Orbital Reconstruction Using a Polyetheretherketone Patient-Specific Implant After Removal of a Mucocele Developing After Orbital Fracture Repair.

A few mucoceles developing secondary to facial bone fractures have been reported. Mucocele formation is thought to be attributable to displacement of the respiratory mucosa with obstruction of the sinus opening, especially if untreated. Accurate diagnosis and management are required; a growing mucocele will gradually destroy adjacent bony structures and cause irreversible complications. The authors describe a patient who presented with diplopia and mild discomfort when gazing upward. She had undergone reconstruction of medial and inferior orbital fractures 20 years previously. The patient was diagnosed with a mucocele developing after orbital fracture repair. The patient underwent mucocele removal and orbital reconstruction using a polyetheretherketone patient-specific implant. In a patient with orbital symptoms but without acute trauma, a mucocele should be among the differential diagnoses if history-taking reveals past orbital trauma and surgery. A polyetheretherketone patient-specific implant was effective for orbital reconstruction after mucocele removal.

Superficial mucoceles in cancer patients: a retrospective series from a Stomatology unit.

BACKGROUND: The aim of this study is to relate all the superficial mucoceles found in a cancer center, described the association with oncological conditions, and discuss its etiology and pathology that we found in the past few years. MATERIAL AND METHODS: Sixteen cases of superficial mucocele were retrieved from the patients' records of the Stomatology Department of the A. C. Camargo Cancer Center, São Paulo, Brazil, and demographic and clinical data were collected from electronic medical records. RESULTS: There were 16 patients, 8 patients were men and 8 women, with ages varying from 26 to 70 years old. Superficial mucoceles were observed in patients submitted to head and neck radiotherapy (n=6), graft versus host disease (n=4), one associated with oral mucositis related to allogenic bone marrow stem cells transplantation (n=1), systemic lupus (n=1), Sjögren's syndrome (n=1), oral lichenoid lesion associated with pembrolizumab (n=1) and no local or systemic inflammatory associated found (n=2). CONCLUSIONS: This study reports a series of superficial mucoceles from a single stomatology unit. Most patients had superficial mucoceles secondary to head and neck radiotherapy and graft versus host diseases. However, two patients (12.5%) had mucoceles related to systemic inflammatory conditions (Sjögren's Syndrome and Systemic Lupus).

Mucocele: a rare complication following stapled haemorrhoidopexy.

BACKGROUND: Stapled haemorrhoidopexy (SH) has resulted in a unique collection of procedural complications with postoperative mucocele a particularly rare example. This study is designed to comprehensively describe the characteristics of rectal mucocele and discuss its pathogenesis following SH surgery. METHODS: A database of patients presenting with a rectal mucocele following an SH procedure was established and studied retrospectively. RESULTS: Seven patients (5 males; median age 32 years, range 20-75 years) were identified. All patients complained of variable anal discomfort with 5/7 presenting with inconstant anal pain, 2 with de novo evacuatory difficulty. These cases appeared at a median time of 6 months (range 2-84 months) after SH surgery. CONCLUSION: Rectal Mucocele develops when mucosal fragments become embedded and isolated under the mucosa. It is a preventable complication of SH surgery by ensuring correct purse string placement prior to stapled haemorrhoid excision.

Destructive Frontonasal Mucocele Following Facial Trauma and Surgery.

ABSTRACT: Mucoceles are fluid filled cysts with numerous etiologies that can erode bone and if left untreated, can lead to infraorbital and intracranial complications. With limited cases published in the medical literature, our patient with a frontonasal mucocele expanding from the frontal sinus to the nasal dorsum with erosion of the nasal bones and upper lateral cartilages, provides an opportunity for evidence-based diagnosis and treatment. We present a 24-year-old female with a nasal mass destroying numerous nasal structures. Three surgical approaches were considered: open rhinoplasty, bicoronal approach, and Lynch excision; the latter executed with subsequent total nasal reconstruction. Bone, septal cartilage, and temporalis fascia were utilized to provide structural support and a posterior nasal septal flap was incorporated to maintain a blood supply. integrity of nasal structure and cosmesis as well as recurrence of disease were monitored during postoperative visits.

Postoperative ethmoid sinus mucoceles: Late complication of endoscopic ethmoidectomy and MWA management in outpatient.

OBJECTIVE: The aim of this study was to investigate the feasibility of intranasal endoscopic microwave ablation (MWA) on the management of postoperative ethmoid sinus mucoceles. METHODS AND MATERIALS: The patients with postoperative ethmoid sinus mucoceles were ablated through intranasal endoscopic MWA. Postoperative pain intensity was measured via visual analogue scale (VAS), post-operative complications were recorded. RESULTS: Of the 26 patients with unilateral postoperative ethmoid sinus mucoceles, the mucoceles were diagnosed 3 to 11 years with average time of time of 6.9 ± 2.7 years after endoscopic ethmoidectomy. The ipsilateral middle turbinate was present and intact in 24 patients and partially resected during the original surgery in the remaining 2. There were adhesions in the middle meatus in one case. All 26 patients were successfully treated with the intranasal endoscopic ablation technique in outpatient. The ablation time was 6 to 11 min, with an average duration of 6.84 ± 1.27 min. The mean VAS pain score was 2.41 ± 1.22. There were no perioperative complications reported in this series. No evidence of recurrence was observed in any patients during follow-up periods. CONCLUSIONS: The present study demonstrates the safety and efficacy of intranasal endoscopic MWA in the office. The procedure is well tolerated by patients with low complication rates. Thus, it is alternative to conventional endonasal endoscopic marsupialization for treatment of postsurgical ethmoid sinus mucoceles.

Paranasal mucoceles in children with cystic fibrosis: Management of a not so rare clinical condition.

PURPOSE: Paranasal mucocele (PM) is reported as a complication in children with cystic fibrosis (CF) in up to 4% of patients. The objective of this study was to identify PMs in the personal large series of children with CF and to assess their diagnosis and treatment. MATERIAL AND METHODS: Medical records of children with CF and PM who were admitted and treated by means of endoscopic nasal surgery between 2004 and 2020 were retrospectively reviewed. RESULTS: Thirty-four patients were included in the study (mean age 7.7 years). CT scan of sinuses showed a total of 53 PMs. Nasal endoscopic findings suggestive for PM were present in almost 80% of patients. PMs were located in the maxillary, ethmoid, and sphenoid sinuses in 29/34 (85.3%, bilateral in 17 cases), 4/34 (11.8%) and 1/34 (2.9%) patients, respectively. Marsupialization of PMs was performed in all patients using an endoscopic transnasal approach. No complications were observed. Resolution of symptoms and normalization of the endoscopic nasal picture was evident in all patients. After a mean follow-up of 85 months, no recurrences were observed. CONCLUSIONS: To the best of our knowledge, this is the largest series of CF patients with PMs. Even if not frequently reported in the literature, PMs should not be considered an uncommon finding in patients affected by CF. Routine nasal endoscopy is mandatory to favor early diagnosis. Endoscopic transnasal marsupialization represents the gold standard of care for patients with CF and PM(s).

Orbital and Eyelid Inflammation With "Muciphages" and Extravasated Mucin From an Ethmoido-orbital Mucocele.

A 22-year-old woman presented with an acute compressive optic neuropathy due to a ruptured ethmoido-orbital mucocele. She underwent urgent orbital decompression and drainage of the mucocele via an endoscopic approach. Postoperatively, her course was complicated by an orbital compartment syndrome supervened, exhibiting severe eyelid edema caused by infiltration with mucin and mucin-containing macrophages ("muciphages"). Biopsy of the eyelid showed infiltration with "muciphages," macrophages laden with extravasated mucinous material. This is the first report that documents the clinical and histopathologic course of orbital inflammation following mucocele extravasation into the orbit and eyelids.

The anatomical basis and rational for the transoral approach during the surgical excision of the sublingual salivary gland for the management of plunging ranula.

PURPOSE: The aim of this study was to illustrate and confirm that the complete intraoral excision of the sublingual gland alone, is anatomically the most rational approach, for the management of plunging ranula. MATERIAL AND METHODS: We retrospectively reviewed clinical charts of diagnosed HIV-infected patients presenting with plunging ranula. The intraoral approach was used for the complete excision of the sublingual gland with evacuation of the pseudocystic content only. Neither extra oral approach, nor ranula dissection / drainage was performed. The surgical procedure was performed using local anesthesia. Pre- and postoperative MRI-scan investigations were recorded. Histological reports were documented to confirm the diagnosis of oral mucocele. Patients were clinically monitored. RESULTS: We identified 90 adults presenting with oral mucocele, type ranula. Seventy (77%) of them were diagnosed with HIV infection. Plunging ranula was recorded in 35 (50%) patients from the latter group. The study enrolled 11 operated patients whose files contained useable data, including an acceptable follow-up period. The postoperative follow-up period ranged from three to 15 months. The clinical and postoperative MRI-scans of operated patients demonstrated satisfactory results. There were neither postoperative complications nor recurrence of ranula reported. CONCLUSION: The location of the sublingual gland in the floor of the mouth coupled with the physio-pathogenesis of the plunging ranula, makes the transoral complete excision of the offending gland, with the intraoral evacuation of the pseudocyst, anatomically the most rational approach for plunging ranula management. There is no need for cervical approach, ranula dissection and/or postoperative placement of drainage.

Hypohidrotic ectodermal dysplasia: a case report.

Hypohidrotic ectodermal dysplasia is a common variation of ectodermal dysplasia, characterized by hypohidrosis (or anhidrosis), hypotrichosis, hypodontia, and other distinct facial features. Furthermore, ocular tissues of ectodermal origin may also be affected in this disease. The most common ocular manifestations of hypohidrotic ectodermal dysplasia are dry eye, madarosis, alterations in the meibomian glands, abnormalities in the nasolacrimal duct, and infantile glaucoma. Herein, author reports a case of hypohidrotic ectodermal dysplasia in a 12-year-old Indian boy with dry eye and lacrimal sac mucocele.

Multiple superficial oral mucoceles after Mycoplasma-induced mucositis.

Oral mucoceles are lesions arising mainly from the minor salivary glands and are thought to occur after excretory duct trauma. We report a case of multiple superficial oral mucoceles on a child's labial mucosa after Mycoplasma pneumoniae mucositis. Mucoceles can mimic persistent or recurrent stomatitis and lead to potential errors in management.

Sphenoid Sinus Mucocele Caused by Complications After Transsphenoidal Pituitary Surgery.

OBJECTIVE: The purpose of this study was to review the clinical characteristics, treatment methods, and surgical outcomes of sphenoid sinus mucocele after transsphenoidal pituitary surgery. PATIENTS AND METHODS: A total of 404 patients who underwent transsphenoidal pituitary surgery between January 2010 and December 2016 were identified. Among them, 5 patients with sphenoid sinus mucocele were included in this study. In our hospital, a single-nostril endonasal endoscopic wide sphenoidotomy is routinely used for pituitary tumor surgery. RESULTS: The occurrence rate of sphenoid sinus mucocele was 1.2% (5/404). Of the 5 patients, 2 were males and 3 were females. Four lesions (80.0%) were located in the right sphenoid sinus and 1 lesion (20.0%) was located in the left sphenoid sinus. Endoscopic marsupialization for sphenoid sinus mucocele was performed under local anesthesia in all patients. There were no major complications resulting from the surgical intervention, and there was no recurrence at the time of the last follow-up. CONCLUSION: Sphenoid sinus mucocele after endonasal transsphenoidal pituitary surgery is an extremely rare complication. Nasal endoscopy and MRI are useful for diagnosing this lesion. Endoscopic marsupialization is a safe and effective procedure for sphenoid sinus mucocele after endonasal transsphenoidal pituitary surgery.

Radiation-related superficial oral mucoceles: An under-recognized acute toxicity in head and neck cancer patients.

BACKGROUND: Acute toxicity is usually defined as adverse changes occurring immediately or a short time after the start of oncological treatment. MATERIAL AND METHODS: Cross-sectional retrospective study performed with head and neck cancer patients who underwent radiotherapy from 2013 to 2016. RESULTS: Ten (1.2%) patients developed SOMs during radiotherapy, most (80%) of which were men with a mean age of 59.5 years at diagnosis. SOMs mainly affected the floor of the mouth (60%) between the fourth and the sixth weeks of radiation therapy. All lesions were asymptomatic and spontaneously ruptured approximately 9 days after diagnosis. CONCLUSIONS: Although rare, SOMs may be regarded as an acute oral toxicity of head and neck radiotherapy.

Paranasal Sinus Mucocele as a Late Complication of Dacryocystorhinostomy.

A 50-year-old female presented with a slowly enlarging painless mass of the right medial canthus. The past surgical history is significant for external dacryocystorhinostomy for acquired nasolacrimal duct obstruction 10 years prior and subsequent endoscopic and external revisions. Imaging revealed a large fronto-ethmoidal sinus mucocele extending into the right medial orbit. On surgical exploration, the right middle turbinate was found to have lateralized, obstructing sinus outflow. The mucocele was evacuated and ethmoidectomy and middle turbinectomy were performed. The patient did well postoperatively without recurrence at 6 months of follow-up. Sinus mucocele formation is a rare, late complication of lacrimal surgery.

Frontal Sinus Mucocele Formation as a Late Complication of External Dacrocystorhinostomy.

Two cases of frontal sinus mucocele post external approach dacrocystorhinostomy (DCR) surgery are reported. The possible anatomical causes of this condition are discussed and in particular, attention is drawn to the consideration of frontal sinus mucocele in patients presenting with frontal sinus symptoms post-DCR surgery.

Postoperative long-term morbidity of extended endoscopic maxillectomy for inverted papilloma.

BACKGROUND: Extended endoscopic maxillectomy (Sturmann-Canfield procedure) allows full visualization of the maxillary sinus by sectioning the lacrimal duct and removing the medial part of the anterior maxillary wall. The aim of this study is to evaluate the morbidity of Sturmann-Canfield procedure in patients treated for inverted papilloma. METHODOLOGY: The clinical records of all patients treated with a Sturmann-Canfield procedure for inverted papilloma from October 2000 to September 2015 at two teaching hospitals were reviewed. All patients were evaluated by nasal endoscopy and lacrimal system patency was assessed. Pre-maxillary cutaneous sensitivity was tested with a Semmes-Weinstein aesthesiometer and thermic stimulation. The SNOT-22 questionnaire was administered. Patients were also asked to report any other post-surgical complaints. RESULTS: Fifty-nine patients were identified. Mean follow-up after surgery was 66.3 months. Mean SNOT-22 score was 5.94 (range 0-20); the majority of patients (86%) had a SNOT-22 symptom score of 3 or lower. Mucocoele occurred in 3 (5%) cases. Lacrimal pathway obstruction was observed in 7 (12%) patients. Fourteen (24%) patients complained of paraesthesia in the malar area; hypoesthesia was present in only 5 (8%) cases. Hypoesthesia in the region innervated by the anterior superior alveolar nerve was detected in 17 (29%) patients. One patient reported a slight depression of paralateronasal soft tissues. CONCLUSIONS: Although nasal function outcomes and the results from SNOT-22 questionnaires were favourable, a high rate of neurologic and lacrimal complications was observed. Potential morbidity of the intervention, including the possibility of negative aesthetic sequelae, should be discussed during preoperative counselling.

Endoscopic-Assisted Removal of a Rare Mucocele Complicating From Alloplastic Medial Orbital Fracture Reconstruction.

Orbital wall fracture reconstruction is usually recommended to prevent subsequent functional and esthetic complications. Mucocele development following such injuries or its management is recognized but rare sequelae. When they occur, they represent a diagnostic and management dilemma. The authors described a patient with orbital and ethmoidal mucocele. A 62-year-old female patient presented with progressive left exophthalmos 1 year following titanium mesh reconstruction of a medial orbital wall fracture. Computed tomography and magnetic resonance imaging demonstrated an encysted lesion encasing the mesh plate in the left orbit and extending into the ethmoidal sinus. The patient is treated surgically through endoscopic-assisted approach with complete removal of the lesion and lacrimal duct stenting. The patient improved immediately after surgery.

The Medial Femoral Condyle Corticoperiosteal Free Flap for Frontal Sinus Reconstruction.

Although the medial femoral condyle has been used for reconstruction in various areas of the body, to the authors' knowledge it has not been used for frontal sinus reconstruction. The authors describe a novel approach to a complex patient using the medial femoral condyle cortiocoperiosteal free flap to reconstruct an anterior frontal sinus defect in conjunction with a recalcitrant mucocele.

The authors describe a clinical case of pyocele of the frontal sinus in the patient presenting with polypous pansinisitis and pronouncd hypertrophy of the frontal sinuses with special reference to the specific features of diagnostics and surgical strategy for the treatment of this condition.

Superficial Mucocele of the Ventral Tongue: Presentation of a Rare Case and Literature Review.

The superficial mucocele is a rare variant of the common mucocele and noted microscopically by subepithelial pools of mucin. To increase the understanding of oral superficial mucoceles, a database was created from the demographics of case reports and case series from a PubMed search. At least 200 patients with superficial mucoceles have been described in the English-language literature, 82 of whom had biopsy-proven lesions; additional clinical information was available for 39 of these 82 patients. Compiled data suggest superficial mucoceles offered phenotypic distinctions from the common mucocele because they were more apt to occur in middle-aged women, often on the soft palate and buccal mucosa. Affected patients frequently had multiple lesions that were smaller than 3 mm and nearly 50% of patients developed recurrence. This report also describes the first histopathologically confirmed case of a superficial mucocele arising on the ventral tongue in a 22-year-old man. It is speculated that the glossal lesion might have developed from long-term impingement from exposed metal barbs from an orthodontic splint. Persistent lesions or atypical presentations underscore the need for histopathologic examination.
