Massive concha bullosa pyocele with orbital extention

Concha bullosa is the most common anatomic variant of the middle turbinate. It remains usually asymptomatic. Pyocele occurs when concha bullosa becomes infected. In the formation of a pyocele, middle turbinate may become expanded and occupy the surrounding structures with local bone destruction. Direct extension of mass from the nose into the orbit may occur, because the orbital contents are separated from the ethmoidal labyrinth only by the thin lamina papyracea. We report a case of concha bullosa pyocele with orbital extension. Orbital involvement is also associated with ocular functional loss. In this case, ocular motion and vision remained normal despite of the presence of orbital extension for 2 years.     

Large concha bullosa mucopyocele replacing the anterior ethmoid sinuses and contiguous with the frontal sinus

Concha bullosa, a pneumatized middle turbinate, is a common anatomic variant found in the paranasal sinuses. When a concha bullosa becomes obstructed, it can form a mucocele and, eventually, a mucopyocele if it becomes secondarily infected. This is a rare phenomenon; only 9 concha bullosa mucopyoceles have been previously reported in the English-language literature. We present the case of a large concha bullosa mucopyocele in a pediatric patient in which the concha bullosa replaced the anterior ethmoid sinuses and was contiguous with the frontal sinus.     

Massive Concha Bullosa with Secondary Maxillary Sinusitis

Concha bullosa is a common anatomic variation of the middle turbinate; however, sinusitis secondary to the concha bullosa is rare. A 52-yr-old woman presented with nasal obstruction and posterior nasal drip. Computed tomography and examination of the nasal cavity revealed septal deviation on the left side, and a massive concha bullosa and maxillary sinusitis on the right side. The lateral lamella of the affected turbinate was removed and the inspissated material was drained. Histopathologic examination of the excised lesion in the concha bullosa revealed bacterial colonies in the mucus plug. We report here on a massive concha bullosa with secondary maxillary sinusitis.     

Concha bullosa. A radiological study and a new classification

ObjectiveA pneumatised middle turbinate is called concha bullosa. It has been classified according to its extension in the coronal plane. We propose the first classification according to the axial extension of pneumatisation of the middle turbinate.Material and methodsBulbous concha bullosa was classified in six categories according to the degree of pneumatisation of the body of the middle turbinate in the axial plane.Results196 CT sinonasal scans were included. 28.06% of patients had concha bullosa, unilateral in 13.26% and bilateral in 14.79%. The most common concha bullosa found was type I, followed by type III, II, IV and V. There were no statistically significant differences by side, between the patients with or without chronic rhinosinusitis without polyps.ConclusionOur results support the hypothesis that concha bullosa is not related to chronic rhinosinusitis. Furthermore, type IV and V cells mean posterior aeration of the middle turbinate. Those variations are rare and posterior, so they can easily pass unnoticed during endoscopic sinus surgery. Our classification is also important as a surgical reference, and it can be easily studied on the preoperative CT scan.     

Concha bullosa surgery and the distribution of human olfactory neuroepithelium

In bullous middle turbinate surgery, controversy exists over which side of the bullous middle turbinate should be removed, as the distribution of human olfactory neuroepithelium is unclear. This study evaluated whether the middle turbinate tissue of patients undergoing endoscopic concha bullosa surgery contains functional olfactory epithelium. This prospective clinical study was conducted in tertiary referable center. It detected 70 conchae bullosa in 48 patients with sinonasal symptoms, who underwent paranasal computed tomography (CT) that showed pneumatization of the middle concha. All samples were obtained under general anesthesia. Three samples were obtained from each bullous middle turbinate: one each from the anterior, medial, and lateral portions. The mucosa from each sample was stained with olfactory marker protein (OMP). In total, 210 middle turbinate samples were taken from 48 patients during endoscopic surgery for conchae bullosa. The patients were 22 females and 26 males. Of the 70 conchae bullosa, OMP-stained nerve tissue was found in the lateral, anterior and medial aspects of 57 (81.4 %), 42 (60.0 %) and 23 (32.8 %) of the bullous middle turbinates, respectively. OMP-stained nerve tissue was found in 122 (58.1 %) of the 210 bullous middle turbinate tissue samples. OMP-stained nerve tissue was found on the lateral surface of the bullous middle turbinate more often than the medial surface. Therefore, during the concha bullosa surgery, OMP-stained nerve tissue found at least in the medial part of concha, suggested that the opening of the medial part of middle concha.     

Concha bullosa pyocele

An aerated middle turbinate is called a concha bullosa (CB), and given the importance of the middle turbinate in nasal physiology, variations that alter the airflow and mucous drainage can cause sinonasal symptoms. A pyocele of the middle turbinate differs from an infected CB because it has the potential to expand and destroy neighbouring tissues like a tumour. We present a concha bullosa pyocele (CBP) that expanded against the lamina papyracea without causing orbital displacement. As pus was discharged whilst performing an endoscopic biopsy to determine whether it was neoplastic, the lateral aspect of the turbinate was excised to complete the procedure.     

Giant concha bullosa containing another concha bullosa inside: unique anatomic variation of the middle turbinate

Detailed knowledge of the anatomical variations of the lateral nasal wall is crucial for both the surgeon who is performing endoscopic sinus surgery and the radiologist who is involved in the preoperative work-up. Preoperative recognition of these variations will avoid possible complications during the surgery. In this report, we present a unique anatomical variant of the middle turbinate, a large concha bullosa inside a giant concha bullosa, which has never been reported before. Furthermore, we comment on the differential diagnosis of the variations of the middle turbinate and on the embryology of the nasal turbinates. This report also supplies additional aspects to rhinologists in the scope of middle turbinate pneumatization.

Isolated turbinitis and pneumatization of the concha inferior in a child

Concha bullosa of the inferior turbinate is an extremely rare anatomic malformation with 11 reports of this condition in the literature. The inferior turbinate is an independent bone originating from the lateral nasal wall. Although inferior concha bullosa is generally asymptomatic and diagnosed incidentally by computed tomography, nasal obstruction, headache, and epiphora are some of the possible symptoms. Isolated turbinitis with no additional paranasal infection is also very rare. Although there is only 1 reported case of pediatric inferior concha bullosa before, this case is the first pneumatized inferior concha with associated isolated turbinitis.     

A massive superior concha bullosa: case report and literature review

The superior turbinate was the most neglected of the turbinates in the past. With the advent of functional endoscopic sinus surgery and coronal computed tomography imaging, considerable attention has been concentrated exclusively on the lateral nasal wall anatomy, including the hidden turbinate, whose symptomatic concha bullosa is extremely rare. Only a very few cases have been reported to date. This seemingly interesting as well as rare case report is concerned with unilateral hyperpneumatization of the superior turbinate, which contacts the septum and leads to headache, associated with bilateral massive concha bullosa of the middle turbinate.     

Concha bullosa of an inferior turbinate

Pneumatization of the inferior turbinate is a rare intranasal anatomic variant. In the English-language world literature, only 10 cases of inferior turbinate concha bullosa have been reported. We present the 11th such case, which we discovered during an evaluation of a patient who had chronic rhinosinusitis with allergic manifestations.     

Wedge Resection of the Middle Turbinate—An Adjunct to Functional Endoscopic Sinus Surgery (FESS)

A simple technique of wedge resection of the anterior part of the middle turbinate allows a better access to the Osteo meatal complex (OMC) during FESS procedure. In post-operative period it facilitates proper ethmoid cavity care, mandatory to the success of the endoscopic sinus surgery. The technique keeps the middle turbinate away from the lateral wall of the nose and helps reducing the synechia formations. It also exteriorises the apparent and occult pneumatised middle turbinate. It is a simple and safe procedure to perform with minimal trauma to the middle turbinate without complications attributable to the technique. During functional endoscopic sinus surgery this technique affords improved exposure to the OMC in patients with high deviated septum, narrow nasal vault, a large concha bullosa and paradoxical turbinate.     

Is there a relationship between middle concha bullosa and ethmoid roof asymmetry?

IntroductionThe middle turbinate and ethmoid roof are intranasal structures and may have many anatomical variations. These structures, which serve as anatomical markers during functional sinus surgery, are important for preventing complications and performing a proper surgery. Knowledge of anatomical variations will increase surgical success and reduce complications.ObjectiveWe aimed to investigate the presence of asymmetry in the ethmoidal roof and anatomical variation in patients with and without concha bullosa.MethodsIn this study, the files of patients who underwent paranasal computed tomography between 2012 and 2018 were analyzed retrospectively. The patients were divided into two groups, as patients with and without concha bullosa. Differences between the two groups in terms of age, gender, septum deviation, ethmoid artery dehiscence, ethmoid roof asymmetry were examined.ResultsThe 369 patients included in our study were divided into two groups; those with concha bullosa and those without concha bullosa. The mean age of the patients with concha bullosa was 36.1 ± 13.4 (min–max: 12–74) and the mean age of patients without concha bullosa was 37.5 ± 14.3 (min–max: 10–81). The ethmoid roof depths were compared between the two groups and a significant difference was observed (p < 0.001). The ethmoid roof depth was higher in the group with concha bullosa (p < 0.001).ConclusionThe results of our study indicate that the ethmoidal roof tends to be higher in patients with middle concha bullosa.     

Concha bullosa: reducing middle meatal adhesions by preserving the lateral mucosa as a posterior pedicle flap

BACKGROUND: Concha bullosa, an extensively pneumatized middle turbinate, may obstruct the paranasal sinuses. Messerklinger's partial lateral turbinectomy is commonly used to debulk the concha bullosa, leaving a raw surface with the potential for adhesions. MATERIALS AND METHODS: A modified technique of partial lateral turbinectomy is described. A posterior pedicled mucosal flap covers the inferior raw surface of the medial lamella of the middle turbinate. Three-month follow up of a consecutive series is compared with concurrent controls. RESULTS: Two (7 per cent) of 28 posterior pedicled flap and four (21 per cent) of 19 traditional partial lateral turbinectomies developed mild middle meatal adhesions (p = 0.011). Posterior pedicled flap reduced the need for post-operative cleaning of the middle meatus. CONCLUSION: The posterior pedicled mucosal flap is a simple modification to partial lateral turbinectomy that covers the raw surface facing the lateral nasal wall, significantly reducing adhesions and speeding recovery.     

A unique case of multiple sites of pneumatization of the sinonasal bony framework in a pediatric patient

Anatomic variations of the sinonasal bony framework in the pediatric population are quite common. In children with such variations, however, bony pneumatization is uncommon. Moreover, pneumatization of the inferior turbinate in children is extremely rare; to the best of our knowledge, only 3 cases have been previously reported in the literature-none of which involved additional pneumatization variations of the sinonasal skeleton. Herein we present a new pediatric case that was unique in that an inferior concha bullosa coexisted with rarely seen pneumatized anatomic structures.     

Infected inferior turbinate pneumatization

With the widespread utilization of endoscopic nasal surgery, the interest in nasal structures has increased. Inferior turbinate pneumatization is among the most rare causes of nasal obstruction. In the current literature, there are only ten reported cases of inferior turbinate pneumatization. A 52-year-old male patient presented with nasal obstruction, purulent nasal discharge, facial pain and headache. Anterior rhinoscopic examination showed bilateral middle and inferior turbinate hypertrophy and edema of the nasal mucosa. Computed tomography (CT) revealed bilateral frontal, anterior and posterior ethmoidal and maxillary sinusitis with bilateral concha media bullosa and right infected inferior turbinate pneumatization. In this report, infection of this rare anatomical abnormality is presented for the first time and documented with acoustic rhinometry, CT and peroperative photography.     

Bardet–Biedl syndrome and a large concha bullosa pyocele

Bardet–Biedl syndrome is a rare disease involving rode cone dystrophy, polydactyly, obesity, learning disabilities, hypogonadism and renal anomalies, symptoms caused by immotile cilia dysfunction. We report the first case of this syndrome in a teenager with an endonasal mass secondary to pyocele of a concha bullosa. The patient was treated successfully with endoscopic sinus surgery. Nasal obstruction secondary to a middle turbinate pyocele in Bardet–Biedl syndrome has not been described before. The pediatrician and the rhinologist should take this entity into consideration when investigating patients with Bardet–Biedl syndrome and sinonasal symptoms.

The relationship between the concha bullosa,nasal septal deviation and sinusitis

OBJECTIVES: To evaluate the possible relationship between concha bullosa, nasal septal deviation and sinusitis. PATIENTS AND METHODS: Paranasal sinus computed tomography scans of patients suffering from rhinosinusitis were examined. Fifty-four patients with concha bullosa were included in the study. The relationship between concha bullosa, nasal septal deviation and sinusitis was investigated. RESULTS: A statistically significant relationship between unilateral concha bullosa and nasal septal deviation was found (p < 0.01). The relationships of unilateral and bilateral concha bullosa with sinusitis, and bilateral concha bullosa with nasal septal deviation were not statistically significant (p > 0.05). CONCLUSION: In order to define the relation between the concha bullosa, nasal septal deviation and sinusitis, more detailed investigations are needed.     

Nonsurgical versus endoscopic sinonasal surgery for rhinogenic headache

Headaches of sinonasal origin have been described lately. Terms such as middle turbinate syndrome have been used to describe this entity. The true incidence of this headache is unknown. A concha bullosa or a hypertrophied middle turbinate have been associated with these cases. Mucosal contact between the middle turbinate and the nasal septum or the lateral wall of the nose have been attributed as the cause of referred pain in the face. We present data on 23 individuals with refractory primary headache in the absence of any significant sinus symptoms. The duration of the symptoms of these individuals ranged between 4 and 13 years with a mean of 7.2 years. Fifteen patients agreed to undergo surgery, whereas eight refused surgery. After a mean of 23 months of follow-up, all those who did not have surgery continued to have pain that required excessive medications, whereas 60% of those who had surgery reported marked relief of their headaches. Those who had symptoms for less than 7 years had a greater chance of success (OR = 2). Sinonasal surgery seems to be helpful in alleviating primary headaches, especially in individuals whose duration of symptoms is less than 7 years.
