PURPOSE: The preserved head of King Henri IV of France (life 1553-1610, reign 1589-1610) has survived to the present day thanks to high-quality embalming and favorable conservation conditions. The aim of this study was to examine Henry IV's upper resonant cavities and mastoids using an original and innovative forensic three-dimensional segmentation method. METHODS: The paranasal sinuses and mastoid cells of King Henri IV of France were studied by cross-referencing available biographical information with clinical and flexible endoscopic examination and computed tomography (CT-scan) imaging...

Nasal obstruction is a commonly reported issue in the Otorhinolaryngology Outpatient Department. In this case, an early adolescent boy with a long-standing problem of right-sided nasal obstruction since childhood sought consultation. Diagnostic nasal endoscopy revealed a deviation of the nasal septum to the left, coupled with right inferior turbinate hypertrophy, all overlying healthy mucosa. A CT scan of the nose and paranasal sinuses further identified a bony hyperdense lesion with ground glass attenuation, confined to the right inferior turbinate...

BACKGROUND: Environmental exposures have been postulated to play an important role in the pathophysiology of chronic rhinosinusitis (CRS). Particulate matter (PM) is one of the most widely studied ambient air pollutants, but its peri-operative impact on CRS is unknown. OBJECTIVE: To determine the effect of acute, peri-operative PM exposure on outcomes after endoscopic sinus surgery (ESS). METHODS: Participants with CRS who self-selected ESS were prospectively enrolled...

BACKGROUND: Headache is a common occurrence after endoscopic endonasal surgery (EES) for pituitary adenomas and significantly impacts the quality of life of patients. This study aims to investigate the effectiveness of nasal irrigation in relieving postoperative headache after EES. METHODS: A retrospective analysis was conducted on a cohort of 101 patients (Cohort I) who underwent EES for pituitary adenomas to explore the risk factors associated with postoperative headache...

BACKGROUND: Although endoscopic techniques have become more widespread in repair of frontal sinus (FS) defects, certain pathologies still require open approach (extensive trauma or tumors). Under certain circumstances even multiple complex open reconstructive procedures might fail to resolve persistent pneumocephalus or CSF leak and subsequently surgeons tend to escalate the invasiveness and employ even more complex and aggressive approaches. We present our experience treating persistent pneumocephalus or CSF leak after previously failed transcranial reconstruction utilizing an endoscopic endonasal approach (EEA)...

Introduction  Chronic rhinosinusitis (CRS) is a common inflammatory disease. This high prevalence leads to high direct and indirect public health costs, which include medical visits, laboratory tests and imaging, pharmacotherapy, hospitalizations, and surgical treatment. Furthermore, CRS has a substantial impact on patient quality of life, affecting productivity and being a common cause of absence from work CRS-associated olfactory dysfunction is highly prevalent, the actual effectiveness of surgical intervention remains inconsistent...

Introduction  Despite the high level of patient satisfaction with functional endoscopic sinus surgery (FESS) and the clinical improvement, polyp recurrence is observed in 23% to 87% of patients and requires reoperation. Objective  To assess the prognostic value of polypoid changes of the middle turbinate (PCMT) in relapse of paranasal sinus polyps in patients with chronic rhinosinusitis with nasal polyp (CRSwNP) after FESS and the effect of partial middle turbinectomy (PMT) on the outcome of surgery...

Introduction: Odontogenic maxillary sinusitis (OMS) is an infectious inflammatory pathology caused by a dental condition. Considering the anatomical relations with the orbit, maxillary sinus infection can easily spread, evolving into severe oculo-orbital complications that can sometimes be life-threatening. Material and methods: We performed a retrospective study of over 2 years, examining the data of 18 patients diagnosed with OMS with oculo-orbital complications. The patients were evaluated regarding their dental history, symptoms, clinical and endoscopic findings, ophthalmologic evaluation, bacteriologic tests, computed tomography (CT) imaging, medical and surgical treatment, and outcomes...

OBJECTIVES: Existing knowledge on health-related quality of life (HRQoL) after surgical removal of sinonasal inverted papilloma (IP) is limited. Moreover, predictors for a better or worse post-operative HRQoL outcome are not known. Our aim was to assess HRQoL in all three health domains (physical, psychological, and social), track its post-operative trajectory, investigate if pre-operative observations could predict distinct post-operative HRQoL outcomes, and evaluate whether physicians' interventions could contribute to improved post-operative HRQoL...

(1) Background: Transsphenoidal pituitary surgery can be conducted via microscopic or endoscopic approaches, and there has been a growing preference for the latter in recent years. However, the occurrence of rare complications such as postoperative sinusitis remains inadequately documented in the existing literature. (2) Methods: To address this gap, we conducted a comprehensive retrospective analysis of medical records spanning from 2018 to 2023, focusing on patients who underwent transsphenoidal surgery for pituitary neuroendocrine tumors (formerly called pituitary adenoma)...

RATIONALE: The present investigation documented a case of bilateral sinonasal inverted papilloma (SNIP) that arose from both sides of the frontal sinus and ethmoid sinus. The occurrence of bilateral involvement of the nasal cavities and frontal sinus is rather infrequent. PATIENT CONCERNS: Informed consent was obtained from the patient. DIAGNOSIS: Bilateral SNIP. INTERVENTIONS: The tumor was completely removed by Draf III endoscopic resection complemented by an external eyebrow arch approach, and the postoperative recovery was uneventful...

INTRODUCTION: This paper presents a camera sheath that can be assembled to various minimally invasive surgical instruments and provide the localized view of the instrument tip. MATERIAL AND METHODS: The advanced transformable head structure (ATHS) that overcomes the trade-off between the camera resolution and the instrument size is designed for the sheath. Design solutions to maintain the alignment between the camera's line of sight and the instrument tip direction during the transformation of the ATHS are derived and applied to the prototype of the sheath...

Chronic rhinosinusitis (CRS) is marked by inflammation of the paranasal sinuses and mucosal lining of the nose. CRS can be classified as CRS with nasal polyps or CRS without polyps. In recent years, there has been increased attention on the immunological role of vitamin D in treating CRS, coupled with the observation of vitamin D deficiency among CRS patients. Vitamin D is acknowledged for its immunomodulatory properties, especially in allergic conditions. Recent studies suggest that individuals with CRS, especially those with CRS with nasal polyps, frequently demonstrate lower than normal levels of vitamin D...

Chronic Rhinosinusitis with Nasal Polyps (CRSwNP) is a chronic inflammatory disease of the nose and paranasal sinus cavities that significantly affects well-being and social function, particularly in young adults and middle-aged populations. CRSwNP is a common health condition in the Western world, with an estimated prevalence of 3%. Despite worldwide evidence-based treatment guidelines such as the European Position Paper on Rhinosinusitis and Nasal Polyps (EPOS) 2020 and the European Forum for Research and Education in Allergy and Airway Diseases (EUFOREA) chronic rhinosinusitis (CRS) pocket guide, a significant number of patients remain undiagnosed and/or uncontrolled with repeated oral corticosteroids (OCS) treatments and/or (multiple) endoscopic sinus surgeries (ESS)...

Context: Human papillomavirus (HPV)-related multiphenotypic sinonasal carcinoma (HMSC), formerly known as HPV-related carcinoma with adenoid cystic like features, is a rare tumor subtype with unusual correlation between radiological, histopathological, and surgical findings. The shared histological characteristics with other sinonasal tumors make the diagnosis challenging. Optimal surgical and oncological treatments for this rare condition remains to be clearly defined. Methods: The objective of the study was to describe the unique characteristics and endoscopic surgical treatment of this rare tumor...

BACKGROUND: Studies in adult chronic rhinosinusitis (CRS) showed poor correlation between patient reported outcome measures (PROMs) and objective findings. Our goal is to study the correlation between the sinus and nasal quality of life (SN-5) and the 22-items sinonasal outcome test (SNOT-22) surveys with endoscopy findings in children with chronic adenoiditis (CA) and CRS. METHODS: Cross-sectional study of all pediatric patients (age 2-18) presenting for CA or CRS was performed...

OBJECTIVE: The anterior transpetrosal approach using a microscope to provide wider access to the petrous apex region has been described for radical resection of lesions of the middle and posterior skull base. The microscopic anterior transpetrosal approach (mATPA) requires a wide craniotomy and meticulous epidural procedures to minimize temporal lobe retraction. Recently, the clinical application of transcranial endoscopic keyhole approaches for minimally invasive surgery has been steadily expanding...

INTRODUCTION: A long-term ruxolitinib-treated patient with primary myelofibrosis, who was co-infected with aspergillosis infection during a short period, developed acute invasive fungal sinusitis with consequent orbit apex syndrome. This may be the first reported case in the world. This is a 75-year-old Chinese man; the patient was admitted with 2-month history of headache accompanied by numbness and 8-day history of vision loss. The preliminary clinical diagnoses were suspected acute invasive fungal sinusitis or adenoid cystic carcinoma...

Production of the high-molecular-weight forms of adrenocorticotropic hormone (big-ACTH) has been reported in a small number of ectopic ACTH syndrome and ACTH-producing pituitary macroadenoma. However, perioperative changes in big-ACTH in patients with subclinical Cushing's disease have not been reported. A 63-year-old woman presented 25 × 20 × 20-mm-sized macroadenoma in the pituitary gland. Her early morning plasma ACTH and cortisol levels were 111 pg/mL and 11...
