Measurement of transepithelial potential difference (PD) on the nasal mucosa has been proposed to test for defective ion transport in cystic fibrosis (CF), and its possible correction after gene therapy or other treatments. The "classical" method records nasal PD under the inferior turbinate, with the disadvantage that the tip of the electrode is not seen by the operator. We have developed a pu...

OBJECTIVE To determine the frequency and clinical relevance of unanticipated histopathologic results in routine sinonasal surgery and evaluate the necessity for histologic processing of nasal septal cartilage, bone, and inferior turbinate specimens. STUDY DESIGN Case series with chart review. SETTING Tertiary care academic medical center. SUBJECTS AND METHODS A retrospective review of sur...

INTRODUCTION Numerous surgical techniques for inferior turbinate hypertrophy (ITH) have been reported, each with advantages and disadvantages. Submucosal turbinoplasty with removal of the bony component of the inferior turbinate (IT) is an excellent procedure to expand the nasal cavity. However, this procedure requires a large incision to remove the inferior turbinate bone (ITB) and is associat...

Background: In recent years, many techniques for endoscopic closure of CSF leaks have been described and almost completely replaced the more traumatic transcranial and extracranial procedures. Aim of work: To evaluate endoscopic endonasal multilayer repair of CSF rhinorrhea of anterior and middle cranial fossae utilizing the vascularized middle turbinate rotational flap. Patients and methods: T...

BACKGROUND Atrophic rhinitis is a widely prevalent infectious disease of swine caused by Bordetella bronchiseptica and Pasteurella multocida. The course of the disease is considered to be different depending on the principal aetiological agents distinguishing B. bronchiseptica induced non-progressive and toxigenic P. multocida produced progressive forms. In order to compare the pathological eve...

Osteomas are benign, slow growing bone tumors often seen in paranasal sinuses, mostly in the frontal sinus, whereas they are rare in the nasal cavity. Inferior turbinate osteoma is extremely rare and our case is the third reported in the literature to date. Symptoms vary depending on the location, size and spreading and nasal obstruction is the most common symptom. Treatment of osteomas is surg...

Pneumatization of the intranasal turbinates or concha bullosa is an anatomic variation of the lateral nasal wall. Concha bullosa is defined as the presence of air cells in turbinates. It can be best diagnosed with paranasal sinus computed tomography. Concha bullosa is a possible etiologic factor for recurrent sinusitis due to its negative effect on paranasal sinus ventilation and mucociliary cl...
