The objective of this study is to report the surgical outcome after middle fossa approach (MFA) plugging in patients suffering from a superior semi-circular canal dehiscence (SCD) syndrome. This is a retrospective case review. Tertiary referral center. Sixteen ears in 13 patients with a SCD syndrome suffering from severe and disabling vestibular symptoms with a bony dehiscence on CT scan >3 mm and decreased threshold of cervical vestibular evoked potentials (cVEMPs). We assessed preoperatively: clinical symptoms, hearing, cVEMPs threshold, size of dehiscence and videonystagmography (VNG) with caloric and 100 Hz vibratory tests. Postoperatively, we noted occurrences of neurosurgical complication, evolution of audiological and vestibular symptoms, and evaluation of cVEMP data. Tullio’s phenomenon was observed in 13 cases (81.3 %) and subjectively reported hearing loss in seven (43.7 %). All patients were so disabled that they had to stop working. No neurosurgical complications were observed in the postoperative course. In three cases (16.6 %), an ipsilateral and transitory immediate postoperative vestibular deficit associated with a sensorineural hearing loss (SNHL) was noted, which totally resolved with steroids and bed rest. All patients were relieved of audiological and vestibular symptoms and could return to normal activity with a mean follow-up of 31.1 months (range 3–95). No patient had residual SNHL. cVEMPs were performed in 14 ears postoperatively and were normalized in 12 (85.7 %). Two of the three patients operated on both sides kept some degree of unsteadiness and oscillopsia. MFA plugging of the superior semi-circular canal is an efficient and non-hearing deteriorating procedure.

p16 immunohistochemistry or HPV-PCR used alone appear to be insufficient. These results confirm the high prevalence of HPV-related oropharyngeal squamous cell carcinoma (OSCC) and the previously reported specific clinical and histological features, apart from age. It appears essential for future clinical trials to be stratified according to smoking and tumour HPV status, defined by means of reliable virological tests targeting E6/E7 mRNA and no longer a simple positive response to the p16 marker, as is frequently the case at the present time. New tests suitable for use in routine practice therefore need to be developed.

Patients undergoing percutaneous endoscopic gastrostomy (PEG) for pharyngoesophageal malignancies are subject to develop malignant seeding at the PEG stoma. Risk factors include an untreated or recurrent advanced stage squamous cell carcinoma at the time of the PEG procedure and an endoscopic pull-string gastrostomy. Diagnosis is frequently late because this rare complication is poorly known. Prognosis remains poor despite aggressive treatment. Physicians should be aware of this complication in the event of hypermetabolic uptake around or close to a PEG stoma in patients monitored for a pharyngoesophageal squamous cell carcinoma.
