RESUMO
BACKGROUND: Adrenal cysts are rare and appropriate management is unclear due to a lack of data on their natural history. Understanding adrenal cyst growth patterns would assist in clinical management. METHODS: This single-institution study included all adult patients diagnosed with simple adrenal cysts between 2004 and 2021. Baseline characteristics and outcomes of those who underwent resection (ADX) or observation (OBS) were compared using the chi-squared test, student's t-test, and Wilcoxon rank-sum test. Growth curves and sensitivity analysis were plotted for all patients who had follow-up imaging. RESULTS: We identified 77 patients with imaging-confirmed adrenal cysts. The majority were female (75.3%) and more than half were white (55.8%). One-third of patients underwent ADX, and the remaining were observed. ADX patients were younger (median age [IQR]: 55.5 y [45.0-68.2 y] vs. 44.2 y [38.7-55.0 y], p = 0.01) and more likely to be Hispanic (12% vs. 0%, p = 0.05). ADX patients presented with larger cysts (5.6 vs. 2.6 cm, p = 0.002). The median time from diagnosis to last follow-up was 1.1 y for ADX and 4.1 y for OBS. Average growth for OBS was 0.3 cm/y, while average growth for ADX was 3.9 cm/y. In ADX patients, cysts >10 cm grew significantly faster than cysts <10 cm (median growth rate 13.2 cm/y vs. 0.3 cm/y, p < 0.05). There was no adrenal malignancy diagnosis, hyperfunctionality, or observation-related complications (e.g., rupture). CONCLUSION: While size >4-6 cm has guided surgical referral for solid adrenal masses, this study demonstrates a size threshold of 10 cm, below which asymptomatic, simple adrenal cysts can safely be observed.

PURPOSE: To analyze the clinicopathological characteristics and surgical outcomes of patients with Wolfring gland ductal cysts (WGDCs). METHODS: A retrospective, consecutive, interventional comparative case series was performed over a period of 7 years. Data on demographic and clinical characteristics, pathological findings and outcomes of surgically excised cysts were collected. A comparison between the transconjunctival and transcutaneous approaches was also assessed. RESULTS: Forty-eight patients (48 eyelids) were included in the final analysis. The most common presenting symptom was painless eyelid swelling (81.3%). The median symptom duration was 11.5 months (IQR, 18.25). The upper eyelid was involved in 31 (64.6%) patients, 29/31 of whom had cysts in a medial or centromedial location. Forty-five (93.8%) cysts were bluish gray and transilluminable with clear contents on lid eversion and a median largest dimension of 22 mm (IQR, 8). A transverse conjunctival fibrotic band was observed along the proximal tarsal border in the cyst area in all patients. Signs of chronic trachoma were noted in 38 (79.2%) patients. Preoperative significant ptosis was present in 28/31 (90.3%) of the upper eyelid cysts. Thirty cysts (62.5%) were excised through the skin, and 18 cysts (37.5%) were excised transconjunctivally. Intraoperative cyst rupture, the need for conjunctival grafting and postoperative residual upper lid ptosis were significantly greater in the transconjunctival group (p = 0.009, p < 0.001, and p = 0.016, respectively). CONCLUSION: The present study highlights the clinicopathological characteristics of a relatively large series of surgically excised WGDCs. Transcutaneous excision of WGDCs has proven to be an effective treatment with fewer adverse sequelae than the transconjunctival approach.

Cystic degeneration of the fibrous dysplasia is a very rare clinical condition and may present with loss of vision when it involved the skull base. A 12-year-old female child presented with an enlargement of the skull. She was diagnosed as large skull base and skull vault tumor. She underwent partial removal of the tumor, and custom-made titanium implant was inserted. The diagnosis was fibrous dysplasia. Two years after the initial diagnosis, she presented with total loss of vision at her right eye. Radiological imaging confirmed the cystic degeneration within the tumor. She re-operated and the cyst fluid was evacuated in association with the removal of cyst wall. The diagnosis was the cystic degeneration of the fibrous dysplasia. Her vision was improved a few days after the surgery. Fibrous dysplasia of the skull base should be closely followed-up in order to prevent severe visual complications.

This letter evaluates the recent study on the management of cystic vestibular schwannomas (VS) compared to solid VS, focusing on the clinical outcomes of surgery (SURGERY) and radiosurgery (SRS). The study offers significant insights into the differences between these tumor types, emphasizing the challenges posed by cystic VS, including rapid growth, enhanced peritumoral adhesion, and worse post-operative facial nerve outcomes. Notably, cystic VS are associated with higher recurrence rates and poorer preoperative status. The study also highlights lower gross total resection (GTR) rates and poorer long-term tumor control in cystic VS. While SRS shows high rates of functional preservation, it is less effective in ensuring recurrence-free survival in cystic VS compared to solid VS, suggesting surgery may be preferable for achieving the best long-term outcomes, particularly when safe maximal resection is possible. However, the study's retrospective design and limited sample size, along with the lack of standardized follow-up protocols, may impact the generalizability of the findings. Future research should focus on prospective, multicenter studies with standardized protocols to develop evidence-based guidelines for managing cystic VS. Innovative techniques, such as advanced imaging and minimally invasive surgical approaches, may further improve diagnostic accuracy and treatment efficacy. This study underscores the complexities of managing cystic VS and the need for tailored treatment strategies.

Some vestibular schwannoma (VS) show cystic morphology. It is known that these cystic VS bear different risk profiles compared to solid VS in surgical treatment. Still, there has not been a direct comparative study comparing both SRS and SURGERY effectiveness in cystic VS. This retrospective bi-center cohort study aims to analyze the management of cystic VS compared to solid VS in a dual center study with both microsurgery (SURGERY) and stereotactic radiosurgery (SRS). Cystic morphology was defined as presence of any T2-hyperintense and Gadolinium-contrast-negative cyst of any size in the pre-interventional MRI. A matched subgroup analysis was carried out by determining a subgroup of matched SURGERY-treated solid VS and SRS-treated solid VS. Functional status, and post-interventional tumor volume size was then compared. From 2005 to 2011, N = 901 patients with primary and solitary VS were treated in both study sites. Of these, 6% showed cystic morphology. The incidence of cystic VS increased with tumor size: 1.75% in Koos I, 4.07% in Koos II, 4.84% in Koos III, and the highest incidence with 15.43% in Koos IV. Shunt-Dependency was significantly more often in cystic VS compared to solid VS (p = 0.024) and patients with cystic VS presented with significantly worse Charlson Comorbidity Index (CCI) compared to solid VS (p < 0.001). The rate of GTR was 87% in cystic VS and therefore significantly lower, compared to 96% in solid VS (p = 0.037). The incidence of dynamic volume change (decrease and increase) after SRS was significantly more common in cystic VS compared to the matched solid VS (p = 0.042). The incidence of tumor progression with SRS in cystic VS was 25%. When comparing EOR in the SURGERY-treated cystic to solid VS, the rate for tumor recurrence was significantly lower in GTR with 4% compared to STR with 50% (p = 0.042). Tumor control in cystic VS is superior in SURGERY, when treated with a high extent of resection grade, compared to SRS. Therapeutic response of SRS was worse in cystic compared to solid VS. However, when cystic VS was treated surgically, the rate of GTR is lower compared to the overall, and solid VS cohort. The significantly higher number of patients with relevant post-operative facial palsy in cystic VS is accredited to the increased tumor size not its sole cystic morphology. Cystic VS should be surgically treated in specialized centers.

OBJECTIVE: There is no consensus on the best option for the management of Bartholin's gland abscesses. This systematic review and meta-analysis aimed to compare the Word catheter placement and marsupialization methods in the management of women with a cyst or abscess of the Bartholin's glands. DATA SOURCES: The PubMed, Scopus, Embase, Web of Science, and Cochrane Library databases, as well as Google Scholar, were searched to retrieve articles published between January 1990 and July 2023, comparing the Word catheter treatment with marsupialization for women with a cyst or abscess of the Bartholin's glands. STUDY SELECTION: Both observational studies and randomized controlled trials (RCTs) were included in this meta-analysis. DATA EXTRACTION AND SYNTHESIS: After the review, out of 9 relevant articles, only 4 (2 observational studies and 2 RCTs) were included in this meta-analysis, providing the data of 735 patients (396 in the Word catheter group vs. 339 in the marsupialization group). The data was extracted from the selected articles, using a data extraction form. Comparison of the Word catheter and marsupialization methods suggested that the risk of recurrence was approximately 7.6% in the Word catheter group and 9.4% in the marsupialization group. The findings indicated no significant difference in the recurrence of cysts or abscesses when comparing the Word catheter treatment with marsupialization (odds ratio = 0.99, 95% confidence interval: 0.29-3.43, P = 0.990, I2 = 77%). CONCLUSION: This meta-analysis found no significant difference in the rate of recurrence between the Word catheter and marsupialization methods. In general, marsupialization and Word catheter placement in the treatment of Bartholinitis seem to be equally effective.

BACKGROUND: The Internal Fixator (INFIX) is a popular method, known for its minimal invasiveness and short operation time, for treating anterior pelvic ring fractures. Studies have shown that postoperative complications may occur, including anterolateral femoral cutaneous nerve injury, the femoral nerve paralysis, and delayed fracture healing. These complications are believed to be related to surgical stimulation, an excessively long lateral end of the connecting rod, a small distance between the screw and bone surface, insufficient pre-bending of the connecting rod, and difficulties in fracture reduction. CASE PRESENTATION: We report two unique cases of lower abdominal pseudocyst complicated with suspected infection after INFIX treatment of pelvic fractures at our trauma center. Following surgical removal of the internal fixation, resolution of the cysts was observed in both patients, and subsequent postoperative follow-up revealed the absence of any residual sequelae. These cases have not been reported in previous literature reviews. DISCUSSION: The lower abdominal cysts, potentially arising from the dead space created during intraoperative placement of the INFIX rod, may increase infection risk. The etiology remains uncertain, despite the presence of abnormal inflammation markers in both cases, and staphylococcus aureus found in one. These cysts were confined to the lower abdomen, not involving the internal fixation, and hence, only the INFIX was removed. Postoperative oral cefazolin treatment was successful, with resolved pseudocysts and no subsequent discomfort. CONCLUSION: We report two unprecedented cases of post-INFIX abdominal cysts, with a suspected link to intraoperative dead space. Despite uncertain etiology, successful management involved INFIX removal and oral cefixime therapy. These findings necessitate further exploration into the causes and management of such complications.

PURPOSE: The aim of this study was to evaluate the treatment outcomes of neuroendoscopic cyst partial resection (ECPR) combined with stereotactic radiotherapy (SRT) for cystic craniopharyngiomas. METHODS: In this retrospective study, 22 craniopharyngioma patients undergoing ECPR combined with SRT were included. This combination therapy was indicated for suprasellar cystic craniopharyngiomas in patients whose pituitary function was preserved but would be difficult to preserve in direct surgery. The outcomes of combination therapy, including tumor control and postoperative visual and pituitary functions, were investigated. RESULTS: ECPR was safely performed, and cyst shrinkage was accomplished in all cases. After ECPR, visual function improved in 12 of 13 patients (92%) with visual field disturbance and did not deteriorate in any patients. Pituitary function was preserved in 14 patients (64%) and deteriorated in eight patients (36%) after ECPR. As a complication of ECPR, meningitis occurred because of a wound infection in one patient. In 18 of 22 patients (82%), the tumor was controlled without further treatment 19 - 87 months (median, 33 months) after SRT. Hypopituitarism was an adverse event after SRT in two of the 18 patients who achieved tumor control. Four patients (18%) had enlarged cysts after SRT. Postoperative pituitary function was significantly more likely to deteriorate in cases of extensive detachment from the ventricular wall, and retreatment was significantly more common in cases with hypothalamic extension. CONCLUSION: Although limited to some cases, ECPR combined with SRT is a less invasive and useful therapeutic option for suprasellar cystic craniopharyngiomas. However, its long-term prognosis requires further evaluation.

BACKGROUND: Our aim was to determine whether the Apparent Diffusion Coefficient is able to predict the presence of a symptomatic pineal cyst by detecting cerebral edema. METHODS: We retrospectively analyzed MRIs of 45 patients with pineal cysts before and after resection and 51 patients without pineal cysts, comparing ADC values of thalamus, central, periventricular and subcortical white matter. Furthermore we evaluated cyst size and morphology and analyzed its correlation to ADC values in corresponding patients. RESULTS: Differences between patients with symptomatic pineal cyst and control group were not significant (p = 0.200 - 0.968). ADC ratios did not change significantly after resection of the cyst (p = 0.575 - 0.862). Cyst size showed no significant correlation to ADC ratios (p = 0.071 - 0.918). Raw data analyses revealed more significance, especially periventricularly and in central white matter, which resulted in significant interhemispheric differences in ADC ratios in both subgroups (p < 0.001 and p = 0.031). MRI of 1.5T showed consistently higher values than 3T but mostly insignificant. CONCLUSION: Our analysis revealed no evidence that pineal cysts lead to intracerebral edema caused by venous compression. Since variability was higher than the differences seen, ADC sequences do not appear to be an appropriate diagnostic tool for symptomatic pineal cysts.

The presence of hip paralabral cysts on magnetic resonance imaging is associated with labral tears and more extensive chondral damage. The 2-year follow-up results of patients with paralabral cysts are equivalent to patients who do not have paralabral cysts. However, since paralabral cysts are associated with more prearthritic hip cartilage damage, surgically addressing these hips sooner could yield better outcomes. Further research is needed to see if performing hip arthroscopy on patients with paralabral cysts more urgently yields better long-term outcomes than delaying surgery.

Tailgut cyst is a rare cystic disease of the anterior sacral surface and the remains of an embryonic tail gut. Tailgut cysts have a potential for malignancy, and complete resection with an adequate surgical margin is necessary. Even if incomplete resection does not result in recurrence of malignant disease, there is a risk of local infection leading to refractory fistulas. The optimal treatment for such refractory recurrent lesions has not been reported. We describe a case in which the combination of laparoscopic and transsacral approaches was effective for resecting a recurrent refractory fistula after incomplete resection of a tail gut cyst.

A primary orbital respiratory cyst is a congenital choristoma that presents in the orbit and with different signs and symptoms depending on the location, which might also change the surgical approach. The aim of this report is to describe 2 new cases of primary respiratory epithelial cysts and to review the literature on presentation, management, and risk factors with different surgical approaches and complications. Two cases presenting with gradually increased proptosis had a confirmed diagnosis of a respiratory epithelial cyst. CT and MRI imaging revealed a thin-walled intraconal cystic lesion. Complete surgical removal was not possible and an incisional biopsy of the wall was performed. Rarely, orbital respiratory epithelium cysts are primary lesions. The high risk of breaking the capsule during surgery and the presence of residual epithelial cells within the orbit may cause cyst's recurrence. Indeed, we recommend careful attention during dissection maneuvers and a long-term follow-up.

BACKGROUND: Mesenteric cysts have been typically described as cystic lesions of mesentery or omentum occurring either intra-abdominally or in the retroperitoneum. With no typical symptoms, the preoperative diagnosis of mesenteric cyst becomes challenging to establish. PATIENT AND METHODS: In this case report, we describe the case of a 29-year-old female who presented with abdominal distension for seven years associated with intermittent constipation. Following complete history, a meticulous physical examination was performed. Laboratory investigations and radiological imaging techniques were used to facilitate the diagnosis which was confirmed on laparotomy. RESULTS: Physical examination revealed abdominal ascites. Laboratory investigations were unremarkable. Abdominal ultrasound revealed multiloculated massive ascites. A well-defined cystic area 27 × 18cm displacing abdominal viscera was observed on computed tomography (abdomen and pelvis) with contrast medium. Exploratory laparotomy revealed a massive cyst involving almost the entire peritoneal cavity. On histopathology, no signs of malignancy were reported. The post-operative course was excellent, and the patient was discharged following surgery. CONCLUSION: As this lesion is rarely considered preoperatively, and the clinical manifestations can be non-specific, we report this case of mesenteric cyst mimicking ascites in order to inform improved decision making among healthcare professionals regarding the timely diagnosis and appropriate management.

PURPOSE: Paraovarian cysts in children and adolescents can be challenging to accurately diagnose prior to surgery. Our objective is to outline the clinical characteristics of paraovarian cysts and enhance the precision of diagnosing paraovarian cysts in this age group. METHODS: We retrospectively analyzed all patients with paraovarian cysts who underwent surgery in our department from 2013 to 2021. The review focused on demographic characteristics, clinical manifestations, intraoperative findings, and postoperative pathology of these patients. RESULTS: This cohort was composed of 38 children with paraovarian cysts. The average diameter of the cysts was 4.8 cm (range 0.5-10 cm). Among the cases, 25 (65.8%) had adnexal torsion. Postoperative pathology showed that all cases were simple cysts with serous fluid. After the procedure, the patients were monitored for a period ranging from 12 to 108 months. B-ultrasound and physical examination did not reveal any significant abnormalities. CONCLUSIONS: B-ultrasound can help diagnose paraovarian cysts by detecting slight deviation movement between the cyst and the uterus. The presence of adnexa torsion in children and adolescents with paraovarian cysts does not depend on BMI, but rather on the size of cysts. Laparoscopic cyst removal has proven to be an effective surgical approach with favorable outcomes.

This case study systematically assessed diverse approaches to sinus augmentation in the presence of sinus pathology. Three patients were carefully selected and categorized as pseudocyst (PsC) (type 1), mucous retention cyst (MRC) smaller than 20 mm (type 2), and MRC larger than 20 mm in size (type 3). All patients underwent sinus augmentation procedures, with each case utilizing a unique surgical approach. Spontaneous drainage was performed for the patient with PsC (type 1), followed by uncomplicated sinus augmentation. For the patient with an MRC smaller than 20 mm (type 2), aspiration of the cyst contents preceded sinus augmentation. Conversely, the patient with a larger MRC (type 3) underwent cyst enucleation followed by sinus augmentation after complete recovery of the sinus membrane. No complications were noted in any of the cases, and follow-up revealed stable implant installation at the site of sinus augmentation. Within the constraints of this study, the choice of surgical procedure, whether involving spontaneous drainage, aspiration, or enucleation, should be guided by an anticipated pathologic diagnosis and the size of the sinus cyst. This informed approach empowers clinicians to make well-informed decisions for the best possible outcomes and sustained results. Overall, this study offers valuable insights for clinicians seeking to optimize sinus augmentation procedures in the presence of sinus pathology.

Ependymal cysts represent congenital brain malformations rarely described in human medicine, where surgical resection is the treatment of choice. In veterinary medicine, only three cases have been previously reported, with one partially resected with surgery. A 6 yr old entire male American Staffordshire terrier was referred with a 4 mo history of incoordination and collapsing episodes with extensor rigidity. Neurological examination localized the lesion to the left central vestibular system and cerebellum. A brain computed tomography scan showed a hypoattenuating lesion with peripheral contrast enhancement in the fourth ventricle consistent with a cyst and secondary hydrocephalus. Treatment with prednisone was initiated, but despite an initial improvement, neurologic signs recurred and a suboccipital craniectomy to remove the cyst was performed. The cyst was first drained, and the capsule was carefully resected. The histopathological evaluation revealed a simple cubic to cylindrical epithelium with apical cilia and loose surrounding fibrillar tissue consistent with an intraventricular ependymal cyst. Four and a half years after surgery, the dog only shows short episodes of balance loss when turning abruptly but is otherwise neurologically normal. To the authors' knowledge, this is the first reported ependymal cyst in the fourth ventricle of a dog with successful surgical resection.

OBJECTIVES: To compare the intraoperative and postoperative outcomes of sublabial excision and transnasal endoscopic marsupialization, the two primary surgical approaches for nasolabial cysts. DESIGN AND SETTING: A comprehensive meta-analysis of studies identified from PubMed, Embase, and the Cochrane Library. PARTICIPANTS: Patients diagnosed with nasolabial cysts who underwent surgical treatment. MAIN OUTCOME MEASURES: Operative time, postoperative pain, overall postoperative complications, admission rate, length of hospital stay, use of general anaesthesia, medical costs, and recurrence rate. RESULTS: The pooled analysis revealed that the transnasal endoscopic marsupialization group had shorter operative time (mean differences [MD], -32.51; 95% confidence interval [CI], -38.52 to -26.51), reduced postoperative pain (MD, -4.25; 95% CI, -7.62 to -0.89), fewer overall postoperative complications (risk difference [RD], -0.68; 95% CI, -0.90 to -0.46), lower admission rates (RD, -0.86; 95% CI, -1.11 to -0.61), shorter hospital stays (MD, -1.74; 95% CI, -2.58 to -0.89), decreased use of general anaesthesia (RD, -0.40; 95% CI, -0.76 to -0.03), and reduced medical costs (MD, -229.69; 95% CI, -338.64 to -120.75). The recurrence rate between the two groups showed no significant difference (RD, -0.01; 95% CI, -0.05 to 0.04). CONCLUSION: Transnasal endoscopic marsupialization presents as a promising alternative to sublabial excision in the treatment of nasolabial cysts. It offers advantages like reduced operative time, decreased postoperative pain, fewer complications, lower admission rates, shorter hospital stays, diminished need for general anaesthesia, and cost savings. Clinicians can leverage these findings to select the most suitable surgical approach for their patients.

INTRODUCTION: Cystic adventitial disease (CAD) is an uncommon condition that affects arteries and veins. It can cause a rare type of non-atherosclerotic peripheral vessel disease. The most common vessel affected is the popliteal artery. The number of case reports on CAD of the femoral artery is growing. We present a case of a 62-year-old female presented with claudication of the left leg diagnosed with CAD of the left common femoral artery. The patient was treated surgically with cyst excision and vessel reconstruction with saphenous vein autograft patch plasty. After 8-months the cyste relapsed and she had new claudication complains. We decided to perform new surgery. Surgical treatment consisted of cyst resection by excision of the femoral bifurcation and saphenous vein autograft interposition reconstruction of the bifurcation. We also provide an update on the latest literature of surgical treatment of CAD of the ilio-femoral artery region. METHODS: Medline and EMBASE were used to collect articles on CAD of ilio-femoral artery. We included English written or translated case reports or series between 1987 and 2023. RESULTS: Twenty-nine patients out of 28 case reports were included. Most patients were male (59%). Claudication is the most common symptom (76%). Treatment consisted of cyst resection, cyst decompression, Endarterectomy, patch angioplasty and interposition graft using PTFE, Dacron, Great saphenous vein (GSV) or femoral vein autograft. Recurrence appeared in 4 cases (14%). CONCLUSION: In accordance to the literature and our experience we recommend complete vessel excision and saphenous vein (or PTFE) interposition bypass as treatment.

INTRODUCTION: The updated Bosniak classification in 2019 (v2019) addresses vague imaging terms and revises the criteria with the intent to categorise a higher proportion of cysts in lower-risk groups and reduce benign cyst resections. The aim of the present study was to compare the diagnostic accuracy and inter-observer agreement rate of the original (v2005) and updated classifications (v2019). METHOD: Resected/biopsied cysts were categorised according to Bosniak classifications (v2005 and v2019) and the diagnostic accuracy was assessed with reference to histopathological analysis. The inter-observer agreement of v2005 and v2019 was determined. RESULTS: The malignancy rate of the cohort was 83.6% (51/61). Using v2019, a higher proportion of malignant cysts were categorised as Bosniak ≥ III (88.2% vs 84.3%) and a significantly higher percentage were categorised as Bosniak IV (68.9% vs 47.1%; p = 0.049) in comparison to v2005. v2019 would have resulted in less benign cyst resections (13.5% vs 15.7%). Calcified versus non-calcified cysts had lower rates of malignancy (57.1% vs 91.5%; RR,0.62; p = 0.002). The inter-observer agreement of v2005 was higher than that of v2019 (kappa, 0.70 vs kappa, 0.43). DISCUSSION: The updated classification improves the categorisation of malignant cysts and reduces benign cyst resection. The low inter-observer agreement remains a challenge to the updated classification system.

For a large benign lesion within the maxillary sinus, such as an antral pseudocyst, maxillary sinus floor augmentation is more commonly performed using a two-stage approach. This involves first removing the lesion, and then, re-entry following several months of healing. In this case series, we described the "one-bony-window" approach, which is a technical surgical modification of the previous one-stage approach, for simultaneous cyst removal and maxillary sinus floor augmentation. Four patients with large maxillary antral pseudocysts were included. The "one-bony-window" approach involves the preparation of a large window opening of approximately 15 mm × 20 mm at the lateral wall. A mesiodistally extended intentional perforation was made in the upper part of the exposed membrane to enhance the access for instrumentation. The antral pseudocyst was removed in its entirety without being deformed to prevent rupture or leakage of the cystic contents. Subsequent detachment and elevation of the Schneiderian membrane at the sinus floor significantly reduced the perforation site, and bone grafting with implant placement was performed simultaneously. This alleviated the need to surgically repair the perforation. The lateral opening was either uncovered or repositioned using bony window lids. Healing abutments were connected after six months, and the final prosthesis was placed after two months. At the 1-year follow-up, the antral pseudocysts had resolved with no specific recurrence, and the stability of the augmented sinus was maintained with excellent implant survival. Within the limitations of our findings, the "one-bony-window" technique can be suggested for the simultaneous removal of large antral pseudocysts and maxillary sinus floor augmentation with favorable clinical outcomes.
