RESUMEN
PURPOSE: To analyze the reason for the diversity of the clinical course of subglottic cysts and discuss their pre- and coexistence with subglottic stenosis. METHODS: The medical records of patients who were treated for subglottic cysts between 2003 and 2020 were retrospectively reviewed and direct laryngoscopy videos were analyzed to assess the healing patterns of their disease. RESULTS: Of the 15 patients, 10 had a history of intubation in the neonatal period. In 11 patients, the cysts were transparent and well defined, and no recurrence of subglottic cysts occurred after the initial surgery. In four patients, the cysts were located deep in the mucosa and did not have the typical appearance of a cyst, but rather of a stenotic segment; all of them had a history of intubation and three of them required laryngotracheal reconstruction. CONCLUSION: Transparent, thin-walled superficial subglottic cysts with healthy surrounding mucosa can easily be treated with endoscopic marsupialization; however, the treatment of deep subglottic cysts can be challenging. The coexistence of subglottic cysts and subglottic stenosis is not rare. We point out the need for considering the possibility of a missed deep submucosal cyst in a seemingly refractory case of pediatric subglottic stenosis with atypical endoscopic findings and with a background history of prior intubation.

INTRODUCTION: Lysyl oxidase-like 4 is an amine oxidase from the lysyl oxidase family that was previously shown to be overexpressed in head and neck cancer and upregulated in response to hypoxia. The possible role of lysyl oxidase-like 4 as a tumor marker in advanced stage larynx cancer was investigated. OBJECTIVE: To investigate the expression of lysyl Oxidase-Like 4 protein in advanced stage laryngeal cancer and elucidate its possible role as a tumor marker, predictor of treatment response and prognosticator. METHODS: Diagnostic specimens of 72 patients treated for stage III-IV laryngeal squamous cell carcinoma were evaluated for lysyl oxidase-like 4 expression by immunohistochemistry. RESULTS: Lysyl oxidase-like 4 expression was correlated with advanced tumor stage (pâ¯=â¯0.041) and better differentiation (pâ¯=â¯0.025) but was independent of tumor diameter (pâ¯=â¯0.456). Response to induction chemotherapy or the need for salvage laryngectomy were not affected by lysyl oxidase-like 4 expression (pâ¯=â¯0.999, pâ¯=â¯0.070 respectively). Increased lysyl oxidase-like 4 expression was associated with better 2 year overall survival in both univariate (pâ¯=â¯0.036) and multivariate analyses (pâ¯=â¯0.014). CONCLUSION: Lysyl oxidase-like 4 expression emerges with advancing stages, is lost with worsening differentiation, and may have tumor suppressive properties in larynx cancer.

We aimed to compare reverse transcription-polymerase chain reaction (RT-PCR) results of nasopharyngeal aspiration (NA) and nasopharyngeal swab (NS) samples in the diagnosis of coronavirus disease 2019. NS was obtained with a dacron swab and NA was performed by aspiration cannula. The sampling was performed by an otolaryngologist to ensure standardized correct sampling from the nasopharynx. RT-PCR was performed for the detection of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The level of agreement between the result of NA and NS samples for each patient was analyzed. The Ct values were compared. Thirty-three patients were enrolled in the study with a mean age of 56.3 years. Thirteen subjects resulted negative with both NS and NA; 20 subjects resulted positive with NA and 18 subjects resulted positive with NS. The mean values of Ct for NA samples and NS samples were 24.6 ± 5.9 and 24 ± 6.7, respectively. There was no statistical difference between Ct values of NA and NS samples (p = 0.48). RT-PCR for SARS-Cov2 performed with NA sample and NS sample showed a strong correlation regarding the positivity/negativity and the Ct values.

PURPOSE: Our study aimed to quantify the impact of submandibular gland (SMG) resection during Level I neck dissection (ND) on stimulated salivary output (SSO) and xerostomia-related quality of life in patients with head and neck cancer (HNC). METHODS: A retrospective cohort was formed from 32 patients that underwent unilateral or bilateral Level I ND and a control group of 23 patients that had level II-IV ND. SSO (Saxon test) and University of Washington Quality of Life survey results for both groups were compared. RESULTS: Mean SSO was 3.41 g in the SMG resection group and 3.86 g in the control group, with no significant statistical difference. There was no difference in mean SSO between patients with 2 SMGs, a single remaining SMG, or no glands. The mean SSO of SMG resection cases with a history of adjuvant RT was 2.61 g which was below the xerostomia threshold for the Saxon test (2.75 g) and control group patients with RT had a significantly higher mean SSO (4.07 g). The lowest UW-QoL saliva domain score average (53.8) was in the SMG-resected, RT-positive group. CONCLUSION: Results indicate unilateral or bilateral resection of SMG does not reduce SSO to a significant extent. Adjuvant radiotherapy and SMG resection are additive risk factors for xerostomia and the related loss in quality of life. SMG sparing may be necessary in HNC patients with higher risk for the need of adjuvant radiation.

BACKGROUND: We aimed to assess the feasibility and short-term clinical outcomes of surgical procedures for cancer at an institution using a coronavirus disease 2019 (COVID-19)-free surgical pathway during the peak phase of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic. MATERIALS AND METHODS: This was a single-center study, including cancer patients from all surgical departments, who underwent elective surgical procedures during the first peak phase between March 10 and June 30, 2020. The primary outcomes were the rate of postoperative SARS-CoV-2 infection and 30-day pulmonary or non-pulmonary related morbidity and mortality associated with SARS-CoV-2 disease. RESULTS: Four hundred and four cancer patients fulfilling inclusion criteria were analyzed. The rate of patients who underwent open and minimally invasive procedures was 61.9% and 38.1%, respectively. Only one (0.2%) patient died during the study period due to postoperative SARS-CoV2 infection because of acute respiratory distress syndrome. The overall non-SARS-CoV2 related 30-day morbidity and mortality rates were 19.3% and 1.7%, respectively; whereas the overall SARS-CoV2 related 30-day morbidity and mortality rates were 0.2% and 0.2%, respectively. CONCLUSIONS: Under strict institutional policies and measures to establish a COVID-19-free surgical pathway, elective and emergency cancer operations can be performed with acceptable perioperative and postoperative morbidity and mortality.

BACKGROUND: This study was planned (1) to evaluate long-term outcome after cochlear implantation in patients with post-meningitic deafness and (2) to compare the outcome measures with patients implanted for deafness due to other causes. METHODS: Records of 54 patients deafened as a sequel of bacterial meningitis and implanted at the largest university-based cochlear implant program in Turkey were retrospectively reviewed. Fifty-four age- and sex-matched patients with a similar interval of implant use were selected for controls. Surgical and long-term audiological outcome (in terms of categories of auditory performance-II scores) was assessed and compared. RESULTS: Twenty-seven (52%) patients had some degree of labyrinthitis ossificans and 19 of them had full electrode insertion via basal turn cochleostomy. Patients with and without labyrinthitis ossificans in the post-meningitic group had no difference in final categories of auditory performance-II score (P=.559). Median categories of auditory performance-II scores were 6 for post-meningitic group and 7 for controls, with a significant statistical difference (P < .001). Partial or full insertions did not differ in outcome (P=.938). Mean time to implantation was not correlated with the final categories of auditory performance-II score for the post-meningitic group (P=.695). CONCLUSION: Cochlear implant recipients deafened due to meningitis have a worse long-term hearing and speech performance as measured by categories of auditory performance-II than patients implanted for congenital deafness. The presence of labyrinthitis ossificans or the limited extent of electrode insertion produced overall results that were comparable with other cases.

Introduction. Treatment for bilateral vocal fold paralysis (BVFP) has evolved from external irreversible procedures to endolaryngeal laser surgery with greater focus on anatomic and functional preservation. Since the introduction of endolaryngeal laser arytenoidectomy, certain modifications have been described, such as partial resection procedures and mucosa sparing techniques as opposed to total arytenoidectomy. Discussion. The primary outcome measure in studies on BVFP treatment using total or partial arytenoidectomy is avoidance of tracheotomy or decannulation and reported success ranges between 90 and 100% in this regard. Phonation is invariably affected and arytenoidectomy worsens both aerodynamic and acoustic vocal properties. Recent reports indicate that partial and total arytenoidectomies have similar outcome in respect to phonation and swallowing. We use CO2 laser assisted partial arytenoidectomy with a posteromedially based mucosal flap for primary cases and reserve total arytenoidectomy for revision. Lateral suturing of preserved mucosa provides tension on the vocal fold leading to better voice and leaves no raw surgical field to unpredictable scarring or granulation. Conclusion. Arytenoidectomy as a permanent static procedure remains a traditional yet sound choice in the treatment of BVFP. Laser dissection provides a precise dissection in a narrow surgical field and the possibility to perform partial arytenoidectomy.

Renal cell carcinoma (RCC) metastatic to the head and neck region is quite rare. This report describes a case of RCC metastatic to the oral tongue presenting initially with a renal mass that evaded diagnosis by biopsy examination of the primary lesion and was eventually established as a papillary type RCC by lingual biopsy examination. The tongue mass progressed rapidly despite chemotherapy with interferon-α2b, caused difficulties with oral food intake, and thus necessitated removal by partial glossectomy. Treatment alternatives for lingual RCC metastasis include surgical resection for major functional impairment, risk of airway compromise, or massive hemorrhage. Radiotherapy might be useful and should be considered for specific patients. Lingual metastasis from RCC usually predicts poor survival.
