Vocal Outcome After CO2 Laser Cordectomy Performed on Patients Affected by Early Glottic Carcinoma

OBJECTIVE The objectives of this study were to assess the influence of the different types of laser cordectomy on vocal outcome and highlight the relationship between some perceptive, acoustic, and endoscopic evaluations. STUDY DESIGN Retrospective observational study. METHODS Thirteen patients, staged as having T1a tumor, underwent laser CO(2)cordectomy (1 patient type I and type II, 2 patients type II, 6 patients type III, and 4 patients type IV) between January and June 2010. Grade, roughness, breathiness, asthenia, and strain evaluation scale; voice handicap index-10 questionnaire; multidimensional computer analysis of voice and speech; maximum phonation time; and stroboscopic examination were performed 12 months after the surgery. Correlations between jitter% and R, shimmer% and R, noise-to-harmonic ratio (NHR) and G were studied. Patients were first divided into groups according to type of cordectomy performed and, later, according to stroboscopic findings. Wilcoxon test, Spearman index, and Kruskal-Wallis test, followed by post hoc analysis, were used. RESULTS No significant differences were found in type III and type IV cordectomy groups. Jitter% and R values showed a correlation as did shimmer% and B values, and NHR and G values in type III cordectomy group. Moreover, shimmer% and NHR values significantly increase in direct proportion to the severity of the endoscopic status. CONCLUSIONS Results indicate that the type of surgery performed, functional compensation, and outcome measures were related, although for some data, there were no statistical evidence. Individual compliance could strongly influence vocal outcome in these patients.

The role of PET/CT in the management of patients affected by head and neck tumors: a review of the literature

The management of head and neck tumor (HNSCC) has been changing over the years, especially due to the aid of imaging techniques that help physicians to attain a correct diagnosis. These techniques represent a valuable tool to help tailor treatment and during follow-up of patients affected by malignancies. The aim of this review is to summarize the results of the most recent and relevant studies about the use of PET imaging in HNSCCs. This review is divided into six chapters: (1) The role of PET/CT in the pre-treatment phase; (2) PET/CT and radiotherapy planning; (3) PET/CT in the post-treatment setting; (4) PET/CT and SUVmax for prediction of prognosis; (5) miscellanea on the utility of PET in specific HNSCCs; (6) non-FDG PET tracers used in HNSCC. Promising results have been obtained so far. Despite the encouraging outcomes, more investigations are needed to warrant the value of this technique, especially in the pre-treatment setting.

Evolution of soft palate surgery techniques for Obstructive Sleep Apnea patients: A comparative study for single level palatal surgeries

To compare the results of tissue preservation techniques of soft palate surgeries including expansion sphincter pharyngoplasty (ESP) and barbed reposition pharyngoplasty (BRP) for patients suffering from obstructive sleep apnoea (OSA) with the traditional uvulopalatopharyngoplasty (UPPP).

Palatal surgery in a transoral robotic setting (TORS): Preliminary results of a retrospective comparison between uvulopalatopharyngoplasty (UPPP), expansion sphincter pharyngoplasty (ESP) and barbed repositioning pharyngoplasty (BRP) [La chirurgia palatale all'interno di un setting robotico transorale (TORS): risultati preliminari di uno studio retrospettivo comparativo tra UPPP, ESP e BRP]

SUMMARY It has become increasingly clear in the past decade that surgical management of obstructive sleep apnoea hypopnoea syndrome (OSAHS) is most successfully managed with multilevel surgery. We evaluated the outcomes of multilevel interventions comparing three different palatal techniques added to TORS: uvulopalatopharyngoplasty (UPPP), a modified expansion sphincter pharyngoplasty (ESP), inspired by the Pang expansion sphincter pharyngoplasty technique and the latest barbed repositioning pharyngoplasty (BRP). Thirty patients were retrospectively evaluated. Ten patients underwent UPPP by Fairbanks, 10 BRP and 10 a modified ESP already described. All patients underwent TORS, tonsillectomy and septo-turbinoplasty. For all cases, the following data were retrieved and revaluated: preoperative and postoperative apnoea-hypopnoea index (AHI), preoperative and postoperative Epworth Sleepiness Scale (ESS), pain visual analogue scale (VAS; 0–10) for the first 5 days postoperatively, palatal operative time for each surgical technique, discharge date and complication types and rate. Both BRP and ESP resulted in better postoperative AHI values and higher surgical success rates in comparison with UPPP. On the other hand, BRP was not more effective than ESP. ESP surgery time was significantly higher than UPPP, while BRP was the quickest procedure. In summary, ESP and BRP seem to be more effective than UPPP in a multilevel surgical robotic setting. However, being quicker, easy to learn and with a low rate of complications, BRP is a safe, effective and promising option for treatment of OSAHS patients.

Mandibular advancement devices vs nasal-continuous positive airway pressure in the treatment of obstructive sleep apnoea. Systematic review and meta-analysis

Background Obstructive sleep apnoea (OSA) is a common disorder that may affect at least 2 to 4% of the adult population. Nasal-Continuous Positive Airway Pressure (N-CPAP) is today considered the gold standard for the treatment of OSA. The development of oral appliances (OAs) represents a new approach for the management of this pathology. The aim of this systematic review is to compare the efficacy of OAs and N-CPAP in the treatment of patients with mild to severe OSA. Material and Methods A PubMed-MEDLINE and Cochrane databases search of articles published between 1982 and 2016 comparing the effect of N-CPAP and OAs in OSA patients was conducted during July 2016. The studies were selected and stratified according to PRISMA and SORT criteria. The main outcome measure was post-treatment Apnoea-Hypopnoea Index (AHI) while secondary outcomes included post-treatment Epworth Score Scale (ESS) score and lowest Oxygen Saturation level. Results N-CPAP was significantly more effective in suppressing AHI than OA. Moreover, N- CPAP was significantly more effective in increasing post-treatment lowest Oxygen Saturation level than OA. However, no significant different in decreasing ESS values was found between the two treatments. Conclusions On the basis of evidence in this review it would appear appropriate to offer OA therapy to those who are unwilling or unable to persist with CPAP therapy. N-CPAP still must be considered the gold standard treatment for OSA and, therefore, OAs may be included in the list of alternative options. Key words:CPAP, obstructive sleep apnoea, oral appliances.

Trans-oral robotic surgery (TORS) for the treatment of lingual tonsillitis. When conventional therapies fail.

Lingual tonsillitis is an underestimated but serious health problem. This paper describes the feasibility and efficacy of the trans‐oral robotic surgical approach in cases of lingual tonsillitis.

La barbed reposition pharyngoplasty nella chirurgia multilivello robotica per il trattamento delle apnee ostruttive in sonno

SUMMARY The surgical treatment of obstructive sleep apnoea in patients who are non-compliant with continuous positive airway pressure therapy still represents a valid alternative. In recent years, the multilevel approach is becoming more diffuse in routine surgical practice, especially since the introduction of transoral robotic surgery. Barbed reposition pharyngoplasty in multilevel robotic surgery for OSA may represent a valid option to surgically approach the soft palate. Herein, we describe the technique and preliminary results of our experience.

Technetium-99m (99mTc)-labelled sulesomab in the management of malignant external otitis: is there any role?

We report two cases of malignant external otitis (MEO) evaluated with Technetium-99m(99mTc)-labelled sulesomab. Two patients affected by MEO are presented, together with a literature review. Both patients were studied with clinical examination, ear discharge culture, radiological imaging, blood exams, 99mTc Sulesomab, and treated with antibiotic therapy. 99mTc-Sulesomab would appear to be an useful tool for diagnosis and follow-up of MEO, highlighting the site and extension of the inflammatory process, and evaluating course and treatment efficacy. 99mTc-Sulesomab shows promise as a rapid, effective and safe imaging agent for treatment response evaluation and follow-up of patients with MEO. Further studies are warranted to validate the inclusion of 99mTc-Sulesomab scan in the imaging follow-up of patients with MEO.

Congenital Pyriform Sinus Fistula: Management of an Extra-Delayed and Atypical Case

Clinical presentations of pyriform sinus fistulas vary, and this sometimes leads to a delay in diagnosis and treatment. Recently, we experienced a case of recurrent cervical abscesses occurring after thyroidectomy in an adult affected by a bifidus pyriform sinus fistula. The diagnostic dilemma was related to the timing of events, with a single episode of acute suppurative thyroiditis having occurred 16 years before the onset of the more recent clinical scenario. An endoscopic approach allowed effective management of this clinical case.

Trans-Oral Robotic Tongue Reduction for OSA: Does Lingual Anatomy Influence the Surgical Outcome?

STUDY OBJECTIVES To evaluate both the influence of the volume of the excised base of tongue (BOT) on the surgical outcome after robotic tongue reduction in patients affected by obstructive sleep apnea (OSA) and the role of the lymphatic or muscular predominance within the removed tissue. METHODS Fifty-one patients with OSA were included in this study. All patients were treated with a robotic tongue base reduction. Data registered for the analysis were: age, sex, preoperative body mass index, preoperative and postoperative apnea-hypopnea index (AHI), delta AHI (preoperative AHI - postoperative AHI), total volume of the excised BOT, total thickness of excised BOT, isolated lymphatic thickness and soft tissue thickness (including muscular component) of the excised BOT, and lymphatic/soft tissue ratio (lymphatic thickness / soft tissue thickness). RESULTS A statistically significant reduction of AHI values was seen postoperatively, and a success rate of 74.5% was recorded. However, no significant correlations between delta AHI and tongue volume in cubic centimeters, lymphatic/soft tissue ratio, and total thickness were found. CONCLUSIONS These findings reinforce the general opinion that OSA is not only influenced by anatomic factors but other phenomena may play a fundamental role in its genesis. A deeper understanding of OSA pathogenesis is needed in order to tailor an individual treatment strategy that could lead to a more effective therapy.
