Efficacy of radiological depth of invasion measurements on magnetic resonance images acquired at different magnetic field strengths and imaging sequences in predicting cervical lymph node metastasis and other outcomes in tongue cancer.

OBJECTIVES: We investigated the correlation between magnetic resonance imaging (MRI) parameters and tumor pathological depth of invasion (pDOI), between pDOI and radiological DOI (rDOI), between rDOI and duration between biopsy and MRI, and between rDOI and duration between MRI and surgery to determine the efficacy of rDOI in identifying small lesions and other conditions. STUDY DESIGN: We examined 36 adult patients who had been diagnosed histopathologically with cancer of the tongue and had undergone a glossectomy. Using 1.5 Tesla (T) and 3.0T MRI, we measured rDOI at the deepest infiltration point on 4 MRI sequences. We calculated the correlations between rDOI and the variables examined by Spearman rho analysis and evaluated the diagnostic performance of rDOI by receiver operating characteristic curve analysis. RESULTS: Axial T2-weighted images using 1.5T MRI provided the closest approximation of pDOI. Although the correlation between rDOI and pDOI was significant, rDOI showed poor or acceptable discrimination in identifying small lesions and other conditions. There were no significant correlations between rDOI and the time between biopsy and MRI or between MRI and surgery. CONCLUSIONS: The correlation between rDOI and pDOI is significant, but rDOI is ineffective in predicting malignancy and other conditions. Axial T2-weighted images using 1.5T MRI provide the closest approximation of pDOI.

Cochlear Implantation in Inner Ear Malformations: Considerations Related to Surgical Complications and Communication Skills.

INTRODUCTION: There are particular challenges in the implantation of malformed cochleae, such as in cases of facial nerve anomalies, cerebrospinal fluid (CSF) leaks, erroneous electrode insertion, or facial stimulation, and the outcomes may differ depending on the severity of the malformation. The aim of this study was to assess the impact of inner ear malformations (IEMs) on surgical complications and outcomes of cochlear implantation. METHODS: In order to assess the impact of IEMs on cochlear implant (CI) outcomes, 2 groups of patients with similar epidemiological parameters were selected from among 863 patients. Both the study group (patients with an IEM) and control group (patients with a normal inner ear) included 25 patients who received a CI and completed at least 1 year of follow-up. Auditory performance, receptive and expressive language skills, and production and use of speech were evaluated preoperatively and at least 1 year after implantation. Types of surgical complications and rates of revision surgeries were determined in each group. RESULTS: In the study group, the most common malformation was an isolated enlarged vestibular aqueduct (EVA) (44.8%). Overall, the patients with IEMs showed significant improvement in auditory-verbal skills. In general, the patients who had normal cochleae scored significantly better compared to patients with IEMs (p < 0.05). The complication rate was significantly lower in the control group compared to the study group (p = 0.001), but the rate of revision surgeries did not differ significantly (p = 0.637). CONCLUSION: It is possible to improve communication skills with CIs in patients with IEMs despite the variations in postoperative performances. Patients with EVA, incomplete partition type 2, and cochlear hypoplasia type 2 were the best performers in terms of auditory-verbal skills. Patients with IEMs scored poorly compared to patients with normal cochleae. CSF leak (gusher or oozing) was the most common complication during surgery, which is highly likely in cases of incomplete partition type 3.

Assessment of olfactory and gustatory functions in COVID-19 patients

Background/aim: This study aims to evaluate of olfactory and gustatory functions of COVID-19 patients and possible risk factors for olfactory and gustatory dysfunctions. Materials and methods: The cross-sectional study included adult patients who were diagnosed with COVID-19 in Gazi University Hospital between April 2020 and June 2020. Volunteered patients participated in a survey in which olfactory and gustatory functions and various clinical information were questioned. Sinonasal Outcome Test-22 was also administrated to all patients. Results: A hundred and seventy-one patients participated in this study. Olfactory and gustatory dysfunctions rates were 10.5% (n: 18) and 10.5% (n: 18), respectively. Patients without any symptom other than smell and taste dysfunctions were clustered as group 1 and patients who are clinically symptomatic were clustered as group 2. Olfactory dysfunction occurred in 8% of group 1 and 17.4% of group 2 (p = 0.072). Gustatory dysfunction rate of smokers was 19.7% and significantly higher than gustatory dysfunction rate of nonsmokers (5.5%) (p = 0.007). Twenty-seven-point-eight percent of the patients with olfactory dysfunction (n = 5) were male and 72.2% (n: 13) were female. Sex did not show significant effect on rate of olfactory dysfunction. Twenty-five patients participated in psychophysical olfactory function test. No participant reported olfactory dysfunction at the time of test. Of the participants, 64% (n: 16) were normosmic and 36% (n: 9) were hyposmic according to Sniffin' Stick test. Conclusion: Olfactory and gustatory dysfunctions are more common in patients who are clinically symptomatic than those diagnosed during contact tracing. Objective tests may show that frequency of olfactory dysfunction is greater than frequency of self-reported olfactory dysfunction.

The role of gold weight implants in the management of paralytic lagophthalmos.

BACKGROUND: The study aims to evaluate the usage of gold weight implants and monitor complaints and comfort of patients. METHODS: A hundred and ninety-one implantations performed between January 2009 and January 2019 were analyzed. Seventy-eight patients included in this study The average age of the patients was 51.3 ± 14.5 years. Forty-five (57.7%) of them were male and 33 (42.3%) female. Patient satisfaction was measured with a questionnaire containing the most common complaints related to gold weight in the literature through telephone surveys. RESULTS: The average follow-up time was 74.5 months. Ninety-three-point-five percent of subjects had operational causes, among which the most widespread was acoustic neuroma (44.9%). The average time between facial paralysis and implantation was 141.1 days. Implantation was performed 26.6 days on average after acoustic neuroma surgery and 3.2 days on average after temporal zone malignancy surgery. Thirty-eight patients had their implants removed over either complication (n = 14) or recovery (n = 24). Recovery was the fastest after facial nerve decompression (mean= 4.75 ± 3.6 (2-10) months) and the slowest after 7-12 cranial nerve transfer (mean= 18.3 ± 8.2 (3-31) months). Twenty-six-point-nine percent (n = 21) of patients had complications, of which the most common was extrusion (n = 10). The overall satisfaction rate was 88.5% with the highest in visual acuity and the lowest in continuous requirement for artificial tear. DISCUSSION: The gold weight implantation is an effective, reversible, and easy procedure significantly reducing complaints regarding paralytic lagophthalmos. Early implementation may be beneficial for ocular complications. A dynamic facial reanimation could terminate need of implant.

Evaluation of Caldwell-Luc Operation in the Endoscopic Era: Experience From Past 7 Years.

PURPOSE: We wished to draw attention to the changes in the surgical method and indications for the Caldwell-Luc (CL) operation in the endoscopic era. PATIENTS AND METHODS: The patients who had undergone the CL operation in the previous 7 years were included in the present study. All operations had been performed by otolaryngologists. The CL operation was performed as 2 types of antrostomy: radical canine fossa antrostomy (RA) and mini-canine fossa antrostomy (MA). The surgical methods were grouped as follows: RA alone, endoscopic sinus surgery (ESS) plus RA, and ESS plus MA. RESULTS: RA alone, ESS plus RA, and ESS plus MA had been performed in 24 (25.5%), 6 (6.3%), and 64 (68.1%) patients, respectively. RA had been used for a total of 30 patients and had been combined with ESS for only 6 patients. The indications were categorized as mucosal sinus disease and odontogenic lesions. A statistically significant difference was found between the rates of the preferred antrostomy type for the treatment of sinus mucosal disease and odontogenic lesions (P < .001). CONCLUSIONS: In otorhinolaryngology practice, the CL procedure has mostly been required to provide easy access to the maxillary sinus when ESS alone would be inadequate. However, the formal CL operation, including RA, could still be considered a main surgical technique in oral and maxillofacial surgery practice.

Impact of the demographic and aetiological factors and intraoperative findings on postoperative outcomes in chronic otitis media surgery

Background/aim: Surgical success is related with many factors belonging to both the patient and the disease. This study aims to analyse the preoperative and intraoperative characteristics, the postoperative results, and the factors affecting the surgical success in different types of chronic otitis media (COM). Materials and methods: A total of 1510 ears of 1398 patients who underwent COM surgery were included in the study. Postoperative results were obtained from 376 ears of 356 patients who had been followed after surgery. The demographic characteristics of the patients, such as age and sex, operative findings, preoperative audiological examination results, and final audiometric and otoscopic examination findings, were retrospectively obtained from the archives of the department. Results: The most frequent diagnosis was simple COM (39.9%), and the most frequently performed surgery was tympanoplasty without mastoidectomy (46.6%). The overall hearing success rate was found to be 75.8%. Postoperative hearing success was significantly associated with the chronic otitis subgroup, ossicular pathologies, and the condition of the middle ear mucosa. Postoperative graft take rate was found to be 78.6%. Graft success was statistically significantly higher in patients with normal middle ear mucosa. Performing mastoidectomy, the presence of patency in aditus ad antrum, and being a paediatric case had no impact on graft success. Conclusion: Factors affecting the success of COM surgery include age, chronic otitis subgroup, location and size of perforation, the condition of the middle ear mucosa, and the level of the ossicular disease. These factors should be known and an appropriate treatment plan should be prepared.

Canal wall down versus canal wall up surgeries in the treatment of middle ear cholesteatoma

Background/aim: To compare outcomes of canal wall up (CWU) and canal wall down (CWD) techniques in the treatment of middle ear cholesteatoma. Materials and methods: Medical records of 76 patients who had a primary surgery due to middle ear cholesteatoma between July 2015 and November 2017 were reviewed retrospectively. Hearing thresholds, speech discrimination scores (SDS), recurrences, and revision surgeries of CWU and CWD surgeries were compared. Results: Of 76 cholesteatoma cases, 40 (52.6%) had a CWU and 36 (47.4%) had a CWD operation. Postoperatively, the mean air conduction thresholds were significantly better in CWU compared to CWD surgeries (P = 0.016). The presence of the stapes and the type of reconstruction material used did not have a significant effect on auditory success rates (P = 0.342 and P = 0.905, respectively). Auditory success was affected by the status of the middle ear mucosa as well. The recurrence and revision rates did not differ between the surgical techniques (P > 0.05). Conclusion: Status of the middle ear mucosa and external auditory canal are important factors affecting the outcomes in cholesteatoma. Instead of a CWD surgery, a CWU surgery seems applicable in cases of cholesteatoma when the bone in the external auditory canal is not eroded by the disease.

Assessment of Cochlear Implant Revision Surgeries in a Cohort of 802 Patients.

OBJECTIVE: To assess the etiology, demographics, rates and outcomes of revision surgeries, and device survival rates after cochlear implantation. STUDY DESIGN: Retrospective case review. SETTING: Tertiary Otology & Neurotology center. PATIENTS: Cochlear implantees who received revision surgeries after implantation INTERVENTIONS:: Any surgical intervention, performed due to device failure or the major complications of cochlear implantation. MAIN OUTCOME MEASURE: Medical records of the patients who received cochlear implants (CIs) between July 2002 and March 2018 were reviewed retrospectively regarding postoperative complications. Demographic data, device survival rates, and causes of revisions were recorded. RESULTS: Totally, 924 implantations were performed in 802 patients. Eighty one (8.7%) of them underwent 102 revision surgeries. The most common causes of revision surgeries were device failures and flap related problems which were seen in 28 and 18 patients, respectively.Overall CI survival rate was 91.9% in a 10 years period, which remained almost stable after 10 years. Although age was not found to be related with device failure (p = 0.693), device loss rates were significantly higher in adult implantees than children (p = 0.006). CONCLUSION: Device failure seems the most common cause of revision. The revision surgeries are usually safe and help to resolve the problem although flap problems are the most difficult to treat and may necessitate multiple revision surgeries. The device failure rate may reach to a plateau after 6 years. Overall CI survival rate exceeds 90% in 10 years period, and then remains stable.

The Management of the Paranasal Sinus Osteomas.

OBJECTIVE: Osteoma is the most common benign tumor of the paranasal sinuses. The clinical characteristics and treatment of this disease remain controversial. The aim of this study is to determine the appropriate method of treatment approach according to the features of osteomas. METHODS: Forty-one patients with paranasal sinus osteomas were included in the study. According to the location and the size of tumors, patients were followed up or operated. Surgical treatment was performed via external, endoscopic, or combined approaches for symptomatic patients. Routine physical and radiological evaluations were performed for follow-up in asymptomatic patients. RESULTS: Paranasal sinus osteomas were found most common in frontal sinus (n = 26, 63.4%) followed by ethmoid sinus (n = 10, 24.3%), maxillary sinus (n = 4, 9.7%), and sphenoid sinus (n = 1, 2.4%). Of the patients with frontal sinus osteomas, the endoscopic approach was performed in 11 patients, external approach (osteoplastic flap) in 9, and combined (external + endoscopic) approach in 5 patients. Endoscopic approach was preferred in all patients with ethmoid osteoma. The combination of Caldwell-Luc procedure and endoscopic approach was performed in 1 patient with maxillary sinus osteoma. In 3 patients, who underwent osteoplastic flap technique, mucocele developed in the postoperative period. Partial loss of vision developed postoperatively in 1 patient with a giant ethmoid osteoma. There were no other complications and recurrence in an average of 29 months follow-up. CONCLUSION: Paranasal sinus osteomas are rare, slow-growing benign lesions, with potentially serious complications. Main treatment option for sphenoid and ethmoid sinus and other symptomatic osteomas are surgical resection. Radiographic follow-up is necessary for asymptomatic lesions. Selection of surgical resection method depends on tumor location and size. Patients should be observed for recurrence with periodic examination and imaging techniques. Follow-up should be performed at least in 1-year intervals after the surgery. LEVEL OF EVIDENCE: 1c.

[Treatment approaches to temporal bone osteomas]. / Temporal kemik osteomlarinda tedavi yaklasimlari.

OBJECTIVES: This study aims to evaluate treatment approaches in relation to the localization, size and symptoms of temporal bone osteoma according to the complaints of the patient. PATIENTS AND METHODS: We retrospectively reviewed the records of 23 patients (16 males, 7 females; mean age 28.6 years; range 14-69 years) followed up with the diagnosis of temporal bone osteoma at our clinic between January 2005 and April 2016. We obtained the demographic features, clinical presentations (symptoms, location and size of the tumors), treatment approaches and postoperative outcomes of the patients from patients file. Treatment approaches were analyzed according to the characteristics of patients and of the tumor. RESULTS: The most common localization of osteomas was external auditory canal (66%), followed by mastoid bone (21%) and middle ear cavity (13%). The osteoma was detected incidentally in five patients out of 23. Treatment approaches were determined according to the presence of symptoms, size and localization of tumors. CONCLUSION: Physical examination and periodic follow-up is recommended in asymptomatic patients. In symptomatic patients, surgical resection is needed with an appropriate surgical approach based on the location and size of the tumor.

Value of Ultrasound Elastography in the Differential Diagnosis of Cervical Lymph Nodes: A Comparative Study With B-mode and Color Doppler Sonography.

OBJECTIVES: The purpose of this study was to determine the usefulness of ultrasound elastography in the evaluation of enlarged cervical lymph nodes in comparison with B-mode and color Doppler sonography. METHODS: A total of 220 lymph nodes in 168 consecutive patients who were referred for sonography of the neck were included in this study. B-mode sonograms were evaluated according to short-axis diameter, long-to-short-axis ratio, hilum, echogenicity, and microcalcification. For color Doppler sonography, 5 different patterns were defined according to vascularity. Elastographic patterns of the lesions were categorized to 5 main types. The mean strain index values were calculated for all lymph nodes. Histopathologic findings, clinical and laboratory data, and imaging findings were used as reference standards for the diagnosis of benign and malignant lymph nodes. RESULTS: Of the 220 lymph nodes, 69.5% were diagnosed as benign, and 30.5% were diagnosed as malignant. The sensitivity, specificity, and accuracy of B-mode sonography were 97.0%, 31.4%, and 51.3%, respectively; the values were 76.1%, 82.4%, and 80.5% for color Doppler sonography and 82.1%, 56.2%, and 64.1% for elastography. The strain index cutoff value for the differentiation of benign and malignant lymph nodes was accepted as 1.7. The sensitivity, specificity, and accuracy of the strain index were 71.6%, 76.5%, and 75.0%. CONCLUSIONS: Ultrasound elastography adds no additional value to combined B-mode and color Doppler sonography for differentiation of benign and malignant cervical lymph nodes.

Life Priorities in Head and Neck Cancer Patients Between Ages of 45 to 65.

Diseases in head and neck cancer patients and applied therapies according to former affect life quality to a higher extent. In this paper, life priorities in 49 patients with head and neck cancer who referred to Gulhane Military Medical Academy for diagnostic and therapeutic purposes and the relationship between these priorities and sociodemographic properties have been studied. Following life priorities have been observed more important for the patients: to communicate with people in social places, to eat without any help by themselves, external appearance, taste and odor sense, continuing sexual life. Other priorities have been observed less important for the patients: attending social activities like cinema and theater, swimming pool and sea sports, money required for check-ups, necessities like time. Besides, these necessities do not show dissimilarities to any significant extent according to sociodemographic properties of the patients.

Diagnostic utility of Stenger test: reappraisal of its value.

OBJECTIVE: Nonorganic hearing loss (NOHL) is a lack of consistency in audiological testing. Although NOHL is relatively rare, it is important to identify suspicious patients. This study was designed to evaluate the effectiveness of Stenger test and acoustic reflexes test (ART) in the evaluation of patients with suspicious of unilateral NOHL. STUDY DESIGN: A prospective study Methods: In this study, 474 adult patients with suspicious unilateral profound or total hearing loss were included. Pure tone audiometry (PTA), speech audiometry, Stenger test, ART and click-evoked auditory brainstem response (ABR) measurements were performed. The sensitivity, specificity and predictive values of the Stenger test and ART for unilateral, profound to total NOHL were assessed by comparing these with the results of ABR. RESULTS: The sensitivity and specificity of the Stenger test in verifying unilateral, profound hearing loss were 99% and 57%, respectively. The positive and negative predictive values of the test were 88% and 97%, respectively. The sensitivity and specificity of the ART in verifying unilateral, profound hearing loss were 96% and 60% at 1000 Hz and 98% and 60% at 2000 Hz, respectively. The positive and negative predictive values of the ART were 50% and 97% at 1000 Hz, and 75% and 97% at 2000 Hz, respectively. CONCLUSION: The Stenger test and ART are widely used for the evaluation of unilateral or asymmetrical NOHL. In our opinion, these tests are significantly powerful. More difficult cases require ABR to verify nonorganic hearing loss and to exclude specific diagnoses that may imitate NOHL.

[Pharyngocutaneous fistula rates after total laryngectomy in the organ preservation era]. / Organ koruma çaginda total larenjektomi sonrasi farengokütanöz fistül oranlari

OBJECTIVES: In this study, we aimed to determine and compare the pharyngocutaneous fistula (PCF) rates in patients undergoing primary total laryngectomy (TL) or those undergoing salvage TL following radiotherapy (RT)/chemoradiotherapy (CRT) failure. PATIENTS AND METHODS: Between January 2006 and January 2012, medical records of 91 male patients (mean age 61.0+10.3 years; range 36 to 88 years) who underwent TL in our clinic were retrospectively reviewed. RESULTS: Total laryngectomies were performed in 64 patients primarily and 27 of the patients as salvage TL following RT or CRT. Intraoperative mortality was 1.1%. Pharyngocutaneous fistula rates were 14.3%, 25.9%, and 17.8% in primary surgery group in patients with salvage laryngectomy following RT/CRT, and all groups, respectively. This difference was not statistically significant (p>0.05). The mean of PCF beginning time in primary surgery and salvage surgery patients were 19.0 and 12.7 days respectively. The mean time to recovery was 31.6 in primary surgery group and 60.0 days in salvage surgery group. When the beginning time of the fistula and recovery time were compared, the difference was also not statistically significant (p>0.05). CONCLUSION: Despite the lack of any statistically significant difference in our study, we found that post-TL PCF following RT/CRT occurs almost two times more frequently with earlier symptom onset and late recovery, compared to those undergoing primary surgery.

Characteristics and management of intractable neck involvement in tularemia: report of 19 patients.

The objective of this study is to determine the clinical characteristics and to evaluate the treatment options of intractable neck involvement in tularemia. The medical records of 19 tularemia patients with neck involvement were reviewed retrospectively. On physical examination, fluctuation indicating an abscess formation was detected in 78.9% of the patients. Bilateral involvement was seen in 15.8% of the patients. The most common clinical form was glandular form (63.1%). The most commonly involved lymph node group was upper jugular nodes (78.6%). Six patients underwent incision and drainage procedure, five patients underwent superselective neck dissection and eight patients had only medical treatment. Complete and immediate cure, and better tissue healing with less scarring could be achieved in all patients who underwent superselective neck dissections. In conclusion, intractable neck masses and an abscess can be the initial finding in tularemia, and a high index of suspicion is needed in the differential diagnosis. Superselective neck dissection is a safe and effective option in the treatment of long lasting cervical tularemia unless it responds to medical treatment.
