Efficacy of Piezosurgery Versus Conventional Osteotomy in Prelacrimal Approach Targeting Different Maxillary Sinus Pathologies

Efficacy of Piezosurgery Versus Conventional Osteotomy in Prelacrimal Approach Targeting Different Maxillary Sinus Pathologies: a Randomized Controlled Trial

The prelacrimal recess approach is a minimally invasive approach to maxillary sinus lesions. The current study aimed to evaluate the efficacy of piezosurgery versus conventional osteotomy while performing a prelacrimal apporach.

Inclusion Criteria:

1. Any maxillary sinus pathology (recurrent Antrochoanal polyp, inverted papilloma, fungal ball, allergic fungal sinusitis, CRSwNP, CRSeNP, orbital floor fracture, etc).
2. Favorable prelacrimal recess (Type II or III Simmen classification)
3. Age> 18 years.
4. No gender limitation.

Exclusion Criteria:

1. patients with malignant sino-nasal tumors.
2. patients unfit for surgery
