Pharmacovigilance comment: the suspect product was reported as an unspecified hyaluronic acid filler; however, we cannot exclude that one of our hyaluronic acid filler products have been used.The serious event of bacterial infection and the non-serious events of erythema, nodule, inflammation, swelling, pain, induration and purulent discharge at implant site and chronic sinusitis were considered expected and possibly related to the treatment.The non-serious events of dental cyst and chronic sinusitis were considered unexpected and unrelated.Potential contributory factors include injection technique, dental cyst and chronic odontogenic sinusitis.Serious criteria include the need for multiple medical interventions.The case meets the criteria for expedited reporting to the regulatory authorities.Engineering evaluation: the information in this single case does not suggest involvement of a nonconforming product or quality problem and will not initiate a corrective or preventive action.Manufacturer narrative: lot number was not reported.Exemption: (b)(4).
