The Modification of Rotation - Advancement Flap Made in 1950.

The early techniques of cleft lip repair involved the straight-line technique, the triangular flap technique or some kind of geometric line (triangular, quadrangular closure). A turning point in cleft lip surgery was in 1955 when doctor. Millard presented his method: the rotation-advancement technique or flap, at the First International Congress of Plastic Surgery in Stockholm. Today, the technique, with or without some modifications, is used by more than 85% of cleft surgeons around the world. We are presenting a patient with complete unilateral cleft lip and palate who underwent surgery sixty-five years ago. The scar on his lip was similar to rotation advancement line. Cheiloplasty was performed by Professor Sercer in 1950, five years before Millard's publication. Professor Ante Sercer was an internationally recognized Croatian scholar in the area of ear, nose and throat diseases. He also gave a significant contribution to surgical management of velopharyngeal insufficiency and plastic surgery of the nose and ear.

[INFLUENCE OF NECK DISSECTION ON THE CORRESPONDING MOTOR AND SENSORY NERVES]. / UTJECAJ DISEKCIJE VRATA NA ODGOVARAJUCE MOTORICKE I OSJETNE ZIVCE.

OBJECTIVE: Radical neck dissection (RND), utilized for treatment of lymph node metastases in patients with head and neck cancers, can result in clinically significant functional disturbance secondary to the corresponding nerve damage. However, there is only limited data relative to post-operative analysis of impact of RND on the cranial and cervical nerves after neck dissection especially regarding the technique used such as electroknife or scalpel. STUDY DESIGN: 48 patients (42 men and 6 women) with intraoral cancer were enrolled. A total of 55 dissections were performed, including 7 patients who received bilateral dissections. Analysis of motor and sensory nerves was conducted seven days and three months later with regard whether electroknife or scalpel was used. RESULTS: The most frequent post-operative loss of motor function was seen in accessory and hypoglossal nerves; within sensory nerves the lingual nerve was most frequently dysfunctional. Permanent diaphragm dysfunction was seen in 15% of investigated patients. CONCLUSION: We might conclude that routine evaluation of sensoneural and motor nerve function of all potentially damaged nerves should be performed after RND, especially regarding diaphragm paralysis. There were no differences in postoperative nerve function of the examined nerves with regard to the technique used (electroknife/scalpel).

Evaluation of sentinel node biopsy in oral carcinomas.

It is still a matter of debate whether sentinel node biopsy might replace neck dissection in patients with clinically negative neck lymph nodes who suffer from oral squamous cell carcinoma. In 30 patients (26 male, 4 female, average age 59.4 years) with oral squamous cell carcinoma we performed ultrasound guided punction of the lymph nodes which were lymphoscintigraphically seen together with histopatological analysis of the dissected node. Sentinel lymph node was seen in 93% cases. By use of lymphoscintigraphy sentinel node was verified in 23 patients. Ultrasound guided punction showed presence of regional disease in 10% of cases, whereas sentinel biopsy revealed 23 of the converted necks. Histopathological findings were positive in 33% of our patients. The results of this study revealed that sentinel biopsy did not reveal 27% of the patients with positive neck histopathology. In conclusion, sentinel node biopsy should be performed in selective cases as in some localizations it is easier to perform neck dissection in comparison to the sentinel node biopsy.

Sclerosing polycystic adenosis of parotid gland: a unique report of two cases occurring in two sisters.

Sclerosing polycystic adenosis (SPA) of salivary glands is a tumorous lesion of salivary glands, with clinical presentation of a slow-growing mass characterized by a combination of histological features, some of which are reminiscent of mammary fibrocystic disease. SPA is mostly unifocal, but rarely may be multifocal and/or bilateral. Recurrences have been reported in up to 19% of cases. Although originally considered pseudoneoplastic, the occurrence of "dysplasia" and carcinoma in situ of ductal epithelium, and recent evidence of clonality suggest a possible neoplastic nature. Herein we describe, for the first time, two cases of SPA in two sisters (7 and 33 years old). The younger patient experienced multiple recurrences. This is the first report of familial occurrence of SPA, suggesting a possible genetic background.

Salivary gland tumours: 25 years of experience from a single institution in Croatia.

INTRODUCTION: The aim of this study was to determine the types, frequency, distribution, and demographic characteristics of salivary gland tumours in a large representative sample. PATIENTS AND METHODS: We retrospectively analysed the medical records of 779 patients with tumours of the salivary glands surgically treated from 1985 to 2009 at a single institution. RESULTS: There were 500 benign and 279 malignant tumours. The average age of patients with benign tumours was 50 years and of malignant salivary gland tumours 56 years. No differences in age and incidence of tumours existed between males and females. The majority of the tumours occurred in the parotid gland (509), followed by the minor salivary glands (212), the submandibular gland (51) and lastly, the sublingual gland (7). Minor salivary gland tumours occurred most frequently on the palate, the pleomorphic adenoma being the most frequent benign tumour type and the adenoid cystic carcinoma being the commonest malignant tumour. Tumours of the sublingual gland were rare, but all were malignant. Malignant tumours were more common in the minor salivary glands and the submandibular gland. CONCLUSION: This large study of salivary gland tumours in Croatia could improve our understanding of the significant differences in the global distribution of salivary gland tumours which have been reported.

The importance of team work of cytologist and surgeon in preoperative diagnosis of intraoral minor salivary gland tumours.

Tumours arising from oral minor salivary glands may exhibit an overlap of clinical and morphological features that may produce diagnostic and therapeutic dilemmas. The aim of this study is to asses the value of fine needle aspiration cytology (FNAC) in differentiation of benign and malignant tumours and to render a specific diagnosis. We evaluated the team work of surgeon and cytologist to improve diagnostic accuracy. Two steps are important for accuracy: sampling aspirate that should be done together by surgeon and cytologist and cytological microscopic analysis of the smears that should be performed by an experienced cytologist. The study included 132 patients with intraoral minor salivary gland tumours between 2002 and 2011. Adequate material was obtained from 121 (91.7%) patients. FNAC was usually performed by cytologist in a team with maxillofacial surgeon at cytology department that is more convenient for preparing the samples and especially for ROSE procedure (rapid-on site evaluation) of smears. In such a way the cytologist checked the adequacy of samples and decided whether some ancillary techniques should be used and therefore repeat FNAC. A total of 82 patients underwent surgery, 40 with malignant and 42 with benign tumours. Preoperative cytological diagnoses were compared with histopathological ones using histopathology as a gold standard. The most common benign tumour was pleomorphic adenoma and among malignant tumours adenoid cystic carcinoma. The most commonly affected site was the palate. The team work of surgeon and cytologist achieved specificity of 95.1%, sensitivity of 97.6% and diagnostic accuracy of 96.3%. We can conclude that although subclassification of some tumour types of salivary glands remains poor, FNAC is invaluable in patient triage and therefore should be considered in the first line investigations of these lesions by the cytologist and surgeon.

Melanotic neuroectodermal tumour of infancy: report of two cases and review of the literature.

Melanotic neuroectodermal tumour of infancy (MNTI) is an uncommon tumour affecting predominantly the craniofacial bones of the newborn infants. The neural crest origin of the tumour has been confirmed. MNTI is generally accepted as a benign tumour despite of its rapid and locally infiltrative growth. Recurrence rate varies between 10% and 60%, and malignant behaviour has been reported in 6.5% of MNTIs. Systematic review of the literature revealed 445 MNTIs published between 1918 and 2010. We present additional two cases of MNTI from our Department, typical in all terms, which equals a total number of 447 reported cases. One of our cases revealed histological features consistent with malignant behaviour, but at present, 18 months after the surgical excision, there is no evidence of recurrence. Biological behaviour of MNTI cannot be predicted by gross or histologic characteristics, thus early diagnosis and careful follow-up after the complete surgical excision is required.

Lifestyle habits and the risk of head and neck cancer in Zagreb region.

In 2002, International Agency for Research on Cancer launched a multicentric case-control study of head and neck cancer in 15 centres in 11 European countries, Croatia included. The Alcohol-related Cancers and Genetic Susceptibility in Europe (ARCAGE) study database with approximately 2500 case-control pairs is currently the largest head and neck cancer patients database in Europe. The aim of the present study was to estimate the risk of smoking and alcohol consumption in head and neck cancer patients from Zagreb region recruited in scope of the ARCAGE study. The cases (45 males, 9 females) and the controls (37 males, 9 females) were recruited from University Hospital Dubrava and Merkur University Hospital. A blood sample and a lifestyle questionnaire were collected from all study subjects. Data were analysed by logistic regression analysis. The distribution of cases was: 43 oral, 9 pharyngeal and 2 laryngeal cancer cases. Ever-smokers had a 4-fold higher cancer risk (adjusted OR 4.3 (CI 1.20-15.4)) compared to never-smokers. The adjusted odds ratio for alcohol consumption more than once a week was 4.1 (CI 1.5-11.2). The results are in keeping with previously published data from other countries.

Schwannoma of the tongue in a child.

A schwannoma or neurilemmoma is a benign, slow growing, usually solitary and encapsulated tumour originating from Schwann cells of the nerve sheath. Approximately 25-40% of all schwannomas are seen in the soft tissues of the head and neck, often originate from the acoustic nerve. Intraoral schwannomas are rare and account for 1% of schwannomas of the head and neck region. We report the case of a 10-year-old boy diagnosed with a schwannoma of the tongue. The purpose of this report is to emphasize the possibility of diagnosing schwannoma among all other lingual lesions in children. The disease itself was diagnosed histologically after complete surgical excision. Five years after surgical treatment, the patient is without signs of recurrence. This paper highlights the importance of a multidisciplinary approach in the diagnosis and surgical treatment of this very rare entity.

Primary synovial sarcoma of the parotid gland in 15-year-old boy.

Synovial sarcoma (SS) is a malignant mesenchymal tumour, predominantly found in the deep soft tissues of lower extremities, whereas only 3% occur in the head and neck region. Primary synovial sarcoma of the parotid gland is exceptionally uncommon. This is a report of a 15-year-old boy with a synovial sarcoma arising in the parotid gland, and, to the best of our knowledge, this is the youngest patient on record. The patient was treated primarily surgically, followed by chemotherapy and radiotherapy. Two years after this multimodal therapy, the patient is without signs of loco-regional recurrence or distant metastases. This paper highlights the importance of a multidisciplinary approach in the diagnosis and treatment of this very rare entity.

Fine needle aspiration cytology of chondroid syringoma.

Chondroid syringoma (CS) is a rare, benign, appendageal tumor with diagnostic feature of myxochondroid stroma supporting eccrine and apocrine epithelial structures. The usual presentation is a painless, slowly growing mass, typically located in the head and neck region. It usually affects middle-aged and older male patients. Because of its unremarkable clinical presentation it is often overlooked. It should be included in the differential diagnosis of cutaneous head and neck tumors, especially in middle-aged men. Optimal treatment of CS is total surgical excision. We present a 63 year-old man with a small nodule on the neck with 5 years of duration. The diagnosis was made initially on fine needle aspiration cytology that was performed by ultrasound guidance and confirmed subsequently by histology. FNA cytology may be very useful to determine diagnosis before excision.

Latissimus dorsi-scapula free flap for reconstruction of defects following radical maxillectomy with orbital exenteration.

A total of 21 patients with latissimus dorsi-scapula free flap reconstruction immediately following radical maxillectomy together with orbital exenteration are presented. Orbital exenteration was performed in all patients due to tumour invasion at the time of diagnosis. There was no total flap failure. Two tissue components subdivided into separate flap units with individual vascular pedicles linked by a single vascular source provide an ideal reconstructive solution for massive defects of the mid-face and orbit. Separate arcs of rotation of each flap unit permit greater mobility necessary for complex three-dimensional reconstruction. A vertically positioned angle of the scapula enables simultaneous reconstruction of the malar eminence and alveolar ridge whereas spontaneous intraoral epithelialisation of the latissimus dorsi muscle requires no additional procedure. For these reasons, in our opinion, combined latissimus dorsi-scapula free flap should be considered the first choice in reconstruction of defects following total maxillectomy with orbital exenteration.

Treatment of squamous cell carcinoma of the lip.

Tumors of the lip are squamous cell carcinomas in 95% of the cases. Also, in 95% of the cases they arise on a vermilion of the lower lip, because of greater exposure of the lower lip vermilion to direct, cumulative UV radiation which is main etiologic factor in development of squamous cell carcinoma. We have reviewed patients that have been treated for lower lip carcinoma at the Department for Maxillofacial surgery, University hospital "Dubrava", from 1990 to 2007. Most common surgical procedure was V-shaped excision of the lip with or without vermilionectomy. For more extensive tumors we used some of the reconstruction methods with local or distant flaps (Webster-Bernard, Karapandzic, free flap). Neck dissection was performed only in patients with clinically evident metastasis or large carcinoma. Although regional metastasis is rare, it significantly lowers five-year survival. Also, we found worse outcome in patients that have been treated previously elsewhere and came for surgical therapy because of recurrent/residual tumor or neck metastasis in comparison to those that were initially treated at the Department of Maxillofacial surgery.

The pectoralis major flap in head and neck reconstruction: first 500 patients.

AIM: The aim of this study was to evaluate almost 20 years of using the pectoralis major flap in head and neck reconstruction at the Department of Maxillofacial Surgery, Zagreb. PATIENTS: In the period from 1981 to 1999, a total of 506 pectoralis major flaps were used for head and neck reconstruction in 500 patients. In all cases the flap was used after surgical resection of an advanced malignant tumour of the head and neck. RESULTS: The tumours were intraoral in 387 cases (77%), pharyngeal in 78 cases (15%) and on the skin in 10 cases (5%). The defect was located in the mucosal lining in 407 (81%), skin in 43 (8%), both intra- and extraoral in 53 (10%) patients. Bone defects occurred in 65 patients. In 31 patients (6%), the pectoralis major flap was used in combination with other flaps (deltopectoral, tongue, trapezius and free flaps). Complications occurred with 168 flaps (33%), but total flap necrosis was only seen in 10 patients (2%). Surgical treatment of complications was necessary in 87 patients (17%). CONCLUSION: Despite the increasing use of microvascular reconstruction, the pectoralis major myocutaneous flap continues to be the most universal major flap in head and neck reconstruction.

The significance of salivary and serum interleukin 6 and basic fibroblast growth factor levels in patients with Sjögren's syndrome.

Role of various cytokines have been implicated in the development and perpetuation of Sjogren's syndrome (SS), but no specific cytokine could be determined as a major contributor to the SS. Salivary and serum interleukin 6 (IL-6) levels have been studied previously in patients with SS, but data upon salivary and serum basic fibroblast growth factor (bFGF) in SS are lacking. The aim of this study was to evaluate levels of salivary and serum IL-6 and bFGF in 18 patients with SS, age range 32-79, mean 54.05 years. Control group consisted of 23 healthy participants, mean age 25 years. Serum IL-6 and bFGF levels were not significantly different between patients with SS and healthy controls. Elevated levels of salivary IL-6 and bFGF in patients with SS when compared to the healthy controls were found (p<0.001). We might speculate that higher levels of salivary IL-6 and bFGF in patients with SS might originate from local production probably having source in the salivary glands.
