Introduction: The anterior ethmoidal artery (AEA) has a trajectory with multiple anatomical variations. In addition, there are no clear references to locate it, so it is easy to produce an iatrogenic lesion. The goal of this study was to carry out a bibliographical review to analyse variants and endoscopic reference reports in the scientific literature.
Material And Methods: A review in Medline and Embase data bases was carried out, looking for AEA-related anatomical and radiological studies. After the revision, the principal study results, together with several distances and angles useful for locating the AEA, are presented in this study.
Results: There were 13 main articles that analysed a total of 1388 AEA. It was absent from 2 to 14%. It was identifiable in computed tomography (CT) between 95 and 100%. It was located between the second and third ethmoidal lamella in 74.2% and at the skull base level in 66.6%. Ethmoidal sinuses pneumatisation was related to AEA location at the skull base. Between 83 and 85.3%, it was found at the suprabullar recess.
Conclusions: CT is useful for presurgery planning. AEA are more frequent between the second and third lamella and at skull level. Ethmoidal pneumatisation and Keros grades could be predictive factors for AEA relationship with the skull base level. The AEA, the axilla of the middle turbinate and the superomedial edge of the nose are in a straight line, being a simple and useful reference in endoscopic sinus surgery.

With their close anatomical relationship, the temporomandibular joint (TMJ), mandibular ramus, skull base, ear, and infratemporal fossa make up a complex structure that may collectively be referred to as the 'TMJ and adjacent structures complex' (TASC). This study presents the neoplasms that may be encountered in the TASC region and their classification, which may be useful for the surgical treatment. Data of 1022 consecutive patients treated with resection of TASC neoplasms from May 2000 to October 2022 were reviewed.

Objective: This study aimed to assess postoperative intracranial pressure in patients with clinical and/or radiological features of idiopathic intracranial hypertension (IIH) undergoing endoscopic endonasal surgery for primary cerebrospinal fluid (CSF) leak repair.
Methods: Data was prospectively collected from 9 patients diagnosed with CSF nasal leaks who underwent corrective endonasal surgery between January 1, 2021, and October 31, 2022. Postoperative intracranial pressure was measured via lumbar puncture at least one month after surgery.

Autosomal recessive hypophosphatemic rickets type 2 (ARHR2) is an uncommon hereditary form of rickets characterised by chronic renal phosphate loss and impaired bone mineralisation. This results from compound heterozygous or homozygous pathogenic variants in ectonucleotide pyrophosphatase/phosphodiesterase 1 (ENPP1), a key producer of extracellular inorganic pyrophosphate (PPi) and an inhibitor of fibroblast growth factor23 (FGF23). ENPP1 deficiency impacts FGF23 and increases its activity.
