Background: Inverted papillomas (IP) inserted in the frontal sinus and/or recess may be treated by using an endoscopic endonasal or an external approach. There are still few data available on this uncommon localization of IPs. Objective: To report our experience in the management of IP of the frontal drainage pathway, to describe a previously unreported specific complication of this surgery, and to discuss the optimal surgical strategy. Methods: A retrospective study of the patients at a tertiary care center between 2004 and 2014 who were operated on for an IP with an insertion in the frontal recess and/or the frontal sinus. Clinical charts were reviewed for demographics, clinical presentation, imaging findings, surgical treatment, and outcome. Results: Twenty-seven patients were included. Patients were operated on by using a purely endoscopic approach (Draf procedure; n = 14 [51.9%]) when the IP was inserted in the frontal recess and/or the frontal sinus infundibulum (with a nasoseptal-septoturbinal flap placed on the exposed bone in four patients), or by using a combined endoscopic and open approach (osteoplastic flap procedure; n = 13 [48.1%]) when the IP invaded the frontal sinus beyond the infundibulum. There were two recurrences (7.4%), with a mean follow-up of 40 months (range, 9‐123 months). During follow-up, single or multiple iatrogenic frontal mucoceles were observed in 10 patients (37%), with a mean delay of 60 months (range, 27‐89 months). These mucoceles occurred both after using endoscopic (n = 3) or combined (n = 7) approaches, and required a surgical treatment in eight patients. No postoperative mucocele was observed in the four patients who had had a septal flap. Conclusion: In our experience, an approach based on the localization of the IP insertion provided acceptable results in terms of the local control rate (92.6%). However, the significant rate of postoperative mucoceles indicated that specific strategies (such as local flaps) still need to be developed to avoid this iatrogenic complication.

To report on the presence of olfactory arachnoid dilatations (OAD), a previously undescribed radiologic feature of spontaneous cerebrospinal fluid (CSF) rhinorrhea originating from the cribriform plate of the ethmoid bone. The medical records of all patients treated between 2001 and 2011 at a tertiary care center for a spontaneous CSF rhinorrhea originating from the cribriform plate were retrospectively reviewed. The radiological work-up included high-resolution computed tomography and magnetic resonance imaging with at least the following sequences: T1, T2, and T2 with fast imaging employing steady state acquisition (FIESTA). Thirty cases were identified. The mean age at diagnosis was 49. Fourteen patients (47 %) had a body mass index (BMI) of 30 or more and 3 patients (10 %) had a BMI between 25 and 29.9. Five patients had a history of meningitis. The imaging work-up revealed a bone defect of the cribriform plate in 6 cases (20 %), associated to a typical meningocele in 14 cases (47 %). In ten patients (33 %), there was no defect of the cribriform plate, but ultrathin coronal T2-FIESTA sequences revealed an OAD, i.e. a dilatation of the arachnoid sheath of the olfactory fibers, in nine cases (30 %), or a 'pseudo-polyp' outlined by a thin layer of arachnoid (1 patient, 3 %). Preoperative imaging should be carefully analyzed for the presence of OAD or 'pseudo-polyp' in patients presenting with a CSF rhinorrhea without bony defect of the cribriform plate.

Background: Septic cavernous sinus thrombosis (SCST) is a rare but severe complication of acute bacterial sinusitis. Evaluations of advances in imaging techniques as well as in medical and surgical treatment are hampered by the lack of recent studies. Objective: We aim to report our experience in the management of SCST in patients with acute bacterial sphenoid sinusitis over the past 10 years and to discuss the initial work-up and treatment strategies. Methods: We performed a retrospective study of patients admitted for SCST related to acute sinusitis at a tertiary care center between 2003 and 2013. Clinical charts were reviewed for demographics, clinical presentations, imaging and microbiologic findings, medical and surgical treatments, and outcomes. Results: Seven patients were treated for SCST. Sphenoid sinus was involved in all cases. The most frequent presenting signs included headache (100%), cranial nerve impairment (86%), fever (71%), and orbital symptoms (71%). Diagnosis was confirmed by a cerebral contrast-enhanced CT scan in all cases. Four patients (57%) had an additional intracranial complication. The average time between clinical onset and diagnosis was 13.7 days. All patients were treated by high-dose i.v. antibiotics, anticoagulation therapy, and surgical endoscopic drainage of the infected sinuses. This treatment strategy resulted in a mortality rate of 0%, but four out of the seven patients developed transient or permanent neurologic deficits, including one with permanent unilateral visual loss. Conclusion: The combination of high-dose i.v. antibiotics, anticoagulation therapy, and endoscopic drainage of the infected paranasal sinus is an effective strategy for the treatment of SCST, but long-term sequelae remain frequent.

Background: The objectives of this study were first to show principles of the minimally invasive video-assisted thyroidectomy (MIVAT), based on a video highlighting critical steps, and second to discuss tips and pearls to assist surgical teams that would like to start using this technique. Methods: Based on a video, we described tips and pearls of a MIVAT. Results: MIVAT includes 5 main steps: (1) skin incision and identification of the common carotid artery, (2) dissection and ligation of the upper pedicle, (3) identification of the inferior laryngeal nerve and parathyroid glands, (4) isthmectomy and lobe extraction, and (5) closure. Discussion: Coordination between the surgeon and the 2 assistants is of paramount importance for the performance of MIVAT. Appropriate material is also required. The magnification and tissue contrast emphasizes the identification of the vessels, the superior and inferior laryngeal nerves, and parathyroid glands, on a large-view screen. [ABSTRACT FROM AUTHOR]

Pycnodysostosis is a rare osteopetrotic disorder. This report describes a case of a 3½-year-old boy with pycnodysostosis who presented with severe snoring. The snoring was the result of a pharyngeal narrowing due to a hypoplastic mandible. Surgery consisted of a bilateral rib graft, which allowed an enlargement of the pharynx by acting both on an anterior projection of the chin and a decrease of the glossoptosis. A significant reduction of the snoring and an excellent mouth aperture were obtained. This technique is ideal for such patients presenting a high risk of infection, nonunion, and secondary fracture.

Trismus is a frequent complication occurring after treatment of tumors of the pterygomaxillary fossa. Local flaps and full-thickness skin grafts fail to release it because they usually lead to scar contracture in previously irradiated tissues. We propose to release it with a thoracodorsal artery perforator flap, which is feasible in children like other perforator flaps. It is interesting because it is thinner than the anterolateral thigh flap and its scar may be less disgraceful and easier to hide. [ABSTRACT FROM AUTHOR]
