Management of the frontal sinus places great demands on the otolaryngologist. Given that the fronto-ethmoidal region is susceptible to recurrent inflammation, scarring, and stenosis, maintaining long-term patency of the frontal sinus is a difficult challenge. Oral and topical anti-inflammatory therapy, post-operative stenting, and 'home-brew' drug elution have been used for the treatment of the frontal sinus with mixed success. Recently an implant has been approved for post-operative placement into the frontal recess...

This letter is a commentary on the article titled "Evaluation of variations in sinonasal region with computed tomography", published in the January 2016 issue of World Journal of Radiology. The authors definition of the secondary middle turbinate is incorrect. The authors stated that the secondary middle turbinate is an accessory turbinate that is seen between the superior and middle turbinates. It should originate from the middle meatus posterosuperior to the ethmoid infundibulum.

OBJECTIVES: To assess the reliability of clinical staging with CT and MRI in sinonasal cancers. METHODS: We conducted a retrospective review of patients who underwent surgery for a sinonasal cancer. The 7(th) edition of the TNM classification was used to establish tumor staging. Standardized preoperative CT/MRI staging was compared with the pathological staging based on specimens obtained during surgery from each subsite within and around the tumor. RESULTS: We analyzed data from 68 patients between January 2010 and December 2014...

Soo Hyang Lee, Mun Geun Koo, Eun Taek Kang
BACKGROUND: Septal extension grafts are an effective means of extending nasal length in patients with a short nose. However, such grafts can be challenging in patients who only have small quantities of weak septal cartilage, such as some East Asian patients. We developed a rhinoplasty technique using ethmoid bone to create a cartilage-bone complex to overcome this issue, allowing adequate nasal lengthening. METHODS: Sixty-four women with short noses and inadequate septal cartilage determined by preoperative computed tomography underwent septal extension grafting with a cartilage-bone complex between January 2009 and December 2014...

BACKGROUND: Enzootic nasal tumor virus (ENTV-1) is an ovine betaretrovirus that has been linked to enzootic nasal adenocarcinoma (ENA), a contagious tumor of the ethmoid turbinates of sheep. Transmission experiments performed using virus isolated from cell free nasal tumor homogenates suggest that ENTV-1 is the causative agent of ENA; however, this etiological relationship has not been conclusively proven due to the fact that the virus cannot be propagated in vitro nor is there an infectious molecular clone of the virus...

A 50-year-old man, with no previous history of epistaxis, was hospitalized at our facility for left recurrent posterior epistaxis. The patient underwent surgical treatment three times and only the operator's experience and radiological support (cranial angiography) allowed us to control the epistaxis and stop the bleeding. The difficult bleeding management and control was attributed to an abnormal course of the left posterior ethmoidal artery. When bleeding seems to come from the roof of the nasal cavity, it is important to identify the ethmoid arteries always bearing in mind the possible existence of anomalous courses...

The aim of this study was to clarify the morphological patterns and proportions of the components of the nasal septum. Anatomical examinations were performed on 70 nasal septums of embalmed Korean adult cadavers. The septal deviation was checked before cutting the nasal cavity midsagittally with the aid of a laryngoscope. The shape of each component of the nasal septum was identified, and photographs were taken from a midline sagittal view. A line was drawn on each photograph between the septal components, and then the area of each septal component was measured using software...

Osteomas are the most common benign tumors of the paranasal sinuses. They are usually localized in the frontal sinus. Giant osteomas of the frontal sinuses are very rare but readily extend into the intraorbital or intracranial cavity, causing serious complications. This is a report of a 14 year-old boy with a bulging in frontal area and asymptomatic giant osteoma of the frontal sinuses. He had a history of minor trauma that had a bulging after 3 months. However, he referred to a plastic surgeon after 15 months...

Philippe F Bowles, Satish Agrawal, Mahmoud A Salam
Balloon dilatation of sinus ostia (sinuplasty) was introduced in 2005 as a treatment for Chronic Rhinosinusitis (CRS).(1) It has been described as a 'transition space' tool for the ethmoidal infundibulum and frontal recess.(1) It can been used as a lone procedure or in combination with functional endoscopic sinus surgery (FESS) as a "hybrid" technique. Balloon sinuplasty applies the Seldinger technique to cannulate and dilate stenosed or occluded sinus ostia re-establishing drainage pathways and ventilation...

CONCLUSION: The study demonstrated considerable inter-observer variation in certain surgically important structures. This would indicate the significance for consultation when evaluating sinus CT scans of CRS patients for planned advanced sinus surgery. OBJECTIVES: After the failure of medical treatment of chronic rhinosinusitis (CRS), the need for surgery and the pre-operative planning of safe surgery is based on computed tomography (CT) findings. The aim of this prospective study was to compare inter-observer agreement of anatomical and surgical structures of sinus CT scans...

An otherwise healthy 34-year-old man was referred to our ear, nose and throat (ENT) clinic for a bilateral maxillary radiologic opacity. This condition was accidentally discovered with a panoramic radiography performed during a follow-up visit after a bilateral endodontic treatment. The patient did not report any specific sinonasal symptom such as purulent nasal discharge, loss of smell and cough, apart from an unspecific sinus pressure. The CT scans showed a bilateral inflammatory process into the maxillary-ethmoidal sinuses and an iron-like density within the maxillary sinuses, while nasal endoscopy showed purulent discharge in the ostiomeatal complex...

BACKGROUND: Recent improvements in image quality have contributed to an increasing number of incidental findings (IF). Also called as "incidentalomas", this generic term refers to an entity discovered unexpectedly on an imaging examination performed for other reason. Commonly, normal variants, minor developmental anomalies and imaging artifacts are described as potential pathology. Some IF were reported in Magnetic Resonance Imaging (MRI) exam of temporomandibular joint (TMJ), including IF in the brain, maxillary sinus, ethmoidal cells, mastoid cells, salivary glands, muscles...
