Meet the Lacrimal Sac: Endoscopic Surgeons' Road Map.

Knowledge of lateral nasal wall landmarks in relation to lacrimal apparatus is essential for successful endoscopic dacryocystorhinostomy. This descriptive study of right and left sagittally sectioned ten adult cadaver head specimens was done measuring various lateral nasal wall anatomical landmarks including lacrimal apparatus with digital calipers. Maxillary line was identified in 75%, majority overlapping lacrimal sac. Genu of middle turbinate was at or posterior to nasolacrimal duct. Mean distance of superior end of sac was 8.88 mm above axilla, between its anterior edge and axilla was 10.58 mm and its length was 11.72 mm. Considering above measurements, 'Rule of 10' can be applied for nasal mucosal incision. A "Three Tier Approach" to overcome mucosal (nasal), bony (lacrimal and frontal process of maxilla) and mucosal (sac) boundaries exposes lacrimal sac up to its inferior limit ensuring successful endonasal endoscopic dacryocystorhinostomy.

Allergic Rhinitis in Relation to Food Allergies: Pointers to future research.

Allergic rhinitis is a ubiquitous type of allergic reaction which results in significant costs to affected patients and their families. Although allergic rhinitis can coexist with other atopic conditions, the role of food allergies in the development of allergic rhinitis has not been well studied. This article explores relevant literature on this subject in order to identify gaps in the available body of knowledge and elucidate scope for further research.

Clinical Study on Middle Ear Diseases in Children with Orofacial Clefts.

Introduction Orofacial clefts are associated with middle ear diseases, but the magnitude of this problem is not generally well appreciated. The aim of this study was to describe the middle ear findings and audiological profile in children with orofacial clefts. Materials and methods Children with orofacial clefts attending plastic surgery and otorhinolaryngology departments of a tertiary hospital over one-year duration were included in this study. Ninety-six children with orofacial clefts were identified. They were categorized age-wise as zero to five years, more than five years to 10 years, and more than 10 years to 15 years. They underwent a detailed ear, nose, and throat examination followed by audiological tests, including brainstem evoked response audiogram (BERA), pure tone audiogram (PTA), and tympanometry. Results Among 96 children with orofacial clefts, only 24 children (25%) had symptomatic ear problems, whereas on ear examination, 56 children (58.3%) had abnormal ear findings. Middle ear effusion (MEE) was the most common ear condition, and it was seen in 94 ears (48.9%). Cholesteatoma was noted in six children (3.1%). Out of 73 children in the zero to five age group, 58 children (79.5%) did not have any history of ear problem but 55.5% (81 ears) had features of MEE such as a dull tympanic membrane (TM). In the age group of more than five years to 10 years, only four children (28.5%) were symptomatic. Five children (55.5%) out of nine in the age group of more than 10 years had a symptomatic ear problem of which four children (44.4%) had chronic otitis media squamosal disease. The earlier age groups showed a trend of ear disease being asymptomatic compared to older children. Normal hearing was present in only 40 children (41.7%) and various degrees of hearing loss were seen in 56 children (58.3%). The mean air conduction threshold in the age group zero to five years, more than five years to 10 years, and more than 10 years were 33±8.3 decibels (dB), 25±6.2 dB, and 31.5±14 dB, respectively. Out of 144 ears (72 children) in the asymptomatic group, 67 ears (46.5%) had normal hearing. Seventy-seven ears (53.5%) had some degree of hearing loss. Mean air conduction hearing loss in the asymptomatic group was 29.8±7.3 dB. Conclusion This study highlights the higher incidence of middle ear diseases compared to the presenting symptoms in children with orofacial clefts. This stresses on the need for a detailed otological evaluation to identify any middle ear pathology so that timely intervention can be taken.

Emergency ventilation with a Chevalier Jackson's metal tracheostomy tube.

Chevalier Jackson's metal tracheostomy tube is the oldest tracheostomy tube and has survived to the present day. This is probably because it is easy to use and cost-effective. However its biggest limitation is that it lacks provision to connect to a ventilating circuit in an emergency. Here we describe a simple and effective technique for ventilation with Chevalier Jackson's metal tracheostomy tube. Ventilation can be achieved by connecting the tracheostomy tube to an appropriate size universal 15mm endotracheal tube connector. We have also worked out a formula for selection of appropriate connector for various sizes of tracheostomy tube.

Dacryocystectomy: an uncommon indication--a case report.

Post traumatic nasolacrimal drainage obstruction is an uncommon presentation of naso-orbito-ethmoid fracture. Dacryocystorhinostomy (DCR) with or without silicon intubation is the universally accepted treatment modality. Here we report a case of recurrent lacrimal sac abscess due to post traumatic nasolacrimal drainage obstruction following naso-orbito-ethmoid fracture. The patient had previously undergone incision and drainage thrice and twice failed DCR. In the background of extensive nasal synechiae and twice failed DCR, dacryocystectomy was performed. Post operatively patient has improved and is symptom free for past 14 months. This is the first report of a successful dacryocystectomy for a post traumatic dacryocystitis.

Epiglottic repositioning procedure for supraglottic stenosis/collapse.

OBJECTIVES: Supraglottic stenosis/collapse is an uncommon condition. It can be difficult to detect and may be a cause of failed decannulation following tracheostomy. We present a novel technique to correct supraglottic stenosis/collapse. METHODS: We performed a retrospective analysis of the records of patients in whom attempts at decannulation had failed at our center between 2003 and 2007. A subgroup with supraglottic stenosis/collapse with posterior displacement of the base of the epiglottis was identified. Our epiglottic repositioning procedure was performed in these patients. Through an external incision, the epiglottis was divided above the anterior commissure and attached to the superior border of the thyroid cartilage. RESULTS: Eight decannulation failures out of 36 attempted decannulations were identified. Three of these 8 cases involved supraglottic stenosis/collapse due to posterior displacement of the base of the epiglottis. Correction of the supraglottic stenosis/collapse led to successful decannulation in all cases. CONCLUSIONS: Diagnosis-directed laryngoscopy is required to identify this condition. We describe precisely a technique of repositioning the epiglottis to correct supraglottic stenosis/collapse.
