Closed Piezo Preservation Rhinoplasty

Aesthetic Plast Surg. 2022 Jun;46(3):1342-1350. doi: 10.1007/s00266-021-02751-0. Epub 2022 Feb 15.


Background: The application of piezoelectric instruments (PEIs), which made the work with the nasal pyramid a predictable and controlled stage of rhinoplasty, is still more often related to the open approach. The intranasal approach is constantly associated with standard methods of osteotomies, including percutaneous techniques, which represent certain limitations in working with the bony vault without managing the surface and thickness of its walls and the risk of uncontrolled fractures.

Objectives: The authors apply PEIs for osteotomies and reshaping of the nasal pyramid through the closed approach with preservation rhinoplasty and complete subperichondrial and subperiosteal dissection.

Methods: The technique of working with the nasal pyramid using PEIs with the closed approach is described. The patients were grouped according to the methods of nasal pyramid surgery-Push Down (PD), Let Down (LD) with Rhinosculpture (Rs), or the combinations. The results of the surgeries with the application of PEIs on 134 patients were retrospectively analyzed before the surgery and 12 months after it according to the "Rhinoplasty Outcome Evaluation" (ROE).

Results: The average age of the patients was 28, 125 were female and 9 were male. The patients' satisfaction was excellent in 96% of all the cases included. There were two cases with residual humps and four cases with residual asymmetries in cases of severe deviations.

Conclusions: Via intranasal approach, it is possible to use PEIs for managing the bony vault in primary rhinoplasty. The limitations for this technique are underdevelopment of the nasal dorsum, cleft lip nose situations, post-traumatic and previous rhinoplasty cases.
