Isolated fractures of the orbital floor or medial wall are often referred to as blowout fractures (BOFs). Debilitating double vision and aesthetic deformity may affect the patients' quality of life and daily living skills, for instance, working or driving a car. The management of blowout fractures is, however, challenging, since not all fractures demand surgery. Some patients may have symptoms which subside, or may never develop symptoms. Due to a lack of evidence, there are still considerable differences in opinion on the criteria for surgery...

BACKGROUND: Skull base meningoencephaloceles are a rare condition, frequently secondary to traumatic or iatrogenic causes. Cerebrofacial arteriovenous metameric syndrome (CAMS) is characterized by the presence of retinal, facial and cerebral arteriovenous malformations (AVMs) with metameric distribution. To the best of our knowledge, this is the first reported case associating these two conditions. CASE DESCRIPTION: A 45 years old female previously diagnosed with CAMS type 2 presented with a long history of cerebrospinal fluid (CSF) rhinorrhea...

Common anatomic variants of the middle nasal turbinate include its pneumatization (i.e. concha bullosa media) and its paradoxical curvature. We report here two cases of differently combined variations of the middle turbinate which were documented in cone beam computed tomography (CBCT). The first report presents the vertical combination of a double or septated lamellar concha bullosa with the paradoxical curvature of middle turbinate. This combined variant associated (coincidental findings): ipsilateral paradoxical superior turbinate and contralateral paradoxical middle turbinate, concha bullosa superior and concha bullosa suprema...

An 84-year-old man presented to the emergency department following recurrent falls over several weeks and onset of new left-sided weakness. CT of the brain revealed a large air cavity (pneumatocoele) in the right frontal lobe thought to be secondary to an ethmoidal osteoma communicating through the cribriform plate allowing air to be forced into the skull under pressure. Subsequent MRI confirmed these findings and also revealed a small focal area of acute infarction in the adjacent corpus callosum. The patient had a prolonged hospital stay, declined neurosurgical intervention and was discharged home on secondary stroke prevention...

A 40-year-old drug addict, who was being treated with methadone and occupational therapy, committed suicide by striking a wooden pencil into his right eye socket. While still conscious, he hit his head hard against a table, jamming the pencil even deeper into his head. The autopsy showed that the pencil missed the globe and lodged in the inner part of the right eye socket. It pierced the orbital part of the right ethmoid bone, the right ethmoid cells, and the right superior nasal concha, then passed through the body of the sphenoid bone and the clivus of the occipital bone before stopping in the brain tissue...

Olfactory neuroblastoma is a rare malignant tumor of neuroectodermal origin and represents the most common cancer of the nasal cavity in pediatric age. The gold standard of treatment consists of en bloc resection, numerous studies have shown as the endoscopic approaches permit good control of the disease improving the quality of life after the treatment. Herein we describe the case of a 13-year-old patient referred to our outpatient clinic with a polypoid multi-lobed lesion occupying the left nasal cavity and imaging that confirmed a left-sided nasal mass without cribriform plate involvement (Kadish B)...

Background: The nasal septum is composed of cartilaginous and bony components and an understanding of each component volume is essential in both functional and cosmetic surgery. Objectives: We sought to radiographically measure septal dimensions on cross sectional computer tomography (CT) images, establishing average parameters for normal anatomy among a single, Caucasian population group. Methods: One hundred and fifty consecutive sinus CT scan images were examined and 100 cases with appropriate sagittal views were included in the study...

BACKGROUND: The International Frontal Sinus Anatomy Classification (IFAC) is an international consensus document published in 2016 to standardize the nomenclature of cells in the region of the frontal recess and frontal sinus. The IFAC was designed to be surgically relevant and anatomically precise. The current study was undertaken to assess the prevalence of the frontal cell variants as defined by the IFAC, as well as to determine the interrater reliability of the IFAC. METHODS: Three independent reviewers examined triplanar nondiseased maxillofacial computed tomography (CT) scans to assess the anatomy of the frontal recess according to the IFAC system...

Arteries that supply the nasal septum and the lateral nasal wall include vessels that originate from the external carotid artery and from the internal carotid artery. A variety of local endonasal pedicle flaps can be used in different anatomical areas for endoscopic skull base reconstruction. The main flaps are based on terminal branches of the sphenopalatine artery and on anterior ethmoidal artery. This study will describe the anatomy of these vessels and their relationship with the main flaps.

A 48-year-old man presented to urgent care with recurrent epistaxis over 6 months. Initially, nosebleeds were controlled with packing or cautery. Ultimately, he was referred to ear, nose and throat department and underwent nasal endoscopy which revealed polypoid tissue. A biopsy of the polyp showed non-specific inflammation with no evidence of malignancy. Follow-up maxillofacial CT revealed a large mass lesion in the right maxillary sinus, right nasal fossa, much of the ethmoids and right sphenoid, with destruction of adjacent bony structures...

Sinus infections can be complicated by ocular infections and, in late phases, by brain parenchyma infection. The article debates the case of a 12-year-old patient suffering from paucisymptomatic maxillo-spheno-ethmoidal rhinosinusitis, which was later complicated by orbital cellulitis, ending with the development of a brain abscess. The treatment is complex, initially targeting the source of the infection through draining the collection by middle maxillary antrostomy and anterior posterior ethmoidectomy, then the ablation of the brain abscess and postoperatively with prolonged massive antibiotherapy...

Objectives: Meningioma recurrence remains a significant issue. No study has described the relationship between the clinical features and prognosis of communicating meningioma that primarily originates from the olfactory groove. The aim of the study was to identify prognostic factors of communicating olfactory groove meningiomas that could be stratified according to their risk of recurrence. Results: A Simpson grade one or two resection was achieved. Complications with cerebrospinal rhinorrhoea occurred in two patients: one required reoperation, and the other was managed successfully with external drainage of lumbar cistern...

Aneurysmal bone cysts (ABCs) are expansile cystic lesions that can affect any bone of the body. Whilst these lesions are histologically benign, the lesions are locally aggressive and can affect the integrity of the affected bone as well as surrounding structures. ABCs arising in the head and neck region, particularly the paranasal sinuses are rare and they are limited to case reports in the literature. Due to the proximity of critical anatomical structures and the visual apparatus, the potential complications can be devastating...
