ABSTRACT
INTRODUCTION: The presence of cervical lymph node metastases is an unfavorable prognostic factor in head and neck squamous cell carcinoma (HNSCC) and a potential cause of treatment failure. Occult lymph node metastasis occurs in approximately 15-20% of HNSCC patients with a clinically negative neck (cN0), greatly impacting on their prognosis. The present study aimed to investigate the role of pre-treatment peripheral blood markers in predicting clinically occult cervical lymph node metastasis. METHODS: This multicenter, retrospective study was performed in a cohort of 472 patients diagnosed with cN0 HNSCC who underwent up-front surgery. Baseline neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), lymphocyte-to-monocyte ratio (LMR), systemic inflammatory marker (SIM), and systemic immune-inflammation index (SII) were calculated from available blood parameters. RESULTS: Oro-hypopharyngeal and oral cancers, locally advanced stage, moderately (G2), and poorly (G3) differentiated grade were associated with an increased risk of pathological lymph node involvement. NLR, LMR, PLR, SIM, and SII were significantly associated at multivariable analysis. NLR >2.12 was the most reliable at predicting occult lymph node metastasis (OR = 5.22; 95% CI: 2.14-12.75). We describe a predictive score integrating cancer site, local stage, and NLR which is effective at predicting positive lymph node pathological status. CONCLUSIONS: The present study provides evidence that pre-treatment peripheral blood markers, in particular NLR, represent reliable predictors of clinically occult cervical lymph node metastasis in cN0 HNSCC. Therefore, the present study provides a novel useful predictive score for directing the elective management of the neck in patients with cN0 HNSCC.

PURPOSE: Acquired Chiari I malformation is an uncommon but possible late complication of supratentorial shunting in children. This condition can be caused by an abnormal thickening of the cranial vault and consequent reduction of the posterior cranial fossa (PCF) volume especially in children with already a small PCF volume. The management of Acquired Chiari I malformation is very challenging, and several options have been proposed for this condition. These are aimed to expand the PCF volume both through decompression and PCF remodeling in order to relieve symptoms of acquired Chiari I malformation. A cranial vault remodeling or a standard Chiari decompression is two proposed techniques aimed to expand the PCF volume thus relieving symptoms . METHODS: We describe the case of a 16-year-old girl undergone surgical removal of sellar-suprasellar glioneuronal tumor and ventriculo-peritoneal shunting, who developed an acquired symptomatic Chiari type I malformation some years after ventricular-peritoneal shunting. For this condition, she underwent successful standard Chiari decompression with C0-C1 craniectomy and duroplasty. RESULTS: We retrospectively analyzed MRI and CT scan performed during follow-up, in order to evaluate the volume of the posterior cranial fossa and to measure the variation of skull thickness at different periods. MRI and CT scan analysis showed a progressive thickening of the calvaria, in particular of the occipital bone, leading to a progressive reduction of PCF volume with the establishment of acquired Chiari type I malformation. In this case, standard C0-C1 Chiari decompression was effective in restoring PCF volume and relieving symptoms. CONCLUSION: Acquired Chiari I malformation due to chronic overhunting could be a severe and late complication in patient undergone supratentorial shunting. These patients require careful clinical and radiological follow-up to avoid over-drainage. According to our analysis, a careful selection of pediatric patients for supratentorial shunting should be made according to pre-operative PCF volume in order to foresee higher odds of possible late complications from over-drainage.

BACKGROUND/OBJECTIVE: The aim of this study was to assess the impact of sinonasal morbidity on quality of life (QoL) in antineutrophil cytoplasmic antibody-associated vasculitis (AAV). METHODS: This cross-sectional case-control study enrolled 71 patients-44 AAV cases with (ear, nose, and throat [ENT]-AAV) or without ENT involvement (non-ENT-AAV) undergoing multidisciplinary evaluations and 27 chronic rhinosinusitis (CRS) cases. Three validated QoL questionnaires (Sino-Nasal Outcomes Test-22 [SNOT-22], Nasal Obstruction Symptom Evaluation [NOSE], and Short-Form 36) were administered, and the 3 groups were compared. RESULTS: The ENT-AAV patients were significantly younger (p = 0.01), with less antineutrophil cytoplasmic antibody positivity frequency (p = 0.035) and lower renal involvement (p = 0.003) than the non-ENT-AAV patients.The SNOT-22 questionnaire demonstrated significantly greater sinonasal morbidity in ENT-AAV patients compared with CRS patients (p < 0.001). The NOSE score of ENT-AAV patients was comparable to those of CRS patients, but higher than that of non-ENT-AAV patients (p < 0.001). The SNOT-22 and NOSE scores positively correlated with disease activity (p = 0.037; p = 0.004, respectively). Short-Form 36 domain-by-domain analysis revealed a significantly poorer QoL in ENT-AAV patients, especially with physical functioning being progressively impaired in CRS, non-ENT-AAV, and ENT-AAV patients (p < 0.001). No significant differences in QoL came to light when AAV patients were stratified according to current systemic o local treatments. CONCLUSIONS: The QoL in AAV patients is significantly reduced, especially in the presence of ENT involvement. The AAV-related nasal morbidity is consistent and comparable to that reported by CRS patients. It significantly affects patients' QoL and in particular social functioning, leading to limitation in daily/work activities. Organ-focused questionnaires and multidisciplinary management are warranted to pursue a treat-to-target approach in these patients.

INTRODUCTION: Paediatric tumours in the sellar and parasellar regions present clinical and surgical challenges due to anatomical position and behaviour. We illustrate a rare case which caused obstructive hydrocephalus. CASE PRESENTATION: The study included a 14-year-old girl with a glioneuronal tumour (40 mm) originating from the optic chiasm, obliterating the aqueduct, with consequent triventricular hydrocephalus. The patient underwent extended endoscopic endonasal surgery and repair of the skull-base deficiency using a multi-layer technique with fascia lata. The 12-month follow-up showed no complications or recurrences, with recovery in visual acuity. CONCLUSION: The immediate placement of external ventricular drainage, in combination with an extended trans-sphenoidal approach, is a safe and feasible option to treat suprasellar paediatric lesions with hydrocephalus.

BACKGROUND: To evaluate the impact of endoscopic sinus surgery (ESS) on clinical outcomes, quality of life (QoL) and Nasal Obstruction and Symptom Evaluation (NOSE) scale in patients with CRSwNP and CRSsNP. An additional question that needs to be investigated is whether there is a correlation between patients at the age of relapse. METHODOLOGY/PRINCIPAL: A prospective cohort study of 150 subjects [96 males, 54 females, mean age: 51.99 ± (15.73)]. The SNOT-22 and NOSE questionnaires were used to measure the patients' QoL and their nasal blockage symptoms, respectively. Endoscopic and computerized tomography (CT) scores depicted the objective findings. RESULTS: Following ESS, the endoscopic scale showed a significant improvement in 83.85% of patients. QoL measured with SNOT-22 improved by 78.85% and with NOSE scale by 92.10%. Also, a statistically significant correlation was found between NOSE, SNOT-22 and the Lund-Kennedy scale. Recurrence was observed in 13 patients during follow-up. There was no statistically significant correlation between age, gender, smoking and recurrence tendency. Patients with baseline SNOT-22 and NOSE scores lower than 30 typically fail to obtain a clinically meaningful benefit. Patients with a rate greater than or equal to 40 achieved a minimal clinically important difference (MCID) of 83.9% and had an average symptom reduction (RI) rate of 60.3%. CONCLUSIONS: ESS is an important treatment option for symptomatic patients with CRSwNP and CRSsNP. Both objective and subjective measurements including QoL improved significantly, and the results stabilized at 12 to 18 months. The NOSE scale is a sensitive outcome measure in the CRS population, including subjects with and without nasal polyps. In our study, SNOT-22 and NOSE are excellent predictors of postoperative improvement.

BACKGROUND: Retropharyngeal and parapharyngeal abscesses (RPAs, PPAs) usually affect young children. Surgical drainage and/or antibiotic therapy are treatment of choice, but no specific guidelines exist. In order to reduce the risk of severe complications, appropriate diagnosis and therapy are necessary. The aims of the study were to review diagnosis and management of children with RPAs/PPAs and to compare surgical versus medical approach. METHODS: This is a multicenter retrospective study including all patients younger than 15 years admitted at 4 Italian pediatric hospitals of Florence, Padua, Rome, and Treviso, with International Classification of Diseases, Ninth Revision discharge diagnosis code of RPAs and PPAs, from January 1, 2008, to December 31, 2016. RESULTS: One hundred fifty-three children were included. The median age was 4.4 years, with overall male predominance. Heterogeneous signs and symptoms (fever, neck cervical, lymphadenopathy, pain, and stiff neck most frequently) and a large mixture of bacteria from pus cultures were detected. Computer tomography (66.7%) and magnetic resonance imaging (27.5%) were performed to confirm the presence of abscess. Fifty-one percent of abscesses were greater than 3 cm. Eighty-seven patients (56.9%) underwent surgery, and 66 (43.1%) were treated with antibiotics alone (mostly ceftriaxone, metronidazole, amikacin, and clindamycin) with median days of therapy of 26.5 days and length of therapy of 16.0 days of median. Median length of stay was 11 days. None had severe complications. Multivariate analysis indicated as independent predictive factors of surgery abscess of 3 cm or greater, high white blood cell count, and-most of all-the hospital of admission. CONCLUSIONS: Deep neck abscesses mostly affect patients in early childhood, with a combination of nonspecific signs and symptoms, and it still emerges as a heterogeneous approach in diagnosis and management of these infections. Thus, common shared protocols represent an essential tool in order to standardize care and improve patients' outcomes.

Secreting pituitary adenomas are tumors for which few treatment options are available, including surgical treatment and management of hormonal imbalance due to altered pituitary secretion. In case of inoperable relapse, radiotherapy or chemotherapeutic treatment can be considered; the effectiveness of these treatments, however, remains limited. In the immunotherapy era, it is necessary to select patients who can benefit from immunotherapeutic treatment. Mismatch repair deficiency is strongly associated with responsiveness to anti-PD-1 in other cancers and can be detected using immunohistochemistry for MLH1, MSH2, MHS6, and PMS2. In this case report, we report a case of rapid disease progression to pembrolizumab in a patient with a MMRd pituitary adrenocorticotropic hormone (ACTH)-secreting adenoma. For the best of our knowledge, we described for the first time, a poor efficacy of pembrolizumab in a patient with ACTH-secreting pituitary adenoma having mismatch repair deficiency probably caused by high levels of cortisol in this patient. Prospective study should be performed to assess the activity of immune checkpoint inhibitor alone or in association with temozolomide in this subsetting of pituitary adenomas.

ABSTRACT
PURPOSE: Spontaneous skull base cerebrospinal fluid leaks occurring without any apparent cause are rare. But those patients that present such leaks simultaneously, or successively, in multiple locations are even rarer. Given the rarity of this condition, we collected data from other groups in a multicentre study to reach an adequate number of patients and draw some preliminary considerations. METHODS: We carried out a multicentre retrospective study on a cohort of patients treated at third level hospitals in Italy, Spain, United Kingdom and Greece for multiple spontaneous-CSF leaks and we compared them with a control group of patients treated for recurrent spontaneous-CSF leaks. Data regarding clinical aspects, radiological findings, surgical techniques and outcome were collected and preliminary considerations on the results were discussed. RESULTS: A total of 25 patients presented multiple simultaneous spontaneous CSF leaks while 18 patients fit with the criteria of recurrent spontaneous CSF leaks. Data analysis was conducted separately. CONCLUSIONS: Our understanding of the pathogenesis of this condition is currently very limited. A causative role of IIH may be present but the differences that emerged from the comparison with patients with recurrent fistulas seem to promote the possible role of other cofactors. A longer follow-up period is needed, and, in our opinion, prospective and multicentre studies are the only solution to seriously deal with such a complex topic.

BACKGROUND: Maxillary fungus ball (FB) is the most frequent paranasal localization. OBJECTIVE: To review clinical presentation, surgery and results of treatment in our series of patients with maxillary FB. To review the literature concerning treatment of maxillary FB. PATIENTS AND METHODS: 48 patients with a diagnosis of maxillary FB were treated with endoscopic sinus surgery (ESS) alone or in association with external approaches. Before surgery all patients received computed tomography (CT), nasal endoscopy and dental examination. All the patients were followed for 1â¯year after surgery. Studies concerning surgical treatment of maxillary FB from 2006 were reviewed. RESULTS: The mean age of patients was 53.6⯱â¯11.9â¯years. 20 patients (41.6%) did not present any symptom, 19 patients (39.7%) had nasal symptoms, 3 patients (6.2%) had facial pain, 6 patients (12.5%) had a combination of both. Endoscopic examination was positive in 31 patients (64.6%), 17 patients (35.4%) showed negative findings. Logit regression model demonstrated that clinical symptoms contribute to the prediction of a positive endoscopic examination. 25 patients (52.1%) presented odontogenic factors. Complete clinical and radiological resolution of FB was observed in 46 patients (95.8%). CONCLUSIONS: Comparing our sample to the studies reviewed we may concluded that odontogenic factors were frequently reported and should be treated at the same time of maxillary FB. ESS alone or in association with external approaches is an effective treatment for patients with maxillary FB.

BACKGROUND: Pituitary adenomas are usually considered benign tumours, although some of them can exhibit an aggressive behaviour. Patients with clinically aggressive pituitary adenomas are frequently diagnosed with larger masses, and may present an earlier recurrence (or persistence) after surgery. Our aim was to characterise the clinical, histopathological and radiological features of patients with aggressive pituitary adenoma, in order to correlate their clinical behaviour with the response to treatment plan. METHOD: We considered an aggressive pituitary adenoma on the basis of radiological features (size, local invasion), pathological reports (atypical adenoma: MIB-1 >3%, p53 immunoreactivity, increased mitotic activity) and clinical aspects (response to surgery, radiotherapy and medical treatment). RESULTS: Among our cohort of 582 patients, we considered 102 subjects with aggressive pituitary adenomas (18%, 56 male and 46 female): 14 adrenocorticotrophic hormone (ACTH)-secreting, 18 growth hormone (GH)-secreting, 23 prolactin (PRL)-secreting and 47 non-secreting, with a median follow-up of 5 years. In the whole cohort, 75% of patients with aggressive pituitary adenomas presented invasion of surrounding structure, especially GH-secreting, PRL-secreting and non-secreting. Besides invasion, their remission rate after surgery, radiotherapy or medical treatment was similar, irrespective of hormonal secretion. Surgery was the most performed treatment (overall remission rate of 24%), especially in those patients with ACTH- or GH-secreting adenoma, and 22% of patients were submitted to radiotherapy, with a remission rate of 45% after a median of 3 years. Two consecutive years of medical treatment, in patients with secreting pituitary adenoma, achieved disease control in 41% of them. Considering pathological reports, 24% of cases were defined as atypical adenomas; radiological characteristics, responses to medical treatment and remission rates were similar among patients with typical and atypical adenoma. CONCLUSIONS: We proposed a new and comprehensive definition of aggressive pituitary adenoma, based upon radiological, clinical and pathological features. In a selected cohort of patients, radiological invasion resulted in the most common marker to describe the aggressive behaviour of pituitary adenoma. Surgery, radiotherapy and medical treatment (the latter only in secreting adenoma) achieved disease control in half of the patients with aggressive adenoma, especially surgery in those with ACTH-oma and medical treatment in those with GH- and PRL-secreting adenoma. Nevertheless, radiological, clinical or atypical features did not affect the outcome.

PURPOSE: Most primary tumors spreading metastasis to the parotid gland are usually located in the head and neck region, nonetheless, rarely, parotid gland can also be the target of metastatic localization site of distant primary tumors. The purpose of this study was to describe a clinical series of metastasis to the parotid gland from distant primary tumors (non Head & Neck). METHODS: The clinical databases of parotid tumors in two academic centers have been analyzed and 11 cases of parotid metastatic cancers from distant primary tumors were found. RESULTS: Primary tumor was lung cancer in 8 cases, and breast cancer, gastric carcinoma and pancreatic carcinoma in one case each. CONCLUSIONS: Parotid metastases can be the first clinical manifestation of a malignant tumor from a distant site and can manifest years after curative-intent treatment of the distant primary. Histopathology and immunohistochemistry can help in the identification of the primary site. Parotidectomy with complete excision of the parotid lesion may have diagnostic and/or loco-regional control and/or curative intent, however there is still no international consensus about the therapy of parotid malignant metastasis.

The maxillary sinus is the most common site of sinonasal inverted papilloma. Endoscopic sinus surgery, in particular endoscopic medial maxillectomy, is currently the gold standard for treatment of maxillary sinus papilloma. Although a common technique, complications such as stenosis of the lacrimal pathway and consequent development of epiphora are still possible. To avoid these problems, we propose a modification of this surgical technique that preserves the head of the inferior turbinate and the nasolacrimal duct. A retrospective analysis was performed on patients treated for maxillary inverted papilloma in three tertiary medical centres between 2006 and 2014. Pedicle-oriented endoscopic surgery principles were applied and, in select cases where the tumour pedicle was located on the anterior wall, a modified endoscopic medial maxillectomy was carried out as described in this paper. From 2006 to 2014 a total of 84 patients were treated. A standard endoscopic medial maxillectomy was performed in 55 patients (65.4%), while the remaining 29 (34.6%) had a modified technique performed. Three recurrences (3/84; 3.6%) were observed after a minimum follow-up of 24 months. A new surgical approach for select cases of maxillary sinus inverted papilloma is proposed in this paper. In this technique, the endoscopic medial maxillectomy was performed while preserving the head of the inferior turbinate and the nasolacrimal duct ("TuNa-saving"). This technique allowed for good visualization of the maxillary sinus, good oncological control and a reduction in the rate of complications.

BACKGROUND: Occupational exposure to chromium is carcinogenic for human respiratory system. Due to the low incidence of sinonasal malignancies, there is still a paucity of evidence to confirm that chromium(VI) exposure is a cause of nasal cancer. OBJECTIVES: To report on a sinonasal cancer (SNC) of rare occupational origin, increasing the awareness on epidemiological knowledge of occupational exposures to chromium compounds. METHODS: We describe a case of a 64-year-old chrome plater who worked in the galvanic industry in the early 1970s. After a latency period of 39 years, he was diagnosed with sinonasal undifferentiated carcinoma (SNUC). A brief review of the literature was conducted. RESULTS: A thorough occupational history revealed a 4-year-long occupational exposure to chromium(VI) during a magnesium cylinder plating process involved in computer production. The patient underwent endoscopic endonasal removal of the SNUC. He is alive with no evidence of disease at 40-month follow-up. Our literature review identified 8 papers concerning 40 cases of chrome-induced sinonasal tumors. The maximum relative risk of SNC developing in chromium-exposed workers was 15.4. CONCLUSIONS: When dealing with patients diagnosed with SNC, the possibility of an underlying occupational risk is worth further investigation. Because chromium exposure is rare, and the incidence of SNUC is low, any information emerging on clinical and exposure-related aspects of SNCs in chrome plating workers can contribute to adding evidence on the possible causal relationship between chromium and sinonasal malignancies.

Aggressive pituitary adenomas (PAs) are clinically challenging for endocrinologists and neurosurgeons due to their locally invasive nature and resistance to standard treatment (surgery, medical or radiotherapy). Two pituitary-directed drugs have recently been proposed: temozolomide (TMZ) for aggressive PA, and pasireotide for ACTH-secreting PA. We describe the experience of our multidisciplinary team of endocrinologists, neurosurgeons, neuroradiologists, oncologists, otolaryngologists and pathologists with TMZ and pasireotide treatment for aggressive PAs in terms of their radiological shrinkage and genetic features. We considered five patients with aggressive PA, three of them non-secreting (two ACTH-silent and one becoming ACTH secreting), and two secreting (one GH and one ACTH). TMZ was administrated orally at 150-200 mg/m(2) daily for 5 days every 28 days to all 5 patients, and 2 of them also received pasireotide 600-900 µg bid sc. We assessed the MRI at the baseline and during TMZ or pasireotide treatment. We also checked for MGMT promoter methylation and IDH, BRAF and kRAS mutations. Considering TMZ, two patients showed PA progression, one stable disease and two achieved radiological and clinical response. Pasireotide was effective in reducing hypercortisolism and mass volume, combined with TMZ in one case. Both treatments were generally well tolerated; one patient developed a grade 2 TMZ-induced thrombocytopenia. None of patients developed hypopituitarism while taking TMZ or pasireotide treatment. No genetic anomalies were identified in the adenoma tissue. TMZ and pasireotide may be important therapies for aggressive PA, alone or in combination.

BACKGROUND: The purpose of the present study was to evaluate long-term outcomes of endoscopic dacryocystorhinostomy (DCR) using a drill without the use of mucosal flaps. Ninety one procedures in eighty seven patients were reviewed. All patients showed epiphora, caused by primary or secondary nasolacrimal obstruction. METHODOLOGY: All patients underwent preoperative evaluation (irrigation and probing of the lacrimal drainage system, fluorescein tests, computerized tomography scan of the paranasal sinuses, dacryocystography and endoscopic examination of the nasal cavity). In 19 patients further intranasal procedures were conducted simultaneously with DCR (10 FESS, 2 septoplasties, 5 functional endoscopic sinus surgery (FESS) and septoplasties, 2 septoplasties and turbinoplasties). Stents were placed intraoperatively and removed 4 to 12 weeks, postoperatively. Postoperative follow-up ranged between 12 and 24 months. RESULTS: Long-term success was achieved in 87/91 procedures. No major complications were observed. Failure was caused by granulation tissue formation in three patients and inappropriate stent removal in one patient. CONCLUSION: The success rate achieved is comparable to success rates of external DCR.

One of the biggest challenges for otolaryngologists is represented by the locally recurrent undifferentiated nasopharyngeal carcinoma (uNPC). Despite improvements in its treatment options, such as modern radiotherapy, chemotherapy, or external surgical approaches, the risk for severe complications, functional disabilities, and even death remains considerable. Over the years, advances in endoscopic surgery have led to a new alternative in the salvage surgery for recurrent uNPC: the nasopharyngeal endoscopic resection (NER). We retrospectively reviewed clinical records of 8 patients (6 men and 2 women), who underwent NER for recurrent T1 (rT1) locally recurrent uNPC between 2008 and 2011. Together with resections for subsequent recurrences, a total of 9 NERs were performed by a single surgeon with curative intent. Negative margins were obtained for the whole group of patients. After a mean follow-up period of 27 months (range, 16-54 mo), all the patients had no evidence of the disease. We had only 1 recurrence after 7 months. Two-year overall survival and disease-free survival rates were 100% and 88.9%, respectively. Only 1 patient presented with a complication, osteitis. Nasopharyngeal endoscopic resection can be considered a valid and promising treatment option for rT1 locally recurrent uNPC, showing encouraging short-term outcomes and complication rate. Long-term follow-up is needed to state the efficacy of NER, together with a larger number of patients.

OBJECTIVE: Delayed facial nerve palsy (dFNP) secondary to head injury is definitely uncommon. Although the mechanism of immediate facial nerve paralysis is well-studied, its delayed presentation remains debated. Given the dearth of available information, we reported herein our experience with 2 cases of posttraumatic dFNP. This systematic review aimed to evaluate all available information on dFNP and to assess treatment outcome also comparing conservatively and surgically approaches. DATA SOURCES: Pubmed, Scopus, and Web of Science databases were systematically screened. REVIEW METHODS: The protocol of this investigation was registered on PROSPERO in April 2023 and the systematic review was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses statement. RESULTS: Both patients in the case studies showed a complete recovery within 2 to 3 months after the head trauma. One of them still reported a subjective taste alteration at last control. After the application of the inclusion-exclusion criteria, 9 manuscripts with adequate relevance to this topic were included in the systematic review. The study population consisted of 1971 patients with a diagnosis of posttraumatic facial nerve palsy, of which 128 with a dFNP. CONCLUSIONS: dFNP due to head trauma is a rarely encountered clinical entity, and optimal treatment still remains to be elucidated. Based on the reported data, it seems rational to propose a conservative approach for dFNP with steroid administration as a first line in most cases, indicating surgery in severe and/or refractory cases.
ABSTRACT
Sinonasal intestinal-type adenocarcinoma (ITAC) is a very rare, closely occupational-related tumor with strong histological similarities to colorectal cancer (CRC). In the latter, tumor budding (TB) is widely recognized as a negative prognostic parameter. The aim of this study was to evaluate the prognostic role of TB in ITAC and to correlate it with other established or emerging biomarkers of the disease, such as p53 and deficient DNA mismatch repair (MMR) system status/microsatellite instability (MSI). We retrospectively analyzed 32 consecutive specimens of patients with ITAC diagnosis treated in two institutions in Northern Italy. We reviewed surgical specimens for TB evaluation (low-intermediate/high); p53 expression and MMR proteins were evaluated via immunohistochemistry. Results were retrospectively stratified using clinical data and patients' outcomes. According to bud counts, patients were stratified into two groups: intermediate/high budding (>4 TB) and low budding (≤4 TB). Patients with high TB (>4) have an increased risk of recurrence and death compared to those with low TB, with a median survival of 13 and 54 months, respectively. On multivariate analysis, considering TB, therapy, and stage as covariates, TB emerged as an independent prognostic factor net of the stage of disease or type of therapy received. No impact of p53 status as a biomarker of prognosis was observed and no alterations regarding MMR proteins were identified. The results of the present work provide further significant evidence on the prognostic role of TB in ITAC and underline the need for larger multicenter studies to implement the use of TB in clinical practice.
ABSTRACT
OBJECTIVE: To evaluate the outcome of combined surgical treatment of oroantral communications associated with chronic maxillary sinusitis. PATIENTS AND METHODS: 8 consecutive patients affected by complicated oroantral fistula were included in the study. The protocol consisted of: clinical, endoscopic and radiological preoperative evaluation (panoramic tomogram and computed tomography); systemic antibiotic and steroid therapy 2 weeks before surgery; one-stage surgical procedure under local anaesthesia consisting in uncinectomy with enlargement of the osteomeatal complex through endoscopic nasal approach associated with the closure of the oroantral communication by means of a mucoperiosteal flap; postoperative antibiotic and cortisone-based therapy. Follow-up consisted of weekly clinical evaluation during the first month, and nasal endoscopy at 3, 8 and 24 weeks after surgery. RESULTS: After surgical treatment, all patients were symptom-free and had no endoscopic and radiological evidences of maxillary sinusitis at the 6-month follow-up. No recurrent oroantral fistulas were found. CONCLUSIONS: The current prospective study showed that a one-stage, combined endoscopic and intraoral approach under local anaesthesia represents a feasible and minimally invasive procedure for the long-term effective treatment of chronic complicated oroantral communications. Moreover, it represents an easily applicable approach also in outpatient clinics with minor patient discomfort.
