Branchial cyst of the parapharyngeal space: Report of a case and surgical approach considerations
No full textIntroduction: Neoplasms arising within the parapharyngeal space are rare and represent approximately 0.5% of all head and neck tumors. The majority of these lesions consist of minor salivary gland tumors, tumors of the deep lobe of the parotid gland, and tumors of neurogenic origin (paragangliomi and schwannomi), while branchial cysts are extremely rare. Despite advances in radiographic images, surgical excision remains the definitive technique for the diagnosis of parapharyngeal space tumors. Results and discussion: The authors report a case of branchial cyst of the parapharyngeal space excised through a combined transcervical-transmandibular approach and discuss the several surgical techniques proposed to approach this type of tumors. © Springer-Verlag 2008
Drug induced sleep endoscopy and simultaneous polysomnography to predict the effectiveness of mandibular advancement device in obstructive sleep apnea treatment
No full textPurposes To evaluate whether mandibular advancement device therapy is recommended in patients affected by obstructive sleep apnea. Methods In order to predict oral appliances therapy response, drug induced sleep endoscopy with cardio-respiratory polygraphy and mandibular advancement device simulator was carried out. Patients in which upper airway obstruction was resolved on all levels and AHI was normalized (< 5/h), were referred for oral appliance therapy. At 5 months follow up, a cardio-respiratory polygraphy with MAD was performed. Results 36 patients who have evidence of resolution of UA collapse and AHI below 5 events per hour, were referred for MAD therapy. At follow up, the mean AHI decreased from 29.1 +/- 13.1 to 3.3/h +/- 1.9 (p < 0.001). All the patients were responders. Conclusion Combining the evaluation of drug induced sleep endoscopy and cardio-respiratory polygraphy data simultaneously during mandibular protrusion, has the potential to be a useful tool for prediction of MAD therapy response
Anterolateral thigh free flap for tracheal reconstruction after parastomal recurrence
No full textBackground. Stomal recurrence after total laryngectomy is 1 of the most serious issues in head and neck surgery, both because of the complexity of its management and because of its morbidity. Prior to the introduction of free-tissue transfer, mediastinal tracheostomy has been the standard reconstructive procedure with high rate of complications. The ideal reconstructive solution to these problems must provide well-vascularized soft tissues that can cover the defect after resection and also allow suturing of the tracheal remnant to skin edges without tension. Methods and Results. We describe a case of a 56-year-old man with stomal recurrence after total laryngectomy treated by the use of a tubed anterolateral thigh (ALT) flap to elongate the shortened trachea and simultaneously cover the cervical skin defect. Conclusions. The ALT can be accepted as an ideal free-flap choice for stomal recurrence, because it has maximal reconstructive capacity and produces minimal donor-site morbidity. © 2009 Wiley Periodicals, Inc
Silent sinus syndrome and maxillary sinus atelectasis in children
No full textObjective Silent sinus syndrome (SSS) and chronic maxillary atelectasis (CMA) are unusual conditions having subtle symptoms with a possible progressive evolution. They are particularly infrequent in the pediatric population. Our objective was to review our experience with pediatric patients having SSS or CMA, and to review all cases involving patients under 14 years of age reported in the literature. Methods A retrospective review of 6 patients diagnosed with SSS or CMA surgically treated from 2001 to 2014 was carried out. All cases reported in literature were reviewed. Results All patients underwent functional endoscopic sinus surgery with an improvement in symptoms after surgery. Diplopia disappeared in two patients who presented with it and enophthalmos improved in all five patients presenting with it. Only one patient out of four presenting with headache had a persistence of the symptoms which were, however, milder than they had been preoperatively. Endoscopic examination demonstrated a reventilated maxillary sinus in all cases. A radiological examination at follow-up was performed in 5 cases and demonstrated a reexpansion of the maxillary sinus as compared to the contralateral side in all patients except one. None of the patients required an orbital floor reconstruction. Eleven similar cases reported in the literature were analyzed and compared. Conclusion Endoscopic uncinectomy and middle meatal antrostomy should be the treatment of choice for these conditions in patients presenting with enophthalmos and/or hypoglobus and symptoms related to it. Orbital floor reconstruction should be performed as a delayed procedure only in selected cases. Chronic maxillary atelectasis or SSS should be considered as a possible cause of persistent headache of unknown origin in pediatric patients
Ultrasonographic assessment of tonsillar volume in children
No full textSir, we read with great interest the recent article by Asimakopoulos et Al. entitled “Ultrasonographic assessment of tonsillar volume in children”1. The study has been well planned and we would like to appreciate the effort made by the Authors to shed light on this topic. However there are few points regarding the methodology with which we have some reservations and would like to highlight these through your prestigious journal . First, the clinical utility of tonsillar volume as a predictor of OSAS severity has not been clearly demonstrated despite its widespread use. The etiologies of pediatric OSAS are diverse. Tonsil size is not the sole factor and this could explain why tonsillectomy is not 100 % curative2. Because the tonsils are larger relative to the airway size a better way to assess tonsil size clinically is to evaluate the tonsils within a more 3-dimensional/volumetric framework to capture the impact of the tonsils on the upper airway. Second, since in the paper by Asimakopoulos et Al indication for tonsillectomy was recurrent tonsillitis in about 70% of the patients, it could be hasty to conclude that “Preoperative ultrasound assessment of tonsillar anatomy and size may be an additional and suitable, objective method in the development of a risk stratification system in children with obstructive sleep apnoea undergoing tonsillar surgery”. Certainly, as supposed by the Authors, tonsillar ultrasound may have a role to assess for tonsillar asymmetry and potentially prevent patients from undergoing unnecessary diagnostic tonsillectomies. Finally, even if assessment of tonsils size is an effective screening tool for the clinical diagnosis of paediatric OSA , the true effect of tonsils volume on sleep disordered breathing requires further exploration. Particularly, in the case of a child who may be at higher risk for complications during surgery only a PSG may have real value in firmly establishing the risk of postoperative respiratory compromise potentially needing for ICU overnight observation3
Usefulness of three-dimensional computed tomographic anatomy in endoscopic frontal recess surgery
Full text linkThe endoscopic bidimensional vision offered by the endoscope during endoscopic sinus surgery involves difficulty in visualizing surgical field depth which makes it difficult to learn this surgical technique and makes it necessary for the endoscopic surgeon to mentally create a three-dimensional (3D) picture of the paranasal sinuses anatomy. In particular, frontal recess surgery requires good knowledge of its anatomic position, also since it is necessary to use angled endoscopes, which distort the view, and angular instruments which are difficult to use. Purpose of this project is to offer to the endoscopic surgeon a detailed 3D model of the nose and paranasal sinuses with particular attention to the frontal recess

Co-expression of Myoepithelial and Melanocytic Features in Carcinoma Ex Pleomorphic Adenoma
Full text linkThe presence of melanin pigment and melanocytic markers expression have been rarely reported in salivary gland tumors. Herein, two cases of carcinoma arising in pleomorphic adenoma of the parotid gland and showing diffuse expression of myoepithelial and melanocytic markers are described. The clinical-pathological clues useful in the differential diagnosis with melanoma are discussed. In addition, a review of the pertinent literature is also proposed, discussing the pathologic mechanisms potentially involved in this phenomenon
A case of severe obstructive sleep apnoea in Madelung's disease treated by lateral pharyngoplasty
No full textBackground: Madelung's disease is a rare disorder characterised by the presence of multiple, symmetric, non-capsulated fat masses in the face, neck and other areas of upper extremities. In some cases, severe clinical complications such as upper airway compression can occur. Case report: A 56-year-old man affected by Madelung's disease complained of snoring and severe daytime sleepiness. Polysomnography revealed severe obstructive sleep apnoea. An attempt to treat sleep apnoea by continuous positive airway pressure failed because of poor compliance. Functional expansion pharyngoplasty was carried out as an initial treatment. Marked improvement of neck movements and normalisation of somnographic parameters were observed at six months' follow up. Conclusion: Patients with Madelung's disease should be examined carefully for potential obstructive sleep apnoea. Although continuous positive airway pressure remains the treatment of choice, specific surgery can be used in those patients who cannot tolerate continuous positive airway pressure therapy
