Brief summary

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.

Interventions

PROCEDUREpiezo-assisted prelacrimal apporach

The removal of the bone in the prelacrimal approach was done using piezo ultrasonic device

PROCEDUREconventional osteotomy prelacrimal approach

The removal of the bone in the prelacrimal approach was done using conventional osteotome and hammer
