Comparison of Wrinkle Patterns Generated by Intradermal and Intramuscular Botulinum Toxin Injections by Clinical Evaluation.

Purpose: Botulinum toxin has played a remarkable role in management of forehead wrinkles. Most used is intramuscular technique due to its deposition into the muscles, however, with adverse effects like brow ptosis. This study has been designed for the evaluation of efficacy for intradermal v/s intramuscular route of botulinum toxin injections for forehead wrinkles using clinical correlation. Methods: This study included a clinical trial of 32 facial halves divided equally into intradermal and intramuscular injection technique groups, receiving total dose of 8 U. Results were assessed by clinical examination upto 2 weeks and 4 weeks with parameters; objective wrinkle rate, eyebrow height, eyebrow movement, pain, and satisfaction after treatment. Result: Results showed least mean for objective wrinkle rate in intramuscular group, showing statistically significant improvement. Overall improvement in eyebrow height and eyebrow movement were slightly more for intramuscular group. Pain was lesser for intradermal group, whereas satisfaction of patient of patient post treatment is similar for both the groups. Conclusion: Among intradermal and intramuscular botulinum toxin injection technique, the effect and potency were better for intramuscular technique, whereas the patient comfort and compliance were better for intradermal technique.

Parallel osteotome technique: new approach to reduce neurosensory disturbances following bilateral sagittal split osteotomy.

PURPOSE: To determine clinically if parallel osteotome technique (POST) reduces incidence of neurosensory disturbances (NSD) following bilateral sagittal split osteotomy (BSSO), and to corroborate the findings with finite element analysis (FEA). PATIENTS METHODS: The investigation was a quasi-experimental study involving 30 patients requiring BSSO. The sample was divided into two groups: control undergoing conventional osteotomy technique and experimental using POST. An FEA simulation of the two advocated techniques were also generated for computational analysis. Primary outcome was clinical comparison of subjective and objective measures for NSD, while secondary outcome was comparison of stress, strain and deformation. Osteotomy technique was the exposure studied. Data was analyzed for differences in proportions and means. RESULTS: Thirty patients (12 females and 18 males) with an age range of 18 to 28 (mean 21.6) years were recruited for the study. This provided 60 sides as sample for the study. The experimental group demonstrated significantly lower subjective scores for NSD for the 3 rd (p=0.03) and 6 th month reviews (p=0.025). Objective testing revealed lower incidence of NSD for the experimental group during the 3 rd (p=0.07), 6 th (p=0.007) and 12 th post-operative months (p=0.17). The computational analysis also revealed significantly lower stress (p=0.007), strain (p=0.009) and deformation (p=0.04) on the inferior alveolar nerve with the POST method. CONCLUSION: Incidence of NSD following BSSO is lower with POST. The technique also induces significantly lower deformational forces on the IAN when compared with the conventional osteotomy method.

Trans-mastoid anchorage as a novelty in glenoid fossa reconstruction for hemifacial microsomia with agenesis of zygomatic arch and external acoustic meatus-Technical note with a case illustration.

Total joint reconstruction (TJR) has become the most preferred method of reconstruction in recent years for hemifacial microsomia (HFM). This requires meticulous planning for the glenoid fossa and ramus prosthesis along with the arch in certain indications. TJR in a type V HFM is extremely challenging due to agenesis/hypolasia of the zygoma and arch which compromises anchorage of the glenoid prosthesis. Conventional options used for such indications incorporate extended designs for the fossa. However, the two designs used commonly are associated with limitations; (i) the temporal extension is overtly large and cannot be anchored in patients with thin temporal bone and (ii) the glenoid fossa incorporated into the arch prosthesis, where the fossa is not positioned on stable bone and occlusal loading is non-physiological; transmitted onto the arch prosthesis rather than the skull base. The authors propose the use of the mastoid process as an alternative for anchorage of fossa prosthesis. This technique offers stable anchorage while facilitating ideal positioning on the skull base for optimal masticatory load transmission. The case illustration depicts reconstruction of the TMJ, zygoma and the zygomatic arch in a 31-year-old man with type V HFM, with a three-year follow-up, with good clinical outcomes sans complications.

Management of Lingual Cortex Fracture of Mandible Using Lingual Arch Bar: A Finite Element Analysis of Reduction with a Pilot Clinical Trial.

Purpose: Fractures of lingual cortex are frequently left untreated leading to poor resolution of patient's symptoms and function. Positioning an implant on same side of fracture would provide better reduction. The study aims at improving stability offered by Erich arch bar placed on lingual surface, by Finite element analysis (FEA) along with a pilot clinical trial. Methods: Two FEA models were generated from CT scan of an individual having lingual cortex fracture: control model with labial arch bar and study model with lingual arch bar. Parameters assessed: Stress distribution (Mpa) along lines of osteosynthesis; Separation of fracture fragments (mm) across fracture line. Associated, was a clinical trial of 5 patients, managed by placing lingual arch bar. Feasibility of arch bar, post-operative pain, radiographic inter-fragmentary gap and complications were assessed clinically. Results: Lingual positioning of arch bar demonstrated less displacement (mm) of fracture fragments compared to labial placement (0.123 vs. 0.677) upon application of masticatory load. Insignificant lingual splay and lesser degree of stress distribution (Mpa) was observed (83.1 vs. 99.3) favoring placement of arch bar on lingual side. Clinical trial correlated with outcomes of FEA, resulting in improvement of patient's symptoms. Conclusion: FEA and supporting clinical trial provided an effective method of reduction for lingual cortical fracture.

An Overview of Systematic Reviews on the Surgical Management of Obstructive Sleep Apnoea.

Background: Obstructive Sleep Apnoea (OSA) is a common sleep disorder marked by partial or total obstruction of the upper airway while a person is asleep leading to breathing difficulty, reduced oxygenation and frequent awakenings. This condition affects the general health significantly compromising quality of life. The objective of this overview  is to thoroughly assess the systematic reviews on current surgical therapies for the management of OSA in terms of patient outcomes. Methods: A thorough literature search was performed from inception till 31st December 2022 using PubMed, and Cochrane databases. Studies evaluating the effectiveness and safety of different surgical techniques for the management of OSA were considered. The quality of articles was assessed using AMSTAR (A MeaSurement Tool to Assess systematic Reviews) and Glenny et al. checklist. Results: Out of eighteen studies, only seven studies met the inclusion and exclusion criteria. Results showed that the majority of studies were in the pediatric age group except one systematic  review which assessed the adult age group. Conclusion: None of the published articles had compared all surgical procedures based on the standard evaluating procedure nor followed all reporting guidelines in the primary studies. For better implementation, further multi center studies are warranted with unique reporting criteria and guidelines about pre- as well as post-operative phases. Future research should concentrate on contrasting strategies, combination therapies, and evaluating long-term effects.

Evaluation of sub-brow approach to the frontozygomatic suture for Open Reduction and Internal Fixation (ORIF) of Zygomatico maxillary complex (ZMC) fractures: A prospective cohort study.

Introduction: Contemporary incisions used to access the frontozygomatic (FZ) sutures are the lateral brow and upper blepharoplasty incisions which are associated with specific limitations and complications. The authors describe the use of sub-brow incision as an alternate approach for exposure of the FZ region. Methods: This is a prospective cohort study involving patients requiring surgical management of zygomatico maxillary complex (ZMC) fractures with fixation at FZ suture alone or along with fixation at infra-orbital rim and/or zygomaticomaxillary buttress. A sub-brow incision was used to expose the fracture and fixation was done with a 4-hole miniplate. The parameters evaluated were specific to the FZ region (sub-brow incision), namely surgical access, bleeding, fracture exposure time, post-operative scar, and pain. Each patient was reviewed on 1st, 5th, 7th, 10th, 30th, and 90th day. Results: The study sample included eight male patients. The mean age was 30 years. The sub-brow incision demonstrated favorable postoperative outcomes; adequate exposure was achieved in all 8 patients. The scar formation was found to be higher on the 7th day and the least scar formation was seen by the third month. The mean pain score was found to be high on first post-operative day and the least pain was seen by the 10th day. The mean score of surgical field bleeding was found to be 1.75 which signified mild bleeding according to Fromme's scale. The mean time taken for adequate exposure of the fracture was 6.62 min. All the assessment parameters were statistically significant (P value <0.01). Conclusion: Sub-brow incision is an effective approach for ORIF of zygomatic fractures at FZ suture. The technique is quick, simple, and associated with minimal complications.

"Trans-zygomatic approach" for reduction & internal fixation of a malunited, medially dislocated condyle fracture in a geriatric patient with cervical spine injury.

The open reduction and internal fixation of medially displaced/dislocated condyle fracture is challenging due to inadequate visibility and access to the dislocated condyle. The common approach to reduction of such condyles is by inferior distraction of the mandible which facilitates visualization as well as instrumentation. However, this maneuver may be difficult, or contraindicated in patients with concomitant cervical spine injury where excessive manipulation of the mandible may predispose the spine to further trauma. Ramus osteotomies which are used when conventional reduction methods fail, facilitate reduction but are associated with additional incision, complications and surgical time. This case report presents an alternative method, the "trans-zygomatic approach" which was used effectively to reduce a dislocated and malunited condyle fracture in a geriatric patient with co-existent cervical spine injury. The approach facilitated precise reduction of condyle fracture with minimal impact on the cervical spine.

Genioplasty in Contemporary Orthognathic Surgery.

In contemporary orthognathic surgery planning, the genium/chin constitutes an important part that contributes to the maxillofacial profile. The aesthetics of the lower face is affected by the position of the genium which makes reestablishment of genial morphology an essential component. It is hence necessary to evaluate the genium objectively on its individual merit, and any discrepancy is addressed accordingly. This review presents an overview of contemporary genioplasty techniques, their applications, and considerations on stability, osteosynthesis, complications, and the future developments.

External auditory canal injuries in maxillofacial trauma - Proposal of a symptom-based treatment algorithm with a report of twelve cases.

Purpose: Injury to the external auditory canal (EAC) may occur following facial trauma. They manifest as otalgia, ear bleeding, otorrhea, facial palsy, or altered hearing. But literature regarding its management is sparse. The study aimed to identify the incidence and types of EAC injury in facial trauma, grade their severity, and propose a symptom-based treatment algorithm. Patients and Methods: This was a prospective case series involving patients with signs/symptoms of EAC injury following maxillofacial trauma. The EAC was evaluated by clinical examination, imaging, endoscopy, and audiometry. Clinical findings were graded into mild, moderate, and severe. Treatment was matched to clinical findings according to the proposed algorithm. The outcomes of the study were incidence and types of EAC injury in facial trauma and resolution of presenting signs/symptoms. Data were analyzed for descriptive statistics using SPSS software (v26; IBM, Armonk, NY). Results: A total of 88 patients reported with maxillofacial trauma during a 6-month period. Signs/symptoms of EAC injury were observed in 41 patients, of which 12 (11 males and 1 female) were confirmed with a diagnosis of EAC injuries. Eight patients demonstrated only cartilaginous injuries while three had bony injuries. Treatment was successful in 11 out of 12 patients, with a best point estimate of 0.86 (Z score-1.959, 95% CI). Conclusion: Clinical findings of EAC injury mandate thorough investigation to ascertain the site and severity of the injury. Symptom-based treatment of EAC injuries produces an effective resolution of signs/symptoms and improved treatment outcomes.

Effect of platelet-rich fibrin on extraction socket healing in diabetic patients - A split-mouth crossover study: A prospective clinical trial.

Aims: The aim of this study is to evaluate the effectiveness of platelet-rich fibrin (PRF) in postextraction socket healing in diabetic patients. Subjects and Methods: The investigators implemented a randomized, split-mouth study in 100 Type 2 diabetic patients undergoing dental extraction of two or more teeth. Following extraction, the experimental socket was packed with PRF and sutured, while the control socket was sutured without packing. The primary outcome measures were soft-tissue healing (assessed by color, bleeding on palpation, granulation tissue, and incidence of suppuration and dry socket), hard-tissue healing (measured by visual interpretation, area of bone coverage, and grayscale analysis), and visual pain scores. Statistical Analysis: Statistical analysis was done using the independent and paired t-tests, analysis of variance, and Chi-square test. Results: Both soft-tissue healing and hard-tissue healing were significantly better in the experimental socket as compared to the control socket. Pain levels, as measured by the visual analog score, were similar in both the extraction sockets. Conclusions: The use of PRF has beneficial effects in extraction socket healing in diabetic patients.

Prospective cohort study on short-term evaluation of septoplasty as early management of naso-septal fractures - A correlation of clinical outcomes with computational fluid dynamic parameters.

PURPOSE: Post-traumatic deviated nasal septum (PTDNS) leads to impaired breathing and poor esthetics. The aim of this study was to assess treatment outcomes of early septoplasty for correction of PTDNS and correlate it with computational fluid dynamic (CFD) parameters. METHODS: This prospective cohort study included patients who underwent early septoplasty for PTDNS. Outcome variables were clinical (pain, nasal symmetry, and nasal obstruction) and computational (velocity, pressure, wall shear stress and Reynold's number). The cohort consisted of two groups: patients with history of closed reduction for nasal fractures (CR) and patients without (NCR). The primary outcome measure was response to treatment. Correlation between clinical and computational parameters, and influence of closed reduction on septoplasty outcomes were the secondary and tertiary outcomes, respectively. Descriptive and inferential statistics were performed to analyze data. Level of significance was fixed at 5% (α = 0.05). RESULTS: The sample included 12 patients, of which 5 underwent CFD analysis. Pain score reduced from a pre-operative mean of 7.3 to 0.5 post-operatively (p<0.001). All patients demonstrated reduction of nasal obstruction (p<0.001) and deviation (p<0.001) post-operatively. CFD analysis revealed post-operative reduction of velocity (p = 0.005) and Reynold's number (p = 0.007), with positive correlation between nasal obstruction and CFD parameters. Though patients in the CR group demonstrated reduced nasal deviation and obstruction before septoplasty, as compared to the NCR group, their outcomes were comparable following septoplasty. CONCLUSION: Early septoplasty improves functional and esthetic outcomes in patients with PTDNS. CFD simulation is a predictable method to objectively evaluate nasal function.

Ramal bone graft for management of infra-orbital rim fractures with defects - Technical note and a series of 16 cases.

The purpose is to describe a technique of using ramal bone graft for reconstructing defects of the infra-orbital rim (IOR), assess outcomes and complications. This was a retrospective chart review of 16 patients who underwent ramal bone grafting for IOR fractures. Outcomes evaluated were improvement in clinical findings (lid/globe malposition, tethering of facial skin and implant extrusion) and complications. Data analysis included descriptive statistics. The sample included 15 males and 1 female, with a mean age of 31.6 years. Lid malposition, globe malposition and tethering of facial skin was seen in 16, 13 and 6 patients, respectively. One patient demonstrated extrusion of implant. The mean size of bone harvested was 14 × 7 mm. All patients demonstrated improved globe position post-treatment, while 3 had residual lid retraction. Two patients demonstrated wound dehiscence in the donor site. In conclusion ramal bone graft was found to be a viable alternative for IOR reconstruction.

Does Intraoperative Navigation Improve Implant Position Accuracy in Orbital Fracture Repair?

Purpose: Our aim was to determine if intraoperative navigation (ION) improved radiographic outcomes in patients undergoing delayed primary/secondary orbital reconstruction for inferomedial defects, as measured by volume restoration, enophthalmos correction, and positional accuracy of implants. Patients and Methods: A prospective quasiexperimental study was performed to compare two groups of patients requiring orbital reconstruction. Use of ION was the exposure evaluated. Outcome measures were (i) intraorbital volume and enophthalmos evaluated radiologically, (ii) implant position accuracy, and (iii) procedural duration. Data were analyzed statistically to compare variance between groups. Results: Forty patients (6 females and 34 males) were recruited into the study with a mean age of 27.3 years. The study group demonstrated a greater reduction of intraorbital volume (0.49 cu.cm; p = 0.02) and enophthalmos (0.72 mm; p = 0.001). Implant positioning was more accurate using ION, with less mediolateral (p = 0.006) and yaw (p = 0.04) deviations. Surgical time for implant positioning was shorter by 17 min, with navigation (p < 0.001). Conclusion: The use of ION demonstrated radiographic improvements in volume restoration, enophthalmos correction, as well as accuracy of implant positioning, in patients requiring delayed primary/secondary orbital reconstruction.

Classification and Management of Infra-orbital Rim Fractures.

PURPOSE: Fractures of the infraorbital rim (IOR) are often undertreated with a resultant compromise of facial esthetics and function. The purpose of this research was to identify types of IOR fractures related clinical findings and assess post-treatment outcomes. METHODS: A retrospective cohort study was implemented involving all patients treated for IOR fractures during an 18-month period. Data consisted of treatment records, pretreatment and post-treatment photographs, and computed tomographic (CT) scans. The types of fractures were matched to the treatment instituted. The type of fracture was the independent variable, while the dependent variables were (i) clinical findings such as lid and globe malposition, tethering of facial skin, diplopia, and infraorbital nerve paresthesia, and (ii) treatment outcome assessed by surgeon and patient. Data were analyzed statistically to study frequencies, proportions, and associations using SPSS (v26, IBM, Armonk, NY). RESULTS: Forty-three patients (41 males and 2 females) with IOR fractures were treated between July 2019 and January 2021. The age range was 18 to 50 years. The etiology for trauma in all patients was a motor vehicle accident. Fifty-one fractures were classified into 6 types based on CT presentation. The single line fracture (concomitant with other bones) was the most prevalent (58.8%), while globe malposition was the most common clinical finding (35.8%). Lid malposition, globe malposition, and tethering of facial skin were associated with the type of IOR fracture (P = .04, P = .02, and P = .01, respectively). Excellent outcomes were scored in 32 and 25 fractures by the surgeon and patients, respectively, (P = .015 and P = .003). The inter-rater agreement between the surgeon and patient was significant (Kappa = 0.680; P < .001). CONCLUSIONS: Clinical findings in IOR fractures are dependent on the fracture type. Treatment of fractures based on their CT presentation produces effective management of signs/symptoms and improved treatment outcomes.

Evaluating the efficacy of disc repositioning in the management of high condylar fracture - A prospective clinical trial.

AIM: The aim of the study was to assess the role of disc repositioning in treating high condylar fractures. MATERIALS AND METHODS: Patients who reported to the Department of Oral and Maxillofacial surgery with high condylar fractures were recruited for this study, and randomized into two groups. The study group underwent 'disc repositioning during ORIF', while 'ORIF without disc repositioning' was performed for the control group. Patients were assessed for pain, mouth opening, clicking, and mandibular deviation (Helkimo clinical dysfunction Index), preoperatively and postoperatively (immediate and at 3 months). The position of the disc was assessed by MRI preoperatively and at 3 months postoperatively. RESULTS: 24 patients were included in the study, and divided equally into test (N = 12) and control (N = 12) groups. Descriptive statistics were used to find the means and standard deviations of the parameters, and inferential statistics to assess p-values, using an independent-sample t-test. At 3 months after surgery, 10 patients in the test group demonstrated absence of pain (mean 0.1 ± 0.3), while only one patient was pain free in the control group (mean 5.2 ± 2.3). There was a significant improvement in mouth opening in the study group (mean 37.4 ± 3.4) in comparison with the control group (mean 22.5 ± 9.5). The study group demonstrated favourable surgical outcomes for all parameters (p < 0.0001), aside from clicking. CONCLUSION: Within the limitations of the study, disc repositioning in high condylar fractures appeared to demonstrate a positive effect on TMJ function, and hence should be considered in appropriate indications.

The Conjunctival Turnover: A Simple and Effective Method for Sclero-Corneal Protection in Pre-Septal Transconjunctival Approach to the Orbital Floor.

Transconjunctival approaches have become the mainstay for most surgeons performing orbital wall reconstructions. Adequate care needs to be exercised for the protection of the cornea and sclera during these surgeries as they may involve placement of grafts or implants in situ apart from the routine intra-orbital dissections. The authors describe a simple technique of developing a conjunctival turnover flap for sclero-corneal protection in transconjunctival approaches to the orbit.

Evaluation of the efficacy of salmon calcitonin nasal spray on bone healing following open reduction and internal fixation of mandibular fractures - A randomized controlled trial.

The objective of this study was to assess the efficacy of calcitonin spray on bone healing following open reduction internal fixation (ORIF) of mandibular fractures. Fourteen patients were subdivided into a study group and a control group. A standardized surgical protocol for ORIF was followed. Postoperatively, salmon calcitonin nasal spray was administered to only the study group. The outcome parameters assessed were serum osteocalcin, pain, and radiographic bone healing. Serum osteocalcin was assessed pre- and postoperatively. Postoperative pain was documented using a visual analogue scale (VAS) on the 7th, 14th, 23rd, and 30th days. An orthopantomogram was used to score fracture healing at four time intervals, as follows: 1 - absence of callus; 2 - presence of minimal callus; 3 - considerable callus; and 4 - complete fusion of fracture. Pain scores were lower for the study group, with no pain from the fifth day, while the control group produced a mean score for day 5 of 2.43 ± 0.98 (p = 0.001). Mean postoperative serum osteocalcin levels were higher for the study group (67.82 ± 8.89) compared with the control group (57.69 ± 6.22; p = 0.029). Bone healing at 12 weeks postoperatively was level 4 for 28.6% of patients in the study group and level 3 for 71.4%. In comparison, 85.7% in the control group demonstrated level 3 healing, while 14.3% remained at level 2 (p = 0.462). Within the limitations of the study, it can be concluded that intranasal salmon calcitonin spray reduces postoperative pain and facilitates fracture healing, although its economic efficiency is still to be proven.

The Use of a Novel CAD-CAM Splint to Simplify Open Reduction and Internal Fixation of Mandibular Angle Fracture: A Technical Note.

Mandibular angle fractures are frequently encountered as they constitute an area of weakness. Complications after open reduction and internal fixation (ORIF) of angle fractures commonly arise due to improper reduction and fixation methods that fail to counteract the dynamic muscle forces present in this region. Conventional reduction methods such as digital manipulation, intermaxillary fixation, towel clip traction, and wiring are associated with various limitations. This technical note highlights the fabrication and use of a computer-aided designing/computer-aided manufacturing-generated splint for ORIF of a superiorly displaced mandibular angle fracture. The splint consisted of 2 components: (1) a distal tooth-borne component to guide the teeth into maximum intercuspation and (2) a proximal bone-borne component to reduce the angle fracture. This composite splint facilitates simultaneous restoration of occlusion as well as reduction of mandibular angle fractures. The advantages of this technique include the following: (1) easy fabrication of splint, (2) easy and precise anatomical reduction of angle fracture, and (3) less operative time.

Effectiveness of knotless suture as a wound closure agent for impacted third molar - A split mouth randomized controlled clinical trial.

AIM AND OBJECTIVE: This study was aimed to compare the effectiveness of 3-0 knotless barbed suture (polydioxanone) with 4-0 polyglactin 910 (vicryl) in achieving wound closure after impacted mandibular third molar surgery. MATERIALS AND METHODS: Patients with bilateral mandibular third molar impaction of similar difficulty index enrolled in the split mouth study. Wound closure was done using 3-0 knotless suture (30 × 30 cm) for the study group and 4-0 polyglactin 910 (vicryl) for the control group following extraction. Samples were allocated on the basis of simple randomization. The clinical outcome parameters that were measured were (1) time taken to achieve wound closure and hemostasis (2) postoperative mouth opening (3) swelling and (4) Pain. Data analysis involved descriptive statistics and paired t-tests (p < 0.05). IBM SPSS software (v.20.0) was used. RESULT: A total of 25 patients participated in the study (14 males and 11 females) with the mean age of 25.6 years. The mean time taken for wound approximation was 2.45 min and 4.1480 min (p-0.026) for the study and control groups respectively. The difference in mouth opening (p-0.015), VAS score(p-0.24), and swelling (p-0.041) were statistically significant on the first post-operative day in the study group than the control group indicating reduction in pain (p < 0.0001), swelling (p-0.033) and improvement in mouth opening (p < 0.0001) on seventh post-operative day in the study group compared to the control group. CONCLUSION: Knotless suture is an effective alternative to conventional sutures for intra oral wound closure as it reduces suturing time, facilitates effective wound closure and minimises knot related complications.

Mural Unicystic Ameloblastoma mimicking Odontogenic Cyst.

Unicystic ameloblastoma is considered a less aggressive variant of ameloblastoma with clinical and radiographic features mimicking a cyst. Herein, we present a case of unicystic ameloblastoma in a 20-year-old female who was clinically and radiographically diagnosed as an odontogenic cyst. Unicystic ameloblastoma and its subtypes are reviewed with special emphasis on the mural variant. The main aim of this case report is to highlight (1) the need of including an odontogenic tumor in the differential diagnosis of the unilocular, well-circumscribed radiolucent lesion by the clinicians (2) importance of serial sectioning of the specimen to identify the mural component if any present, and (3) following resection as the mode of treatment.
