Analysis of patient- and procedure-related risk factors for nasal septal perforations following septoplasty.

OBJECTIVES: To assess the possible relationship between various predictive factors (patient or surgery related) and the development of nasal septal perforations (NSP) with the help of a large study group. METHODS: One hundred and forty-three patients were included in the study. The presence of the following factors was evaluated and compared between the NSP and healthy group: types of surgeries, presence of unilateral or bilateral mucosal tears, concomitant inferior turbinate interventions, smoking, accompanying diabetes mellitus (DM) or allergic rhinitis (AR), types of nasal packings, duration of the surgery (minutes), and the experience of the surgeon (senior/junior). Nasal septal deviations were grouped into two: simple cartilage crests at the septum base and other-more complicated-deviations. RESULTS: NSP was detected in six (4.2%) patients after a mean follow-up of 9.3 ± 3.7 (min: 6 max: 14) months. None of these patients suffered from (AR) or DM. Four of these patients had unilateral and one patient had bilateral mucosal tears during the surgeries. None of the above-mentioned factors-including mucosal tears, type of the deviation or experience of the surgeon-had a significant effect on NSP. CONCLUSION: Untreated bilateral corresponding mucosal tears are the main cause of NSP. When immediately repaired, unilateral or bilateral tears do not affect the development of NSP significantly. Patient-related factors such as age, DM, smoking, AR, and procedure-related factors such as duration, the complexity of the septal deviation, type of the nasal packing, and experience of the surgeon also do not have a significant effect on NSP.

Is topical fluorescein that effective in endoscopic CSF leak closure?

PURPOSE: Several diagnostic modalities are used to detect CSF leaks. Intraoperative use of intrathecal fluorescein can help to detect and localize a CSF leak simultaneously. However, it is not FDA approved, the application is invasive and has serious complications. Topical fluorescein is reported to be a safe and sensitive alternative to ITF. In this study, we aimed to evaluate the effectiveness of topical fluorescein in CSF leak closure. METHODS: This retrospective study includes 27 consecutive patients (19 women, 8 men) who underwent endoscopic endonasal CSF leak closure using topical fluorescein, between 2011 and 2017. RESULTS: In two patients, radiologic studies false positively locate the defect. ß2 transferrin and topical fluorescein tests were positive in these patients. Both cases needed a second operation. CONCLUSION: If radiologic studies fail to locate the defect properly, topical fluorescein only confirms the CSF leak, but the defect cannot be located anatomically intraoperatively.

Management of thyroid gland invasion in laryngeal and hypopharyngeal squamous cell carcinoma.

The objective of this study was to determine the incidence of thyroid gland invasion in laryngeal and hypopharyngeal squamous cell carcinoma; and the association between clinicopathological parameters and thyroid gland invasion. Medical records of 75 patients with laryngeal and hypopharyngeal squamous cell carcinoma who underwent total laryngectomy with thyroidectomy were reviewed, retrospectively. Preoperative computed tomography scans, clinical and operative findings, and histopathological data of the specimens were evaluated. There were 73 male and two female patients with an age range of 41-88 years (mean 60.4 years). Hemithyroidectomy was performed in 62 (82.7 %) and total thyroidectomy was performed in 13 patients (17.3 %). Four patients had histopathologically proven thyroid gland invasion (5.3 %). In three patients, thyroid gland involvement was by means of direct invasion. Thyroid gland invasion was significantly correlated with thyroid cartilage invasion. Therefore, prophylactic thyroidectomy should not be a part of the treatment policy for these tumors.

A new method of identifying the posterior inferior nasal nerve: implications for posterior nasal neurectomy.

INTRODUCTION: Posterior nasal neurectomy is an effective way of treating recalcitrant rhinitis. The aim of this study is to describe the anatomic relationship between the posterior inferior nasal nerve (PINN) and the structures that might be important for posterior nasal neurectomy. MATERIALS AND METHODS: An anatomic study was conducted in a university hospital dissection laboratory with 15 formalin-fixed, sagittally cut adult cadaver heads. The distance between PINN and (1) nasal sill, (2) maxillary sinus ostium, (3) posterior fontanel, (4) torus tubarius, and (5) crista ethmoidalis was measured and the location of PINN with respect to the sphenopalatine artery was assessed to define the exact location of PINN. RESULTS: The mean distance between PINN and nasal sill (56.4 mm), maxillary sinus ostium (27 mm), posterior fontanel (12.5 mm), torus tubarius (13 mm), and crista ethmoidalis (8 mm) was determined. PINN was found consistently posterior to the sphenopalatine artery where the inferior turbinate attaches to the lateral nasal wall. CONCLUSION: Instead of finding PINN around the sphenopalatine foramen, PINN can be located more easily posterior to the sphenopalatine artery where the inferior turbinate attaches to the lateral nasal wall without cauterizing the sphenopalatine artery.

Chicken or the egg: the dilemma of allergic rhinitis versus adenoid hypertrophy.

BACKGROUND: There is no consensus as to whether allergic rhinitis (AR) is a cause of adenoid hypertrophy (AH). This study evaluated the role of allergy in AH, and it explored the role of nasal endoscopy and the history of diagnosing AR in children empirically. MATERIALS AND METHODS: This study enrolled 155 children consecutively in Izmir Behcet Uz Children`s Hospital between January and September 2013. RESULTS: Of the patients, 101 (65.2%) had a positive skin prick test. Multiple allergen sensitivity was identified in 76 (75.2%) of these patients. The history items of itching and sneezing had predictive value for empirically diagnosing AR in children. Of the nasal examination findings, only the nasal secretion characteristics had significant predictive value. AH and AR had a significant negative correlation. CONCLUSION: In this study, AH and AR were inversely related. The characteristics of the nasal secretions, itching, sneezing, were predictors of AR in children.

Searching for the cheese: does ethmoid pneumatization affect the location of the anterior ethmoid artery?

Endoscopic sinus surgery is a widely used technique in otolaryngologic practice. To avoid complications, the locations of important anatomical structures, such as the anterior ethmoid artery (AEA), should be determined preoperatively. We want to evaluate the effect of ethmoid cavity pneumatization on the location of the AEA and to determine consistent landmark(s) for locating the AEA. 524 consecutive patients undergoing sinus CT scans between February and October 2012 were reviewed retrospectively. After the exclusion criteria were applied, 150 CT scans (300 sides) were selected for the study. A statistically significant positive correlation was found between ethmoid pneumatization and the distance of the AEA to the attachment of the inferior turbinate to the lateral nasal wall (Spearman's rho = 0.305; p < 0.001). Likewise, a statistically significant positive correlation was found between ethmoid pneumatization and the distance between the AEA and the frontonasal junction (Spearman's rho = 0.219; p < 0.001). We found that the artery was located mostly between the second and third lamellae [n 211 (71 %) cases]. There was no statistically significant correlation between ethmoid pneumatization and AEA location in terms of the lamellae. Increased ethmoid volume increases the distance of the AEA from the frontonasal junction and the lateral attachment of the inferior turbinate. However, increased pneumatization of the ethmoid cavity did not affect AEA localization in terms of the lamellae. Based on our findings, we suggest that using the lamellae to locate the AEA is reliable.

Factors confusing the diagnosis of laryngopharyngeal reflux: the role of allergic rhinitis and inter-rater variability of laryngeal findings.

The objective of the study was to determine the inter-rater variability in assessment of laryngeal findings and whether diagnosing laryngopharyngeal reflux based on the laryngeal findings and history alone without considering allergic rhinitis leads to the overdiagnosis and overtreatment of laryngopharyngeal reflux. Patients with positive and negative skin prick tests were recruited from an allergy clinic in a tertiary teaching university hospital. All subjects completed the Reflux Symptom Index (RSI) and underwent laryngeal examinations by three physicians blinded to the skin prick test results and the Reflux Finding Score (RFS) was determined. RFS >7 or RSI >13 was considered reflux positive. Fleiss' kappa (κ) was used to measure inter-rater agreement. The inter-rater agreement was low for pseudosulcus vocalis (κ = 0.078), ventricular obliteration (κ = 0.206), diffuse laryngeal edema (κ = 0.204), and posterior laryngeal hypertrophy (κ = 0.27), intermediate for laryngeal erythema/hyperemia (κ = 0.42) and vocal fold edema (κ = 0.42), and high for thick endolaryngeal mucus (κ = 0.61). Although the frequency of allergy was high, there was no significant difference between allergy-positive and laryngopharyngeal reflux-positive patients. On logistic regression analysis, thick endolaryngeal mucus was a significant predictor of allergy (p = 0.012, odds ratio 0.264, 95 % confidence interval 0.093-0.74). The laryngeal examination for reflux is subject to marked inter-rater variability and allergic laryngitis was not misdiagnosed as laryngopharyngeal reflux. The presence of thick endolaryngeal mucus should alert physicians to the possibility of allergic rhinitis/laryngitis.

A rare complication of septoplasty: tension pneumocephalus without rhinorrhea.

This paper describes a tension pneumocephalus without cerebrospinal fluid leak, a rare complication of septoplasty. We present a case of tension pneumocephalus without cerebrospinal fluid leak 1 month after a septoplasty operation. Although endoscopic sinus surgery can be utilized for repair of the defect, intracranially displaced ethmoid bone fragment makes an open approach more feasible. His postoperative course was uneventful and postoperative CT scan revealed no signs of pneumocephalus. Absence of cerebrospinal fluid leak made this case unique in presentation and caused a delay in diagnosis. Severe headache after septoplasty should alert the surgeon to investigate possible intracranial complications.

Results of decompression with middle cranial fossa approach or traumatic intratemporal fascial nerve injury.

OBJECTIVE: To present the results of the traumatic intratemporal facial nerve injury that have undergone facial nerve decompression by using middle cranial fossa (MCF) approach. STUDY DESIGN: A retrospective study SETTING: Tertiary referral center PATIENTS AND METHODS: In this study, 13 patients who developed facial paralysis due to temporal bone trauma and undergone decompression by using MCF approach in Department of Otorhinolaryngology of Izmir Katip Celebi University Research and Training Hospital between January 1993 and December 2012 were presented retrospectively. Patients were assessed in terms of side, etiology, fracture type, House-Brackmann (HB) grade, electroneuronography (ENOG), electromyography (EMG), hearing loss, operation time, and the region of the injury. RESULTS: The fracture was at the right side in 7 (53.8%) and at the left side in 6 patients (46.1%). The type of temporal bone fracture was longitudinal in 6 (46.1%), transverse in 2 (15.3%), and mixed in 5 patients (38.4%). Total axonal degeneration in EMG and ENOG were seen in all patients, who were HB grade 6 at preoperative assessment. Mean operation time was 30 days. The lesion in all patients was at the region of geniculate ganglion. There was conductive hearing loss in 7 patients (53.8%), sensorineural in 4 (30.7%), and mixed in 1 patient (7.6%); hearing was normal in 1 patient (7.6%). Seven patients (53.8%) improved to HB grade 2. CONCLUSION: In the light of the information obtained from HRCT, ENOG, and EMG, we believe that better results can be achieved with facial nerve decompression that is performed before 1 month, and geniculate ganglion region may be better controlled by MCF approach.

Isolated tympanic plate fracture frequency and its relationship to mandibular trauma.

PURPOSE: This study evaluated the prevalence of isolated tympanic fractures and their correlation with mandibular fractures by using maxillofacial computed tomography (CT). MATERIALS AND METHODS: We retrospectively evaluated the maxillofacial CT of 1590 patients who presented to our emergency department with maxillofacial trauma between December 2010 and December 2012. Maxillofacial CT was used as the criterion standard for evaluating patients with maxillofacial fractures. The CT images were evaluated by using an electronic picture archiving and communications system and interpreted independently by 2 radiologists. RESULTS: The maxillofacial CT images revealed mandibular fractures in 167 of the patients and isolated tympanic plate fractures in 35 of these 167 patients. Four patients (11%) had a bilateral tympanic plate fracture, and 31 patients (89%) had unilateral tympanic plate fracture. Of all the tympanic plate fractures, 19 (54%) were on the right side and 16 (46%) were on the left side (P > .05). In our results, a significant correlation between the presence of a right-sided tympanic plate fracture and fracture of the ipsilateral condylar process was found (P = .036). However, a statistically significant difference between the presence of a tympanic plate fracture and other mandible fractures, additional soft-tissue findings, or the number of fractures was not determined (P > .05). Sex had no impact on the presence of tympanic plate fracture (P > .05). CONCLUSION: The frequency of isolated tympanic plate fractures in maxillofacial trauma is low, but it is an important anatomic location. Condyle fractures are significantly associated with isolated tympanic plate fractures. The presence of these injuries should raise suspicion of a concomitant isolated tympanic plate fracture.

Postintubation laryngotracheal stenosis: assessing the success of surgery.

OBJECTIVE: This study evaluated the outcome in adult patients with laryngotracheal stenosis (LTS) and assessed the effect of procedures on their quality-of-life scores. METHODS: The study included 15 adult patients with LTS (11 males [73.3%], 4 females [26.7%]; mean age, 32 years [range, 10-52 years]) treated at the Department of Otolaryngology Head and Surgery Clinic, Izmir Atatürk Research Hospital, Turkey, from 1997 to 2008. Success of the surgery is evaluated by decanullation rate, Short form-36 (SF-36), and the Medical Research Council dyspnea scale. RESULTS: The etiology of the LTS was intubation related in 14 cases (93.3%) and idiopathic in 1 case. According to the Myers-Cotton classification, 2 (13%), 8 (54%), and 5 (33%) patients were at stages 2 to 4, respectively. Fourteen patients had a mean follow-up of 57 months (range, 24-256 months). The stenotic segment involved 1 to 3 cm (mean, 1.7 cm) of trachea, and 2 to 5 tracheal rings (mean, 3.1) were resected. Postoperative decannulation was achieved in 13 patients (86.6%). In the short form-36 questionnaire, all of the parameters except for "role-emotional" were found to be significant (P < 0.01). The Medical Research Council dyspnea scale assessment revealed a significant (P < 0.001) decrease postoperatively. CONCLUSIONS: Segmental resection with primary anastomosis is an effective method and can be used as the first option in selected cases of advanced stenosis.

[Our endoscopic transcanalicular multidiode laser dacryocystorhinostomy results through bicanalicular silicone tube intubation]. / Bikanaliküler silikon tüp entübasyonu ile endoskopik transkanaliküler multidiod lazer dakriyosistorinostomi sonuçlarimiz.

OBJECTIVES: This study aims to evaluate the results of transcanalicular multidiode laser dacryocystorhinostomy (TMDL-DCR) through bicanalicular silicone tube intubation (BSTI). PATIENTS AND METHODS: Between September 2011 and March 2012, treatment-naïve 43 eyes of 43 patients (24 males, 19 females; mean age 53.6±4.1 years; range 37 to 69 years) who presented with the complaint of watery eyes with a nasolacrimal duct obstruction and underwent TMDL-DCR through endoscopic silicone tube were included. Patients were assessed postoperatively. During follow-up, changes from baseline in signs and symptoms and the duration of intubation were recorded. RESULTS: The mean age of the patients was 53.6 years (range, 37 to 69 years). The mean follow-up was 19.4±2.2 months (range, 18 to 23 months). The mean duration of surgery was 16.5 min (range, 11 to 32 min). Epiphora was seen in seven patients following surgery. Nasolacrimal duct was open in 36 patients. The success rate was 83.7%. CONCLUSION: Transcanalicular multidiode laser DCR through BSTE is an effective and safe method in the management of nasolacrimal stenosis.

Multivariate analysis of clinical and radiological risk factors for revision endoscopic sinus surgery in patients with chronic rhinosinusitis with nasal polyps: can phenotype predict recurrence?

OBJECTIVE: This study aimed to analyse clinical and radiological features (phenotypes) to predict revision risk after functional endoscopic sinus surgery in patients with chronic rhinosinusitis with nasal polyps. METHOD: Phenotype characteristics of the patients with chronic rhinosinusitis with nasal polyps who underwent functional endoscopic sinus surgery were analysed retrospectively. RESULTS: The rates of asthma, aspirin sensitivity, smoking and a positive prick test result were significantly higher in revision functional endoscopic sinus surgery cases (p < 0.001, 0.001, < 0.001 and < 0.001, respectively). Multivariate analysis demonstrated that only gender, pre-operative nasal steroid use, pre-operative systemic steroid use, intra-operative systemic steroid use and smoking were significant risk factors for revision functional endoscopic sinus surgery (p = 0.034, 0.001, 0.010, 0.007 and 0.001, respectively). In addition, only eosinophilia and aspirin sensitivity were significant risk factors for multiple revision functional endoscopic sinus surgery procedures (p = 0.043 and 0.005, odds ratio = 2.4 and 5.2). CONCLUSION: Beyond the endotype of chronic rhinosinusitis with nasal polyps, defining clinical and radiological factors enables a valid prediction of patients at high risk of revision functional endoscopic sinus surgery.

High PI3K/mTOR and low MAPK/JNK activity results in decreased apoptosis and autophagy in nasal polyposis.

INTRODUCTION: Nasal polyposis is a progressive inflammatory disease that reduces the quality of life. The role of apoptotic and autophagic pathways in nasal polyposis pathogenesis is not yet clearly known. OBJECTIVE: In this study we aimed to investigate apoptotic (MAPK/JNK), anti-apoptotic (PI3K/mTOR) and autophagic (LC3) pathways which are related each other in the nasal polyposis tissues. METHODS: Twenty patients with nasal polyps and fifteen patients going through an inferior turbinate reduction were included in this study. Patients with asthma, Samter triad and allergic fungal sinusitis were excluded from the study. The apoptotic and autophagic pathways were investigated in paraffin-embedded nasal tissue sections of 20 NP and 15 samples from inferior turbinate reduction by H&E and immunohistochemistry with h-score. TUNEL method with apoptotic index was used to demonstrate apoptotic cells. RESULTS: Decreased immunoreactivity of P38 MAPK (p < 0.005) and JNK (p < 0.005) were observed in nasal polyposis compared to material from inferior turbinate reduction. This decrease may indicate a downregulation of apoptosis as demonstrated by decreased TUNEL staining in nasal polyposis (p < 0.005). The PI3K (p < 0.002) and mTOR (p < 0.005) immunoreactivities were increased in nasal polyposis. This increase indicates a downregulation of autophagy as demonstrated by decreased LC3 staining in nasal polyposis (p < 0.001). CONCLUSION: Deficient apoptosis and autophagy through MAPK/JNK and PI3K/mTOR pathways may have a role in the pathogenesis of nasal polyposis.

Does Nasal Secretion Decrease in Sjögren Syndrome and Does This Affect Nasal Function?

OBJECTIVE: Sjögren syndrome is a systemic inflammatory disease causing gland dysfunction. Few (and contradictory) reports on the mucosal effects of Sjögren syndrome have appeared. Here, we objectively demonstrate nasal dryness in Sjögren syndrome patients and explore the effect of such dryness on olfaction. METHODS: Thirty-four consecutive patients with primary Sjögren syndrome were enrolled in this cross-sectional study. The control group consisted of 21 age- and sex-matched volunteers. Medical histories and nasal findings were recorded. The Connecticut Chemosensory Clinical Research Center test was used to evaluate olfactory function. All subjects underwent mucucociliary clearance analysis (the saccharin test and peak nasal inspiratory flowmetry). The intranasal Schirmer test was used to evaluate the nasal cavity. RESULTS: The nasal Schirmer test scores were 8.4 mm (right) and 8 mm (left) (P = .041, P = .016, respectively, compared to controls). The Chi-squared test revealed significant differences (compared to controls) in nasal dryness (P = .001), postnasal drip (P = .04), and smell (a decrease) (P = .005). Neither olfactory function nor mucociliary clearance differed between the groups. We noted a trend toward a positive correlation between olfactory function and the nasal Schirmer score but statistical significance was not attained. CONCLUSION: The intranasal Schirmer test objectively showed that Sjögren syndrome patients exhibited nasal cavity dryness; this is useful in terms of follow-up. This did not affect olfactory function. LEVEL OF EVIDENCE: 4 Laryngoscope, 131:370-373, 2021.

Turkish Guideline for Diagnosis and Treatment of Allergic Rhinitis (ART).

OBJECT: To prepare a national guideline for Otorhinolaryngologist who treat allergic rhinitis patients. METHODS: The study was conducted by three authors, namely the writing support team. The support team made the study plan, determined the writing instructions, chose the subgroups including the advisory committee, the advisors for authors and the authors. A workshop was organized at the very beginning to explain the details of the study to the team. Advisors took the chance to meet their coworkers in their subgroups and determined the main headings and subheadings of the guideline, together with the authors. After key words were determined by the authors, literature search was done in various databases. The authors keep in touch with the advisors and the advisors with the advisory committee and the support group at every stage of the study. National and International published articles as well as the abstracts of unpublished studies, imperatively presented in National Congresses, were included in this guideline. Only Guideline and meta-analyses published in last seven years (2013-2017) and randomized controlled studies published in last two years (2015-2017) were included. After all work was completed by the subgroups, support team brought all work together and edited the article. RESULTS: A detailed guideline about all aspects of allergic rhinitis was created. CONCLUSION: The authors believe that this guideline will enable a compact and up-to-date information on allergic rhinitis to healthcare professionals. This guideline is the first in the field of Otolaryngology in Turkey. It should be updated at regular intervals.

Akt and estrogen receptor expression in nasal polyps.

BACKGROUND: Nasal polyps (NP) is a common chronic inflammatory disease of the mucous membranes in the nose and paranasal sinuses. The underlying mechanisms of pathologic conditions to NP formation remains unclear. The aim of this study is to evaluate the expression of Akt and estrogen receptor (ER) in nasal polyps. MATERIAL AND METHODS: We respectively obtained 20 nasal polyp tissue and 15 concha from patients undergoing endoscopic polyp biopsy and turbinate resection. All samples were fixed in 10% formalin for 24 h and embedding in paraffin was using routine protocol for histological prepation. Sections 5 µm thick were cut and stained H&E. Tissue samples were stained with anti-ER and anti-Akt primary antibody, ER and Akt were evaluated immunohistochemically. There is a relationship between the estrogen receptor and PI3K/Akt signaling pathway in malignansy. In this study, it showed the effect of estrogen on the activation of Akt signaling pathway in nasal polyps. Mann- Whitney-U test was applied to evaluate the statistical differences between nasal polyp and control group, (P < 0.05) was accepted as significant. RESULTS: In H&E stained sections we observed a lot of inflamatory cells and eosinophils in the mucosa, submucosal connective tissue and around the glandular epithelium in nasal polyps. The mucosa and submucosal connective tissue was seen normally in control group in H&E stained. We determined that ER and Akt were intensely expressed in nasal polyps. Expression is localized especially in epithelial and glandular epithelium cells and submucosal connective tissue. In contrast, expression of ER and Akt were mildly expressed in turbinate resection samples. CONCLUSION: The expression of ER and Akt might be important factors in nasal polyp pathogenesis and may shed new light on clinical approaches in nasal polyp treatment.

Endoscopic-Powered Dacryocystorhinostomy Without Stenting: Long-term Outcomes of 120 Procedures.

Background The necessity of silicone stenting in endoscopic dacryocystorhinostomy (DCR) procedures is a controversial subject in the literature. Objective The purpose of the present study is to assess the long-term anatomical and functional outcomes of endoscopic-powered DCR (EP-DCR) without stenting or mucosal flaps. Methods One hundred twenty EP-DCR procedures were performed in 107 patients. Anatomical success was defined as a patent ostium on irrigation and functional success as free flow of dye from the ostium and resolution of epiphora. Results The mean follow-up was 46.5 months (range: 24-87). Of the 120 procedures, 13 were bilateral and 94 were unilateral. Anatomical and functional success rates of 92.5% were obtained. Conclusion EP-DCR without stenting is a safe and economic technique that provides satisfactory long-term results and could be considered as the treatment of choice for patients with postsaccal nasolacrimal duct obstruction.

Infrahyoid Flap, a Convenient Alternative for Reconstruction of Tongue and Floor of Mouth Defects: Case Series.

OBJECTIVE: The aim of this study was to share our clinical experience with the neurovascular myofasiocutan infrahyoid flap (NMIHF), which was used for the reconstruction of the defects after oral cavity cancer surgery. METHODS: Records of five patients who were diagnosed with oral cavity cancer and underwent tumor resection, neck dissection, and defect reconstruction with NMIHF between 2012 and 2017 were analyzed retrospectively. RESULTS: The infrahyoid flap was used in five patients: four males and one female. The mean age of patients was 61.8 years. Four patients underwent tumor resection and bilateral level I-III neck dissection, whereas one patient underwent tumor resection and unilateral level I-III neck dissection. NMIHF was used for the reconstruction of the defects during the same procedure in all the patients. Mean post-operative follow-up was 30.6 months. Partial skin necrosis was observed in two patients, but none of the patients showed total necrosis of the flap. Postoperatively, oral intake was initiated after an average of 12 days in all patients. For two patients who required post-operative radiotherapy (RT), the treatment was started after an average of 50 days. CONCLUSION: NMIHF does not prolong operation time and does not cause additional scar in the neck, and the defect in the donor field can be closed without the use of a graft or flap. This is considered to be a reliable and successful alternative to free flaps for the reconstruction of oral cavity defects.

Evidence of an association between mannose binding lectin codon 54 polymorphism and adenoidectomy and/or tonsillectomy in children.

Mannose binding lectin (MBL) is a calcium-dependent lectin that plays an important role innate immunity by activating the complement pathway. There have been a number of studies describing an association between the MBL genotype and disease susceptibility. MBL deficiency has been described as one of the factors leading to a number of infections in children with recurrent upper respiratory tractus infections (URTI). We hypothesized that MBL deficiency may be associated with recurrent URTI, which requires adenoidectomy and/or adenotonsillectomy. In this study to clarify this hypothesis we investigated whether there may be an association between two low producing MBL variants and adenoidectomy and/or tonsillectomy due to recurrent URTI in children. Blood samples were collected, adenoidectomy and/or tonsillectomy due to recurrent URTI and 50 controls (mean age 80.53 +/- 32.62 months). In all patients and controls codon 54 and codon 57 polymorphisms of the MBL gene were analyzed. None of the subjects from the patient group and control group carried codon 57 polymorphism of the MBL gene. The frequency of low-level MBL genotypes (AB and BB) for codon 54 polymorphism in the patient group was found to be significantly higher compared to the control subjects (55.7% versus 14%) (p<0.001). This study shows that the presence of low-level MBL alleles is associated with adenoidectomy and/or tonsillectomy caused by recurrent URTI in children.
