Objective: The aim of this study was to examine and analyze the pathology contributing to severe bilateral nasal wall collapse seen in certain revision rhinoplasty patients and identify those surgical maneuvers in the previous nasal surgery, which may have contributed to this complication; suggest alternatives or modifying steps in nasal surgery to prevent lateral wall collapse; analyze consecutive revision rhinoplasties and identify those patients who have complete bilateral nasal collapse at the internal nasal valve; and analyze the results achieved after surgical reconstruction of complete bilateral nasal collapse.
Patients: We identified 49 patients, who presented from 1990 to 2000 for revision surgery, who had bilateral collapse of the upper lateral cartilage. All patients had at least one previous rhinoplasty and all but 14 patients had undergone two or more procedures. The patients were reconstructed with a conchal cartilage graft placed through an external rhinoplasty approach.
Results: All patients complained of nasal obstruction with forced nasal inspiration. The collapse was visualized on inspiration and when prevented with intranasal positioning of a bayonet, all patients experienced an immediate improvement in nasal breathing. Postoperatively, all patients experienced this same improvement in their nasal airway. Collapse was not identified in any of the patients after surgery. Two patients underwent revision because of cosmetic asymmetries.
Conclusion: We strongly recommend a cartilage overlay to reconstitute the rigid midline continuity of the upper lateral cartilages. Unfortunately, with any significant hump removal, this structural interruption is, to varying degrees, inevitable in most rhinoplasty techniques. The upper lateral cartilages can be sutured to circumvent some of the inferior drift, but this will not reconstitute the rigid lateral cantilever effect of the intact cartilage.

Objective: This study aims to determine the anatomical relationship between the posterior superior alveolar artery (PSAA) and the lateral wall of the maxillary sinus during preoperative radiological evaluations in the posterior maxillary dental region, as well as to evaluate the prevalence of PSAA and its potential associations with sinus pathologies.
Materials And Methods: This retrospective study is based on the analysis of Cone-Beam Computed Tomography (CBCT) data from 510 sinuses of 255 patients. The visibility of the PSAA vascular canal, artery diameters, vertical distance between the alveolar crest and the artery, and the distance to the sinus floor were measured in coronal sections.

Inverted papilloma is a rare, benign epithelial tumor of the nasal and sinus cavities with an unclear etiology. It usually presents as unilateral nasal obstruction. Diagnosis is histological, and treatment is primarily surgical.

Introduction: Obstructive sleep apnoea (OSA) is characterised by blood oxygen desaturations and sleep disruptions manifesting undesirable consequences. Existing treatments including oral appliances, positive airway pressure (PAP) therapy and surgically altering the anatomy of the pharynx have drawbacks including poor long-term adherence or often involving irreversible, invasive procedures. Bilateral hypoglossal nerve stimulation (HNS) is a new treatment for managing OSA, and this study is intended to determine whether an HNS system is a safe and effective treatment option for adults with OSA.

Introduction: The objective of this study was to evaluate the effects of the miniplate application sites in the maxilla and the applied force vector changes during skeletally supported facemask application in adolescent patients with unilateral cleft lip and palate (UCLP) using finite element model (FEM) analysis.
Methods: A FEM was obtained from a cone-beam computed tomography image of a 12-year-old female patient with UCLP. Miniplates were placed on 3 different sites of the maxilla; 500 g of advancement force was applied bilaterally, parallel (0°), and downward (-30°) to the occlusal plane.

: Rhegmatogenous retinal detachment (RRD) is a potentially blinding retinal disorder. RRD in the first eye is a well-recognized risk factor for bilateral RRD since risk factors that predispose to RRD affect both eyes. In this study, we assess the presenting factors that predispose individuals to bilateral RRD and evaluate the role of prophylactic retinopexy in preventing fellow-eye RRD.
