Oncological safety of the Hayes-Martin manoeuvre in neck dissections for node-positive oropharyngeal squamous cell carcinoma.

INTRODUCTION: The Hayes-Martin manoeuvre involves ligation of the posterior facial vein and superior reflection of the investing fascia below the mandible to preserve the marginal mandibular nerve. The peri-facial nodes thus remain undissected. We perform this manoeuvre routinely during modified radical neck dissection for metastatic oropharyngeal squamous cell cancer. Here, we review the oncological safety and marginal mandibular nerve preservation rates of this manoeuvre from 2004 to 2009. METHOD: Retrospective review of the head and neck oncology database (2004-2009) at Addenbrooke's Hospital, Cambridge, UK, a tertiary referral centre for head and neck oncology. RESULTS: Thirty-four patients underwent modified radical neck dissection for metastatic oropharyngeal squamous cell carcinoma. The primary tumour included the tonsil in 19 cases, base of tongue in 10 and posterior pharyngeal wall in 5. The neck nodal status was N1 in 4 cases, N(2a) in 11, N(2b) in 10, N(2c) in 4 and N(3) in 5. All patients had adjuvant radiotherapy. Median follow up was four years (range, two to five). No peri-facial nodal region recurrences were seen. Four patients had temporary marginal mandibular nerve weakness; beyond two months, no weakness was seen. CONCLUSION: In neck dissections for oropharyngeal squamous cell carcinoma, the marginal mandibular nerve and accompanying facial nodes can be safely preserved without oncological risk using the Hayes-Martin manoeuvre.

Safety of extracapsular dissection in benign superficial parotid lesions.

INTRODUCTION: The current practice for removal of clinically benign superficial parotid lesions is an appropriate superficial parotidectomy with a cuff of normal parotid tissue for complete pathological clearance. This technique requires the identification of the facial nerve at the main trunk and dissection of the segment of the facial nerve deep to the lesion. The reported major complications of this procedure include temporary or permanent facial nerve weakness, Frey's syndrome and salivary leaks. In order to avoid these complications, a local extracapsular dissection technique can be utilised in the management of small inferiorly located benign lesions of the parotid gland. METHODS: A retrospective case note review was performed for all parotidectomies between 2004 and 2009 in Addenbrooke's Hospital, Cambridge by the senior authors. RESULTS: A total of 172 cases were identified out which 46 underwent an extracapsular dissection. The average size of these lesions was 1.9 cm (0.9-2.4 cm) with all universally located inferior or posterior to the angle of the mandible. The pathologies were 14 pleomorphic adenomas, 24 Warthin's tumours, 6 lymphangiomas and 2 simple cysts. There were no post-operative facial nerve weaknesses, Frey's syndrome or salivary leaks within the extracapsular dissection group. The median follow-up of these patients were 4.6 years (2-6 years) with 6 patients lost to follow-up. No recurrences have been noted in the cohort at follow-up.

Positive findings on barium swallow in patients presenting with a "sensation of a lump in the throat".

Our objective is to evaluate the pickup rate of a significant pathology, on barium swallow, in patients who present to our clinic with a feeling of a lump in the throat (globus symptoms). Hospital--secondary referral centre. This is a retrospective study of 192 patients who had barium swallow in our department between August 2009 and August 2010. We revised 500 case notes to rule in 192 who presented with only a feeling of a lump in their throat. All patients with positive clinical findings, such as dysphagia, odynophagia, referred otalgia, hoarseness of voice, weight loss, neck swelling or vocal cord palsy, were ruled out. Eight patients were diagnosed on barium swallow as having significant pathology: five with diverticulae and three patients with oesophageal web. The percentage of significant pathology in our study is 4.17% (eight patients). Out of those eight cases, there was no malignant pathology identified on further panendoscopy. Our conclusion is that barium swallow adds very little to the diagnosis of Globus Pharyngeus, but it plays a role in the reassurance particularly from the patients' perspective.
