Delayed-type inflammatory reactions (DIRs) secondary to tissue fillers are typically classified according to the time of appearance post-procedure and have various presentations including nodules, abscesses, edema, and discoloration.Currently, the treatment of these complications varies among physicians.Objective: The aim here of this study was to assess the knowledge and experience of practitioners in Israel who inject HA-based tissue fillers with respect to the management of late-onset procedural complications.Materials and Methods: A survey regarding management and treatment of late-onset inflammatory reactions was sent to 1120 physicians and dentists in Israel who practice tissue filler injections.

Results: Three hundred thirty-four out of the 1120 practitioners replied to the questionnaire.The majority of respondents were dentists (group A) comprising 31% of all respondents.Group B accounted for 31% of injectors and consisted of dermatologists bilstein shocks jeep xj (19%) and plastic surgeons (12%), and group C (38%) accounted for all other practitioners; 48.2% of all injectors indicated that they have not previously encountered a DIR, whereas 11.

4% responded that they have encountered more than 5 DIRs.In order to assess treatment management, we presented the injectors with a simulatory case of a woman with a late-onset complication.Most injectors referred the patient to the emergency department.When asked to establish a treatment plan, the majority of practitioners prescribed short-term oral steroids, ie, prednisone (35.

3%).A limited number of patients were treated with intra-lesional hyaluronidase (31.4%) injection as only 34% of injectors kept hyaluronidase at their clinic.Conclusion: The varied approach regarding the management of delayed type reactions to HA-based filler injections, reflected in our study, illustrates the existing ambivalence in the current literature regarding the management and therapy of late-onset complications.
