A retrospective epidemiological review of maxillofacial trauma in a tertiary care centre in Goa, India.

PURPOSE: Trauma accounts for the leading cause of morbidity and mortality worldwide in the present day and may rightly be called the new pandemic. The prominent nature of the face exposes it to various traumatic injuries. A timely, prompt diagnosis along with employment of correct and quick treatment greatly improves the outcome for these patients. The aim of this retrospective study was to analyse the characteristics of maxillofacial injuries over a decade. METHODS: The data were collected manually from the medical records of patients who reported to the tertiary centre from 1 January 2011 to 31 December 2019. All injured patients irrespective of age/gender with complete hospital records of clinical and radiographical diagnosis of maxillofacial injuries were included. The demographic data, etiology, site and type of injury, and seasonal variation were analyzed. Data were tabulated into six age groups (0-7 years, 8-18 years, 19-35 years, 36-40 years, 41-59 years, and >60 years). Five etiological factors, i.e. road traffic accidents, falls, assaults, sports-related, and occupational accidents, were further evaluated based on genders. Facial injuries were classified into six types: panfacial fractures, mandibular fractures (subcategorized), midface fractures (subcategorized), dentoalveolar fractures, dental injuries, and soft tissue injuries. The monthly and seasonal variation of the injuries was also charted. Data were expressed as frequency and percent. RESULTS: A total of 10,703 injuries were included from the tertiary centre from the period of 2011-2019, including 8637 males and 2066 females, with the highest occurrence of the injuries between 19 and 35 years. Road traffic accident was the principal etiological factor of the maxillofacial injuries in both genders (80.5%). This was followed by falls (9.6%), assaults (8.0%), occupational accidents (1.2%), and sporting injuries (0.7%). Midface fractures amounted for 52.5% (5623 fractures), followed by mandibular fractures (38.1%). CONCLUSION: The current study describes a change in the incidence of injuries along with variation in the demographic data. The implementation of safety gears and stricter traffic laws along with public awareness may aid in the reduction of maxillofacial injuries.

The Silicone Turkish Delight for Dorsal Augmentation in Rhinoplasty.

ABSTRACT: Rhinoplasties are the most challenging facial aesthetic procedures with the majority of the cases requiring dorsal augmentation either in the form of autogenous or alloplastic materials. Although autogenous grafts are the gold standard, these grafts have their innate issues such as donor site morbidity, occasional displacement, resorption, tendency to warp or develop sharp edges over time with increased perceptibility and clinical visibility of the graft with time. These issues were addressed by Erol in 2000 who advocated the use of finely diced autologous cartilage wrapped in a monolayer of surgical and termed it Turkish delight. This technique has been extensively modified by surgeons across the world with an attempt to forgo the use of autogenous grafts preventing donor site morbidity and replacing it with alloplastic materials. Silicon's inert nature, resorption resistance, absence of a secondary surgical site and economical value make it a widely utilized allograft augmentation option in Asian countries. The authors hereby present a modification of the original Turkish delight technique by utilizing diced silicone pieces amalgamated with 1 to 2 ml of autologous blood and wrapped in monolayer of surgicel (oxidized cellulose). The technique produced clinically stable results in 27 patients who were followed up for a period of 24 to 60 months (average 30 months). Improved pliability, negated risk of graft extrusion with no donor site morbidity are the key advantages of this technique over conventional autologous grafts and silicon block augmentation techniques. These results point towards the viability of the technique for performing dorsal augmentation in rhinoplasty.

Transbuccal versus transoral approach for management of mandibular angle fractures: a prospective, clinical and radiographic study.

OBJECTIVES: We compared the transbuccal and transoral approaches in the management of mandibular angle fractures. MATERIALS AND METHODS: Sixty patients with mandibular angle fractures were randomly divided into two equal groups (A, transoral approach; group B, transbuccal approach) who received fracture reduction using a single 2.5 mm 4 holed miniplate with a bar using either of the two approaches. Intraoperatively, the surgical time and the ease of surgical assess for fixation were noted. Patients were followed at 1 week, 3 months, and 6 months postoperatively and evaluated clinically for post-surgical complications like scarring, infection, postoperative occlusal discrepancy, malunion, and non-union. Radiographically, the interpretation of fracture reduction was also performed by studying the fracture gap following reduction using orthopantomogram tracing. The data was tabulated and subjected to statistical analysis. A P-value less than 0.05 was considered significant. RESULTS: No significant difference was seen between the two groups for variables like surgical time and ease of fixation. Radiographic interpretation of fracture reduction revealed statistical significance for group B from points B to D as compared to group A. No cases of malunion/non-union were noted. A single case of hypertrophic scar formation was noted in group B at 6 months postsurgery. Infection was noted in 2 patients in group B compared to 6 patients in group A. There was significantly more occlusal discrepancy in group A compared to group B at 1 week postoperatively, but no long standing discrepancy was noted in either group at the 6 months follow-up. CONCLUSION: The transbuccal approach was superior to the transoral approach with regard to radiographic reduction of the fracture gap, inconspicuous external scarring, and fewer postoperative complications. We preferred the transbuccal approach due to ease of use, minimal requirement for plate bending, and facilitation of plate placement in the neutral mid-point area of the mandible.

Use of regenerative tissue matrix as an oral layer for the closure of recalcitrant anterior palatal fistulae: a pilot study.

OBJECTIVES: To evaluate the effectiveness of regenerative tissue matrix (Alloderm) as an oral layer for difficult anterior palatal fistula closure. MATERIALS AND METHODS: The authors have tested the feasibility of a novel surgical technique of adding a regenerative tissue matrix (Alloderm) as an oral layer for closure of recalcitrant large anterior palatal fistulae and report the outcome of the first 12 patients in this pilot study. Patients with recurrent large fistula who otherwise would require either a local pedicled flap, free flap, or an obturator were treated with this technique and followed up for at least 6 months to monitor the progress of healing. RESULTS: Of the 12 patients, 8 patients (66.7%) had complete closure of the fistula, and 2 patients (16.7%) showed reduction in size of the fistula to the extent that symptoms were eliminated, for an overall success rate of 83.3% (10/12 patients). Premature graft loss and recurrence of the fistula were noted in 2 patients (16.7%). CONCLUSION: Alloderm provided an adequate barrier allowing healing to occur unimpeded and allowed closure of the palatal fistula. In our experience, this new technique using regenerative tissue matrix as an adjunct to the oral layer in large anterior palatal fistula has an advantage compared to other more invasive complex procedures and has been shown to provide satisfactory results.

Comparison of ondansetron and granisetron for antiemetic prophylaxis in maxillofacial surgery patients receiving general anesthesia: a prospective, randomised, and double blind study.

OBJECTIVES: To compare the efficacy of intravenous ondansetron (4 mg, 2 mL) and granisetron (2 mg, 2 mL) for preventing postoperative nausea and vomiting (PONV) in patients during oral and maxillofacial surgical procedures under general anesthesia. MATERIALS AND METHODS: A prospective, randomized, and double blind clinical study was carried out with 60 patients undergoing oral and maxillofacial surgical procedures under general anesthesia. Patients were divided into two groups of 30 individuals each. Approximately two minutes before induction of general anesthesia, each patient received either 4 mg (2 mL) ondansetron or 2 mg (2 mL) granisetron intravenously in a double blind manner. Balanced anesthetic technique was used for all patients. Patients were assessed for episodes of nausea, retching, vomiting, and the need for rescue antiemetic at intervals of 0-2, 3, 6, 12, and 24 hours after surgery. Incidence of complete response and adverse effects were assessed at 24 hours postoperatively. Data was tabulated and subjected to statistical analysis using the chi-square test, unpaired t-test, or the Mann-Whitney U-test as appropriate. A P-value less than 0.05 was considered statistically significant. RESULTS: There was no statistically significant difference between the two groups for incidence of PONV or the need for rescue antiemetic. Both study drugs were well tolerated with minimum adverse effects; the most common adverse effect was headache. The overall incidence of complete response in the granisetron group (86.7%) was significantly higher than the ondansetron group (60.0%). CONCLUSION: Granisetron at an intravenous dose of 2 mg was found to be safe, well tolerated, and more effective by increasing the incidence of complete response compared to 4 mg intravenous ondansetron when used for antiemetic prophylaxis in maxillofacial surgery patients receiving general anesthesia. Benefits of granisetron include high receptor specificity and high potency, which make it a valuable alternative to ondansetron.

Management of human bite injury of the upper and lower eyelids: a rare case report.

Human bite injury to the eyelid is extremely rare and poses a significant challenge in surgical reconstruction. We report an extremely rare case of human bite injury to the eyelid in a 43-year-old male with approximately 60% full thickness loss of the upper eyelid and 80% to 90% full thickness loss of the lower eyelid and its successful reconstruction using the local advancement cheek flap.

Tissue Engineering: Step Ahead in Maxillofacial Reconstruction.

Within the precedent decade, a new field of "tissue engineering" or "tissue regeneration" emerge that offers an innovative and exhilarating substitute for maxillofacial reconstruction. It offers a new option to supplement existing treatment regimens for reconstruction/regeneration of the oral and craniofacial complex, which includes the teeth, periodontium, bones, soft tissues (oral mucosa, conjunctiva, skin), salivary glands, and the temporomandibular joint (bone and cartilage), as well as blood vessels, muscles, tendons, and nerves. Tissue engineering is based on harvesting the stem cells which are having potential to form an organ. Harvested cells are then transferred into scaffolds that are manufactured in a laboratory to resemble the structure of the desired tissue to be replaced. This article reviews the principles of tissue engineering and its various applications in oral and maxillofacial surgery.

Hyperactive Dental Lamina in a 24-Year-old Female - A Case Report and Review of Literature.

An extra tooth to the normal formula of teeth sequence in any region of dental arch is regarded as Supernumerary teeth (ST). The reasons are still not clearly known, one of them being dichotomy of tooth bud, but the more accepted reason is the hyperactivity theory. Supernumerary teeth are present more in permanent dentition than in primary dentition and can present as a single entity or multiple, unilaterally or bilaterally, impacted or erupted, in either or both the dental arches. This article discusses the supernumerary teeth in detail with a case discussion of a non-syndromic 24-year-old girl, with six ST (bicuspids) present in all the four quadrants. In the mandible, ST's showed a classical clustered flower like presentation. The interesting feature in the presented case was the sequential orthopantomographs taken at various ages of the patient that showed continuous development of STs in all four quadrants, thus pointing to the theory of hyperactive dental lamina or atavism. An electronic search was conceded in PubMed, Cochrane Library and google scholar databases, and articles dated between December 1932 and December 2012 were selected to review the occurrence patterns of supernumerary teeth in non-syndromic cases.

Bioactive Glass S53P4 versus Chlorhexidine Gluconate as Intracanal Medicament in Primary Teeth: An In-vivo Study Using Polymerase Chain Reaction Analysis.

BACKGROUND: Bacteria have long been recognized as the primary etiology for pulpal and periapical lesions, which necessitates the elimination of bacteria from the root canal system. In primary teeth, irrigation and debridement is the main protocol required to disinfect the canal. Biomechanical preparation cannot be vigorously done on the primary teeth due to anatomical barrier such as thin and flared roots. This calls for the use of an effective intracanal medication that will assist disinfection of root canal system. Aim of the study was to examine the in-vivo susceptibility of root canal bacteria to chlorhexidine (CHX) gluconate-1% gel and bioactive glass (BAG) S53P4 when used as intracanal medicaments using polymerase chain reaction (PCR). METHODOLOGY: PCR (analysis used oligonucleotide primers of Escherichia coli) was used to detect and compare the microbial load reduction after medication of 14 teeth for a week with either CHX gel - 1% or BAG S53P4. The pre and post microbial load was checked in the form of colony forming units. When analysis was done, a statistically significant difference was observed between the two groups. RESULTS: The study revealed that both medicaments caused a considerable amount of microbial load reduction. BAG S53P4 caused much more reduction than CHX 1% gel. Statistical analysis showed a significant difference between the two groups. CONCLUSION: BAG S53P4 has superior antibacterial property as compared to CHX 1% gel.
