Osmo Pocket© vs VITOM®: comparison of surgical educational video recording means in head and neck reconstructive surgery.

PURPOSE: To highlight the needs for better intraoperative educational video recording in head and neck reconstructive surgery and to provide some information to standardize camera positioning in operative room. METHODS: The Authors compared the Osmo Pocket© and the VITOM® 0° Telescope, evaluating the faculty and trainees point of view through specific questionnaires. The study was performed during two Masterclasses on Head and Neck Reconstructive Surgery that took place in the Hospital Casa Sollievo della Sofferenza in 2018 e 2019. Camera positioning in the Operative Room was also assessed. RESULTS: In the faculty group, Osmo Pocket© was reported as frequently interfering with surgical intervention; the need for repositioning was reported more frequently in recording with VITOM®, that was evaluated as better in keeping a good "recording flow". In trainees' group, the perceived image quality with VITOM® was more appreciated, while Osmo Pocket© was considered superior in surgical field vision. Regarding the systems' positioning in the OR, in all the surgical procedures it was observed the need for the first operator and the trainees to have the HD monitor placed in front of them. Only during forearm flap harvesting the HD monitor was placed laterally to the first operator and the trainees. CONCLUSIONS: The Osmo Pocket© is a cheap solution and allows a stable and continuous vision of the operative field, without the needing for stop and repositioning. The Vitom®, despite its major costs and the needing for periodic repositioning, allows a better view of anatomical details with less discomfort for the surgeon. Moreover it's important a standardization of the video means positioning in the operative room to reduce the pre-operative times and to aid in the choice of the most useful method for educational video recording.

Functional outcomes in tongue reconstruction with myomucosal buccinator flaps.

OBJECTIVE: Buccal myomucosal local flaps in oral cavity reconstruction are a valid option for small-to-moderate defects. Nevertheless, few articles report about functional recovery. The purpose of the present analysis is to evaluate the impact of these flaps on function and quality of life. STUDY DESIGN: The study, retrospectively conducted on 36 patients who were surgically treated for tongue cancer between 2012 and 2018 at the Unit of Maxillo-Facial Surgery, Foundation IRCCS Casa Sollievo della Sofferenza, San Giovanni Rotondo (Italy), evaluates functional outcomes using the following 4 questionnaires: Performance Status Scale for Head and Neck Cancer Patients, M.D. Anderson Dysphagia Inventory, Speech Handicap Index, and European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Head and Neck Module. RESULTS: All patients are able to eat soft or more solid foods, and most of them eat quietly in public. Although 50% of cases reported a certain degree of dysphagia, it does not impact self-esteem and social relationships. Only 20% of patients have severe problems with speech. However, more than half of the cases (65%) report oral problems. CONCLUSIONS: The collected data confirm the suitability of the myomucosal cheek flaps for tongue reconstruction. Most patients report a good functional recovery and satisfactory quality of life even if none of them has a recovery comparable to the presurgical state.

Recurrent squamous cell carcinoma of the lower lip: salvage surgery outcome.

Squamous cell carcinoma (SCC) of the lip is one of the most commonly occurring oral cancers, mainly involving the lower lip. Despite a good prognosis in cases of early detection, survival rates drop dramatically in the presence of recurrence. While there are many studies in the literature regarding the management of primary tumours, the rate of recurrence in lower lip SCC is low and therefore there are few data and articles about them. We retrospectively reviewed patients affected by recurrent SCC of the lower lip treated surgically from 2011 to 2019 in a single centre. Data and results were compared with those in the literature. A total of 16 patients (mean [range] age: 78.1 [62-93] years) were eligible for inclusion. The disease-free survival rate at 2 and 5 years was 29.6% and the overall survival rate at 2 and 5 years was 14.4%. A significantly higher rate of failure and a worse prognosis was observed in patients with neck involvement. The prognosis of recurrent lower lip SCC is unfavourable with extremely low survival rates. This issue is probably linked to the oncological pathology but also to the advanced age of most patients, the presence of several comorbidities and, consequently, the high risk of perioperative mortality. For this reason, the analysis of data sets reported in the literature may help the surgeon in the management of recurrences and selection of patients.

Management of free flap failure in head and neck surgery.

Free flap surgery is overall considered the gold standard in head and neck reconstruction, with a success rate of 95%. The management of a total flap necrosis and which solution, between a pedicled or a second free flap, is safer for a salvage procedure is still controversial. Object of this study is to describe the authors' management of total free flap loss in head and neck reconstruction and compare the choices and results to those reported in the literature. From January 2012 to January 2016, 149 consecutive free flaps were performed at the Maxillo- Facial Operative Unit of the Hospital Casa Sollievo della Sofferenza in San Giovanni Rotondo (Italy) for reconstruction of head and neck defects. Of these, 6 flaps were lost due to a total necrosis. In 5 cases it was decided to harvest a second free flap, and in the remaining patient a temporalis muscle flap was used. All the free salvage flaps were successful, without complications and with a good aesthetic and functional recovery. Analysing the data obtained, and comparing them with those reported in the literature, it can be concluded that a second subsequent free flap can be considered an ideal and safe procedure in salvage surgery.

Intraoperative navigation in complex head and neck resections: indications and limits.

PURPOSE: The surgical removal of head and neck tumors often represents a highly complex surgery. The three-dimensionality and the anatomy of the head and neck area make sometimes difficult a correct intraoperative orientation and the obtaining of an adequate oncological safety. In the present pilot study, the authors propose a protocol of application of intraoperative navigation in the resection of head and neck tumors. The purpose is to develop a methodology that can be helpful to ensure oncologic free margins of resection and to facilitate the orientation of the specimen by pathologists. MATERIALS AND METHODS: A sample of 16 patients with head and neck tumors was selected, and they were differentiated into two groups: a "study group" treated with CT computer-assisted surgery and a "control group" surgically treated without the use of technology. The following data were analyzed: operative and pre-surgical planning times, issues related to the use of the technologies, respect of the planned landmarks, description and orientation of the surgical specimen and distance of the tumor from the margins of resection. RESULTS: In the "study group" were noticed a reduced rate of errors in the specimen orientation and an increased distance of the tumor from the margins of resection. Similar operative times were observed in both groups. CONCLUSIONS: Intraoperative navigation resulted to be a reliable method to improve oncological safety in a selected group of patients.

Endoscopic transnasal approach and intraoperative navigation for the treatment of isolated blowout fractures of the medial orbital wall.

The aim of this study is to describe the reduction of medial orbital wall fractures using a combination of two different techniques: the endoscopic reduction and the navigation aided reconstruction. The endoscopic approach avoids an external incision and allows the observation of the fracture site clearly. Navigation-aided reconstruction is essential to achieve precise and predictable results in orbital reconstruction. It consists in an ideal virtual reconstruction of the target area created using a mirroring tool, and superimposing and comparing the unaffected and the affected sides. This technique opens a broad spectrum of possible surgical approaches, especially in situations in which anatomical landmarks for precise positioning of bone fragments, or bone grafts, are missing. This study is the first to combine these two techniques. The study was carried out in seven patients who underwent endoscopic reduction of isolated blowout fractures of the medial orbital wall and navigation-aided reconstruction at the authors' institution. This pilot study clearly shows that a combination of the endoscopic reduction and the navigation-aided reconstruction provides functional results and great advantages in terms of anatomical preservation and postoperative morbidity.

Unresectable primary tumor of head and neck: does neck dissection combined with chemoradiotherapy improve survival?

A study regarding patients with primary and previously untreated advanced histologically proven squamous cell carcinoma of the head and neck was performed to compare two treatment modalities: neck dissection followed by chemoradiotherapy (Group I) versus chemoradiotherapy alone (Group II). Fifty-four patients were randomly chosen to receive Group I or II treatment. Our results demonstrate that Group I treatment has a higher and statistically significant disease-specific survival rate. We suggest that an association of neck dissection plus chemoradiotherapy can be useful in the event of unresectable advanced carcinomas.

[Rhinoscleroma with extramaxillary extension: report of a clinical case]. / Rhinoscleroma con estensione extramascellare: a proposito di un caso clinico.

Rhinoscleroma is a chronic, granulomatous infection most frequently affecting the respiratory tract mucosa. The disease is endemic in some geographic areas and is sporadic in Italy, where medio-facial granulomatoses must be differentiated from malignant naso-sinus neoplasms. The present work describes a case of rhino-sinus scleroma with extramaxillary extension, defining the most important clinical characteristics and the treatment performed.

Laryngopyocele: three new clinical cases and review of the literature.

Laryngopyocele is a fairly rare disease. It is a complication of laryngocele. Its clinical picture is often alarming; thus it needs fast differential diagnosis. Computed tomography allows early diagnosis. Surgical treatment permits a complete recovery. An association between laryngocele and carcinoma of the larynx has been reported by some authors. Three new cases of laryngopyocele are presented and discussed.

[Hormonal evaluation in the diagnosis of obesity associated with "primary empty sella"]. / Valutazione ormonale nella diagnosi di obesità associata a "primary empty sella".

To determine whether obesity associated with "primary empty sella" (PES) had a characteristic hormonal pattern, we evaluated the hormonal profile in 24 simple obese and 19 obese-PES women. The latter group showed a significant delta-GH and LH impaired levels as well as plasma beta-EP significantly higher. Hence, the beta-EP measurement could be used to predict the hormonal response in these women.
