“…Bilateral pneumatization was observed in 12.5% of the patients. This prevalence falls among the range reported in the literature in other ethnic populations of 6-47.2% (Table 5) [12,13,16,21,[24][25][26][27][28]. Two studies have shown an association between pneumatization of ACP with protrusion of the ON into the aired space [12,25] and 1 of them with dehiscence of the bony canal of the ON [12].…”

Introduction: Pneumatization of the sphenoid sinus (SS) varies widely among different ethnic groups. Information regarding the prevalence and significance of SS variants among Hispanic groups is limited. This study aims to describe and analyze pneumatization and septation patterns of the SS in a Hispanic population. Methods: A total of 160 paranasal sinus computed tomographies were reviewed by a head and neck-specialized radiologist and 2 otolaryngologists. Results: The postsellar and sellar types were the most frequent patterns of pneumatization observed, with a prevalence of 52.5 and 40%, respectively. Accessory septations were present in 59.4% of the patients. Septa were inserting over the internal carotid artery (ICA) in 43.8% and over the optic nerve in 17.5% of the population. No significant association (p > 0.05) was observed when comparing the different accessory septation patterns among the types of the SS. The frequency of septa inserting on the ICA was significantly higher in postsellar types (p < 0.001). Pneumatization of the anterior clinoid process, pterygoid processes, and greater wing was present in 20, 17.5, and 45.9% of the sinuses, respectively. Onodi cells were encountered in 40% of the sinuses. There were no significant differences in any of the pneumatization and septation variables when compared by gender and age (p > 0.05). Discussion/Conclusion: Differences regarding anatomical variants and septations of the SS were observed in our study when compared with findings reported in other ethnic groups. Preoperative assessment of the anatomical variants of the SS in Mexican patients is imperative to select the most optimal surgical approach and prevent iatrogenic injuries to related neurovascular structures.

“…A total of 26% patients had bilateral sphenoethmoidal cells. These rates are higher than 14, 18, and 23% reported in Malaysian, Egyptian, and Turkish populations, respectively (Table 5) [12,13,24]. Tawfik et al [12] found a significant association between the presence of OC and ON protrusion and dehiscence.…”

“…The sphenoid sinus can be seen in computed tomography (CT) as early as 2 years old age and is usually fully grown by the age of 14 [23]. [30] retrospectively investigated the interconnection between sphenoid sinus, carotid canal, and visual canal using paranasal sinus computed tomography (PNSCT) of 300 patients with 159 male and 141 female. In his work, ICA canal protrusion was 23.9-32.1% in males and 35.5-36.2% in females.…”

For the period of 2019, magnetic resonance imaging of the head of patients aged 20–71 years was performed. The majority of males have mezocran the shape of the skull, in contrast to females. There was no universal type of pneumatization for both sexes. In young men, the sellar type prevails, but at the age of 60, this type is 2 times less common and there are no protrusions of the channels of the optic nerves and internal carotid arteries. However, only the protrusion of the internal carotid artery channel is more common in women over 60 years of age than in men. In men, there were no cases of canal protrusion, and 49% of young women had a depression in the wall of the sphenoid sinus. In men under the age of 60, the protrusion of the optic nerve channels and internal carotid arteries occurs in approximately the same way as in women over 80 years of age. Due to the variability of the anatomical configuration of the sphenoid sinuses, the impact on access to the cell through the nose can be serious. The surgeon must be aware of these results before surgery in order to reach the cell safely and effectively.

“…Anatomic predispositions to ICAI include patients with incomplete bony encasement of the internal carotid artery (ICA). 1 ICAIs have been reported in functional endoscopic sinus surgery 2 as well as in more extended skull base operations. 3 Although ICAI occurs in as few as 0.2% of cases, 4, 5 the probability of a high-volume surgeon experiencing at least 1 ICAI approach is a near certainty over a sufficiently long career.…”

Background: Internal carotid artery injury (ICAI) is a rare, life-threatening complication of endoscopic endonasal approaches (EEAs). High-fidelity simulation methods exist, but optimization of the training cohort, training paradigm, and costs of simulation training remain unknown.Methods: Using our previously validated, high-fidelity, perfused-cadaver model, participants a empted to manage a simulated ICAI. A er a brief instructional video and coaching, the simulation was repeated. Training success was defined as successful ICAI control on the second a empt a er failure on the initial a empt. Marginal costs were measured.Results: Seventy-two surgeons participated in the standardized simulation, which lasted ࣘ15 minutes. The marginal cost of simulation was $275.00 per surgeon. A total of 44.4% (n = 32) succeeded on the first a empt before training (previously proficient); 44.4% (n = 32) failed the first a empt, but succeeded a er training (training successes); and 11.1% (n = 8) failed both a empts. The cost per training success was $618.75. Forty-two surgeons had never treated an ICAI, with 24 becoming training successes (57.1% overall, 82.8% when excluding previously proficient surgeons). Twenty-nine had experienced a real or simulated ICAI, with 8 (27.6% overall, 72.7% excluding previously proficient surgeons) becoming training successes. The cost per training success was lowest in the ICAI-naive group ($481.25) and highest among surgeons with simulated and real ICAI experience ($1650). Conclusions:Surgeons can be trained to manage ICAI in a single, brief, low-cost session. Although all groups improved, training an ICAI-naive or resident cohort may maximize training results. A perfused-cadaver model is a reproducible, realistic, and low-cost method for training surgeons to manage life-threatening ICAI during an EEA. C 2019 ARS-AAOA, LLC.
