Clinical and surgical factors affecting the prognosis and survival rates in patients with mucormycosis.

PURPOSE: To investigate the factors affecting disease specific mortality (DSM) in patients with mucormycosis. METHODS: This retrospective study included 24 patients diagnosed with mucormycosis and who had undergone surgical and medical treatment between 2010 and 2020. There were 14 male and 10 female patients whose mean age was 53.70 ± 16.87 years, range 18-83. We reviewed the factors affecting DSM, including the extent of disease (paranasal sinus, palatal, orbital or intracranial involvement) and blood parameters (BP) that are serum glucose level (SGL), white blood cell, neutrophil, lymphocyte counts, C-reactive protein and hemoglobulin levels. Also, the effect of SGL in diabetes mellitus and BP in hematological malignancies on DSM was additionally evaluated. RESULTS: Orbital (p = 0.001) and intracranial (p < 0.01) involvement had statistically significant effect on DSM but not the palatal involvement. When Cox regression analysis was employed to analyze the effect of multiple independent factors on DSM, only the extent of disease (p = 0.023) had statistically significant effect. Receiver operating characteristic analysis of SGL for diabetic patients demonstrated that the area under the curve was 0.917 (p = 0.016). A cut-off SGL of 360 mg/dl revealed an 83.3% sensitivity and 83.3% specificity for mortality outcome for diabetic patients having mucormycosis. CONCLUSION: Orbital or cerebral involvement is related to a poor prognosis, so early endoscopic nasal examination, diagnosis and treatment are of vital importance for DSM in mucormycosis. Serum glucose level over 360 mg/dl in uncontrolled diabetic patients with fever, ophthalmological findings and facial hypoesthesia should necessitate a consultation to an otolaryngologist and an endoscopic careful nasal examination.

Endoscope Assisted Subcochlear Approach for Symptomatic Petrous Apex Effusion.

ABSTRACT: Petrous apex effusions are rare disorders and usually occur in the petrous apex (PA) having well-aerated cells and it may present with several symptoms or can be diagnosed incidentally on imaging methods obtained for another reason. If there are persistent symptoms despite the conservative treatment in symptomatic patients, a surgical attempt can be considered. In patients with favorable hearing levels and with the well-pneumatized petrous bone, PA cells may be effectively drained through subcochlear or supracochlear approaches by preserving patient's hearing levels. In this case report, the authors presented a severe symptomatic patient with petrous apex effusion who did not respond to conservative treatment and petrous apex drainage was performed via the subcochlear approach.

The effect of partial and total laryngectomy on couples' sexual functions in men with larynx cancer.

PURPOSE: To investigate effect of total or partial laryngectomies with or without adjuvant treatments on couples' sexual functions. METHODS: The study included 39 male patients with laryngeal cancer and their female partners who were sexually active. Twenty-six patients underwent total laryngectomy, and 13 had partial laryngectomy. Sexual functions were assessed with the International Index of Erectile Function (IIEF-5) questionnaire for erectile functions, the Male Sexual Health Questionnaire (MSHQ-4) for ejaculatory functions and the Female Sexual Function Index (FSFI) for female partners' sexual functions. RESULTS: The mean IIEF score significantly decreased from 21.51 ± 8.78 to 16.13 ± 9.6 after the surgery (p = 0.000). The mean MSHQ score significantly decreased from 12.95 ± 3.14 to 10.32 ± 4.59 after the surgery (p = 0.000). To investigate risk factors that might predict decreasing in post-operative erectile and ejaculatory function of the male patients, presence of pre-operative erectile dysfunction (p = 0.04) and additional treatment with chemo-radiation therapy were the predictors for decreases in erectile (p = 0.006) and ejaculatory functions (p = 0.036). The mean FSFI total score significantly decreased from 25.83 ± 7.42 to 13.45 ± 10.09 after the surgery (p = 0.000). CONCLUSION: Laryngectomies have negative impact on male erectile and ejaculatory functions, and also have negative effect on female partners' sexual functions. Presence of pre-operative erectile dysfunction and additional chemo-radiation therapy were the predictors to decrease in erectile and ejaculatory functions after surgery. Therefore, male patients and their female partners should be informed in light of these findings before laryngeal surgery and adjuvant therapy.

Radiologic Evaluation of Exiting Points of Supraorbital Region Neurovascular Bundles in Patients With Migraine.

PURPOSE: To reveal the presence and nature of exiting points of supraorbital region neurovascular structures and determine the distances of those structures to midline with computed tomography images by taking into account gender and sides in patients with migraine. METHODS: The study was conducted retrospectively on computed tomography images of 70 migraine and 70 control patients with a mean age of 39.5 ±â€Š13.8 years (range: 18-80). Presence and nature (foramen or notch) of exiting points of neurovascular structures in terms of side and gender in both groups, and the distances of these structures to the midline of the face were evaluated. RESULTS: In migraine and control groups, the most commonly seen structure was single notch. Coexistence of foramen and notch was statistically significant in migraine and female migraine groups than control and female control groups (P < 0.05). Bilateral presence of supraorbital structure was 51.4% in migraine group and 64.3% in control group patients. In all cases, foramen-midline distance was statistically significant longer than the notch-midline distance (P < 0.05). In migraine patients, no statistically significant difference was detected regarding distances of foramen and notch to midline in terms of side and gender. CONCLUSION: Consideration of variable presence and location of the supraorbital notch and foramen, analysis of computed tomography scan might be beneficial in preoperative planning of foraminotomy and fascial band release in adult migraine patients to prevent intraoperative complications. Also, coexistence is more frequent on left side in migraine patients that might cause overlooking those structures during surgery.

Surgical Treatment of Rhinosinusitis-Related Orbital Complications: Factors Affecting Irreversible Blindness.

If left untreated, rhinosinusitis can rarely cause a devastating complication irreversible blindness (IB). Despite new technologies in endoscopic sinus surgery and use of new broad-spectrum antibiotics, IB outcome is still a problem for surgically treated orbital complication of paranasal sinus infection (OCPSI) patients, and factors leading to IB outcome are not actually known. The aim of this study was to assess the factors leading to the IB outcome for surgically treated OCPSI patients. Results of 25 surgically treated OCPSI patients in our clinic were combined with surgically treated OCPSI patients reported through the PubMed database search from the year 2007. Patients were divided into 2 groups: IB group and recovery group. Patients having at least 1 immune status-related additional risk factor (ARF) were more common in the IB group, having an at least 1 ARF had 1.683 risk value of IB outcome (RR: 1.683, P = 0.006). IB patients had statistically significant higher mean (21.87 ±â€Š40.35, P = 0.005) time interval (days) (TI) between onset of ophthalmological symptoms and surgical intervention compared to recovery group patients (2.92 ±â€Š2.53). ROC curve analysis for an estimation of IB outcome according to the TI value demonstrated that a cut-off value of ≥2.5 days had the ideal sensitivity (87.5%) and specificity (71.9%) that resulted in IB outcome. (80.5% power, P = 0.008) IB and recovery group patients did not differ according to orbital complication type according to Chandler's classification (P = 0.492) and white blood cell count status (P = 0.584). In conclusion, OCPSI patients with ARFs and delayed admission after onset of orbital symptoms have a higher risk of IB outcome. These patients deserve prompt evaluation and early surgical intervention to prevent blindness. With future studies, new surgical criteria, including the ARF status and onset of ophthalmological symptoms (≥2.5 days) may be added to classical surgical criteria to prevent IB for OCPSI cases.

Infective endocarditis and risk of death after cardiac implantable electronic device implantation: a nationwide cohort study.

AIMS: To determine the incidence, risk factors, and mortality of infective endocarditis (IE) following implantation of a first-time, permanent, cardiac implantable electronic device (CIED). METHODS AND RESULTS: From Danish nationwide administrative registers (beginning in 1996), we identified all de-novo permanent pacemakers (PMs) and implantable cardioverter defibrillators (ICDs) together with the occurrence of post-implantation IE-events in the period from 2000-2012. Included were 43 048 first-time PM/ICD recipients. Total follow-up time was 168 343 person-years (PYs). The incidence rate (per 1000 PYs) of IE in PM was 2.1 (95% confidence interval [CI]: 1.7-2.6) for single chamber devices and 6.2 (95% CI: 4.5-8.7) for cardiac resynchronization therapy (CRT); similarly, the rate of IE in ICD was 3.7 (95% CI: 2.9-4.7) in single chamber devices and 6.3 (95% CI: 4.4-9.0) in CRT. In multivariable analysis, increased PM complexity served as independent risk factor for IE {dual chamber PM [hazard ratio (HR) 1.39; 95% CI: 1.07-1.80] and CRT [HR: 1.84; 95% CI: 1.20-2.84]}. During follow-up, generator replacement (HR: 2.79; 95% CI: 1.87-4.17) and lead revision (HR: 4.33; 95% CI: 3.25-5.78) in PMs were associated with increased risk. Corresponding estimates in ICDs were 2.49 (95% CI: 1.28-4.86) and 6.58 (95% CI: 4.49-9.63). Risk of death after IE was significantly increased in PM and ICD with HRs of 1.56 (95% CI: 1.33-1.82) and 2.63 (95% CI: 2.00-3.48), respectively. CONCLUSION: The risk of IE increased with increasing PM complexity. Other important risk factors were subsequent generator replacement and lead revision. IE was associated with an increased risk of mortality in the area of CIED.

Transseptal suturing technique in septoplasty: impact on bacteremia and nosocomial colonization.

Although effects of Merocel® nasal packs and silicone splints on nasal flora alterations and bacteremia formation after septoplasty were assessed before, the effect of transseptal suturing technique has not been studied yet. The objective of this study is to compare nasal flora alterations and bacteremia occurrence rates between Merocel packs, silicone splints, and transseptal suturing technique in septoplasty. Ninety patients were divided into three groups randomly: Merocel packing (Group M), silicone splint (Group S), and transseptal suturing without packing (Group T). Group M and S received prophylactic antibiotics and antibiotic pomade application to packs, whereas neither antibiotic prophylaxis nor topical pomade was applied to Group T. Preoperative, after pack removal and 1 month after pack removal nasal swab cultures and preoperative, immediately after surgery and 24 h after surgery blood cultures were taken from all patients. Group M increased Methicillin-sensitive Staphylococcus aureus (MSSA) colonization (p = 0.003) and decreased normal flora colonization (p = 0.038), whereas Group S and T did not affect MSSA or normal flora colonization (p > 0.05). Antibiotic prophylaxis did not affect MSSA colonization (p = 0.14), whereas decreased normal flora colonization (p = 0.029). Transseptal suturing did not prevent bacteremia formation. Postoperative increasing of MSSA colonization in nasal cavity for septoplasty patients can be prevented by using transseptal suturing technique or silicone splints instead of Merocel packing, rather than applying prophylactic antibiotic treatment. Using transseptal suturing does not prevent bacteremia formation during septal surgery. These findings should be kept in mind to prevent postoperative life-threatening infective complications of septoplasty especially in immunosuppressive patients and patients with cardiovascular diseases.

Stapler Esophageal Closure During Total Laryngectomy.

Mechanical esophageal closure with stapler during total laryngectomy has been used by various authors to decrease the surgical time and pharyngocutaneous fistula (PCF) rates. In a few of the studies, surgical site infection (SSI) rates are mentioned and none of the studies emphasize the effect of decreased surgical time on postoperative cardiovascular and cerebrovascular complications. In this study, the authors compared the PCF rates, SSI rates, operation times between 30 mechanical stapler and 40 manual esophageal closure during total laryngectomy for laryngeal cancer patients. National Nasocomial Infections Surveillance system (NNISS) scores were recorded and compared between groups. Total laryngectomy and total operation times were lower in the stapler group patients (P < 0.001 for total laryngectomy time, P = 0.024 for total operation time). There were lower rates of pharyngocutaneous fistula (P = 0.032), surgical site infection (P = 0.019), and NNISS scores (P = 0.009) in the stapler group. There was no statistically significant difference between groups regarding postoperative systemic complications (P = 0.451). In conclusion, stapler esophageal closure decreases operation time, PCF, SSI rates, and NNISS scores but not the systemic complication rates. Comorbid illnesses and prolonged surgical time are risk factors for postoperative systemic complications in total laryngectomy patients, but patients with additional illnesses must not encourage the surgeon to use stapler for decreasing postoperative systemic complications.

Botulinum Toxin for Rhinitis.

PURPOSE OF REVIEW: Rhinitis is a common clinical entity. Besides nasal obstruction, itching, and sneezing, one of the most important symptoms of rhinitis is nasal hypersecretion produced by nasal glands and exudate from the nasal vascular bed. Allergic rhinitis is an IgE-mediated inflammatory reaction of nasal mucosa after exposure to environmental allergens. Idiopathic rhinitis describes rhinitis symptoms that occur after non-allergic, noninfectious irritants. Specific allergen avoidance, topical nasal decongestants, nasal corticosteroids, immunotherapy, and sinonasal surgery are the main treatment options. Because the current treatment modalities are not enough for reducing rhinorrhea in some patients, novel treatment options are required to solve this problem. RECENT FINDINGS: Botulinum toxin is an exotoxin generated by Clostridium botulinum. It disturbs the signal transmission at the neuromuscular and neuroglandular junction by inhibiting the acetylcholine release from the presynaptic nerve terminal. It has been widely used in neuromuscular, hypersecretory, and autonomic nerve system disorders. There have been a lot of published articles concerning the effect of this toxin on rhinitis symptoms. Based on the results of these reports, intranasal botulinum toxin A administration appears to be a safe and effective treatment method for decreasing rhinitis symptoms in rhinitis patients with a long-lasting effect. Botulinum toxin type A will be a good treatment option for the chronic rhinitis patients who are resistant to other treatment methods.

Oral anticoagulation therapy after radiofrequency ablation of atrial fibrillation and the risk of thromboembolism and serious bleeding: long-term follow-up in nationwide cohort of Denmark.

AIM: To investigate the long-term risk of thromboembolism and serious bleeding associated with oral anticoagulation (OAC) therapy beyond 3 months after radiofrequency ablation (RFA) of atrial fibrillation (AF). METHODS AND RESULTS: Linking Danish administrative registries, 4050 patients undergoing first-time RFA (2000-11) were identified. Risk of thromboembolism and serious bleeding according to OAC therapy were analysed by incidence rates (presented per 100 person-years) and Cox proportional-hazard models. The median age was 59.5 years (interquartile range, IQR: 52.8-65.2); 26.5% were females. During a median follow-up of 3.4 years (IQR: 2.0-5.6), 71 (1.8%) thromboembolism cases were identified, where incidence rates with and without OAC were 0.56 (0.40-0.78)95%CI and 0.64 (0.46-0.89)95%CI, respectively. Oral anticoagulation discontinuation remained insignificant [hazard ratio 1.42(0.86-2.35)95%CI] in multivariable analysis. Beyond 3 months after RFA 87 (2.1%) serious bleedings occurred; incidence rates with and without OAC were 0.99 (0.77-1.27)95%CI and 0.44 (0.29-0.65)95%CI, respectively. Oral anticoagulation therapy was significantly associated with serious bleeding risk [hazard ratio 2.05(1.25-3.35)95%CI]. In an age- and gender-matched cohort (1 : 4) of 15 848 non-ablated AF patients receiving rhythm-control therapy, thromboembolic rates with and without OAC were 1.34 (1.21-1.49)95%CI and 2.14 (1.98-2.30)95%CI, respectively. Adjusted incidence rate ratio was 0.53 (0.43-0.65)95%CI favouring RFA cohort. CONCLUSION: Thromboembolic risk beyond 3 months after RFA was relatively low compared with a matched non-ablated AF cohort. With cautious interpretation due to low number of events, serious bleeding risk associated with OAC seems to outweigh the benefits of thromboembolic risk reduction. Randomized studies are warranted to test our results.

The influence of direct rigid laryngoscopy on the nosocomial colonization and bacteremia.

OBJECTIVE: Direct rigid laryngoscopy (DRL) is a relatively simple and well-tolerated procedure that can provide both diagnostic and therapeutic benefits. There are no data regarding the risk of acquiring bacteremia after DRL. The purpose of this prospective study was to assess the frequency of bacteremia and nosocomial colonization following DRL and to identify possible risk factors for the development of these complications. METHODS: In this study, 55 consecutive patients with benign or malignant laryngeal pathologies undergoing DRL were included between January 2010 and January 2011. The patients have benign laryngeal lesions and suspicious malignancy. In appropriate circumstances of each patient before intubation and at postoperative 24 hours of throat swab, samples were taken in the transport medium of the patients who underwent planned DRL and underwent surgery. The samples were evaluated in our Microbiology Department. Blood cultures were performed using automated system at postoperative 5 and 24 hours. For each patient at preoperative and postoperative period, C-reactive protein levels in blood samples were measured. SPPS 16 package program was used for statistical analysis. RESULTS: The distribution of sex was 45 males and 10 females with average age of 51.4 (between 23 and 99 years). Patients who had malignant lesions (n = 17) accounted for 30.9% of all patients. Preoperative Candida colonization was recovered from the cultures obtained from 9 oropharyngeal specimens (16.4%). Postoperative oropharyngeal nosocomial bacteria colonization was observed in 14 patients (25.5%). Nosocomial colonization was found related to malignancy (P = 0.014). C-reactive protein levels of patients before and after surgery were not statistically significant (P > 0.05). At postoperative 5 and 24 hours, blood cultures of all patients were negative. Postsurgical bacteremia was not observed. CONCLUSIONS: Although there is no association between DRL and bacteremia, nosocomial colonization may be significant. Nosocomial colonization possesses a risk of development of infection especially in patients with malignancy.

Two rare entities in the same palate lesion: hyalinizing-type clear cell carcinoma and necrotizing sialometaplasia.

Hyalinizing clear cell carcinoma is a low-grade malignant epithelial neoplasm of the salivary glands. The tumor has epithelial cells and lacks myoepithelial cells. Necrotizing sialometaplasia is a benign, self-limiting lesion of the salivary glands. The clinical and histologic features mimic those of mucoepidermoid carcinoma or squamous cell carcinoma. The importance of these entities are the rarity of both of them and their potential to be misdiagnosed as other lesions. Pathologists and clinicians should be aware of these entities to prevent misdiagnosis. This is the first clinical report of 2 rare and consecutive different entities of the same location on the hard palate to our knowledge.

Sinolith: a rare isolated sphenoid sinus lesion.

Sinolith is a calculus in the paranasal sinuses. It has been also known as antrolith, rhinolith, antral calculi, antral stone, or antral rhinolith. The pathogenesis of calculi formation within a paranasal sinus is still not known. Chronic infection, foreign material, poorly draining sinus, and fungal infection are the main predisposing factors. Isolated sphenoid sinus lesions are rare, and most of them are inflammatory diseases. The main symptom of sphenoid sinus lesions is headache. Headache may be the only symptom of sphenoid sinus lesions. Sinolith is mostly encountered in the maxillary sinus followed by the frontal sinus and the ethmoid sinus. There was only 1 publication about sinolith localized in the sphenoid sinus in the English language literature. We report a case of an isolated sinolith localized in the sphenoid sinus. The treatment of choice should be surgical removal of the sinolith. Endoscopic surgery especially through the transnasal route should be the first-choice surgical treatment of isolated sphenoid sinus lesions.

Thyroid isthmus agenesis associated with thyroid papillary carcinoma. [corrected].

A wide range of morphological varieties and developmental anomalies of the thyroid gland have been reported in literature such as hypoplasia, ectopy, hemiagenesis, and agenesis. Out of these, the incidence of agenesis of the thyroid isthmus is rare, and very few cases have been reported. In the present case report, a female patient was found with agenesis of thyroid isthmus with thyroid papillary carcinoma in the right lobe. In this article, we report a case of thyroid isthmus agenesis and reviewed the associated literature.

Rhino-orbito-cerebral mucormycosis in patients with diabetic ketoacidosis.

Mucormycosis is a life-threatening fungal infection that occurs in immunocompromised patients. The most common predisposing risk factor for mucormycosis is diabetes mellitus. Rhino-orbito-cerebral mucormycosis is the most common form in diabetic patients and is characterized by paranasal sinusitis, ophthalmoplegia with blindness, and unilateral proptosis with cellulitis, facial pain with swelling, headache, fever, rhinitis, granular or purulent nasal discharge, nasal ulceration, epistaxis, hemiplegia or stroke, and decreased mental function. Diabetic ketoacidosis is the most common and serious acute complication of diabetic patients. We herein report 2 cases of fatal rhino-orbito-cerebral mucormycosis in a patient with diabetic ketoacidosis.

[The effects of thermal welding tonsillectomy on postoperative pain]. / Termal welding tonsillektominin ameliyat sonrasi agri üzerinde etkisi.

OBJECTIVES: This study aims to compare the effects of the thermal welding tonsillectomy and conventional cold dissection tonsillectomy on the postoperative pain. PATIENTS AND METHODS: Between November 2009 and May 2011, 60 pediatric patients (38 boys, 22 girls; mean age 8.4 years; range 5 to 15 years) who underwent tonsillectomy due to chronic tonsillitis or obstructive sleep apnea were included. Tonsillectomy with thermal welding was performed on 30 patients and conventional cold dissection tonsillectomy was performed on the 30 patients. Postoperative pain was assessed by visual analog scale. Postoperative first day pain score was accepted as 10 and the patients were asked to score between 0-10 for other nine days. Student t-test was used for the statistical evaluation of pain scores in the first five days, while Mann-Whitney-U test was used for the other days. RESULTS: In the first five day evaluation, the mean pain score was 35.83 for cold dissection tonsillectomy and 31.90 for thermal welding tonsillectomy. The mean pain value for the last five days was 15.6 for cold dissection tonsillectomy and 10.33 for thermal welding tonsillectomy. The mean pain scores of cold dissection tonsillectomy were statistically significantly higher, compared to thermal welding tonsillectomy for first five day, last five day and total 10 days (p<0.05). CONCLUSION: We consider that thermal welding tonsillectomy results in lower postoperative pain, compared to the conventional cold dissection tonsillectomy.

Results of 301 Parotidectomies: A Twenty-Year Experience of One Single Institution.

To evaluate demographic, clinical, surgical and histopathological results and complications of 301 parotidectomies performed in southern part of Turkey. The results of 297 patients undergoing 301 parotidectomies between 2000 and 2019 were retrospectively reviewed. Four patients underwent bilateral parotidectomy. Age, gender, side and size of lesion, postoperative facial nerve function (FNF) for benign tumors and types of surgery were evaluated. There were 172 male and 125 female patients. The mean age was 52.53 ± 16.67 years (range 11-90 years). Patients with malignant tumor had higher mean age than the patients with benign diseases (p < 0.001) and the mean age of Warthin tumor (WT) patients was significantly higher than pleomorphic adenoma (PA) (p < 0.001). There was a significant male dominancy in WTs than the PAs (p < 0.001). The mean size of the malignant tumors was significantly higher than the benign tumors (p = 0.012). The mean of cigarette smoking value (pack/year) was higher in WTs than the PAs (p < 0.001). WT incidence was slightly higher than PA in between years 2010 and 2019 (p = 0.272) compared to between years 2000 and 2009. Fine needle aspiration biopsy had a sensitivity of 96% and specificity of 78% for the benign tumors. Tumor location (p < 0.001) and tumor size (p = 0.034) had negative effect on the postoperative FNF. The incidence of WT had a significant rise in the last decade. Deep lobe tumors and increased tumor size had effect postoperative FNF. Experience of surgeon is more important than nerve monitoring to prevent facial paralysis. Partial superficial parotidectomy was available methods for small benign tumors in tail of the parotid gland.

Do Lymph Node Ratio and Histopathologic Parameters Have Any Prognostic Value in Primary Parotid Gland Carcinomas?

Objective: To analyze the demographic characteristics and the pathological results of neck dissection in primary parotid gland (PG) cancer patients, and to investigate the effects of histopathological parameters (perineural invasion, lymphovascular invasion, and extracapsular spread), neck metastasis, stage and lymph node ratio (LNR) on survival. Methods: Patients who underwent parotidectomy for malignant PG tumors between 2000 and 2019 years were retrospectively reviewed from the medical records. Thirty patients who were treated with parotidectomy and neck dissection were included in the study. Lymph node ratio was calculated as the ratio of the number of metastatic lymph nodes (LN) to the total number of excised LNs. Tumor stage, regional LN metastasis, LNR, perineural invasion, lymphovascular invasion, and extracapsular spread were reviewed for the effects on survival with the Kaplan-Meier analysis. Results: The study included 17 (57%) male and 13 (43%) female patients. Their mean age was 67.93±16.90 years (range, 50-85 years). The average number of the excised LN was 26.03±11.79 (range, 3-50). Mean LNR was 0.16±0.26. The Kaplan-Meier analysis showed that neck metastasis (p=0.001) and LNR (p<0.001) were associated with shorter survival times compared to perineural invasion (p=0.818), lymphovascular invasion (p=0.154), extracapsular spread (p=0.410) and stage (p=0.294). In multivariate COX regression analysis, only LNR had a statistically significant difference (p=0.027) compared to the other parameters. Conclusion: The present study suggests that LNR and neck metastasis are associated with shorter survival times in PG cancers. Lymph node ratio can be used as a prognostic marker in these patients.

Mortal condition in an unusual localization, analysis of isolated tongue and tongue base abscesses.

BACKGROUND: Tongue abscess (TA) is a very rare clinical condition and its treatment is very important. Surgical drainage is at the forefront in the treatment. Our study includes patients with tongue and tongue base abscesses. AIM: To discuss the clinical and laboratory findings of these patients emphasizing the underlying causes and treatment options with the largest patient series in the English literature. METHODS: We included patients with isolated TA who applied to our clinic between January 1, 2020 and January 1, 2023. Those who lack the recorded data, those who are not between the ages of 18-66, those who have not undergone surgery-interventional procedure, and those who have infection and/or abscess in another place were excluded from the study. RESULTS: There were two female (18%) and nine male (82%) patients in our series consisting of 11 patients. Their ages ranged from 18 to 66, and the mean ± SD was 48.63 ± 16.3. Considering the localization of the abscess, three anterior abscesses (27%), two lateral abscesses (18%), and six abscesses at the base of the tongue (54%) were detected. CONCLUSION: Tongue abscesses can cause acute upper airway obstruction and respiratory collapse. It may be necessary to act quickly for the tracheotomy procedure and this procedure can usually be performed under local anesthesia as intubation cannot be achieved. When we encounter an abscess in an unexpected organ, difficulties may be encountered in the management of the patient.
