Curettage combined with decompression for the treatment of ameloblastoma in children: report of two cases.

BACKGROUND: Ameloblastoma (AM) is the most common benign odontogenic tumor, which is more often detected in the mandible than maxilla, especially the mandibular body and mandibular angle. Pediatric AM is a rare disease, especially in patients aged 10 and younger. Compared with the mainstream osteotomy and reconstructive surgery for adult ameloblastoma, there is more room for discussion in the treatment of pediatric ameloblastoma. The postoperative functional and psychological influence can not be ignored. Especially for children in the period of growth and development, an osteotomy is often challenging to be accepted by their parents. We report two patients with ameloblastoma under 10 years old who are treated with curettage and fenestration, which is a beneficial method for children with ameloblastoma. CASE PRESENTATION: We present two cases of classic ameloblastoma in children. We describe in detail the patients' characteristics, treatment processes, and follow-up result. The bone formation and reconstruction in the lesion area after fenestration decompression and curettage are recorded at every clinic review. The surgical details and principles of curettage and decompression are also described and discussed. The two patients have good bone shape recovery and no recurrence. CONCLUSIONS: Children are in the growth and development period and possess an extremely strong ability of bone formation and reconstruction. Based on the principles of minimally invasive and functional preservation, we believe that curettage combined with decompression can be the first choice for treating AM in children, especially for mandibular lesions.

Treatment of Unicameral Bone Cysts Utilizing the Sclerograft™ Technique.

PURPOSE: To evaluate the Sclerograft™ procedure, which is an image-guided, minimally invasive approach of chemical sclerotherapy followed by bone grafting of unicameral bone cysts (UBC). MATERIALS AND METHODS: A retrospective evaluation from August 2018 through August 2023 was performed at a single institution on patients that underwent the Sclerograft™ procedure for UBCs. Radiographic healing was evaluated utilizing the Modified Neer Classification. Two different regenerative grafts, CaSO4-CaPO4 and HA-CaSO4 were utilized. A total of 50 patients were evaluated with 41 patients grafted with CaSO4-CaPO4 and 9 patients grafted with HA-CaSO4. RESULTS: The average age of the patient was 12.1 years with an average radiographic follow-up of 14.5 months. Average cyst size was 5.5 cm in the largest dimension and average cyst volume was 20.2 cc. 42 out of 50 (84%) showed healed cysts (Modified Neer Class 1) on the most recent radiograph or MRI. Recurrences occurred on average at 7.2 months. Activity restrictions were lifted at 3-4.5 months post-procedure. Cyst stratification by size did not show a difference in recurrence rates (p = 0.707). There was no significant difference in recurrence rate between lesions abutting the physis compared to those that were not abutting the physis (p = 0.643). There were no major complications. CONCLUSIONS: The Sclerograft™ procedure is an image-guided approach to treating unicameral bone cysts, utilizing chemical sclerosis and regenerative bone grafting. The radiographic healing of cysts compares favorably to open curettage and grafting as determined utilizing previously published trials.

Extended curettage for tumour-induced osteomalacia in the bone.

BACKGROUND: extended curettage is generally used to treat infiltrative bone tumours. However, the extent of the curettage performed in previous studies remains unclear. This study aimed to investigate the efficacy of extended curettage for bone tumour-induced osteomalacia. METHODS: we included 12 patients with tumour-induced osteomalacia who underwent extended curettage at our hospital between 2000 and 2022. Extended curettage was applied in cases where tumour resection could cause functional impairment or necessitate complex reconstruction. We investigated patients' clinical and oncological outcomes. RESULTS: patients had a mean age of 55 (24-81) years, and the median follow-up duration after surgery was 3.9 (1.0-14.0) years. The causative tumours were located in the pelvis and lumbar spine. Imaging revealed the tumours to be of the sclerotic, intertrabecular, lytic and mixed types. Intraoperative 3D fluoroscopy was used in 10 patients. Extended curettage with high-speed burring and adjuvant therapy with cauterization using an electric scalpel and ethanol resulted in a remission rate of 83%; no recurrence or metastasis was observed in cases of early postoperative biochemical remission. In cases where the causative tumour was at the lumbar spine and ischium close to the acetabulum, no postoperative biochemical remission was observed, and conservative treatment was continued. Except for one patient with a tumour in the lumbar spine, all patients could walk without a cane. CONCLUSIONS: extended curettage for bone tumour-induced osteomalacia is oncologically and functionally favourable, especially in cases where resection of the causative tumour could cause functional impairment or necessitate complex reconstruction.

Use of Surgical Adjuvants Does Not Decrease Recurrence of Aneurysmal Bone Cysts in Surgical Intervention With Pediatric Patients.

BACKGROUND: Aneurysmal bone cysts (ABCs) are benign active tumors often requiring intralesional curettage with or without adjuvants. The primary aim of this study was to analyze whether recurrence is influenced by the use of surgical adjuvants in pediatric patients with ABCs. Secondary aims examined recurrence rates based on age, sex, and physeal contact. METHODS: A retrospective review was performed at a tertiary pediatric hospital from 2004 to 2020. Inclusion criteria consisted of patients treated surgically for histologically confirmed ABCs with a minimum of 6 months follow-up. Patients with treatment for a recurrent tumor or incomplete records were excluded. Patient demographics, location of the lesion, treatment technique, and incidence of recurrence were collected. Statistical analyses were performed using STATA. RESULTS: There were 129 patients (74 males and 55 females) with a mean age of 11.5 ± 4.1 years and an average follow-up of 29.0 ± 25.4 months. The most common locations for ABCs were the femur and tibia. Of the patients, 53.5% had tumors abutting the physis, 28.7% had no physeal contact, and 17.8% had insufficient imaging to evaluate physeal contact. Surgical adjuvants (high-speed burr, coagulation, liquid nitrogen, and/or hydrogen peroxide) were used in 91 of the 129 cases (70.5%). There was no significant difference in recurrence when comparing those who received an adjuvant and those who did not (25.3% vs 23.7%, P = 1.000). Physeal contact was also not significantly associated with recurrence ( P = 0.146). Finally, patients younger than 6 years old were significantly more likely to have recurrence compared with those 6 years old or older (66.7% vs 21.7%, P = 0.007). CONCLUSION: Our study found no association between the use of surgical adjuvants and the risk of recurrence after intralesional curettage for ABCs. Although our study did demonstrate that patients 6 years old or younger had an increased rate of recurrence, no significant association was found regarding physeal contact or sex. These data indicate that surgical adjuvant may not affect the recurrence rates of pediatric patients with ABCs. LEVEL OF EVIDENCE: Level III. This retrospective review compares rates of recurrence based on the choice of surgical adjuvant.

Fracture risk after intralesional curettage of atypical cartilaginous tumors.

INTRODUCTION: The need for curettage of atypical cartilaginous tumors (ACT) is under debate. Curretage results in defects that weaken the bone potentially leading to fractures. The purpose of this study was to retrospectively determine postoperative fracture risk after curettage of chondroid tumors, including patient-specific characteristics that could influence fracture risk. METHODS: A total of 297 adult patients who underwent curettage of an ACT followed by phenolisation and augmentation were retrospectively evaluated. Explanatory variables were, sex, age, tumor size, location, augmentation type, and plate fixation. The presence of a postoperative fracture was radiologically diagnosed. Included patients had at least 90 days of follow-up. RESULTS: A total of 183 females (62%) were included and 114 males (38%), with an overall median follow-up of 3.2 years (IQR 1.6-5.2). Mean diameter of the lesions was 4.5 (SD 2.8) cm. Patients received augmentation with allograft bone (n = 259, 87%), PMMA (n = 11, 3.7%), or did not receive augmentation (n = 27, 9.1%). Overall fracture risk was 6%. Male sex (p = 0.021) and lesion size larger than 3.8 cm (p < 0.010) were risk factors for postoperative fracture. INTERPRETATION: Curettage of ACT results in an overall fracture risk of 6%, which is increased for males with larger lesions.

Assessment of middle ear function after conventional or endoscopic microdebrider assisted adenoidectomy.

Objectives: To compare pre- and post-operative pure tone audiometric and impedance audiometric analysis following conventional and endoscopic microdebrider assisted adenoidectomy and compare the outcomes. Methods: Patients diagnosed with chronic adenoiditis were divided in groups of 25 each. Patients in the first group underwent conventional curettage adenoidectomy, while those in second group underwent endoscopic microdebrider assisted adenoidectomy. Pre- and post-operative pure tone and impedance audiometry were performed for all patients and outcomes were compared. Results: The endoscopic microdebrider assisted method resulted in significantly better outcomes compared to conventional curettage. Criteria such as hearing threshold (p value 0.004 at second follow-up), peak pressure (p value 0.045 at first follow-up) and tympanogram (p value 0.016) showed that the endoscopic method was better, while peak compliance (p value 0.340 at first follow-up) did not show any significant difference between groups. Conclusions: The endoscopic microdebrider assisted method for adenoidectomy has a definite advantage of better visualisation resulting in better clearance of tissue, leading to enhanced middle ear function compared to conventional curettage.

Curettage and colour-A technique for defining tumour depth on the ear in the Mohs and non-Mohs setting.

For tumours of the ear that are suspected to involve auricular cartilage, precise definition of the extent of involved deep margin can be difficult. As large resections of cartilage can be cosmetically disfiguring with limited repair options, we propose a simple and effective technique to facilitate a targeted deep margin resection using a curette and a surgical marking pen.

Aneurysmal bone cyst: Is selective arterial embolization effective as curettage and bone grafting?

INTRODUCTION: Aneurysmal bone cyst (ABC) is a lytic benign bone lesion representing about 1% of all primary bone tumors. Method to treat ABC's have developed over time. The standard of care cure for ABC has been curettage with or without bone grafting of the defect but is burdened by recurrence rates of approximately 25%-31%. Based on the assumption that ABCs usually supplied by one or more pathological feeding arteries, selective arterial embolization has been described as an adjuvant preoperative procedure to reduce intra-operative hemorrhage, and as primary treatment for lesions in difficult surgical access. In the current study, we therefore asked whether (1) a single or a repeat selective arterial embolization (SAE) for treating ABCs would produce comparable healing rates compared with curettage and bone grafting; (2) evaluated the relationship of recurrence in relation to the site of the cyst, the age, and gender of the patients; and (3) the two techniques differ in term of long-term complication. MATERIAL AND METHODS: We retrospectively reviewed 265 patients who underwent curettage and bone grafting or SAE performed at our institute from 1994 to 2018. The diagnosis of ABC was always established with percutaneous CT-guided biopsy or open biopsy. Patients were followed clinically with plain radiographs or CT scan at 3, 6, 9, and 12 months then annually in the absence of symptoms. Treatment success was determined evaluating pre- and postprocedural imaging according to Chang classification. RESULTS: Two hundred and nineteen were treated with curettage and bone grafting (curettage group), and 46 with SAE Group. Of the 219 patients treated with Curettage and bone grafting (curettage group), 165 out of 219 (75.3%) experienced bone healing, while local recurrence was observed in 54 cases (24.7%) after 12 months on average (range: 3-120 months) from surgery. After the first SAE, bone ossification was seen in 27 (58.7%), without needing any further treatment. Eleven recurred patients were treated with SAE (four patients need two while seven need three SAE to heal), and eight patients with curettage and bone grafting. Thirty-eight out of 46 (82%) patients experienced bone ossification regardless the number of SAE. The overall rate of local recurrence for all patients was 26.7%. SAE group presented a lower complication rate (6%) where two patients experienced skin necrosis, and one limb-length discrepancies (2% of all cohort). DISCUSSION: The use of SAE is an attractive option to treat ABC as it combines on one hand a lower complication rate than curettage and bone grafting, on the other it can be carried out in case of nonresectable ABCs, significantly reducing the size of viable ABC lesions, fostering bone remodeling and mineralization, and most importantly, significantly improving the patient's quality of life.

The effect of adjuvant cryotherapy added to well-performed high-speed burr curettage on the long-term surgical outcomes of chondroblastoma cases.

OBJECTIVES: This study aims to investigate the effect of adjuvant cryotherapy added to well-performed high-speed burr curettage on the long-term surgical outcomes of chondroblastoma cases. PATIENTS AND METHODS: Between January 2004 and December 2020, a total of 30 chondroblastoma cases (19 males, 11 females; median age: 18.6 years; range, 9 to 53 years) who were surgically treated were retrospectively analyzed. The pressurized-spray technique was performed using liquid nitrogen. Data including age, sex, radiological appearance, treatment modality, duration of follow-up, skin problems, and recurrence were recorded. All patients received adjuvant liquid nitrogen cryotherapy after extended intralesional curettage with high-speed burr. The bone cavity was filled with an autologous iliac crest bone graft, allograft, or polymethylmethacrylate (PMMA). RESULTS: The median follow-up was 54 (range, 19 to 120) months. The lesion was located around the knee in 16 (53.3%), in the shoulder in seven (23.3%), around the hip in five (16.6%), and in the ankle in two (6.6%) cases. The defect was filled with an autologous iliac crest bone graft in 28 (93.3%), an additional allograft in eight (26.7%), and PMMA in two (6.7%) cases. Local recurrence was observed in only two (6.7%) patients during follow-up. Two (6.7%) patients developed physeal growth arrest. Osteoarthritic changes were observed in two (6.7%) patients (one knee and one hip) due to the periarticular location of the tumor. Three (10%) patients had skin complications. None of the cases had a pathological fracture. CONCLUSION: A well-performed extended intralesional curettage with high-speed burr is the first and essential step in treating chondroblastoma. Adding adjuvant liquid nitrogen cryotherapy with high-speed burr can improve treatment outcomes and significantly reduce the recurrence rate of this disease.

Cryosurgery versus curettage for intraepidermal carcinoma: A randomized controlled trial.

BACKGROUND: Cryosurgery is a common destructive treatment method for intraepidermal carcinoma (IEC) above the knee. Curettage alone is a simple, non-aggressive and inexpensive treatment method commonly used on benign skin lesions. However, only one study has assessed curettage for treatment of IEC. OBJECTIVE: We aimed to (1) compare the effectiveness of cryosurgery (standard method) to curettage (experimental method) for treatment of IEC in regard to overall clearance rates at 1-year follow-up, and (2) investigate whether wound healing times differed between the treatment groups. METHODS: In this randomized and controlled, non-inferiority trial, adult patients with one or more IEC with a diameter of 5-20 mm, located above the knee and suitable for destructive treatment were recruited from Sahlgrenska University Hospital (Gothenburg, Sweden). Lesions were randomized to treatment with either cryosurgery or curettage. Wound healing was assessed by a nurse after 4-6 weeks and through self-report forms. Overall clearance was assessed by a dermatologist after 1 year. RESULTS: In total, 183 lesions in 147 patients were included, with 93 lesions randomized to cryosurgery and 90 to curettage. Eighty-eight (94.6%) of the lesions in the cryosurgery group and 71 (78.9%) in the curettage group showed an overall clearance at the 1-year follow-up visit (p = 0.002). The non-inferiority analysis was inconclusive. Curettage resulted in both shorter self-reported wound healing times (mean time 3.1 vs. 4.8 weeks, p < 0.001) and a larger proportion of healed wounds after 4-6 weeks (p < 0.001). CONCLUSIONS: Cryosurgery and curettage both result in high clearance rates for treatment of IEC, but cryosurgery is significantly more effective. On the other hand, curettage may result in shorter wound healing times.

Functional and oncological outcome of patients with benign hindfoot tumors treated by curettage.

BACKGROUND: Only 3 % of osseous tumors occur in the foot. The metatarsals are the -most common site whereas the calcaneus and talus are less common sites. Because these tumors are rare, the aim of our study is to assess the functional and the oncological outcome of patients with benign hindfoot tumors managed by curettage. METHODS: The clinical and radiological data of 41 patients diagnosed with benign hindfoot tumors were retrospectively reviewed. The study included 31 males and 10 females. The average age was 23.68 (range, 5-49) years. The average follow-up period was 92.7 (range, 12-244) months. RESULTS: At the last follow-up visit, the average Musculoskeletal Tumor Society scoring system (MSTS) score was 28.12 (range, 21-30). MSTS scores were higher in patients with latent tumors (P = .028) and patients managed by simple curettage (P = .018). The recurrence rate in calcaneal tumors was higher than those in the talus. The overall complication rate was 12.2 % (5 of 41 patients). Infection and subtalar arthritis were the most common complications. CONCLUSION: Curettage of benign bone tumors of talus or calcaneus proved to be an effective method in the management of these patients. Their functional outcome is also excellent. All the complications are manageable without long term morbidity. LEVEL OF EVIDENCE: Level IV Therapeutic study.

Factors Affecting Postoperative Complications of Suction-Curettage by Arthroscopic Shaver for Bromhidrosis.

BACKGROUND: Suction-curettage by arthroscopic shaver is the most effective treatment for bromhidrosis; however, postoperative complications require wound management and exhibit a high risk of hypertrophic scarring. We investigated factors affecting postoperative complications. METHODS: We retrospectively evaluated data for 215 patients (430 axillae) with bromhidrosis treated with suction-curettage by arthroscopic shaver between 2011 and 2019. Cases followed for less than 1 year were excluded. Complications of hematoma or seroma, epidermis decortication, skin necrosis, and infection were recorded. Multinomial logistic analysis was used to calculate odds ratios and corresponding 95% confidence intervals for the complication of the surgery, adjusting for relevant statistically significant variables. RESULTS: Complications occurred in 52 axillae (12.1%). Epidermis decortication occurred in 24 axillae (5.6%), with a significant difference for age (P < 0.001). Hematoma occurred in 10 axillae (2.3%) with a significant difference in tumescent infiltration use (P = 0.039). Skin necrosis occurred in 16 axillae (3.7%) with a significant difference for age (P = 0.001). Infection occurred in 2 axillae (0.5%). Severe scarring occurred in 15 axillae (3.5%), with complications related to more severe skin scarring (P < 0.05). CONCLUSION: Older age was a risk factor for complications. Use of tumescent infiltration resulted in good postoperative pain control and less hematoma. Patients with complications presented with more severe skin scarring, but none experienced limited range of motion after massage.

Incidence and progression of osteoarthritis following curettage and cementation of giant cell tumor of bone around the knee: long-term follow-up.

BACKGROUND: Giant cell tumor of bone (GCTB) is a benign locally aggressive tumor frequently treated with intralesional curettage and cementation. The aim of this study was to investigate the long-term incidence of arthritic changes following curettage and cementation of GCTB around the knee. MATERIALS AND METHODS: This study was a retrospective review of patients with GCTB around the knee treated with curettage and cementation with a minimum follow-up of 10 years. The functional results were assessed using the Musculoskeletal Tumor Society (MSTS) score. The arthritic changes were classified using the Kellgren-Lawrence (KL) classification system of osteoarthritis. RESULTS: This study included 119 patients, 54 males and 65 females, with a mean age of 29.4 ± 9.2 years. There were 35 (29.4%) patients with pathological fractures. There were 84 (70.6%) patients with de novo lesions and 35 (29.4%) with recurrent lesions. The mean follow-up period was 13.2 ± 3.16 years. The mean MSTS score was 28.5 ± 1.9. Overall, 25 (21%) patients developed variable degrees of arthritis of KL grade 1 (n = 7), KL grade 2 (n = 11), KL grade 3 (n = 4), and KL grade 4 (n = 3). Ten patients showed progression of arthritis during the follow-up period. Age at presentation, gender, presence of pathological fracture, whether the tumor was de novo or recurrent, and tumor location were not associated with arthritis incidence. CONCLUSIONS: Curettage and cementation can be used safely to treat GCTB around the knee. Arthritis of the knee is a possible complication, but mild grades are expected in most cases. There was no association between arthritis incidence and age, gender, pathological fractures, tumor location, or recurrent tumors. LEVEL OF EVIDENCE: Level IV.

Giant cell tumour of bone.

Giant cell tumour of bone (GCTB) is a locally aggressive lesion that is difficult to treat as salvaging the joint can be associated with a high rate of local recurrence (LR). We evaluated the risk factors for tumour relapse after treatment of a GCTB of the limbs. A total of 354 consecutive patients with a GCTB underwent joint salvage by curettage and reconstruction with bone graft and/or cement or en bloc resection. Patient, tumour, and treatment factors were analyzed for their impact on LR. Patients treated with denosumab were excluded. There were 53 LRs (15%) at a mean 30.5 months (5 to 116). LR was higher after curettage (18.4%) than after resection (4.6%; p = 0.008). Neither pathological fracture (p = 0.240), Campanacci grade (p = 0.734), soft-tissue extension (p = 0.297), or tumour size (p = 0.872) affected the risk of recurrence. Joint salvage was possible in 74% of patients overall (262/354), and 98% after curettage alone (262/267). Of 49 patients with LR after curettage, 44 (90%) underwent repeated curettage and joint salvage. For patients treated by curettage, only age less than 30 years (p = 0.042) and location in the distal radius (p = 0.043) predicted higher LR. The rate of LR did not differ whether cement or bone graft was used (p = 0.753), but may have been reduced by the use of hydrogen peroxide (p = 0.069). Complications occurred in 15.3% of cases (54/354) and did not differ by treatment. Most patients with a GCTB can undergo successful joint salvage by aggressive curettage, even in the presence of a soft-tissue mass, pathological fracture, or a large lesion, with an 18.4% risk of local recurrence. However, 90% of local relapses after curettage can be treated by repeat joint salvage. Maximizing joint salvage is important to optimize long-term function since most patients with a GCTB are young adults. Younger patients and those with distal radius tumours treated with joint-sparing procedures have a higher rate of local relapse and may require more aggressive treatment and closer follow-up.

Filling of the resultant cavity after curettage of benign bone tumours is still controversial.

INTRODUCTION: Benign bone tumours occur most commonly during the first through third decades of life and often weaken the bones, which may predispose them to pathological fractures. Great diversity and debate in the management of primary bone tumours are based on the tumour extent. There has been an increasing trend toward the intra-operative filling of these lesions. We hypothesised that in some benign bone tumours, filling the resulting cavity after curettage was unnecessary. This study was carried out to determine whether it is necessary to fill the resultant cavity after the curettage of benign bone tumours and to represent various fillers. MATERIALS AND METHODS: A retrospective study of patients diagnosed as benign bone tumours according to the Enneking classification who underwent simple or extended curettage at Menoufia university-Orthopedic Oncology Division (with or without grafting or filling) during the surgical treatment (Jan 2015 to Feb 2020). A review of the medical records was done. Lesions' size (length, width and depth) was measured on plain radiographs using the image j program. When applicable, degrees of filling of the resultant cavity were classified into four categories, according to Modified Neer's classification. Functional evaluation using the musculoskeletal tumour society (MSTS) score was reviewed. RESULTS: Overall, 88 patients diagnosed with a primary bone tumour and who received the surgical intervention were included in the study. The mean age of the patients was 22.61+13.497 (3-58) years. There were 48 males and 40 females (54 right and 34 left). The mean follow-up period was 28.09+16.13 months. The most common location was the distal femur in 15 patients, the proximal femur in 10 patients and the proximal tibia in 12 patients. The most common diagnosis was giant cell tumour in 20 patients, followed by UBC in 19 patients, ABC in 15 patients and enchondroma in 13 patients. Twenty-three patients had simple curettage, while 65 patients had extended curettage. Mean MSTS was 28.78±1.68. Fifty-five lesions were classified according to modified Neer's classification.Thirtty-two patients were classified as type 1 with complete healing,22 patient was classified as type 2 with partial healing, and only one was classified as a recurrent lesion. Seven patients (7.9%) developed local recurrences. CONCLUSION: Filling the resulting cavity after the removal of the pathological tissues is usually necessary but not always required. This is determined by the type of lesion and the size of the resulting cavity following curettage. Individualised surgery is required; additional fixation should be considered.

A comparative study of two adenoidectomy technics for efficacy and safety: Conventional curettage adenoidectomy versus endoscopic microdebrider adenoidectomy.

PURPOSE: Conventional cold curettage adenoidectomy (CCA) is the most used method for Adenoidectomy. With the advances in surgical instruments, endoscopy assisted less invasive techniques are coming into use. Herein we compared CCA with endoscopic microdebrider adenoidectomy (EMA) in terms of safety and recurrence. METHODS: Patients who underwent adenoidectomy in our clinic between 2016 and 2021 years were included into the study. Study performed retrospectively. Patients operated with CCA accepted as GroupA and EMA as GroupB. Two groups compared for the recurrence rate and post-operative complications. RESULTS: We studied 833 children aged between 3 and 12 years (mean 4,2 years old), had adenoidectomy, including 482 male(57.86 %) and 351 female (42.14 %). There were 473 patients in GroupA, and 360 patients in GroupB. Seventeen patients (%3.59) in GroupA had reoperation for the recurrence of adenoid tissue. There was no recurrence in GroupB. Residual tissue, recurrent hypertrophy, and postoperative otitis media rates were higher in GroupA, and this was statistically significant (p < 0.05). Whereas ventilation tube insertion rates didn't differ significantly (p > 0.05). Although hypernasality rate at second week was slightly higher in GroupB, this was not statistically significant (p > 0.05), and in further period it resolved in all patients. No major complications were reported. CONCLUSION: Our study indicates that EMA is a safer technique than CCA, and prominent postoperative complications like residual adenoid tissue, recurrent adenoid hypertrophy, and postoperative otitis media with effusion rates are lower.

Efficacy and safety of super pulse CO2 laser-assisted punctoplasty with canalicular curettage in primary canaliculitis.

The objective of this study was to evaluate the efficacy and safety of super pulse CO2 laser-assisted punctoplasty with canalicular curettage in primary canaliculitis. In this retrospective serial case study, the clinical data of 26 patients who underwent super pulse CO2 laser-assisted punctoplasty for the treatment of canaliculitis were collected from January 2020 to May 2022. The clinical presentation, intraoperative and microbiologic findings, surgical pain severity, postoperative outcome, and complications were studied. Of the 26 patients, most were females (female:male 20:6), with a mean age of 60.1 ± 16.1 years (range, 19-93). Mucopurulent discharge (96.2%), eyelid redness and swelling (53.8%), and epiphora (38.5%) were the most common presentations. During the surgery, concretions were present in 73.1% (19/26) of the patients. The surgical pain severity scores ranged from 1 to 5, according to the visual analog scale, with a mean score of 3.2 ± 0.8. This procedure resulted in complete resolution in 22 (84.6%) patients and significant improvement in 2 (7.7%) patients, and 2 (7.7%) patients required additional lacrimal surgery with a mean follow-up time of 10.9 ± 3.7 months. The surgical procedure of super pulse CO2 laser-assisted punctoplasty followed by curettage appears to be a safe, effective, minimally invasive, and well-tolerated treatment for primary canaliculitis.

Long term outcome of surgical treatment of chondroblastoma: analysis of local control and growth plate/articular cartilage related complications.

BACKGROUND: Chondroblastoma (CBL) is a rare benign chondroid producing bone tumor that typically occurs in epiphysis or apophysis of growing children and young adults. Intralesional curettage is the treatment of choice, while resection is required in selected cases, even though the use of minimally invasive ablation techniques has been advocated. Authors reviewed a series of 75 CBLs with the aim of assess risk factors for local recurrence, the growth plate related complications after epiphyseal curettage and the risk of arthritis of the adjacent joint after epiphyseal curettage. METHODS: We retrospectively review 69 CBLs treated with intralesional curettage and 6 treated with resection from March 1995 to February 2020. The median age was 18.8 years (7 to 42, median 16). The site was proximal humerus in 18 cases, proximal tibia in 17, distal femur in 16, talus in 6, femur's head in 4, calcaneus in 3, acromion in 3, trochanteric region in 2, distal tibia in 2, patella in 2, supracetabular region in 1 and distal humerus in 1 patient. RESULTS: Mean follow-up was 124.2 months (24 to 322, median 116). Among patients treated with curettage, 7.3% of local recurrence was observed and 12 (17.4%) patients developed osteoarthritis of the adjacent joint. Five patients (7.3%) presented limb length discrepancy of the operated limb ranging from 0.5 to 2 cm. Recurrence free survival rate was 94.2% at 5 and 91.6% at 10 years. A mean Musculoskeletal Tumor Society (MSTS) of 29.3 points (20 to 30, median 30) was observed. CONCLUSION: More than 90% of CBLs were successfully treated with aggressive curettage but segmental resection is required in selected cases. In a relatively small proportion of cases long term complications can occur due to growth plate damage or osteoarthritis. TRIAL REGISTRATION: Retrospectively registered.

Management of giant cell tumors of the distal radius: a systematic review and meta-analysis.

PURPOSE: The treatment of giant cell tumors (GCT) of the distal radius remains challenging, with no consensus on the optimal surgical management. Surgical management remains the mainstay of treatment with options including intralesional curettage and en-bloc resection with reconstruction. The objective of this systematic review and meta-analysis was to evaluate and compare the outcomes of these two procedures. METHODS: Using OVID-Medline and Embase databases, a systematic literature search was performed. Comparative studies, assessing intralesional curettage and en-bloc resection in patients with GCTs of the distal radius, were included. Data regarding rates of local recurrence, metastasis, overall complications, and functional outcomes, were collected and analyzed. The ROBINS-I tool was utilized for risk of bias appraisal within each study outcome. RESULTS: Thirteen studies (n = 373 patients) reporting on 191 intralesional curettage procedures and 182 en-bloc resections were included in the analysis. The average age of participants was 31.9 (SD ± 2.4) years and average follow-up was 7.1 (SD ± 3.6) years. Patients that underwent intralesional curettage were more likely to develop local recurrence (Risk Ratio (RR) 3.3, 95% CI, [2.1, 5.4], p < 0.00001) when compared to patients that underwent en-bloc resection. In Campanacci grade 3 lesions, the risk for local recurrence was 5.9 (95% CI, [2.2, 16.3], p = 0.0006) times higher in patients that received intralesional curettage. Patients that underwent intralesional curettage showed an 84% reduction in the relative risk of developing overall complications compared to en-bloc resection (95% CI, [0.1, 0.4], p < 0.00001), and a larger decrease in Visual Analog Scale and lower Disabilities of the Arm, Shoulder, and Hand (DASH) scores (p < 0.00001). Risk ratio for developing a local recurrence, with PMMA versus bone graft following an intralesional procedure was not significant (RR 1.2, 95% CI, [0.6, 2.6], p = 0.62). CONCLUSIONS: In the surgical management of GCT of the distal radius, intralesional curettage increased local recurrence compared to en-bloc resection with reconstruction, particularly in grade 3 tumors. However, it led to significantly fewer operative complications, lower pain scores, and improved functional outcomes compared to en-bloc resection. Both treatment options remain relevant in the contemporary management of GCTs of the distal radius. Surgical decision making should include both patient and tumor factors when determining the optimal treatment strategy for these patients. LEVEL 3 EVIDENCE: Meta-analysis of Level 3 studies.

Comparing clinical outcomes between extended curettage and wide resection in Enneking stage 3 giant cell tumor of bone.

PURPOSE: Our objectives were (1) to compare the recurrence, metastases, and complication rates of patients with Enneking stage 3 GCTB who underwent extended curettage vs wide resection and (2) examine the factors which might influence surgical options for each patient. METHODS: We retrospectively reviewed the records of patients with Enneking stage 3 GCTB from January 2006-December 2015. Extended curettage was performed in patients in whom there was a moderate expansile lesion, minimal/no articular cartilage damage, and less than 50% of cortical deformation compared to its circumference from a CT scan/MRI. The percentages of cortical deformation were collected. Surgical complications, recurrence, and metastatic rates were analyzed. RESULTS: There were 28 extended curettage and 41 wide resections. The mean percentages of cortical deformation compared to circumference were 52.6% (range, 23.9-81.9%) and 91.6% (range, 52.1-100%)(P < 0.01) for the curettage and wide resection groups, respectively. There were three recurrences, 2/28 (7.1%) from the curettage group and 1/41 (2.4%) from the resection group (P = 0.56). There were no cases of pulmonary metastasis. There were two complications in the curettage group and five complications in the resection group. CONCLUSION: Both extended curettage and wide resection are useful methods to treat Enneking stage 3 GCTB. Extended curettage with proper technique is a viable option showing no difference in local recurrence rate and potentially fewer complications. Preference to do extended curettage in patients in whom when the articular cartilage has minimal or no destruction, a moderate expansile lesion and the cortical deformation is less than 50% of the circumference.
