Introduction: Concha bullosa is the most common variation of the middle turbinate of the paranasal sinuses. When it causes nasal obstruction, osteomeatal unit dysfunction, or rarely chronic infection, surgery is required.   Case Report: We present a fungal infection of concha bullosa, which is a rare indication for surgery of the concha bullosa. A 59-year-old female patient presented with hemif...

BACKGROUND AND PURPOSE The incidence of middle turbinate pneumatization, or concha bullosa, has been well described in the literature. However, to our knowledge, no study has evaluated concha bullosa in relation to nasal septal deviation. We sought to analyze the incidence of concha bullosa and any correlation with nasal septal deviation and paranasal sinus disease. METHODS Three neuroradiolo...

The objective of this study was to determine the prevalence of concha bullosa and nasal septal deviation and their potential relationships to maxillary sinusitis. 883 CT scans taken at Creighton University School of Dentistry from 2005 to 2008 were retrospectively reviewed for the presence of concha bullosa, nasal septal deviation, and maxillary sinusitis. 67.5% of patients exhibited pneumatiza...

We report two unique cases of 50- and 28-year-old Turkish men with coincidence of conchachoanal polyp and mulberry hypertrophy of the inferior concha. We operated on both cases with endoscopic stripping of the polypoid tissue while preserving the periosteum and healthy mucosa of the inferior nasal concha. The polypoid tile of the left inferior nasal concha was resected in the case with mulberry...

BACKGROUND Studies evaluating the mean volumes of nasal cavity and concha are very rare. Since there is little date on the mentioned topic, we aimed to carry out the presented study to obtain a volumetric index showing the relation between the nasal cavity and concha. MATERIAL AND METHODS The volumes of the nasal cavity and concha were measured in 30 males and 30 females (18-40 years old) on ...

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 lamel...

Sinusitis is an important cause of morbidity and one of the major sources of income loss. Anatomical variations of the nose have been reported to predispose to sinusitis. These variations include concha bullosa, nasal septal deviation and oversized bulla. The aim of this study was to determine the proportion and the distribution of concha bullosa in patients with chronic sinusitis and to determ...

Headache due to the pressure of nasal mucosa in the absence of inflammation of the nose and paranasal sinuses is a clinical entity that has gained wide acceptance. Concha bullosa is the most commonly observed anatomical variation of the lateral nasal wall. The case is presented of a 31-year-old female with a history of intermittent frontal headache and bilateral nasal obstruction in whom we fou...

PURPOSE To assess the relationship among the concha bullosa types and sinusitis, ostiomeatal and frontal recess disease. MATERIALS AND METHODS Computed tomography (CT) studies of 76 patients diagnosed with concha bullosa were reviewed retrospectively. All examinations were performed for evaluation of a symptom referable to sinonasal region. Concha bullosa cases were grouped according to the l...

During electrocochleography, that is, ECochG or ECoG, a recording electrode can be placed in the ear canal lateral to the tympanic membrane. We designed a concha electrode to record both sinusoidal waveforms of cochlear microphonics (CMs) and auditory brainstem responses (ABRs). The amplitudes of CM waveforms and Wave I or compound action potentials (CAPs) recorded at the concha were greater th...
