Opis:
A 44-year-old male presented with a facial schwannoma extending into both the middle cranial fossa and mastoid processus. Due to hearing loss, facial nerve palsy and inflammatory changes in CT scan, this patient was misdiagnosed as chronic otitis media. Audiogram showed a right mixed hearing loss with 30–40 dB air-bone gap. In MR, features of the facial nerve neuroma were found. The patient was qualified for surgery to remove the tumor via middle fossa approach, with possible conversion to the retroauricular approach. Ossiculoplasty LC was performed. Diagnostic problems and methods of treatment are discussed.

Opis:
Our aim was to test existing sex and age stereotypes related to emotional expressivity, gender and age. This was a complex analysis of facial expressions of all basic emotions (anger, disgust, fear, happiness, sadness, and surprise) to everyday life stimuli observing a large sample (2,969 unique participants creating 39,694 recordings) using an Emotion Artificial Intelligence. Our data partially support emotion-specific stereotype that women express more affiliate emotions and men express more dominant emotions except for sadness. There were found correlations of emotion expression with age, however intensity and frequency of emotion expression did not follow the same pattern. Not eliminating the differences between men and women in the baseline facial appearance resulted in men expressing dominant emotions (anger and disgust) more intensively, and women expressing more affiliative emotions (happiness, fear, and surprise). To sum up, facial appearance can be one of the origins of the existing gender stereotypic socialisation stereotype.

Opis:
As android robots become increasingly sophisticated in their technical as well as artistic design, their non-verbal expressiveness is getting closer to that of real humans. Accordingly, this paper presents results of two online surveys designed to evaluate a female android’s facial display of five basic emotions. Being interested in intercultural differences we prepared both surveys in English, German, as well as Japanese language, and we not only found that in general our design of the emotional expressions “fearful” and “surprised” were often confused, but also that Japanese participants more often confused “angry” with “sad” than the German and English participants. Although facial displays of the same emotions portrayed by the model person of Geminoid F achieved higher recognition rates overall, portraying fearful has been similarly difficult for her. Finally, from the analysis of free responses that the participants were invited to give, a number of interesting further conclusions are drawn that help to clarify the question of how intercultural differences impact on the interpretation of facial displays of an android’s emotions.

Opis:
Introduction: The most common mechanism of post-traumatic facial nerve palsy are road accidents and falls. Treatment schemes as well as proper timing of surgery are still controversial. Aim: The aim of the study was the evaluation of the effects of surgical treatment in patients with post-traumatic facial nerve palsy. Treatment results were correlated with epidemiological factors, mechanism of injury, level of nerve damage, time of surgery and its extent. Material and methods: 9 patients with facial nerve palsy after head trauma were analyzed. In all patients complete paresis of the VII nerve occurred immediately after the injury. In 5 patients the nerve was damaged in the course of the longitudinal fracture of the temporal bone, in 3 as a result of its transverse fracture while in one woman there was no evident fracture line. In all cases, surgical treatment was performed between 4 days and 13 weeks after the trauma. In all cases transmastoid approach was used. Edema lesions of the nerve dominated in 6 patients, in two cases a bone fragment was noted along its course, in one person nerve was disrupted but primary reconstruction was not possible – the man was excluded from further analysis. The results of treatment were assessed by House-Brackmann (HB) scale 12 months after the procedure. Results: Very good (HBI) or good (HBII) recovery of facial nerve function was achieved in 2 and 4 out of 8 patients respectively. Surgical timing, the extent of surgery, patient’s age, mechanism of injury and level of nerve damage had no effect on the final outcome. Conclusions: The management of post-traumatic facial nerve palsy should be individual. The commonly accepted recommendation on surgical treatment is to undertake it in patients with immediate-onset and complete paralysis. Patients who, due to their severe general condition, cannot undergo early facial nerve decompression may benefit from delayed treatment for up to 3 months after the injury.

Opis:
In this study, we propose to diagnose facial nerve palsy using Support Vector Machines (SVMs) and Emergent Self-Organizing Map (ESOM). This research seeks to analyze facial palsy domain using facial features and grade the degree of nerve damage based on the House-Brackmann score. Traditional diagnostic approaches involve a medical doctor recording a thorough history of a patient and determining the onset of paralysis, rate of progression and so on. The most important step is to assess the degree of voluntary movement of the facial nerves and document the grade of facial paralysis using House- Brackmann score. The significance of the work is the attempt to understand the diagnosis and grading processes using semi-supervised learning with the aim of automating the process. The value of the research is in identifying and documenting the limited literature seen in this area. The use of automated diagnosis and grading greatly reduces the duration of medical examination and increases the consistency, because many palsy images are stored to provide benchmark references for comparative purposes. The proposed automated diagnosis and grading are computationally efficient. This automated process makes it ideal for remote diagnosis and examination of facial palsy. The profiling of a large number of facial images are captured using mobile phones and digital cameras.

Opis:
In 1976 Dr. Paul Tessier described numeric classification for rare craniofacial clefts. He first emphasized that a fissure of the soft tissue corresponds, as a general rule, to a cleft of the bony structure. The classification, easy to understand, became widely accepted because the recording of the malformations was simple and facilitated communication between observers. The aim of this study was to present our own experience with treatment of patients with rare facial clefts. Material and methods. Our Department has 11 patients with rare craniofacial clefts under its care. This group includes 8 boys and 3 girls. The patients aged from 2 months to 18 years at the time of the first consultation. Results. In two patients the cleft was median, in seven patients it was one-sided and in two – bilateral. The most common type of cleft was number 6, and the rarest were 2, 3, and 7. All patients underwent surgical treatment. Conclusions. Atypical facial clefts are rare congenital anomalies, however because of functional and aesthetic disturbances they constitute a serious medical and therapeutic problem. Facial clefts are characterized by variable clinical presentation and require individualized treatment plan.

Objective: Congenital cholesteatomas of the petrous apex are rare lesions that develop insidiously, which delays diagnosis and requires a high index of suspicion. A case report of supralabyrinthine congenital petrous bone cholesteatoma and review of recent literature are presented. Methods: A 27-year-old woman presented with progressive facial palsy. Otomicroscopy did not reveal any abnormalities, and hearing was normal. Although there were no complaints of vertigo or instability, vestibular examinations indicated a non-compensated peripheral vestibular lesion. Radiological examinations revealed a lesion in the petrous apex and epitympanum that had features of a cholesteatoma. Results: To preserve normal hearing, the middle fossa approach was chosen for surgery. A damaged part of the facial nerve was reconstructed with cable graft. Conclusion: Advances in radiological imaging facilitate surgical planning, and improvements in the techniques of lateral skull base surgery enable safe and radical removal of petrous bone cholesteatomas with minimal morbidity.

Opis:
Aging has profound effects on facial biometrics as it causes change in shape and texture. However, aging remains an under-studied problem in comparison to facial variations due to pose, illumination and expression changes. A commonly adopted solution in the state-of-the-art is the virtual template synthesis for aging and de-aging transformations involving complex 3D modelling techniques. These methods are also prone to estimation errors in the synthesis. Another viable solution is to continuously adapt the template to the temporal variation (ageing) of the query data. Though efficacy of template update procedures has been proven for expression, lightning and pose variations, the use of template update for facial aging has not received much attention so far. Therefore, this paper first analyzes the performance of existing baseline facial representations, based on local features, under ageing effect then investigates the use of template update procedures for temporal variance due to the facial age progression process. Experimental results on FGNET and MORPH aging database using commercial VeriLook face recognition engine demonstrate that continuous template updating is an effective and simple way to adapt to variations due to the aging process.

Let G be a plane graph. A facial path of G is a subpath of the boundary walk of a face of G. We prove that each plane graph admits a 3-coloring (a 2-coloring) such that every monochromatic facial path has at most 3 vertices (at most 4 vertices). These results are in a contrast with the results of Chartrand, Geller, Hedetniemi (1968) and Axenovich, Ueckerdt, Weiner (2017) which state that for any positive integer t there exists a 4-colorable (a 3-colorable) plane graph Gt such that in any its 3-coloring (2-coloring) there is a monochromatic path of length at least t. We also prove that every plane graph is 2-list-colorable in such a way that every monochromatic facial path has at most 4 vertices.

Opis:
A facial rainbow edge-coloring of a plane graph G is an edge-coloring such that any two edges receive distinct colors if they lie on a common facial path of G. The minimum number of colors used in such a coloring is denoted by erb(G). Trivially, erb(G) ≥ L(G) + 1 holds for every plane graph without cut-vertices, where L(G) denotes the length of a longest facial path in G. Jendrol’ in 2018 proved that every simple 3-connected plane graph admits a facial rainbow edge-coloring with at most L(G) + 2 colors, moreover, this bound is tight for L(G) = 3. He also proved that erb(G) = L(G) + 1 for L(G) ∉ {3,4, 5}. He posed the following conjecture: There is a simple 3-connected plane graph G with L(G) = 4 and erb(G) = L(G) + 2. In this note we answer the conjecture in the affirmative. Keywords: plane graph, facial path, edge-coloring.

Opis:
This research aimed at testing multiple fitness hypothesis of attraction, investigating relationship between male facial characteristic and female students' reported readiness to engage in various social relations. A total of 27 male photos were evaluated on five dimensions on a seven-point Likert-type scale ranging from -3 to 3, by convenient sample of 90 female students of University of Sarajevo. The dimensions were: desirable to date – not desirable to date; desirable to marry – not desirable to marry; desirable to have sex with – not desirable to have sex with; desirable to be a friend – not desirable to be a friend; attractive - not attractive. Facial metric measurements of facial features such as distance between the eyes, smile width and height were performed using AutoCad. The results indicate that only smile width positively correlates with desirability of establishing friendship, whilst none of the other characteristics correlates with any of the other dimensions. This leads to the conclusion that motivation to establish various social relations cannot be reduced to mere physical appearance, mainly facial features, but many other variables yet to be investigated.

Opis:
The report aims to present a rare case of facial nerve schwannoma within the parotid gland. Schwannomas are benign, welldefined tumours arising from Schwann cells that form the myelin sheaths of peripheral, cranial or spinal nerves. 25–45% of them are located within the head and neck, mainly in the parapharyngeal space. The intraparotid localisation is rare. The aetiology of cancer is unknown. Preoperative diagnosis, both radiological and cytological, is difficult and often does not give the correct diagnosis. Radiologically, a multiform adenoma is usually suspected, and fine needle aspiration biopsy is nondiagnostic. Due to the rarity and benign nature of the tumour, there has been debate over the need for surgical treatment.

Opis:
Let G be a cellular embedding of a multigraph in a 2-manifold. Two distinct edges e1, e2 ∈ E(G) are facially adjacent if they are consecutive on a facial walk of a face f ∈ F(G). An incidence of the multigraph G is a pair (v, e), where v ∈ V (G), e ∈ E(G) and v is incident with e in G. Two distinct incidences (v1, e1) and (v2, e2) of G are facially adjacent if either e1 = e2 or e1, e2 are facially adjacent and either v1 = v2 or v1 ≠ v2 and there is i ∈ {1, 2} such that ei is incident with both v1, v2. A facial incidence coloring of G assigns a color to each incidence of G in such a way that facially adjacent incidences get distinct colors. In this note we show that any embedded multigraph has a facial incidence coloring with seven colors. This bound is improved to six for several wide families of plane graphs and to four for plane triangulations.

Opis:
Emotion may be treated as a special sort of message considering that communicative function is one of the basic functions of emotion. Moreover emotion serves as a message in two ways. In one way facial expression of emotion is a message to other participants of social interaction that contains information about the emotional state of the subject and thus plays important interpersonal role. It shows the subject’s personal attitude and amplifies verbal messages or makes them more credible. Numerous empirical studies show that processes of generating and perceiving of facial expressions of emotions are autonomic and specific. In the other way emotion is an internal message containing information about the significance of events or thoughts and thus helping in making choices or taking decissions.

Opis:
Presented studies investigated the specificity of visual and auditory modalities in attentional processing of emotion, and its association with temperamental dimensions and trait-like attentional control (AC). During preliminary study 30 participants were presented with the paper-pencil visual search task (Emotional Faces Attentional Test) and emotional prosody detection tasks (Emotional Prosody Test). Results revealed visual happiness superiority and auditory sadness superiority. During the main study, in addition to attentional performance, 51 subjects were administrated two questionnaires: EPQ-R and Attentional Control Scale. Introducing individual differences into analysis limited the general pattern of modality distinctiveness in attentional processing of emotional stimuli obtained in the preliminary study. Findings for all personality traits studied separately showed that Extraversion and low Neuroticism were associated with the visual sadness superiority. Whereas interactional analysis indicated effective visual threat processing in extraverts with good AC and effective friendly prosody detection when Neuroticism and AC remain in inverse relationship. Hence, we have found that processing emotional targets in both modalities is associated with temperament dimensions and their interactions with attentional control. Additionally, findings from both studies suggest that general psychological laws might be challenged by individual differences.
