Carolyn's window approach aims to remove the limitation created by the anterior-posterior depth to make a Draft 2a frontal sinusotomy easier for the surgeon. The approach is a 0° endoscope technique and provides an excellent view of the frontal sinus and recess.
Objectives
Due to the complexity and variety of the frontal recess and sinus anatomy, traditional Draf 2a frontal sinus surgery is challenging. The thickness of the nasofrontal beak and anterior–posterior dimensions of the frontal recess contribute to this complexity. Carolyn's window technique eliminates the limitation of anterior–posterior depth to facilitate a Draf 2a frontal sinusotomy. The approach is a 0° endoscope technique and provides an excellent view of the frontal sinus and recess. We describe Carolyn's window approach to frontal sinus surgery and the perioperative outcomes.
Methods
Consecutive adult patients in whom Carolyn's window technique was applied for frontal sinus dissection as part of the endoscopic management of both inflammatory and neoplastic disease were assessed. The primary outcome was frontal sinus patency. Secondary outcomes were surgical morbidity, defined as early (<90 days) or late (>90 days).
Results
Forty-five patients (49.1 ± 17.9 years, 48.9% Female) were assessed. All patients had successful frontal sinus patency (100% [95CI: 92.1%–100%]). Morbidities were adhesion (4.8%), crusting (2.4%), pain (1.2%), and bleeding (1.2%) in the early postoperative period. There were no other morbidities in the early and late postoperative periods.
Conclusion
Carolyn's window approach to frontal sinusotomy is a technique that evolves from previously described approaches. Successful frontal sinus patency with very low morbidities is achieved while still working with a 0° endoscope. The "axillectomy" performed simplifies frontal recess surgery by removing the anteroposterior diameter limitation and the dexterity required in angled endoscopy and instrumentation. The inferior-based lateral wall mucosal flap and free mucosal grafting expedite the mucosal healing process. Laryngoscope, 2023
