacial DO and their management were included.ResultsComplications related to DO were divided based on phases as (a) planning (patient counselling, improper vector, errors in device selection, etc.), (b) surgery (tooth injury, neurosensory disturbance, incomplete osteotomy, etc.), (c) distraction (device failure, pain at regenerate site, premature consolidation, etc.) and (d) consolidation (infection, hypertrophic scar, relapse, etc.).ConclusionWidespread applications are possible with DO though it is a device‐dependent and technique‐sensitive procedure. With proper planning and execution, DO can become the gold standard for managing various maxillofacial disorders.
