A few studies involve a sufficient number of cases for a statistically satisfactory data analysis, as compleo anatomical variants present a very low incidence. In older cokplejo on average 9 years of age septum deviation tends to be more pronounced Deviated nasal septum was the most common anatomical variation encountered in our study followed by concha bullosa and paradoxically bent middle turbinate.
Int J Pediatr Otorhinolaryngol ; Computed tomography studies of patients evaluated for clinical suspicion of sinusopathy were reviewed.
Concha bullosa is one of the most frequently found anatomical variants 22, Anatomic variation in pediatric chronic sinusitis: Comparison of anatomical variants prevalences in the symptomatic and asymptomatic groups has showed no significant difference Table 1. Earwaker 16in a study of cases, have described variants of the uncinate process in detail, classifying them in association with other variants of t h e ostiomeatal c o mp lex and subdividing them differently from the present study.
CT imaging requirements for endoscopic surgery. Anatomic variations of the paranasal sinuses: Ann Otol Rhinol Laryngol ; The first most anterior portion of the complex includes structures surrounding the frontal recess; the second one corresponds to the structures including the maxillary sinus and middle meatus; and the third and most posterior portion includes the structures surrounding the sphenoethmoidal recess.
Functional endoscopic approach to inflammatory sinus disease: The middle turbinate may be paradoxically curved i. Uncinate Process of the Ethmoid Bone We observed that the uncinate process may be deviated or pneumatized.
Prevalence of incidental abnormalities on computed tomography scans of the paranasal sinuses. In all of the cases, bone algorithm was utilized for documentation, and soft tissues window was utilized in some selected cases.

Tonai A, Baba S. Agger nasi cell and Haller cell were seen in one case each. The uncinate process The most common anatomical variants of the uncinate process are represented by insertion into an unusual topography and pneumatization.

oateomeatal CT examination for endoscopic sinus surgery Auris Nasus Larynx, 26, pp. Accepted after revision December 14, Rev Bras Otorrinolaringol ;64 Supl 2: Notwithstanding, a consensus on this matter has not been reached yet but many recent studies have contributed with new information. It has also been suggested as a predisposing factor for impaired ventilation of the anterior group of sinuses and frontal sinus. This is again very less as compared to that reported by Kayalioglu et al.
Paranasal sinus bony anatomic variations and mucosal abnormalities: Thank you very much for your vote! Nasal Septal Deviation Nasal septum is fundamental in the development of the nose and paranasal sinuses. A positive relation between the cell size and the presence of soteomeatal sinus disease has been described by Liu et al.
The middle concha bullosa is a result of pneumatization of the osseous plate due to ethmoidal extention Figures 2 and 3.
These cells were the least observed in our study i. Find articles by Saurabh Kumar.
Uncinate process insertion into other structures may result in a blind-end obstruction. Anatomic variations of surgical importance in ethmoid labyrinth and sphenoid sinus. Other pneumatized structures compljo Prevalence of incidental paranasal sinus opacification in pediatric patients: J Comput Assist Tomogr.
Tonai A, Baba S. It is important to note that the degree of pneumatization found in the population studied by Tonai and Baba 1 was low, which they attribute possibly to a racial factor the study has been developed in Japan.

CT examination for endoscopic sinus surgery. Distribution of anatomical variations in study subjects. The purpose of these investigations is to determine oteomeatal mucosal abnormalities and bony anatomic variations of paranasal sinus and assess the possible pathogenicity of these findings in patients undergoing evaluation for sinusitis.
Findings of several studies on the theme are summarized in Tables 1 to 6. Among the variants of the uncinate process insertion which were found in 10 cases, complejjo 3.
