Abstract
INTRODUCTION Nasal valve compromise is a common issue for patients presenting to an otolaryngologist. Anatomically, the dorsal septal cartilage (DSA) articulates with the upper lateral nasal cartilage (ULC). When the ULC weakens, it is prone to collapse and may result in nasal obstruction. Our objectives were to analyze histological differences between quadrangular and DSA nasal cartilages and compare histological composition of these tissues among patients with diagnosis of nasal valve compromise (NVC) versus those without NVC (no NVC). METHODS Prospective cross-sectional study of nasal cartilages from seventy-three (73) live donors. Quadrangular cartilage (QC), and DSA from patients undergoing septorhinoplasty were collected. Safranin O histochemical staining was used to observe glycosaminoglycans (GAGs) content and cell count. Masson's Trichrome staining was used to assess collagen content in these nasal cartilages. RESULTS Mean GAG content was lower in DSA compared with QUAD cartilage (68.18% vs. 87.22%, p < 0.0001), and was lowest in DSA of patients with NVC (59.07%). Mean collagen content was higher in DSA compared with QUAD cartilage, (65.43% vs. 46.65%, p = 0.0002), and was highest in DSA of patients with NVC (74.86%). CONCLUSION The DSA showed decreased GAG and increased collagen content compared with quadrangular cartilage. Within the DSA subsite, patients with presurgical NVC had the lowest GAG and highest collagen levels. This observation suggests that the biochemical composition of the DSA may contribute to its weakening, potentially resulting in its inability to withstand minor trauma and/or the effects of aging, ultimately leading to NVC. LEVEL OF EVIDENCE N/A Laryngoscope, 134:4252-4258, 2024.

Abstract
Diagnosis in rhinology is currently based on the concept of inflammation (chronic rhinosinusitis [CRS]) or the clinical concept of chronic nasal dysfunction (CND). The complementarity between these two approaches can be discussed by a critical review of the literature structured by the analysis of the fundamental and diagnostic bases and the therapeutic implications linked to each. The concept of CRS is based on the anatomical continuity of the nasal and sinus respiratory mucosa and molecular biology data, seeking to analyze the mechanisms of chronic inflammation and to identify proteins and biomarkers involved in the different supposed endotypes of chronic inflammation of this mucosa. The concept of CND seeks to analyze medical, instrumental or surgical diagnostic and therapeutic strategies, taking account of both inflammatory and non-inflammatory causes impacting the anatomy or physiology of each of the three noses (olfactory, respiratory and sinus) that make up the mid-face sinonasal organ of evolution-development (Evo-Devo) theory. Thus, the concept of CRS offers an endotypic approach, based on biological characterization of mucosal inflammation, while the concept of CND offers a compartmentalized phenotypic and pathophysiological approach to sinonasal diseases. The joint contribution of these two concepts in characterizing nasal functional pathology could in future improve the medical service provided to patients.

Abstract
BACKGROUND Dorsal preservation (DP) caused privilege change in the concept of rhinoplasty and a promising superior functional and aesthetic transformation in rhinoplasty surgery. Avoiding dissection of the dorsal nasal bone and cartilage will leave the soft-tissue envelope intact, leading to a fine and smooth appearance, faster operation with less subsequent edema, and overall preservation of the dorsal aesthetic line. METHODS This prospective study included 113 patients who underwent DP rhinoplasty for nasal hump treatment with minimum dissection of nasal dorsum soft-tissue envelope. Results were evaluated using the Standardized Cosmesis and Health Nasal Outcomes Survey (SCHNOS). RESULTS The mean preoperative SCHNOS score was 7.21; the mean obstructive score was 2.95 ± 1.068 and the mean aesthetic score was 4.27 ± 0.771. The average lowering of the dorsal hump was 4.4 mm. Approximately 96% of patients showed improvement in the SCHNOS score after surgery, 86.7% (98 patients) showed improvement in the obstructive symptoms and 95.6% (108 patients) showed improvement in the aesthetic score. Complications were seen in 22.11% (most commonly residual hump in 13.27% of cases and dorsal indentation in 5.31%), bleeding was seen in 2.65%, and granuloma formation at the dorsal osteotomy site was seen in 0.88%. There was a very significant improvement in the aesthetic, obstructive, and overall SCHNOS score ( P = 0.000) for each parameter. CONCLUSIONS DP rhinoplasty is a safe and very effective procedure, with very low risk of complications. Most of the treated patients have improvement of the obstructive and aesthetic outcome after surgery. CLINICAL QUESTION/LEVEL OF EVIDENCE Therapeutic, IV.

Anatomy of the nasal latero-lateral cartilage articulation: a micro-MRI study in human specimens. SURGICAL AND RADIOLOGIC ANATOMY : SRA 2022; 44:1367-1374.

Abstract
PURPOSE To study the anatomy of the latero-lateral joint (LLJ) between the upper lateral (ULC) and lower lateral (LLC) crus of the nasal cartilages, usually described as a scroll articulation. METHODOLOGY Six nasal pyramids were taken in monobloc from fresh cadavers and imaged on micro-MRI with 0.4 mm slice thickness. Images were jointly interpreted by two head and neck radiologists and one surgeon. The junction between the ULC and LLC, the presence of ligaments and of sesamoid or accessory cartilages were assessed. RESULTS Eight LLJs could be analyzed, with four types of junctions: hook-shaped cephalic border of the LLC turned towards the nasal fossa and linear caudal border of the ULC (n = 3), hook-shaped caudal border of the ULC and linear cephalic border of the LLC lateral crus (n = 1), hook-shaped border of both cartilaginous edges with clinging (n = 1) (scroll articulation) or without clinging (n = 3). No ligament or sesamoid cartilage was found, but posterior accessory cartilages were seen in 75% of the cases. CONCLUSION The classical scroll articulation of the LLJ has been observed in only 1/8 cases on micro-MRI images. The anatomy of the LLJ could explain the surgical difficulty in raising the tip of the nose in some patients and not in others.

Abstract
The process by which upper respiratory tract structures have changed over deep evolutionary time is, in part, reflected in the process of embryologic development. The nasopharynx in particular is a centrally located space bounded by components of the respiratory portion of the nasal cavity, cranial base, soft palate, and Eustachian tube. The development of these components can be understood both in terms of embryologic structures such as the branchial arches and paraxial mesoderm and through fossil evidence dating as far back as the earliest agnathan fish of the Cambrian Period. Understanding both the evolution and development of these structures has been an immeasurable benefit to the otolaryngologist seeking to model disease etiology of both common and rare conditions. This discussion is a primer for those who may be unfamiliar with the central importance of the nasopharynx both in terms of our evolutionary history and early embryological development of vital cranial and upper respiratory tract structures.
