Transpterygoid stent placement for management of a recurrent infratemporal fossa epidermoid cyst: a technical note.

ABSTRACT: Epidermoid cysts (ECs) are benign congenital cysts that typically develop from misplaced stratified squamous epithelium during neural tube closure. They are most commonly encountered in the cerebellopontine angle, the fourth ventricle, and the region of the sella turcica. Recurrence of an EC or regrowth of residual components following surgery is known to occur, but the exact incidence is not defined. Repeat surgical removal is generally considered but may be complicated by significant morbidity. We present a novel endoscopic method by which to manage a recurrent EC of the infratemporal fossa using a silastic stent through a transpterygoid approach that permits periodic drainage of recurrent cyst material in the outpatient setting with minimal morbidity.

Dermoid cyst of the infratemporal fossa: case report and review of the literature.

Project description:Background Intracranial dermoid cysts are rare tumors of congenital origin. We report a case of a large dermoid tumor arising in the infratemporal fossa (ITF) with erosion into the middle cranial fossa. After reviewing the literature, we believe this represents the first reported dermoid tumor of the ITF with extension into the middle cranial fossa. Results A 21-year-old women presented with a large cystic mass involving the left infratemporal fossa and middle cranial fossa that was discovered following a motor vehicle collision. Neurologic examination was normal. The mass was resected through a frontotemporal extradural approach with endoscopic assistance. Imaging studies, gross findings, and histopathology were consistent with a dermoid tumor. Conclusion This is the first report of a dermoid cyst arising in the ITF with extension into the middle cranial fossa. We suggest including dermoid tumor in the differential diagnosis of cystic abnormalities in this region. Complete resection of the cyst remains the preferred treatment with surgical approach guided by preoperative imaging.

Surgical Management of a Functional Paraganglioma of the Infratemporal Fossa.

Project description:Background Paragangliomas are rare neural crest tumors that can manifest in the head and neck as either functional or more commonly as nonfunctional lesions. Paragangliomas of the infratemporal fossa are exceedingly rare, with no more than a handful of documented cases. Like other tumors of this space, surgical management is challenging on account of complex anatomy and nearby critical structures. Methods A 44-year-old man presented with a right infratemporal fossa functional paraganglioma. Following preemptive embolization and autonomic pharmacotherapy, his tumor was successfully resected via a transfacial maxillary swing approach. Results This case highlights the surgical management of a functional paraganglioma of the infratemporal fossa while demonstrating the effectiveness of a transfacial maxillary swing approach for both exposure and resection. Conclusion Although this report summarizes much of the literature on paragangliomas, there is still much to uncover regarding the fundamental features and genetic etiology of these lesions.

Evolution of transmaxillary approach to tumors in pterygopalatine fossa and infratemporal fossa: anatomic simulation and clinical practice.

Project description:BackgroundThe endoscopic transnasal approach has been proven to have advantages on the removal of the tumors in pterygopalatine fossa (PPF) and infratemporal fossa (ITF). Herein, this study aimed to describe a modified approach for resection of the tumors in these areas, both in cadaveric specimen and clinical patients.MethodsThe 20 adult cadaveric specimens and five patients with tumors in PPF and ITF were enrolled in this study. For the cadaveric specimens, ten were simulated anterior transmaxillary approach and ten were performed modified endoscopic transnasal transmaxillary approach. The exposure areas were compared between two groups and main anatomic structure were measured. Surgery was operated in the five patients with tumors of PPF and ITF to verify the experience from the anatomy. Perioperative management, intraoperative findings and postoperative complications were recorded and analyzed.ResultsThe modified endoscopic transnasal transmaxillary approach provided as enough surgical exposure and high operability to the PPF and ITF as the anterior transmaxillary approach did. The diameter of maxillary artery in the PPF was 3.77 ± 0.78 mm (range: 2.06-4.82 mm), the diameter of middle meningeal artery in the ITF was 2.79 ± 0.61 mm (range: 1.54-3.78 mm). Four patients who suffered schwannoma got total removal and one of adenocystic carcinoma got subtotal removal. The main complications were facial numbness and pericoronitis of the wisdom tooth. No permanent complication was found.ConclusionsWith the widespread use of neuroendoscopy, the modified endoscopic transnasal transmaxillary approach is feasible and effective for the resection of tumors located in PPF and ITF, which has significant advantages on less trauma and complications to the patients.

Posterior deltoid-sparing approach for displaced inferior or posterior glenoid fossa fractures: technical note and case series.

Project description:Scapular surgery has usually been performed through the posterior Judet approach. This approach allows access to the entire posterior scapular body, but causes significant soft tissue damage and detaches the deltoid muscle. To date, there has been no clinical study of a deltoid-preserving approach to access the joint for displaced postero-inferior glenoid fractures (Ideberg type II or Ib). We describe an easy and less invasive approach to the postero-inferior glenoid fossa.

Arthroscopic Management of a Coracoid Fracture Associated With Acromioclavicular Dislocation: Technical Note.

Project description:Operative management of a coracoid process fracture is indicated in case of painful nonunion, displacement of more than 1 cm, or multiple disruptions of the superior shoulder suspensory complex. Several techniques have been described with open reduction of the fracture and internal fixation using cortical screws with or without additional fixation of the acromioclavicular joint. This Technical Note aims to introduce an alternative safe, minimally invasive method for arthroscopic fixation of a coracoid fracture with simultaneously reduction of the acromioclavicular joint. The described arthroscopic technique might be helpful for shoulder surgeons who want to fix the coracoid process while avoiding the disadvantages of an open approach.

Ventricular access device placement in the fourth ventricle to treat malignant fourth ventricle brain tumors: technical note.

Project description:Ventricular access devices (VADs) are commonly placed in the lateral ventricle but rarely placed in other ventricular compartments. This manuscript describes technical aspects of VAD placement into the fourth ventricle for the purpose of treating malignant posterior fossa brain tumors.As part of a pilot clinical trial to treat recurrent malignant brain tumors in children, seven patients underwent posterior fossa craniotomy and placement of a ventricular catheter under direct vision into the fourth ventricle. The catheter was placed without passing through any brain parenchyma. It was then connected to a VAD placed subcutaneously at the inferior aspect of the incision. Three of the seven patients underwent simultaneous subtotal resection of recurrent tumor located in the fourth ventricle or cerebellum, and one patient underwent simultaneous tumor biopsy. The VAD was used to administer chemotherapy (methotrexate) in five of the seven patients.Six patients had no new neurological deficits after surgery, and one patient had partial left-sided facial weakness that was attributed to resection of tumor close to the floor of the fourth ventricle. No new neurological deficits were caused by VAD placement or by methotrexate infusions into the fourth ventricle.A VAD for chemotherapy infusion can be placed safely into the fourth ventricle without damaging the brainstem or cerebellum. Attention to anatomical details specific to the fourth ventricle are important when placing a fourth ventricle VAD and when using it to administer chemotherapy.

Giant Retrorectal Epidermoid Cyst Masquerading as a Perianal Swelling.

Project description:A retrorectal epidermoid cyst is an uncommon congenital lesion that arises from the remnants of the embryonic tissues. This type of cyst is difficult to diagnose before surgery. In this study, we report a rare case of a giant retrorectal epidermoid cyst in a 30-year-old woman. Initially, the condition was diagnosed as a perianal abscess and treated with incision and drainage. Since the abscess recurred, a pelvic magnetic resonance imaging was ordered, which revealed an 8.2?cm perianal cyst with appearance not compatible with an abscess. Postsurgical histologic analysis confirmed a retrorectal epidermoid cyst. Postoperative course was uneventful, and the woman was discharged on postoperative day 3. She was doing well at 4 months of follow-up. This report suggests that retrorectal cysts should be considered in cases of recurrent perianal swellings/abscesses.

Retrieving a displaced third molar from the infratemporal fossa: case report of a minimally invasive procedure.

Project description:BackgroundThe appropriate management of postoperative complication of wisdom teeth removal is of utmost importance as it can result in legal procedures. The accidental displacement of a maxillary third molar in the infratemporal fossa (ITF), is a rare complication that can occur even with experienced surgeons. The numerous retrieval techniques reported are invasive and provide an unpredictable access. Our aim was to achieve the safe and swift retrieval of the tooth displaced to an area of such complex anatomy.Case presentationWe describe the case of a 17-year-old female patient whose right upper third molar was accidentally pushed upward to the ITF and became unreachable. Retrieval based on interventional radiology using the CT-guided placement of a bone trocar above the displaced tooth was successfully performed. The postoperative course was uneventful.ConclusionsCT scan assisted interventional radiology provides both, real-time assessment of the tooth position through image refreshment, and steady stabilization of the displaced tooth. Therefore, it allows a safe and non-traumatic retrieval with a time-efficient procedure achieved through a minimally-invasive approach with inconspicuous scaring. We believe that such a procedure is an interesting treatment option for optimal outpatient care. To our knowledge, no such case has been previously described.

Infratemporal fossa infection with inferior alveolar nerve involvement.

Project description:Abscess of the infratemporal fossa is a rare complication which can be difficult to diagnose. It occurs mostly due to dental infection, tooth extraction, fractures and/or infections involving the maxillary sinus. This condition can be life threatening if not dealt with immediately. The maxillofacial surgeon must be aware of the symptoms and clinical findings of the infection of the infratemporal fossa in order to initiate the treatment as soon as possible. In this case report, a patient with an infratemporal fossa infection presenting with an unusual symptom of inferior alveolar nerve involvement is presented.
