Idiopathic osteomyelitis of the zygoma

Hyperbaric Oxygen Therapy in the Management of Zygomatic Bone Osteomyelitis

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. 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.

Transaxillary Nonendoscopic Subpectoral Augmentation Mammaplasty: A 10-Year Experience With Gel vs Saline in 2000 Patients-With Long-Term Patient Satisfaction Measured by the BREAST-Q

BACKGROUND

Transaxillary augmentation mammaplasty (TAM) is an option for patients who wish to avoid a visible breast incision from breast augmentation (BA).

OBJECTIVES

The authors compared TAM outcome data for gel and saline implants and evaluated patient satisfaction using the BREAST-Q patient-reported outcome measure (BQ).

METHODS

In this 10-year retrospective, comparative, and cross-sectional study, the authors reviewed results of saline implants placed with TAM in a surgeon's practice during the final 5 years of the moratorium of the US Food and Drug Administration (phase 1) and compared them with results for gel and saline implants placed with TAM during the 5 years after the moratorium (phase 2). Outcomes were assessed for the entire BA study population (n = 2430 for primary BA; 4860 implants); 670 patients completed and returned the BQ, from which postoperative satisfaction was evaluated.

RESULTS

BQ responses demonstrated a high rate of patient satisfaction, with outcomes comparable to those of other studies. The differences between the median BQ-assessed breast satisfaction and outcome satisfaction scores in the axillary and nonaxillary surgical groups were statistically significant, favoring axillary over nonaxillary. The difference in mean satisfaction scores was marginally significant between the 2 types of implants, favoring silicone gel. The incidence of surgical revision was 7.5% for the entire BA study population and 6.8% for the patients who underwent TAM.

CONCLUSIONS

TAM produces long-term patient satisfaction as measured by the BQ. Complication rates are similar to those of other studies. In the present study, patients who underwent TAM and thus had hidden incisions were more satisfied than patients whose incisions were visible.

Role of nasal endoscopy in chronic osteomyelitis of maxilla and zygoma: a case report

Osteomyelitis of the jaws was relatively common before the era of antibiotic therapy and preventive and restorative dentistry. Osteomyelitis is an acute or chronic inflammatory process that can involve cortical and trabecular aspects of bone or bone marrow. Cranial bones are infrequently involved, but spreading of inflammation with involvement of surrounding structures represents important risk, such as cerebral abscess, encephalitis, or meningitis. The mandible is more commonly involved than the maxilla. Dentogenic infections cause 38% of mandibular and 25% of maxillary involvement. Involvement of zygoma is very rare. Factors like viral fevers, malnutrition, malaria, anemia,tobacco chewing, immunodeficiency, osteopetrosis, Paget's disease of bone, and florid cemento-osseous dysplasia (FCOD) result in decreased vascularity of the affected bone, predisposing to the development of osteomyelitis. We present a case of osteomyelitis of left maxilla and zygoma with oroantral fistula in an immunocompetent adult male caused by dentogenic infection. The complete resolution of infection was gained with surgical treatment using nasal endoscope and antibiotic therapy. The aims of this paper are to illustrate diagnostic patterns, to report radiographic findings and surgical treatment using nasal endoscope in a case of osteomyelitis of maxilla and zygoma. The prognosis and cosmetic results are discussed.
