RESUMO
Microsurgical free flaps are common in head and neck reconstruction, and their techniques and outcomes have continuously improved during the past decades. However, there are variations in practice among surgeons between the use of closed-suction drainage systems and Penrose drains. The proponents of Penrose drains propose that the negative pressure generated by the closed-suction drainage system may harm the microvascular anastomosis. We know of no previous studies that have compared the two drains for microvascular free flap reconstruction, so our aim was to compare them in a single-centre, retrospective review of all patients who had microvascular free flap reconstruction of the head and neck region in our department between 1 November 2010 and 1 September 2017. During this period 84 patients had 87 free flap reconstructions in the head and neck, 43 of which had Penrose, and 44 closed-suction, drainage. We compared the number of complications between the groups including haematomas, seromas, wound infections, anastomostic thrombosis, anastomotic revision, and need for re-exploration. There were no significant differences between the groups, despite a trend toward fewer negative explorations in the closed-suction group. There were no differences in complications between suction and passive drainage systems after microvascular free flaps, which suggests that closed suction drainage could be safely used after free flap reconstruction in the head and neck.

INTRODUCTION: Early diagnosis of acute invasive fungal rhinosinusitis (AIFR) is crucial for patients prognosis and may reduce the extent of surgical debridement. Initial evaluation usually includes paranasal Computed Tomography (CT), with an emphasis on bony erosion which is considered a specific but insensitive radiologic sign. Most studies made no distinction between Aspergillus and Mucor species while addressing CT findings. In this study, we seek to evaluate whether bony erosion on paranasal CT is a significant and reliable finding in the initial evaluation of invasive paranasal mucormycosis. METHODS: A retrospective review of pre-operative non-contrast craniofacial CT scans of patients diagnosed with acute invasive fungal rhinosinusitis (AIFR) caused by Mucor species for the presence of bony erosion. RESULTS: A total of 13 patients (9 males, 4 females) were included. Twelve patients were immunosuppressed due to various hematological malignancies. Six patients underwent debridement due to gross intraoperative findings of bony fungal invasion, but only one patient had evidence of bony erosion on the pre operative paranasal CT. CONCLUSION: Bony erosion on paranasal CT is an exceptionally insensitive radiologic sign for establishing or rejecting the diagnosis of Mucor induced AIFR. The mainstay of confirming or rejecting the diagnosis of AIFR is by physical examination, endoscopy and oriented biopsy of suspicious mucosal lesions.

Merkel cell carcinoma is an uncommon and aggressive primary neuroendocrine skin malignancy which mostly affects the extremities and the head and neck region of elderly patients. Merkel cell carcinoma occurs with increased frequency in sun-exposed areas, in individuals exposed to arsenic and in immunosuppressed patients. Many patients with Merkel cell carcinoma present with other malignancies, mainly skin cancers. Characteristic features are frequent recurrences and regional and distant metastases. Mortality rates range from 20 to 65 per cent. The mainstay of treatment is surgery, with wide local excision, and adjuvant radiotherapy is usually administered. Merkel cell carcinoma of unknown primary site is rare, and the majority of the few cases described have not been from head and neck areas. We present a case of Merkel cell carcinoma of unknown primary site, with upper neck and distant metastases.

The superior mediastinum contains a considerable number of lymph nodes. Although occasionally involved in head and neck cancer, there are not many reports of mediastinal dissection in the practice of head and neck surgery. We present a group of seven patients with head and neck tumours that underwent mediastinal dissection in our department. Three patients are alive and free of disease six months to three years after the operation, two are alive with disease four and five years after the procedure, and two patients died peri-operatively. According to reviewed current literature, direct invasion of cancer of the head and neck to the mediastinum or mediastinal lymph node involvement is uncommon. Yet, mediastinal dissection provides the only chance for cure in selected cases.

The purpose of this study was to compare the findings of positron emission tomography (PET) with fused PET and computed tomography (CT) in patients with suspected locoregional and distant head and neck cancer and to evaluate the impact of those findings on clinical management. Studies of 25 patients were retrospectively evaluated. PET findings were classified as malignant, benign or equivocal. PET/CT findings were then similarly classified and the PET-only results were amended accordingly. Comparison of findings was done on lesion and patient levels. A total of 45 foci of increased 18F-fluorodeoxyglucose (FDG) uptake were noted in 18 patients. PET/CT imaging defined anatomic localization of 41/45 lesions and clarified 6/10 equivocal PET findings. Additional information was provided by PET/CT regarding 9/45 (20%) of the lesions. PET/CT significantly affected patient management in 3/25 patients (12%) by limiting the extent of disease in one and excluding viable disease in two others. The accuracy of PET/CT was 88%, the sensitivity 100% and the specificity was 77%. The negative predictive value was 100% in this combined group of patients with locoregional and distant head and neck cancer. PET/CT is highly contributory for initial staging and in the evaluation of patients with suspected recurrent SCC of the head and neck, in whom anatomic imaging is inconclusive due to the locoregional distortions rendered by surgery and radiotherapy.

Squamous cell carcinoma (SCC) is the most common cancer of the head and neck (HNC). Advanced HNC warrants extensive ablative and reconstructive procedures, significantly altering locoregional anatomy, while radiation treatment further adds to the distortion. Anatomic imaging is therefore often inconclusive in suspected recurrent HNC. Functional imaging with fluorodeoxyglucose-positron emission tomography (FDG-PET) has been reported contributory in the evaluation of patients with SCC. While most reports are from dedicated PET systems, full ring PET is of limited availability and gamma-PET may offer a suitable compromise. The therapeutic impact of gamma-PET in patients with suspected recurrent HNC was retrospectively evaluated. Seventeen patients were evaluated. All had undergone surgery for HNC, 16 also received radiotherapy. gamma-PET scans were compared to anatomic imaging, histopathology and clinical follow-up. The impact of the FDG-PET scan on patient management was then evaluated. Eleven positive findings were confirmed. Two false positives were due to radiation changes, a recognized pitfall. There were no false negatives. Overall accuracy of the 18F-FDG gamma-PET scans was 88% with considerable effect on patient management. Gamma-PET with FDG appears valuable in the evaluation of suspected recurrent HNC, and may provide a suitable alternative when dedicated PET is unavailable.

Mandibulotomy allows for wide exposure of deep oral cavity and oropharyngeal tumors and may be performed medial or lateral to the mental foramen. Medial mandibulotomy is divided into midline and paramidline. Midline mandibulotomy requires detachment of muscles which may lead to masticatory and swallowing problems and could potentially jeopardize the central incisors. Our study provides a basis for placement of bone cuts in mandibulotomy. The angles between the long axis of the two central incisors, the lateral incisor and canine bilaterally were measured in panoramic radiographs of 100 healthy patients. The distances between the roots were measured. The angle between the lateral incisor and the canine ranged from 1 degrees to 8 degrees compared to 1 degrees -4 degrees (P<0.001) between the central incisors. The distances between the lateral incisor and the canine were 1-6.2mm while the distances between the two central incisors ranged from 0.5 to 4.7mm (P<0.05). Although the measurements were taken from a younger group of patients compared to the usual age of presentation of oropharyngeal cancer, it shows that the paramidline mandibulotomy in which bony cuts are performed through a wider gap is the preferred approach.

A prospective analysis of olfaction was performed in 21 patients receiving cisplatin. A reduction in olfactory function was noted in only one patient. Hearing impairment was documented in nine patients, none of whom had impaired sense of smell. We conclude that cisplatin has no major deleterious effect on olfactory function at doses which cause hearing impairment.

Yellow Nail Syndrome (YNS) is characterized by a triad of ankle edema, pleural effusion and yellow nails. A close association was also found between YNS and rhinitis and sinusitis ranging from 25% to 83%. Although usually other symptoms precede rhinosinusitis, we describe three cases in which the onset of the upper respiratory tract manifestations predated nail changes and other characteristics of YNS. Our aim is to emphasize the importance of upper respiratory tract diseases in this uncommon syndrome.

OBJECTIVE: Our purpose was to evaluate the role of post-operative helical computed tomography (CT) and computerized reformations in patients after laryngo-tracheal segmental resection with anastomosis. METHODS: Helical CT and computerized reformations were obtained in 11 consecutive patients who underwent laryngo-tracheal resection with anastomosis for obstruction or stenosis caused by longstanding intubation or tracheostomy. Post-operative computer assisted cross-sectional area, coronal and sagittal diameter measurements at the level of maximal narrowing of the trachea were compared with clinical assessment in all patients. The additive value of various coronal and sagittal computerized reformations over axial images was subjectively evaluated by a consensus of a thoracic radiologist and a neuroradiologist who were blinded to clinical information. RESULTS: Various degrees of restriction in daily activities were reported by patients with cross-sectional area narrowing of more than 50%, by 4/6 patients with cross-sectional area of less than 90mm(2), by 4/5 and 4/6 patients with coronal or sagittal narrowing of more than 25% respectively, and by 4/5 patients with sagittal diameter of less than 12mm. All five patients with cross-sectional area stenosis of less than 50% assessed themselves as 'asymptomatic'. Sagittal multi-planar and volume rendering reformations clarified or added additional information over axial images in all six patients with significant cross-sectional area stenosis (>50%). Volume rendering scores were significantly higher than minimal intensity projection reformations (P=0.01). CONCLUSION: Our preliminary results suggest that CT-based cross-sectional area and diameter measurements of the trachea represent a clinically helpful tool for post-operative evaluation of patients with tracheoplasty. The need for post-operative endoscopy may be obviated in some cases.

Pilomatrixoma is a benign tumor of hair follicles that usually occurs as a single tumor and appears in the head and neck region, extremities, and trunk. The authors present a case of pilomatrixoma with multifocal localization. Simple excision of lesions is the recommended procedure, and recurrence usually is rare.

BACKGROUND: Hypothyroidism in the normal population age > 60 years is encountered in the range of 0.5-5% clinically, and 5-20% have subclinical hypofunction. Hypothyroidism is recognized as a common complication of treatment in patients with head and neck carcinoma (HNC) and is reported in up to 75% of patients who receive combined treatment. Surprisingly, base-line pretreatment measurements of thyroid function in large series of patients have not been reported. METHODS: Serum thyroid-stimulating hormone, free T4, and total T3 levels were recorded in 110 patients with nonthyroid HNC prior to treatment in a prospective, controlled study. RESULTS: The mean patient age (+/- standard deviation) was 65 years +/- 13.8 years, and 82% of patients had squamous cell carcinoma. A diagnosis of hypothyroidism already was established in 4.5% of patients, and subclinical hypothyroidism was discovered in an additional 6.4% of patients. Sixteen patients had other equivocal anomalies in thyroid function and were referred for further endocrine evaluation. No patients with formerly unrecognized clinical hypothyroidism were found. CONCLUSIONS: Hypothyroidism in patients with head and neck carcinoma in Israel corresponds with the reported incidence in the general population. Hypothyroidism after treatment for head and neck carcinoma stems from the effects of treatment. The need for pretreatment evaluation of thyroid function should be considered.

Cervical lymphadenectomy of level II encompasses lymph nodes associated with the upper internal jugular vein and the spinal accessory nerve (SAN). Removal of tissue superior to the SAN (submuscular recess-(SMR)) was recently shown to be unwarranted in selected cases of squamous-cell cancer. Thirty-five patients with non-squamous-cell cancer (SCC) of the head and neck treated with cervical lymphadenectomy were prospectively evaluated. Thirty-seven neck dissection specimens were histologically analysed for the number of lymph nodes involved with cancer. At the time of surgery, level II was separated into the supraspinal accessory nerve component (IIa) and the component anterior to the SAN (IIb). Neck dissections were most commonly performed for cancer of the thyroid gland (19) followed in frequency by the parotid gland (seven), skin: melanoma (five), basal-cell cancer (two), and other sites (four). Twenty-five neck dissections were modified-selective procedures and 12 were either radical or modified radical neck dissection. Twenty-nine necks were clinically N+ and eight N0. Histological staging was pathologically N+ in 32 neck dissection specimens. Level IIb contained an average of 12 nodes and the IIa component contained a mean of 5.0 nodes. Level II contained metastatic disease in 28 of 32 histologically node-positive specimens (87 per cent). Level IIa was involved with cancer in six cases (16 per cent), five of which were pre-operatively staged as clinically N+. All cases (100 per cent) with level IIa involvement had level IIb positive nodes. Three of the level IIa positive cases were cancer of the parotid gland comprising 43 per cent of this sub-group of patients. Incidence of involvement of SMR in non-SCC cases is not uncommon. The additional time required and morbidity associated with dissection of the supraspinal accessory nerve component of level II are probably justified when performing neck dissection in cancer of the thyroid gland. The SMR should be excised in cancer of the parotid gland. Large-scale prospective controlled studies with long-term follow-up periods are necessary to support resection of level IIb only.

OBJECTIVES: Acquired upper airway stenosis is usually associated with a complex of pathological conditions at the high tracheal and the subglottic levels. Reported reconstructive techniques include widening by incorporation of grafts, segmental resection, and anastomosis or combined procedures. The management of recurrent stenosis after reconstructive surgery is a major challenge and has rarely been discussed in the literature. The purposes of the present study are to compare the clinical course of primary versus revised reconstructive procedures and to analyze the effect of age, diabetes, chronic lung disease, grading of stenosis, extent of resection, and revised procedures on the operative rate of success. STUDY DESIGN: A cohort study in a tertiary referral medical center. METHODS: The clinical course of 23 consecutive patients undergoing laryngotracheal anastomosis was studied comparing a group of 13 primary with 10 revision procedures. Seventeen patients underwent cricotracheal and six patients thyrotracheal anastomoses. All patients but one were tracheotomized before the definitive reconstructive procedure. Suprahyoid release was routinely performed except for two cases, and only one patient required sternotomy. The Wilcoxon test was used to examine the relationship between preoperative clinical parameters and the postoperative success (i.e., airway patency). RESULTS: Twenty-two of 23 patients (95.6%) had successful decannulation. Four patients required a revision procedure because of repeat stenosis at the site of the anastomosis (2) or distal tracheal malacia (2). Residual airway stenosis of less than 50% was noted in six patients, although only three complained of dyspnea during daily-activity exertion. There was no associated mortality. Complications included subcutaneous emphysema (4), granulation tissue formation (3), pneumonia (2), cardiac arrhythmia (2), and one each of pneumomediastinum, neck hematoma, and urosepsis. Protracted aspirations were noted in one patient who had revision surgery. Age was the only parameter that correlated with postoperative airway patency (P <.07), whereas the presence of chronic obstructive lung disease and diabetes, grade of stenosis, type of surgery, and revision surgery were found to be insignificant. CONCLUSIONS: The clinical course of laryngotracheal anastomosis in primary and revised procedures was similar in our group of patients. The operation can be performed safely, with an expected high rate of success and acceptable morbidity.

OBJECTIVE: The purpose of this article is to present 14 cases of osteosarcoma of the jaw treated at our medical center from 1989 to 1998. These cases are discussed in the light of a comprehensive review of 774 cases reported in the English literature over the past 3 decades. Differences between osteosarcoma of the jaws and osteosarcoma of the long bones are examined. SUBJECTS AND METHODS: The patients ranged in age from 8 to 78 years, the mean age being 33 years. Each patient had a histopathologically established diagnosis of osteosarcoma of the jaw. Records were reviewed for epidemiologic data, treatment modalities, and survival. RESULTS: Of the 14 patients, 6 (42%) had tumors in the mandible and 8 (58%) had tumors in the maxilla. Of the mandibular tumors, 5 occurred in the body of the mandible; all maxillary tumors originated in the alveolar ridge and involved the maxillary sinus. The chief complaint was an intraoral or extraoral painless swelling. Histopathologic types included chondroblastic, osteoblastic, fibroblastic, and malignant fibrous histiocytoma-like. Pathologic grade was determined to be high (3 or 4) in 13 cases and low (1) in only 1 mandibular case. All patients underwent surgical resection and immediate reconstruction. Adjuvant therapy included postoperative radiation (5 patients), postoperative chemotherapy (2 patients), and preoperative chemotherapy and postoperative radiation (1 patient). CONCLUSIONS: The results of the present study support the literature indicating that osteosarcoma of the jaw differs from osteosarcoma of the long bones in its biological behavior even though they have the same histologic appearance. Because of differences in tumor characteristics, the introduction of chemotherapy did not dramatically alter the prognosis of osteosarcoma of the jaw. Early diagnosis and radical surgery are the keys to high survival rates.

BACKGROUND: Tumors in the parotid gland may affect salivary flow. The effects of tumor on glandular function and postoperative changes in both resected gland and contralateral gland were not formerly reported. We prospectively evaluated salivary flow rates and composition in patients undergoing parotidectomy preoperatively and postoperatively. METHOD: Stimulated parotid saliva from 17 patients undergoing parotidectomy was collected bilaterally preoperatively and postoperatively by using a parotid cup. Subjective complaints were recorded. Salivary flow rates, sodium, potassium, and amylase levels were evaluated. RESULTS: None of the patients complained of "dry mouth" before or after surgery. Analysis of the individual results revealed 3 patterns of preoperative and postoperative response, compatible with either a preoperative or postoperative compensatory mechanism in the contralateral gland. The postoperative decrease in flow rate corresponds with the amount of gland removed. Salivary electrolyte composition was unchanged. CONCLUSION: This study is the first to demonstrate the effects of parotid tumors and their surgery on salivary flow and a compensatory response and its different patterns in human parotid glands after their excision.

BACKGROUND: Reports of disability after neck dissection have been directed toward shoulder dysfunction and pain. We could find no report addressing the issue of pain localized to the actual operative site. We have conducted a combined prospective and retrospective study of pain in patients undergoing neck dissection. METHODS: Eighty-eight disease-free patients were evaluated in 3 groups for neck pain. One group was followed up prospectively for 1 to 8 months after surgery, and 2 retrospective groups were followed up for more than 2 years or for 6 months to 2 years. Pain was assessed by a body map and visual analog scale. RESULTS: None of 31 patients followed up for more than 2 years reported neck pain. Four of 27 patients followed up for 6 to 24 months had pain, with a mean visual analog scale score of 3.7. Seventy percent of the prospective group of 30 patients had pain during the first postoperative week, and only 1 patient had pain persisting for more than 2 months. Shoulder pain and disability after radical neck dissection were encountered in all groups, comparable with the incidence reported in the literature. No postoperative neuromas were found. CONCLUSIONS: Chronic pain localized to the operative site is an uncommon occurrence even after radical neck dissection. Chronic pain in the shoulder region may follow radical neck dissection, whereas modified neck dissection is usually a painless procedure.

Acquired benign tracheoesophageal fistula (TEF) is an infrequent complication of prolonged intubation and tracheostomy. Not infrequently, it is associated with severe circumferential malacia of the trachea and a need for concomitant correction of both. Controversy exists as to whether this should be performed in a single-stage or a 2-stage procedure. Four patients with acquired TEF underwent operation in a tertiary referral medical center between 1995 and 1997. The operations were performed through either an anterior (3) or a lateral (1) neck approach. Three patients underwent closure of the fistula with tracheal resection and anastomosis in a single stage and are doing well. One patient with complete subglottic stenosis underwent closure of the TEF and was planned for tracheal reconstruction in a second stage. This patient died in the early postoperative period. The complications included aspiration of blood leading to pneumonia (2), spontaneously resolving pneumomediastinum (1), subcutaneous emphysema (2), and cardiac arrhythmia ( 1). Residual fistula, noted in 1 patient, was treated conservatively and resolved spontaneously within several weeks. We conclude that acquired TEF is amenable to repair through a cervical approach. A single-stage correction of the TEF with reconstruction of the trachea is suitable and successful in most patients. Several stages seem justified when concurrent laryngotracheal reconstruction is needed.

OBJECTIVES: Prevertebral abscess formation is an uncommon occurrence following cervical spine fusion surgery. Abscesses may present early or in a delayed fashion and require surgical drainage and long-term antibiotic treatment. The issues of osteomyelitis and the need for plate removal remain unresolved. STUDY DESIGN: A case series of six tetraplegic patients admitted for rehabilitation to the Chaim Sheba Medical Center (Tel Hashomer, Israel) is presented. METHODS: Five patients were trauma patients; one patient underwent repeated procedures and irradiation for tumor of the cervical spine. All patients developed prevertebral abscesses after a mean period of 30 days from their fusion surgery. Computed tomography scan was used in all patients to establish the diagnosis and define the extent of the infective process. All patients underwent one or more drainage procedures. The plate was removed in two patients at 1 and 4 months. RESULTS: Infection completely resolved in four patient and was refractory in one patient with malignant tumor, and a chronic small fistula remained in one case. Staphylococcus aureus was the main infective organism, but mixed infections were the rule. Even for a protracted course of infection, no significant osteomyelitis was encountered. CONCLUSIONS: Abscess formation after instrumentation of the neck may be more common than formerly recognized. Despite the prolonged course of disease and treatment, osteomyelitis is not a major concern. There is no automatic indication for plate removal to control infection, although plating may be safely removed after 10 to 12 weeks if the neck is explored and the cervical spine is stable. A high index of suspicion is warranted, and early recognition and diagnosis, prompt surgical drainage under general anesthesia, and long-term antibiotic treatment are key for eradication of the infective process. Prophylactic antibiotics may be of value. Meticulous antisepsis and surgical technique should be maintained to reduce the incidence of these severe complications.

The brown tumour of hyperparathyroidism is a localized bone tumour and an uncommon manifestation of hyperparathyroidism. A 27-year-old woman presented with a mandibular 8 x 10 cm solid mass diagnosed as central giant cell granuloma. Chemical blood analysis revealed increased serum calcium levels of 12.46 mg/dL and the parathyroid hormone level was 124 pg/dL. The patient underwent surgery with removal of a parathyroid mass. Histologically, this parathyroid tissue was seen to be limited by a fibrous capsule with morphological features consistent with atypical parathyroid adenoma. The mandibular tumour has receded and the patient declined further procedures. This is the first case reported of brown tumour as the primary manifestation of an atypical parathyroid adenoma, a lesion that shares some features with parathyroid carcinoma without the unequivocal properties of malignancy.
