Osteonecrosis of the Jaws: An Update and Review of Literature.

Aim: To provide a concise review on risk factors, stages, pathophysiology, prevention and possible treatment options for both MRONJ and ORN individually. Methods: The review was conducted according to the 'Preferred Reporting Items for Systematic Reviews and Meta-Analyses' (PRISMA) guidelines. A comprehensive search of the PUBMED, Ebsco, SCOPUS, WEB OF SCIENCE and NDH for articles published up until 2021 was performed. After screening and full text analyses, 44 studies were included in this review. Definition, risk factors, etiology, symptoms, stages, pathophysiology, prevention and possible management options were explored and highlighted in this article. Results: Three studies described osteonecrosis of jaw (ONJ) in general, 15 studies described ONJ associated with radiotherapy and 26 studies described ONJ associated with medications. Both the two conditions (ORN) and (MRONJ) have relatively similar clinical presentations clearing the fact that a resemblance in clinical presentations does not necessarily denote a similar pathophysiology. Conclusion: However, various advancements have been made in the control and management of ONJ, but until and unless need for high tumoricidal doses exists, ONJ will certainly continue to remain as a clinical challenge demanding satisfactory treatment to improve the quality of life of the patient.

Ophthalmic Complications in Maxillofacial Trauma: A Prospective Study.

OBJECTIVES: To determine the incidence and types of ophthalmic complications associated with maxillofacial trauma over a period of 24 months. METHODS: An institutional prospective study was conducted on 62 patients presenting with maxillofacial trauma to study the correlation between facial trauma and ophthalmic complications. RESULTS: Road traffic accidents were reported to be the primary etiologic factor for most trauma cases studied. Zygomaticomaxillary complex (ZMC) fracture was associated with more ophthalmic complications while fractures involving the orbital rims and walls were associated with severe complications. CONCLUSIONS: Maxillofacial trauma, particularly those associated with midface, including ZMC fracture, Le Fort II, Le Fort III, and naso-orbito-ethmoidal fractures, can commonly cause ophthalmic complications and blindness in rare cases. Hence, every patient with maxillofacial trauma should undergo an ophthalmic examination and should be placed under close observation for necessary treatment when required.

Evaluation of Retro Mandibular Approach to Open Reduction and Internal Fixation of Condylar Fractures: A Cross-sectional Study.

PURPOSE: The present study was carried out to evaluate the usefulness of mini retromandibular approach on accessibility, scarring and stability in open reduction and internal fixation of sub condylar fractures. MATERIALS AND METHODS: Fifteen patients underwent open reduction and rigid fixation of middle and low subcondylar fractures, with mini-retro mandibular approach. RESULTS: No signs of infection were observed in any patient postoperatively. Surgical scar was imperceptible and esthetically acceptable in all the cases. Out of 15 patients, only one patient had discrepancy in occlusion and after 2 months satisfactory centric occlusion was achieved. Salivary fistula (parotid fistula) was observed in 3 cases within 1 week postoperatively, which was treated spontaneously with the use of hypertonic saline. Transient facial nerve weakness was observed in 2 patients, in one patient it resolved in 4 weeks postoperatively and in second patient 3 months postoperatively. Mouth opening increased in all the patients with time. Average mouth opening at 1 week interval was 19.6 mm, at 2 months interval 28.2 mm, and after 6 months 38.33 mm suggesting that mouth opening gradually increased with time. At the end of 2 months postoperatively none of the patients had any restriction in lateral movements. At 2 months postoperatively 4 patients had deviation but none of the patients had any deviation 6 months postoperatively. CONCLUSION: It is evident from the results of our study that open reduction and internal fixation using mini-retromandibular approach is good treatment option in management of mandibular condylar fractures.

Management of parotid fistula using hypertonic saline.

Parotid fistula is a very rare, unpleasant and painful complication following surgery in the maxillofacial region. Although there is consensus in the literature that acute parotid injury must be explored primarily and all injured structures be repaired accurately, the treatment of the chronic injury is controversial. Numerous methods of treatment, conservative as well as aggressive, have been described with varying success and morbidity. This paper presents a simple but effective and conservative method of treating this complication with the use of hot hypertonic saline.
