Utilization of frontal balloon sinuplasty in pediatric complicated acute rhinosinusitis (ARS) is demonstrated to be a safe and expedient alternative to other procedures such as trephination or functional endoscopic sinus surgery (FESS) in this case series. We performed a retrospective review of six pediatric cases of frontal balloon sinuplasty for ARS with intracranial complications at a tertiary academic center. Patients underwent unilateral ( = 5) or bilateral dilation ( = 1) in addition to functional endoscopic sinus surgery (FESS) including anterior ethmoidectomy ( = 5) and maxillary antrostomy ( = 6).

Spontaneous pneumomediastinum (SPM) is an unusual clinical entity that most frequently follows episodes of increased intrathoracic pressures. While typically a benign condition, potentially fatal complications of SPM must be considered and ruled out with each case. We aim to present the first case of croup-associated SPM in the otolaryngology literature and to discuss clinical, diagnostic and management principles.
