“…The reference point for the measurements was at the medial extent of the orbital floor. The average OF height from the nasal floor documented by Harvey et al [ 13 ], Wuttiwongsanon et al [ 14 ], Lee et al [ 15 ] & Lee [ 19 ] was 33.9 ± 3.0, 35.2 ± 3.4, 33.45 ± 2.83 and 33.83 ± 3.4 respectively. All the measurements were relatively constant despite being done in different populations (Table 3 ).…”

“…Harvey et al [ 13 ], Wuttiwongsanon et al [ 14 ], Lee et al [ 15 ] and Lee [ 19 ] conducted studies on Australian and American, Thai, Canadian and Korean populations respectively (Table 2 ). All studies were based on CT PNS that documented the OF height relative to the nasal floor.…”

“…Lee et al [ 15 ] measured CT PNS from 50 subjects with a total of 100 sides, whereas Lee [ 19 ] measured 230 sides from 115 subjects. The two studies showed relative to the OF, the mean height of the sphenoid roof was 12.18 ± 3.20 mm and 12.02 ± 2.93 mm respectively and the mean height of the sphenoid floor was 5.94 ± 2.94 mm and 6.18 ± 2.88 mm respectively.…”

“…In Asians, the distance of OF to the cribriform was longer and the distance of OF to the sphenoid roof was shorter as compared to Caucasians [ 14 ]. All studies showed that OF was below the anterior skull base irrespective of the populations [ 12 – 15 , 19 ] (Table 4 ). Overall, there was no significant height difference between the left and right skull base documented [ 14 , 15 , 19 ].…”

BackgroundThe orbital floor is considered as an important intraoperative reference point in endoscopic sinonasal surgery. The aim of this review is to evaluate its reliability and usefulness as a surgical landmark in endoscopic endonasal surgery.MethodsA literature search was performed on electronic databases, namely PUBMED. The following keywords were used either individually or in combination: orbital floor; maxillary sinus roof; endoscopic skull base surgery; endoscopic sinus surgery. Studies that used orbital floor as a landmark for endoscopic endonasal surgery were included in the analysis. In addition, relevant articles were identified from the references of articles that had been retrieved. The search was conducted over a period of 6 months between 1st June 2017 and 16th December 2017.ResultsOne thousand seven hundred forty-three articles were retrieved from the electronic databases. Only 5 articles that met the review criteria were selected. Five studies of the orbital floor (or the maxillary sinus roof) were reviewed, one was a cadaveric study while another 4 were computed tomographic study of the paranasal sinuses. All studies were of level III evidence and consists of a total number of 948 nostrils. All studies showed the orbital floor was below the anterior skull base irrespective of the populations. The orbital floor serves as a guide for safe entry into posterior ethmoids and sphenoid sinus.ConclusionsThe orbital floor is a reliable and useful surgical landmark in endoscopic endonasal surgery. In revision cases or advanced disease, the normal landmarks can be distorted or absent and the orbital floor serves as a reference point for surgeons to avoid any unintentional injury to the skull base, the internal carotid artery and other critical structures.

Importance: Safe entry into sphenoid sinus is critical in endoscopic sinus and skull base surgery. A number of surgical landmarks have been used to identify the sphenoid sinus ostium during endoscopic endonasal surgery with variable reliability and intraoperative feasibility. Objective: To determine if the posterior wall of the maxillary sinus is a reliable landmark to determine the depth of the sphenoid sinus ostium during anterior to posterior dissection. Design, Setting, and Participants: Prospective study of adult patients undergoing endoscopic sinus surgery between August 2016 and September 2017. Measurements were made intraoperatively between the depth of the posterior maxillary sinus wall and sphenoid sinus ostium. Main Outcomes and Measures: The primary measurement is the distance between the depth of the posterior maxillary sinus wall and sphenoid sinus ostium. Additional data points included age, gender, surgical indication, and primary versus revision endoscopic sinus surgery. Results: Forty-five patients (38% male, 62% female) with an average age of 56 were enrolled, resulting in 88 operated sides. The average distance between the depth of the posterior wall of the maxillary sinus and the sphenoid ostium was 1.5 mm ± 1.4 mm. The most common position of the sphenoid sinus ostium was posterior to the level of the posterior maxillary sinus wall (54%), followed by same level (23%) and anterior (23%). There was no significant difference between different disease states ( P = .75) and between primary and revision cases ( P = .13). Conclusions and Relevance: The posterior wall of the maxillary sinus serves as an adjunctive intraoperative landmark to determine the depth of the sphenoid sinus ostium. While the posterior wall of the maxillary sinus approximates the depth of the sphenoid sinus ostium, the relative position is variable and can be anterior or posterior.
