Radix saw: a useful tool for rhinoplasty to correct high radix / Serra de radix nasal: uma ferramenta útil na rinoplastia para corrigir o radix alto

Abstract Introduction: The most difficult aspect of radix lowering is determining the maximum amount of bone that can be removed with osteotomes; here, we describe use of a radix saw, which is a new tool for determining this amount. Objective: In this study, we describe use of a radix saw, which is a new tool to reduce the radix. Methods: The medical charts of 96 patients undergoing surgery to lower a high radix between 2016 and 2017 were assessed retrospectively. All operations were performed by the senior surgeon. Outcomes were assessed by comparing preoperative photographs with the most recent follow-up photographs (minimum of 6 months postoperatively). The photographs were all taken using the same imaging settings, and with consistent subject distance and angulation. The photographs were subsequently analysed by authors. Results: The study population consisted of 96 patients (70 women, 26 men) who underwent rhinoplasty between 2016 and 2017. The mean age of the patients was 28.8 years (range: 18-50 years) and the mean clinical follow-up period was 1.8 years. No patient required revision surgery due to radix problems, and there were no cases with unwanted bone fragments or radix asymmetry. The swelling and oedema seen immediately after surgery subsided after an average of 7-10 days. Conclusion: In conclusion, a radix saw can be used for rhinoplasty requiring delicate bone removal in patients with a high radix. Level IV: Evidence obtained from multiple time series with or without the intervention, such as case studies. Dramatic results in uncontrolled trials might also be regarded as this type of evidence.

Resumo Introdução: O aspecto mais difícil do rebaixamento do radix nasal é determinar a quantidade máxima de osso que pode ser removida com o osteótomo; aqui, descrevemos o uso de uma serra para radix nasal, uma nova ferramenta para redução dessa estrutura. Método: Prontuários médicos de 96 pacientes submetidos a cirurgia para redução do radix entre 2016 e 2017 foram avaliados retrospectivamente. Todas as cirurgias foram realizadas pelo cirurgião sênior. Os resultados foram avaliados comparando-se fotografias pré-operatórias com as fotografias de acompanhamento mais recentes (mínimo de 6 meses de pós-operatório). Todas as fotografias foram tiradas utilizando as mesmas configurações de imagem e com distância e ângulo consistentes do indivíduo. As fotografias foram posteriormente analisadas pelos autores. Resultados: A população do estudo foi composta por 96 pacientes (70 mulheres, 26 homens) que realizaram rinoplastia entre 2016 e 2017. A média de idade dos pacientes foi de 28,8 anos (18 a 50 anos) e o tempo médio de acompanhamento clínico foi de 1,8 anos. Nenhum paciente necessitou de cirurgia de revisão por problemas relacionados ao radix nasal e não houve casos com fragmentos ósseos indesejados ou assimetria do radix. O inchaço e o edema observados imediatamente após a cirurgia diminuíram após uma média de 7 a 10 dias. Conclusão: Uma serra para radix nasal pode ser utilizada para rinoplastia, exige manipulação óssea delicada em pacientes com radix alto, com nível de evidência IV. Evidência IV é obtida de várias séries temporais com ou sem intervenção, como estudos de caso. Resultados significativos em ensaios não controlados também podem apresentar esse tipo de evidência.

Absorbable Versus Non-Absorbable Sutures in Open Rhinoplasty: Analysis of Columellar Scarring.

INTRODUCTION: Open rhinoplasty involving columellar incision has gained popularity since the 1930s. Many surgical incision techniques have been employed to obtain better results in terms of postoperative scarring. This study evaluated and compared the results of absorbable and non-absorbable sutures used in open technique rhinoplasty, assessed scar properties regardless of the techniques used, from the perspectives of patients and surgeons. OBJECTIVE: This study evaluated and compared the results of absorbable and nonabsorbable sutures used in open technique rhinoplasty from the perspectives of patients and surgeons. MATERIAL AND METHODS: Study population included 70 patients who underwent primary open rhinoplasty between 2013 and 2018. Rhinoplasty Operations were performed in 2 different centers by a total of 2 rhinoplasty surgeons. Both surgeons used suture materials, which can be used for columellar closure, regardless of patients' skin characteristics. Columellar scars were assessed at an outpatient clinic at least 6 months postoperatively. Patients who could not come to the clinic were excluded from the study. Columellar Scars were assessed using the Turkish Patient Observer Scar Assessment Questionnaire. Patients were also asked to complete a Scar Assessment Analysis Questionnaire at the outpatient clinic, and were photographed from the front, basal, and right and left oblique sides. Three surgeons, who were not part of the research team but routinely performed rhinoplasty, completed the Observer Scar Assessment Questionnaire by examining patients in person at the clinic as well as their photographs. RESULTS: Observer Scar Assessment Questionnaire results; for the Vicryl group, surgeons ranked pigmentation of the scar as the best criterion (3.34 ±â€Š0.97) and irregularity of the scar as the worst (3.82 ±â€Š1.01). For the Prolene group, surgeons ranked irregularity as the best criterion (3.30 ±â€Š0.97) and stiffness as the worst (3.54 ±â€Š0.94). Although there was no statistically significant result between the two groups in the criteria, the mean scores of the Prolene group were less than the Vicryl group. (3.36 ±â€Š0.46, 3.50 ±â€Š0.65 respectively).Scar Assessment Analysis Questionnaire Results; patients in both the Vicryl and Prolene groups ranked pain as the least important factor (mean 2.9 ±â€Š1.11 and 3.33 ±â€Š1.35, respectively). The Prolene group scored lower than the Vcryl group in terms of overall scarring (3.49 ±â€Š0.72, 3.66 ±â€Š1.37, respectively, P > 0,05). CONCLUSIONS: Absorbable sutures are a convenient alternative to nonabsorbable sutures. LEVEL IV: Evidence obtained from multiple time series with or without the intervention, such as case studies. Dramatic results in uncontrolled trials might also be regarded as this type of evidence.

Awareness of Facial Asymmetry and Its Impact on Postoperative Satisfaction of Rhinoplasty Patient.

INTRODUCTION: Rhinoplasty surgeons often find that despite their best efforts to straighten the nose, patients often continue to perceive their nose as deviated, and this perception is particularly prevalent in patients with concurrent facial asymmetry. The aims of this study were to determine whether facial asymmetry influences the satisfaction of rhinoplasty patients and whether there is a difference in postoperative happiness between patients with and without facial asymmetry. MATERIALS AND METHODS: In this retrospective study, we reviewed the charts and photographs of patients who underwent rhinoplasty between 2016 and 2018. Patient photographs were analysed; 30 patients with facial asymmetry and 30 patients with symmetric faces were randomly selected for the study. The preoperative and postoperative rhinoplasty outcome evaluation (ROE) and standardized cosmesis and health nasal outcomes survey (SCHNOS) scores were compared between the two groups. RESULTS: The mean preoperative symmetry scores of the group with facial asymmetry were significantly higher than those of the group with symmetric faces. The magnitude of increase in the average ROE score from pre- to postoperatively was significantly larger in the group with symmetric faces than in the group with facial asymmetry. The magnitude of decrease in the mean SCHNOS score from pre- to postoperatively was significantly larger in the group with symmetric faces than in the group with facial asymmetry (p: 0.006). CONCLUSION: It is important to clearly evaluate patients with facial asymmetries before surgery to increase their postoperative satisfaction and outcomes and make their expectations more realistic.

Effects of turbinoplasty versus outfracture and bipolar cautery on the compensatory inferior turbinate hypertrophy in septoplasty patients / Efeitos da turbinoplastia versus fratura lateral e cauterização bipolar no volume da concha inferior hipertrófica compensatória em pacientes submetidos a septoplastia

Abstract Introduction: The most common cause of septoplasty failure is inferior turbinate hypertrophy that is not treated properly. Several techniques have been described to date: total or partial turbinectomy, submucosal resection (surgical or with a microdebrider), with turbinate outfracture being some of those. Objective: In this study, we compared the pre- and postoperative lower turbinate volumes using computed tomography in patients who had undergone septoplasty and compensatory lower turbinate turbinoplasty with those treated with outfracture and bipolar cauterization. Methods: This retrospective study enrolled 66 patients (37 men, 29 women) who were admitted to our otorhinolaryngology clinic between 2010 and 2017 because of nasal obstruction and who were operated on for nasal septum deviation. The patients who underwent turbinoplasty due to compensatory lower turbinate hypertrophy were the turbinoplasty group; Outfracture and bipolar cauterization were separated as the out fracture group. Compensatory lower turbinate volumes of all patients participating in the study (mean age 34.0 ± 12.4 years, range 17-61 years) were assessed by preoperative and postoperative 2 month coronal and axial plane paranasal computed tomography. Results: The transverse and longitudinal dimensions of the postoperative turbinoplasty group were significantly lower than those of the out-fracture group (p = 0.004). In both groups the lower turbinate volumes were significantly decreased (p = 0.002, p < 0.001 in order). The postoperative volume of the turbinate on the deviated side of the patients was significantly increased: tubinoplasty group (p = 0.033). Conclusion: Both turbinoplasty and outfracture are effective volume-reduction techniques. However, the turbinoplasty method results in more reduction of the lower turbinate volume than outfracture and bipolar cauterization.

Resumo Introdução: A causa mais comum de falha da septoplastia é a hipertrofia das conchas inferiores não tratada adequadamente. Diversas técnicas foram descritas até o momento: turbinectomia total ou parcial, ressecção da submucosa (cirúrgica ou com microdebridador) e a fratura lateral. Objetivo: Neste estudo, comparamos os volumes pré e pós-operatório da concha inferior com hipertrofia compensatória com o uso de tomografia computadorizada entre pacientes submetidos a septoplastia e turbinoplastia ou fratura lateral com cauterização bipolar. Método: Este estudo retrospectivo incluiu 66 pacientes (37 homens e 29 mulheres) internados em nosso serviço de otorrinolaringologia entre 2010 e 2017 por obstrução nasal e submetidos à cirurgia por desvio de septo nasal. Os pacientes submetidos à turbinoplastia devido à hiperplasia compensatória da concha inferior formaram o grupo turbinoplastia; aqueles submetidos à fratura lateral e cauterização bipolar foram separados, formaram o grupo fratura lateral. Os volumes compensatórios da concha inferior de todos os pacientes que participaram do estudo (idade média de 34,0 ± 12,4 anos, faixa de 17 a 61 anos) foram avaliados por tomografia computadorizada dos seios paranasais nos planos axial e coronal no pré-operatório e aos dois meses do pós-operatório. Resultados: As dimensões transversais e longitudinais do grupo turbinoplastia no pós-operatório foram significantemente menores do que as do grupo de fratura lateral (p = 0,004). Em ambos os grupos, os volumes da concha inferior diminuíram significantemente (p = 0,002, p < 0,001, respectivamente). O volume pós-operatório da concha do lado do desvio aumentou significantemente no grupo turbinoplastia (p = 0,033). Conclusão: Tanto a turbinoplastia como a fratura lateral são técnicas efetivas de redução de volume. No entanto, a turbinoplastia causa maior redução do volume da concha inferior do que a fratura lateral com cauterização bipolar.

Cutting the Holy Dome: The Evolution of Vertical Alar Resection.

INTRODUCTION: Dome division or vertical dome division (VDD) is a tip plasty technique that is effective when applied appropriately to suitable patients. For 15 years, we have used VDD and made modifications as needed. In classical VDD, the dome area is cut and left to heal, but experience shows that additional components are needed to complement dome division, such as sutures or grafts. In this study, we retrospectively analysed our rhinoplasty patients in whom we used vertical alar resection (VAR) to assess the advantages and disadvantages of this technique. To our knowledge, this is one of the most exhaustive studies of VDD, including over 3000 patients. MATERIALS AND METHODS: This retrospective case series reviewed the charts of 3965 patients who underwent VAR between 2000 and 2015. All patients were operated on by the senior surgeon. Dome division was used for various reasons, including a deformed tip area in revision rhinoplasties, droopy nose, wide tip, pinched nose, tip asymmetry, and overprojected nasal tip. Patients were excluded if they had septal deviation that enabled tip rotation, or a dorsum problem that caused tip asymmetry. RESULTS: The study included 3965 patients (3172 women and 793 men) who underwent open rhinoplasty from 2000 to 2015. The mean patient age was 28.3 years (range 18-50 years). The mean clinical follow-up duration was 11.2 years. CONCLUSION: In conclusion, this technique is capable of modifying all parameters of the nasal tip (projection, rotation, and volume), as required, at the same time, addressing many tip problems.

Association of Autologous Costal Cartilage Harvesting Technique With Donor-Site Pain in Patients Undergoing Rhinoplasty.

IMPORTANCE: Postoperative pain at the donor site is a common morbidity following autologous costal cartilage grafting. OBJECTIVE: To evaluate postoperative pain at the donor site after the use of a muscle-sparing costal cartilage harvesting technique compared with a muscle-cutting technique using electrocautery. DESIGN, SETTING, AND PARTICIPANTS: Designed as a controlled trial without randomization, this prospective, comparative cohort study was conducted between January 1, 2016, and March 31, 2017. Participants included 20 patients who underwent rhinoplasty for various cosmetic and functional complaints from January 1, 2016, to February 28, 2017. Of the 20 patients, 1 was excluded owing to an infection that developed on postoperative day (POD) 7. Patients were grouped by the rib harvesting technique used that was either a muscle-sparing technique (n = 11) or a muscle-cutting technique (n = 8). Skin incisions for both groups were carried out with a blade. Transection of muscle fascia and muscle fibers was performed with monopolar electrocautery in the muscle-cutting technique group. Blunt dissection with a hemostat was performed in the muscle-sparing technique group. All other surgical techniques were identical. MAIN OUTCOMES AND MEASURES: Postoperative pain was assessed with visual analog scale scores for resting pain and movement pain. Eight pain measurements were noted at the sixth postoperative hour and on PODs 1, 2, 3, 7, 15, 30, and 45. During the hospital stay, the postoperative need for analgesics was recorded daily as the number of analgesic infusion vials used. RESULTS: The 19 patients in the study included 11 women and 8 men whose mean age (SD) was 33.2 (10.3) years The mean (SD) visual pain analog scale scores for resting pain and movement pain were consistently higher in the muscle-cutting technique group than in the muscle-sparing technique group. This difference was statistically significant on PODs 2, 3, and 15 for resting pain and on PODs 2, 3, 7, 15, 30, and 45 for movement pain. The mean postoperative need for analgesic infusion vials during hospital stay was higher in the muscle-cutting technique group, and the difference was statistically significant on POD 2 (1.9 [0.6] vials vs 1.0 [0.9] vials; P = .02). CONCLUSIONS AND RELEVANCE: Both resting and movement pain at the donor site was significantly reduced in the muscle-sparing technique group during the postoperative period, findings that align with anecdotal reports in the literature. Routine use of the muscle-sparing technique in autologous costal cartilage harvesting is recommended to reduce postoperative pain. LEVEL OF EVIDENCE: 2.

Are people who have a better smell sense, more affected from satiation? / As pessoas que têm melhor olfato são mais afetadas pela saciedade?

Abstract Introduction: The olfactory system is affected by the nutritional balance and chemical state of the body, serving as an internal sensor. All bodily functions are affected by energy loss, including olfaction; hunger can alter odour perception. Objective: In this study, we investigated the effect of fasting on olfactory perception in humans, and also assessed perceptual changes during satiation. Methods: The "Sniffin' Sticks" olfactory test was applied after 16 h of fasting, and again at least 1 h after Ramadan supper during periods of satiation. All participants were informed about the study procedure and provided informed consent. The study protocol was approved by the local Ethics Committee of Gaziosmanpaşa Taksim Education and Research Hospital (09/07/2014 no: 60). The study was conducted in accordance with the basic principles of the Declaration of Helsinki. Results: This prospective study included 48 subjects (20 males, 28 females) with a mean age of 33.6 ± 9.7 (range 20-72) years; their mean height was 169.1 ± 7.6 (range 150.0-185.0) cm, mean weight was 71.2 ± 17.6 (range 50.0-85.0) kg, and average BMI was 24.8 ± 5.3 (range 19.5-55.9). Scores were higher on all items pertaining to olfactory identification, thresholds and discrimination during fasting vs. satiation (p < 0.05). Identification (I) results: Identification scores were significantly higher during the fasting (median = 14.0) vs. satiation period (median = 13.0). Threshold (T) results: Threshold scores were significantly higher during the fasting (median = 7.3) vs. satiation period (median = 6.2). Discrimination (D) results: Discrimination scores were significantly higher during the fasting (median = 14.0) vs. satiation period (median = 13.0). The total TDI scores were 35.2 (fasting) vs. 32.6 (satiation). When we compared fasting threshold value of >9 and ≤9, the gap between the fasting and satiety thresholds was significantly greater in >9 (p < 0.05). Conclusion: Olfactory function improved during fasting and declined during satiation. The olfactory system is more sensitive, and more reactive to odours, under starvation conditions, and is characterised by reduced activity during satiation. This situation was more pronounced in patients with a better sense of smell. Olfaction-related neurotransmitters should be the target of further study.

Resumo Introdução: O sistema olfatório é afetado pelo equilíbrio nutricional e estado químico do corpo, que serve como um sensor interno. Todas as funções corporais são afetadas pela perda de energia, inclusive o olfato; a fome pode alterar a percepção do odor. Objetivo: Neste estudo, investigamos o efeito do jejum sobre a percepção olfativa em seres humanos, e também avaliamos as mudanças de percepção durante a saciedade. Método: O teste olfatório Sniffin Sticks foi aplicado após 16 horas de jejum e novamente pelo menos 1 hora após a ceia do Ramadã durante os períodos de saciedade. Todos os participantes foram informados sobre os procedimentos do estudo e forneceram o consentimento informado. O protocolo do estudo foi aprovado pelo Comitê de Ética do Gaziosmanpaşa Taksim Education e Research Hospital (2014/09/07 n° 60). O estudo foi conduzido de acordo com os princípios básicos da Declaração de Helsinki. Resultados: Foram incluídos 48 pacientes (20 homens, 28 mulheres) com média de 33,6 ± 9,7 aos (variação 20-72); a altura média deles era de 169,1 ± 7,6 cm (variação 150-185), o peso médio era de 71,2 ± 17,6 kg (variação de 50-85) e o IMC médio era de 24,8 ± 5,3 (variação de 19,5-55,9). Os escores foram maiores em todos os itens correspondentes à identificação olfativa, limiares e discriminação durante jejum vs. saciedade (p < 0,05). Resultados da identificação (I): os escores de identificação foram significativamente maiores durante o jejum (mediana = 14) vs. período de saciedade (mediana = 13). Resultados limiares (T): os escores limiares foram significativamente maiores durante o jejum (mediana = 7,3) vs. período de saciedade (mediana = 6,2). Resultados de discriminação (D): os escores de discriminação foram significativamente maiores durante o jejum (mediana = 14) vs. período de saciedade (mediana = 13). Os escores totais de TDI foram de 35,2 (jejum) vs. 32,6 (saciedade). Quando comparamos o valor do limiar de jejum de > 9 e ≤ 9, a diferença entre os limiares de jejum e de saciedade foi significativamente maior em > 9 (p < 0,05). Conclusão: A função olfatória melhorou durante o jejum e diminuiu durante a saciedade. O sistema olfatório é mais sensível e mais reativo aos odores em condições de fome e é caracterizado por atividade reduzida durante a saciedade. Essa situação foi mais pronunciada em pacientes com um melhor sentido olfativo. Os neurotransmissores relacionados com o olfato devem ser alvo de um estudo mais aprofundado.

An Effective Technique for Nasal Radix Reduction in Septorhinoplasty: Procerus Muscle Resection.

In rhinoplasty patients radix position profoundly impacts the appearance of the nasal profile by influencing dorsal length, contour, angulation, and height. The authors wanted to introduce a new perspective to radix, and decided to focus on subcutaneous tissues, especially procerus muscle. Actually resection of procerus and corrugator supercilii is a part of browlift and endoscopic facelift techniques, with which the authors are already familiar.In this short report and video, the authors wanted to present a new technique to lower radix area. This technique is based on face anatomy, and muscles under radix area, and takes its roots from facelift techniques. Before introducing the authors' technique the authors wanted to show the effect of soft tissues on radix with lateral nasal x-rays. With this maneuver the soft tissue thickness of radix area is thinned.

Osmophobia and olfactory functions in patients with migraine.

Olfactory dysfunction and migraine has been associated for a long time. In this study, we planned to compare olfactory functions in patients with migraine and osmophobia with patients having migraine but no osmophobia, in addition with a normal control group using "Sniffin' Sticks" test. The main distinction of this study is that all qualitative and quantitative properties of olfactory functions; threshold, discrimination and identification, are evaluated separately and jointly. Thirty healthy person aged between 16 and 56 (18 women, 12 men) and 60 migraine patients aged between 15 and 54 (39 women, 21 man) were included in the study. All patients have been inquired about osmophobia and have been assessed with Hedonic tone assessment. Osmophobia has been tested for perfume, cigarette smoke, leather, stale food, soy sauce, fish, spices and coffee smells. Olfactory functions has been assessed with "Sniffin' Sticks" smell test. Thresholds, discrimination and identification have been determined for each patient. In migraine patients with osmophobia, threshold was 7.75 ± 2.3, in migraine patients without osmophobia threshold was 8.25 ± 1.5 and threshold was 10.75 ± 1.3 for the control group. Discrimination score was 6 ± 1.2 in migraine patients with osmophobia, 9 ± 0.8 in patients without osmophobia and was 12 ± 1.4 in the control group. In migraine patient with or without osmophobia Threshold/Discrimination/Identification (TDI) scores were lower than the control group. The most important parameter in our study is that discrimination scores were especially lower in patients with osmophobia. We believe that this decrease in discrimination in migraine patients with osmophobia; who claim that they smell everything and they are sensitive to all smells, is significant. Further studies about smell discrimination will help better understand some conditions; especially anosmia and hyposmia after upper respiratory tract infections and parosmia.

The Effect of Nystatin Solution on Otoacoustic Emissions in Rats.

OBJECTIVE: In patients with a perforated tympanic membrane, topically administered medication reaches the middle ear and thus creates a risk of ototoxicity. The aim of the present study was to evaluate the possible ototoxic effect of the antifungal medication nystatin when administered to the rat middle ear cavity. MATERIALS AND METHODS: Three groups (negative control, positive control, and study groups), each containing eight rats, were formed. Before the drug administration, distortion product otoacoustic emissions were recorded in both ears of each rat. Saline (0.09% NaCl), gentamycin, and nystatin solutions were transtympanically injected into the middle ear cavities of the negative control, positive control, and study groups, respectively, for five consecutive days. Seven days after the last infiltration, the control otoacoustic emission was measured, and the data of the 2, 3, 4, 6, 8 kHz frequencies were statistically analyzed. RESULTS: There were no significant changes between the 1st and 2nd measures in the negative control group (0.09% NaCl) (p>0.05), whereas there were significant changes between the 1st and 2nd measures in the positive control group (gentamycin) and study group (nystatin) (p<0.05). CONCLUSION: Ototopical medications carry a risk of ototoxicity in patients with perforated ear drums. In the present study, it was shown that nystatin, an antifungal that can be ototopically used in the treatment of otomycosis, may cause a decrease in otoacoustic emissions in rats when administered into the middle ear cavities.

An objective assessment of halitosis in children with adenoid vegetation during pre- and post-operative period.

OBJECTIVES: Although most specialists in otorhinolaryngology and pediatrics find halitosis to be a common problem in children with adenoid hypertrophy, there are no objective data on this topic in the literature. Whether adenoid hypertrophy is a risk factor for halitosis or whether halitosis is a sign of adenoid hypertrophy remains unclear. Thus, the aim of this study was to investigate whether children diagnosed with adenoid hypertrophy have a higher probability of halitosis than do children in the normal population and whether adenoidectomy can decrease oral malodor. METHODS: Forty children with adenoid hypertrophy and 40 healthy subjects aged 5-15 years were included in the study. The children with adenoid hypertrophy underwent adenoidectomy operations and were followed for 3 months. We measured volatile sulfur compounds (VSCs), hydrogen sulfide (H2S), methyl mercaptan (CH3SH), and dimethyl sulfide (CH3)2S using an objective method, a portable gas chromatograph (OralChroma; AbiMedical, Osaka, Japan). RESULTS: The mean CH3SH and (CH3)2S levels were significantly different (p < 0.05) between the adenoid hypertrophy group and the controls. The H2S, CH3SH, and (CH3)2S levels in the third postoperative month were significantly lower (p < 0.05) than those in the preoperative period, and there was no significant difference postoperatively between the patients with adenoid hypertrophy and controls. There was a positive correlation between age and VSC levels, and CH3SH levels were significantly higher in patients with ventilation tube insertion, rather than just adenoidectomy. CONCLUSIONS: There was a statistically significant association between halitosis and adenoid hypertrophy, and a significant improvement in halitosis was obtained following adenoidectomy. The present study provides an association between halitosis and adenoid hypertrophy. If there is no other oral pathology causing halitosis, halitosis can be a sign of adenoid hypertrophy in children.

Does iron deficiency anemia affect olfactory function?

Conclusion This study found a negative effect of IDA on olfactory function. IDA leads to a reduction in olfactory function, and decreases in hemoglobin levels result in further reduction in olfactory function. Objective This study examined the effects of iron-deficiency anemia (IDA) on olfactory function. Method The study enrolled 50 IDA patients and 50 healthy subjects. Olfactory function was evaluated using the Sniffin' Sticks olfactory test. The diagnosis of IDA was made according to World Health Organization (WHO) criteria. Results Patients with IDA had a significantly lower threshold, discrimination, and identification (TDI) value, and a lower threshold compared with the control group. However, there were no significant differences between the groups in terms of smell selectivity values.

A Simple Technique to Avoid Restenosis for Dacryocystorhinostomy.

The most common reason for failure in dacryocystorhinostomy has been proven to be the granuloma or membranous obstruction of scar tissue formation on lacrimal opening in the nasal cavity during the healing process. In this article, the authors suggest an easy maneuver to avoid the risk of scarring and collapsing of the knot in bony window by using a piece of an aspiration catheter. Using this easy maneuver, the authors can manage to reduce the risk of scarring and stenosis, and when the authors take out the tubes after 2 months, removing the silicone tube was easier with our technique. Moreover with the present technique the authors observed there was no embedding of the knot in the scar.

Effects of Spreader Grafts on Olfactory Function in Septorhinoplasty.

BACKGROUND: Following rhinoplasty, the cross-sectional parts of the nose may be significantly reduced, and nasal air movement and olfaction may be altered. Studies on olfactory function after surgical procedures are quite limited and have largely focused on sinus surgery or septoplasty. OBJECTIVES: The objective of this study is to assess the consequences of spreader grafts on olfactory function. METHODS: This prospective study was conducted at the Gaziosmanpasa Taksim Education and Research Hospital, Department of Otolaryngology, from January 2014 to June 2015. In total, 68 patients who had undergone an open-technique septorhinoplasty were included. In 35 patients, bilateral spreader grafts were included with the open septorhinoplasty (group 1), and 33 patients underwent open septorhinoplasties without spreader grafts (group 2). RESULTS: The age and gender distributions of the patients in the two groups did not differ (p > 0.05). Preoperative threshold, discrimination, and identification values in both groups did not differ (p > 0.05). In groups 1 and 2, postoperative threshold values were significantly higher than preoperative values (p < 0.05). The change in threshold, discrimination, and identification level was significantly higher postoperatively versus preoperatively in group 1 (p < 0.05); however, the changes in discrimination and identification values did not significantly differ between in group 2 (p > 0.05). CONCLUSIONS: Our study demonstrates the superior widening effect of spreader grafts over the nasal valve and favorable results in olfactory function in primary septorhinoplasty patients.

Sudden hearing loss due to oxaliplatin use in a patient with colon cancer.

Oxaliplatin is used to treat advanced colorectal cancer. Platinum-containing chemotherapeutic agents are known to be ototoxic. However, ototoxicity is rare with newer generation platinum-derived agents, such as oxaliplatin. This case report presents a rare case of sudden unilateral sensorineural hearing loss following intravenous (IV) infusion of oxaliplatin in a 64-year-old woman with advanced colon cancer. The hearing loss was severe and did not respond to treatment. To the best of our knowledge, this is the fifth reported case of oxaliplatin ototoxicity. Although oxaliplatin ototoxicity is rare, physicians must be aware of this important adverse effect, and an audiometric evaluation must be performed when necessary. Patients treated with oxaliplatin should be followed closely for early signs and symptoms of hearing loss, and if hearing loss is detected, treatment should be stopped immediately.
