Frontal Bone Fractures and Frontal Sinus Injuries: Treatment Paradigms.

BACKGROUND

Timely, expeditious and appropriate management of Frontal bone fractures and associated Frontal Sinus (FS) injuries are both crucial as well as challenging. Treatment options vary considerably, depending upon the nature, extent and severity of these injuries as well as operator skill, expertise and experience. In cases of posterior table fractures of the Frontal Sinus, literature reports have in general, propounded direct visualization and exploration of the sinus via a bifrontal craniotomy, followed by sinus cranialization.

AIMS AND OBJECTIVES

To review the standard protocols of management of Frontal bone fractures and Frontal Sinus injuries. To assess the efficacy of a more conservative approach in the management of outer and inner table fractures of the FS.

MATERIALS AND METHODS

Contemporary and evolving management protocols and changing treatment paradigms of different types and severities of frontal bone fractures and frontal sinus injuries, have been presented in this case series. A useful Treatment Algorithm has been proposed to efficiently and effectively manage these injuries.

RESULTS

In the present case series, effective and satisfactory results could be achieved in cases of significantly displaced inner and outer table fractures of the Frontal sinus by a more conservative protocol comprising of open reduction and internal fixation carried out via the existing scar of injury, without having to resort to the more radical intracranial approach and sinus cranialization. Nevertheless, presence of complicating factors such as cerebrospinal fluid rhinorrhea, evidence of meningitis or the development of encephalomeningocoeles necessitated the standard protocol of sinus exploration and its cranialization or obliteration.

CONCLUSION

Management protocols of Frontal Sinus injuries vary, based on aspects such as the timing of presentation and intervention, degree of injury sustained, concomitant associated Craniomaxillofacial injuries present, presence of complicating factors or Secondary/Residual deformities & Functional debility, and need to be decided upon on a case to case basis.
