A large thyroglossal duct cyst and its management: a case report.

Thyroglossal duct cysts (TGDC) are congenital neck cysts, formed as a result of the failure of the thyroglossal duct to involute during embryogenesis and their mean size is 1.5-2.4 cm. We present a case of a 44-year-old male who presented with a history of a large anterior neck mass measuring 8.7x6x6.4 cm and causing dysphagia and mild dyspnea. After being mistaken for a goiter, a clinical diagnosis of TGDC was made based on history, clinical and radiographic findings. The patient was treated with Sistrunk's procedure. No recurrence was noted on follow-up. Thyroglossal duct cysts are generally well-defined small lesions, but even bigger ones are not linked with severe symptomatology. The larger size at presentation may increase the list of potential diagnoses and lead to diagnostic dilemmas. Every effort should be made to rule out malignancy before surgery. Sistrunk's procedure with dissection of the posterior hyoid space should be the standard of care.

Do smoking and human papilloma virus have a synergistic role in the development of head and neck cancer? A systematic review and meta-analysis.

PURPOSE: Head and neck squamous cell carcinoma (HNSCC), arising from the squamous epithelium, is the most common head and neck cancer (HNC). Smoking and alcohol are well known risk factors for HNSCC, while some high-risk human papilloma virus (HPV) subtypes were specifically identified as a high-risk factors for developing oropharyngeal squamous cell carcinoma (OPSCC). In this study, we have conducted a systematic review and meta-analysis in order to investigate the possible synergistic role of smoking and HPV in the development of HNSCC. METHODS: We conducted a systematic search in two online databases PubMed and Cochrane Library, searching for studies published between 2010-2018. Sixteen studies met the inclusion criteria; a total of 2161 patients were included, comprising 1470 HPV-negative and 691 HPV-positive, respectively. RESULTS: The number of smokers between HPV-positive HNSCC patients (group A) and HPV-negative HNSCC patients (group B) was compared. We have found that smokers in HPV-positive group were statistically significantly less than smokers in HPV-negative group (OR=0.33 with 95% CI 0.18, 0.61). The test for overall effect was Z =3.61 (p=0.0003). CONCLUSION: Smoking is less common in HPV positive group than in HPV negative group, and so probably smoking does not play a major role in the pathogenesis of HPV-positive HNSCC as in the pathogenesis of HPV-negative HNSCC.

Current Treatment Options for Patulous Eustachian Tube: A Review of the Literature.

OBJECTIVE: Patulous Eustachian tube (PET) is a clinical condition that is associated with troublesome aural symptoms and is difficult to be treated successfully. The purpose of this review is to examine the published literature regarding the therapeutic value of the current treatment options for PET. METHODS: We searched Web of Science, PubMed and Medline from 1999 to 2019. The search focused on papers concerning the clinical evaluation of treatment methods in PET patients. Statistical techniques were not used. RESULTS: Prospective and retrospective case series were the types of trials available for review. We included 28 articles that evaluated the efficacy of various conservative and surgical therapeutic options. The recovery rates ranged from 50% to 100%. In most studies the assessment of efficacy was based on the subjective improvement of patient symptoms as there is no validated outcome tool available. No severe adverse events were observed in any study. CONCLUSION: On the basis of the available literature, it seems that conservative treatments can be considered as a primary therapeutic option for PET. Concerning the surgical interventions they seem to be a safe and valuable solution in patients with refractory disease. Finally, given the low level of evidence, prospective case-control studies with long follow-up and robust setting looking into the therapeutic approach of PET are required. The need for establishment of standard criteria of PET recovery should be underlined.

Otomycosis With Tympanic Membrane Perforation: A Review of the Literature.

OBJECTIVE: The purpose of the present study was to assess the rate of tympanic membrane perforation in patients with otomycosis and to discuss the literature regarding the difficulties in managing this condition. DATA SOURCES: Literature review from 1999 to 2019, Web of Science, PubMed, and Medline. STUDY SELECTION: We searched for eligible articles concerning the clinical entity of tympanic membrane perforation secondary to otomycosis. Case series and clinical trials were the types of articles included for this review. DATA EXTRACTION: All the articles described in the study selection were used for this review. DATA SYNTHESIS: Statistical techniques were not used. CONCLUSION: Based on the available literature, it seems that tympanic membrane perforation secondary to otomycosis is not uncommon. The presence of this complication is associated with 2 problems: Antimycotic solutions are irritant to middle ear and may be ototoxic to the cochlea. Although most cases of fungus caused tympanic membrane (TM) perforation resolve with proper medical treatment, in a few patients a tympanoplasty may be required.

Pott's puffy tumor in children: A review of the literature.

OBJECTIVES: Pott's puffy tumor (PTT) is a frontal subperiosteal abscess associated with underlying frontal osteomyelitis. The purpose of the present study was to assess the rate of intracranial involvement in pediatric and adolescent patients with PPT and to discuss the diagnostic workup and the therapeutic features of this pathology. METHODS: We searched Web of Science, PubMed and MEDLINE from 1998 to 2018. The search focused on papers concerning the diagnostic procedure and therapeutic management of PTT. Statistical techniques were not used. RESULTS: We included 53 articles that described 92 pediatric and adolescent patients with PPT. The overall rate of intracranial complications was found to be 72%. Most authors used computed tomography for the diagnosis of PTT and its complications, either alone or in combination with magnetic resonance imaging. In 50% of cases, an endoscopic endonasal approach is used for the management of the underlying acute or chronic sinusitis. CONCLUSIONS: On the basis of the available literature, it seems that the incidence rate of intracranial involvement in patients with PPT is quite high. Early diagnosis using the appropriate imaging raise the possibility of good recovery. Concerning the therapy of PTT, endoscopic sinus surgery could be considered as a valuable technique. The vast majority of patients treated appropriately recover without long-term neurologic complications and sequelae. LEVEL OF EVIDENCE: 4 Laryngoscope, 130:225-231, 2020.

Mastoid Obliteration with Synthetic Materials: A Review of the Literature.

Canal wall down mastoidectomy is a surgical technique used for the eradication of middle ear disease. The remaining large mastoid bowl is associated with a number of issues; one of the main techniques that have been developed in order to avoid such problems is the obliteration of the mastoid cavity. The materials used for this reason are either biological or synthetic. The purpose of this survey is to review the published literature related to the therapeutic value of mastoid obliteration with synthetic materials. We searched Web of Science, PubMed, and MEDLINE from 2008 to 2018 using the criteria mastoid obliteration, canal wall down mastoidectomy, chronic otitis media, and cholesteatoma. The search focused on papers concerning the mastoid obliteration with synthetic material, as we focused on looking for outcomes and reported complications. Out of a total of 244 citations, 15 articles were identified, where patients underwent mastoid obliteration with synthetic materials. Most authors used bioactive glass as a filler material. Mastoid obliteration resulted in a decrease in the complications associated with the open mastoid cavity. On the basis of the available limited literature, it seems that mastoid obliteration with synthetic materials is a valuable and safe surgical technique for patients who undergo canal wall down mastoidectomy. The bioactive glass appears to be the most reliable synthetic material.

Granular cell (Abrikossoff) tumor in the head and neck: A series of 5 cases.

We evaluated a series of 5 patients-3 men and 2 women, aged 39 to 70 years (mean: 54.4)-with a granular cell tumor (GCT) of the head and neck in an effort to better define the clinical presentation, imaging characteristics, and surgical management of this type of tumor. In all cases, the diagnosis was established by pathologic analysis. There were 2 cases of laryngeal GCT and 1 case each of GCT arising in the nostril, hypopharynx, and the tongue base. The clinical findings were variable, depending on the location and extent of each lesion. Four of these patients underwent endoscopic examination, and in 2 cases computed tomography was performed. Treatment included wide surgical excision of the lesion in all cases. Otolaryngologists should be familiar with this unusual tumor. Although an accurate preoperative diagnosis is extremely difficult to make, appropriate therapeutic intervention is associated with a cure rate that is quite high.

Anaplastic carcinoma in submandibular region: A diagnostic dilemma.

INTRODUCTION: Thyroid carcinoma arising in an extrathyroid area is a rare entity. PRESENTATION OF CASE: We report a case of anaplastic carcinoma in the submandibular region occurring in a 70-year-old woman. DISCUSSION: The location of the mass along with no evidence of primary tumor at the orthotopic thyroid gland posed a diagnostic dilemma: was this an ectopic thyroid carcinoma or rather a case of occult differentiated thyroid carcinoma metastasis that transformed to anaplastic carcinoma? Based on the histopathological findings we concluded that the tumor arised in ectopic thyroid tissue. Although the mass was completely resected, the patient died 10 months after diagnosis due to pulmonary metastases. CONCLUSION: Conclusively, the possibility of ectopic thyroid tissue, with or without disease, should be considered in cases of a mass in the submandibular region.
