Sandwich grafting technique for endoscopic endonasal repair of cerebrospinal fluid rhinorrhoea.

The surgical management of cerebrospinal fluid (CSF) rhinorrhoea has changed significantly after the introduction of functional endoscopic sinus surgery. The clear anatomical exposure of the roof of the nasal and paranasal sinus cavities by the endoscope offers the surgeon a golden chance to identify the area of CSF leak, and thus enables one to adequately plan the management. The aim of this work is to evaluate the use of facia lata sandwich graft technique for endoscopic endonasal repair of CSF rhinorrhoea.

Role of adenoid biofilm in chronic otitis media with effusion in children.

To study the extent of surface adenoid biofilm and to evaluate its role in the pathogenesis of chronic otitis media with effusion (COME) in children. The study was carried out on 100 children between 3 and 14 years of age, who were divided into two groups. The first group (50 children) had otitis media with effusion associated with adenoid hypertrophy, whereas the second group (50 children) had adenoid hypertrophy without middle ear effusion.

Role of bacterial biofilms in idiopathic childhood epistaxis.

The objective of the study is to conduct a prospective trial investigating the possible role of bacterial biofilms in the pathogenesis of severe idiopathic childhood epistaxis. This study included 84 cases of severe idiopathic epistaxis, aged below 16 years, who were prepared for cautery under general anesthesia. A nasal swab was taken for bacterial culture and a nasal mucosal specimen (≤ 3 mm(2)) was taken from the suspected site of bleeding just prior to cautery and sent for bacterial identification by pathogen specific fluorescence in situ hybridization (FISH) and also for detection of bacterial biofilms by scanning electron microscope (SEM).

Acellular dermal (alloderm) grafts versus silastic sheets implants for management of empty nose syndrome.

The objective of the study is to conduct a prospective randomized blind clinical study comparing the efficacy and safety of use of acellular dermal (alloderm) grafts versus silastic sheets submucosal implants for management of empty nose syndrome (ENS). A total of 24 patients with a clinical diagnosis of ENS were randomly distributed in two equal groups: silastic implant group and alloderm implant group according to the type of implant used to rebuild the nose. This implant was inserted in submucoperichondrial and/or submucoperiosteal pockets fashioned along the septum, nasal floor, and lateral nasal wall.

Endoscopic management of congenital bilateral posterior choanal atresia: value of using stents.

Objective of this study is to evaluate the efficacy and safety of using stents after endoscopic repair of bilateral posterior choanal atresia. Twenty cases of congenital bilateral posterior choanal atresia were managed by endoscopic transnasal approach which was performed using a nasal stent in 10 cases and without stenting in the other 10 cases. The stent was left for 4 weeks and patients had 1-5 years of follow-up.
