RESUMO
BACKGROUND: Encountering individuals sensitized to both inhalant and food allergens is challenging in clinical practice. Despite its rarity, studies have documented cross-sensitization between these allergens. However, the extent, diversity, and age-related variations of this phenomenon remain unclear. OBJECTIVE: Hence, our objective was to investigate a substantial quantity of allergy sensitivity test results in which both inhalant and food allergens were concurrently examined. The primary goal of our study is to calculate the cross-sensitization ratio, with a secondary objective of analyzing this phenomenon across four age groups. METHODS: A retrospective analysis was conducted on a multiple-antigen simultaneous test (MAST) obtained from a domestic laboratory medicine facility and comprising 55 food allergens and 49 inhalant allergens from 368,156 individuals aged 1 to 89. By calculating the cross-sensitization ratio, the degree of cross-sensitization between each food allergen and inhalant allergen was determined. Further subgroup analysis was conducted to ascertain the cross-sensitization ratio between the four subgroups categorized by age. RESULTS: The median cross-sensitization ratio between food and inhalant allergens was 5.14, indicating a significant level of cross-sensitization. The cross-sensitization ratio was greatest among pollen allergens and plant-derived food allergens, followed by between some animal aeroallergens and meat/fish/dairy/poultry food allergens. The degree of overall cross-sensitization was least prominent in adolescents, greater in adults and children, and most pronounced in the elderly. CONCLUSION: Our findings reveal that various inhalant and dietary allergens have considerable cross-sensitivity, with the elderly having the highest degree of cross-sensitivity and adolescents the lowest.
RESUMO
Objective: Total laryngectomy (TL) patients are good models in which to evaluate the effects of nasal airflow cessation on the sinonasal tract. Here, we evaluated changes in sinonasal structures and association with sinus opacification in the computed tomography (CT) images 3 years post-TL. Methods: Patients who underwent TL from 2005 to 2017 in a teaching academic center were reviewed retrospectively. Patients with a final follow-up CT taken less than 3 years after TL, tracheoesophageal puncture, inadequate CT image, or history of sinonasal surgery were excluded. The control group included patients who underwent a partial laryngectomy or hypopharyngectomy without requiring a tracheotomy for more than a month. Altogether, 45 TL patients and 38 controls were selected. The volume of all four paranasal sinuses, inferior turbinate soft tissue volume (ITSTV), maxillary sinus natural ostium (MSNO) mucosal width, and Lund-Mackay scores (LMS) were measured on preoperative and postoperative CT scans. Results: The mean duration between surgery and the final CT scan was 6.3 ± 2.4 and 5.5 ± 2.3 years for the TL and control groups, respectively. Neither group showed significant changes in the four paranasal sinuses' volume or MSNO mucosa width. The ITSTV decreased significantly, from 4.6 ± 1.3 to 2.8 ± 1.1 mL (p < .001), in the TL group, regardless of the presence of nasal septal deviation, showing ITSTV reduction on both concave and convex sides. By contrast, the control group showed no significant changes in ITSTV. Postoperative LMS changes in both groups were insignificant. The number of patients with LMS aggravation or alleviation was the same in both groups, regardless of preoperative sinus opacification. Conclusions: Paranasal sinus structures and sinus opacification are not affected significantly by nasal airflow cessation; however, the inferior turbinate mucosa is affected by long-term discontinuation of nasal airflow. Level of Evidence: 4 (case-control study).
RESUMO
OBJECTIVES: Inferior meatal antrostomy (IMA) is regarded as a safe method, with minimal complications, for managing various lesions in the maxillary sinus. However, in patients with persisting IMA window, resection of the inferior turbinate may result in direct airflow into the antrum, irritating the antral mucosa. METHODS: Case report and review of literature. RESULTS/CASE: The present report describes a 29-year-old man who previously underwent unilateral IMA for the excision of a dentigerous cyst. The patient did not report any facial pain following the excision of the cyst. One year later, this patient underwent partial resection of the inferior turbinate for the resolution of nasal stuffiness by another surgeon. Soon after surgery, the patient developed severe facial and ocular pain on the side of the IMA, with the pain being especially aggravated upon inhalation. Endoscopy and computed tomography (CT) revealed a persisting IMA window. The patient's severe discomfort was thought to result from direct airflow into the maxillary sinus, as the resected turbinate may have altered normal nasal airflow. A unilateral inferior meatal augmentation procedure (IMAP) with an autologous ear cartilage implant was performed, resulting in complete relief of pain and discomfort. CONCLUSIONS: Although IMA alone is a relatively safe surgical procedure, care should be taken when performing inferior turbinoplasty in patients with persistent IMA opening.

INTRODUCTION: Sinonasal organizing hematoma (OH) is a rare, nonneoplastic lesion that often presents with epistaxis, a reddish mass, and destruction of the involved sinonasal structures. Due to its rarity, the demographics, diagnostic modalities, treatment strategies, and outcomes have not yet been studied in a large, long-term study. MATERIALS AND METHODS: Retrospect cohort of 112 sinonasal OH patients treated between 1997 and 2020 in a tertiary, university hospital were evaluated. Demographics, systemic comorbidities, sinonasal surgery history, serum laboratory tests, radiological findings, and treatment results were collected. The present study aimed to assess the accuracy of preoperative computed tomography (CT), Gadolinum-enhanced magnetic resonance (MR), and punch biopsies in detecting sinonasal OH as the most likely diagnosis. In addition, incidental differences by age and year of diagnosis were calculated using the Poisson log-linear regression model. RESULTS: The median age was 44, and 58% were male. Fewer than 20% of these cases had a chronic systemic comorbidity, bleeding tendency, or sinonasal surgery history. MR had the highest accuracy of (87%) to detect sinonasal OH as the most likely diagnosis, compared with contrast-enhanced-CT (53%), punch biopsy (49%), and non-enhanced-CT (16%) (all <0.05). Sinonasal OH incidence did not vary by age, but the yearly rate significantly increased by 1.05 times over 23 years (p < 0.05). Notably, 84% of 112 patients received surgical removal through the assistance of an endoscope, and none had substantial bleeding without preoperative embolization. CONCLUSION: Sinonasal OH was observed regardless of age, sex, systemic comorbidities, bleeding tendency, prior sinonasal surgery, or trauma. Preoperative MR gives the highest accuracy for detecting this disease. Sinonasal OH may be safely managed with endoscopic-assisted surgery removal without embolization. LEVEL OF EVIDENCE: 4 Laryngoscope, 134:1581-1590, 2024.

In a patient whose sudden vision loss is suspected on the side of a previously operated sphenoid or ethmoid sinus, an ischemic insult to the optic nerve may occur due to a compressing mucocele, especially when there is bony dehiscence of the orbital apex. We report a case of a 41-year-old healthy male patient who had a history of previous sinus surgery, and visited the emergency department for an abrupt left ocular pain following visual loss of the affected eye. The patient's left eye's best corrected visual acuity (BCVA) was hand motions with a reduced light reflex. A sphenoethmoidal sinus cell (Onodi cell) mucocele with bone dehiscence in the left orbital apex was seen on computed tomography. Upon suspicion of compressive ischemic optic neuropathy, urgent endoscopy-assisted endonasal marsupialization of the Onodi cell mucocele with high-dose pulse intravenous dexamethasone was performed. The pathology showed an inflamed nasal mucosa, confirming a mucocele. On the second postoperative day, his BCVA slightly improved in counting fingers at 30 cm. However, even though the nasalized Onodi cell remained intact, his eyesight did not show further improvement. The optic nerve may be directly insulted when a mucocele in the Onodi cell takes place, especially when there is bony dehiscence in the orbital apex. Despite accelerated surgical marsupialization and high-dose steroids, the chance of visual recovery remains very low, as demonstrated in our case.
RESUMO
Raoultella ornithinolytica is an encapsulated, Gram-negative, nonmotile, rod belonging to the Enterobacteriaceae family. Infections involving the gastrointestinal tract and the hepatopancreatobiliary system are most frequently reported, especially in immunocompromised patients. The authors present an unusual case of acute complicated sinusitis with orbital and intracranial involvement caused by R. ornithinolytica. The infection was rapidly progressive, even though the patient was a healthy, young person without any co-morbidities. The patient's condition improved after antibiotic treatment and multiple ophthalmic and sinus surgeries. LEARNING POINTS: Raoultella ornithinolytica can cause rapidly progressive infections, even in immunocompetent young individuals.Raoultella ornithinolytica identified in sinusitis can be a true pathogen rather than an innocent bystander.
RESUMO
Benign tumors or malignant neoplasms must be evaluated in patients with unilateral nasal cavity mass lesions. The 3 most prevalent unilateral benign mass lesions in such individuals are nasal polyps (NPs) and inverted papillomas (IPs). Although rare, it should be kept in mind that sinonasal hamartomas can be occasionally diagnosed as well. Among sinonasal hamartomas, respiratory epithelial adenomatoid hamartoma is more prevalent, with seromucinous hamartoma (SMH) being the second most common. Unlike NPs, sinonasal hamartomas are benign tumors with growth potential, which means it should not be undertreated and warrants surgical removal for treatment. However, sinonasal hamartomas do not have local invasion or malignant transformation potential like IPs; hence, it is vital not to overtreat them. Therefore, understanding the histopathology of SMH and thereby establishing proper surgical planning prior to the surgery remains crucial in such cases. Here, we present a successfully treated case of SMH with a distinctive radiographic, gross, and pathological clinical image of SMH.
RESUMO
Background and Objectives: Limited palatal muscle resection (PMR) is a surgical technique employed to alleviate respiratory disturbances in obstructive sleep apnea (OSA) patients with retropalatal narrowing by reducing soft palate volume and tightening the muscles. Although some previous publications have demonstrated the effectiveness of limited PMR, the overall efficacy and therapeutic role of limited PMR for the treatment of OSA remain uncertain. This study utilized meta-analysis and a systematic literature review to estimate the overall effectiveness of limited PMR in treating OSA. Materials and Methods: Multiple databases, including PubMed, EMBASE, Cochrane Library, and Web of Science, were searched using specific keywords related to OSA and limited PMR. Original articles assessing respiratory disturbances before and after limited PMR in patients with OSA were included. Data from selected articles were collected using standardized forms, including clinicodemographic characteristics, apnea-hypopnea index (AHI), and lowest pulse oximetry values (minimum SpO2). Random effect models were used for analyzing significant heterogeneity. Egger's test and funnel plot were used to identify publication bias. Results: Four studies were included in this meta-analysis for AHI, and three studies were included for minimum SpO2 during sleep. A significant reduction in the AHI and an increase in the minimum SpO2 were shown following limited PMR as the standardized mean difference (95% confidence interval) was 2.591 (1.092-4.090) and 1.217 (0.248-2.186), respectively. No publication bias was found in either analysis. Conclusions: The results of the meta-analysis and systemic review add to the literature that limited PMR can result in a reduction in the AHI and an increase in min SaO2. In OSA patients with suspected retropalatal obstruction, limited PMR may be efficiently performed.

Introduction: Obstructive sleep apnea (OSA) is known to increase the risk of various cancers. By analyzing the Korea National Health Insurance Service (KNHIS) registry, the impact of OSA on the lung cancer incidence was analyzed in a retrospective cohort group. Methods: A retrospective cohort of adult patients newly registered with OSA in the KNHIS data from 2007 to 2017 was included and observed until December 2019 (12 years). The main outcome measure was newly diagnosed lung cancer. The control group was set with age and sex that matched those in the OSA group. Results: The hazard ratio (HR) of OSA for lung cancer incidence showed a significantly reduced HR of 0.87 (95% CI, 0.82-0.93). The observed significance of this finding was limited to male OSA patients [HR, 0.84 (95% CI, 0.78-0.90)], while no significant association was found in female OSA patients [HR, 1.05 (95% CI, 0.91-1.21)], irrespective of their age. Discussion: OSA patients have a lower risk of developing lung cancer, but this risk reduction is gender-specific, as female OSA patients do not show a reduction in hazard ratio.
RESUMO
Obstructive sleep apnea (OSA) has been linked to an increased risk of acquiring many types of cancer. No data on the prevalence of testicular cancer in OSA patients have been reported in the literature. The goal of the present investigation is to find out the impact of OSA on the incidence of testicular cancer based on the Korea National Health Insurance Service (KNHIS) dataset. A cohort of adult male patients newly registered with OSA in the KNHIS data from 2007 to 2014 who had no history of any previous cancer diagnosis was included. The main outcome measure was newly diagnosed testicular cancer in the National Medical Expenses Support Program. The control group was set at five times larger than the OSA group, and it was matched with age and sex. The cumulative incidence and hazard ratio (HR) for the development of testicular cancer were compared between the OSA and control groups. Further subgroup analysis was conducted in the three different age groups. In the study period, a total of 152,801 male adult patients newly diagnosed with OSA were included, whereas 764,005 individuals were recruited as the control group. The HR of OSA for developing testicular cancer was 1.58 (95% confidence interval [CI]: 0.92-2.60), showing no significant HR regardless of confounding adjustment. However, the subgroup analysis revealed a significantly increased HR to develop testicular cancer of 3.39 (95% CI: 1.08-10.06) in groups aged more than 65, whereas the age ranges of 20-40 and 40-64 showed no significance (1.19 (0.44-2.75) and 1.27 (0.50-2.80), respectively). OSA may not influence the incidence of testicular cancer in the general adult population. However, compared to younger males, males over 65 may be more susceptible to OSA when it comes to developing testicular cancer.

It has been claimed that a tighter, reinforced quarantine strategy was advocated to reduce the transmission of coronavirus disease 2019 (COVID-19) during major outbreaks; however, there have been no prior quantitative studies examining the effectiveness and duration of such a reinforced quarantine. Consequently, the purpose of this research was to determine the impact of a "tighter, reinforced" quarantine during the third COVID-19 breakout wave in South Korea, which occurred between late 2020 and early 2021. The efficacy of the quarantine was determined by comparing the number of newly diagnosed COVID-19 patients between the "prediction model" and "actual observed data." Two prediction models were developed using the autoregressive integrated moving average (ARIMA; 1, 0, 0) model. The effect of a "tighter, reinforced" quarantine, which would show as an immediate drop in the number of new cases, predicted its efficacy by lowering the number of new cases by 20,400. In addition, the efficacy of the quarantine lasted up to more than three months. The findings of our investigation confirmed the beneficial influence of "tighter, controlled" quarantine laws during a widespread COVID-19 epidemic. During an epidemic, when the population has not yet developed immunity to respiratory viral diseases, our study may be evidence for implementing stricter quarantine restrictions in order to reduce the number of new cases.
RESUMO
INTRODUCTION: Sinonasal inverted papillomas (IP) can undergo transformation into IP-squamous cell carcinomas (IP-SCC). More aggressive treatment plan should be established when IP-SCC is suspected. Nevertheless, inaccuracy of the preoperative punch biopsy results to detect IP-SCC from IP raises the need for an additional strategy. The present study aimed to investigate significant clinicoradiological remarks associated with IP-SCC than IP. MATERIAL AND METHODS: Postoperative surgical specimens obtained from patients with confirmed IP or IP-SCC at a single tertiary medical center from 1997 to 2018 were retrospectively evaluated. Patients' demographic and clinical characteristics, preoperative in-office punch biopsy results, and preoperative computed tomography (CT) or magnetic resonance images were reviewed. Univariate and multivariate analyses were performed to assess the odds ratio (OR) associated with IP-SCC. The area under the curve (AUC) in the receiver Operating Characteristic (ROC) curve was calculated in the prediction model to discriminate IP-SCC from IP. RESULTS: The study included 44 IP-SCC and 301 patients with IP. The diagnostic sensitivity of in-office punch biopsy to detect IP-SCC was 70.7%. Multivariate analysis showed that factors significantly associated with IP-SCC included tobacco smoking >10PY (adjusted-OR [aOR]: 4.1), epistaxis (aOR: 3.4), facial pain (aOR: 4.2), bony destruction (aOR: 37.6), bony remodeling (aOR: 36.3), and invasion of adjacent structures (aOR: 31.6) (all p < 0.05). Combining all significantly related clinicoradiological features, the ability to discriminate IP-SCC from IP reached an AUC of 0.974. CONCLUSION: IP patients with a history of tobacco smoking, facial pain, epistaxis, and bony destruction, remodeling, or invasion of an adjacent structure on preoperative images may be at higher risk for IP-SCC.

OBJECTIVES: With the increase in dental implants for tooth loss, odontogenic sinusitis following maxillary dental implants is frequently encountered in otorhinolaryngology practice. The authors aimed to reveal the association between implant extrusion into maxillary sinus, along with implant-related complications in patients diagnosed with implant-related odontogenic sinusitis (IR-ODS). STUDY DESIGN: Case-control study. METHODS: This study enrolled 60 patients who received functional endoscopic sinus surgery due to IR-ODS. The preoperative sinus computed tomography was retrospectively reviewed. Among the 120 maxillary sinuses of the 60 patients, 68 sides were diagnosed with IR-ODS sides, whereas 27 sides showed no clinical or radiological evidence of this condition after the implant insertion and were defined as the control sides. Statistical analysis between these two groups was conducted, in addition to odds ratio (OR) calculations for associations with IR-ODS. RESULTS: The mean age of the IR-ODS subjects was 59.5 ± 19.1, with a male to female ratio of 32/28 (53.3%/46.7%). Implants extruding by more than 4 mm into the maxillary sinus, peri-implantitis, bone graft disruption-extrusion were associated with a significantly higher incidence in the IR-ODS (p = 0.035, p = 0.003, p = 0.011, respectively). The IR-ODS sides showed an adjusted-OR (95% confidence interval) of 27.4 (2.7-276.5) for extrusion length >4 mm, 11.8 (3.0-46.5) for peri-implantitis, and 34.1 (3.3-347.8) for bone graft disruption (p = 0.005, p < 0.001, and p = 0.003, respectively). CONCLUSION: Maxillary dental implants extruding more than 4 mm into the maxillary sinus, peri-implantitis, and disrupted-extruded bone grafts show significant association with IR-ODS. LEVEL OF EVIDENCE: 4 Laryngoscope, 133:237-243, 2023.

Deviated nasal septum (DNS) is suggested to be associated with nonspecific inflammation of the nasal mucosa. The authors hypothesized septoplasty may reduce nasal mucosal inflammation, therefore the authors aimed to measure various inflammatory biomarkers in the nasal secretion following septoplasty. Prospectively, 17 patients undergoing elective septoplasty were included. Symptomatic changes after septoplasty were evaluated with Sino-nasal Outcome Test (SNOT-22) and Nasal obstruction symptom evaluation (NOSE) scores. Using acoustic rhinometry, changes of the nasal airway volume were measured. Nasal secretion was collected within 2 weeks and 3 months before and after septoplasty, respectively. The inflammatory biomarker high-mobility group box 1 (HMGB1) and vasoactive intestinal peptide (VIP), and inflammatory cytokines including tumor necrosis factor α (TNF α), interferon γ (IFN-γ), interleukin-4 (IL-4), eotaxin-1, and regulated upon activation, normal T cell expressed and presumably secreted (RANTES) were quantified in the nasal secretion by enzyme-linked immunosorbent assays or multiplex bead array assays. The patients' mean age was 30.5 ± 6.8 (ranging from 19 to 43), consisting of 15 male and 2 female patients. The median SNOT-22 and NOSE scores changed from 54 to 14 and 78 to 15, respectively, both showing a significant decrease. In acoustic rhinometry, nasal cavity volume of convex side significantly increased after septoplasty, whereas significant discrepancy of nasal airway volume between concave and convex sides became insignificant. No significant difference was noted both before and after septoplasty between the concave and convex sides in all seven biomarkers. The HMGB1, RANTES, IL-4, and TNF-α concentrations following septoplasty showed significant decrease in 34 nasal cavities of 17 patients (all p < 0.05). However, when the 17 concave and 17 convex sides were analyzed separately, the significant reduction in four biomarkers were only significant in the concave sides (all p < 0.05), but not significantly reduced in convex sides. Septoplasty may have benefited not only in normalizing the nasal airflow and symptom improvement, but also in nonspecific inflammation attenuation in the nasal airway.

BACKGROUND AND OBJECTIVES: To investigate the diagnostic validity of auditory brainstem response (ABR) in the screening of vestibular schwannoma (VS). SUBJECTS AND METHODS: Forty patients diagnosed with VS using magnetic resonance imaging who had undergone ABR before treatment between 2005 and 2015 were included. ABR results were considered positive when findings met at least one of the following criteria: 1) absent evoked response, 2) desynchronization of waves other than wave I, 3) interpeak latency (IPL) between waves I and III >2.5 ms, 4) IPL between waves I and V >4.4 ms, 5) wave V interaural latency difference >0.2 ms, and 6) interaural difference in IPL between waves I and V >0.2 ms. RESULTS: The overall sensitivity of ABR was 85.0%. For tumors measuring <10 mm, the sensitivity of ABR was 66.7%, whereas it increased to 90.3% for tumors measuring >10 mm. The sensitivity of tumors confined to the internal acoustic canal was 73.3% compared with 100.0% for tumors confined to the cerebellopontine angle. In patients with serviceable hearing, the mean tumor size was 7.8±2.9 mm in patients with a normal ABR and 15.1±9.4 mm in patients with an abnormal ABR, indicating a significant difference (p<0.05). CONCLUSIONS: ABR alone is insufficient for the screening of VS, bearing the risk of false-negative outcomes when examining small, intracanalicular tumors. However, ABR can be inexpensively applied for the screening of VS measuring >10 mm in patients with serviceable hearing, supporting the need for further active diagnostic and treatment modalities in clinical practice.
RESUMO
OBJECTIVES: The current study aims to determine the correlation between nutritional status upon presentation and disease severity, as well as treatment and survival outcomes. METHODS: Patients who were diagnosed with deep neck infection, underwent at least one surgical drainage/debridement, and had more than 1 week of hospitalization at a tertiary medical center from 2007 to 2015 were retrospectively included. Thereafter, initial serum albumin, C-reactive protein (CRP), and body mass index (BMI) were reviewed. RESULTS: A total of 135 patients were included in the final analysis. Accordingly, the proportion of patients with simultaneous mediastinitis (21.0%), necrotizing fasciitis (12.9%), disease extent >1 cervical level (72.6%), mean CRP (22.4 mg/dL), mean length of hospitalization (25.0 days), and mean 1-week follow-up CRP (7.2 mg/dL) was significantly higher in the hypoalbuminemia group (initial serum albumin <3.0 g/dL) than in the normoalbuminemia group (all P<0.05). No significant correlations had been observed according to BMI status. After adjusting for age and Charlson comorbidity index, odds ratios for the following outcomes were calculated in patients initially presenting with hypoalbuminemia: simultaneous mediastinitis (3.07), necrotizing fasciitis (7.89), disease extent >1 cervical level (2.12), initial serum CRP over 20 mg/dL (3.79), hospitalization of more than 14 days (4.10), 1-week follow-up CRP over 5 mg/dL (3.78), and increased duration for an over 50% decrease in initial CRP (2.70) (all P<0.05). Although intravascular albumin replenishment decreased the proportion of patients with hypoalbuminemia after 2 weeks (P<0.05), it did not significantly predict better treatment outcomes. CONCLUSION: Among the markers reflecting an individual's nutritional state, an initial serum albumin of less than 3.0 g/dL was an independent serologic marker predicting increased disease severity and complications in patients with deep neck infection.
RESUMO
BACKGROUND: Circulating biomarker (CB) is a convenient, emerging predictive tool for treatment response and outcomes in human cancers. Therefore, we examined the prognostic value of pre-treatment and early post-treatment CBs and their summated scores in patients with head and neck squamous cell carcinoma (HNSCC). METHODS: This study prospectively included 310 consecutive patients who underwent definitive treatment for previously untreated advanced-stage HNSCC between 2010 and 2015. The CB score was determined by complete blood counts (CBCs) and blood chemistry before and 2 months after the treatment, and the number of abnormal CB was counted from 0 to 10. Univariate and multivariate analyses with Cox proportional hazards models were used to find factors associated with disease-free survival (DFS) and overall survival (OS). RESULTS: Most CBC profiles were significantly changed at 2-months post-treatment compared with those at pre-treatment. Univariate analyses showed that hypoalbuminemia, leucocytosis, C-reactive protein, high CB scores (≥6), age, performance status and comorbidity and tumour site were significantly associated with DFS and OS (all P < 0.05). Both pre- and post-treatment CB scores were independent factors predictive of DFS and OS outcomes in the multivariate analyses (P < 0.05). High CB scores at pre-treatment were associated with 7-10-fold increased risk of unfavourable DFS and OS outcomes, and those at 2-months post-treatment were associated with 2 to 4-fold increased risk of poor survival outcomes (all P < 0.05). CONCLUSIONS: CB scores at pre-treatment and early post-treatment are useful for predicting survival outcomes in patients with advanced-stage HNSCC.

OBJECTIVE: De novo cancers of head and neck area in solid organ transplantation recipients show standardized incidence ratio (SIR) of 3.8. Immunosuppression following transplantation is suggested to play as a crucial factor in pathogenesis of secondary malignancy. Prognosis of head and neck cancer arising in solid organ transplantation recipients is proven to have poor prognosis. The incidence, risk, prognosis, and survival of de novo malignancy of head and neck area in solid organ transplantation recipients in single-tertiary medical center followed up for 20 years. METHODS: A retrospective medical record review of the patients who received solid organ transplantation in Asan Medical Center from 1997 to 2016 was conducted. Patients confirmed as de novo malignancy in the head and neck area after organ transplantation were included, and presented as in the case-series format. Patients with previous history of head and neck malignancy, irradiation history of head and neck area, cutaneous malignant lesion, hematopoietic malignant lesion, malignancy of thyroid and parathyroid gland and metastatic lesions newly developed in head and neck area were excluded. The incidence of head and neck malignancy in South Korea were reviewed from the National Cancer Information Center of South Korea. For the statistical analysis, standardized incidence ratio (SIR) was obtained with 95% confidence interval. RESULTS: Solid organ transplantation recipients show 20 times higher incidence of de novo cancer of head and neck area compared to general population. Of 13 de novo head and neck malignancy arising after solid organ transplantation, 2 (15.4%) patients were unable to withstand definitive management due to poor general condition. 2 (15.4%) patients had loco-regional recurrence, 1 (7.7%) patient with distant metastasis, and 3 (23.1%) patients died of cancer progression. CONCLUSION: Immunosuppression following solid organ transplantation gives a twenty-fold increased risk for the development of de novo head and neck cancer. A more precise and frequent checkup on head and area should be planned, suggesting a multi-disciplinary approach in combination with organ transplantation team.

OBJECTIVES: To investigate the changes in hearing and to determine factors predicting hearing deterioration in patients with vestibular schwannoma (VS) who undergo gamma knife radiosurgery (GKRS). DESIGN: A retrospective review of medical records in patients diagnosed with VS and initially treated with GKRS at a tertiary care medical center between 1995 and 2015 was performed. Tumor factors (location, volume), parameters related to irradiation to the tumor and cochlea, and distance between the tumor and cochlea were reviewed. RESULTS: Fifty-six patients were included in the final analysis with a mean observation period following GKRS as 24.4 ± 27.8 months. Prior to GKRS, the average pure tone threshold at 500, 1k, 2k, and 4k Hz (PTA4) was 51.0 ± 29.7 dB HL. After GKRS, the mean PTA4 was 71.6 ± 33.3 dB HL. Significant independent odds ratios for hearing deterioration were 8.5 for extracanalicular tumors, 18.8 for more than 10 shots in GKRS, and 12.2 for a distance between the tumor center and cochlea modiolus less than 20 mm. CONCLUSIONS: A significant hearing deterioration was shown in 2 years after GKRS. Tumor location, number of radiation shots, and distance between the tumor and cochlea affected hearing level after GKRS.
