The frontal recess and frontal sinus anatomy can vary from simple to complex. The variations in the anatomy of the frontal recess and frontal sinus are considerable but almost all variations can be classified if the various cell patterns are analyzed. This consensus document was developed to improve the ability of the surgeon to understand these possible variations, plan the surgery, and communicate these complexities when teaching or reporting outcomes. Once the surgeon understands the anatomical pattern of the frontal sinus and recess cells, the extent of surgery can be planned. This document presents a classification of the extent of surgery based on the anatomical classification.

SARS CoV 2 is very much homologous in structure to SARS CoV. Review of literature suggests the in-vitro virucidal action of povidone iodine in SARS CoV and MERS. The oropharynx and nasopharynx are target sites of SARS CoV 2. A significant proportion of COVID 19 sufferers are asymptomatic, but shedding these viral particles, PVP-I has been shown to be a safe therapy when used as a mouthwash or taken nasally or used during ophthalmic surgeries. Aims:1. To propose the use of 0.5% Povidone iodine gargles and nasal drops as prerequisite for office based nose and throat examination and procedures during COVID 19 pandemic. 2. To assess tolerability of 0.5% PVP-I in patients and in healthcare workers. Materials and methods: 0.5% PVP-I solution is prepared from commercially available 10% PVP-I solution.Patients were instructed to put 0.5% PVP-I drops in nose and rinse mouth with gargle prior examinations for 30 s. For endoscopic procedure (nasal and throat) nasal douching and gargling to be started one day prior. Douching and rinsing to be repeated just before procedures. Nasal packing with 0.5% PVP-I along with 4% xylocaine/adrenaline solution, tolerability and any allergic reaction noted. Results: The patient and health care workers tolerated the 0.5%. No allergy was noted. Conclusion:We propose the use of 0.5% PVP-I in healthcare workers and their patients to minimise the risk of spread of the disease in addition to the recommended PPE.

The overall success rate for primary cartilage tympanoplasty is higher when using sliced cartilage than with temporalis fascia grafting.

Face shields are personal protective equipment devices that are to be used by many health care workers during COVID 19 pandemic for protection of the facial area and associated mucous membranes (eyes, nose, mouth) from droplet spread of infection. Face shields are generally not used alone, but in conjunction with other protective equipment like cap, mask, goggle, and are therefore classified as adjunctive personal protective equipment. In the wake of scarcity of face shields during the COVID 19 Pandemic, consideration of innovating newer methods of manufacturing must be considered to overcome the present day scarcity without jeopardising the safety of front line Heath care workers. All initial fast innovations comes with advantages and disadvantages, hence we thought of putting down simple guidelines for new emerged face shield use.

Moderate to severe obstructive sleep apnea usually requires multilevel pharyngeal surgery. Radiofrequency offers the potential of altering the upper airway on different sites.

The new techniques safely support the surgeon in locating target structures in the paranasal sinuses with little change in the actual workflow.
