RESUMO

Basal cell carcinoma is the most common malignant skin tumor of the eyelids in Caucasians, followed by squamous cell carcinoma and sebaceous gland carcinoma. The primary treatment for these tumors is radical excision. In cases where malignant eyelid tumors are advanced and have invaded the orbit, orbital exenteration is necessary. In this retrospective study, we aimed to determine the correlation between the risk of orbital infiltration and various factors like tumor location, size, histological type, and patient age. This study revealed that tumors in multiple regions increased the risk of orbital infiltration by 3.75 times. Tumors with a diameter of 21-30 mm raised the likelihood of requiring exenteration by 15.5 times compared to smaller tumors (up to 10 mm). Age was also associated with the likelihood of orbital invasion in periocular tumors. Interestingly, no correlation was found between the histological type of the tumor and the risk of orbital infiltration. Notably, the conjunctiva of the eyeball was the most commonly infiltrated orbital structure, followed by the orbital fat. Timely treatment and well-planned procedures are crucial for patients with malignant periocular skin tumors to avoid multiple reoperations and the potential need for orbital exenteration.

RESUMO

BACKGROUND: Diagnostic errors constitute one of the reasons for the improper and often delayed treatment of mandibular fractures. The aim of this study was to present a series of cases involving undiagnosed concomitant secondary fractures in the mandibular body during preoperative diagnostics. Additionally, this study aimed to describe the "air sign" as an indirect indicator of a mandibular body fracture. METHODS: A retrospective analysis of CT/CBCT scans conducted before surgery was performed on patients misdiagnosed with a mandibular body fracture within a one-year period. RESULTS: Among the 75 patients who underwent surgical treatment for mandibular fractures, mandibular body fractures were missed in 3 cases (4%) before surgery. The analysis of CT/CBCT before surgery revealed the presence of an air collection, termed the "air sign", in the soft tissue adjacent to each misdiagnosed fracture of the mandibular body. CONCLUSIONS: The "air sign" in a CT/CBCT scan may serve as an additional indirect indication of a fracture in the mandibular body. Its presence should prompt the surgeon to conduct a more thorough clinical examination of the patient under general anesthesia after completing the ORIF procedure in order to rule-out additional fractures.

RESUMO

(1) Background: Stylohyoid syndrome, known as classical Eagle Syndrome (cES), is characterized by calcification of the stylohyoid chain with numerous nonspecific symptoms, mainly pain. This study introduces minimally invasive cervical styloidectomy (MICS). (2) Methods: MICS was performed on sixty-five patients diagnosed with classical Eagle Syndrome. Patients underwent meticulous differential diagnosis. Surgical plans were established based on the findings from neck angioCT. (3) Results: The healing process was uneventful, without significant complications. The overall success rate was 97.0%, with a follow-up of a minimum of six months. In one case, the surgery did not yield the desired improvement. In one case, a partial relapse of symptoms was observed. (4) Conclusions: MICS is a straightforward and efficient surgical treatment technique for stylohyoid syndrome.

RESUMO

Cystic lesions observed in parotid glands are relatively rare and comprise 2-5% of all parotid primaries. A salivary duct cyst (SDC) is a true cyst representing 10% of all salivary gland cysts. The risk of malignant transformation of SDC's epithelium is extremely rare. In the literature, only three cases of carcinoma ex SDC of the parotid gland are described. This report presents the first in the literature case of myoepithelial carcinoma (MECA) arising from a parotid SDC. A 75-year-old male patient was referred to the Department of Cranio-Maxillofacial Surgery of the Jagiellonian University in Cracow, Poland due to a cystic tumor arising from the right parotid gland. Superficial parotidectomy with facial nerve preservation was performed. Histological examination confirmed a rare case of MECA emerging from the SDC. The immunohistochemical profile of MECA ex SDC was presented. During 6 months of the follow-up, local recurrence or distant metastasis was not observed.

RESUMO

Introduction Extraparotid Warthin tumor (WT) is a very rare entity, especially when synchronous with oral cancer (OC). Objective The present study presents a case series of extraparotid WTs detected in the surgical specimen of patients treated for OC. Methods From 2007 to 2016, 336 patients were operated for OC in our institution. Neck dissection was performed in 306 patients. Results In the 306 patients operated for OC whose necks were dissected, unexpected WTs were observed in 4 surgical neck specimens. In 3 cases, extraparotid WTs were responsible for tumor, node, metastasis (TNM) overstaging before surgery. Conclusion Extraparotid WTs may be discovered during neck dissection in ∼ 1% of OC patients, and they may mimic neck metastasis, especially in positron-emission tomography/computed tomography (PET/CT) imaging.

RESUMO

BACKGROUND: Salvage surgery with reconstruction of the second and next primary tongue cancer remains difficult, especially after earlier neck dissection and radiotherapy. In the current report, we describe the feasibility of the extended, double-pedicled facial artery musculomucosal (dpFAMM) flap in the reconstruction of the patient with second primary tongue squamous cell carcinoma, after facial vessel ligation and radiotherapy. CASE PRESENTATION: An 81-year-old female patient was operated on due to tongue squamous cell carcinoma (SCC) on the left side T3N1M0 in 2019. Bilateral selective neck dissection with tongue reconstruction was performed by island FAMM flap. The patient also suffered from synchronous mucinous breast carcinoma treated with tamoxifen. The second primary SCC of the tongue on the opposite (right) side was detected in 2020. The patient did not agree to surgical treatment; therefore, radiotherapy was performed. The local recurrence of the tongue cancer of the right side was treated surgically in 2021. Salvage surgery comprised hemiglossectomy and dpFAMM flap reconstruction with uneventful postoperative follow-up. CONCLUSIONS: This case presentation proved that dpFAMM flap can be used in salvage surgery and reconstruction even in patients after ligation of facial vessels, irradiation, and in the course of hormone therapy. The flap is easy to handle, has good vascularity, and comprises a predictable method of reconstruction, especially for patients with severe comorbidities.

RESUMO

Basaloid squamous cell carcinoma (BSCC) in the head and neck area is extremely rare. World Health Organization defined BSCC as a high-grade variant of squamous cell carcinoma composed both of basaloid and squamous components. Due to its histologic similarity to other parotid gland malignancies it can be easily misdiagnosed. We report first case of BSCC arising from parotid gland in Europe and second in the world literature. A 72-year-old female patient was referred to the Department of Cranio-Maxillofacial Surgery of the Jagiellonian University in Poland due to the tumor arising from the right parotid gland. Patient had history of multiple excisions of recurrent basal cell carcinoma (BCC) of the left periorbital region. We performed total parotidectomy with facial nerve preservation. Postoperative radiotherapy (PORT) was carried out, and the patient received 70 Gy in 30 fractions on the parotid gland area due to the fact that the tumor adhered to the facial nerve trunk and branches, additionally 60 Gy on the neck area in I, II and III levels. To distinguish the tumor of the parotid gland from the possible metastasis from BCC of the left medial canthal region previous histopathological slides were also reexamined and compared with histopathological examination of removed parotid gland tumor. Histological examination confirmed a rare case of BSCC arising from the parotid gland. 14 months of the follow up did not show local recurrence or distant metastasis.

RESUMO

The aim of the retrospective analysis of the medical documentation of 101 patients was to assess the incidence, etiology, and type of craniofacial fractures in the elderly population of southern Poland, who required specialist treatment at the Department of Cranio-Maxillo-Facial Surgery Jagiellonian University, Krakow, Poland, in the period 2010-2019. Patients were divided into 3 age groups: 65-74, 75-84, and 85 and older. The following was noted: age, sex, place of residence, education, cause and location of fracture, treatment, injuries and comorbidities, complications, alcohol and other drugs at the time of injury, and the period of hospitalization. The dominant group were patients aged 65-74 (72.28%), mainly males (56.44%). The main cause was fall (47.52%). The fractures involved mainly the mandible and the zygomaticomaxillary complex. Over half of patients (50.50%) lived in the countryside or small towns. Work tool-related accidents prevailed among geriatric patients living in small towns and rural areas. Craniofacial fractures were additionally accompanied by common complications regarding the organ of vision. Further studies analyzing factors leading to increased risk of craniofacial injuries in the elderly of the rural population will enable proper support programs, prophylaxis, and principles concerning agricultural activities.

RESUMO

Background and Objectives: Ankyloglossia is a functional term describing limitations of motor activity of the tongue due to the embryological malformation of the lingual frenulum. The lingual frenulum has a complex, three-dimensional structure, it is not only a mucosal fold, which connects the ventral surface of the tongue and the floor of the mouth. Such knowledge forced us to develop more advanced techniques for tongue release in ankyloglossia. The aim of this study is to describe a novel, precise surgical technique for tongue release. Materials and Methods: Miofrenuloplasty was performed in six patients with impaired tongue movements due to anatomical limitations. All of them were prepared for surgery and evaluated after the procedure by a speech therapist. Results: The healing process was uneventful in all patients. We did not observe any major complications. Tongue mobility and neck muscle tension improved significantly in all cases. In one case, the speech improvement was minor. Conclusions: Miofrenuloplasty is an advanced, but effective and highly predictable procedure for full functional tongue release in cases caused by MFGG complex. It should be done by experienced surgeon.

RESUMO

Backgroundand Objectives: The reconstruction of tongue defects after cancer resection is challenging for reconstructive surgeons. The facial artery musculomucosal (FAMM) flap and the myomucosal buccinator flap (Bozola flap) are important tools in the reconstruction of intraoral defects. In this study, we describe the combination of both flaps-the extended, double-pedicled FAMM (dpFAMM) flap-and present clinical results of the reconstruction of moderate tongue defects in edentulous patients. Materials and Methods: a tongue defect, after squamous cell carcinoma excision, was reconstructed with the dpFAMM flap in 5 patients. Most of them received postoperative radiotherapy. Results: the healing process was uneventful in all patients. We did not observe flap necrosis or venous congestion. Tongue mobility, speech and swallowing were satisfactory. Conclusions: In conclusion, the dpFAMM flap is a good alternative in the reconstruction of moderate defects of the lateral part of the tongue. The flap is easy to harvest and has a good vascularity. This is a predictable method of reconstruction, especially for elderly patients with numerous comorbidities.

RESUMO

INTRODUCTION: Due to a relatively high recurrence rate of facial basal cell carcinoma (BCC), its morbidity is very significant. AIM: To analyse the expression of α-SMA, E-cadherin, Ber-Ep4 and MOC-31 as predictors of local recurrence in a group of patients with primary and recurrent BCCs of the face in correlation with histological and clinical data. MATERIAL AND METHODS: The study cohort included 79 patients with facial BCC (52 with primary BCC and 27 with recurrent BCC) who were treated at the Department of Cranio-Maxillofacial Surgery of the Jagiellonian University, Krakow in 1997-2009. RESULTS: Significant risk factors for local recurrence included: recurrent tumour (p = 0.001), multifocal BCC (p = 0.01), incomplete tumour excision (p = 0.02) and the aggressive infiltrating histologic subtype of BCC (p = 0.05). In the group of primary BCCs, positive expression of stromal α-SMA (p = 0.03) correlated with a statistically significant higher recurrence rate and so did positive expression of α-SMA in tumour cells of recurrent BCC (p = 0.002). In the group of primary aggressive BCC subtypes, reduced expression of MOC-31 was also associated with a higher rate of relapse (p = 0.02). CONCLUSIONS: Our findings provide information about α-SMA and MOC-31 expression in primary and recurrent BCCs. These data may contribute to the formulation of a more targeted treatment plan and follow-up strategy for patients with facial basal cell carcinoma.

RESUMO

Turban tumor syndrome (TTS) is a rare condition characterized by predisposition to developing multiple adnexal tumors. It is the rare autosomal dominant genodermatosis that is associated with the mutation of the CYLD suppressor gene. We herein report rare TTS in an adult who suffered from numerous episodic ulcerations of the scalp tumors and frequent bleeding following a minor trauma. The plain radiograms of the skull excluded bone marrow infiltration, and no regional lymphadenopathy was noted. The patient underwent total scalp excision and split skin grafting under general anesthesia in a single-stage operation. Recovery was uneventful. No recurrence was observed during the 2-year follow-up. Due to a high recurrence rate and risk of neoplastic transformation, surgery should be considered as the gold standard.

RESUMO

(1) Background: Epidemiological studies of epithelial salivary gland neoplasms are difficult to conduct effectively due to tumor rarity, histological heterogeneity, tumor location diversity, and a lack of national registries collecting data. This study presents 26 years of epidemiological data from a single institution in southern Poland that estimates incidence rates of primary epithelial salivary gland tumors. (2) Methods: The charts of 805 patients with epithelial salivary gland tumors were retrospectively reviewed. (3) Results: Pleomorphic adenomas occurred less frequently in elderly patients; however, Warthin tumors were more common (p < 0.001). Pediatric patients mainly suffered from mucoepidermoid carcinoma. The estimated crude and European age-standardized incidence rates of all primary epithelial salivary gland tumors were 6.7 and 6.02 per 100,000 population, respectively. The incidence rates of salivary gland tumors increased in recent years; however, this is attributed to an increase in benign tumors (p < 0.001). (4) Conclusions: The incidence of primary epithelial salivary gland tumors in southern Poland has increased over the past 26 years. This increase is attributed to a rise in the number of patients with benign tumors, particularly Warthin tumors in elderly patients. Moreover, the incidence of malignant salivary gland tumors appears to be higher in pediatric patients.

RESUMO

BACKGROUND: Extractions of third molars constitute about 90% of the scheduled surgical procedures performed by oral surgeons. Wisdom tooth surgery is associated with complications, such as the lingual and inferior alveolar nerve damage, bleeding, tooth/jaw fractures, tooth displacement into the adjacent anatomical spaces, trismus, infections, and other. OBJECTIVES: The aim of the study was to analyze complications after wisdom tooth extraction in patients treated at the Department of Oral Surgery of Jagiellonian University Medical College in Kraków, Poland, in the years 2016-2018. MATERIAL AND METHODS: A retrospective analysis of the medical records of 339 patients treated in the outpatient setting was performed. The inclusion criterion comprised a single extraction of a third molar. The exclusion criteria were multiple extractions, comorbidities and pregnancy. No antibiotic prophylaxis was used. The incidence of post-extraction complications, such as oroantral communication, postoperative hematoma, acute inflammation of the surrounding tissues, trismus, and transient paresthesia in relation to patient gender and age, the developmental stage and location of the removed tooth as well as the type of surgery were studied. RESULTS: Perioperative complications occurred in 51 (15.0%) cases, and comprised the acute inflammation of the surrounding tissues in 31 patients, trismus after the removal of 13 lower third molars, oroantral communication after the extraction of 5 upper wisdom teeth, and hematoma as well as a transient sensory alteration of the lingual nerve in 1 case each. Complications were more common in patients who had a surgical extraction of a wisdom tooth with root separation and in cases of lower third molar extractions. No statistically significant correlation was found between the patients' age or gender, the developmental stage of the extracted tooth and the number of observed complications. CONCLUSIONS: Lower third molars and the necessity of surgical extraction with root separation are risk factors for postoperative complications in patients who require wisdom tooth removal. Complications after the removal of third molars are most often inflammatory.

RESUMO

INTRODUCTION: The aim of periocular basal cell carcinoma (BCC) surgery is radical excision of the tumour while maintaining eyelid functionality and facial aesthetics. Differences in management of the patients after excision of eyelid BCC with a narrow margin are described in the literature. AIM: This study concerns the correlation between the recurrence rate in the periorbital area and the narrow safety margin of excision in the histopathological report with respect to various clinical and histopathological features. MATERIAL AND METHODS: A retrospective non-randomized analysis was conducted on 158 patients with BCC of the periorbital area. These patients were operated on between January 2002 and December 2016. A database was created, comprised of patient age, sex, location of the lesion, TNM, method of reconstruction, result of the histopathological examination, date and location of the recurrence. RESULTS: In 66 (41.77%) patients BCC was radically removed. In 50 (31.65%) patients BCC was removed with a narrow margin and in 42 (26.58%) cases, radical excision was not achieved. The recurrence rate was significantly higher in the aggressive BCC group compared to those with non-aggressive BCC (p = 0.004). The recurrence-free rate for non-aggressive subtypes was 98.11% in both the first and fifth years, but in aggressive subtypes it was 89.06% in the first year but fell to 80.16% in the fifth year. CONCLUSIONS: An aggressive subtype of BCC significantly influences the risk of non-radical excision of the lesion. Aggressive BCC subtypes should have more frequent check-ups. There is no need to reoperate patients with a narrow margin of BCC excision.

RESUMO

IgG4-related disease (IgG4-RD) is a rare immune-mediated condition characterized by extensive tissue fibrosis and infiltration by immunoglobulin G4 positive plasma cells in a single organ or systemic appearance. Two cases are presented including an unusual case of a 30-year-old man with IgG4-RD appearing simultaneously in the cervical lymph nodes, ethmoid, maxillary sinuses, and upper gingiva, with spontaneous loss of teeth. According to the literature, this is the first case with loss of teeth occurring in the course of the disease. The second case is a 46-year-old man suffering from IgG4-related chronic sclerosing sialadenitis of the right submandibular gland.

RESUMO

BACKGROUND: The purpose of this study was to evaluate the clinical usefulness of the immunoexpression of Ki-67, matrix metalloproteinase (MMP)-2, MMP-9, vascular endothelial growth factor (VEGF)-C, and VEGF-D in predicting follow-up treatment in patients with squamous cell carcinoma (SCC) of the tongue and floor of the mouth (FOM). METHODS: Marker expression was evaluated in surgical specimens taken from 60 patients who underwent surgery because of primary SCC without prior therapy. RESULTS: Strong MMP-2 expression was positively correlated with a higher risk of nodal recurrence (p = .047). Strong VEGF-C expression was found in patients with distant metastases (p = .008). Cox's regression model showed high Ki-67, MMP-2, and VEGF-C expression, which were independent predictors of disease-specific survival (p = .001, p = .002, and p < .001, respectively). CONCLUSION: It seems that targeting MMP-2 and VEGF-C may improve local control, thereby reducing the risk of distant metastasis in patients with SCC of the tongue and FOM. © 2015 Wiley Periodicals, Inc.

RESUMO

UNLABELLED: Blow-out fracture of the floor of the orbit is an increasingly recognized trauma. It may be an isolated injury, but because of various mechanisms may be also accompanied by the damage of other components of the visual system. The triad of clinical symptoms in blow-out fracture of the orbital floor includes: double vision, the enopthalmos and impaired sensation in the area of infraorbital nerve. Change of the position of the eyeball may lead to displacement and stretching of the optic nerve, which may result in the traumatic optic neuropathy. The aim of this paper is the evaluation of effectiveness of surgical and conservative tactics in the treatment of blow-out fracture of the floor of the orbit, accompanied by intraocular injuries, on the basis of retrospective study of the patients treated from 1971 to 2014. MATERIAL AND METHODS: Based on a retrospective analysis of medical records of a group of 752 patients treated in our Department due to blow-out fracture of the orbit, during 44 years (1971-2015), intrabulbar injuries were found in 98 (13%) patients, and decrease in visual acuity was observed in 84 (11.2%) patients. In patients with decreased visual acuity values of sight acuity ranged from light perception to 0.8, in 3 patients the blow-out fracture of the orbit was accompanied by the superior orbital fissure syndrome, while in four patients orbital apex syndrome was observed. Statistical analysis of parameters of sight acuity before and after treatment was performed. The Wilcoxon test was used for dependent measurements (repeated), visual acuity after treatment was significantly higher than before. Due to the complexity of the injury, treatment of orbital floor fracture requires a multidisciplinary approach, in the team of maxillofacial surgeon, ophthalmologist, radiologist and neurologist.

RESUMO

The aim of the research was to es timate the efficiency of the computed tomography (CT) in diagnosing meta stasis of submandibular and submen tal lymph nodes (level 1) in patients with diagnosed lower lip cancer. CT of neck lymph nodes was con ducted in 31 patients with diagnosed lower lip cancer. The total of 136 lymph nodes were identified, of which 16 were diagnosed as metastatic in histopathological examination. T investigated parameters were: shape, size (longitudinal and axial diameter and the surface of the cross-sections), presence of the fatty hilus, and level of enhancement after introvascular contrast agent administration. Correlation between the level of enhancement in the primary tumor and the enhancement in the metastatic lymph nodes was observed; density values before and after the admini stration of the contrast agent were in both cases at a similar level. It was also found that the best criterion in the diagnosis of metastatic lymph nodes is the minimal axial diameter: for this parameter, the highest accuracy (74%) was observed for the value of 6 mm. As for the surface of the cross-sections of the lymph node, it was found that the best criterion is the axial cross-section surface: the accuracy of 74% was ob tained for the surface of 38mm2.

RESUMO

Primary intraosseous squamous cell carcinoma (PIOSCC) is a rarely reported neoplasm resulting from malignant transformation of a dentigerous cyst of the mandible or maxilla. Until 2010, only 116 cases had been described. The diagnosis of PIOSCC is difficult because of non-specific symptoms. A case of a 66-year-old patient with PIOSCC arising from a dentigerous cyst of the mandible is presented. Both pathologists and clinicians should be aware of the probability of malignant transformation of dentigerous cysts during the two-stage treatment. The patient should be subject to regular clinical and radiographic examination.
