Application of piezoelectric device in endoscopic sinus surgery

Area of Science:

• Otorhinolaryngology
• Surgical Technology

Background:

• Piezoelectric devices have expanded applications in otologic and ophthalmic endoscopic procedures.
• Endoscopic sinus surgery (ESS) is a common treatment for various sinonasal conditions.

Purpose of the Study:

• To report the initial experience of utilizing piezosurgery in functional endoscopic paranasal sinus surgery (FESS).
• To evaluate the safety and efficacy of piezosurgery for bone and cartilage anomalies within the nasal sinus.

Main Methods:

• Patients with symptoms like rhinogenous headache, rhinorrhea, and nasal obstruction underwent computed tomography (CT) and clinical examination.
• Piezosurgery was employed specifically for bone or cartilage anomalies, excluding patients with polyposis or soft-tissue diseases.
• Rigid endoscopy (0 degrees) was used for examination and surgical visualization.

Main Results:

• Piezosurgery demonstrated micrometric cutting on mineralized tissues, ensuring soft-tissue protection.
• The technique provided optimal surgical field visibility with reduced blood loss.
• Endoscopic follow-up confirmed mucosal stability, and patients reported resolution of headache.

Conclusions:

• Piezosurgery is a promising technique for selected cases of FESS, particularly for bone anomalies.
• The minimal mucosal approach preserves sinonasal ventilation and reduces complications.
• This approach enhances surgical precision and patient outcomes in sinonasal surgery.
