Endoscopic sinus surgery is an effective intervention at improving quality of life for patients with medically refractory chronic rhinosinusitis. The evidence supporting frontal sinusotomy is limited to single institution case series. However, the data for Draf IIa frontal sinusotomy do demonstrate that most patients experience lasting frontal sinus patency on postoperative endoscopic examination and improvements in quality of life. Salvage endoscopic frontal sinus surgery via a Draf III shows high rates of neo-ostium patency and subjective improvements in symptoms at a 2-year time point in case series...

INTRODUCTION: Cerebrospinal fluid (CSF) leak occurs in 1-11% of endoscopic Draf III, or endoscopic modified Lothrop, procedures. CSF leak can occur during surgery during a superior nasal septectomy. This study investigated whether the posterior edge of the nasofrontal beak (NFB) at the level of the internal frontal ostium is a safe landmark to use to avoid skull base injury when beginning the superior septectomy. METHODS: Preoperative computed tomography maxillofacial scans were reviewed from 100 patients from the University of Pennsylvania sinus surgery data base...

OBJECTIVES/HYPOTHESIS: The Draf IIb aims at widening the frontal sinus drainage in a minimally invasive fashion. However, this technique is associated with a high stenosis rate. Hence, local nasal flaps have been recently introduced or designed to speed up mucosal healing and prevent scarring. STUDY DESIGN: The objective of this study was to present the septoturbinal flap (STF), its use in a Draf IIb, and to examine postoperative outcomes of this procedure. METHODS: From an initial pool of 48 patients with frontal sinus disease to be treated with a Draf IIb, we prospectively selected 46 (95...

BACKGROUND: Investigations into the distribution of sinus irrigations have been limited by labor-intensive methodologies that do not capture the full dynamics of irrigation flow. The purpose of this study was to validate the accuracy of a computational fluid dynamics (CFD) model for sinonasal irrigations through a cadaveric experiment. METHODS: Endoscopic sinus surgery was performed on 2 fresh cadavers to open all 8 sinuses, including a Draf III procedure for cadaver 1, and Draf IIb frontal sinusotomies for cadaver 2...

BACKGROUND: Extended frontal surgery techniques are often required when maximal medical therapy and standard endoscopic surgical approaches fail in patients. Although outcomes of the Draf III (modified Lothrop) procedure have been widely reported, postoperative outcomes and indications for the Draf IIB frontal sinusotomy have been relatively underreported. We presented our institution's experience with the Draf IIB procedure. METHODS: Patients who underwent the Draf IIB frontal sinusotomy between 2007 and 2012 were identified by retrospective chart review...

BACKGROUND: The management of frontal sinus disease still remains a challenging issue for rhinologists. Although endoscopic frontal sinus surgery has significantly advanced over the past years, there are some conditions in which the external approaches are still necessary. Recently, the increasing experience in endoscopic sinus surgery together with important technologic advancements have allowed expansion of the indications for selected lesions localized more and more lateral into the frontal sinus...

OBJECTIVES/HYPOTHESIS: Topical sinus irrigations play a critical role in the management of sinonasal disease, and the improvement in irrigant penetration into the sinuses postoperatively greatly contributes to the success of endoscopic sinus surgery. Prior investigations on postoperative sinus irrigations have been mostly limited to cadaver studies, which are labor intensive and do not capture the full dynamics of the flows. A pilot study was conducted to investigate the impact of surgery on sinus irrigation through computational fluid dynamics (CFD) simulations...

BACKGROUND: The Draf III (modified endoscopic Lothrop) procedure has been proposed to extend the endonasal transethmoidal, transfovea ethmoidalis, and transcribriform approach through the back wall of the frontal sinus. The exposure is time-consuming and increases the risk of cerebrospinal fluid leak, and the indications for use are not well described. There are few data quantifying the advantage it conveys over the approach without the Draf III procedure. METHODS: An endoscopic, endonasal transfovea, transcribriform approach was performed in 5 fresh, injected cadaveric heads...

OBJECTIVE: Visualization by Draf I-III endoscopic access to the frontal sinus via drainage pathways is sometimes inadequate. We compare lateral frontal sinus exposures by Draf approaches versus our modification of removing the medial-superior wall of the orbit while preserving the periorbita. METHODS: Twenty cadaveric heads dissected using Draf IIB, III, and modified Draf III with medial and superior orbital decompression (MSOD) underwent thin-cut computed tomography (CT) scanning...

CONCLUSION: Conventional endoscopic sinus surgery (CESS) is useful for frontal mucoceles. A patient with short anterior-posterior distance and bone thickening may need an axillary flap, Draf type IIb, or Draf type III procedure. OBJECTIVE: To present outcomes of frontal mucoceles treated with CESS and predict risk factors for poor outcomes to help define surgical indications. METHODS: A consecutive clinical series was reviewed retrospectively...

OBJECTIVES: Draf IIb approach provides wide, unilateral access to the frontal sinus. This approach can be extended without destruction of the contralateral frontal sinus drainage pathway, performed during Draf III (modified Lothrop) procedure. There is limited data in the literature regarding the use of modified Draf IIb procedures. METHODS: Patients treated with extended Draf IIb procedures in a single center were retrospectively assessed. RESULTS: Ten patients were identified, including 2 cases of osteoma, 1 inverted papilloma, 1 carcinoma, 5 mucoceles, and 1 chronic rhinosinusitis patient...

BACKGROUND: Stenosis of the frontal neo-ostium after Draf III procedure has been associated with inflammatory risk factors. However, the degree to which neo-osteogenesis contributes to postsurgical stenosis of the frontal neo-ostium is unclear. METHODS: Twenty-five patients with chronic frontal sinusitis who underwent Draf III procedure and had been followed for at least 12 months were included. Paranasal sinus computed tomography (CT) scans were performed 7 days and 1 year postoperatively...
