RESUMEN

Generally, revision rhinoplasty cases require the use of stiff grafts to restore the lost support. However, the majority of patients indicated for revision surgery present with a lack of a bony cartilaginous framework of the septum, especially after previous septoplasty. Thus, surgeons are compelled to harvest costal cartilage. At the same time, rib graft harvesting is associated with additional trauma and a risk of serious complications. Being ENT surgeons, we often resect a part of the lateral wall of the inferior nasal meatus during the extended endoscopic approach to the maxillary sinus. We supposed that this bone plate could be used as a donor site for rhinoplasty graft harvesting. The aim of our study was a radiological assessment of the feasibility and limits of using the inferior meatus lateral wall (IMLW) as a donor site for rhinoplasty bone graft.A retrospective evaluation of 100 CT scans of sinuses was conducted. Further measurements of the IMLW were performed: average length and width (28.06 ± 4.03 mm and 19.73 ± 3.08 mm, respectively), thickness (0.62 ± 0.21 mm), and average deviation from the sagittal plane (17.7 ± 9.53 degrees). According to the obtained measurements, the described donor site is appropriate for harvesting nice straight bony fragments.The IMLW bone graft was used in four revision rhinoplasty cases. There were no postoperative complications. During the long-term follow-up, patients reported significant improvement in aesthetics, function, and social aspects according to Rhinoplasty Outcome Evaluation. Thus, the described technique is an easy and safe method for bone harvesting for revision rhinoplasty. Our first experience demonstrated the convenience and stability of IMLW grafts for revision rhinoplasty during the follow-up period of up to 2 years.

RESUMEN

Endoscopic repair of large nasal septal perforation (SP) remains a rather challenging procedure. The presented modification of vascularized flap, which is supplied with branches of posterior septal artery, has proven to be convenient and effective in closure of SPs larger than 2 cm.

RESUMEN

BACKGROUND: The heterogeneity of nasal features across different ethnical groups is evident. This large-scale multicenter study evaluates dorsal keystone area and its relation to superficial nasal anatomy, through computed tomography (CT) scans. METHODS: Six different populations were included: South Caucasian, Middle Eastern, Black South African, Eastern Asian, Mestizo and Eastern European. Each center obtained CT scans performed between January 2020 and December 2022 from patients presenting a nasal hump and from an age and sex-matched control group. Osteocartilaginous measurements in relation to Ethmoidal-point and to Rhinion, as well as their relation to superficial nasal anatomy, were collected from nasal CT scans in midsagittal view. These were compared between populations and, in each center, compared between patient groups (nasal hump versus no nasal hump). RESULTS: The study population included 600 patients (254 with nasal hump), with a mean age of 33.98 (ranging 18 - 59) years old, and 55.6% were female. The distance from the Ethmoidal-point averaged: to Rhinion 10.1(±3.5)mm; and to nasal hump beginning point 1.68 (±0.23)mm. In 96% of cases the Ethmoidal-point was cranial or no more than 5mm caudal to the beginning of the nasal hump. S-shaped nasal bones were associated with nasal hump but its angulation (kyphion angle) did not correlate with nasal hump height. CONCLUSIONS: In most patients, the nasal hump has no ethmoid bone underneath it, and it apex is located over the septal cartilage. The Ethmoidal-point is a reliable landmark and should be considered when appreciating established and new preservation and structural rhinoplasty approaches.

RESUMEN

Deviated nose correction is one of the most challenging procedures in rhinoplasty. Recent studies proposed effectiveness of preservation techniques even for patients with crooked nose deformity, although the long-term results are still controversial. Obviously, only addressing the blocking points is not enough to achieve stable midline position in crooked nose. To ensure consistent long-term results, we proposed a unilateral suturing of the bony pyramid along with unilateral resection of the excessive bone along the lateral osteotomy line. The first results of described surgical technique have proven its simplicity, reliability, and high efficiency both in primary and in revision surgeries.

RESUMEN

INTRODUCTION: Head and neck cancer (HNC) is the fifth most common cancer globally. Diagnosis at early stages are critical to reduce mortality and improve functional and esthetic outcomes associated with HNC. Metabolomics is a promising approach for discovery of biomarkers and metabolic pathways for risk assessment and early detection of HNC. OBJECTIVES: To summarize and consolidate the available evidence on metabolomics and HNC in plasma/serum, saliva, and urine. METHODS: A systematic search of experimental research was executed using PubMed and Web of Science. Available data on areas under the curve was extracted. Metabolic pathway enrichment analysis were performed to identify metabolic pathways altered in HNC. Fifty-four studies were eligible for data extraction (33 performed in plasma/serum, 15 in saliva and 6 in urine). RESULTS: Metabolites with high discriminatory performance for detection of HNC included single metabolites and combination panels of several lysoPCs, pyroglutamate, glutamic acid, glucose, tartronic acid, arachidonic acid, norvaline, linoleic acid, propionate, acetone, acetate, choline, glutamate and others. The glucose-alanine cycle and the urea cycle were the most altered pathways in HNC, among other pathways (i.e. gluconeogenesis, glycine and serine metabolism, alanine metabolism, etc.). Specific metabolites that can potentially serve as complementary less- or non-invasive biomarkers, as well as metabolic pathways integrating the data from the available studies, are presented. CONCLUSION: The present work highlights utility of metabolite-based biomarkers for risk assessment, early detection, and prognostication of HNC, as well as facilitates incorporation of available metabolomics studies into multi-omics data integration and big data analytics for personalized health.

RESUMEN

A key point, that determines the late outcome of push-down procedures, is a stable fixation of the bony pyramid in its new position. Therefore, rhinoplasty surgeons are consistently trying to find the effective technique for fixation of the osseocartilaginous vault that has been investigated. Nonetheless, all described techniques are less or non-effective in cases when simultaneous septoplasty is required. Thus, we have found more relevant a lateral fixation of the bony pyramid. Using a needle piezotome, two holes above and below lateral osteotomy lines should be performed bilaterally. The downward inserted pyramid is fixed with maxilla-pyramid sutures through these holes.Level of Evidence IV This journal requires that authors assign a level of evidence to each article.

RESUMEN

BACKGROUND: Despite the many described techniques, surgical repair of iatrogenic nasal septal perforations is still challenging. The authors present a novel technique for endoscopic closure of postoperative and recurrent nasal septal perforations. METHOD: The technique is based on the elevation of a vascularized flap from the L-strut area and the creation of the bed site without dissection of the surrounding septum. Seven patients were operated using "L-strut overlay" flap from June 2018 to October 2020. All patients had their perforations closed 12 months after surgery. CONCLUSION: Early results of our surgical technique have proven its simplicity and high effectiveness.

RESUMEN

OBJECTIVES/HYPOTHESIS: This study aimed to evaluate the olfactory status in children with laboratory confirmed SARS-CoV-2 using subjective and psychophysical methods. STUDY DESIGN: Prospective clinical cross-sectional study. METHODS: This is a prospective clinical cross-sectional study of 79 children with COVID-19. The 21st item of SNOT-22 questionnaire and odor identification test were used for smell assessment. Children were examined twice during the hospitalization, and a telephone survey was conducted 60 days after hospital discharge. RESULTS: Immediately after confirmation of COVID-19, smell impairment was detected in 86.1% of children by means of the Identification test and in 68.4% of children by means of the survey (P = .010). After 5 days survey revealed a statistically significant decrease in the number of patients with hyposmia (41 out of 79, 51.9%). On the first visit, the mean Identification test score corresponded to "hyposmia" (9.5 ± 2.7), while on the second visit, the average value was 13.1 ± 1.9, which corresponded to "normosmia." According to the telephone survey, recovery of the olfactory function occurred within 10 days in 37 of 52 patients (71.2%), 11 to 29 days - in 12 children (23.1%), and later than 30 days - in three cases (5.7%). CONCLUSIONS: In the pediatric population, olfactory dysfunction is an early and common symptom of COVID-19. There is a trend to quick recovery of olfactory function in children with COVID-19. The overwhelming majority of patients (94.3%) had no subjective olfactory complaints by the end of the first month. LEVEL OF EVIDENCE: 4 Laryngoscope, 131:E2475-E2480, 2021.

RESUMEN

OBJECTIVE: Being increasingly faced with the problem of pediatric nasal septal perforations, we have found that the surgical management of nasal septal perforations in children is not widely described in the litrature. The objective of our study was to demonstrate the results of different surgical techniques, including two original endoscopic techniques, in the septal perforation repair in children. METHODS: 24 children, ranging between 6 and 17 years of age, with nasal septal perforations were operated using different endoscopic techniques from February 2015 to May 2019 at the special tertiary referral clinic. Apart from well-known techniques, such as anterior ethmoidal artery flap, intranasal bipedicled advancement flap, sublabial flap, free temporal fascia graft, we used two original techniques - inverted edges technique and cross-septal returned flap. RESULTS: The total rate of complete perforation closure was 79% (19 of 24 patients). Regarding the reduction of symptoms, the efficacy of surgery was approaching 100%. The combination of inverted edges technique and anterior ethmoidal artery septal flap demonstrated the best results with no reperforations in all 10 cases. Using cross-septal returned flap, we achieved complete closure of perforation in 5 (83%) of 6 patients. The remaining techniques were performed rare and showed relatively low rates of success. There were 2 cases of complications (oronasal fistula), both developed in patients with sublabial mucosal flap. CONCLUSION: Use of endoscopic assistance, vascularized mucoperichondrial flaps and bilateral closure demonstrates high effectiveness in septal perforation surgical repair in children. LEVEL OF EVIDENCE: 4.
