To determine the efficacy of inferior turbinate coblation for the treatment of nasal obstruction.

Twenty patients awaiting submucosal diathermy to the inferior turbinates were recruited into the study. All underwent inferior turbinate coblation. Pre-operative and post-operative nasal function was investigated using posterior rhinomanometry and subjective symptom scales.

There was no significant increase in nasal conductance two weeks after inferior turbinate coblation (p = 0.159). However, three months after inferior turbinate coblation, median nasal conductance had increased significantly, from 203 to 324 cm3/s (p = 0.004). The median increase in nasal conductance was 73 cm3/s or 43.5 per cent. Post-operative visual analogue patients' reported post-operative visual analogue scales scores for nasal obstruction decreased significantly, both two weeks (p = 0.006) and three months after inferior turbinate coblation (p = 0.001) when compared to Pre-operative values. There was no change in the reported severity of rhinorrhoea, nasal itching or sneezing. There was a significant relationship (ρ = −0.57, p = 0.014) between pre-operative nasal conductance and change in nasal conductance after inferior turbinate coblation.

This study confirms the short-term efficacy of inferior turbinate coblation for the treatment of nasal obstruction. The benefit was greatest in patients with lower pre-operative nasal conductance. Objective measures of nasal obstruction may be important when selecting patients for inferior turbinate coblation.

Although electrocautery has been used widely in surgery, the fear of delayed wound healing and infection persists. We aimed to evaluate the risk factors for wound complications and the rate of wound complications, comparing the use of electrocautery or scissors in cutaneous flap creation during thyroidectomy.

The study group comprised 239 consecutive patients scheduled for thyroidectomy.

Patients were randomly assigned to cutaneous flap dissection by either electrocautery (group one, n = 126) or scissors (group two, n = 113). Age, gender, body mass index, American Society of Anesthesiology score, tissue weight, operating time, incision length, cutaneous tissue depth, thyroid function and surgeon experience were recorded and compared with the rate of post-operative wound complications in both groups.

There were no significant differences between the overall rate of post-operative wound complications, comparing groups one and two (7.9 vs 10.6 per cent, respectively; p = 0.74). Significant positive correlations were found between wound complication and age (Spearman's rank coefficient (rs) = 0.135, p = 0.036), body mass index (rs = 0.379, p = 0.0001), cutaneous tissue depth (rs = 0.677, p = 0.0001) and tissue weight (rs = 0.643, p = 0.0001). According to logistic regression analysis, a body mass index of more than 27.5 kg/m2 was associated with a 13.7-fold increased rate of post-operative wound complications.

When creating cutaneous flaps during thyroidectomy, the use of electrocautery is as safe as the use of scissors. Such electrocautery does not increase the risk of wound complications in thyroid surgery.
