Patient preference for commonly-used, head and neck cancer-specific quality of life questionnaires in the follow-up setting (Determin): A multi-centre randomised controlled trial and mixed methods study.

BACKGROUND: Quality of life (QoL) assessment forms an integral part of modern cancer care and research. The aim of this study is to determine patients' preferences and willingness to complete commonly used head-and-neck cancer (HNC) QoL questionnaires (QLQs) in routine follow-up clinics. METHODS: This is a randomised control trial of 583 subjects from 17 centres during follow-up after treatment for oral, oropharyngeal or laryngeal cancer. Subjects completed three structured validated questionnaires: EORTC QLQ-HN35; FACT-HN and UW-QOL, and an unstructured patient-generated list. The order of questionnaire presentation was randomised, and subjects were stratified by disease site and stage. Patients self-rated the questionnaires they found most helpful to communicate their health concerns to their clinicians. RESULTS: Of the 558 respondents, 82% (457) found QLQs useful to communicate their health concerns to their clinician (OR = 15.76; 95% CI 10.83-22.94). Patients preferred the structured disease-specific instruments (OR 8.79; 95% CI 5.99-12.91), while the open list was the most disliked (OR = 4.25; 95% CI 3.04-5.94). There was no difference in preference by treatment modality. More women preferred the FACT-HN (OR = 3.01, 95% CI 1.05-8.62), and patients under 70 preferred EORTC QLQ-HN35 (OR = 3.14, 95% CI 1.3-7.59). However, only 55% of patients expressed preference to complete questionnaires routinely at the clinic. CONCLUSIONS: Most patients found QLQs helpful during their follow-up and 55% supported routine questionnaires in follow-up clinics. Males and people over 70 years old were the least willing to complete the routine questionnaires and preferred shorter questionnaires (e.g., UW-QOL). Women preferred FACT-HN, and younger patients preferred EORTC QLQ-HN35. Reasons for the reluctance to complete questionnaires require elucidation.

Impact on quality of life in obstructive sialadenitis predicting outcomes after sialendoscopy.

PURPOSE: Sialendoscopy is a minimally invasive procedure considered a paradigm shift in the treatment of obstructive sialadenitis. However, it shows an average need for revision procedure in up to 24% of operated cases. This study analyzed whether patient-related variables could predict the need for a revision during postoperative follow-up. METHODS: From 2012 to 2020, this prospective comparative study analyzed demographic data as well as preoperative responses to the "Manukau Salivary Symptoms Score" (MSSS) questionnaire as predictors of the need for a revision procedure due to symptoms recurrence. RESULTS: 188 sialendoscopies (39.4% for stones/60.6% for stenoses) in 112 parotid (59.6%) and 76 submandibular glands (40.4%) were included in this study. Forty patients (21.3%) required a revision procedure. The variable "Impact on quality of life" in the preoperative period of patients with sialoliths showed that the likelihood of a revision procedure increases by 33.6% with each increase in the 10-point Likert scale presented in the MSSS (p = 0.010, OR = 1336, CI = 1.071 to 1.667). This finding was not influenced by the location of the sialolith in the duct (p = 0.415), size (p = 0.058) or number of stones (P = 0.476). Other demographic variables related to the patient showed no association with the need of a revision procedure. CONCLUSION: Further studies should be performed to exclude the influence of other variables on the results; however, special attention should be given to patients who report a greater pre-operative impact on quality of life due to sialolithiasis. LEVEL OF EVIDENCE: II.

A systematic review of psychological interventions for patients with head and neck cancer.

AIM: The purpose of this systematic review is to identify psychological interventions that have been effective at improving quality of life and reducing psychological distress (depression and anxiety) in patients with head and neck cancer. METHODS: All relevant peer-reviewed articles published between March 1980 and March 2017 were identified through an electronic search of five databases: Medline, Embase, PsycINFO, Scopus, and Academic Search Complete. Risk of bias was independently assessed by two reviewers using the Crowe Critical Appraisal Tool (CCAT). Following this, a narrative synthesis of the findings was completed. RESULTS: Twenty-one unique intervention studies were identified. Interventions tested included cognitive behavioural therapy (CBT), psychoeducation, meditation/mindfulness, group therapy, and telehealth initiatives. Ten studies utilised a randomised controlled design. Five of these investigated CBT and three examined psychoeducation, with the greatest empirical support found for these intervention types. However, the majority of studies were underpowered to detect significant effects and did not examine whether improvements in quality of life and psychological well-being were sustained over time. CONCLUSIONS: Further research is needed to investigate the effects of psychological interventions among patients with head and neck cancer, using randomised controlled designs, adequately powered samples, and long-term follow-up. This would allow evidence-based recommendations to be made regarding the most appropriate interventions to implement in clinical practice. TRIAL REGISTRATION: CRD42017069851.

A Self-Regulatory Intervention for Patients with Head and Neck Cancer: Pilot Randomized Trial.

BACKGROUND: Research is yet to investigate whether psychological interventions delivered early after diagnosis can benefit patients with head and neck cancer (HNC). PURPOSE: The aim of this study was to investigate the effectiveness of a brief self-regulatory intervention (targeting illness perceptions and coping) at improving HNC patient health-related quality of life (HRQL). METHODS: A pilot randomized controlled trial was conducted, in which 64 patients were assigned to receive three sessions with a health psychologist in addition to standard care or standard care alone. Participants completed questionnaires assessing HRQL, general distress, and illness perceptions at baseline and again 3 and 6 months later. RESULTS: Compared to the control group, patients who received the intervention had increased treatment control perceptions at 3 months (p = .01), and increased social quality of life at 6 months (p = .01). The intervention was particularly helpful for patients exhibiting distress at baseline. CONCLUSION: A brief psychological intervention following HNC diagnosis can improve patient perceptions of treatment and social quality of life over time. Such interventions could be targeted to patients who are distressed in order to confer the greatest benefit. TRIAL REGISTRATION NUMBER: 12614000813684.

Illness perceptions and coping predict post-traumatic stress in caregivers of patients with head and neck cancer.

PURPOSE: There is evidence to suggest that caregivers of patients with head and neck cancer (HNC) are susceptible to post-traumatic stress disorder (PTSD) symptoms. The aim of this study was to investigate whether illness perceptions and coping strategies contribute to the development of these symptoms. METHODS: Seventy-eight caregivers completed questionnaires to assess distress, illness perceptions, and coping at diagnosis. Six months later, PTSD symptoms were assessed. Correlation and regression analyses were performed to examine relationships between illness perceptions and coping at diagnosis and PTSD symptoms at 6 months in 48 caregivers. RESULTS: Nineteen percent of caregivers met criteria for estimated PTSD caseness at 6-month follow-up. A regression analysis demonstrated that caregiver perceptions of low treatment benefit and many cancer symptoms, as well as use of avoidant coping techniques, predicted subsequent PTSD. CONCLUSIONS: This preliminary study suggests that caregivers who have perceptions of low benefits from treatment and many patient symptoms, and those using avoidant coping strategies, are at increased risk of experiencing symptoms of PTSD. Psychological interventions that target illness perceptions and coping may help to reduce the prevalence of PTSD in caregivers of patients with HNC.

Immunoglobulin G4-related disease of the orbital cavity, cervical lymph nodes and greater auricular nerve: case report.

IgG4-related disease (IgG4-RD) is a novel clinicopathological entity characterised by elevated tissue levels of IgG4-positive plasma cells. It can present in almost every organ systems. We present a case of a 48year-old man with recurrent intra-orbital and cervical lymph node swelling and found to have greater auricular nerve involvement intraoperatively during open surgical biopsy. Histopathological evaluation of biopsied specimens from these lesions yielded IgG4-positive plasma cell infiltration on immunohistochemistry. Key pathological features such as prominent lymphoplasmacytic population, storiform fibrosis and obliterative phlebitis were also seen. A diagnosis of IgG4-RD was made. Oral prednisone therapy ameliorated the symptoms and patient remained in remission at followup. Literature review indicated that IgG4-RD is a rare condition that seldom occurs concurrently in the orbital cavity, cervical lymph nodes and involving the greater auricular nerve. The condition may often masquerade as malignancy or infection due to formation of tumefactive lesions but tend to respond favourably to glucocorticoid or immunosuppressants. The differential diagnosis of unusual mass lesions in these locations should include IgG4-RD. The otolaryngologist, as well as other health professionals, should be familiar with this novel disease to ensure timely diagnosis and treatment.

Coping strategies predict post-traumatic stress in patients with head and neck cancer.

Evidence suggests that patients with head and neck cancer (HNC) are susceptible to post-traumatic stress disorder (PTSD). However, research is yet to examine predictors of PTSD symptoms in this patient group. The objective of this study was to investigate whether coping strategies at HNC diagnosis were related to outcomes of post-traumatic stress and health-related quality of life (HRQL) 6 months later. Sixty-five patients with HNC completed an assessment of coping, distress, and health-related quality of life at diagnosis and again 6 months later, and an assessment of post-traumatic stress at 6 months. Correlations and regression analyses were performed to examine relationships between coping and outcomes over time. Regression analyses showed that denial, behavioural disengagement and self-blame at diagnosis predicted post-traumatic stress symptoms. Self-blame at diagnosis also predicted poor HRQL. Results have implications for the development of psychological interventions that provide alternative coping strategies to potentially reduce PTSD symptoms and improve HRQL.

Observations of benefit finding in head and neck cancer patients.

The management of head and neck cancer (HNC) can lead to potentially severe physical, functional and psychological disturbances. As a result, many HNC patients develop symptoms of depression following diagnosis and treatment. Finding benefit in a disease and its treatment can reduce the symptoms of depression and enhance quality of life (QOL). 92 patients from the Head and Neck Cancer Clinic at Auckland Hospital completed measures of unmet needs and quality of life at diagnosis, and completed measures of benefit finding, coping, fear of recurrence and depression 12-18 months later. Patients reported at least moderate benefit finding in the majority of areas. More benefit finding was predicted by the presence of more advanced disease, Maori/Pacific Island ethnicity, lower baseline QOL, and the use of active coping strategies. These findings support the view that screening for QOL at diagnosis and facilitating the development of coping skills may lead to improved benefit finding and psychological adjustment in people with head and neck cancer. Identification of the factors that facilitate benefit finding may assist management of patients after treatment for HNC.

Systematic review on treatment of Zenker's diverticulum.

This study was designed to compare rates of failure, revision and morbidity from endoscopic and open approaches as treatment for pharyngeal pouch. Systematic review was conducted using MEDLINE and PubMed databases. Search terms treatment, Zenker's, hypopharyngeal, pharyngeal, diverticulum, and pouch. There were no randomised clinical trials. Therefore, cohort and comparative studies with at least 10 patients in each arm, a follow-up of a least 12 months and reporting on all patients were included. Seventy-one studies met inclusion criteria. Diverticulectomy with or without cricopharyngeal myotomy comprised 33 studies (1,990 patients), and endoscopic stapler diverticulotomy was in 22 studies (1,089 patients). Failure of open and endoscopic approaches was 4.2 and 18.4%, respectively, and corresponding complication rates were 11 and 7%. Within endoscopic techniques, failure rates were 18.9% for stapler diverticulotomy and 21.7% for laser diverticulotomy. Corresponding complication rates were 4.3 and 7.9%. Flexible endoscopy techniques have a higher failure (29%) and overall complication rate (14.3%). Most reported complications for transcervical techniques relate to the recurrent nerve (3.4%) and salivary fistula (3.7%) and for endoscopic group emphysema (3.0%) and mediastinitis (1.2%). Operation-related deaths were infrequent in both groups, but more frequent with open approach (0.9 vs. 0.4%). Open approaches have more success but more complications than endoscopic techniques. Taking in account overall complications and failure rates, open approaches and stapler diverticulotomy yield different patterns, but are arguably comparable. In younger patients open approach is preferred, as well in patients with unfavourable anatomic conditions for endoscopic exposure. Flexible endoscopic techniques provide a suitable option for patients who do not tolerate general anaesthesia.

Postoperative Systolic Blood Pressure as a risk factor for haematoma following thyroid surgery.

OBJECTIVES: To examine potential factors that may predict development of postoperative haematoma following thyroid surgery, with particular attention to postoperative systolic blood pressure. DESIGN: Retrospective, observational case-control study of patients undergoing thyroid surgery. SETTING: Secondary General Hospital. PARTICIPANTS: Patients attending Counties Manukau District Health Board (CMDHB) between 2002 and 2012. MAIN OUTCOME MEASURES: Post-operative Haematoma formation that required re-exploration of the wound. RESULTS: The overall rate of postoperative haematoma was 2.57% (16/621). Three patients bled immediately (i.e. after wound closure but while still on the operating table); 10 patients (1.6%) bled in the early postoperative period; and three others bled 24 h or more after surgery. The principal independent risk factor for postoperative haemorrhage that remained after multivariable regression was postoperative systolic blood pressure level. There was a 39% increase in risk of bleeding for every 10 points rise of highest blood pressure recordings in our patient population (OR 1.39; 95% CI = 1.09-1.8). CONCLUSIONS: This study identifies postoperative hypertension as significantly related to development of early postoperative haematoma. Cause for late post-thyroidectomy bleeding remains speculative.

Elective management of cervical and parotid lymph nodes in stage N0 cutaneous squamous cell carcinoma of the head and neck: a decision analysis.

There is uncertainty regarding the threshold for recommending elective regional nodal treatment in the management of stage N0 cutaneous squamous cell carcinoma of the head and neck (cSCCHN). Elective treatment in the form of nodal surgery or irradiation is associated with morbidity. However, patients managed with careful observation sometimes present with advanced disease which often require more extensive therapy or may be unsalvageable altogether. We used decision analysis to examine the tradeoffs and benefits of different management approaches in the stage N0 patient. A decision tree comprising the three different treatment strategies was built: surveillance, elective nodal dissection (END) and elective nodal irradiation (ENI). Probabilities of nodal recurrence and likelihood of successful salvage were obtained from the literature. A convenience sample of patients previously treated for metastatic and non-metastatic cSCCHN was interviewed using the standard gamble technique to determine utility for post-treatment health states. Sensitivity analysis was performed and the effect on the expected utility was examined. When the probability of occult metastasis was >19 %, ENI resulted in a higher expected utility than observation. When the probability of occult metastasis exceeds 25 %, END has a higher expected utility compared to observation. Given the current available evidence, a wait-and-see approach is justified in patients with a probability of occult metastases <19 %.

Postmortem investigation of mylohyoid hiatus and hernia: aetiological factors of plunging ranula.

The mylohyoid hiatus and hernia were discovered in the nineteenth century and were considered to explain the origin of the plunging ranula from the sublingual gland. This formed the rationale for sublingual sialadenectomy for the treatment of plunging ranula. However, a more recent, extensive histological investigation reported that hernias contained submandibular gland, which supported an origin of the plunging ranula from the submandibular gland and submandibular sialadenectomy for the treatment of plunging ranula. We therefore decided to investigate the occurrence and location of the hiatus and the histological nature of the hernia. Twenty-three adult cadavers were dissected in the submandibular region. The locations and dimensions of mylohyoid hiatuses were measured before taking biopsies of hernias. Hiatuses with associated hernias were found in ten cadavers: unilateral in six; and bilateral in four, in one of which there were three hiatuses. Sublingual gland was identified in nine hernias and fat without gland in six. This investigation supports clinical and experimental evidence that the plunging ranula originates from the sublingual gland and may enter the neck through the mylohyoid muscle. It confirms the rationale of sublingual sialadenectomy for the treatment of plunging ranula.

Amylase as a Diagnostic Tool for Plunging Ranula: Clinical Series and Description of the Technique.

OBJECTIVES: This study describes a technique of measurement for neck cyst amylase content and reviews the experience of a tertiary referral center for cases of suspected plunging ranula. METHODS: A retrospective study was performed at the Manukau Surgical Center in Auckland, New Zealand. Patients with a possible diagnosis of plunging ranula based on clinical presentation and diagnostic aspiration of the cyst contents were included. Demographic data, imaging and laboratory findings were collected, along with findings from surgery and histology. The technique for measuring the amylase of the aspirated cyst contents was also carefully recorded. RESULTS: The 37 cases of confirmed plunging ranula included in this study had a submandibular cystic swelling that was aspirated. Imaging features consistent with a plunging ranula were seen in 89% of the study group. All cases had detectable levels of amylase of ≥3 U/L in the ranula contents. There was large variability (range: 5-560 U/L) in the concentration of amylase, with 70% of the cases demonstrating an amylase concentration below 200 U/L. Aspirates were typically described as viscous (87.5%) and yellow or straw-colored. CONCLUSION: The combination of clinical presentation, imaging and the presence of amylase in the cyst contents is diagnostic for plunging ranula.

The Need for Studies on Oral Corticosteroids After Sialendoscopy for Obstructive Salivary Gland Disease: Systematic Review.

OBJECTIVES: This qualitative systematic review evaluates the evidence in support of the use of oral corticosteroids in patients undergoing sialendoscopy for the treatment of obstructive sialadenitis. DESIGN: Qualitative systematic review. METHODS: A literature search was conducted from January 1985 and September 2020. Inclusion criteria embraced peer-reviewed articles in which adult patients undergoing interventional sialendoscopy for obstructive salivary gland disease received oral corticosteroids. The results were initially screened based on title and abstract, and the remaining articles were reviewed for eligibility. RESULTS: About 218 papers were selected by title and abstract, 96 were selected for full-text review, and 9 met the inclusion criteria. Eight published reports were retrospective observational studies and 1 was a prospective comparative study. Overall, the heterogeneity of clinical data stood out in this systematic review. The pooled success rate in the studies was 873/979 (89%). Only 5 studies described a rationale for oral corticosteroid use as part of the post-operative management. In 4 studies, a prednisone total daily dose of 40 to 50 mg was used. One study clearly showed a lower recurrence rate in patients who received oral steroids for more than 7 days in addition to sialendoscopy for management of ductal stenoses. CONCLUSION: This systematic review showed that most centers that prescribe oral corticosteroids after sialendoscopy are unaware of the specific results with this treatment. For ductal stenoses, only 1 paper clearly showed the benefits of oral corticosteroids after sialendoscopy but more high-quality evidence is required in the form of a comparative study or randomized controlled trial, with appropriate long-term follow up.

Persisting variance in middle ear ventilation tube insertion in Auckland children: why ethnic disparity continues.

AIM: Insertion of ventilation tubes (VTs) is a common surgical treatment for recurrent and persistent otitis media, but surgical practice varies internationally. The current study explored variations in practice within New Zealand by examining VT insertion rates. The aim of the study was to determine time trends and current variations in VT insertion rates by ethnicity and district health board (DHB), with a focus on comparison of two DHBs in Auckland (Counties Manukau and Auckland DHB) to national average data. METHOD: Data for surgical procedures were analysed in the Atlas of Healthcare Variation domain, available via the Health Quality & Safety Commission website. Publicly funded events for New Zealand residents over a 10-year period (2009-2018) were examined for 0-4-year-olds. Individuals were assigned to their DHB of residence. VT rates for each DHB are presented per 1,000 population, with upper and lower confidence intervals calculated to the 95% level. RESULTS: There was a general decline in the rates of VT insertions for the 0-4-year-olds over the 2009-2018 decade. Analysis of the 2018 year showed variation by ethnicity and DHB. In CMDHB, ADHB and nationally, Asian and Pacific ethnic groups had the lowest rates of VT insertions compared to other ethnic groups. In CMDHB, the VT rates for Maori, Pacific and Asian children were less than half that of their respective groups in ADHB. The NZ European/Other ethnic group had the highest rates of VT insertions in CMDHB and nationally, but in ADHB, the rate for the NZ European/Other group was similar to that for Maori. CONCLUSION: These results are incongruent with evidence that Maori and Pacific children in New Zealand experience a greater burden of middle ear disease than NZ European children. The finding of persisting inequities in VT treatment for middle ear disease in 0-4-year-olds, with greatest impact on Pacific children, suggests that there may be a need for targeted middle ear screening for preschool children to detect pre-schoolers with ear disease, earlier than the 4-year-old B4 School Check.

Patient Outcomes After Unsuccessful Endoscopic Sialolith Extraction.

OBJECTIVE/HYPOTHESIS: To evaluate clinical outcomes following failed endoscopic extraction of salivary calculi and to assess any relation between clinical outcome and calculi location, number, size, and mobility. If sialendoscopy fails to extract the calculus, subsequent spontaneous passage of the calculus out of the ductoglandular system or secondary effects of sialendoscopy could mitigate the clinical impact of a residual sialolithiasis. STUDY DESIGN: Prospective observational study. METHODS: Prospective comparative study of endoscopic procedures for sialolithiasis performed in the Manukau Surgery Center, in Auckland, New Zealand, from 2010 to 2020. The recurrent symptoms and the variables related to the need for additional surgical intervention for salivary calculi were analyzed. RESULTS: Among the 465 sialendoscopy procedures, 154 (33.1%) were for obstructive sialolithiasis. Among these, there were 30 (19.4%) with unsuccessful stone extraction with re-operation for these failures performed in 14 of the 27 failed submandibular cases (52%) and 2 of the 3 parotids (66.7%). Location of calculi was a significant factor in predicting the need of further surgery. Patients with perihilar stones were 5 times more likely to have a failed procedure (P = .001). If the stone was intraglandular, the likelihood increased to 8.5 times (P = .005). The likelihood for a revision procedure increased almost 11 times if the stone was intraglandular (P = .004). Calculi size, mobility, multiple calculi, and presence of concurrent stenosis did not correlate with need for further surgery. CONCLUSIONS: A significant proportion of "failed" sialendoscopy did not require further intervention. Stone location was a significant factor in predicting a failed procedure and the need for re-intervention. Laryngoscope, 132:1029-1033, 2022.

The Manukau Salivary Symptoms Score for Assessing the Impact of Sialendoscopy in Recurrent Obstructive Sialadenitis.

OBJECTIVE: To examine the Manukau Salivary Symptom Score (MSSS) questionnaire as a validated tool to assess obstructive sialadenitis-specific symptoms to both indicate disease severity and assess the outcome after sialendoscopic procedures. STUDY DESIGN: A prospective observational study was performed from 2010 to 2019 comprising 164 patients undergoing sialendoscopy for nonneoplastic chronic obstructive salivary gland disease (COSGD). SETTING: Department of Otolaryngology-Head and Neck Surgery at the Manukau Surgical Centre, Auckland, New Zealand, between June 2010 and September 2019. METHODS: A prospective observational study was performed from 2010 to 2019 comprising 164 patients undergoing sialendoscopy for nonneoplastic COSGD. Patients completed the MSSS preoperatively and at postoperative follow-up. Statistical tests were used to compare pre- and postoperative answers. Cronbach's α was used to measure internal consistency. Finally, construct validity was determined by comparing the 5-question MSSS questionnaire to the preexisting 20-question Chronic Obstructive Sialadenitis Symptoms (COSS) questionnaire. RESULTS: Postoperatively, patients had significant improvements in pain, eating, talking, swelling, and quality of life (P < .001). The MSSS questionnaire was found to have high internal consistency (α = 0.938). Questions in the MSSS had a very strong positive correlation with 3 COSS questions, a strong positive correlation with 8, a moderate positive correlation with 4, and a weak positive correlation with 1. Four COSS questions were not considered relevant and were not included in the MSSS questionnaire. CONCLUSION: The MSSS questionnaire is a simple, validated questionnaire that is useful for assessing the impact of sialendoscopy in patients with COSGD.

Surgery for plunging ranula: the lesson not yet learned?

Our objective is to review our experience with treatment of plunging ranula and examine the efficacy of transoral excision of sublingual gland as the principal treatment. This study comprises a case series with chart review. A secondary otolaryngology service was used as the setting. Retrospective analysis of patient records was performed for a series of 95 consecutive cases of plunging ranula, which presented to our department between January 2001 and February 2010. Clinical presentation, investigations, diagnosis, treatment, complications and outcome were recorded. Literature search was performed using MEDLINE and OLD MEDLINE. 81 cases of plunging ranula were treated surgically by transoral excision of sublingual gland and evacuation of ranula contents. Mean operating time was 75.3 min. Twelve patients had undergone previous surgery elsewhere. One patient in our series had a recurrence, needing excision of sublingual gland remnant. Two patients had trauma to submandibular duct requiring excision of submandibular gland. Other complications were minor and transient. Review of literature revealed many diverse methods of treating ranula, with varying results. Our series makes a substantial contribution to the number of plunging ranulas reported in the world, and supports the use of transoral sublingual gland excision as first-line treatment of plunging ranula.

Do Postoperative Oral Corticosteroids Improve Results After Sialendoscopy for Ductal Stenosis?

OBJECTIVES: This study aims to review the effects of short- and long-term oral administration of postoperative corticosteroids in patients undergoing sialendoscopy for the treatment of obstructive sialadenitis due to ductal stenosis. STUDY DESIGN: Prospective comparative study. METHODS: A prospective observational study was conducted at Manukau Surgical Center in Auckland, New Zealand, where patients undergoing sialendoscopic surgery for recurrent obstructive sialadenitis due to ductal stenoses were reviewed. Univariable and multivariable analysis, and also logistic regression were performed to identify variables correlated with the likelihood of the need for revision surgery for persistent or recurrent symptoms. RESULTS: In this study, sialendoscopy was performed in 142 patients: 162 parotid glands (86.6%) and 25 submandibular glands (13.4%). Postoperative oral steroids were prescribed for 48 patients (34%); 19 (13%) were prescribed for less than 7 days and 29 (20%) for more than 7 days. In total, 33 patients (23.2%) required a revision sialendoscopy during follow-up due to recurrence of symptoms. Oral steroids prescribed for more than 7 days after a sialendoscopy reduced the likelihood of a revision procedure by 93% when compared with patients who did not receive this medication, and by 96% when compared with patients who received steroids for less than 7 days. CONCLUSION: The results showed that in our population oral administration of corticosteroids for more than 7 days after sialendoscopy for the treatment of recurrent obstructive sialadenitis due to ductal stenosis markedly reduced the need for later revision surgery. Routine use of corticosteroids for more than 7 days is recommended after sialendoscopy in patients with ductal stenosis. LEVEL OF EVIDENCE: II Laryngoscope, 131:E1503-E1509, 2021.

Bilateral Plunging Ranulas in South Auckland: Evidence for a Genetic Basis.

OBJECTIVES: We present a series of bilateral plunging ranula patients to examine the etiology, diagnosis, treatment, and prognosis of this condition. METHODS: A retrospective chart review was performed on all cases of plunging ranula treated at the Department of Otolaryngology-Head and Neck Surgery, Counties Manukau District Health Board, New Zealand, between 2001 and 2019. RESULTS: There were 17 patients with bilateral plunging ranulas from a total of 187 plunging ranula patients. Eight patients were of Pacific Island descent; six were Maori; and three were Asian. There were no European patients with bilateral plunging ranulas. There were three types of bilateral plunging ranula patients: 1) Metachronous plunging ranulas-Five patients presented with a unilateral plunging ranula with no evidence of a contralateral plunging ranula on initial imaging. Despite negative contralateral imaging findings, these patients developed a clinically evident contralateral plunging ranula 21 to 61 months later. 2) Synchronous plunging ranulas detected on imaging-Eight patients presented with a clinically evident unilateral plunging ranula but also had a contralateral plunging ranula detected on imaging. 3) Clinically evident synchronous plunging ranulas-Four patients presented with bilateral clinically evident plunging ranulas, which were also evident on imaging. Twelve patients underwent bilateral transoral sublingual gland excision and plunging ranula evacuation. CONCLUSION: All patients with a unilateral plunging ranula should be advised of the potential for developing contralateral disease, and this should be emphasized in patients of Pacific Island, Maori, and Asian descent.
