“…The paranasal sinus region is a large varied and complex fi eld (1), and congenital anomalies and anatomical variation may cause diffi culties during functional endoscopic sinus surgery (2). Certain anatomical variations in this fi eld may lead to chronic sinusitis and mucosal diseases (3).…”

OBJECTIVE: The aim of this study was to evaluate the frequency of anatomical variation in nasal cavity and paranasal sinuses by comparing a unilateral cleft lip and palate (UCLP) group with a non-syndromic control group using cone beam computed tomography (CBCT). SUBJECTS AND METHODS: This study included 24 UCLP patients in the UCLP group and 24 non-syndromic patients in the control group. Coronal CBCT images were taken in all patients and were evaluated for anatomical variation. The measurements obtained in this study were analysed using chi-square and Fisher's exact tests to compare the two groups statistically. RESULTS: In the UCLP group, there were statistically lower frequencies of pterygoid process pneumatisation (p <0.05), higher wing pneumatisation (p < 0.05), and sphenoid sinus over pneumatisation (p < 0.05), and statistically higher frequencies of anterior nasal septal deviation (p < 0.05) compared to the control group. CONCLUSION: A higher incidence of anterior nasal septal deviation was found in UCLP patients compared to the patients in the control group. It is likely that for this reason, UCLP patients might be predisposed to sinusitis. In UCLP patients, the incidence of neurovascular structures in the sphenoid sinus was lower than that in non-syndromic control patients (Tab. 1, Fig. 6, Ref. 33). Text in PDF www.elis.sk.

“…Thus basal lamella of the middle nasal concha represents the surgical posterior limit for an anterior ethmoidectomy. Anatomic variations of ethmoid cells have been reported [7][8][9] whereas anterior, middle and posterior ethmoid cells communications with each other through unusual hole noted in this study such congenital malformation of bony orbit have not been reported in the modern medical literature. Such variable bony orbit anatomy helps in understanding the pathophysiology and spread of sinus disease, as well as performing the most complete ethmoid surgery with the least surgical complications.…”

Background: The thinnest portion of the medial wall of the orbit is Lamina orbitalis ossis ethmoidalis which separates the ethmoidal sinuses from the orbit. Congenital bony malformation of orbit and anatomical variation of ethmoidal sinuses are important in terms of the risk of complication development during endoscopic sinus surgery and to understanding the pathophysiology and spread of sinus disease.Materials and Methods: Accordingly the present study was designed to fi nd out the congenital malformation of medial wall of the orbit in relation to lamina orbitalis ossis ethmoidalis. The study was carried out using 100 dried adult human skulls and twenty six human cadavers irrespective of sex were obtained from the Department of Anatomy - Mayo Institute of Medical Sciences-Barabanki, Department of Anatomy - Melaka Manipal Medical College - Manipal and Department of Anatomy - KMCT Medical College, Manassery - Calicut.Results: In three skulls (2.380%) we noted unilateral unusual hole at the junction of medial wall and roof of orbit with dimensions of 2.3 cm long and 1 cm height in two skulls and another unusual vertical hole at the anterior part of medial wall and roof of orbit with dimensions of 2 cm height and 1 cm width. We also noted few ethmoidal cells extended in to the orbital plate and fovea ethmoidalis of the frontal bone.Conclusion: Congenital defective formation of bony orbit and variable anatomy of paranasal sinuses noted in this study is may be due to the defective formation of Lamina orbitalis ossis ethmoidalis from the lateral part of the nasal capsule near the fronto ethmoidal suture such comprehensive knowledge is necessary to understand the various disorders of this region and to avoid complications during surgical procedures involving this area.DOI: http://dx.doi.org/10.3126/ajms.v6i2.10534Asian Journal of Medical Sciences Vol.6(2) 2015 91-94

“…This result is close to that of Bruner et al [25] which reported a frequency of 10%. Higher frequencies have been found by Ka-Planoglu et al [1] (63.8%), Azila et al [16] (81.2%), Keast et al [14] (94%), Perez-Pinas et al [3] (100%) and Tonaï et al [15] (86.7%). The fact to consider only a hyper-pneumatization of Agger-Nasi cell which is supposed to have a mass effect on the front-nasal mechanism as anatomical variant can explain the deviations observed in the frequencies.…”

“…Our results are comparable to those found out by Perez-Pinas et al [3] (24.5%), Basi et al [12] (21%) and Jones et al [13] (20%). Higher frequencies were found out by Ka-Planoglu et al [1] (30.4%), Keast et al [14] (29%), Tonai et al [15] (28%), and Azila et al [16] (40.8%). However Bolger et al [17] reported a low frequency of 15.7%.…”

Objective: Determine the frequency of the sinonasal mechanical anatomic variants by CT Scan. Patients and method: Six-month retrospective study concerning sinus CT scans in the registers of Teaching Hospitals' Imaging Services of Lomé and Kara (TOGO). It involves patients without distinction of sex, of over 15 years without anomaly that can lead to a modification of the normal anatomical configuration of the paranasal sinuses' cavities. The analysis has been made by only one radiologist. Results: The frequency of mechanical sinonasal anatomic variants stood at 91.87%. The narrowing of the middle nasal turbinate was the variant mostly observed (55.03%), dominated by the deviation of the nasal septum whose frequency was 25.48%. The narrowing of the infundibulum represented 10.80% of population. They were more represented by the Haller cell which displayed a frequency of 3.60%. The variants venturing to narrow the upper nasal turbinate, represented only by extra turbinates, involved 1.02% of the population. The other variants of mechanical sinonasal anatomic variants represented 25.02%. They were dominated by the maxillary sinus septa (11.2%). Our study showed a feminine predominance which is statistically important for Haller cells (p = 0.037) and the ethmoidbulla hypertrophy (p = 0.0036). Conclusion: The anatomic variants of mechanical sinonasal are very frequent in Togo.

Abstract: When performing endoscopic sinus surgery on those with Polynesian ethnicity, there are no specific anatomical variations to take into account.
