Micro-Direct Laryngoscopy: Surgical Treatment of Voice Disorders
Modern laryngeal microsurgery developed rapidly in the 1980s in conjunction with a better understanding of vocal fold anatomy. It is based on the premise that surgery should be designed to remove pathology without provoking scar formation, or in other words, without stimulating fibroblasts in the intermediate layer of the lamina propria or deeper.

Resection of the Anterior Ethmoid Bulla
with the MicroFrance™ MicroBite™ Through-Cutting Forceps
The "grasp and tear" surgical techniques used in the past to resect the anterior and medial wall of the ethmoid bulla are often responsible for the inadvertent stripping of intact mucosa from the lamina papyracea. The resulting exposed bone often forms granulation tissue and adhesions, which complicates the healing process. Scarring in the middle meatus and anterior ethmoid cavity contributes to surgical failure.
The MicroFrance MicroBite Through-Cutting Sinus Forceps have been designed to precisely resect the anterior and medial wall of the ethmoid bulla without damage to delicate mucosa overlying the lamina papyracea. These forceps are sized appropriately for pediatric or adult surgery, and their precise cutting action allows for sharp resection of mucosa without stripping mucosa.

Mini-Trephination and Irrigation of the Frontal Sinus
Patients with frontal sinus disease most commonly present to the otolaryngologist with pressure in the frontal region. Frontal sinus disease is suggested by abnormalities in the nasal frontal recess on nasal endoscopy and is confirmed with coronal CT scans.
