Concha bullosa (CB) manifests as a commonly encountered anatomical variant within the middle turbinate; nevertheless, the incidence of sinusitis attributable to CB is notably uncommon. This case represents chronic rhinosinusitis associated with an unusually massive bilateral CB reaching the floor of the nasal cavity which was treated surgically by performing functional endoscopic sinus surgery and partial middle turbinectomy. This case report aims to contribute to the existing knowledge in the field of otolaryngology by elucidating the surgical options associated with massive middle turbinate CB and ultimately improving the care provided by otolaryngology surgeons for patients with similar conditions.

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. This study aimed to highlight the importance of NVB in the role of nasal obstruction and know the impact that it adds to the symptoms of patients through a validated instrument on their quality of life. Material and methods A retrospective, descriptive, and analytical study was conducted on 113 patients with nasal obstruction who attended the outpatient clinic of the Otolaryngology and Head and Neck Surgery Service in a tertiary-level hospital in Monterrey, Mexico from January 2021 to January 2023. The Nasal Obstruction Symptom Evaluation (NOSE) scale was applied to assess the impact of this symptom on the quality of life of the subjects. The causes involved in the obstructive symptoms were identified by physical examination, including NVB. Two groups were made as follows: with the presence of the NVB and with the absence of the NVB, and the means of the NOSE scale were compared. Results A total of 113 patients were included, 59 male patients (52.20%) and 54 female patients (47.80%). The presence of NBV was found in 72 patients (63.70%). Other causes of nasal obstruction were found in 35 patients (31%), with chronic rhinitis being the most frequent in 27 subjects (23.90%). The mean NOSE scale score was higher in the group with the presence of the NVB than in the group with the absence of the NVB (p<0.05). The primary outcome of this study was to know the prevalence of NVB in the Hispanic population with nasal obstruction who attends the otolaryngology clinic. The secondary outcome was to know the relationship between the presence of NVB and the NOSE scores. Conclusion In this study, we observed that NVB is frequently present in patients with nasal obstruction in northeastern Mexico. There is an association between the presence of NVB and higher scores on the NOSE scale. New research will be needed to assess the effectiveness of NVB surgery in improving nasal obstruction and to determine the impact of NVB on nasal obstruction in isolation.

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. Patients were allocated consecutively and equally into 3 groups: Group A (lateral laminectomy without mucosal preservation, n = 10), Group B (lateral laminectomy with mucosal preservation, n = 10) and Group C (Crushing, n = 10). Patients underwent the preoperative and postoperative visual analogue score (VAS) for nasal obstruction and headache, sinonasal outcome test-22 (SNOT-22) and olfactory detection test. All patients were arranged to postoperative reevaluation for 3 months. All groups showed strong significant improvement in VAS results, SNOT-22 and smell test between preoperative and postoperative scores (P < 0.001). There was a significant difference between the three groups only upon comparing lateral laminectomy groups with crushing group. No significant differences were detected between group A and B regarding all the evaluated variables. According to our results, lateral laminectomy was more advantageous than crushing in surgical management of concha bullosa. Moreover, lateral laminectomy without mucosal preservation was as effective as lateral laminectomy with mucosal preservation and there is no detectable difference between both techniques.

OBJECTIVE: Prior studies evaluating the role of sinonasal anatomic variants with recurrent acute rhinosinusitis (RARS) are limited by inconsistent results. 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. RARS was diagnosed based on the International Consensus Statement on Allergy and Rhinology criteria of four or more independent episodes of acute rhinosinusitis per year with at least one episode documented by objective findings, with complete resolution of the infection in-between episodes. Sinonasal anatomic variants included nasal septal deviation (NSD), concha bullosa (CB), infraorbital (Haller) cells, nasal septal spur in the middle meatus, and frontal sinus cells (supra-agger, supra-agger frontal, and suprabullar frontal cells).
RESULTS: Age was similar in RARS and control patients (47.4 ± 16.5 vs. 49.3 ± 14.5, p = 0.432). Both the RARS group and control group were more likely to be female (78.3% vs. 77.5%, p = 0.899). There was no significant association between NSD and RARS compared to the control group (OR = 0.97, p = 0.916), and no significant association between any of the anatomic variants and RARS [infraorbital cells (OR = 0.64, p = 0.167), CB (OR = 0.84, p = 0.596), spur in the middle meatus (OR = 1.28, p = 0.514), supra-agger (OR = 0.88, p = 0.708), supra-agger frontal cells (OR = 0.97, p = 0.939), or suprabullar frontal cells (OR = 1.13, p = 0.766)].
CONCLUSIONS: Our findings suggest no association between nasal septal deviation or any of the anatomic variants studied and RARS.

BACKGROUND: 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.
METHODS: A 35 y.o. Polish woman who suffered from chronic sinusitis was subjected to a computed tomography scan. Mild thickening of the anterior ethmoidal cells\' mucosa, bilateral concha bullosa, paradoxical right middle turbinate, bilateral uncinate process pneumatization and arrested pneumatization of sphenoid sinus were found and addressed in context of the reported symptoms. Simultaneously other, clinically silent anatomical anomalies, were found - namely ossification of the anterior petroclinoid ligament, incomplete medial basal canal and bilateral arcuate foramen.
CONCLUSIONS: To the best knowledge of the authors, this case report is the first to present such a coexistence of this many various anatomical anomalies, among which some played a crucial part in the chronic sinusitis experienced by the patient. Concurrence of multiple variations in the same anatomical area or functional unit may exacerbate clinical presentation of a patient. Identifying a single anomaly ought to warrant a thorough investigation into any other potentially existing variants.

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.

UNASSIGNED: 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.
UNASSIGNED: 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. Intra-operative exploration in fact revealed a very large left middle turbinate mucocele extending to the left frontal sinus. The mass was excised endoscopically without complications.
UNASSIGNED: Although concha bullosa of the middle turbinate of the nose are common, development of a mucocele within them is far less common and for such a mucocele to develop to this size in a child is extremely rare. The egg shell lining of the lesion can be a tell-tale sign of their aetiology when taken alongside other radiological factors. This case highlights challenges in radiological diagnosis of intra-nasal masses in children, which can lead to delays and increased anxiety.
UNASSIGNED: When assessing nasal masses in children it is important to keep a wide differential due to the challenges of diagnosis. A close conversation should be had with local head and neck radiologists and, of course, where there is a unilateral nasal mass tissue sampling is essential and may be taken as part of a full excision where clinically indicated.

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. For this patient, surgery was the last resort. Either perioperative or postoperative complications were observed, and the quality of life of patients improved after surgery.

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.

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. The mucocele of the middle turbinate may present as an uncommon cause of nasal obstruction, headache, and other nasal or ocular symptoms, which, if correctly diagnosed, can be completely reversed by endoscopic surgery.
