title: Application of piezoelectric device in endoscopic sinus surgery.
abstract: New applications of piezoelectric device have been already documented from otologic and ophthalmic endoscopic studies. The authors describe a first experience in endoscopic sinus surgery with piezosurgery to approach the paranasal sinus. Patients involved in this study presented for rhinogenous headache, rhinorrhea, nasal obstruction, and sinusitis. Radiological studies such as computed tomography of paranasal sinus and a correct clinical examination with a rigid endoscope 0 degrees were carried out, to exclude from the procedure patients with polyposis or other soft-tissue diseases. In fact, because of piezosurgery properties of micrometric and selected cutting on mineralized tissues, it has been used only to treat bone or cartilage anomalies of nasal sinus. The main advantages of the technique include soft-tissue protection and optimal visibility in the surgical field with decreased blood loss. From this preliminary report, the stability of mucous membrane previously cut has been documented by endoscopic follow-up, and the resolution of the main symptom of headache was referred. The main indications for piezosurgery shown in literature are in oral surgery, such as sinus lift, bone graft harvesting, osteogenic distraction, ridge expansion, endodontic surgery, and periodontal surgery. Other applications have been shown in otology, neurosurgery, ophthalmology, and orthopedics. Authors describe as a promising technique the piezoelectric device use in functional endoscopic paranasal sinus surgery in selected cases, with a minimal mucosal approach and thus the preservation of ventilation.
