Patient-reported outcome measures in external and endonasal functional septorhinoplasty - A propensity score matching study.

PURPOSE: Patient satisfaction after functional-aesthetic SRP (faSRP) is highly influenced by the cosmetic result of the surgical procedure. Studies that directly evaluate aesthetic success after external and endonasal faSRP are scarce. The objective of this prospective propensity score matching study was to compare patient-reported satisfaction regarding aesthetic perception following faSRP using the external and endonasal approach in a single-institution single-surgeon survey. MATERIALS AND METHODS: Out of 161 patients operated by the senior author between October 2011 and March 2017, propensity score matching (PSM) computed 54 patients each following external (group 1) or endonasal faSRP (group 2). Patients reported their satisfaction with the aesthetic appearance of the nose on a visual analogue scale (VAS, 0-10) and five Likert scale questions using the Utrecht questionnaire three and twelve months after surgery. RESULTS: The mean preoperative VAS score of 3.46 ± 1.06 improved significantly in all patients after faSRP to 4.54 ± 0.38 (F(1.69;157.04) = 634.01, p < 0.001). The VAS increase did not show any correlation to the surgical approach (F(1;93) = 1.12, p = 0.293). The mean aesthetic sum score (5 = low burden up to 25 = high burden) improved significantly from 13.89 ± 3.78 to 8.46 ± 3.63 after three months (t(95) = 14.021, p < 0.001) and remained almost unchanged after 12 months (8.10 ± 3.76; t(98) = 1.450, p = 0.150) irrespective of the surgical approach (F(1,544;143,587) = 0.126, p = 0.829). CONCLUSIONS: Both the external and endonasal faSRP allowed for significant improvement in patient's aesthetic self-assessment of similar extent.

Significant polyomic and functional upregulation of the PAPP-A/IGFBP-4/5/IGF-1 axis in chronic rhinosinusitis with nasal polyps.

BACKGROUND: Chronic rhinosinusitis with nasal polyps (CRSwNP) is associated with epithelial expansion and polyp survival. However, the molecular mechanism of this aberrant proliferation is unclear. The purpose of this study was to interrogate derangements of the pappalysin-A/insulin-like growth factor binding protein/insulin-like growth factor-1 (PAPP-A/IGFBP-4/5/IGF-1 axis) as a major contributing factor to polyp growth in CRSwNP. METHODS: Matched tissue and exosomal proteomic arrays including PAPP-A, IGFBP-4, IGFBP-5, and IGF-1 were quantified using aptamer-based methods/Western blots for proteomic analysis and whole-transcriptome sequencing/quantitative polymerase chain reaction (qPCR) for transcriptomic analysis in CRSwNP and control patients. Functional PAPP-A assays were then performed in both tissue and exosomes (set 1: n = 20 per group; validation set 2: n = 26 per group). RESULTS: Tissue and exosomal PAPP-A was significantly overexpressed in CRSwNP compared to controls on both a transcriptomic and proteomic level (p < 0.0001). Known inhibitors of PAPP-A (stanniocalcin-1/-2) were significantly downregulated (p < 0.0001) as were PAPP-A cleavage products (IGFBP-5 p < 0.0001). PAPP-A function was shown to be increased 5-fold to 6-fold in tissue and exosomes. CONCLUSION: Upregulated tissue and exosomal PAPP-A signaling is significantly associated with CRSwNP and may be an important factor in the promotion of epithelial proliferation and polyp growth. These data lend further support to the emerging concept of exosomal functional and polyomic analyses as a method to study sinonasal pathology.

Cartilage Scales Embedded in Fibrin Gel.

Multiple techniques have been described for dorsal nasal augmentation in rhinoplasty. In this article, we review common surgical techniques for raising the dorsum or eliminating dorsal irregularities, by highlighting inherent advantages and disadvantages of each method. Within the past few years, the use of diced cartilage grafts has become the workhorse in this field of interest. To overcome drawbacks of methods based on diced cartilage, we present a new concept for autologous augmentation, using regenerative medicine protocols. A mix of cartilage scales with cartilage pâté was embedded in platelet-rich fibrin (PRF). Since December 2015, a total of 48 patients were treated with this technique. Based on our preliminary results, cartilage scales in PRF appear to be a promising and reliable alternative to existing procedures for dorsal nasal augmentation.

Options for Middle Vault and Dorsum Restoration after Hump Removal in Primary Rhinoplasty.

Prevention of unfavorable sequelae following humpectomy in reduction rhinoplasty by restoration of the middle nasal vault complex today has become imperative in the majority of patients with perhaps the exception of small humps. In general, the techniques used for preservation and reconstruction of these important anatomical structures can be divided into two main categories: spreader graft and spreader flap techniques. Oversimplified spreader graft techniques require donor cartilage, whereas spreader flap techniques use the excess height of the medial portion of the upper lateral cartilages in patients with a cartilaginous hump. In principle, both donor cartilage and preserved upper lateral cartilages usually are positioned along both sides of the dorsal septum to provide natural and harmonious contours as well as to avoid functional impairment (valve collapse). However, the considerable number of publications on this topic attests to existing downsides of both surgical principles. To overcome these shortcomings, we illustrate additional modifications in the application of spreader grafts as well as spreader flaps. However, the main goal of this article is to provide an algorithm helping to decide which technique is best suited to meet the requirements of each individual patient.

Role of ultrasonography in the detection of a subperiosteal abscess secondary to mastoiditis in pediatric patients.

The aim of the study described here was to evaluate experience in the diagnosis of a subperiosteal abscess secondary to mastoiditis by means of ultrasound. Ten consecutive cases in which an ultrasound examination of the retro-auricular region was performed for suspected mastoiditis were identified. In nine cases, we found a poorly demarcated, inhomogeneous, irregular, poorly perfused lesion abutting the outer table of the cranial vault, with elevation of the outer periosteum and a clearly delineated defect of the cortical layer. In one case, there was additional invasion of the insertion of the sternocleidomastoid muscle on the mastoid process of the temporal bone, raising the suspicion of Bezold mastoiditis. Ultrasound may help in selecting patients for further imaging and might spare computer tomography, especially in sensitive patient groups such as children and pregnant women, if a defect of the outer cortex of the temporal bone can be excluded with certainty.

Spreader flaps for middle vault contour and stabilization.

Nasal hump excision is common during septorhinoplasty. Without appropriate restoration of the middle nasal vault, cosmetic and functional problems may ensue. Recently, spreader flaps have become an established alternative to traditional spreader grafts. Typical indications include primary rhinoplasty patients with hump noses, hump/tension noses, and moderately hooked or crooked noses. When suitable patients are selected, spreader flaps and their modifications represent a reliable alternative to the standard spreader graft, and when all of the necessary prerequisites are met, this technique obviates the need for additional cartilage grafting in most cases.

Cranial tip suture in nasal tip contouring.

The creation of both a functionally and aesthetically pleasing nasal tip contour is demanding and depends on various different parameters. Typically, procedures are performed with emphasis on narrowing the nasal tip structure. Excisional techniques alone inevitably lead to a reduction in skeletal support and are often prone to unpredictable deformities. But also long-term results of classical suture techniques have shown unfavorable outcomes. Particularly, pinching of the ala and a displacement of the caudal margin of the lateral crus below the cephalic margin belong to this category. A characteristic loss of structural continuity between the domes and the alar lobule and an undesirable shadowing occur. These effects lead to an unnatural appearance of the nasal tip and frequently to impaired nasal breathing. Stability and configuration of the alar cartilages alone do not allow for an adequate evaluation of the nasal tip contour. Rather a three-dimensional approach is required to describe all nasal tip structures. Especially, the rotational angle of the alar surface as well as the longitudinal axis of the lateral crus in relation to cranial septum should be considered in the three-dimensional analysis. Taking the various parameters into account, the authors present new aspects in nasal tip surgery which contribute to the creation of a functionally and aesthetically pleasing as well as durable nasal tip contour.
