Use of Bichat's buccal fat pad for the sealing of orosinusal communications. A presentation of 8 cases.

2011

Objectives: To determine the efficacy of the pediculate flap with the buccal fat pad in the sealing of orosinusal communications, describe the surgical technique used, and report the main complications. Patients and method: A retrospective study was made of 8 patients seen in the Service of Oral Surgery of the University of Barcelona Dental Clinic (Spain) for the treatment of orosinusal communications between the years 2007 and 2009. In all cases a pediculate flap with the buccal fat pad was used to solve the problem. Results: All of the orosinusal communications were successfully resolved with this technique. The immediate postoperative complications were pain (37.5%), inflammation (37.5%)…

Stentgraft-Implantation for Treatment of Internal Carotid Artery Injury during Endonasal Sinus Surgery

2007

Background Damage of the internal carotid artery (ICA) is very rare but can be a dramatic complication of endonasal sinus surgery. In the literature only a few cases are reported, some of them with fatal results. Methods We present two cases with massive bleeding of the ICA caused by endonasal sinus surgery. Results In both cases bleeding could be stopped sufficiently by implanting a stentgraft. Conclusion The lumen of the artery could be preserved and no neurological deficits were observed.

Paranasal sinuses malignancies: A 12-year review of clinical characteristics

2016

Background Inadequate epidemiologic investigations of the paranasal sinuses malignancies prompted this retrospective study with special emphasis on a major group of 111 tumors. Material and Methods Clinical records of 111 patients with histologically confirmed malignant tumors of the paranasal sinuses were investigated retrospectively from April 2000 to January 2012. Collection of data included demographic information, clinical manifestations, treatment plans, and histopathology of the tumor. Results There were 69 (62.16%) male and 42 (37.83%) female patients (male-to-female ratio of 1.6:1), with a median age of 49±12.2 years (range 21 to 88 years). A high level of occurrence was noticed in…

Effect of irrigation of the nose with isotonic salt solution on adult patients with chronic paranasal sinus disease

2001

In a prospective, randomized, controlled, double-blind trial we compared the effectiveness of endonasal irrigations with Ems salt solution to that with sodium chloride solution in the treatment of adult patients with chronic paranasal sinus disease. Subjects (n = 40) were randomly allocated to treatment either with isotonic Ems salt solution or with isotonic sodium chloride solution. The treatment consisted of endonasal irrigation twice daily and additional nasal spray as required. Nasal endoscopy, plain radiography of the paranasal sinuses, olfactometry, anterior rhinomanometry, and a saccharin-clearance test were carried out on days 1 and 7. Patients recorded rating scales of general disc…

The Drainage System of the Paranasal Sinuses: A Review with Possible Implications for Balloon Catheter Dilation

2011

Background Intersinus connections and accessory ostia of the maxillary sinus are well known to rhinologic surgeons but are less known for the remaining paranasal sinuses. Probing and dilatation of the natural ostia of diseased sinuses is being popularized currently by the clinical value of balloon catheter dilation (BCD). Although short-term high success rates with treatment of the dilated ostia/duct have been reported with this technique, the potential impact of fractures of adjacent bony septae on accessory sinus ostia, on mucosally lined surfaces, and on intersinus drainage pathways still has not been considered. The aim of this study was to review the literature on accessory sinus ostia…

Radiation dose in non-dental cone beam CT applications: a systematic review.

2018

Background: Radiation-induced health risks are broadly questioned in the literature. As cone beam computed tomography (CBCT) is increasingly used in non-dental examinations, its effective dose needs to be known. This study aimed to review the published evidence on effective dose of non-dental CBCT for diagnostic use by focusing on dosimetry system used to estimate dose. Materials and methods: A systematic review of the literature was performed on 12 November 2017. All the literature up to this date was included. The PubMed and web of science databases were searched. Studies were screened for inclusion based on defined inclusion and exclusion criteria according to the preferred reporting ite…

Endoscope‐microscope combination for endonasal sinus surgery

1998

Endoscopic surgery of the rhinobasis with a computer-assisted localizer

1996

The endoscope is useful for the diagnosis and surgical therapy of diseases of the nose, the paranasal sinuses and its neighboring regions, and allows for microinvasive, functional approaches. The reduced invasiveness of therapeutic procedures is sometimes accompanied by insufficient clearness of the surgical field, however. This significant problem is solved by the computer-assisted-surgery (CAS) system, an intraoperative localizer. It allows continuous orientation based on three-dimensional reconstructed preoperative CT scans with superimposed positioning of the endoscope. We have now adapted CAS for endoscopic sinus surgery, which meant that a variety of visualization methods were tested.…

Hemangiopericytoma: A cause of recurrent epistaxis

2020

Hemangiopericytoma is a soft tissue tumor with histological variability and unpredictable clinical and biological behavior. this disease is uncommon in the head and neck and the growth pattern is unspecific; thus, diagnosis is often made by exclusion. A 43-year-old woman presented with a story of recurrent epistaxis associated to a growing mass in the paranasal sinus and a paraneoplastic syndrome. the imaging revealed an hypervascular tumor in the right nasal cavity and obliteration of all the ipsilateral sinus cavities. after biopsy the lesion was removed with resolution of epistaxis and paraneoplastic syndrome. There has been no evidence of disease recurrence in 3 years of follow-up. Our …

Microsurgical treatment of midfacial tumours involving the skull base

1998

Various approaches to the base of the skull for the treatment of cranial base tumours are described in detail. Advantages and disadvantages of the particular approaches are discussed. This clinical experience is based on 303 neoplasms involving the base of the skull, operated on by the authors. Retrospective survival studies are presented and a review of the literature on the subject is discussed. Utilizing microsurgical techniques the 2-, 3- and 5-year survival rates were significantly improved. The functional and aesthetic outcomes were also dramatically superior compared with standard ablative procedures. Reconstructive postoperative strategies are suggested.
