Objectives: A mucous retention cyst is a common, asymptomatic lesion that may cause complications during or after the sinus lift procedure. The goal of this study is to assess the effectiveness of the Croco Eye Technique (CET), which allows simultaneous excision of the cyst and sinus floor elevation. Methods: The technique was thoroughly described in two versions, and the group of 33 patients was analyzed. Patients who qualified for this procedure had insufficient alveolar ridge height, and their CBCT showed radiological images typical for retention cysts. Analyzed parameters included the version of CET, demographic data, anatomical parameters, intraoperative complications, recurrence of the cyst, success rate of the sinus lift and implants, and the follow-up period. Results: Out of the 33 cases, 9 were of the primary version (27.27%) and 24 of the final version (72.73%). The average height of a retention cyst was 24.05 mm, with the average alveolar ridge height of 1.86 mm. In three cases (9.09%), implants were placed immediately. The prevalence of uncontrolled Schneiderian membrane perforation was reduced from 55.56% to 4.17% between the primary and final versions. The cyst\'s recurrence rate was 3.13%. The implant survival rate was 100%. The mean follow-up period was 48.625 months (max 110 months). Conclusions: The Croco Eye Technique, despite the perforation of the Schneiderian membrane, enables successful sinus lift and implantation with a success rate of 100%. Excision of the retention cyst, which is the cause of perforation, allows for limiting the risk of the cyst\'s recurrence.

Ranulas are cystic lesions located in the floor of the mouth. These are \"pseudocysts\" and are developed due to an obstruction in the sublingual gland. Congenital variants of plunging ranulas are very rare. Here, we report a case of an eight-year-old male child presenting with congenital swelling with an intraoral component as well as extension to the submandibular gland region. The swelling was painless and gradually growing in size.

UNASSIGNED: Mucous retention cysts and pseudoantral cysts are mainly located within the floor of the maxillary sinus. Most of these maxillary cysts are asymptomatic and often only require observation. However, the presence of these benign maxillary cysts may create problems when maxillary sinus all types of implants are needed. Various treatment methods have been introduced. The selected treatment option depends on the type, size, and location of the cyst and its symptoms. Patients and.
UNASSIGNED: The case reports of four patients with maxillary cysts were reviewed retrospectively. These patients received a sinus lift between January 2016 and October 2021 at the Wonkwang University Dental Hospital.
UNASSIGNED: To reduce unnecessary operations and the duration of treatment, a conservative treatment method is required. A sinus lift in the presence of maxillary cyst will not typically cause sinus problems if the lifted sinus membrane does not interfere with ventilation of the maxillary sinus.
UNASSIGNED: When proper treatment is provided, sinus perforation during a sinus lift performed in the presence of maxillary cyst and contamination of bone graft materials by cystic fluid does not necessarily result in adverse outcomes.

Mucocoeles can be defined as benign lesions that have resulted from extravasation or retention of saliva in the extraglandular spaces, and commonly affect the minor salivary glands. This case details a mucous retention cyst within the parotid gland of an infant, and its management.

Growth of any kind in the oropharynx poses a threat to the airway especially during anaesthesia. Being aware of the challenges and adequately equipped to handle the situation is the duty of the anesthesiologist.
UNASSIGNED: An eight year old girl diagnosed case of multiple mucous cysts presented to the outpatient department for excision of a lower lip mucous cyst. So an ultrasound was done which revealed a large intramural mucous cyst. After a preanaesthetic checkup she was posted for the excision of the cyst.
UNASSIGNED: The girl was posted for Elective surgery and was induced without prior premedication as she had revealed a history of snoring in supine position. After preoxygenating with 100% oxygen, she was induced with Injection Ketamine and Sevoflurane. She started desaturated abruptly so nasal airway and finally # 2.5 LMA was inserted but SpO2 didn\'t improve. With backup of Ent and paediatric surgeons direct larngoscopy was attempted and #5 ETT was inserted successfully. Following which the huge vallecular cyst was removed.

OBJECTIVE: Mucous retention cysts (MRCs) of the maxillary sinuses are incidental findings in radiographs of the oral and maxillofacial structures. These cysts usually appear as rounded, dome-shaped, and soft-tissue masses, most often on the floor of the maxillary sinus. The aim of this study was to determine the prevalence of maxillary antral MRC and the effect of seasonal variation, sex and age in cone beam computed tomography (CBCT) images.
METHODS: In this simple, nonrandomized, cross-sectional study, CBCT images of patients were reviewed to evaluate the prevalence of MRCs and its location in the antrum, uni or bilateral, size, and season in which MRC occurred. The findings were analyzed using Statistical software SPSS and t-tests (P > 0.05).
RESULTS: A total of 765 CBCT images were evaluated (380 males and 385 females); 180 were suggestive of MRCs, 110 occurred in males (28.9%) while 70 (18.2%) occurred in females, which resulted in a prevalence of 23.5%. The peak prevalence of MRC was found in spring (41.6% of all radiographs), but there was no significant statistical difference between the occurrence of MRCs in different seasons (P > 0.05).
CONCLUSIONS: This study showed no significant difference between the occurrences of MRCs in different seasons. There was no significant difference between male and female and different decades of life. Furthermore, there was no significant difference between the involvement of right and left maxillary sinuses and different walls of the antrum.

OBJECTIVE: The purpose of the present study was to evaluate the frequency, locations, and dimensions of mucous retention cysts of the maxillary sinus and analyze potential associated dental pathology.
METHODS: A total of 156 cone beam computed tomography (CBCT) scans were included in the analysis, resulting in an evaluation of 310 maxillary sinuses. The presence of mucous retention cysts (MRC) manifesting as dome-shaped radiopacities in the sinus was diagnosed. Their locations were recorded, and dimensions (mm) were measured in coronal and sagittal/axial slices. The patients were grouped into (a) patients/sinuses with MRCs (test), and (b) patients/sinuses with healthy or any other changes (control) for further comparison and evaluation.
RESULTS: There were 40 sinuses (12.9%) with a presence of a total of 56 MRCs. The mean age of involved patients was 29.0 years. The analysis showed that gender, age, sinus side, status of dentition, endodontic status, and periodontal status did not have a significant influence on the presence of MRCs when compared between test and control groups. Age and endodontic status exhibited a significant association with cyst location.
CONCLUSIONS: Most of the sinuses analyzed (79.5%) did not present any MRC, and only 28.6% of the cysts diagnosed were found on the floor of the maxillary sinus. The mean dimension of the MRCs measured 6.28 ± 2.93 mm. No influencing factors on the presence or absence of MRCs were found in the present study.
CONCLUSIONS: Most MRCs were not located on the floor of maxillary sinus. Future studies should assess their impact on surgical interventions in the sinus.

The salivary duct cyst (SDC) is a reactive ductal ectasia most frequently seen in major salivary glands, and likely caused by obstruction. The aim of this study is to define the clinical and histopathologic spectrum of intraoral SDCs. Cases were retrieved from the archives of Harvard School of Dental Medicine/StrataDx, Inc. from January 2012 to August 2014. There were 177 cases of which 103 (58.2%) occurred in females, with a median age of 56 (range 2-95). Approximately half of cases (45.8%) presented in the area of the buccal mucosa, lower lip mucosa, or mandibular vestibule, and 23.2% presented in the floor of mouth. SDCs were lined at least focally by 1-2 layers of cuboidal/columnar epithelium in 85.3% of cases and showed varying degrees of metaplasia (oncocytic, mucous cell, squamous, ciliated, apocrine-like) in 68.4% of cases. Intraluminal mucous stasis was present in 41.8% of SDCs, incipient calcification was present within 4.5% of SDCs, and chronic obstructive sialadenitis was seen in 90.2% of cases. No cysts showed adenomatous ductal proliferations or true papillary structures with fibrovascular cores, although 41.2% exhibited reactive undulation of cyst lining. Thirty-nine \'papillary oncocytic cystadenoma-like\' SDCs (22.0%) demonstrated complete oncocytic metaplasia and marked undulation. An additional seven such cysts (4.0%) had a \'Warthin tumor-like\' lymphoplasmacytic infiltrate. Intraoral SDCs occur most commonly in the sixth decade of life in locations distinct from extravasation mucoceles, likely secondary to intraluminal obstruction. SDCs show diverse histopathology and certain phenotypic variants may be mistaken for papillary oncocytic cystadenoma or Warthin tumor.

BACKGROUND: Mucous retention cyst refers to a cyst made by expansion due to the blockage of the salivary gland near the maxillary sinus, and it is surrounded by epithelial cells. Most of them are small; therefore, they cannot be found well and are frequently with antral polyp. The aim of this study was to evaluate the clinical prognosis of sinus bone graft in patients with mucous retention cyst.
METHODS: This study was performed retrospectively on 23 patients who had sinus bone graft. Group 1 was 8 patients (10 sinuses) who had a mucous retention cyst, and group 2 was 15 patients (17 sinuses) who had no pathologic history about the maxillary sinus. For these patients, sinus bone graft was performed using the lateral approach technique. The total 51 implants were placed 6.22 weeks on the average after sinus bone graft. Sinus membrane perforation during operation, postoperative complications, marginal bone loss after restorative function, implant success rate, and survival rate were analyzed.
RESULTS: There was no complication in group 1, and there were three complications in group 2. In group 2, two cases of implants failed. The types of postoperative complications consisted of two minor infections and one wound dehiscence. Two implants of total 51 implants were removed, and the survival rate of implants was 96.08 % (group 1 100 %, group 2 93.5 %). The total success rate of implants was 92.2 % (group 1 95 %, group 2 90.3 %).
CONCLUSIONS: The clinical prognosis was not affected by the presence of mucous retention cyst.

BACKGROUND: Mucous retention cysts are a subtype of intracordal vocal cysts that may occur spontaneously or may be associated with poor vocal hygiene, and which require optimal treatment. The objective of this study was to present a new laser-assisted microsurgery technique for treating intracordal mucous retention cysts and to describe the final outcomes.
METHODS: In this prospective study, we assessed the pre-operative and post-operative acoustic analysis, maximum phonation time (MPT), and voice handicap index (VHI) of four patients with a diagnosis of mucous retention cyst. The island flap technique was applied to all patients without any complications. In this procedure, we favored the super-pulse mode using a 2-W power CO2 laser to remove the medial wall of the cyst, before clearing away the lateral wall margins of the cyst using repeat-pulse mode and a 2-W power CO2 laser. Indeed, we maintained the underlying epithelium and lamina propria, including the island flap attached to the vocal ligament.
RESULTS: There was a statistically significant improvement in the MPT (pre-op,11.05 s; post-op,15.85 s; P=0.002) and the VHI (pre-operative, 72/120; post-operative,27/120; P=0.001) in all patients. Moreover, jitter and shimmer were refined after surgery, but there was no statistically significant relationship between pre-operative and post-operative data (P=0.071) (P=0.622). In the follow-up period (median, 150 days), there was no report of recurrence or mucosal stiffness.
CONCLUSIONS: The island flap procedure in association with CO2 laser microsurgery appears to be a safe and effective treatment option for intracordal mucous retention cysts, but needs further investigation to allow comparison with other methods.
