Concha bullosa

Background and aim Nasal obstruction is one of the most common reasons for consultation addressed by otolaryngologists. There are anatomical, physiological, and pathological etiologies. Sometimes the treatment can become a challenge for the specialist, so a detailed evaluation of the etiologies must be carried out. The involvement of the nasal vestibular body (NVB) in obstructive symptoms has been described. Therefore, we must be familiar with its anatomy, presentation, and contribution to this symptomatology...

Pneumatized middle turbinate (Concha bullosa) is one of the commonest intranasal anatomical variants. Surgery is the effective method to control symptomatic concha bullosa, however, still no clear definition for the best surgical technique. The aim of our study to assess and compare the short-term outcomes of crushing and lateral laminectomy with and without mucosal preservation in the surgical treatment of symptomatic concha bullosa. Thirty patients who underwent concha bullosa surgery (a total of 42 conchae surgeries) were included in this prospective randomized study...

This study assessed the frequency of accessory maxillary ostium (AMO) in patients with/without sinusitis and its correlation with anatomical variations using cone-beam computed tomography (CBCT). In this cross-sectional study, 244 CBCT scans were evaluated in two groups: with maxillary sinusitis having > 2 mm mucosal thickening and without max sinusitis as a normal group having normal or less than 2 mm mucosa. The CBCT scans of each group were carefully evaluated for the presence/absence of AMO, patency/obstruction of the primary maxillary ostium (PMO), and the presence of anatomical variations of the paranasal sinuses...

The goal of this study is to evaluate the association between sinonasal anatomic variants and RARS. METHODS: A 1:2 retrospective case-control study was conducted using patients presenting to the rhinology clinic from August 2020 to January 2023. A total of 60 patients with RARS were compared to 120 control patients...

INTRODUCTION: Among many anatomical variations of the skull and cervical spine, some may be an underlying cause of a disease, while others remain clinically silent. The estimated individual prevalences of them differ, but given the available data it is impossible to clarify how frequently they coexist with each other. The following study presents an example of seven anomalies, amongst which at least few have manifested clinically in the examined patient. CASE REPORT: A 35 y...

BACKGROUND: Chronic rhinosinusitis (CRS) is a syndrome with multifactorial aetiology. Amongst which, anatomical variations studied by computed tomography of paranasal sinuses (CT PNS) had a high incidence which varied between 64.0% and 99.8%10 . Due to such high incidence, this study is undertaken to assess the various anatomical variations and their significant association in CRS. METHOD: A prospective observational study was conducted in 70 CRS patients and were subjected to CT PNS...

The middle nasal turbinate is an important anatomical formation located on the lateral nasal wall. Concha bullosa can be defined as the presence of an air gap inside the turbinate. It is the most common middle nasal turbinate variation. It is often asymptomatic, but can sometimes cause nasal obstruction. In this study, an asymptomatic patient with concha bullosa within concha bullosa in both middle turbinates, which has not been reported before in the literature, is presented. Laryngoscope, 2024.

BACKGROUND: Different imaging techniques, such as multi-detector computed tomography (MDCT) scan and cone beam computed tomography(CBCT), are used to check the structure of the nose before rhinoplasty. This study aimed to evaluate the accuracy of two imaging techniques, MDCT scan, and CBCT, in diagnosing structural Variations in rhinoplasty for the first time. METHODS: This diagnostic accuracy study was conducted on 64 rhinoplasty candidates who complained of snoring and sleep apnea or had a positive result in the examination with Cottle's maneuver or modified Cottle technique between February 2021 and October 2022 at 15- Khordad Hospital affiliated to Beheshti University of Medical Sciences...

INTRODUCTION: We present a case of a fourteen year old girl who presented with a large intra-nasal mass to the ENT team at a district general hospital in the UK. PRESENTATION OF CASE: The girl presented predominantly with nasal obstruction and some symptoms of allergic rhinitis. Imaging revealed a large lesion abutting the skull base and causing bony remodelling with marked septal deviation. Based both on CT and MRI imaging, the reporting (non-head and neck) radiologist suggested inverted papilloma as a differential diagnosis...

STUDY DESIGN: This PROSPERO-registered systematic review followed the recommendations of the PRISMA guidelines. Search algorithms were constructed for each of the six databases and gray literature. After screening the references (Rayyan® ), the extracted data were meta-analyzed according to a random-effects model...

OBJECTIVES: This retrospective study aims to analyse alveolar and palatal process pneumatisation and their relationships with sinonasal variations using cone-beam computed tomography. MATERIAL AND METHODS: The study included 500 patients aged 18 to 87 years, involving 1000 maxillary sinuses with cone-beam computed tomography scans. We examined the relationship between inferior maxillary pneumatisation and the following anatomic variations: Haller cell, concha bullosa, paradoxical concha, bifid concha, and septal deviation...

Concha bullosa (CB) is not considered to be a disease, but rather a variation of the paranasal sinus. A CB is defined as the presence of an air cell within the turbinate (pneumatization). The main function of CB is to maintain upper respiratory humidity, regulate thermoregulation, and regulate airflow and filtration. It is common for CB to occur in the middle turbinate, while superior and inferior locations appear to be rare. The patient in this case report was presented mainly with nasal obstruction. During examination, a large mass was found in the left nasal cavity, causing a deviated nasal septum to the right...

PURPOSE: To evaluate via CBCT the anatomical variations of the maxillary teeth and associated major anatomical cavities, the maxillary sinus and nasal fossa. MATERIAL AND METHODS: CBCT scans of 221 patients were used to examine maxillary sinus variations, the posterior superior alveolar artery (PSAA) course, nasal septum variations, middle and inferior concha-meatus variations, canalis sinuosus, infraorbital ethmoid cell, infraorbital canal, anterior nasal spina, and nasopalatine canal...

Objectives: Mucous retention cyst (MRC) is a benign and self-limited lesion that can be caused by many risk factors, including anatomical variations of the sinonasal region. This study aims to investigate the relationship between anatomical variations and the presence of MRC. Materials and Methods: In total, 2109 sinonasal cone beam computed tomography images were evaluated for the presence of MRC, and the sinonasal anatomical regions such as the osteomeatal complex (OMC), infundibulum length, ostium height, the diameter of the ostium, the presence of accessory ostium, concha bullosa, and mucosal thickening of the maxillary sinuses...

Concha Bullosa (CB) is a common sinonasal anatomical variant, which commonly extends into the middle turbinate. Generally, patients presenting with CB are asymptomatic and often incidentally diagnosed with a non-contrast computed tomography scan of the paranasal sinuses. In cases of extensive pneumatization, large CB may cause significant signs and symptoms-commonly, headaches, nasal obstruction, and hyposmia. With only a few reported cases of large CB in the literature; we herein, report a rare case of an unusually massive bilateral CB that resulted in complete obstruction of the left nasal cavity and partial obstruction of the right nasal cavity, in addition to a review of relevant literature...

To determine the prevalence of anatomical variations of nasal cavity and paranasal sinuses of patients with chronic rhinosinusitis (CRS) on CT scan imaging. To correlate the Anatomical variations with the extent of CRS. 100 patients attending the ENT outpatient department with clinically diagnosed CRS were selected for study based on inclusion and exclusion criteria. Patients were subjected to CT scan and diagnostic nasal endoscopy. The correlation of anatomical variation with severity of CRS based on radiological score and endoscopic score was observed...

Mucoceles are respiratory epithelium-lined cystic lesions found in the paranasal sinuses. Pyocele occurs when a mucocele becomes infected. Mucoceles develop as a result of obstruction of the normal sinus drainage tract with superadded infection. Inflammatory mediators are secreted, which lead to bone resorption and expansion of the mucocele. Concha bullosa is one of the most common anatomical variations in the nasal cavity. It refers to an air-filled cavity within the middle turbinate. Obstruction of the concha bullosa can rarely lead to the formation of a mucocele which may be secondarily infected forming a mucopyocele...

BACKGROUND: Knowledge of the anatomy and variations of the maxillary sinus is essential for reducing oral surgery complications, such as sinus floor elevation, and increasing surgery success. The CBCT images of 385 patients were examined. MATERIALS AND METHODS: The prevalence, localization, and height of PMO (Primer Maxillary Ostium) and AMO (Accessory Maxillary Ostium) were evaluated with respect to sex, dentition, dental treatment, Schneiderian membrane (SM) thickness, concha bullosa, Haller Cells, and septal deviation...
