Sino-Cutaneous Fistula After Using Medpor Implant in Orbital Blowout Fracture.

In surgical repair of orbital fracture, implant materials play an important role in restoring the functional and anatomic structure of the orbit. Alloplastic implant materials are widely used for this surgery, but they have the risk of complications such as infections, pain, and extrusion. Because they are artificial implants, infection can occur more than autologous implants and is the most challenging problem to manage.

Role of posterior auricular muscle to prevent protruding ear after retroauricular ear surgery.

Objective: The posterior auricular muscle (PAM) functions in ear projection in normal position and is severed during the retroauricular approach, and some patients complain of a protruding ear postoperatively. This study was designed to determine whether suturing of the severed PAM reduces pinna projection after the retroauricular approach.

Methods: In a prospective controlled study, we enrolled 91 patients with chronic otitis media, all of who underwent canal wall up mastoidectomy with tympanoplasty via retroauricular approach.
