The aim of this communication was to introduce a novel combined image (magnetic resonance and computed tomography-guided and sialendoscopy-assisted transoral approach for the treatment of a parotid duct stenosis with megaduct.

A 46-year-old woman was referred to our department for recurrent infections of the right parotid gland following unsuccessful multiple transoral surgical approaches for a Stensen's duct stricture with megaduct. An image (magnetic resonance and computed tomography)-guided and sialendoscopy-assisted transoral sialodochoplasty was planned and performed.

No complications occurred. The patient was discharged 2 days after surgery. No more swelling or infections occurred. The patient is currently symptom-free after a follow up of 11 months.

Although imaging navigation means more technical effort and costs, this novel approach can be considered a viable surgical opportunity for distal and mid-third parotid duct stenosis with concomitant megaduct, particularly in cases of persistent inflammation or iatrogenic scars due to previous surgery.

This paper reports a rare case of a 61-year-old man with sialodochitis fibrinosa.

Clinical case report and review of current literature.

Sialodochitis fibrinosa is a diagnosis of exclusion and in many cases can be managed conservatively. Conservative management failed for this patient and he was managed successfully with staged bilateral total parotidectomy.

Sialodochitis fibrinosa should be considered as a differential diagnosis of painful bilateral facial swelling. While conservative management is successful for many patients, staged bilateral total parotidectomy may be necessary for full remission of symptoms; the timing of this is crucial to reduce the risk of facial nerve palsy.

Post-operative facial palsy is the most important potential complication of parotid surgery for benign lesions. The published prevalence of facial weakness is up to 57 per cent for temporary weakness and up to 7 per cent for permanent weakness. We aimed to identify potential risk factors for post-operative facial palsy.

One hundred and fifty patients who had undergone parotid surgery for benign disease were retrospectively reviewed. Tumour factors (size, location and histopathology), patient factors (age and sex) and operative factors (operation, surgeon grade, surgeon specialty and use of intra-operative facial nerve monitoring) were all analysed for significant associations with post-operative facial palsy.

The overall incidence of facial palsy was 26.7 per cent for temporary weakness and 2.6 per cent for permanent weakness. The associations between facial palsy and all the above factors were analysed using Pearson's chi-square test and found to be non-significant.

These outcomes compare favourably with the literature. No significant risk factors were identified, suggesting that atraumatic, meticulous surgical technique is still the most important factor affecting post-operative facial palsy.

First bite syndrome is a condition characterised by severe facial pain brought on by the first bite of each meal. This can severely affect the patient's ability to eat.

We present a 70-year-old woman for whom we performed a laser ablation of the left ear tympanic plexus, as treatment of first bite syndrome. A permeatal approach was used to raise a tympanomeatal flap. The tympanic plexus was identified on the promontory and a 4 mm2 area of the plexus was ablated using CO2 laser. The flap was repositioned and a dressing was placed with topical antibiotics.

At two-month follow up, there was full resolution of the patient's symptoms.

First bite syndrome carries a high morbidity; treatment options are variable, and often unsuccessful. We describe the first documented case of laser tympanic plexus ablation, with a very effective initial response. This procedure represents a useful therapeutic option for first bite syndrome.
