This chapter explores some of the fundamental issues surrounding wound healing. It is important that perioperative practitioners understand the physiological process of wound healing as it plays a key role in the patient’s ability to maintain homeostasis and recover from surgery. A wound is any break in the continuity of the skin. Understanding the process of wound healing provides insight into understanding wound assessment and the choice of appropriate dressings and drains. The principles outlined in this chapter will apply equally to wounds caused by trauma, surgical incisions, intravenous cannulation, and invasive haemodynamic monitoring.
A systematic review was performed to evaluate the role and effectiveness of head bandages after routine elective middle-ear surgery.
Methods:
Studies that compared the effectiveness of head bandage use after elective middle-ear surgery (e.g. myringoplasty, mastoidectomy and cochlear implantation) were identified using the following databases: Ovid Medline and Embase, the Ebsco collections, the Cochrane Library, PubMed, and Google Scholar. An initial search identified 71 articles. All titles and abstracts were reviewed. Thirteen relevant articles were inspected in more detail; of these, only five met the inclusion criteria. These included three randomised, controlled trials, one retrospective case series and one literature review.
Results:
The three randomised, controlled trials (level of evidence 1b) showed no statistically significant differences in post-operative outcomes (in terms of complications) associated with head bandage use in middle-ear surgery. This finding was supported by the retrospective case series involving patients undergoing cochlear implantation.
Conclusion:
Current available evidence shows no advantage of head bandage use after middle-ear surgery. Head bandages may not be required after routine, uncomplicated middle-ear surgery.
(1) To assess hypersensitivity to bismuth iodoform paraffin paste impregnated ribbon gauze following its use in packing canal wall down mastoidectomy cavities; (2) to determine if isolation of the skin and mucosa from the pack, using thin Silastic sheeting and Cortisporin ointment, reduces hypersensitivity reactions, compared with a previous series; and (3) to review the literature and to determine if bismuth iodoform paraffin paste hypersensitivity precludes the consumption of seafood (due to its high iodine content).
Materials and methods:
All patients undergoing canal wall down mastoidectomy with intra-operative bismuth iodoform paraffin paste packing between 1985 and 2009 were identified and reviewed.
Results:
Of 587 patients identified, the overall bismuth iodoform paraffin paste reaction rate was 1 per cent. All reactions were in patients undergoing revision mastoidectomy procedures, giving a reaction rate for revision procedures of 2.4 per cent.
Conclusion:
Reactions are an uncommon event following post-operative mastoid cavity packing using bismuth iodoform paraffin paste. Reaction rates may be lowered by preparing the cavity with Silastic sheeting and Cortisporin ointment prior to packing, thus isolating the skin and mucosal surfaces. Development of such a reaction does not preclude the consumption of seafood.
The effects of packing with ribbon gauze and neuropatties on the nasal mucosa was assessed using sheep as an animal model. Fourteen sheep either underwent ribbon gauze or neuropattie nasal packing. Trauma to nasal mucosa caused by ribbon gauze and neuropatties was compared to mucosa on the lateral aspect of the middle turbinate which was not in contact with any packing. This tissue was used as a control. Ribbon gauze packing resulted in significant loss of 68 per cent of the ciliated surface of the mucosa when compared with the control group with a 15 per cent loss of ciliated surface (p < 0.005). Neuropattie packing also resulted in significant loss of 50 per cent of the ciliated surface of the mucosa when compared with the control group (p < 0.005). There was no significant difference in loss of ciliated mucosa in the specimens packed with ribbon gauze or neuropatties (p = 0.25).
Nasal packing results in a significant mucosal injury with loss of cilia. This may influence the mucociliary clearance of the nose in the post-operative healing phase. Pre-operative nasal packing should be used circumspectly and if possible avoided.
The case notes of 185 patients who had bismuth-iodoform-paraffin paste (BIPP) impregnated ribbon gauze used for packing following ear surgery were analysed retrospectively. The incidence of hypersensitive allergic reactions to BIPP was 5.9 per cent and a five-fold increase risk of developing allergic reactions was found in those with previous exposure to BIPP. Where temporalis fascia was used to repair tympanic membrane defects, the incidence of tympanic membrane graft perforations was higher when allergic reactions to BIPP developed post-operatively, compared to non-allergic cases.
