“…Two others are the atelectatic or hypertrophic UP which may originate from pneumatization. [4] Diverse anatomical variations of pneumatized maxillofacial osseous structures have been frequently reported in the medical literature. However, there still is no definite explanation for why pneumatizations occur with such anatomical variation.…”

Objectives: This study aims to investigate the prevalence of uncinate process (UP) pneumatization and also to investigate the association of UP pneumatization with concurrent morphological variations in neighboring structures and the presence of maxillary sinusitis. Patients and Methods:This was a retrospective study where coronal computed tomography scans of 1,500 UPs in 750 patients (483 males, 267 females; mean age 36.3±14.7 years; range 7 to 84 years) were examined to determine the prevalence of UP pneumatization and to assess any concurrent neighboring anatomical structures and the presence of maxillary sinusitis between January 2013 and June 2013.Results: Uncinate process pneumatization was identified in a total of 6.26% of our patients with 1.60% being bilateral, 2.53% on the right only, and 2.13% on the left side only. Other than concurrent occurrences of right maxillary sinus septa (p=0.046), growth of the right ethmoidal bulla (p=0.044) and presence of maxillary sinusitis (right side: p=0.046, left side: p=0.035) were seen. Conclusion:We detected a 6.2% prevalence of UP pneumatization in our study group. An abnormally sized and over-pneumatized UP can cause narrowing of the infundibulum and impaired sinus drainage. Such functional blockage can lead to recurrent maxillary sinusitis, stuffiness, and decreased olfaction.Keywords: Computed tomography; paranasal sinus; pneumatized; sinusitis; uncinate process.

“…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

“…Osteomeatal kompleks, anatomik olmaktan çok fonksiyonel bir yapıdır. Özellikle maksiller, etmoidal ve frontal sinüslerin ventilasyonu ve drenajında anahtar bölge olarak bilinir ve sinüslerin normal fonksiyonlarını sürdürmesinde önemli bir role sahiptir [20][21] . Bu fonksiyonel yapıyı maksiller sinüs ostium'u, hiatus semilunaris, infundibulum, frontal recess, etmoid bulla, unsinat proses, frontal sinüs ostium'u ve orta konka oluşturur 14 .…”

Maxillary sinus is an important anatomical formation that must be taken into account in dental practice, which is adjacent to the oral cavity. The osteomeatal complex is located in the middle meatus and is the site of the sinus ostia. It is suggested that strictures in this area cause inflammatory changes in the sinuses. The absence of inflammatory changes in osteomeatal complex and maxillary sinuses is a vital factor in the success of operations such as sinus lifting operations. In this review, it was aimed to summarize the radiological methods, findings of maxillary sinus pathologies and osteomeatal complex . Key words: Osteometal complex, maxillary sinuses, radiological examination, diagnosis ÖZET Maksiller sinüs oral kaviteye komşuluğu olan diş hekimliği uygulamalarında dikkate alınması gereken önemli bir anatomik oluşumdur. Osteomeatal kompleks ise orta meatusda yer alan ve sinüs ostiumlarının açıldığı yerdir. Bu alandaki darlıkların sinüslerde enflamatuar değişiklere sebep olduğu ileri sürülür. Osteomeatal komplekste ve maksiller sinüslerde enflamatuar değişikliklerin bulunmaması, sinüs lifting operasyonu gibi operasyonların başarısı için hayati bir faktördür. Bu derlemede maksiller sinüs patolojileri ve osteomeatal kompleksi görüntülemek için uygun radyolojik yöntemlerin, bulguların özetlenmesi amaçlandı.
