Intracranial extension of Schneiderian inverted papilloma: a case report and literature review

Inverted papilloma is an uncommon primary nasal tumor. Despite its benign nature, this tumor represents three typical characteristics: a high propensity of recurrence, local aggressiveness and association with malignancy. Inverted papilloma can reduce the patient’s quality of life due to compromised nasal function, extension to the orbit and brain. The authors reported the unusual case of a 72-year-old male patient with inverted papilloma, which fatally extended to the intracranial temporal fossa after multiple recurrences. To the authors’ knowledge, this is the twelfth case in the literature of inverted papilla extending into the temporal fossa. The current and pertinent literature in English, French and German was reviewed, and an algorithm for managing inverted papilloma was also proposed

Is radical surgery of an inverted papilloma of the maxillary sinus obsolete? a case report

Abstract Background Sinonasal inverted papilloma is a locally aggressive tumor arising from the Schneiderian membrane which lines the nasal cavity and paranasal sinuses. Aggressive surgical approaches, such as lateral rhinotomy, were used until recently for complete removal of the inverted papilloma. Currently, endoscopic resection is the gold standard in the treatment of inverted papilloma. However, there are situations that justify an open approach. For example there are studies that report a higher postoperative recurrence rate after endonasal endoscopic resection, particularly in the treatment of recurrent diseases. While endoscopic resection performed by an experienced surgeon is definitely a minimally invasive therapy, an open approach is not necessarily associated with functional and aesthetic disadvantages. This case report describes the treatment of inverted papilloma by an open approach. This has been described before but the new gold standard of endoscopic resection has to be taken into account before any treatment decision is made nowadays. Case presentation Contrast-enhanced magnetic resonance imaging of the head and neck area was indicated in a 72-year-old white German man who presented with suspected squamous cell carcinoma of his lower lip. Magnetic resonance imaging additionally revealed a 3×2 cm2 polycyclic arranged mucosal thickening with cystic and solid contrast affine shares at the antral laterocaudal area of his right maxillary sinus, extending from his right lateral nasal wall to his maxillary sinus floor. He received antral polypectomy with medial maxillectomy via a unilateral LeFort I osteotomy approach. His pterygoid plate was preserved. A histological examination demonstrated a tumor composed of hyperplastic squamous epithelium protruding into the stroma (surface epithelial cells grew downward into the underlying supportive tissue), thus producing a grossly convoluted cerebriform appearance. Two weeks later, the patient regained a well-formed maxilla without any restrictions. He has remained disease-free for 25 months following the surgery and surveillance was continued in our tumor clinic. Conclusions Endoscopic resection of an inverted papilloma continues to be the gold standard. However, some cases require a radical approach. This does not necessarily increase patient morbidity

Endoscope-Assisted Submandibular Sialadenectomy: A Review of Outcomes, Complications, and Ethical Concerns

Objectives: To review outcomes and complications of endoscope-assisted submandibular sialadenectomy (EASS) and to analyze this innovative technique with regard to ethical issues. Methods: We used a systematic review study design to identify clinical studies on EASS, published in English, French, German, and Thai. The last electronic search was conducted in September 2009. We checked the bibliographies of the identified articles, relevant local journals, and congress abstracts. Publications were further assessed and assigned their respective levels of evidence. We also investigated reporting on human subject protection, conflicts of interest, funding support, and commercial relationships. Results: Five case series reporting a total of 28 patients met the inclusion criteria. There was no need of recourse to open surgery. All of the authors claimed satisfactory cosmetic results. Complications were uncommon. However, no controlled trial was available, and outcome measures varied between studies. Human subject protection and funding sources were mentioned in only 2 articles. Commercial relationships and conflicts of interest could not be identified. Conclusions: All of the reports favor outcomes of EASS. However, their level of evidence is low, and the superiority of this procedure over the conventional surgery remains unknown. The success of this procedure should not be overemphasized in information for consent and mislead surgeons to begin it without adequate training and elaborate environment. The lack of ethical documentation creates a high degree of suspicion of the studies

Analysis of Facial Characteristics of Female Beauty and Age of Mona Lisa Using a Pictorial Composition

Aims: The purpose of this study was to investigate the age of the Mona Lisa and the effect of painting composition on her beauty in terms of facial femininity, youthfulness, and attractiveness. Study Design: We used a longitudinal study design. Place and Duration of Study: We enrolled a random sample of dental students at the University of Leipzig, Faculty of Dental Medicine, between January 2015 and January 2016. Methodology: The predictor variable was the portrait composition. To make the painting different, we substituted the faces in two other portraits (one male, Christian IV, Duke of Zweibrücken, and one female, Marie-Suzanne Giroust-Roslin) with that from the Mona Lisa. The outcome variables were estimated age, facial femininity, youthfulness, and attractiveness of the Mona Lisa. Appropriate descriptive and univariate statistics were calculated. The level of statistical significance was set at P ≤ 0.05. Results: The sample comprised 107 subjects (76 females, 71%; 31 males, 29%) with a mean age of 24.8 ± 2.6 years. The panel estimated the Mona Lisa’s age at 32.3 ± 5.6 years. Facial femininity, youthfulness, and attractiveness were affected by painting composition (P < 0.05). Conclusion: The results of this study suggest the Mona Lisa’s face is that of a woman in middle-aged adulthood. Her facial femininity, youthfulness, and attractiveness depend on the composition of the painting

Paget ́s disease of the mandible: A differential diagnosis of the osteomyelitis of the jaw

Der Morbus Paget ist eine verbreitete, progre­ diente Knochenerkrankung unklarer Ätiologie. Charakteristisch ist ein Umbau von regulären Skelettarealen in hypervaskularisierten Knochen verminderter Dichte. Zu den häufigsten Sympto­ men zählen Knochenschmerzen, welche eine Fol­ ge der periostalen Reizung infolge des gesteiger­ ten Stoffwechsels sind. Gleichwohl kann die Erkrankung asymptomatisch verlaufen. In diesen Fällen können auffällige radiologische Befunde oder eine exzessiv erhöhte alkalische Phosphata­ se zur Diagnose führen. In den meisten Fällen wird die Erkrankung zufällig entdeckt. Der Al­ tersgipfel der Erkrankung liegt bei circa 50 Jah­ ren, wobei das männliche Geschlecht bevorzugt befallen wird. Der Morbus Paget kann in isolierten (monostotisch) ebenso wie in multiplen Skelett­ arealen (polyostotisch) auftreten. Typische Loka­ lisationen sind Becken, Femur und Lendenwirbel­ säule, weniger häufig sind Schädel und Tibia betroffen. Im Kopf­Hals­Bereich sind Läsionen des Hirnschädels häufiger also solche in Ober­ bzw. Unterkiefer. Im Vordergrund der Behandlung des Morbus Paget steht der Einsatz antiresorpti­ ver Wirkstoffe, insbesondere von Bisphosphona­ ten. Zusätzlich ist häufig eine symptomatische Therapie mit analgetischen, antiphlogistischen bzw. antineuropathischen Wirkstoffen angezeigt. Vorgestellt wird ein Patient mit polyostotischem Morbus Paget der Mandibula und des Thorax.Paget ́s disease of bone is a common, progressive disorder with uncertain etiology. It results in the replacement of normal skeletal areas with highly vascularized, low density bone. The most frequent symptom is bone pain, which is a result of periostal irritation due to increased metabolic activity. However, the disease may run without any symptoms. In these cases, an abnormal radiograph or an elevated serum alkaline phosphatase can indicate the disorder. Most cases are discovered accidentally. The average age of patients at the time of diagnosis is about50 years. Male individuals are preferentially diseased. Paget ́s disease affects either single bone (monostotic) or many bones (polyostotic). It typically involves the pelvis, femur and lumbar spine rather than skull and tibia. In the head and neck area, the skull is the most frequently affected localization. Lesions of the mandible and maxilla are less common. For the therapy of active Paget ́s disease, antiresorptive agents like bisphosphonates are effective drugs. Additional treatment with analgesic drugs, antiinflammatory and antineuropathic agents is recommended. We present a case of polyostotic Paget ́s disease of the mandible and of the thoracic skeleton
