Exclusive surgical treatment for vestibular schwannoma regrowth or recurrence: A meta-analysis of the literature
Full text linkVestibular schwannomas can be treated in different ways, but for symptomatic or growing tumors, the gold standard is surgical removal of the lesion. In order to preserve neurovascular structures, partial removal is often performed, leaving a residual that may grow in subsequent years. To date, there is no consensus with regard to surgical treatment of vestibular schwannoma residuals, and so this review focuses on this topic. A structured search was performed on PubMed searching for all articles discussing vestibular schwannoma residuals and recurrences. Only articles discussing surgical treatment were included, focusing on studies which also examined facial nerve outcomes. A total of 51 articles were eligible for review and these included 375 patients. Statistical analysis was performed by correlating the following parameters: patients' gender and age at first surgery, surgical approach adopted at first and subsequent surgeries, tumor and residual size, and extent of resection (gross total, near total, subtotal or others) at first and subsequent surgical procedures. Facial nerve function was also analyzed focusing on its performance when correlated with the different surgical approaches. The data were analyzed by linear regression but there were no correlations between any of the parameters chosen. There was a statistically significant difference between the first approach used (mainly the retrosigmoid route) compared with subsequent approaches (mainly the translabyrinthine route). In total, 8.5 % of patients needed further treatment due to residual regrowth. Facial nerve outcome was independent of the parameters chosen. Exclusive surgical treatment for vestibular schwannoma residuals had a very low failure rate in terms of requiring further treatment. The approach usually chosen for second surgery was the translabyrinthine technique, and this may be explained by the location of the residual, rather than its size. The choice of a particular surgical approach rather than another had no influence on facial nerve function. Complications rates are comparable to Gamma Knife Radiosurgery's as reported in the literature
Was Tiepolo’s wife affected by Graves' disease?
No full textTiepolo (1696–1770) was an Italian Rococo painter and printmaker, and is now considered to be one of the most important members of the 18th-century Venetian school. The muse that lent her face to Cleopatra and inspired many Tiepolo’s works was his beloved wife, Maria Cecilia Guardi. Because of her appearance, we cannot rule out that she suffered from Graves' disease, an autoimmune condition that is characterized by goiter, exophthalmos and restlessness

Role of the temporoparietal fascia free flap in salvage total laryngectomy
No full textThe procedure for salvage total laryngectomy (STL) is burdened by a high rate of postoperative complications as a result of delayed wound healing in previously irradiated tissue. Several observational studies have investigated the role of prophylactic vascularized flaps to aid pharyngeal closure after STL and prevent the development of PCF. The use of a temporoparietal fascia free flap (TFFF) as an overlay flap for STL has been described previously in two published studies and both sets of authors agreed that the most obvious benefit of the TFFF in STL is a reduced PCF rate with low site morbidity and good functional outcomes. The aim of this video is to illustrate the use of the temporoparietal fascia flap to provide an adjunctive reinforcement layer in the reconstruction of the pharynx
Modular Approach to Open Partial Horizontal Laryngectomy: Step-by-Step Anatomic Dissection
No full textOpen partial laryngectomies still play an important role in contemporary conservative management of laryngeal cancer. A comprehensive and systematic classification of open partial horizontal laryngectomies (OPHLs) was presented by the European Laryngological Society working committee in 2014. The aim of this video is to show the main surgical steps in OPHL using a cadaveric dissection and to explain the modular approach for removal of laryngeal tumors
Modular anatomic approach to oral tongue carcinoma: functional outcomes and quality of life
No full textObjectives. The purpose of this study is to present the long-term functional swallowing outcomes of various surgical approaches to oral tongue/floor of mouth squamous cell carcinoma (OTFOMSCC) according to a modular and compartment-based concept previously described elsewhere. Methods. A retrospective study was conducted on patients undergoing surgery for OTFOMSCC from January 2017 to April 2023 in the Department of Otorhinolaryngology at the Hospital of Bolzano. Functional swallowing outcomes and quality of life (QoL) were assessed through the administration of a scale and questionnaires between 6 months and 1 year postoperatively or after the end of adjuvant therapy, stratifying the results according to the surgical technique used. Results. A total of 92 patients with OTFOMSCC were enrolled: 44 patients underwent transoral anatomically guided surgery (TAGS) for early-stage tumours, and 48 underwent major surgery for advanced stages. Among the latter 48 patients: 35 underwent compartment tongue surgery (CTS), 3 underwent extended glossectomies (EG) Type A, 6 underwent EG Type B, and 4 underwent EG Type C. After TAGS, all patients resumed oral feeding for all consistencies. In the CTS group, only one patient faced challenges with pure liquids, yet all achieved the target of consuming a semisolid and semiliquid diet. EG exhibited a noticeable decline in performance from Type A to total glossectomy (Type C). Conclusions. Following an anatomically-guided approach to the resection of OTFOMSCC allows the surgery to be modulated on the structures involved by the tumour, thus achieving optimal oncological results, while maintaining the possibility to predict functional outcomes and postoperative QoL
Subcochlear canaliculus patterns in the pediatric and adult population: radiological findings and surgical implications
No full textIntroduction: The pneumatization of the different regions of the temporal bone is strictly related to the age and the degree of development of the mastoid and the middle ear. Petrous apex pneumatization is the last step of the development of the petrous bone system. The subcochlear canaliculus is an anatomical cavity, originating in the space between the fustis and the finiculus, and connecting the round window area to the petrous apex. The aim of the present article is analyzing the trend of development of the subcochlear canaliculus pneumatization, classified through CT scan examination, in different age subgroups. Materials and methods: We conducted a retrospective review of patients who underwent temporal bone CT scans between 2014 and 2019. Pediatric and adult patients were included and divided into different age subgroups. The subcochlear canaliculus was examined through coronal view scans at the level of the round window niche and classified into 3 different groups (A, B and C) according to the degree of pneumatization. Results: A total of 270 Petrous bone CT scans was analyzed. The percentage of type A subcochlear canaliculus was significantly higher in the pediatric population if compared to the adult population (p = 0.001326). As far as type B subcochlear canaliculus is concerned, the difference between children and adults was not statistically significant (p = 0.2378). On the other hand, type C subcochlear canaliculus was predominant in the adult population (p = 0.000256). Conclusions: There is a constant increase in pneumatization of the subcochlear canaliculus from 0 to 19 years and then a progressive decrease. This discovery has relevant surgical implications and has to be borne in mind in particular for cholesteatoma surgery and cochlear implantation surgery in the age groups in which the subcochlear canaliculus is highly pneumatized
Is endoscopic inspection necessary to detect residual disease in acoustic neuroma surgery?
Full text linkMain goals: To analyze how and when the endoscope is used in vestibular schwannoma surgery and identify the benefits of using endoscopy in this type of surgery. Background: It is currently unclear if there is any benefit from using an endoscope in vestibular schwannoma surgery so this retrospective analysis set out to study this. Methods: All the patients who underwent vestibular schwannoma surgery at our clinic were included for all the vestibular schwannoma approaches taken. We studied when endoscopy was used during surgery and the goal of using endoscopy. Several pre- and postoperative factors were assessed such as complications, facial function, and hearing function in the case of techniques that allow hearing preservation. Results: From January 2015 to September 2018, 280 patients underwent lateral skull base surgery. Of these, 112 were included in this study. The endoscope was used in all 112 patients, and in eight cases it was possible to identify residual disease using the endoscope to check the surgical field, and then to remove the disease under endoscopic view. Moreover, in two other cases, the endoscope was used to resolve a vasculoneural conflict between the anterior inferior cerebellar artery (AICA) loop and facial nerve in one case, and for deafferentation of the superior and inferior vestibular nerves in the second case. No major intraoperative complications occurred in our series. There was no statistically significant difference in postoperative facial nerve function between patients in whom the endoscope was used as a diagnostic tool and patients in whom it was used as an operative tool (p = 0.3152). Conclusions: The endoscope may be useful, especially in surgical techniques where there is poor control of the internal auditory canal (IAC). An endoscopic support technique is strongly recommended to avoid residual disease, particularly in retrosigmoid and retrolabyrinthine approaches. Moreover, the recent introduction of the transcanal transpromontorial approach allows the endoscope to be used during all the procedures in patients affected by a vestibular schwannoma limited to the IAC or to support surgical procedures during an enlarged microscopic approach
Role of endoscopy in lateral skull base approaches to the petrous apex
Full text linkObjective: The aim of this article is to study the role and advantages of combined microscopic/endoscopic procedures or exclusive endoscopic approaches in the treatment of petrous apex pathologies. Methods: The study was designed as a retrospective case series analysis. We included patients affected by pathologies of the petrous apex, who underwent microscopic/endoscopic-assisted or exclusive endoscopic procedures. Patient and pathology characteristics and surgical data (focusing on the involvement of the internal carotid artery (ICA) and facial nerve by the disease) were collected. Residual disease, detected through the endoscopic check, and the feasibility of endoscopic residual tumor removal were also evaluated. Finally, facial nerve and hearing functions were assessed pre- and postoperatively. Results: The records of 75 patients undergoing lateral skull base surgery for petrous apex lesions, from May 2009 to March 2019, were collected. In 17 out of 75 patients, an exclusive endoscopic procedure was possible. The remaining 58 patients underwent a combined microscopic/endoscopic approach. In 15 cases, residual disease was found and removed endoscopically at the end of the microscopic procedure; in eight cases, the residual disease was medial and/or inferior to the horizontal segment of the ICA, while in two cases, it was located in the fundus of the internal auditory canal. In five cases, it involved the labyrinthine segment of the facial nerve. Conclusion: Petrous apex surgery remains a traditional microscopic-based surgery, but the recent advent of endoscopic surgery has permitted an improvement in radicality minimizing the manipulation of neurovascular structures
