Objectives: To investigate the olfactory fossa depths and lateral lamella lengths of patients with different types of developmental disorders of paranasal sinuses in comparison with normal controls.Study Design: Retrospective, archival, radio-anatomical study. Methods: We included 58 patients with maxillary sinus hypoplasia, 50 patients with frontal sinus hypoplasia/aplasia, 50 patients with sphenoid sinus hypoplasia/aplasia, and 40 normal controls. Reviewing paranasal computerized tomography scans, we noted the olfactory fossa depths and lateral lamella lengths of all the groups and compared between the hypoplasia groups and the control group.Results: Compared with the normal controls, the maxillary hypoplasia group (P < 0.001), frontal hypoplasia/aplasia group (P = 0.004), and sphenoid hypoplasia/aplasia group had significantly deeper olfactory fossa (P = 0.003). The mean lateral lamella lengths in the type 1, type 2, and type 3 hypoplastic maxillary sinus groups were significantly greater compared with that in the control group (P < 0.001). Additionally, the mean lateral lamella lengths in the hypoplastic frontal sinus, aplastic frontal sinus, and hypoplastic sphenoid sinus groups were significantly greater compared with that in the control group (P < 0.001).Conclusion: The patients with pneumatization defects of the maxillary, frontal, and sphenoid sinuses had deeper olfactory fossa and longer lateral lamella related to increased risk of skull base injury during endoscopic sinus surgery.

Nasal septal body is a thickened mucosal area of nasal septum with an unknown certain role. In this study, the authors aimed to investigate the association between the area, length, and width of the nasal septal body with inferior turbinate hypertrophy (ITH) and allergic rhinitis (AR). A total of 106 patients with ITH (54 with AR and 52 without AR), and 49 patients without ITH and AR (control group) were included in this study. Using axial and coronal paranasal computed tomography scans, the area, length, and width of nasal septal body were measured, and the mean values between the groups were compared. Mean area, length, and width of nasal septal body significantly differed among 3 groups (P < 0.001). Septal body area was significantly greater in ITH with AR group, compared to ITH without AR group (P < 0.001) and the control group (P < 0.001). Also, it was significantly greater in ITH without AR group compared to the control group (P < 0.001). Septal body width was significantly greater in ITH with AR group, compared to ITH without AR group (P < 0.001) and the control group (P < 0.001). Also, it was significantly greater in ITH without AR group compared to the control group (P < 0.001). Patients with ITH had a greater nasal septal body area, length, and width, compared to the patients without. Moreover, AR had an additional increasing effect on the area and width of the nasal septal body.

Objective: Although prevention of radial artery thrombosis and cardiac complications after interventions using radial access is well investigated, there is yet no clinical study that completely evaluated access-related complications. However, there is still no consensus on what exact treatment should be used in these patients. In clinical practice, analgesic, anticoagulant, and antiplatelet treatments usually improve symptoms in patients with pain; however, in some patients, complaints may persist and may not respond to these treatments. In these patients, low-risk embolectomy with a small skin incision may be beneficial. Methods: A total of 102 patients with radial artery thrombosis after cardiac catheterization were included in the study between 2016 March and 2018 December. After the patients’ initial evaluation, anticoagulation with enoxaparin or tinzaparin and antiplatelet therapy with acetylsalicylic acid and oral/local analgesic/anti-inflammatory and local anesthetic therapy were administered for 1 month. Patients whose symptoms resolved after medical treatment were followed up as outpatients. Embolectomy was performed in consenting patients who did not respond to the medical treatment. Results: Of 102 patients included in the study, 33 underwent embolectomy, whereas 69 received only medical treatment. None of the patients experienced any complications, morbidity, or mortality in the peroperative period and during the medical treatment. The pretreatment symptom scores of patients who actively use their hands in daily life and profession were significantly higher than the scores of patients who are relatively less active ( P = .013). Pretreatment symptom scores were negatively correlated with age ( r = −0.584); symptom scores increased significantly with the decrease of patient age. No benefit from medical treatment and need for surgery was significantly greater in patients who are younger and use their hands actively in daily life and profession ( P = .028). The decrease in symptom scores after treatment was significantly greater in the surgical group than in the medical group ( P = .003). Conclusion: Radial access should be exercised with care in patients who may develop significant thrombosis-related complaints and it is necessary to decide whether radial access is essential. If patients have ongoing symptoms despite medical treatment, embolectomy can be considered as a treatment option.
