ABSTRACT Introduction In patients with posterior epistaxis, generally the source of bleeding is branches of sphenopalatine artery (SPA), which enter the nasal cavity through the sphenopalatine foramen (SPF). Cases of intractable massive bleeding may require endonasal endoscopic occlusion of these vessels. Materials and methods A total of 32 hemisections of formalinfixed cadaveric heads were used. The anatomic variations of SPF, its distance from anatomical landmarks, and angle of elevation of endoscope were studied so as to facilitate accurate localization of the foramen and endoscopic arterial ligation. Results The SPF was generally single; however, multiple exits in the form of accessory foramina were found in 36.75% hemisections. The transition of superior and middle meatuses was the most common location of SPF, followed by the superior meatus, and middle meatus was the least common site. The accessory foramina were commonly present in the superior meatus. Ethmoid crest was distinctly visible in all but two cases. In majority of the cases, the SPF was located within a range of 55 to 65 mm from the anterior nasal spine (ANS); 60 to 70 mm from piriform aperture, 50 to 60 mm from limen nasi, 20.1 to 25 mm vertically above the floor of nasal cavity, and 8 to 15 mm from the inferior turbinate (IT). The angulation of SPF from the floor of nasal cavity was 20 to 30°. Conclusion Exploration of lateral nasal wall (LNW) up to middle meatus would minimize the risk of missing any arterial branch, and the data of distance from the anatomical references would assist in more precise localization of SPF during endoscopic ligation or cauterization of the branches of the SPA.

Abstract BACKGROUND. Functional endoscopic sinus surgery (FESS) is a reliable option in the treatment of sinus pathology, but the presence of the anatomical variant and difficult cases like massive polyposis or revision FESS can generate some problems to surgeons. MATERIAL AND METHODS. After performing an unciformectomy, a partial anterior ethmoidectomy and maxillary ostium antrostomy, we slide a cottonoid back to the basal lamella of the middle turbinate with a Cottle dissector and introduce it in the superior meatus. After that, we return to the middle meatus and proceed to open the basal lamella finding the cottonoid placed there previously. RESULTS. An easy technique, safe and reproducible, that allows us to advance in our dissection, avoiding damaging important structures. CONCLUSION. In this paper we present a safe way to approach the posterior ethmoidal cells complex in the classic way through the basal lamella of the middle turbinate, under the guidance of a cottonoid, a safe and easy maneuver to do this procedure in the beginning of our formation or in complex cases.

Objectives: To investigate the incidence of accessory maxillary sinus ostia in superior meatus in patients with clinical and radiological signs of maxillary sinusitis and the association with the development of chronic rhinosinusitis. Design: Retrospective study Setting: Tertiary care hospital Participant: 159 patients examined with paranasal sinus computed tomography scans Main outcome measures: We retrospectively evaluated patients who visited the outpatient department at an academic medical facility between January and April 2020 with a clinical diagnosis of chronic rhinosinusitis. Paranasal sinus axial and coronal computed tomography scans were evaluated for accessory maxillary sinus ostia in superior meatus and confirmed by reconstructed three-dimensional simulation images. The demographic information and incidence of accessory ostia in superior meatus were assessed. The Lund–Mackay score was used to rate chronic rhinosinusitis severity. Analysis of variance was performed to correlate the severity of chronic rhinosinusitis with presenting accessory ostia in superior meatus. Results: Of 159 patients (81 males; 78 females), 41.5% had accessory maxillary sinus ostia in superior meatus. Of these, two-thirds were bilateral and one-third was unilateral. The severity of rhinosinusitis was not correlated with having accessory maxillary sinus ostia in superior meatus, but the presence of accessory ostia was significantly associated with less severe chronic rhinosinusitis (P < 0.001). Conclusions: Accessory maxillary sinus ostia in superior meatus are significantly associated with less severe chronic rhinosinusitis and most cases are bilateral.

AbstractA case of chronic facial pain and headache is presented. This was found to be due to two pieces of windscreen-glass lodged in the superior meatus of the patient's nose since a road-traffic-accident 14 years earlier. Despite being reported as normal, review of previous X-rays of her sinuses showed that the glass was visible. The importance of carefully assessing the intranasal area on sinus-views is illustrated.
