Middle meatus nasal cytology compared to inferior turbinate cytology in non allergic rhinitis.

PURPOSE: Non allergic rhinitis (NAR) comprises different clinical definitions and phenotypes, including non inflammatory non allergic (NINAR) and cellular inflammatory forms. Nasal cytology, usually performed by scraping the inferior turbinate, is a non invasive, cheap and point-of-care tool to distinguish among the different NAR phenotypes, but still a relevant proportion of patients evaluated by nasal cytology receive a non precise definition of NAR phenotype. We hypothesize that collecting nasal cytology samples from middle meatus could increase the diagnostic accuracy. METHODS: Consecutive patients with chronic rhinitis without evidence of allergic sensitization were assessed for nasal cytology by means of scraping both the inferior turbinate and the middle meatus (lateral-inferior wall of the middle turbinate). RESULTS: 107 consecutive patients with NAR were enrolled in the study. According to inferior turbinate cytology, 42.1% were defined as affected by NINAR, 2.8% by bacterial rhinitis, 10.3% by non allergic rhinitis with eosinophils (NARES), 15.0% non allergic rhinitis with neutrophils (NARNE), 19.6% non allergic rhinitis with mast-cells (NARMA) and 10.3% non allergic rhinitis with eosinophils and mast-cells (NARESMA). Middle meatus cytology was in accordance with inferior turbinate cytology in only 37.6% of cases. Eosinophils and mast-cells were detectable more frequently in middle meatus samples (49.5% vs 19.6%, p < 0.01, 59.8% vs 29.9%, p < 0.01, respectively). 93.3% of NINAR patients received an inflammatory NAR phenotype at middle meatus cytology: 26.7% NARES, 24.4% NARNE, 31.1% NARMA and 11.1% NARESMA. CONCLUSION: Middle meatus cytology is more reliable than inferior turbinate cytology in phenotyping patients with NAR. Our study strengthen that nasal cytology should be implemented in clinical practice collecting samples at the middle meatus level.

Multistep and Multidisciplinary Management for Post-irradiated Carotid Blowout Syndrome in a Young Patient With Oropharyngeal Carcinoma: A Case Report.

BACKGROUND: Carotid blowout syndrome is a severe complication of head and neck cancer, associated with high mortality and morbidity. METHODS: We present a case of acute hemorrhage from the carotid artery of a 59-year-old man with a history of chemoradiotherapy for lingual base and oropharyngeal squamous cell carcinoma. The case was managed by a staged multidisciplinary approach of open arterial reconstruction, after initial endovascular hemorrhage control using stent graft. RESULTS: The patient was discharged to home with patent carotid artery, no sign of infection or bleeding, and autonomous ambulation. A CT/PET scan performed 6 months later confirmed healing and absence of tumor recurrence. CONCLUSIONS: A multidisciplinary approach involving vascular surgeons, ENT surgeons, plastic and maxillofacial surgeons is particularly appropriate in the management of carotid blowout syndrome to warrant a durable and effective repair of all the anatomical structures involved.

Cochlear function after type-1 tympanoplasty: endoscopic versus microscopic approach, a comparative study.

PURPOSE: To investigate and compare the effect of endoscopic and microscopic type 1 tympanoplasty on the cochlear function, to determine if they have a different impact on the inner ear function. METHODS: 72 ears treated by transcanal endoscopic type 1 tympanoplasty and 84 ears treated by microscopic type 1 tympanoplasty in 3 tertiary referral centers were enrolled in the study. Microscopic type 1 tympanoplasty were performed by transcanal or retroauricular approach. Only patients with mobile and intact ossicular chain were involved in the study. A retrospective chart review was performed. Main outcome measures were: (1) change in bone conduction thresholds at 250, 500, 1000, 2000, 4000 Hz; (2) change in bone conduction Pure Tone Audiometry; (3) correlation of audiometric outcomes with surgical technique, graft type and graft position. RESULTS: A mild postoperative bone conduction threshold shift was observed at 2000 Hz and 4000 Hz in both groups, without significant differences between the two groups. No statistically significant modifications in bone conduction were observed at any frequencies in patients operated by transcanal endoscopic approach compared with those who underwent transcanal or retroauricular microscopic type 1 tympanoplasty. Moreover, neither the placement nor the type of the graft seemed to influence the cochlear function preservation. CONCLUSIONS: The endoscopic and the microscopic approaches have a similar impact on the bone conduction threshold during type 1 tympanoplasty. In particular, the one-handed manipulation of the ossicular chain during the endoscopic technique did not show an increased risk of inner ear damage.

PRAME Expression in Mucosal Melanoma of the Head and Neck Region.

PRAME (PReferentially expressed Antigen in MElanoma), a cancer-testis antigen expressed in normal and neoplastic tissues with several functions, proved to be a useful diagnostic tool in the differential diagnosis between benign and malignant melanocytic lesions. The current study aims to perform PRAME stain on a retrospective case series of mucosal melanocytic tumors of the head and neck region to compare 3 different scores and evaluate the most reliable one in this diagnostic set. Immunohistochemical analysis for PRAME was performed in 54 benign and malignant mucosal melanocytic tumors of the head and neck region collected from 41 patients. The best-performing cutoff of PRAME-positive cells (nuclear stain) to differentiate benign and malignant mucosal melanocytic tumors of the head and neck region is that proposed by Raghavan and colleagues (<60%/≥60% of PRAME-positive cells), with 100% and 77.8% of benign lesions and malignant tumors respectively correctly identified. Applying this score, PRAME stain showed the best results (sensitivity, specificity, accuracy, and positive and negative predictive values) for the diagnosis of head and neck melanocytic tumors. However, a subset of PRAME-negative malignant tumors was identified, especially located in the palatal area (hard and soft palate). Finally, high PRAME expression (≥60%) was associated with specific sites (nasal cavity/nasal septum/turbinates nasopharynx, and the maxillary sinus), nodular histotype, and female sex.

Multifocal Fibrosing Thyroiditis: an Under-recognized Mimicker of Papillary Thyroid Carcinoma.

Multifocal fibrosing thyroiditis (MFT) is an enigmatic entity, characterized by multiple fibrotic scar-like lesions with a paucicellular fibrotic center surrounded by a cellular peripheral area with reactive-appearing follicular cell atypia and variable chronic inflammation. Although poorly recognized and likely underreported in surgical pathology, the entity is considered rare with only 65 cases to date-including the current one reported to expand on the preoperative findings of this under-recognized entity. The average age of the patients is 46.8 years (range 15-71 years), 94% are female, with female to male ratio of 15:1. Individual MFT lesions typically have a superficial location. The average number of fibrotic lesions is 15.4 (range 2-51 per MFT case). Their average size is 3.1 mm (range 0.4-15.1). MFT is a disorder of diseased thyroids, typically found postoperatively in glands removed for other reasons, such as chronic lymphocytic/Hashimoto thyroiditis (32.3%), follicular nodular disease (nodular hyperplasia) (30.1%), hyperthyroidism/diffuse hyperplasia (Graves disease) (9.2%). Intriguing is the association with papillary thyroid carcinoma-present in 38.5% of MFT cases, and particularly with sub-centimetric and multifocal papillary thyroid carcinoma, with which MFT can be confused. Cases where MFT is the only thyroid pathology (7.7%) can be preoperatively mistaken for papillary thyroid carcinoma, due to worrisome ultrasound (US) and cytologic features, both of which are here documented for the first time as a component of this article. Wider recognition of MFT and of its cytologic and ultrasound features at preoperative evaluation may reduce unnecessary thyroidectomies.

Management of Jugular Bulb Injury During Transcanal Endoscopic Tympanoplasty.

Variable internal jugular vein anatomy is not rare. A high jugular bulb (JB) is reported in 6 to 34% of cases and, it can be jeopardized during middle ear surgery, especially if dehiscent. Its injury represents a threatening complication of ear surgery. In recent years there has been an increasing trend in the use of endoscopic ear surgery for a wide range of otologic procedures, but being a one-hand technique, the management of bleeding still represents a challenge. The aim of this video, http://links.lww.com/MAO/B280 is to report the endoscopic surgical management of internal jugular vein hemorrhage during endoscopic type I tympanoplasty.

Does microscopic experience influence learning curve in endoscopic ear surgery? A multicentric study.

OBJECTIVE: The aim of the present study was to illustrate the learning curve of endoscopic type-1 tympanoplasty comparing experts in microscopic otology versus neophyte surgeons. METHODS: Eight ear surgeons, from tertiary referral centers, who had performed at least 30 endoscopic type 1 tympanoplasties were included in the study. Demographic data and medical records regarding the first 30 endoscopic type-1 tympanoplasties were retrospectively collected by each surgeon. A 14-questions survey focused on subjective aspects of the learning curve was administered. Surgeons were divided in two groups: one with previous experience in microscopic ear surgery (group 1) and one with no previous experience in ear surgery (group 2). The learning curve of endoscopic type 1 tympanoplasty was compared between the groups. RESULTS: Mean surgical time was 89.2 min in group 1 vs. 79.5 min in group 2 (p < 0.01). When divided in 5 surgeries-steps, the only significant difference was appreciated in the first 5 surgeries with a longer mean time in group 1 vs. group 2 (+28.4 min; p < 0.05). CONCLUSIONS: Surgeon's previous experience may influence the EES learning curve. Our results show that the first 5 surgical procedures are more challenging for surgeons experienced in microscopic surgery, subsequently the curve progression improves sharply and appears reversing the initial trend by the end of the 30 surgeries.

Supracricoid laryngectomies: long-term oncological and functional results.

CONCLUSIONS: Our results confirm that supracricoid laryngectomies (SL) are reliable techniques for glottosupraglottic tumors, even for selected T3 and T4 cases, if the indications are correct. These surgical techniques allow a good quality of life with the preservation of the larynx. OBJECTIVE: SL with cricohyoidoepiglottopexy (CHEP) and cricohyoidopexy (CHP) have been popular over the last 20 years for the treatment of the glottic and/or supraglottic squamous cell carcinoma due to demonstrated good oncological and functional results. We report our experience with these techniques, with special focus on long-term oncological and functional results. PATIENTS AND METHODS: We retrospectively reviewed 206 patients who had undergone SL with CHEP or CHP technique between 1987 and 1998 for glottosupraglottic squamous cell carcinoma in our department. The long-term results for 206 patients with T1-T4 laryngeal carcinomas treated with SL are reported: 90.8% CHEP and 9.2% CHP. The mean follow-up was 62 months. RESULTS: Oncological results: the 5-year actuarial disease-free survival was 85%; the 5-year determinate actuarial survival was 88.3%. Functional results: organ preservation rate was 97%. Phonation was assessed according to the GRBAS scale.
