    Opis:
    Vascular tumours and malformations are revealed at birth and do not subside. The aim of the study was to present the principles and outcomes of treatment of patients with arteriovenous malformations treated at the Clinic of Plastic Surgery in Polanica Zdrój in the years 2009- 2010. Only one patient, who had not been treated previously, had the lesion on the cheek removed subtotally and the defect was closed by means of local repair. In the remaining patients, with primary lesions located in the auricle, scalp, and cheeks, the indications for operation included recurrent infections, ulcerations, and first of all, massive, life-threatening haemorrhages. All the patients, treated for many years in other centres, had underwent numerous resection procedures, vessel ligations, embolizations and obliterations. The patients were followed up after the surgery every 6 months. The therapy aim was achieved in all the patients. Vascular tumours were removed totally or subtotally, the lost structures were reconstructed and permanent healing of the wound was achieved. None of the patients developed recurrence of the disease, infection, or bleeding.

    Opis:
    Hemangiomas belong to one of the most common type of tumors occurring in childhood. They are benign and often do not require any treatment, with the tendency to. frequently disappearing spontaneously at the age of 5-7 years. The tumors usually develop in the head and neck area, whereas vascular malformations (AVMs) are rare congenital anomalies, which may occur anywhere. In upper limb, they may amount to 30-60% of cases. It is common for these changes not to require any surgical treatment. In case they do, the main indications for such treatment of upper limb AVMs may be as follows: signs of compression of the peripheral nerves, limited mobility of the fingers because of the tumor, which entails difficulties in the functioning of the whole arm, pain and aesthetic considerations. Aim of the study was to present the results of surgical treatment of vascular tumors (hemangiomas and AVMs) in the upper limb that was applied in our department, as well as a broader discussion on epidemiology, diagnosis, and treatment of these changes. Material and methods. In 2003-2011 period we treated 11 patients aged 24-39, suffering from vascular tumors (hemangiomas / vascular malformations) in the upper limb; the group included 3 men and 8 women. In this group we diagnosed 2 cases with arm hemangiomas, 2 cases of intramuscular hemangiomas of the forearm, 2 cases of hemangiomas in metacarpal area, 2 cases of AVMs of the finger and metacarpal area, and 4 cases of isolated vascular malformations (mainly arteriovenous malformations) of the fingers. All preparations were examined histologically. Results. No complications or recurrence were found in 7 cases, recurrences of AVMs were observed in 4 patients with finger changes. In one patient with AVMs of the index finger, we observed a treble recurrence, which severely impaired functioning of his hand. We eventually suggested to him the finger amputation, to which the patient agreed Conclusions. Upper extremity is a rare location of hemangiomas and other vascular malformations requiring surgery. hemangiomas are more common in women, and the occurrence of AVMs in both males and females is similar. Surgical treatment of hemangiomas and AVMs of the upper extremities is doubtlessly an arduous task, which calls for great microsurgical skills.

    Opis:
    Introduction: Some patients with profound sensorineural hearing loss have inner ear malformations. Initially, those were believed to be a contradiction to cochlear implantation. However, with the advance of cochlear implant surgery and technology, it has become possible to treat this group of patients. However, cochlear implantation in the case of inner ear malformations can be associated with numerous surgical difficulties and possible complications. Purpose: The paper aims to present: (1) modern classification of inner ear malformations, (2) surgical and clinical challenges related to all types of malformations, and (3) cases of inner ear malformations identified in the authors’ centers. Material and methods: Of 111 children enrolled for cochlear implantation in three clinical centers, a group of patients with malformations of the inner ear was selected. We analyzed: preoperative imaging studies of patients performed prior to cochlear implantation, hearing tests, surgical protocols of cochlear implantation, results of intraoperative measurements and intraoperative imaging studies. We discuss what is currently believed to be the leading classification of inner ear malformations. Results: In 19/111 (17%) children, we diagnosed severe inner ear malformations in 35 ears. In 13/19 (68%) patients the malfor mations were bilateral and symmetrical, while 6/19 (32%) patients had different malformations in the right and left ear or one-sided malformation. All inner ear malformations described in the classification were found, except for rudimentary oto cyst. The most common are: cochlear hypoplasia, incomplete partition, and enlarged vestibular aqueduct. Discussion: Severe inner ear malformations are a major diagnostic and clinical challenge in children qualified for cochlear implantation. They can preclude or considerably complicate cochlear implantation and postoperative care. Inner ear malformations are found in imaging studies even in 20 to 30% of patients with profound hearing loss.

    Opis:
    Introduction: Preoperative imaging, besides audiological evaluation, plays a major role in evaluation of candidacy for auditory implants, and in particular cochlear implants. It is essential to assess whether the basic criteria necessary for implantation are met. Diagnostic imaging is crucial not only in determining candidacy, but also determining the feasibility of cochlear implantation as it allow to anticipate surgical difficulties which could preclude or complicate the implantation of the device. The aim of the study is to present the protocol for the evaluation of preoperative imaging studies with particular focus on the factors potentially affecting clinical decisions in children qualified for cochlear implantation. Material and method: Preoperative imaging studies of 111 children performed prior to cochlear implantation were analyzed: high-resolution computed tomography (HRCT) of temporal bones and MRI. The assessment was made according to the presented protocol. Results: Pathologies and anomalies identified during the assessment of preoperative imaging studies significantly altered clinical decisions in 30% of patients. In the study group, in 17% of patients inner ear malformations were identified. 2.7% of children were disqualified from a cochlear implantation due to severe congenital inner ear malformations. 9% of the patients have had bacterial meningitis. In 50% of them difficulties related to complete or progressive cochlear ossification occurred. In 4.5% of patients less common surgical approaches other than mastoidectomy with a posterior tympanotomy were applied. Discussion: Preoperative imaging allow for the identification of significant pathologies and anomalies affecting qualification decisions and further treatment. HRCT and MRI are complementary to each other for preoperative imaging. The two modalities in combination allow accurate and optimal evaluation of the anatomical structures prior to implantation. Inner ear malformations and cochlear ossification following meningitis are relatively frequently encountered in children qualified for a cochlear implant.

    Opis:
    The 5p deletion syndrome (5p-, Cri-du-chat syndrome, CdCS) is a genetic disorder which results from a partial deletion of the short arm of chromosome 5. It was first described by Lejeune et al. in 1963. The incidence ranges from 1:15 000 to 1:50 000 live births. The 5p- is usually diagnosed in the first days of life because of the characteristic monotonous high pitched cat-like cry and relatively constant dysmorphic features. Other symptoms often present in the neonatal period include low birth weight, muscle hypotonia, asphyxia and feeding difficulties due to impaired suction and swallowing, which may all lead to failure to thrive. Organ malformations, with various larynx abnormalities, although not very frequent, can also be present. Symptoms that are prevalent in later life include severe motor delay and intellectual disability with significant speech impairment, as well as behavioral problems. The case report presents a female infant in her 5th month of life in whom, despite the typical symptoms of 5p-, stridor and episodes of choking were the main problems. Laryngotracheal endoscopy revealed the type I laryngeal cleft. Genetic analysis confirmed the diagnose of 5p- syndrome. The presented case shows that it is critically important to perform a further investigation and refer a child with laryngological problems coexisting with dysmorphic features to a clinical geneticist.
