Abstract Introduction Zygomatic bone osteomyelitis is a rare condition having an incidence of 1.42%. Zygomatic osteomyelitis can be due to haematogenous infection with tubercle bacillus, facial bone fractures or very rarely due to an unknown aetiology like in our case. If surgically managed alone, it would lead to complete loss of zygomatic bone, causing high morbidity to the patient in terms of function and aesthetics like loss of globe support causing dystopia, loss of facial projection causing facial asymmetry. Restoration of facial symmetry and globe support would require extensive procedures such as non-vascular bone grafting or patient-specific implant placement or microvascular bone flap transfer. Materials and Methods Hyperbaric oxygen therapy (HBOT) was used to try and preserve the zygoma by promoting revascularisation. The patient received 100% oxygen at 2.5 absolute atmospheric pressure for 90 min, one session per day for 5 days in a week using a mask system in a multiplace chamber. The patient was reviewed clinically and radiologically after each 5 dives of HBOT sessions. After a total of 30 dives of HBOT, CT examination was repeated. & Prashanth Lowell Monis [email protected] Venkatraman Bhat [email protected] Samarth Shetty [email protected] Paul Christadas Salins [email protected] 1

There was partial reconstitution of cortical bone without any additional residual bone lesion. Minimal residual sequestra were noted. At this stage, the patient underwent conservative sequestrectomy in contrast to extensive surgery if HBOT was not contemplated. Conclusion HBOT has the potential to be a very useful adjunct in the treatment of osteomyelitis in head and neck surgery; however, there is a need for carefully designed trials, avoiding methodological bias due to the great variability of patients, infectious agents, antibiotic resistance, host factors, to broaden the evidence of this therapeutic modality.

Introduction Zygomatic bone osteomyelitis is a rare condition having an incidence of 1.42% [1]. Trauma and tuberculosis are the most common causes of zygoma osteomyelitis reported in the literature [2]. We present an unusual case of zygomatic bone osteomyelitis which was successfully treated by hyperbaric oxygen therapy (HBOT). Although adjunctive HBOT has been frequently used in the treatment of osteomyelitis of the jaws [3], this is the first reported case wherein HBOT is shown to be effective even in the case of Zygo
