BACKGROUND: Inadvertent lateralization of the middle turbinate (MT) after endoscopic sinus surgery (ESS) is cited as a common complication that results in both outflow tract obstruction and recurrent symptoms. In endoscopic endonasal skull-base surgery, the MT is frequently lateralized during the parasagittal approach. Little is known about whether this strategy has unintended consequences on the adjacent paranasal sinuses. Intentional lateralization vs surgical resection of the MT were compared for radiographic evidence of sinus obstruction in this patient population...

BACKGROUND: Chronic rhinosinusitis (CRS) is a common yet under-recognised chronic inflammatory disease of the nose and paranasal sinuses that is classified according to the presence (CRSwNP) or absence (CRSsNP) of nasal polyps. METHODS: This paper reports the methodology and descriptive results of the Global Allergy and Asthma European Network (GALEN) rhinosinusitis cohort. We established a large CRS cohort within the GALEN consortium (European FP6 research initiative) to identify inflammatory endotypes, the natural disease course, and its impact on health-related quality of life (HRQoL)...

Cerebrospinal fluid (CSF) leaks are extracranial egress of CSF into the adjacent paranasal sinus or tympanomastoid cavity due to an osteodural defect involving skull base. It can be due to a multitude of causes including accidental or iatrogenic trauma, congenital malformations and spontaneous leaks. Accurate localization of the site of the leak, underlying causes and appropriate therapy is necessary to avoid associated complications. In this paper relevant anatomy, clinical diagnosis, imaging modalities and associated findings are discussed along with a brief mention about management...

Endometrial carcinoma is the fourth most common cancer affecting women in the UK. Its most frequent sites of spread are to the pelvic and para-aortic lymph nodes, vagina and peritoneum. We report a case of a 63-year-old woman with known endometrial cancer who presented with left facial swelling and eye displacement. Investigations revealed an expansile soft-tissue density mass arising within the bone, centred on the left zygoma, with exophytic extension into the left maxillary antrum, infratemporal fossa and inferiorly into the orbit...

Facial pain is not an uncommon reason for referral to an otolaryngologist, frequently misdiagnosed as sinusitis by primary care professional. However, many of these 'sinus headache' patients do not have concomitant clinical symptoms suggestive of sinus infection such as purulent discharge or pyrexia [1]. Most actually suffer from non-sinugenic facial pain conditions such as atypical migraine or tension headache [2]. This article is protected by copyright. All rights reserved.

PURPOSE: We aimed to investigate the medial and inferior localization of orbit in patients with maxillary sinus hypoplasia using paranasal computerized tomography. METHODS: We included 76 patients who had a hypoplastic maxillary sinus at least on one side, and 76 patients with normal maxillary sinuses (control group). To assess the localization of orbit, we measured the distances from middle meatal antrostomy point to medial border of orbital medial wall and to the lower border of orbital floor in all patients...

Sinunasale Erkrankungen zählen mit zu den häufigsten chronischen Erkrankungen und führen zu einer erheblichen Störung der Lebensqualität, ein komorbides Asthma ist häufig. Trotz leitliniengerechter Therapie ist anzunehmen, dass mind. 20% der Patienten ihre Erkrankungssymptome nicht adäquat kontrollieren können. Neben den etablierten chirurgischen und konservativen Therapieoptionen finden sich nun vielversprechende Therapieansätze, die bspw. mittels therapeutischer Antikörper mechanistisch gezielt in die Pathophysiologie der Erkrankungen eingreifen können...

BACKGROUND: Olfactory training (OT) helps many patients with olfactory loss, but unfortunately it is ineffective for a significant number of patients. Budesonide irrigations are widely used to help patients with paranasal sinus inflammation, but have never been tested as a treatment for olfactory loss. We sought to examine the effect of adding budesonide irrigation to olfactory training on patients with olfactory loss without any visible sign of sinonasal inflammation. METHODS: In this randomized, controlled trial, 138 patients with olfactory loss and without any visible sign of sinonasal inflammation were randomized to either OT with saline irrigations or OT with budesonide irrigations...

  African rhinoceros are poached for their horns using indiscriminate and aggressive methods. Rhinoceros that survive these attacks often have severe facial trauma, and treatment is limited by a lack of understanding and published information of the normal anatomy. This study was performed to investigate and describe the anatomy of the most commonly injured area of the head of the white rhinoceros ( Ceratotherium simum). Two white rhinoceros cadaver heads were imaged by computed tomography and grossly dissected...

INTRODUCTION: The most common cause of septoplasty failure is inferior turbinate hypertrophy that is not treated properly. Several techniques have been described to date: total or partial turbinectomy, submucosal resection (surgical or with a microdebrider), with turbinate outfracture being some of those. OBJECTIVE: In this study, we compared the pre- and postoperative lower turbinate volumes using computed tomography in patients who had undergone septoplasty and compensatory lower turbinate turbinoplasty with those treated with outfracture and bipolar cauterization...

Nasalisation is a surgical technique proposed for the treatment of nasal polyposis in 1995. The technique as initially described was based on large opening of the maxillary, sphenoidal and frontal ostia and resection of the middle turbinates, with the aim of resecting the mucosa of the lateral masses of the ethmoid as completely and safely as possible. Recent findings on the evolution and development of the nose and sinuses and sinus physiology allow both the concept and the technique of nasalisation to be updated...

REVIEW
D Wu, C S Wang, L Zhang
Sinonasal inverted papilloma is the most common seen benign disease of nasal cavities and paranasal sinuses area characterized by great recurrence rate and malignancy tendency. The infection of human papillomavirus is considered as a risk factor playing a role underneath the mechanism. However, the association between the infection of HPV and the recurrence or malignancy of SNIP remains controversial. By summarizing the existing research results, this paper further explores the association between HPV infection and SNIP...

The anterior skull base (ASB) is intimately associated with the unique soft tissue subtypes of the nasal cavity, paranasal sinuses, orbits, and intracranial compartment. Pathology involving the ASB is rare but the causes are manifold and can be broadly subdivided into those intrinsic to the skull base and processes extending from below or above. Sinonasal pathology is the most commonly encountered and poses significant management challenges that rely heavily on accurate interpretation of the radiological findings...

Objectives  The use of nasopharyngeal landmarks to localize the petrous apex has not been previously described. We describe a purely endoscopic endonasal corridor to localize the petrous apex without transgressing any of the paranasal sinuses. Methods  Anatomical dissections of four formalin preserved cadaveric heads (eight petrous apices) were performed to evaluate the feasibility of a nonsinus-based approach and illustrate the surgical landmarks and measurements that are useful for surgery in this area...

Dyke-Davidoff-Masson Syndrome (DDMS) is a rare neurological condition characterised by drug-resistance seizures, hemiparesis, mental retardation, facial asymmetry, and intellectual disabilities. On brain imaging, the disease is characterised by cerebral hemiatrophy with ipsilateral calvarial thickening and hyperpneumotisation of paranasal sinuses or mastoid air cells. Although more common in men and on the left side of the brain, the disease can affect both genders and cerebral hemispheres. It mainly presents in childhood...

Fibrous dysplasia is a slow growing fibro-osseous tumor, which is infrequent in craniofacial location and very rarely found in paranasal sinuses. Its occurrence is usually in children and young adolescents. The complications common in this location are related to the sinus ostia obstruction, like sinusitis or mucocele formation. Aneurysmal bone cyst formation has also been reported. We present a case of frontoethmoid fibrous dysplasia which extends to the nasal cavity and extraaxial frontal region. The peculiarity about the case is its association with the intradiploic CSF cyst formation, which to best of our knowledge has never been reported before...
