Alterations in Nasal Sensibility Following Calcium Hydroxyapatite Dorsal Augmentation.

Background: There are a many types of filler products that surgeons used for soft tissue augmentation. Soft Tissue Fillers, also known as injectable grafts, is a medical device implants. One of the materials used in soft tissue fillers is calcium hydroxylapatite (CaHA) that is commonly used for treating nasal deformities and nasal reshaping too. Calcium hydroxylapatite is a kind of mineral that can be found in human teeth and bones. It is considered long-lasting but nonpermanent filler and is biocompatible with human tissue. Aim: The aim of this study is to measure the alterations in sensibility and patient satisfaction following CaHA filler injection. Patient/Methods: In a prospective study, 30 patients who underwent CaHA filler injections from January to December 2016 at a Private Tertiary Care Hospital in Riyadh, Saudi Arabia were included. Results: Means and standard deviations were measured for pressure threshold values at each test area preprocedure 2 weeks after procedure (Table 1). Alterations between pre and postprocedure values were verified using the match-paired Student t test preprocedures. None of the patients had any subjective sensory symptoms. Majority of patients were extremely satisfied with the results. Conclusion: With correct anatomic knowledge and precise technique in doing the CaHA gel injection procedure, nasal sensibility will not be altered. In addition, injection of CaHA gel can be valuable tool for plastic surgeons to consider for nasal reshaping. (C) 2017 by Mutaz B. Habal, MD.
