Objectives: The Draf III frontal sinusotomy is an established surgical procedure with an important role in the surgical management of recalcitrant chronic rhinosinusitis (CRS). In 2012, the outside-in approach to the Draf III was described as a safe and efficient procedure. Smell recovery in inflammatory CRS is challenging, and to date there is limited evidence suggesting that Draf III improves patient-reported olfactory dysfunction from CRS., Methods: A consecutive series of patients who underwent an outside-in Draf III for inflammatory CRS by a single, tertiary rhinologist were reviewed. Patients were excluded if the Draf III was performed for noninflammatory conditions. Postoperatively, patients were maintained on long-term corticosteroid irrigations, and adherence was assessed. Prospectively collected data included patient demographics, a visual analogue scale for smell, overall Sinonasal Outcome Test Score (SNOT-22), global nasal function score, and a clinician-graded clinical outcome score., Results: One hundred and four patients (41.1% female) aged 54 ± 12 years underwent an outside-in Draf III. The median follow-up time was 30.6 months (range 12.2-72.1). The majority of patients rated their smell loss as moderate or worse preoperatively; however, this was significantly improved at postoperative review (71.2% vs. 27.6%; Kendall tau-b, P < 0.01). The SNOT-22 score improved after surgery (2.32 ± 1.09 vs. 0.78 ± 0.69, P < 0.0001). Medication adherence was significantly associated with improved clinical outcome score (Kendall tau-b, P < 0.004). Aspirin exacerbated respiratory disease was found to be a significant risk factor predicting poor clinical outcome on univariate analysis (Odds Ratio = 4.69 (1.03-21.2), P = 0.04)., Conclusion: The outside-in Draf III appears to facilitate sustained, meaningful improvement in several self-reported outcomes, including smell. However, further study and comparison to less aggressive surgery will be required to confirm its true benefit., Level of Evidence: Level 4 Laryngoscope, 129:25-30, 2019., (© 2018 The American Laryngological, Rhinological and Otological Society, Inc.)

Background: Effective mucus lavage and delivery of topical pharmaceuticals are central to successful management of chronic rhinosinusitis (CRS). The frontal sinus remains difficult to penetrate with topical therapies. This study evaluates the benefit of Draf III frontal dissection compared to traditional Draf IIa for distribution of topical therapies., Methods: Fresh human cadaver heads were dissected sequentially with Draf IIa frontal sinusotomy and then Draf III procedures. Each cavity was irrigated with pediatric (120 mL) and adult (240 mL) irrigation bottles with 1/1000 10% fluorescein-labeled free water in 2 fixed positions (vertex and Frankfort horizontal). An endoscope at a fixed position within the frontal sinus recorded frontal sinus and frontal recess penetration. The images then underwent blinded evaluation of fluid distribution scored as 0 to 4 (nasal cavity only, frontal recess, medial one-half, lateral one-half, and lavage). Ordinal distribution score was analyzed with Kendall's tau-b., Results: Eight specimens (age 76 ± 11.2 years; 50% female) were assessed. Draf III was superior to Draf IIa in ability to achieve frontal sinus distribution of irrigation (90.6% vs 50.1%, p < 0.001). Vertex head position improved distribution (90.6% vs 50.1%, p < 0.001), was synergistic with Draf III (100% with 87.5% lavage, p < 0.001), but was unable to overcome Draf IIa (81.2% with 25% lavage, p < 0.001). Irrigation volume trended toward improved distribution with larger volume irrigations., Conclusion: Successful treatment of sinonasal disease may require postoperative delivery of topical therapies. Draf III frontal sinusotomy achieves superior topical access, and access to the frontal sinus with Draf IIa appears limited, despite large volumes and positioning., (© 2016 ARS-AAOA, LLC.)

Objectives/hypothesis: Ostiomeatal complex (OMC) occlusion may play a role in the pathogenesis of some chronic rhinosinusitis (CRS) subgroups, but its role in diffuse mucosal inflammation is strongly debated. The association between radiological OMC occlusion and its draining sinuses in patients with eosinophilic rhinosinusitis (ECRS) compared to non-ECRS is investigated., Study Design: Case-control study., Methods: Patients with CRS who underwent endoscopic sinus surgery were investigated. Preoperative computed tomography scans were evaluated. Structured histopathology reporting was performed. The study group was patients with high tissue eosinophil >10/high power fields (HPF), and the control group was patients with low tissue eosinophil ≤ 10/HPF. The radiological relationship of OMC occlusion to the draining sinuses was analyzed in each group., Results: Seventy patients with a mean age of 49.7 ± 14.1 years were analyzed. Forty-one (58.6%) patients had high tissue eosinophil >10/HPF. All patients with ECRS had maxillary disease, and there were 36.2% without OMC occlusion. There was no association of OMC occlusion to either the anterior ethmoid (ECRS: odds ratio [OR], 1.84; 95% confidence interval [CI], 0.24-14.14; P = .55; non-ECRS: OR, 1.57; 95% CI, 0.34-7.33; P = .56) or frontal sinuses (ECRS: OR, 0.67; 95% CI, 0.12-3.82; P = .65; non-ECRS: OR, 1.58; 95% CI, 0.45-5.54; P = .47). For patients with non-ECRS, maxillary sinus diseases was present in 96.2% of those with OMC occlusion and 50% of those without (OR, 25.0; 95% CI, 2.77-226.08; P < .001)., Conclusions: OMC occlusion is not associated with draining sinuses for patients with ECRS. Simple surgical interventions directed at the OMC are unlikely to be of benefit to this CRS subgroup., Level of Evidence: 3b., (Copyright © 2013 The American Laryngological, Rhinological and Otological Society, Inc.)

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, 133:2496–2501, 2023 [ABSTRACT FROM AUTHOR]

Background: Delivery of topical pharmacotherapy to the paranasal sinuses remains integral to the management of chronic rhinosinusitis. The frontal sinus remains a difficult access site for irrigations, often limited by its position relative to the nostril and ethmoid sinus. In view of the previous demonstration of improved frontal sinus irrigation with Draf III vs Draf IIa, in this work we sought to evaluate topical access of Draf IIb relative to Draf IIa and Draf III modification of the frontal sinus outflow tract. Methods: Unfixed human cadaver heads were dissected using Draf IIa, Draf IIb, and Draf III frontal sinusotomies. Draf IIa, Draf IIb, and Draf III frontal sinusotomies were performed in progressive sequence on each cadaver head. Nasal irrigation fluid access to the frontal sinus was tested after each successive frontal sinus intervention. Irrigations were performed using Frankfort horizontal and vertex positioning. Blinded reviewers were then asked to evaluate nasal irrigation access based on an ordinal scale. Results: Eight cadaveric specimens (age, 78 ± 12.3 years; 62.5% female) were assessed. The greatest distribution scores were recorded by Draf III, then IIb, and then IIa (90.7% vs 81.3% vs 50.1%; p < 0.001). Similarly, the rate of lavage was greatest with Draf III (50% vs 12.5% vs 12.5%). Vertex positioning and increasing volume trended toward improved distribution but did not reach statistical significance. Conclusion: Adequate delivery of topical therapy to the paranasal sinuses by nasal irrigation remains critical in the postoperative state. Although increasing the dimensions of the frontal recess improves nasal irrigation delivery, the Draf III procedure provides the optimal delivery of pharmacotherapy in those with frontal sinus disease.
