Surgery is the preferred treatment of benign parotid lesions, but it carries a risk of complications. Therefore, the approach toward the surgery of these lesions should seek to avoid complications. There are no guidelines or recommendations for when not to operate. Integration of comorbidities and other factors shift the scales from surgery toward observation in a small subset of patients presenting with parotid tumors. When observation is chosen, the patient should be followed frequently and cautiously, and the surgeon should be prepared to change strategy to surgical excision if in doubt.

Introduction Endoscopic endonasal surgery (EES) has become the preferred approach for pituitary tumor resection. Nevertheless, research on quality of life related to pituitary adenoma surgery is scarce. Objective The aim of the study is to evaluate short-term quality of life in patients after endoscopic endonasal resection of pituitary tumors and to find predictors for poor quality of life (QOL) outcome. Materials and Methods A prospective cohort study was conducted, including all patients who underwent EES for pituitary tumors in a tertiary medical referral center. Recruited patients completed the Anterior Skull Base Disease-Specific QOL (ASBS-Q) questionnaire and the Sinonasal Outcome Test 22 (SNOT-22) questionnaire before surgery, 2 and 4 to 6 months after surgery. Demographic and clinical data was collected. Results Our study included 49 patients. The overall ASBS-Q scores significantly improved 4 to 6 months after surgery (4.46 vs. 4.2, p Conclusion We found that patients after EES reported improved QOL 4 to 6 months post surgery. Specific improvement was noted in the QOL related to pain and vitality.

Introduction Isolated nasal obstruction (INO) is a common complaint of multiple etiology. The preoperative evaluation of patients presenting with nasal obstruction and deviated nasal septum (DNS) does not typically include imaging. The benefits of performing computed tomography (CT) in the preoperative setting are inconclusive. Objective Assessing the contribution of preoperative CT to the surgical treatment of non-sinusitis patients presenting with INO and DNS. Methods A retrospective cohort study on patients referred to surgery for nasal obstruction due to DNS or turbinate hypertrophy between 2006 and 2015. Data was retrieved from patients' medical charts. The CT scans and clinical data were reassessed by a second surgeon blinded to the patients' clinical course. Results Seventy of the 843 patients (8.06%) who underwent endoscopic sinonasal procedures during the study period had presented with INO and met the inclusion criteria. Thirty-eight (55.88%) of them underwent CT scans during their preoperative assessment. Modification of the initial preoperative planning based on the radiological findings was required in 32 cases (84.2%). When reassessed by a second blinded surgeon, 58% of cases required surgical modification rather than classical submucosal resection of nasal septum and turbinate reduction (P = 0.048). Conclusion Computed tomography was found beneficial in the preoperative planning for patients with INO. The original surgical plan based upon physical examination findings was modified based on radiological findings in 84.2% of the patients.

Inferior turbinate hypertrophy (ITH) and nasal septum deviation are leading causes of chronic nasal obstruction. Radiofrequency ablation (RFA) of hypertrophic inferior turbinates is effective for improving quality of life (QOL). We aim to assess QOL among patients with nasal obstruction associated with ITH and major deviated nasal septum.A prospective cohort study comparing the difference in improved QOL among patients with and without septal deviation following RFA treatment between March 2016 and June 2019. The patients formed two groups according to their grade of septal deviation. Patients participating filled in QOL questionnaires (Sino-Nasal Outcome Test-22 [SNOT-22] and Nasal Obstruction Symptom Evaluation [NOSE]) Pre- and 2 months postprocedure.All patients demonstrated QOL improvement with no significant difference between those with and those without any degree of deviated septum, as demonstrated by their responses to the SNOT-22 questionnaire (We conclude that septal deviation to certain degree does not preclude treatment of ITH with RFA nor does it negatively affect subjective improvement of the patient's QOL. Both those with and those without septal deviation will benefit similarly with regards to subjective QOL improvement.

Acute supraglottic laryngitis (ASL) is manifested by supraglottic inflammation that has the potential for rapid and fatal airway obstruction. Complete/incomplete vocal fold immobility (VFIm) in the setting of ASL may contribute to airway obstruction. The rate of VFIm complicating ASL is not known, and it is not clear whether its occurrence alters the course and the management of ASL, particularly the need to secure the airway (by endotracheal intubation/tracheostomy). This study seeks to describe the natural history of VFIm associated with ASL (ASLIm) and to determine the added effect of VFIm on ASL severity, management, and the need for intervention to secure the airway. This is a retrospective cohort study in a tertiary referral center. The medical records of all patients hospitalized due to ASL between January 2007 and December 2016 were reviewed. Of the 214 patients admitted due to ASL, VFIm was identified in 9 (4.2%). The VFIms resolved within 1–90 days in all 8 patients with available follow-up of 1–3 months. One patient required endotracheal intubation. The 9 ASLIm patients had significantly higher rates of hoarseness and a history of diabetes mellitus. There was no group difference in the need to secure the airway. VFIm is an apparently uncommon finding among patients with ASL. It appears to be usually transient, short-lasting, and full recovery can be expected. VFIm did not alter the ASL course, nor did it put our patients at increased risk for the need for intervention to secure the airway. 4.

Objective: The presence of clinically detectable papillary thyroid carcinoma (PTC) metastases in the lateral neck is an indication for neck dissection (ND) and thyroidectomy. Although there is a consensus regarding the importance of therapeutic selective ND of involved levels II to IV in patients with clinically evident locoregional metastatic disease, the prognostic benefit of level V prophylactic ND remains debatable. Methods: All patients who underwent thyroidectomy with ND for metastatic PTC between 2006 and 2019 were included in a single-institution retrospective study. Preoperative characteristics at initial presentation, imaging workup, intraoperative findings, and the final histopathological reports were retrieved from the institutional database. Results: A total of 189 patients with locally advanced PTC were identified, of whom 22 (11.6%) patients underwent therapeutic selective ND at levels II to IV together with level V dissection due to clinical involvement. Comparison of the patients who were operated on level V to those who were not revealed no significant difference. The disease recurrence rate was 20.1% throughout an average follow-up of 5.1±3.1 years. No significant differences in recurrence rate were found between patients who underwent and those who did not undergo level V ND (22.7% vs 19.8%, P = .648). No recurrence at resected level V was detected during follow-up, while recurrence at level V was found in 4 (2.1%) patients who did not undergo level V dissection. Evidence of macroscopic and microscopic extrathyroidal extension was significant predictors of disease recurrence risk. Conclusion: There were no significant associations between level V dissection and risk for recurrence. Recurrence at level V was rare (4/189 patients, 2.1%). Our study’s findings suggest a low prophylactic benefit of an elective level V ND. Elective level V ND should not be done routinely when lateral ND is indicated but should rather be considered after careful evaluation in high-risk patients.

BACKGROUND: After diagnosing well-differentiated thyroid cancer (WDTC), assessment of the risk for disease-specific recurrence is essential for deciding between hemi-thyroidectomy (HT) and total thyroidectomy (TT). The American Thyroid Association (ATA) 2015 guidelines suggest that patients with 1–4 cm WDTC without suspicious features may be suitable for HT. Patients’ preoperatively determined risk levels are re-stratified according to surgical and final histopathological findings. The incidence and clinical implications of high-risk features discovered postoperatively in patients with preoperatively determined low-risk WDTC are yet to be better defined. METHODS: Thyroidectomies performed in the Tel-Aviv Sourasky Medical Center (TASMC) [2006–2018] were included. Patients with 1–4 cm WDTC without evidence of positive cervical lymph nodes, invasion to adjacent structures, or high-risk cytology were considered at low risk for disease-specific recurrence—suitable for lobectomy. Patients were stratified according to their risk for disease-specific recurrence, pre- and postoperatively, and the rate of completion thyroidectomy was determined. RESULTS: In total, 301 (21%) patients were preoperatively stratified as low risk. Forty-six of them (15%) were re-stratified postoperatively as intermediate-to-high-risk. There were no significant differences in the characteristics of the patients who maintained their original stratification to patients who were upscaled to a higher risk level postoperatively. CONCLUSIONS: We report a 15% rate of postoperative risk escalation of patients who required completion thyroidectomy according to current ATA guidelines. In our opinion, this rate of postoperative WDTC upscaling of risk requiring more radical surgery than originally planned, is acceptable. Meticulous preoperative personalized evaluation by an experienced multidisciplinary dedicated team is essential.

Background Papillary thyroid cancer (PTC) usually metastasizes via lymphatic channels in a sequential fashion, first to the central compartment, followed by the lateral neck. PTC patients diagnosed with lateral neck disease (N1b) without proof for central involvement traditionally undergo prophylactic central neck dissection (pCND). However, substantial evidence on outcomes to support this approach is lacking. Materials and methods We conducted a dual center retrospective study to compare the rate of central neck recurrence between N1b PTC patients undergoing pCND and those spared pCND. All patients diagnosed with N1b PTC who underwent total thyroidectomy and lateral neck dissections with or without pCND between January 1998 and December 2015 were included in this study. The rates of central neck recurrences were compared between the groups. Results The 111 patients who met the inclusion criteria were 44 females (39.6%) and 67 males (60.4%), with a mean age of 50.2 ± 17.7 years, and a mean follow-up of 10.2 ± 5.3 years. Sixty patients (54.1%) underwent a pCND and 51 patients (45.9%) did not (non-pCND). During follow-up, 18 patients (16.2%) had level VI recurrences, 13 in the pCND group and 5 in the non-pCND group. Cox-regression models with propensity scoring did not reveal any inclination or an advantage for performing pCND. Conclusion The present study demonstrated no advantage in performing pCND to prevent central neck recurrence among PTC patients with lateral neck involvement only. These findings question the need for pCND in patients without clinical evidence of central neck disease.

Reconstruction of surgical defects by free tissue transfer following resection of head and neck tumors in children are sparse. This study aims to assess the feasibility and safety of free flap reconstruction following surgical ablation of head and neck and skull base tumors in children based on our experience and the recent literature.Data from medical files of all children and adolescents18 years of age who underwent free flap reconstruction following resection of head and neck and skull base tumors at our tertiary center between 2000 and 2018 were retrospectively reviewed. Data on early and late complications at the primary and donor sites, functional and aesthetic outcome, and tumor control were analyzed.Twenty-four children (mean age 11.3 ± 5.1 years) were enrolled. Early complications occurred in 14 (56%) and late complications occurred in 8 (32%) of the procedures, with surgical intervention required in 4 (16%). Prior chemoradiation, sarcoma, non-reanimation procedures, and the use of rectus abdominis free flaps were associated with higher complication rates. The final functional and cosmetic outcomes, including mastication, deglutition, and speech, were satisfactory in all patients with one exception.Free flap transfer is a safe and feasible technique for reconstructing head and neck and skull base defects following surgical excision of tumors in children. Early identification and precautionary measures against the effects of potential causes of complications may improve outcome. Larger international cohort studies are warranted.

Objectives Despite its technical feasibility, anterior skull base surgery still carries the risk of severe postoperative complications, morbidity, and mortality. The reported rate of complications has diminished over the past two decades, but they continue to pose various challenges. This study aims to report late complications in a relatively large series of patients who underwent open anterior skull base surgery, and to propose methods for averting such complications. Methods Retrospective chart review of all patients who underwent anterior open skull base surgery between 2000 and 2016 in a university-affiliated tertiary referral cancer center. Results There were 301 operations, of which 198 (65.8%) were for benign disease and 103 (34.2%) were for malignant tumors. The male-to-female ratio was 1.4:1, and the mean age was 44.8 years. Delayed complications occurred in 85 patients (28.2%): 31 (10.3%) involved wounds, 18 (13.9%) involved the central nervous system, and 14 (4.6%) involved the orbit. Multivariate analysis found malignant pathology, intracranial extension, and previous radiochemotherapy as predictors for the development of a delayed complication. The patients who were operated in the later study period (after 2007) had lower rates of all three types of complications compared with the earlier study period. Conclusion Delayed complications following skull base surgery are in decline. This is mainly due to the advancement in imaging studies, surgical techniques, development of sophisticated reconstructive procedures, and the cooperation of multidisciplinary teams. We attribute the reduction in our department to our revised treatment protocol which is presented herein, with emphasis on averting the occurrence of these complications. Level of Evidence The level of evidence is 4.

Objectives/hypothesis Anterior skull base operations pose the risk for postoperative cerebrospinal fluid (CSF) leak. Routine lumbar continuous drainage catheter (LD) placement is intended to decrease CSF leaks and central nervous system (CNS) complications, but there are no sound evidence-based data on its efficacy. The primary goal of this study was to review CNS complications following anterior open skull base surgery and their association with LD placement. The secondary goal was to define predictors for the development of early CNS complications. Study design Retrospective case series. Methods We conducted a retrospective analysis of all patients who underwent anterior skull base surgery between 2000 and 2016 at the Tel Aviv Sourasky Medical Center, an Israeli tertiary referral center. Results A total of 226 patients underwent open skull base surgery, of whom 118 had elective perioperative continuous LD insertion and 108 did not. Delayed complications were defined as those occurring more than 30 days after the index operation. Thirty-one (26%) patients in the LD group had early CNS complications compared with only two (1.6%) in the non-LD group, whereas 13 (11%) of the former patients had late CNS complications compared with four (3%) of the latter patients. Early systemic and late wound complications were also significantly more numerous in the LD group. On multivariate analysis, elective LD insertion and intracranial tumor extension were found to be predictors for developing early CNS complications. Conclusions The placement of continuous LDs might increase the risk of developing early and late CNS complications after open anterior skull base surgery.

Introduction: Several surgical procedures have been described for the treatment of respiratory distress secondary to vocal fold immobility (VFI), but the contribution of posterior cordotomy (PC) to tracheostomy weaning or prevention has not been studied in depth, particularly in the acute setting. The objective of this study was to show the effectiveness of PC to relieve dyspnea, prevent the need for tracheostomy, and enable decannulation in patients with VFI. Methods: We conducted a retrospective study and reviewed the medical records of all patients whose dyspnea warranted surgical intervention from January 2013 to January 2018. Data were retrieved on epidemiology, etiology, and duration of VFI, tracheostomy dependence, success in decannulation from tracheostomy or respiratory relief, number of procedures until decannulation, and complications. Results: Twelve suitable patients were identified of whom eleven had bilateral VFI and one had unilateral VFI. Five were tracheostomy-dependent. Ten patients underwent unilateral PC, and two patients underwent bilateral PC. All the patients experienced respiratory relief, eleven after a single PC and one after two PCs. All tracheostomy-dependent patients were decannulated. The mean follow-up after PC was 24.55 months during which none of the patients required a re-tracheostomy and three patients required revision of the PC. There were no surgical complications. Postoperatively, eight patients (67%) experienced a breathy voice and three patients (25%) had dysphagia for fluids. No patient had aspiration pneumonia. Conclusions: We conclude that PC is an easy, safe, and effective procedure for tracheostomy weaning and respiratory relief in patients with VFI. A revision PC may be indicated in some patients. A breathy voice is to be expected, and a few patients will experience dysphagia to fluids that may be addressed by instructing the patient to use a fluid thickener and take small sips.

Introduction The steady increase in average life expectancy has led to a rise in the number of referrals of elderly patients for major operations. It is not clear whether age itself is a risk factor for morbidity and mortality after skull base operations. We investigated a possible link among a cohort of patients older than 80 years of age who underwent those surgeries in our department. Methods We conducted a retrospective analysis of all patients who underwent skull base surgery at the TASMC (Tel Aviv Sourasky Medical Center) between 2000 and 2016. Results A total of 369 patients underwent open skull base surgeries in our institution, and 13 were patients older than 80 years. The median age of the octogenarians was 83.4 (range 80–89), and the male-to-female ratio was 7:6. Twelve patients had major systemic comorbidities. Four patients had major complications associated with surgery: three had early wound complications, and one each had early central nervous system complications, early and late systemic complications, and late orbital complications. This complication rate is comparable to that of our younger group of 356 patients. The overall survival rate was measured for 30 days, 1 year, and 3 years, and it was not significantly different between the octogenarians and that of the younger patients. Further comparison of the elderly group with 13 matched younger patients revealed no difference of morbidity and mortality between the two groups. Conclusions Despite their systemic comorbidities, the morbidity and mortality rates associated with skull base surgery in octogenarians appear to be comparable to that of younger patients undergoing the same procedures.

Objective Reconstruction after open surgery of anterior skull base lesions is challenging. The fascia lata graft is our workhorse for achieving dural sealing and preventing cerebrospinal fluid leak and meningitis. This study seeks to analyze the donor and recipient site complication rates after fascia lata reconstruction. Methods This is a retrospective review of all open anterior skull base operations in which a double-layer fascia lata graft was used for the reconstruction of the defect from 2000 to 2016 at the Tel-Aviv Sourasky Medical Center, a tertiary referral center in Israel. Results Of the 369 patients operated for skull base lesions, 119 underwent open anterior skull base surgery and were reconstructed with a fascia lata graft. The patients' mean age was 47.1 years, and 68 (57.1%) were males. The overall postoperative early and late donor site complication rates were 6.7% (n = 8) and 5.9% (n = 7), respectively. Multivariate analysis found minor comorbidities and persistent/recurrent disease as being predictors for early-term complications. The overall postoperative early central nervous system (CNS) complication rate was 21.8% (n = 26), while 12.6% (n = 15) of the patients had late postoperative CNS complications. Conclusion Reconstruction of open anterior skull base lesions with fascia lata grafting is a safe procedure with acceptable complication and donor site morbidity rates.

Purpose Acute supraglottitis (SG) can potentially lead to rapid airway obstruction. The last few decades have witnessed a shift towards a more conservative approach in airway management of adult SG. This study aims to evaluate this watchful approach based on a large case series combined with a high-level meta-analysis of all reports in the English literature. Methods Retrospective case series and meta-analysis. The medical records of all adult patients diagnosed as having SG who were hospitalized in a large-volume tertiary referral center between January 2007 and December 2018 were reviewed. A meta-analysis was conducted on all English literature published between 1990 and 2018. Results A total of 233 patients (median age 49.1 years, 132 males), were admitted due to acute SG during the study period. No airway intervention was required in 228 patients (97.9%). Five patients (2.1%) required preventive intubation, and two of them (0.9%) were later surgically converted to a tracheotomy. Patients who required airway intervention had higher rates of diabetes (P = .001), cardiovascular diseases (P = .036) and other comorbidities (P = .022). There was no mortality. The meta-analysis revealed that the overall intubation rates random effects model was 8.8% [95% confidence interval (CI) 4.6%–14.0%] and that the tracheotomy random effects model was 2.2% (95% CI; 0.5%–4.8%). The overall mortality rate was 0.89%. Conclusions This study provides evidence of low rates of surgical airway intervention in patients diagnosed with SG worldwide. A conservative approach in adult SG is safe and should be advocated. Level of evidence: 2.

Introduction Skull base lesions in children and adolescents are rare, and comprise only 5.6% of all skull base surgery. Anterior skull base lesions dominate, averaging slightly more than 50% of the cases. Until recently, surgery of the anterior skull base was dominated by open procedures and endoscopic skull base surgery was reserved for benign pathologies. Endoscopic skull base surgery is gradually gaining popularity. In spite of that, open skull base surgery is still considered the “gold standard” for the treatment of anterior skull base lesions, and it is the preferred approach in selected cases. Objective This article reviews current concepts and open approaches to the anterior skull base in children in the era of endoscopic surgery. Materials and Methods Comprehensive literature review. Results Extensive intracranial–intradural invasion, extensive orbital invasion, encasement of the optic nerve or the internal carotid artery, lateral supraorbital dural involvement and involvement of the anterior table of the frontal sinus or lateral portion of the frontal sinus precludes endoscopic surgery, and mandates open skull base surgery. The open approaches which are used most frequently for surgical resection of anterior skull base tumors are the transfacial/transmaxillary, subcranial, and subfrontal approaches. Reconstruction of anterior skull base defects is discussed in a separate article in this supplement. Discussion Although endoscopic skull base surgery in children is gaining popularity in developed countries, in many cases open surgery is still required. In addition, in developing countries, which accounts for more than 80% of the world's population, limited access to expensive equipment precludes the use of endoscopic surgery. Several open surgical approaches are still employed to resect anterior skull base lesions in the pediatric population. With this large armamentarium of surgical approaches, tailoring the most suitable approach to a specific lesion in regard to its nature, location, and extent is of utmost importance.

Objective The endoscopic endonasal approach is being increasingly used for the resection and reconstruction of anterior skull base (ASB) lesions. Vascularized nasoseptal flaps (NSF) have become the workhorse for the reconstruction of ASB defects, resulting in a significant decrease in the incidence of cerebrospinal fluid (CSF) leaks. The objective of this study was to investigate the efficacy and safety of NSF in children. Methods This is a retrospective analysis of the medical records of all patients under the age of 18 years who underwent endoscopic repair of ASB lesions with the use of NSF at our tertiary medical center between 1/2011 and 8/2016. Results Twelve children underwent ASB defect repair for both benign and malignant neoplasms using the endoscopic endonasal NSF technique. Four children had previously undergone ASB surgery. The male-to-female ratio was 1:1, the average age was 12.3 years, the average hospitalization time was 8.3 days, and the maximum follow-up period was 24 months, during which craniofacial growth appeared to be unimpaired. A lumbar drain was used postoperatively in six cases. Crust formation and synechia were observed in two cases. There was one case of a major long-term complication (a CSF leak followed by meningitis). Conclusions Endoscopic endonasal NSF was both an effective and a safe technique for ASB defect reconstruction in 12 children for both benign and malignant neoplasms. It had a high success rate and a low complication rate. No apparent negative influence on craniofacial growth was observed in our series.
