IMPORTANCE Although autologous rib cartilage is a preferred source of graft material in rhinoplasty, rib cartilage for dorsal augmentation has been continuously criticized for its tendency to warp and for high donor-site morbidities. However, no meta-analysis or systemic review on complications associated with autologous rib cartilage use in rhinoplasty has been conducted. OBJECTIVE To carry out a systematic review and a meta-analysis of available literature to evaluate complications regarding autologous rib cartilage in rhinoplasty. DATA SOURCES The studies reporting complications associated with the autologous rib cartilage use in rhinoplasty were systematically reviewed by searching the MEDLINE, PubMed, and Embase databases for sources published from 1946 through June 2013. STUDY SELECTION The selected articles included clinical studies conducted with at least 10 patients and at least 1 postoperative long-term complication or donor-site morbidity in rhinoplasty. Excluded were nonhuman studies; review articles; case reports; abstracts; and reports of nasal reconstruction as indication for surgery, use of homologous rib cartilage, and diced or laminated methods. DATA EXTRACTION AND SYNTHESIS Two investigators independently reviewed all studies and extracted the data using a standardized form. A meta-analysis was performed using a random-effects model. MAIN OUTCOMES AND MEASURES Number of patients; follow-up duration; and rates of complication, donor-site morbidity, and revision surgery. Also noted were study authors and year of publication. RESULTS Ten studies involving a total 491 patients were identified. Mean follow-up across all studies was 33.3 months. In meta-analysis, the combined rates were 3.08% (95% confidence interval [CI], 0%-10.15%) for warping, 0.22% (95% CI, 0%-1.25%) for resorption, 0.56% (95% CI, 0%-2.61%) for infection, 0.39% (95% CI, 0%-1.97%) for displacement, 5.45% (95% CI, 0.68%-13.24%) for hypertrophic chest scarring, 0% (95% CI, 0%-0.32%) for pneumothorax, and 14.07% (95% CI, 6.19%-24.20%) for revision surgery. CONCLUSIONS AND RELEVANCE The overall long-term complications and donor-site morbidity rates associated with autologous rib cartilage use in rhinoplasty were low. Warping and hypertrophic chest scarring showed relatively higher rates, warranting a surgeon's attention. Because a limited number of studies and patients were eligible, and consistent definitions of complications were lacking in this meta-analysis, future studies with a larger series of patients and objective outcome measurements are needed to obtain more reliable results.

Follow-up of postviral olfactory loss revealed that over 80% of the patients reported subjective recovery after one year. The more favorable prognosis was associated with longer follow-up duration and female gender.

BackgroundPopulation-based studies for olfactory dysfunction are lacking. The aim of this study is to evaluate the prevalence of subjective olfactory dysfunction and its risk factors in the Korean general population.MethodsThe data were obtained from the 2009 Korea National Health and Nutrition Examination Survey (KNHANES), which was a cross-sectional survey of non-institutionalized population all around the country (n = 10,533). All interviewees underwent medical interviews, physical examinations, endoscopic examination and blood/urine tests. Whether sense of smell has been normal or abnormal during the last 3 months was asked. Complete olfaction data were obtained from 7,306 participants and the participants were divided into normosmic and hyposmic group. Multivariate logistic regression analyses were performed to identify its risk factors.ResultsThe weighted prevalence of subjective olfactory dysfunction was 4.5%. Its increased prevalence was significantly associated with the increasing age for both men and women. In the multivariate analyses, low income (adjusted odds ratio [OR] = 1.43, 95% Confidence Interval [CI] = 1.01–2.03), habitual exposure to air pollutants (adjusted OR = 2.18, CI = 1.33–3.55), a history of hepatitis B (adjusted OR = 3.10, CI = 1.25–7.68), rhinitis (adjusted OR = 1.78, CI = 1.26–2.51) and chronic sinusitis (adjusted OR = 14.55, CI = 10.06–21.05) were risk factors of olfactory dysfunction.ConclusionOur population-based study showed that olfactory dysfunction was quite prevalent and several risk factors were associated with impaired sense of smell. Given its prevalence, further researches for its prevention and management are required.

Prevalence, risk factors, and comorbidities of AR were evaluated in the general Korean population, which will contribute to prevention and treatment of AR and its comorbidities in Koreans.

IMPORTANCE Studies comparing surgical results of rhinoplasty using autologous costal cartilage (ACC) and irradiated homologous costal cartilage (IHCC) are rare.OBJECTIVES To compare the clinical results of major augmentation rhinoplasty using ACC vs IHCC and analyze the histologic properties of both types of cartilage. DESIGN, SETTING, AND PARTICIPANTSA retrospective clinical study was conducted among patients who had undergone rhinoseptoplasty using ACC or IHCC from January 1, 2009, to December 31, 2014. Patients were followed up for more than 1 year after surgery and the histologic characteristics of ACC and IHCC were compared. The details of the surgical procedures and complications, including warping, infection, resorption, and/or donor-site morbidity, were evaluated by reviewing medical records and facial photographs. Patients' subjective satisfaction with aesthetic and functional results was evaluated using a questionnaire. MAIN OUTCOMES AND MEASURESThe details of the surgical procedures and complications, including warping, infection, resorption, and/or donor-site morbidity; patients' subjective satisfaction with aesthetic and functional results' objective evaluation of surgical outcomes, including symmetry, dorsal height, dorsal length, dorsal width, tip projection, tip rotation, tip width, and overall result; and histologic structures. Objective evaluation of surgical outcomes was graded using the Objective Rhinoplasty Outcome Score, which assessed symmetry, dorsal height, dorsal length, dorsal width, tip projection, tip rotation, tip width, and overall result. Histologic structures were evaluated using hematoxylin and eosin, Masson trichrome, Alcian blue, and Verhoeff elastic stains.RESULTS A total of 63 patients (27 males and 36 females; mean [SD] age, 30.6 [9.5] years) had rhinoseptoplasty using ACC and 20 (9 males and 11 females; mean [SD] age, 35.4 [15.4] years) had rhinoseptoplasty using IHCC. Among observed complications, only notable resorption occurred more frequently in patients using IHCC (6 [30%]) than with ACC (2 [3%]) (P = .002). In subjective evaluations of aesthetic satisfaction, patients who received ACC showed significantly greater satisfaction (37 of 51 patients [73%] were very satisfied) than did those who received IHCC (6 of 20 [30%]) (P = .001). However, there was no between-group difference in subjective functional outcomes: 4 of 51 patients receiving ACC (8%) and 5 of 20 receiving IHCC (25%) were satisfied (P = .50) and 45 of 51 receiving ACC (88%) and 15 of 20 receiving IHCC (75%) were very satisfied (P = .15). Regarding objective aesthetic outcomes, all scores for both ACC and IHCC were more than 3.1 (between good and excellent). Histologic analyses showed larger, more evenly distributed, uniform chondrocytes and more collagens and proteoglycan contents in ACC than in IHCC. CONCLUSIONS AND RELEVANCECompared with patients receiving IHCC, those receiving ACC for rhinoseptoplasty showed superior aesthetic satisfaction; ACC also had less frequent notable resorption.

After functional endoscopic sinus surgery (FESS), nasal packing may be necessary and a packing material which has benefits in both cost and efficacy would be required. This study aimed to determine the efficacy of Gelfoam packing on hemostasis and wound healing after FESS. Patients who underwent bilateral FESS due to chronic bilateral rhinosinusitis were enrolled. Randomly, one side was selected for Gelfoam packing and the other side for no packing. Subjective symptoms and objective findings such as synechia, granulation, pus discharge, edema, stenosis, and crust were evaluated. A total of 21 patients (17 men and 4 women; mean age 39.7 years ranging from 12 to 75 years) were included. There were no statistical significant differences between two groups regarding both subjective symptoms and objective findings during 4 months after surgery. Three patients had postoperative bleeding in the no packing side. Gelfoam packing may be recommendable in terms of efficacy and cost-benefit after FESS.
