Ear, nose and throat manifestations of Churg-Strauss syndrome

Conclusion. Ear, nose and throat (ENT) involvement is common in Churg-Strauss syndrome (CSS), usually manifesting as allergic rhinitis and chronic rhinosinusitis with or without polyps. Otolaryngologists may play a pivotal role in making an early diagnosis of this disease. Objectives. CSS is a systemic vasculitic disorder that affects small to medium-sized blood vessels. Although the cause of CSS remains unknown, tissue damage seems more likely to be mediated by activated eosinophils. Patients affected by CSS frequently have ENT manifestations, which are often present at the time of disease onset and may represent relevant clues for the diagnosis. Thus, our objective was to present the ENT manifestations at the onset, at the diagnosis and at some point during the course of the disease in a series of patients with CSS collected at a single center. Materials and methods. Twenty-eight patients with CSS, as defined according to the 1990 American College of Rheumatology classification criteria, were identified. Twenty-one (75%) of these patients had ENT involvement. We evaluated the clinical course, laboratory data, histologic findings, treatment and outcomes. Results. Of the 21 patients, 13 (61.9%) had ENT involvement at asthma onset and 8 (38%) at diagnosis or during follow-up. The most common ENT manifestations were allergic rhinitis in 9 (42.8%) patients and nasal polyposis in 16 (76.1%). Three (14.2%) patients developed chronic rhinosinusitis without polyps, three (14.2%) had nasal crusting, one (4.7%) serous otitis media, one (4.7%) purulent otitis media, two (9.5%) progressive sensorineural hearing loss, and one (4.7%) unilateral facial palsy. Corticosteroid therapy associated with immunosuppressive drugs usually yielded improvement or stabilization.

Free flaps in elderly patients: Outcomes and complications in head and neck reconstruction after oncological resection

INTRODUCTION Free flaps represent the first reconstructive option for many head and neck defects. The increasing life expectancy of the population results in increasing numbers of ageing patients facing complex reconstructive surgery. In this study we evaluated our experience with free-flap transfers in older patients, analysing the post-operative reconstructive and systemic complications. MATERIALS AND METHODS Between 2000 and 2009, 360 patients underwent free flap reconstruction of defects resulting from the treatment of head and neck tumours at the Operative Unit of Maxillofacial Surgery, University - Hospital of Parma, Italy. Fifty-five patients (15.3%) were more than 75 years old at the time of treatment. RESULTS At the end of the follow-up successful free-flap transfer was achieved in 360 of the 373 flaps harvested (96.5%). The overall reconstructive complication rate was 31.4%, (31.8% in the younger group and 29.1% in the remaining patients). Medical complications were observed in 29.2% of cases (less than 75 years: 28.8%; more than 75 years: 30.9%). The ASA status was associated with a statistically significantly higher incidence of complications within patients less than 75 years old (p < 0.0001). DISCUSSION AND CONCLUSIONS The results of this study, in agreement with previous studies, provide evidence that free-tissue transfer may be performed in ageing patients with a high degree of technical success. The chronologic age cannot be considered an appropriate criterion in the reconstructive decision. On the contrary, a careful selection of the patients based on comorbidities and general conditions (ASA status) is of primary importance in reducing post-operative complications and to improving the results of surgery.

Early Surgical Laser-Assisted Management of Bisphosphonate-Related Osteonecrosis of the Jaws (BRONJ): A Retrospective Analysis of 101 Treated Sites with Long-Term Follow-Up

BACKGROUND DATA The management of bisphosphonate-related osteonecrosis of the jaws (BRONJ) is still controversial. OBJECTIVE The purpose of this study was to compare surgical and nonsurgical approaches to the treatment of BRONJ and the possible usefulness of Nd:YAG and Er:YAG lasers. METHODS One hundred and twenty-eight patients (33 males, 95 females; 52 with diagnosis of multiple myeloma, 53 with diagnosis of bone metastasis, and 23 with diagnosis of osteoporosis) affected by BRONJ were evaluated at the Unit of Oral Pathology and Medicine and Laser-Assisted Surgery of the University of Parma, Italy, between January 2004 and July 2009. Overall number of BRONJ sites was 151, and number of treated sites was 101. In order to assess the efficacy of different treatments, sites were subclassified as follows: Group 1 (G1): 12 sites treated with medical therapy; Group 2 (G2): 27 sites treated with medical therapy associated with low level laser therapy (LLLT); Group 3 (G3): 17 sites treated with a combination of medical and surgical therapy; Group 4 (G4): 45 sites treated with a combination of medical therapy, surgical (including laser-assisted) therapy, and LLLT. Outcome of treatment was assessed using the staging system proposed by Ruggiero et al. Transition from a higher stage to a lower one for at least 6 months was considered as clinical improvement and suggestive of a successful treatment. RESULTS Clinical improvement was achieved in 3 out of 12 (25%) BRONJ sites in G1. Sites if G2 with an improvement were 18 out of 27 (66%). Nine out 17 BRONJ sites (53%) in G3 had a transition to a lower stage after treatment. For sites in G4, a clinical improvement was recorded in 40 out of 45 cases (89%). CONCLUSIONS In our experience, the percentage of success obtained with a combined approach based on medical therapy, surgical (including laser-assisted) therapy, and LLLT (G4) is significantly higher than the percentage of improvement obtained in G1, G2, and G3.

Cross-facial nerve graft and masseteric nerve cooptation for one-stage facial reanimation: Principles, indications, and surgical procedure

The use of facial cross‐grafting in acquired recent unilateral facial palsy provides spontaneity and emotional activation. Masseteric nerve for facial animation has mainly been described for reinnervation of neuromuscular transplants, babysitter procedures, or direct facial nerve cooptation. The simultaneous use in a single procedure of cross‐facial nerve grafting and masseteric cooptation has not been described.

Rehabilitation with endosseous implants in fibula free-flap mandibular reconstruction: A case series of up to 10 years

PURPOSE To evaluate the clinical outcome and the aesthetic and functional results of implant rehabilitation of fibula free-flap reconstructed mandibles. MATERIALS AND METHODS The charts of patients who underwent mandibular reconstruction with fibula free flap and implant prosthodontic rehabilitation between 1998 and 2008 at the Operative Unit of Maxillofacial Surgery of Parma, Italy, were reviewed. In the study the estimated survival rates of implants placed in reconstructed mandibles we identified the prognostic factors and evaluated the functional outcomes. RESULTS Fourteen patients with a mean age of 50 years (range 15-63 years), were included in the study. A total of 62 implants were positioned. Complications occurred in 7 cases, an improvement in function and aesthetics was reported by the majority of patients. CONCLUSIONS A high survival rate for implants placed in fibula free-flap reconstructed mandibles was observed. Although different factors were believed to be associated with a poorer prognosis (radiotherapy, composite defects, etc.) no statistically significance was found, showing no absolute contraindications to implant placement.

Mandibular Resection and Reconstruction in the Management of Extensive Ameloblastoma

PURPOSE To present our experience with the management of 31 extensive mandibular ameloblastomas treated with segmental mandibulectomy, reconstruction with free fibula or iliac crest flap, and rehabilitation with immediate or delayed endosteal dental implants. PATIENTS AND METHODS The study sample comprised 31 patients with histologically confirmed mandibular ameloblastomas. Primary ameloblastomas were treated in 23 patients, and recurrent ameloblastomas affected 8 patients. Mandibular defect sizes ranged from 3.5 to 12.5 cm (mean, 5.6 cm). A free fibula osseous or osteocutaneous flap was used 17 times for reconstruction; in the remaining 14, a free iliac crest osseous or osteomuscular flap was chosen. Dental implants were positioned in 25 patients; implant procedures were performed simultaneously with reconstruction in 21 cases. RESULTS All flaps were transplanted successfully, and no major complication occurred postoperatively. Final histologic examinations showed 27 multicystic and 4 unicystic ameloblastomas. Free margins were achieved in all patients. The duration of follow-up was 18 to 120 months (mean, 53.6 months). No patient showed clinical or radiologic signs of recurrence. The dental implant success rate was 100%. CONCLUSIONS Segmental mandibular resection followed by immediate defect reconstruction with bone-containing free flaps with immediate dental implant placement should be considered as the treatment of choice for extensive mandibular ameloblastomas.

The role of surgery in children with head and neck rhabdomyosarcoma and Ewing's sarcoma

Rhabdomyosarcoma and Ewings sarcoma are relatively common malignant tumours in paediatric population. In the past, surgery was the mainstay of treatment and survival rates were poor. Afterwards, the development of multi-agent chemotherapy protocols during the past four decades resulted in a dramatic improvement in long-term survival. As a consequence, the significance of surgery has been the subject of critical discussion in the literature. Nowadays the standard treatment of rhabdomyosarcoma and Ewings sarcoma consists in a multimodal therapy involving chemotherapy, radiotherapy and surgery. Nevertheless, the role of surgery still remains controversial. In particular, the cure of head and neck localizations presents debatable aspects since defined criteria to establish the risks and the benefits of surgical treatment do not exist at this time. This article reviews the role of surgery in children with head and neck rhabdomyosarcoma and Ewings sarcoma. Indications, feasibility and timing criteria of surgical treatment have been reviewed and extracted from literature. Our case series is also presented.

Oncocytic carcinoma of parotid gland: a case report with clinical, immunohistochemical and ultrastructural features

BackgroundOncocytic carcinoma is an extremely rare neoplasm of the salivary glands. We report a case of oncocytic carcinoma arising in a parotid gland in a 66-year-old female.MethodAn excisional biopsy of the parotid tumor was performed. The specimen was submitted for histology and after fixation in formalin solution and inclusion in paraffin, 3–5 μm sections were stained with hematoxylin and eosin for conventional evaluation and Periodic acid Schiff stain. Immunohistochemical studies were performed using antibodies against mitochondrial antigen, keratin, S-100, alpha-actin, vimentin, alpha-1-antichymotrypsin as well as an ultrastructural analysis was performed.ResultsFrozen sections revealed an infiltrative growth pattern and the diagnosis of a malignant epithelial lesion was made. Permanent sections stained with haematoxylin and eosin revealed a neoplasm that had replaced a wide area of the parotid gland and had invaded subcutaneous adipose tissue. Perineural invasion was evident, but vascular invasion was not found. Neoplastic elements were large, round or polyhedral cells and were arranged in solid sheets, islands and cords. The cytoplasm was abundant, eosinophilic and finely granular. The nuclei were large and located centrally or peripherally. The nucleoli were distinct and large. Periodic acid Schiff stain demonstrated a granular cytoplasm. Immunohistochemistry demonstrated mithochondrial antigen, keratin, and chymotrypsin immunoreactivity in the neoplastic cells. Ultrastructural analysis revealed numerous mitochondria packed into the cytoplasm of the neoplastic cells. Thus, the final diagnosis was that of oncocytic carcinoma of parotid gland.ConclusionThis neoplasm shows clinical, microscopical, histological and ultrastructural features of oncocytic carcinoma and this must be considered in the differential diagnosis of other proliferations in the parotid gland with abundant granular cytoplasm and metastatic oncocytic carcinomas.

Clinical outcomes of rhabdomyosarcoma and Ewing's sarcoma of the head and neck in children.

OBJECTIVE To review our experience and critically evaluate treatment strategy and results in children with head and neck rhabdomyosarcoma and Ewings sarcoma. METHODS Retrospective charts review of children affected by non-orbital rhabdomyosarcoma or Ewings sarcoma of the head and neck who were treated at our institution from January 1996 to August 2009. RESULTS Seven consecutive children with head and neck rhabdomyosarcoma or Ewings sarcoma were identified. Four children had rhabdomyosarcoma, 3 children had Ewings sarcoma. Regions involved were: cheek, ethmoid and maxillary sinuses, nasopharynx, middle ear/mastoid and frontal bone. In one case, surgery was performed as primary treatment modality; the other children were treated firstly with chemotherapy. Three patients underwent surgical resection after chemotherapy, while 4 patients received radiotherapy. Five children are disease free after a median of 7.7 years from initial diagnosis. Two patients relapsed after 10 and 29 months from initial diagnosis respectively; despite the administration of additional therapy both children died of disease. CONCLUSION Treatment for rhabdomyosarcoma and Ewings sarcoma consists in a multimodal therapy involving chemotherapy, radiotherapy and surgery. The optimum use, timing and intensity of these three treatments are still matters of international debate. Chemotherapy in association with radiotherapy has proven capable to obtain local and distant control of disease. But when surgery is unfeasible or fails in radicality, local control is difficult without radiotherapy. Despite additional therapeutic efforts, prognosis of relapsing disease remains poor.

Involvement of level I neck lymph nodes and submandibular gland in laryngeal and/or hypopharyngeal squamous cell carcinoma.

OBJECTIVE To investigate the prevalence of level I neck lymph node metastases or submandibular nodal metastases in laryngeal and/or hypopharyngeal squamous cell carcinoma (SCC). PATIENTS AND METHODS One hundred fifty consecutive neck dissection specimens from 100 patients with laryngeal and hypopharyngeal SCC, who were treated at our institution between 1992 and 2002, were retrospectively reviewed. RESULTS The tumour stage was T1-T4, and the neck stage was N0-N3. Metastases were never found in level I (Ia + Ib) or in the submandibular gland. Metastases were concentrated within the jugular chain (levels II-IV in 92.2% of the N-positive necks). CONCLUSION Metastases of level I of the neck and the submandibular gland are extremely rare in cases of laryngeal and/or hypopharyngeal carcinoma. The risk of facial or hypoglossal nerve injury does not justify the dissection of level I and of the submandibular gland in this type of tumour.
