Outcomes of Septal Perforation Repair With Concurrent Endoscopic Sinus Surgery.

OBJECTIVE: This study reviews a cohort of patients in whom septal perforation repair was performed concurrently with endoscopic sinus surgery. We present an endonasal perforation repair technique using bilateral mucosal flaps with an autogenous interposition graft. Intraoperative and postoperative management of the combined surgical patient is discussed and perforation closure outcomes are reported. STUDY DESIGN: Case series. SETTING: Tertiary care center. METHODS: In this institutional review board-approved retrospective chart review, adult patients who underwent concurrent bilateral mucosal flap septal perforation repair and endoscopic sinus surgery from March 1992 to March 2020 were identified. Data on demographics, clinical presentations, perforation size, surgical techniques, and outcomes were extracted and analyzed for patients with a minimum of 3 months of follow-up. RESULTS: Fifty-six patients met study inclusion criteria. Nasal obstruction/congestion was the most frequent symptom reported (80.4%), followed by crusting and epistaxis. Mean perforation size measured at the time of surgery was 14.7 (range, 3-41) mm in length by 9.3 (range, 2-23) mm in height. Temporalis fascia was the most frequent (57.9%) interposition graft material used. Complete perforation closure at the time of the last follow-up was noted in 51 (91.1%) patients. Only 1 failure was noted in the last 48 attempted repairs. CONCLUSION: Patients with a perforated septum may have coexistent chronic sinusitis. The feasibility of attempting concurrent sinus surgery and perforation repair has been questioned. Our review demonstrates a high perforation closure rate when a bilateral mucosal flap procedure is performed after sinus surgery is performed at the same setting.

Tongue Tied after Shoulder Surgery: A Case Series and Literature Review.

This article presents three cases of cranial nerve palsy following shoulder surgery with general anesthesia in the beach chair position. All patients underwent preoperative ultrasound-guided interscalene nerve block. Two cases of postoperative hypoglossal and one case of combined hypoglossal and recurrent laryngeal nerve palsies (Tapia's syndrome) were identified. Through this case series, we provide a literature review identifying postoperative cranial nerve palsies in addition to the discussion of possible etiologies. We suggest that intraoperative patient positioning and/or airway instrumentation is most likely causative. We conclude that the beach chair position is a risk factor for postoperative hypoglossal nerve palsy and Tapia's syndrome.

Contemporary applications of frontal sinus trephination: A systematic review of the literature.

Our objective was to perform a systematic review of the literature on contemporary indications and outcomes for frontal sinus trephination and present an illustrative case of an endoscopically assisted repair of a subcutaneous frontal sinus fistula by trephination technique. PubMed and Ovid databases were used as data sources. A systematic review of the English literature was completed to review reports of frontal trephination from 1980 to 2014. Articles meeting inclusion criteria for inflammatory and noninflammatory indications were reviewed. Articles were systematically reviewed and graded by evidence-based medicine level. An illustrative case from our institution is then presented. The systematic review identified 2,621 published studies. Thirty-eight studies were identified for inclusion. The indications, techniques, outcomes, safety, and complications were reviewed for noninflammatory and inflammatory conditions. There were 32 retrospective case series, reports, or cohort studies (level 4), four systematic reviews (level 3), one prospective analysis (level 3), and one meta-analysis (level 2). Due to the heterogeneity of study cases and inclusion criteria, a meta-analysis was not feasible. We also present a novel closure of an anterior skull base defect resulting in a subcutaneous fistula with use of a frontal trephination approach. The frontal sinus trephination should not be regarded as a procedure of the past, as it useful in the armamentarium of the modern sinus and skull base surgeon. This approach provides access for instrumentation for hard-to-reach frontal sinus disease either purely through a trephination approach or as a supplementation to the transnasal endoscopic approach. Evidence supporting frontal sinus trephination is of levels 2, 3, and 4. Level of evidence: NA.

Infected cochlear implant after large-volume nasal irrigation.

OBJECTIVE: A patient with a well-healed, functional cochlear implant (CI) experienced a CI and mastoid infection shortly after initiating large-volume nasal irrigations after sinus surgery. The goal of this report is to bring attention to a rare complication and to question if large-volume nasal irrigation is safe in CI recipients. PATIENTS: Single patient at a tertiary care hospital. INTERVENTIONS: A CI recipient began using large-volume nasal irrigations with saline and budesonide after undergoing sinus surgery. MAIN OUTCOME MEASURES: CI infection and mastoiditis. RESULTS: Two weeks after starting nasal irrigations, the patient presented with mastoiditis and CI infection. Mastoid and intranasal middle meatal cultures both grew Group A streptococcus. CONCLUSION: Large-volume nasal irrigations may be related to our patient's CI infection, ultimately leading to explantation. Though a causal relationship cannot be definitively proven, awareness of this potential safety issue should be disseminated.

Updates in reconstruction of skull base defects.

PURPOSE OF REVIEW: Skull base surgery has undergone a fundamental transformation with the development and rapid adoption of endoscopic endonasal expanded approaches. Defects created from these newer approaches have necessitated an evolution of novel reconstructive techniques, which are reviewed here. RECENT FINDINGS: New reconstructive techniques continue to be developed for repairing surgical defects from endoscopic endonasal skull base resections. Improvisations also allow well known flaps to be used in these approaches. Long term outcomes from repair using some of these techniques are now becoming available. SUMMARY: Endoscopic resection of previously unapproachable skull base lesions has become possible with advancements in technology, as well as reconstructive methods. These newer techniques may offer improved outcomes and lower morbidity over conventional surgery.

Perplexing lesions of the sinonasal cavity and skull base: IgG4-related and similar inflammatory diseases.

OBJECTIVE: IgG4-related disease (IgG4RD) causing sinonasal and skull base pathology is uncommonly described. We present a series of suspected IgG4RD patients, with a pertinent review of the literature to highlight diagnostic challenges. STUDY DESIGN: Case series. SETTING: Academic tertiary care center. SUBJECTS AND METHODS: Case series of patients with IgG4RD or suspected IgG4RD involving the sinonasal cavity and skull base. RESULTS: We present 4 patients with atypical sinonasal and/or skull base disease who were noted to have IgG4-positive plasma cell infiltration on immunohistochemistry of biopsy specimens. IgG4RD, a recently described entity affecting multiple organs, is characterized by lymphoplasmacytic infiltration and often elevated serum IgG4. IgG4RD can masquerade as malignancy or infection but responds to glucocorticosteroid and immunosuppressant therapy. IgG4RD has been infrequently reported presenting as sinonasal or skull base lesions, and definitive diagnostic criteria for these regions are not established. In our series, IgG4RD was suspected in all 4 patients, but only 1 met all current criteria for definitive diagnosis. All 4 patients, however, responded to corticosteroid therapy, and 1 was placed on long-term azathioprine. CONCLUSION: IgG4RD is rarely described in the sinonasal cavity and skull base, and specific diagnostic criteria for such disease have not been defined. We present a series of patients with IgG4-positive plasma cell inflammatory pathology who were suspected to have IgG4RD. Our series highlights diagnostic challenges associated with these patients. Tumefactive and destructive sinonasal-skull base lesions with a plasma cell-rich infiltrate should incite suspicion of IgG4RD, and immunohistochemistry for IgG4-positive plasma cells should be performed.

Laryngeal hibernoma: case series of a rare tumor.

BACKGROUND: Hibernomas are rare, benign tumors of brown adipose tissue uncommonly found in the head and neck. METHODS: A review of the English-language literature was conducted for this study. We present a series of 2 laryngeal hibernomas treated with transoral laser microsurgical resection at a tertiary referral center over a period of 18 years. RESULTS: Only 2 cases of laryngeal hibernoma have been previously described in the literature. Two additional cases were encountered at our institution. Preoperative imaging demonstrated a well-circumscribed neoplasm with fat density compatible with lipoma, but internal heterogeneity and vascularity seen in the context of liposarcoma. Transoral laser microsurgical resection was successfully performed in each case. CONCLUSION: Despite unique radiographic features, hibernomas are difficult to distinguish from well-differentiated liposarcoma and lipoma variants without pathologic correlation. Complete surgical resection is indicated. In our experience, transoral laser microsurgical excision of laryngeal hibernomas is a safe, effective treatment modality with little associated morbidity.

Sinonasal phosphaturic mesenchymal tumor: Case report and systematic review.

We report a case of sinonasal phosphaturic mesenchymal tumor (PMT) and conduct a systematic review of the literature to highlight a unique paraneoplastic syndrome associated with PMT. We used English language publications from Medline and Cochrane databases (1970-2013) as data sources. A systematic review of the literature was conducted. All reported cases of head and neck PMTs were included. The presence or absence of the associated paraneoplastic syndrome was noted. We found 33 cases of PMT in the head and neck reported in the literature, 17 of which occurred in the sinonasal area. Approximately 5% of all PMTs are located in the head and neck. Just greater than half are concentrated in the sinonasal area, and the remaining involve various bony and soft tissue structures of the head and neck. PMT is sometimes associated with a paraneoplastic syndrome of tumor-induced (oncogenic) osteomalacia (TIO) causing bone pain, muscle weakness, and pathologic fractures. We present the 18th reported case of sinonasal PMT. A smooth mucosa-covered midline intraseptal mass filling the posterior nasal cavity with destruction and erosion of the skull base was found in an adult male. The patient underwent successful endoscopic resection with wide negative margins and is without recurrence at 24-month follow-up. PMT is a benign, locally aggressive tumor with rare malignant transformation. Knowledge of the bony invasion and destruction caused by this tumor is essential in planning surgical resection with wide negative margins. Familiarity with the associated TIO is essential to investigate for and manage any associated bony morbidity.

Abducens palsy after lumbar drain placement: a rare complication in endoscopic skull base surgery.

OBJECTIVES/HYPOTHESIS: To study reports of abducens nerve palsy following dural puncture procedures and to discuss possible etiologic theories, treatment, and prognosis. STUDY DESIGN: Systematic review of peer-reviewed literature. METHODS: A systematic literature review was conducted (PubMed, 1950 to September 2011) for cases of sixth cranial nerve palsy following dural puncture procedures. RESULTS: We report a case of abducens nerve palsy following lumbar drain placement for endoscopic trans-sphenoidal pituitary macroadenoma resection. Sixth nerve palsy was noted immediately after surgery. Postoperative computed tomography and magnetic resonance imaging revealed no injury to the nerve or surrounding structures. A systematic literature review conducted for cases of abducens nerve palsy following dural puncture procedures found 22 studies (17 case reports and five case series). Twenty-eight patients with temporary or permanent abducens nerve palsy were reported. Procedures included diagnostic lumbar puncture, spinal anesthesia, intrathecal catheterization, and shunting. Traction and local ischemia due to intracranial hypotension at the petroclival junction were proposed as causes of palsy. CONCLUSIONS: Lumbar puncture procedures carry a rare risk of abducens nerve palsy from ischemic or traction injury. Routine use of lumbar drain during endoscopic skull base surgery is not without risk, and need for its placement should be carefully determined. Knowledge of such rare complications is helpful in risk-benefit analysis as endoscopic skull base techniques gain popularity.

Update on the management of chronic rhinosinusitis.

Chronic rhinosinusitis (CRS) is a common disorder characterized by mucosal inflammation of the nose and paranasal sinuses with sinonasal symptoms persisting for greater than 12 weeks. The etiology of CRS is incompletely understood. Current understanding supports inflammation, rather than infection, as the dominant etiologic factor. CRS significantly impacts patients' quality of life and health care expenditure. There is no standard management of CRS. Treatment strategies differ based on divergent etiologies of the various CRS subclasses. Both systemic and topical agents are used. These interventions differ in CRS with nasal polyposis (CRSwNP), CRS without nasal polyposis (CRSsNP) and specific situations such as allergic fungal rhinosinusitis or aspirin-exacerbated respiratory disease. Antibiotics are the most commonly prescribed medication for CRS, but their role in management is not strongly supported by high-level studies. This paper provides a succinct review of the evidence supporting or refuting common therapeutic agents in the management of CRS. Novel and emerging strategies will also be discussed.

Right-sided pyriform sinus fistula: a case report and review of the literature.

Objectives. Pyriform sinus fistulae arise from disturbances in the development of the fetal third and fourth branchial pouches and are predominantly found on the left side. We report the rare case of a right-sided pyriform sinus fistula presenting as a lateral neck abscess. Study Design. Case report. Methods. A 24-year-old woman presented with a two-week history of right-sided neck abscess. A fluoroscopic sinogram revealed a fistulous tract extending from the abscess to the apex of the right pyriform sinus. It was determined that the fistula was likely a third or fourth branchial remnant, a rare right-sided finding. Chemocauterization of the fistulous tract with 40% trichloroacetic acid was used to successfully treat the patient. Results. Approximately 93-97% of branchial pouch anomalies are left sided. Treatment options include surgical excision and cauterization. Conclusions. Branchial cleft cyst and pyriform sinus fistula must be considered in the diagnosis of cervical abscess in either side of the neck.
