The cases of 80 patients who underwent Caldwell-Luc surgery for the treatment of chronic rhinosinusitis between 2002 and 2007 at Vanderbilt University Medical Center's Department of Otolaryngology were reviewed. Data on demographics, comorbidities, details of surgery, surgical pathology, and histology were collected. These data were compared with those of 40 patients who underwent standard functional endoscopic sinus surgery in 2007. Statistically significant differences were found in terms of mean patient age, sex, mean number of sinuses surgically addressed, number of prior surgeries, and tissue eosinophil counts. Microscopic examination revealed the presence of "necrotic bone" in 2 Caldwell-Luc specimens, and "necrotic debris" in 2 other Caldwell-Luc specimens. No similar finding was seen in the control group. Caldwell-Luc is a surgery of last resort for patients who fail aggressive interventions for maxillary sinus disease. The mucosal lining of this small group of patients appears to be different from that of patients who respond favorably to functional endoscopic sinus surgery.

Introduction: The differential diagnosis of orbital complications of rhinosinusitis with diseases of the lacrimal sac in childhood remains unresolved both due to the similarity of the symptoms of the diseases and due to certain diagnostic difficulties requiring computed tomography.
Objective: To develop an algorithm for routing a patient to the emergency department of a multidisciplinary emergency hospital based on clinical and diagnostic distinctive features of sinusitis with orbital complications and diseases of the lacrimal sac with reactive edema of the eyelids.
Materials And Methods: A retrospective cohort analysis of children's medical histories, who were treated in the otorhinolaryngological and ophthalmological departments of the Morozovskaya Children's City Clinical Hospital during 2022 was performed for orbital complications of rhinosinusitis or dacryocystitis with reactive edema of the eyelids.

This study investigated the effect of platelet-rich fibrin (PRF) on bone healing around implants placed in elevated sinus cavities. Forty New Zealand albino rabbits were divided into eight groups, based on the time of sacrifice (14 or 40 days) and the material used: blood clot (control), hydroxyapatite (HA) from bovine bone, HA combined with PRF, and PRF alone. Each group consisted of five animals (n = 5).

Background: A comprehensive investigation to associate the use of polynucleotides and hyaluronic acid with bovine bone in maxillary sinus lift procedures in rabbits has not been performed yet. The aim was to evaluate the influence of this novel association on the processes of bone regeneration in maxillary sinus augmentation.
Methods: In this prospective, randomized, within-animal model, maxillary sinus augmentation was performed bilaterally in 12 rabbits.

Nasal and paranasal sinus masses can arise from a wide range of conditions, both benign and malignant, as well as congenital or acquired. Diagnosing these masses is often challenging, requiring a combination of nasal endoscopy, imaging studies, and histopathological analysis. Initial imaging frequently involves computed tomography or cone beam computed tomography (CBCT) to evaluate the bony anatomy of the nasal cavity and surrounding sinuses, while magnetic resonance imaging (MRI) is typically used for detailed assessment of soft tissues and to aid in differential diagnosis when the findings are inconclusive.

Material And Methods: Using multi-slice computed tomography (MSCT), the study examined the structure and relationships of key anatomical features, including the alveolar process, sinus wall thickness, and the position of the teeth in relation to the maxillary sinus.
Results: The results revealed that the lower wall of the maxillary sinus is predominantly formed by the alveolar process, with significant variability in wall thickness, especially between the central and lateral regions.
