Endoscopic modified Lothrop procedure

Instrument advances and improvements in endoscopic techniques offer rhinologists more choices in the surgical management of patients requiring revision after failing primary sinus surgery, especially in the area of the frontal recess and frontal sinus. The endoscopic modified Lothrop procedure creates a common nasofrontal drainage pathway by resecting the superior nasal septum and removing the frontal sinus floors bilaterally to create a common drainage space. By avoiding external incisions and offering better postoperative surveillance, the modified Lothrop procedure offers distinct advantages over open techniques, but it requires advanced surgical expertise and specialized instrumentation.
