Abstract 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.
Abstract 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.
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.
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 Šercer in 1950, five years before Millard's publication. Professor Ante Šercer 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.
An 11-year-old girl was referred because of a painless firm swelling in the right posterior mandible that had started 2 months previously. A panoramic radiograph showed a nonspecific finding of a ...tiny discreet shadow following the lower border of the mandible, without any radiographic signs of radiolucency in the affected area or discontinuity of the lower border. However, multislice computed tomography (MSCT) findings were suggestive of an aneurysmal bone cyst, and histopathological findings revealed a diagnosis of aneurysmal bone cyst. Complete surgical excision followed by extensive cortical bone curettage was done, and no recurrence has been observed in the past 5 years. A differential diagnosis list is included, and extended with fibrous dysplasia according to the radiographic findings. To the best of our knowledge, this is the first case of a jaw aneurysmal bone cyst with unusual initial radiographic findings. Furthermore, a ground-glass appearance on MSCT scans suggested fibrous dysplasia. The present case highlights the need for accurate differential diagnosis of the lesion described to obtain the correct diagnosis in a timely manner and plan the appropriate treatment.
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.
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.
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%).
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.

Abstract 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.
Abstract 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.
Rane tehnike zatvaranja rascjepa usne uključuju linearnu ili druge oblike geometrijskih linija (trokutasta ili četvrtasta zatvaranja). Prekretnica u operaciji rascjepa usana počela je 1955. godine ...kada je, na Prvom međunarodnom kongresu za plastičnu kirurgiju u Stockholmu, dr. Millard predstavio svoju metodu – klizno-rotirajuću tehniku ili režanj. Danas tu tehniku diljem svijeta, s modifikacijama ili
bez njih, primjenjuje više od 85 posto kirurga za rascjepe. predstavljamo pacijenta s potpunim jednostranim rascjepom usne i nepca koji je operiran prije šezdeset i pet godina. Ožiljak na usni sličan je klizno-rotirajućoj liniji. Plastiku usne obavio je profesor Šercer 1950., pet godina prije Millardove publikacije. Profesor Ante Šercer međunarodno je poznat otorinolaringolog iz Hrvatske. Ističe se njegov značajan doprinos operaciji velofaringealne insuficijencije i plastičnoj kirurgiji nosa i uha.
