Surgery for velopharyngeal insufficiency: The outcomes of the University Hospitals Leuven.

OBJECTIVES: We reviewed the outcomes of patients who underwent a velopharyngoplasty and subsequent speech therapy for velopharyngeal insufficiency (VPI) to determine possible prognostic variables. METHODS: During the period 2002-2010, 91 patients with VPI underwent a velopharyngoplasty (either the Honig velopharyngoplasty, the modified Honig velopharyngoplasty or the Hynes pharyngoplasty). Of these, 62 had complete data for long-term evaluation of speech outcome and analysis of variables potentially influencing this outcome. Speech outcome was assessed using five criteria that were evaluated pre- and postoperatively: hypernasality, nasal emission, facial grimacing, retro-articulation and glottal stops. The former two variables were transformed into a semi-objective nasality index (NI), the latter three variables were assembled to form a subjective articulation index (AI). Prognostic variables for outcome that were studied included age at velopharyngoplasty, associated 22q11.2 deletion syndrome, intervention type, primary or secondary surgery and pre-intervention speech therapy. RESULTS: Before surgery, based on the NI, 15 patients had mild VPI and 44 patients had moderate to severe VPI. Postoperatively at 12 months, 46 patients had a good speech outcome (normal or mild VPI), 13 patients had moderate VPI and no more severe VPI was observed. The overall success rate of 78% after one year increased to 90% in the long-term (median 27 months) with further speech therapy. Patients without the diagnosis of 22q11.2 deletion syndrome had better speech outcomes than patients with the syndrome. No statistically significant effect of the age at velopharyngoplasty on speech outcome was found. No cases of sleep apnea syndrome were reported. CONCLUSIONS: Our protocol of patient tailored surgical interventions and further postoperative speech therapy results in good speech outcomes, with no or only mild remaining VPI for the majority of patients. The correction of VPI is more difficult for the subgroup of patients with 22q11.2 deletion syndrome.

Transoral robotic surgery for parapharyngeal lesions: a case series of four benign tumours.

OBJECTIVES: The parapharyngeal space (PPS) is an anatomically complex space in the vicinity of vital structures. With the introduction of the daVinci robot in head and neck surgery, the surgical robotic system is now being used to gain direct access to the parapharyngeal space and to excise the tumors endoscopically. This study evaluates the outcomes of four patients with benign PPS tumors treated with a transoral robotic surgery approach in a single centre. MATERIAL AND METHODS: All patients with benign tumors of the PPS who underwent transoral resection (between January 2012 and June 2014) using the robot were included in this retrospective study. RESULTS: The study population comprised of two males and two females with a mean age of 52 (range 34-66 years). The parapharyngeal mass was successfully transorally removed in all cases. Overall, mean length of stay was 3.25 days with mean time to oral diet of one day. No intraoperative, perioperative or postoperative complications were encountered. The histological diagnosis was pleomorphic adenoma in two cases (50%). The other two cases were: schwannoma and angioma. There were no recurrences on radiological investigations during a mean follow-up of 14.5 months. MRI scan showed a stable residual fibrotic lesion in case of the angioma. The preoperative complaints of mucus in the throat, painless swelling of the soft palate or throat burden of all patients resolved after surgery. CONCLUSION: With the assistance of the surgical robotic system, benign tumors within the PPS can be excised safely without neck incisions. Further long-term evaluation is needed to define patient selection and the role of TORS for PPS neoplasms.

Myospherulosis as a complication of functional endoscopic sinus surgery: a double case report.

INTRODUCTION: Paraffinomas (also known as 'sclerosing lipogranulomas' or 'myospherulosis') are a widely acknowledged complication of cosmetic paraffin injections but they are rare following functional endoscopic sinus surgery. CASE PRESENTATIONS: Our first case features a 45-year-old woman presenting with a peri-ocular swelling two weeks after functional endoscopic sinus surgery. The procedure was complicated by a fractured lamina papyracea. A nasal packing with antibiotic ointment was left in situ. Initially, the inflammation was controlled successfully with corticosteroids but the swelling persists to this day. Our second case is a 45-year-old man who suffered from a recurrent swelling of the right eyelid after endoscopic sinus surgery. Multiple treatments with oral antibiotics and corticosteroids brought about no improvement. Debulking surgery was performed and a PDS film was placed between the peri-orbita and the bony orbital floor but the swelling recurred. The patient finally consulted a plastic surgeon as a last resort, but the reconstructive procedure only exacerbated the clinical picture. In both cases a biopsy was performed which established the foreign body reaction typical of a paraffinoma. At present, both patients still suffer from this condition. CONCLUSION: The complete resection of a paraffinoma is seldom possible because of diffuse infiltration and recurrence is very likely. We therefore conclude that paraffin-based ointments should not be used with nasal packing after sinus surgery, especially when there has been a lesion involving the orbital wall.
