Unilateral radiotherapy for well-lateralised oropharyngeal squamous cell carcinoma reduces treatment toxicity. This study evaluated whether routine contralateral tonsillectomy, performed to look for synchronous tonsillar malignancies, is justified.
Methods
A retrospective analysis was conducted of 81 patients treated with curative intent for oropharyngeal squamous cell carcinoma at a tertiary centre (2022–2024). All patients underwent positron emission tomography computed tomography. Contralateral tonsillectomy was performed in candidates for unilateral radiotherapy.
Results
Forty-two patients underwent contralateral tonsillectomy. Synchronous contralateral squamous cell carcinoma was identified in one patient (2.4 per cent) who required bilateral cervical chemoradiation because of extranodal extension found on neck dissection. Eleven patients (26 per cent) underwent staged procedures after a median interval of 21 days. Post-tonsillectomy haemorrhage requiring hospital re-admission occurred in one patient (2.4 per cent).
Conclusion
Routine contralateral tonsillectomy did not yield any findings that altered the laterality of treatment in any patient. This suggests that omitting contralateral tonsillectomy may complement de-escalation strategies.
Oncological and functional outcomes for T1-2 N0-1 (TNMv8) p16-positive oropharyngeal squamous cell carcinoma patients were analysed according to treatment: either transoral robotic surgery (TORS) (Surgery group – TORS and neck dissection ± adjuvant radiotherapy/chemoradiotherapy) or primary radiotherapy/chemoradiotherapy (Oncology group).
Methods
Single-centre retrospective observational study.
Results
The two-year disease-free survival rate was 88 per cent for the Oncology group (n = 42) and 95 per cent for the Surgery group (n = 44). The two-year overall survival rate was 98 per cent for the Oncology group and 100 per cent for the Surgery group. The functional swallowing outcome at two years post-treatment was similar in both groups. Subgroup analysis showed patients treated with surgery-only with no adjuvant treatment had the best functional outcome whilst patients treated with surgery and post-operative chemoradiotherapy had the worst functional outcome.
Conclusion
The overall oncological and functional outcomes at two years were similar in both groups. Patients treated with surgery-only had the best functional outcome without compromised oncological outcome.
Transoral robotic surgery is a minimally invasive technique used in the management of head and neck cancer, though post-operative odynophagia can be a significant issue. There is debate about the necessity of elective nasogastric tube placement during the peri-operative period. This study examines the proportion of patients requiring elective nasogastric tube placement and evaluates whether pre-operative factors predict the need for nasogastric tube feeding.
Methods
Data from patients who underwent transoral robotic surgery in Oxford were analysed to assess correlations between pre-operative factors and nasogastric tube feeding.
Results
Fifty-three patients undergoing transoral robotic surgery underwent elective nasogastric tube placement; 43 per cent required the nasogastric tube for feeding or medication. Multivariate analysis showed significant associations between nasogastric tube feeding and sex (p = 0.028), peri-neural invasion (p = 0.024), tumour size (p = 0.012) and concurrent neck dissection (p = 0.019).
Conclusion
Although nearly half of the patients benefited from elective nasogastric tube placement, the remainder did not. Benefits and risks of elective nasogastric tube placement should be carefully considered.
This study investigates the association between a history of previous cancers and the subsequent risk of developing head and neck cancer.
Method
A retrospective case–control design was employed, analysing 561 patient records from two National Health Service hospitals, with 273 patients diagnosed with head and neck cancer and 288 patients serving as controls.
Results
Statistical analysis revealed a significant association between prior cancer history, particularly squamous cell carcinoma (SCC), and increased risk of developing head and neck cancer (p < 0.05). Subtype analysis highlighted specific head and neck cancers, such as oropharyngeal and laryngeal cancers, as particularly associated with a history of SCC.
Conclusion
The findings suggest that previous cancer diagnoses, especially SCC, may predispose individuals to head and neck cancer, challenging the traditional focus on tobacco, alcohol and human papillomavirus as primary risk factors. These results underscore the need for incorporating prior cancer history into risk assessment protocols and surveillance strategies to improve early detection and patient outcomes.
Electrothermal bipolar vessel sealing devices are electrosurgical devices that seal tissues and blood vessels up to 7 mm in diameter. This paper discusses our experience using electrothermal bipolar vessel sealing devices in transoral head and neck surgery.
Methods
Electrothermal bipolar vessel sealing devices were used in five patients with lesions of varying size and type within the pharyngo-larynx. These were treated transorally by the otolaryngology department at the Royal Adelaide Hospital. Either the Medtronic LigaSure or BiZact devices were used for transoral resection, debulking or division of these lesions.
Results
Electrothermal bipolar vessel sealing devices were considered helpful in four out of the five cases. Success was dependent on suitable transoral access. A single unsuccessful case reflected the LigaSure jaw's inability to engage a large tumour effectively.
Conclusion
Electrothermal bipolar vessel sealing devices can be safely deployed transorally to treat lesions of the upper aero-digestive tract in selected patients. Further studies investigating additional indications would broaden applications of this approach.
Major haemorrhage is a rare complication after chemoradiotherapy for oropharyngeal squamous cell carcinoma. This is managed by interventional neuroradiology with endovascular embolisation of the bleeding vessel. This study aimed to describe radiological and clinical predictors of haemorrhage.
Methods
A retrospective case series was conducted of all patients with oropharyngeal squamous cell carcinomas who suffered a major haemorrhage requiring embolisation during or after treatment with chemoradiotherapy or radiotherapy alone, between 2013 and 2021, in Western Australia.
Results
This study included 14 patients, in two groups: haemorrhage group (n = 70) and tumour stage matched non-haemorrhage group (n = 7). Patients who haemorrhaged had a larger average transverse axial tumour size on pre-treatment computed tomography (38 mm vs 22 mm; p = 0.02) and tumours tended to involve the proximal aspect of the offending bleeding vessel. All patients who haemorrhaged developed deep cavitating or ulcerative tumour bed changes on post-treatment imaging (p < 0.0001).
Conclusion
Tumour bed ulceration or cavitation appears to be highly predictive of haemorrhage in this patient cohort.
The introduction of transoral robotic surgery into routine management of patients is complex. It involves organisational, logistical and clinical challenges. This study presents our experience of implementing such a programme and provides a blueprint for other centres willing to establish similar services.
Methods
Implementation of the robotic surgery programme focused on several key domains: training, logistics, governance, multidisciplinary team awareness, pre-operative imaging, anaesthesia, post-operative care, finance, patient selection and consent. Programme outcomes were evaluated by assessing operative outcomes of the first 117 procedures performed.
Results
The success of the transoral robotic surgery programme has been possible because of the scrupulous planning phase before the first procedure, and the time invested on team awareness and training.
Conclusion
Implementation of a new transoral robotic surgery service has led to: the development of a dedicated transoral robotic surgery patient care protocol, the performance of progressively more complex procedures, the inclusion of transoral robotic surgery training and the establishment of several research projects.
To compare the post-operative outcomes of transoral laser microsurgery, lateral pharyngotomy and transmandibular surgery in oropharyngeal cancer management.
Methods
Records of 162 patients treated with transmandibular surgery, transoral laser microsurgery or lateral pharyngotomy were reviewed. The transoral laser microsurgery cohort was matched with the lateral pharyngotomy and transmandibular surgery cohorts for tumour stage, tumour subsite and human papilloma virus status, and the intra- and post-operative outcomes were compared.
Results
Duration of surgery and hospital stay were significantly longer for transmandibular surgery. Tracheostomy and nasogastric feeding tube rates were similar, but time to decannulation and to oral feeding were longer in the transmandibular surgery group. Transmandibular surgery more frequently required flap reconstruction and had a greater complication rate. Negative margins were fewer in the lateral pharyngotomy group than in the transoral laser microsurgery and transmandibular surgery groups.
Conclusion
In comparison with transmandibular surgery, transoral laser microsurgery and lateral pharyngotomy were associated with fewer complications and faster functional recovery. Lateral pharyngotomy had a higher rate of positive margins than transoral laser microsurgery, with a consequently greater need for adjuvant therapy. Many patients are nonetheless unsuitable for transoral surgery. All these factors should be considered when deciding on oropharyngeal cancer surgical treatment.
To evaluate for the first time the prevalence of human papillomavirus in oropharyngeal squamous cell carcinoma in a Middle-Eastern population, and to determine associations between human papillomavirus profiles and clinicopathological characteristics.
Methods
A retrospective chart review was conducted of all patients treated for oropharyngeal squamous cell carcinoma at the Hotel Dieu de France University Hospital (Beirut, Lebanon) between January 2010 and 2016. Existing formalin-fixed paraffin-embedded tumour samples were analysed. Human papillomavirus DNA viral load and p16 expression were evaluated using polymerase chain reaction and immunohistochemistry respectively.
Results
Thirty patients (mean age of 60 years) were included. Twenty-seven per cent of patients were p16-positive/human papillomavirus DNA positive, 53 per cent were p16-negative/human papillomavirus DNA negative and 20 per cent were p16-positive/human papillomavirus DNA negative. Human papillomavirus 16 was the most frequent subtype (75 per cent). Smoking and alcohol consumption were significantly lower in the human papillomavirus positive group compared to the human papillomavirus negative group (p = 0.049 and 0.004, respectively).
Conclusion
Human papillomavirus rate was lower than reported rates in Western populations. Possible explanations include differences in social and cultural behaviours.
The incidence of oropharyngeal squamous cell carcinoma in the Western world is increasing, with the human papillomavirus epidemic implicated in this observed trend. The optimal treatment modality is yet undetermined regarding oncological outcomes.
Methods:
This study comprised 98 patients with oropharyngeal squamous cell carcinoma, treated with either primary transoral surgery with adjuvant therapy or primary chemoradiotherapy with curative intent, between 2008 and 2012. Clinicopathological characteristics including tumour–node–metastasis stage, human papillomavirus status, treatment modality, recurrence and overall survival were collated.
Results:
Five per cent of primary surgical patients had locoregional recurrences compared with 25 per cent of primary chemoradiotherapy patients. A lower rate of locoregional recurrence was observed in the human papillomavirus positive group.
Conclusion:
This paper reports higher rates of overall survival and local control for oropharyngeal squamous cell carcinoma treated with primary surgery compared with primary chemoradiotherapy. This reflects overall lower tumour stage and higher human papillomavirus status in this group.
This paper describes a case where a patient diagnosed with tongue base lymphoid hyperplasia was successfully treated with radiofrequency excision and interstitial radiofrequency-induced thermotherapy.
Case report:
A 53-year-old female presented with globus sensation, mild dysphagia, nocturnal breathing problems and ‘hot potato voice’ dysphonia. On flexible nasendoscopy, a visible tongue mass was seen to obstruct the posterior oropharynx. On magnetic resonance imaging scans, this mass looked suspicious of lymphoma, but on histology was confirmed to be benign reactive lymphoid hyperplasia. Sleep study findings indicated moderate obstructive sleep apnoea, with an apnoea–hypopnoea index of 18.1 events per hour. She was treated with radiofrequency-induced thermotherapy on three separate occasions.
Results:
A post-operative sleep study showed a dramatic improvement in the patient's apnoea–hypopnoea index (3.8 events per hour). This correlated well with the improvement in her sleep quality and reduction of snoring. Over the follow-up period, there has been sustained resolution of dyspnoea, with almost total restoration of voice quality.
Hairy polyps are rare congenital growths of the head and neck, mainly found in the nasopharynx and oropharynx. They are made up of two germ cell layers: the ectoderm and mesoderm.
Methods:
This paper reports a four-month-old who presented with breathing and feeding difficulties. Clinical examination was unremarkable, but a video taken by the patient's mother on her smartphone showed a mass protruding from the infant's mouth. Laryngoscopy performed in the operating theatre showed that the mass emanated from the left posterior tonsillar pillar.
Results:
The mass was removed transorally with no complications. Pathological examination showed a skin-covered pedunculated structure characteristic of a hairy polyp. The patient's follow up was unremarkable.
Conclusion:
To the best of our knowledge, this is the second English-language case report of a patient with a hairy polyp emanating from a posterior tonsillar pillar. This paper also highlights the growing usage of smartphones by patients to help physicians with their diagnosis and management.
Hairy polyps are rare, congenital malformations of the oropharynx and nasopharynx. To date, approximately 145 cases have been reported. However, the histogenesis of these lesions remains unclear.
Case report:
We report the case of a 2-day-old neonate presenting with a hairy polyp attached to the left palate, who re-presented aged 16 months with a discharging first branchial arch sinus.
Conclusion:
We propose this case as supporting evidence for the theory that hairy polyps are a malformation of the first branchial arch system.
We report an extremely rare case of the oropharyngeal form of tularaemia, causing a parapharyngeal abscess.
Case report:
A 48-year-old woman presented with fever, sore throat, breathing difficulty and a right-sided neck swelling. This mass had previously been treated with penicillin without response, and had already been surgically drained once in another hospital. On physical examination, the tonsils were exudative and hypertrophic and the pharynx was hyperaemic. A fluctuant, 4 × 4 cm mass was seen on endoscopic examination, originating from the left parapharyngeal area and protruding towards the pyriform sinus, and partly obstructing the airway. Microagglutination test antibody titres for Francisella tularensis were positive (1/1280). The patient healed completely after definitive drainage of the abscess and antimicrobial therapy for 14 days (streptomycin, 2 × 1 g intramuscularly).
Conclusion:
Tularaemia should be considered in the differential diagnosis of patients presenting with tonsillopharyngitis, cervical lymphadenitis and parapharyngeal abscess who do not respond to treatment with penicillin, even if they do not live in an endemic region.
Vallecular cyst is uncommon in infants. We treated a female infant with vallecular cyst, and curious magnetic resonance imaging findings. We also review 51 other cases of vallecular cyst in infants reported over the past 23 years.
Case report:
A three-month-old female infant presented with congenital inspiratory stridor and failure to thrive. Flexible laryngoscopy and ultrasonography revealed a cystic mass in the vallecula. Magnetic resonance imaging findings were initially curious because of artefacts from breathing and swallowing. Marsupialisation of the cyst was performed. Post-operatively, the patient was immediately free of symptoms.
Conclusion:
Magnetic resonance imaging presents various difficulties in infants, but has the best diagnostic effectiveness. We recommend the use of magnetic resonance imaging, flexible fibroscopy and ultrasonography to enable extensive examination of suspected vallecular cysts in infants. Marsupialisation has a recurrence rate of only one in 39 cases, and its safety and effectiveness are well balanced. Thus, prompt marsupialisation of vallecular cyst is the recommended surgical procedure.
This chapter discusses the case of a 32-year-old married man presented with a chief complaint of fondling his wife during sleep. He was an alert, healthy-looking, white male in no distress. The oropharynx was clear, without redundant tissue, and he had a normal neck circumference. A psychiatric interview was unremarkable, apart from some dysphoria over the long-standing, involuntary sleep-sex with his wife. The PSG study documented clinically significant obstructive sleep apnea (OSA), but no other sleep disorder or abnormal polysomnography (PSG) finding. A diagnosis was made of OSA with confusional arousals and sexsomnia, together with sleep-talking. According to the man's history, the sexsomnia began in close association with the onset of snoring, and both progressed in tandem over time. Sexsomnia may be triggered by OSA through confusional arousals with abnormal sexual behaviors during sleep. Nasal continuous positive airway pressure (CPAP) therapy controls both OSA and the associated sexsomnia.
Different strategies are available for the management of patients with early (i.e. tumour stage one or two) oral or oropharyngeal carcinoma and a clinically negative neck.
Material and methods:
In 2006, a questionnaire was sent to the eight head and neck cancer centres of the Dutch Head and Neck Oncology Cooperative Group. This questionnaire covered: the factors influencing the decision to perform an elective neck dissection; the neck staging procedure; and the types of neck dissection undertaken.
Results:
All eight questionnaires were returned completed. Respondents indicated that the site (n = 6), size (n = 7) and thickness (n = 6) of the primary tumour were important in decisions regarding elective neck dissection. Ultrasound-guided fine needle aspiration cytology was the most frequently used diagnostic technique (n = 7). Depending on the site and stage of the primary tumour presented, in the different cases 3–7 of the centres would perform an elective neck dissection. Selective neck dissections (i.e. levels I to III/IV) were more frequently performed than modified radical neck dissections.
Conclusion:
There was no uniformity regarding management of the clinically negative neck in patients with early stage oral and oropharyngeal carcinoma, within The Netherlands.
A styloid process (SP) cutter was developed and put into clinical use. The design of components of the ‘styloidectome’ was based on the principles of mechanics. The measurements of the individual parts were determined on the basis of morphological data of the oropharynx from 40 subjects undergoing tonsillectomy under general anaesthesia. Experiments showed that the instrument could be used to transect the SP and excise the amputated bones from the deep tissue space. We used the instrument for the resection of elongated SPs, via an oral approach, in seven in-patients (involving 10 SPs) under general anaesthesia and in two out-patients (involving three SPs) under local anaesthesia. The length of the resected SP ranged from 0.8 to 2.5 cm and the stump of the SP was smooth. The removal lasted only seconds and blood loss was minimal, without any complications. The styloidectome was reliable, easy to use and could be used for the resection of an elongated SP under general or local anaesthesia.
We present a case of malakoplakia presenting as a lesion in the oropharynx of an elderly smoker. In this case a clinical diagnosis of carcinoma of the pharynx was made, biopsy revealed the nature of the lesion and management was radically altered.
